21 Professor Dr.HENRIK BALSLEV Department of Biological Sciences, Aarhus University, Denmark North-South Collaboration on Biodiversity Research – Targeting the Flora of Thailand Corresponding author, e-mail: [email protected] The term biodiversity refers to the richness and variability of life on Earth, most often referring to the number of species in a habitat, region, continent, or the whole World. But biodiversity also covers the molecular level below species and the ecosystem and biosphere levels above the species. The term was coined by Walter G . Rosen in 1985. But obviously research in biodiversity has taken place —under different names —since the beginnings of our civilizations. Taxonomic and floristic research was most strongly undertaken by the colonial powers in their quest to inventory the natural resources of their dependencies in tropical regions, now often dubbed “the South.” With the independence during the 1900s, new research institutions developed in the many former colonies. Since then, research in these countries’ biological resources, now called “biodiversity,” became a collaborative effort between the former colonial power, now dubbed “the North,” and the newly independent mostly tropical countries in the South. This North-South collaboration has involved the development of research capacity and establishment of research in biodiversity in the South. In this context, Thailand is different because it was never a colony. Nevertheless, a somewhat similar development has taken place. The relationship between Thailand and the North was based mostly on commercial exchange, but also, on the vision of King Rama V who established many political and commercial bonds between the South (Thailand) and the North (Europe). The development of the forestry sector in Thailand was part of this trend. In Botany collaboration was established between Thai forest botanist, in particular Prof. Tem Smitinand, and more traditional botanical institutions in Europe in 1965. The Flora of Thailand was initiated as an international research project in biodiversity with a South-North leadership. In the first many years the scientific input was dominated by the international collaborators from the England, Ireland, Scotland, France, Netherlands, Germany, and Denmark. But the Royal Forest Herbarium (BKF) in Bangkok provided outstanding Thai leadership and scientific production to the project. Currently the Flora of Thailand is strongly led by Dr. Kongkanda Chayamarit. As the years have passed the Flora of Thailand project has functioned as a capacity building project in biodiversity research. Currently, the overwhelming majority of contributors come from a large number of Thai academic and scientific institutions, mostly at the universities. The Flora of Thailand project will be finished within the next few years and it stands out as exemplary among North-South collaborative undertakings with a high emphasis on capacity building and gradual take-over of ownership by the South partner.

22 Professor Dr.TAN PUAY YOK Director of the Singapore Botanic Gardens, Singapore Role of the Singapore Botanic Gardens in Nature Conservation Corresponding author, e-mail: [email protected] The Singapore Botanic Gardens (SBG) is one of the oldest tropical botanic gardens, and one of only three botanic gardens in the world inscribed as a UNESCO World Heritage Site. Over its 164-year history, it has played a major role in nature conservation in Singapore and deeply influenced its environmental and social history. The shifting social, economic and political changes over the course’ of Singapore’s transformation, in turn, were impetus for the Gardens’ evolving missions—from a pleasure garden for the elites, to a botanical institution supporting imperial botany, plant discovery and taxonomy, forest conservation, greening of Singapore, and a repository and custodian of a nation’s natural and cultural heritage. Amidst these changes, the Gardens has remained steadfast its in scientific mission to advance nature conservation in Singapore and the region. In this talk, I will share the Gardens’ nature conservation work, broadly over four areas: knowing what to conserve through plant exploration and plant taxonomy, advancing conservation science through studies in rain forest biology and forest conservation research, undertaking conservation through forest restoration and species recovery, and outreach and capacity building through its capacity building programs. I will further highlight how these are fundamental to Singapore’s vision to be a City in Nature. KEYWORDS: Biodiversity; botanic garden; conservation; Singapore Botanic Gardens

23 Professor Dr. SANIT AKSORNKOAE Chairman of the National Economic and Social Development Council, Thailand Board member of The Sirindhorn International Environmental Park Biodiversity Makes a Better Life for Thai People Corresponding author, e-mail: [email protected] The Kingdom of Thailand is a country in Southeast Asia, with an area of 320 million rai, or 513,120 square kilometers, equivalent to 0.3 per cent of the total world's landmass. Strategically located in the unique geographical location and climatic characteristics, Thailand supports rich diversity of plant and animal species and microbial diversity, ranked in the top ten of the most biodiverse countries in the world. Thai people settled in coastal zones, plains, and mountainous areas are bound to depend on the availability and use of biodiversity for improving their wellbeing, particularly in meeting the basic needs that include, amongst others, shelters, food, medicines, and clothing. Biodiversity of coastal and marine habitats, as well as that of inland ecosystems, also provides recreation and leisure services derived directly from biological resources such as forests, wildlife, and coral reefs. Biodiversity is essential for maintaining an ecosystem balance. These rich biodiversity and ecosystem services enable Thailand to generate economic and social values in a sustainable manner, and enhance the country’s competitiveness in emerging fields such as green jobs, green and clean technologies, and sustainable tourism. In addition, protecting biodiversity plays a crucial role in achieving carbon emission reductions, contributing to climate change mitigation and disaster risk management and resilience. Some ecosystems and their biodiversity, such as forests and coastal habitats, are particularly efficient for carbon sequestration and help reducing the concentration of carbon in the atmosphere. Mangroves, seaweeds, and seagrasses provide crucial buffers to extreme storms and flooding related to climate change. It is a fact that Thailand’s unique biodiversity is threatened and continuously declining. The Royal Thai Government has developed national policies, measures, and plans for conservation, protection, and sustainable use of the country’s biodiversity and ecosystem services. Efforts are also undertaken to enhance the benefits from them, along with raising public awareness and understanding of the roles and importance of biodiversity to human well-being, and collaborating with all relevant sectors and stakeholders in integrated ecosystem management and biodiversity protection including application of three principles , namely ,Sufficiency Economy Philosophy (SEP) , BCG Economy , and Sustainable Development Goals (SDG) for the better life of our future generations.

25 Dr.ROBERT G COLES Centre for Tropical Water & Aquatic Ecosystem Research (TropWATER) James Cook University, Australia Managing and Protecting Seagrass Resources in the Tropics in the Face of Climate Change- Lessons from Research in Northern Australia Corresponding author, e-mail: [email protected] ABSTRACT: Recent severe storms and floods in north- eastern Australia damaged or destroyed seagrass meadows along hundreds of kilometres of coastline. The subsequent deaths of turtles and dugong and loss of fisheries values have contributed to the status of our iconic Great Barrier Reef World Heritage Area being at risk. As scientists we are now being challenged by these events to provide effective advice to governments, protect the ecological services provided by seagrass meadows and to mitigate the impacts of climate change. How and when will impacted meadows recover if at all and should onground mitigation and interventions such as re-planting be considered? We are lucky in tropical northern Australia to have an extensive seagrass mapping and monitoring program extending back to the early 1980s. This has enabled us to look at how seagrass communities distribute spatially and in many cases how they have changed through time and if they meet a concept of “desired state” based on historical records. We have also developed an understanding of how meadows may re-establish from the dispersion of propagules floating in the water or moved by feeding herbivores such as Dugong and turtles. We have been able to use numeric models for studying water movement to investigate connectivity among meadows and the role different meadows are likely to play in natural recovery. This has allowed us to identify seagrass hotspots where propagules from many source meadows accumulate and natural re-establishment would be likely and other locations where interventions may be necessary. We report on the management implications of this research and the gaps that need to be filled by future programs.

26 Dr. SHUN KOBAYASHI Faculty of Science, University of the Ryukyus, Okinawa, Japan Importance of Squirrels as Pollinators in Asia Corresponding author, e-mail: [email protected] ABSTRACT: In tropical Asia, insects, particularly bees, are recognized as vital pollinators. However, the role of other animals in plant pollination cannot be overlooked. In this study, we shed light on non-flying mammalpollinated plants in Asia, an area where relatively little research has been conducted. By reviewing relevant literature, we have identified 33 non-flying mammals known to serve as pollinators in this region. Among these mammals, members of the Sciuridae (squirrel) family, particularly those belonging to the Callosciurinae subfamily, are the most commonly recorded pollinators. Furthermore, we have identified 20 plant species that rely on non-flying mammals for pollination, with 19 of them being pollinated by squirrels. For these plants, squirrels appear to be the primary and non-alternative pollinators. The Callosciurinae subfamily has notably diversified in tropical Asia, suggesting a potential link between the evolution of Callosciurinae and the evolution of non-flying mammal-pollinated plants in this region. In addition, we conducted a comparative analysis of the pollination systems of Mucuna (Fabaceae), a genus with some species that are pollinated by non-flying mammals in Asia, with those of other genera also featuring non-flying mammal-pollinated plants. While the floral shapes and colors of these plants are similar, Asian Mucuna species tend to secrete nectar during the daytime and their pollinators are diurnal. This phenomenon may be unique to Asia, where there is a notable reliance on squirrels for pollination services. This research highlights the significance of non-flying mammals, particularly squirrels, as pollinators in the ecosystems of tropical Asia and provides insight into the coevolution of these mammals and the plants they pollinate. KEYWORDS: Callosciurinae; non-flying mammals; pollination; tropical Asia.

Mangrove forests are widely distributed in 128 tropical and subtropical nations and territories. Mangrove ecosystems provide an array of essential ecosystem goods and services, which contribute significantly to the livelihoods well-being and security of coastal communities. Mangroves are recognized as an important ecosystem in the context of national and global development and environment objectives, including the 2030 agenda for sustainable development. We planted mangrove to abandoned shrimp ponds for rehabilitation and new mudflats areas for carbon sequestration in Nakhon Si Thammarat, Thailand. Mangrove ecosystems have been a focus on mangrove trees and crabs in mangrove ecosystem-related studies, and on commercially exploited species (e.g., prawns and mangrove trees). In terms of fauna, there has been a shift to gather information on their benthic invertebrates. Generally, food webs in the nature have multiple, reticulate connections between a diversity of consumers and resources. The importance of mangrove ecosystems as nursery ground for juvenile fishes. Many tropical fish species are spending part of their life cycles in mangrove swamps or are dependent on food chains which can be traced back to these coastal mangrove forests. Despite years of research on the habitat use and feeding ecology of many abundant estuarine animals, we still do not know which autotrophs form the base of food webs that support high levels of secondary productivity in estuaries. Stable isotopic study method can present time-integrated information on organic carbon sources for heterotrophs and feeding relationships, mainly using stable isotopes ratios of carbon and nitrogen in organism for biodiversity of mangrove ecosystems.

30 Dr.SUVIT MAESINCEE Former Minister of Higher Education, Science, Research and Innovation of Thailand. Making Sustainability Sustainable Corresponding author, e-mail: [email protected] ABSTRACT: We all have witnessed not only deadly floods and droughts, intensified heat waves, epidemics and pandemics, emerging and re-emerging diseases, but also flowers blossoming in Antarctica, invasive blue crabs threatening the Italian economy, and cold snow blankets the Sahara desert for the first time in 42 years as a result of climate change. Awakened by reality, we must make sustainability sustainable. As we know, the United Nations’ SDGs are our shared vision to recreate a better world and an inhabitable planet. Thus far, the weak point of SDGs is not its purpose, but its execution. This presentation will propose a strategic yet pragmatic approach to making the United Nations’ Decade of Action come true. To make transformative change happen, the Bio, Circular & Green (BCG) economy model will be introduced as the strategy to revolutionize our current economic system. Finally, human civilization in the making will be addressed to propose a new set of values to live in harmony with Nature and with others. KEYWORDS: BCG Economy Model, SDGs

31 Professor Dr. GORDON S. MAXWELL FRSB Hong Kong Metropolitan University, Hong Kong Sustainability in Action: Mangroves as Eco-engineers Corresponding author, email: [email protected] ABSTRACT This paper reports a case study of how mangrove forests can be used, appreciated and valued by engineers, government at all levels (local, regional and national), dairy farmers, mangrove scientists and citizens to protect economic assets. The site is the Hauraki District in the rich farming Waikato region of New Zealand. Here man-made stop banks which protect the low-lying farmland beside the twin estuarine rivers of Paiko and Waihou are themselves protected by belts of mangrove forest. A double protection: stop banks protect the farmland and mangroves protect the stop banks. There protective role may grow in importance as sea level rise and storm-driven tidal invasions increase in frequency. Some 64,000 ha (= 400,000 rai) of top dairy farmland worth NZ $ 34,264 per ha give the economic stamp of importance to the Hauraki Plains. A conservative sum of 2.2 billion NZ dollars (46.5 billion Thai Baht) worth of rural land assets owes their cost-free protection to the sole NZ mangrove species, Avicennia marina. This compact tree is an eco-engineer in action and helps local catchment and drainage authorities to save lots of money on stop bank maintenance and re-building. The mangroves do it for free. Moreover, this mangrove species forms a self-sustaining ecosystem. Additional economic positives directly and ecologically linked to mangroves include their place in coastal fisheries. Mangrove honey presents an inviting opportunity for some in New Zealand to learn from the mangrove honey harvesters of developing countries such as those who inhabit the Sundarbans. The harvest of honey will add even more economic clout to mangrove resources. All this is a demonstration is real sustainability in action. By placing a direct $ value on what they do enables us to quantify sustainability provided by an ecosystem. Clearly, mangroves as eco-engineers are playing their part in sustainable economic development and are part of the system. KEYWORDS: Billions in value; eco-engineers; estuarine rivers; low-lying farmland; mangrove forest; sustainability in action.

32 Professor Dr.DONALD J. MACINTOSH Adjunct Professor, School of Environment, Resources and Development, Asian Institute of Technology, Pathum Thani 12120, Thailand. Payment for Ecosystem Services (PES) as a Green Economy Incentive Mechanism to Conserve Habitats and Biodiversity Corresponding author, e-mail: [email protected] ABSTRACT: Payment for Ecosystem Services (PES) is a financing mechanism whereby households or communities that protect habitats and biodiversity (=environmental service providers) receive payments from the beneficiaries of the protected ecosystem services (=service users). PES mechanisms require that the service users and service providers are clearly identified; and that they can be matched together in a way that enables providers to receive payments from users for specific, measurable, and sustainable environmental services. Use of PES is well-established in terrestrial forest habitat and biodiversity conservation. However its application to mangroves and other coastal ecosystems is more challenging because of the open and interconnected nature of the habitats involved; the dynamic nature of coastal processes, including impacts from storms and climate change; and the multitude of mangrove-associated ecosystem services accessed by both resident and non-resident users. Thus, not surprisingly, there are few examples of PES systems operating well to safeguard coastal biodiversity in Southeast Asia. In the case of mangrove restoration and conservation, government and donor-supported projects, or CSR support from the private sector, have been the traditional financing mechanisms. An example of a successful coastal PES initiative is described. This was initiated from a project that assisted shrimp farmers in Ca Mau, southern Vietnam to maintain at least 50% mangrove cover in their integrated mangrove-aquaculture ponds. They were also taught to adopt hygienic shrimp farming methods without the use of chemicals. In return, the processing companies buying the shrimp (the service users) pay a higher price to the farmers’ (the service providers) because the shrimp can be certified as organic and sold in premium international markets. Moreover, the diversity of other mangrove-associated aquatic species as a secondary crop also increased. In addition, farmers also receive payments from the Vietnamese Government for mangrove forest protection. Since 2018, Vietnam has enacted a decree on Forest Environmental Services that provides a legal basis for PES contracts between forest service providers and the users of water resources, ecotourism services and aquaculture products. The same project also cooperated with mangrove aquaculture farmers in Trat, Chanthaburi and Samut Prakan, but with a somewhat different focus and outcomes. Farmers were mainly assisted to make their pond production methods more sustainable. Because of the strong demand for seafood in Thailand, farmers preferred to sell into premium domestic markets, with the advantage that they could more easily achieve the Department of Fisheries quality standards for organic seafood in Thailand. Recent developments with the adoption of PES-like mechanisms for forest management in Thailand, including mangroves, will also be presented.

China 2 Faculty of Social Science, Chiang Mai University, Chiang Mai, 50100, Thailand Biodiversity of Honey Bees and International Collaboration *Corresponding author, e-mail: [email protected] ABSTRACT: Biodiversity is a topic of widespread contemporary discourse, prominently underscored by the international community within the framework of “sustainable development,” continuously under scholarly scrutiny in the context of “multispecies sustainability” research, and actively cultivated in the realm of rural development in China under the banner of “ecological civilization.” The nine species of honey bees include Apis cerana, Apis laboriosa, Apis dorsata, Apis andrenifoemis, Apis florea, Apis koschevnikovi, Apis nigrocincta and Apis mellifera. In the context of China, the apiculture sector has responded to both national and United Nations appeals by actively integrating “diversity” into its various facets. Chinese volunteers, fueled by their intrinsic passion, have successfully compiled photographic records of different wild-growing bee species, consistently monitoring and comprehending the intricacies of their ecological viability. This multifaceted endeavor has garnered recognition from international, and concurrently, has furnished invaluable empirical data for research, particularly in the domain of non-domesticated bees, with a particular focus on the Asian sphere. Simultaneously, China has taken proactive measures to engage in international collaboration, facilitated through platforms such as the “Asian Apiculture Association,” fostering closer ties among the diverse cultures and bee species across the Asian region.

35 José Paulo Sampaio UCIBIO, Departamento de Ciências da Vida, Faculdade de Ciências e Tecnologia, Universidade Nova de Lisboa, Caparica, Portugal TRAVELLING THROUGH THE UNSEEN BIODIVERSITY, A PERSONAL ACCOUNT Corresponding author, e-mail: [email protected] ABSTRACT: Although most of the focus on the loss of biodiversity is directed towards plants and animals, an unseen microbial majority also requires the attention of scientists and policy makers. Microorganisms are ubiquitous in nature where they play fundamental roles, whose outcomes sustain all other life forms on Earth. They are the life support system of the biosphere, being essential for the global food web and for the cycling of carbon, nitrogen, and other elements necessary for life. Microbial communities are also essential for many ecosystem functions. Most importantly, our current understanding of how microbial communities are affected by ecosystem alterations is insufficient to tackle important challenges such as those posed by climate change. Through several international collaborations in different parts of the world, including Thailand, I have explored the diversity and ecological particularities of a unique microbial group: yeasts, which are a biotechnologically important but ecologically poorly understood group of fungi that are predominantly unicellular. In Thailand, these collaborations allowed for a better understanding and preservation of important genetic resources such as wild lineages of Saccharomyces cerevisiae, whose immense biotechnological applications could benefit from the untapped diversity being revealed in wild lineages discovered in Thailand.

37 Taxonomic revision of genus Balanophora with a new record from Thailand Natthapruek Sakdapipanich1 , Sittiporn Singnalintorn1 , Thanasett Kittiwatthanothai1 , and Jiroat Sangrattanaprasert1,* 1Mahidol Wittayanusorn School, Phutthamonthon, Nakhon Pathom, Thailand *Corresponding author, e-mail: [email protected] ABSTRACT: The genus Balanophora, a root-holoparasite, is predominantly distributed across tropical Africa, temperate to tropical Asia, Australia, and the Pacific Islands. Remarkably, this enigmatic genus exhibits noteworthy medicinal properties, including HIV inhibitory, hypoglycemic, anti-inflammatory, and analgesic effects, which have found diverse applications. While a taxonomic account of Thai Balanophora, encompassing five taxa, was previously chronicled in the esteemed Flora of Thailand vol. 2, part 2 by Hansen (1972), recent progress made by MWIT researchers have led to the publication of a new record from herbarium specimens, last year. However, an intriguing predicament remains; numerous collected specimens housed within Thai herbaria remain either unidentified or misidentified. In response to this knowledge gap, our research seeks to embark on a comprehensive taxonomic revision of the genus in the Thai flora. Our primary objectives are twofold: (1) to provide additional descriptions and distribution ranges for the identified taxa, and (2) to present an updated taxonomic account alongside a dichotomous key for the species found in the Thai flora. During the course of this taxonomic revision, our team was greeted with an exciting discovery – a new species record, namely B. papuana Schltr., contributing significantly to the rich diversity of Balanophora in Thailand. Such findings bear substantial implications for the study of Balanophora taxonomy and unlock new potential applications. The newly reconstructed dichotomous key, encompassing all Thai taxa, represents a valuable tool that shall bolster future research endeavors and conservation initiatives. Moreover, the unveiling of B. papuana not only enriches our comprehension of the genus distribution but also accentuates the criticality of perpetuating exploration and taxonomic investigations within biodiversity hotspots, such as Thailand. This newfound understanding may pave the way for exciting prospects in the field of botanical research and its practical ramifications.

Sampling was conducted from April to May 2021 in eight sampling stations namely; Malinao, Catangnan, Pilaring, Caridad, Tigasao, Pacifico, Baybay and Poblacion 1. Macroalgal species were identified based on external morphological characteristics and a total of 62 species were reported in this study, encompassing 29 Chlorophyceae, 18 Phaeophyceae and 15 Rhodophyceae. The macroalgal community in Eastern Siargao ranged from moderate to highly diverse and it was dominated by three species namely: Portieria hornemannii, Tricleocarpa fragilis and Gelidiella acerosa. This study was significant because it provides additional information on seaweed flora of Southern Philippines. Moreover, this is the first detailed seaweed account in Siargao Island hence it filled the gap in the phycological diversity and distribution map of the Philippines.

39 Morphological and genetic analysis of stingrays in the Telatrygon complex in Thai waters Titirat Meejan1 Sitthipon Tippinwong1 , Tassapon Krajangdara2 , Jenjit Khudamrongsawat3 , and Wansuk Senanan1 1Department of Aquatic Science, Faculty of Science, Burapha University, Chonburi 2Phuket Marine Fisheries Research and Development Center, Department of Fisheries 3Department of Biology, Faculty of Science, Mahidol University, Bangkok ABSTRACT: Stingrays in the Family Dasyatidae recently underwent a taxonomic update in 2016, describing several novel genera and 3. The genus Telatrygon was recently named as a separate group from the Dasyatis. In Thai waters, which encompasses the Pacific Ocean (Gulf of Thailand) and the Indian Ocean (the Andaman Sea), Last et al. (2016) proposed two additional species to a commonly recognized T. zugei (Müller & Henle, 1841) (former D. zugei), namely T. crozieri (Blyth, 1860), and T. biasa Last, White & Naylor, 2016. Kajangdara et al. (2022) report that T. zugei is present in both the Gulf of Thailand and the Andaman Sea, T. biasa is only present in southern Thailand (both seas), and T. crozieri is in the Andaman Sea. However, specimens included in these reports did not represent the entire Thai waters. In addition, the diagnostic characteristics considerably overlap among these species. Therefore, this study aimed to clarify the Telatrygon complex in Thai waters based on 39 morphometric characteristics in addition to 7 diagnostic characteristics and nucleotide sequence variation (Cytochrome oxidase subunit I (COI), and NADH dehydrogenase subunit 2, ND2). For morphometric measurements and genetic analysis, we examined 33 and 55 specimens obtained from fish landing ports and research vessels in the Gulf of Thailand (20 and 24 individuals) and the Andaman Sea (13 and 31 individuals). Initially, these specimens were identified into three morpho species based on seven diagnostic characteristics (which often involved snout length, disc length/width and interorbital length). Principal component analysis (PCA) suggested at least two clusters, with Group 1 consisting of mostly T. biasa and Group 2 consisting of T. crozieri, T. zugei, and T. biasa. The K2P genetic distances between the specimens from the Gulf of Thailand and the Andaman Sea were 0.005±0.002 (COI) and 0.015±0.003 (ND2). Furthermore, based on the nucleotide sequences variation, all samples in this study were genetically distinct from T. zugei from Taiwan and Vietnam (genetic distance = 0.014 – 0.018 for COI and 0.029 - 0.034 for ND2). In this study, specimens from the Gulf of Thailand are likely T. biasa, while samples from the Andaman Sea are still inconclusive. Our results suggested that the distribution of T. biasa extends to the upper Gulf of Thailand. Additional specimens representing all morpho species in the Gulf of Thailand and Andaman Sea are required to clarify whether the three species co-occur in the Andaman Sea and whether T. zugei occurs in the Gulf of Thailand. High-resolution genetic markers may also be critical to distinguish more closely related species (e.g., T. zugei vs. T. crozieri). The data obtained from this study contribute to the understanding of taxonomic relationships in the Telatrygon complex in Thailand, supporting the National Plan of Action for Conservation and Management of Sharks, Thailand (NPOA-Sharks).

Rifampin was used as a screening filter to isolate novel ansamycin-specific scaffolds from actinomycetes. 3-Amino-5-hydroxybenzoic acid synthase (AHBA)-encoding gene (rifK) was used to identify the potential ansamycin-derivative producers and classify types of ansamycin derivatives from the acquired rifampin-resistant isolates. Three out of 61 isolates, accounting for approximately 5%, were found to contain rifK. Among these 3 rifK-positive strains, two of them, namely isolate 505 from Cissampelos pareira and CM201R from Caryota mitis were active against the test microorganisms, including Gram-positive and Gram-negative bacteria as well as non-filamentous fungi. Preliminary screening using LC-MS/MS analysis of the crude extract from isolate 505 revealed the possible novel ansamycin derivative, while the classical rifampin was detected from isolate CM201R. Using 16S rRNA gene sequencing, both isolate 505 and CM201R were primarily identified as members of the genus Amycolatopsis with approximately 99% similarity. Digital DNA-DNA hybridization values and average nucleotide identities (ANIs) between these two strains and the closet type strains confirmed that each strain represented a novel species. The polar lipid profile of both isolate 505 and CM201R consisted of the typical polar lipids for members in the genus Amycolatopsis, including phosphatidyl ethanolamine, diphosphatidylglycerol, phosphatidylglycerol, and phosphatidylinositol. The diagnostic diaminopimelic acid of peptidoglycan was meso-diaminopimelic acid. The major fatty acids were iso-C16:0, C16:0, isoC15:0 and anteiso-C17:0 for isolate 505, while those of isolate CM201R were iso-C16:0, C16:0, anteisoC17:0 and iso-C15:0. Taking into account these results, strain 505 and CM201R are to be proposed as the type strains of the novel Amycolatopsis species.

Globally, there has been a rapid increase in blue carbon research in the last few decades, with extensive plans and strategies by the European Union, the USA, Australia, Seychelles, and Belize. Blue carbon ecosystems in Thailand, especially seagrass ecosystems represent high potential for carbon sequestration and sinks within the region. Currently, the research on blue carbon in seagrass meadows is the highest in Thailand compared to other countries in the region. Furthermore, seagrass meadow at Libong Wildlife Sanctuary in Trang have been identified as a regional blue carbon hotspot with high potential of organic carbon storage. Although the blue carbon research has been expanding in Thailand,the focus on the several topics is still lacking, such as carbon and other greenhouse gas emissions, carbon sequestration and burial rates, improvement of spatial bias of sampling, and incorporation of remote sensing to map seagrass meadows and their stocks across large spatial scales. The recent study corrected spatial sampling bias across different seagrass ecosystem including not only high spatial but also temporal variability to provide more accurate assessment of national organic carbon stocks. The results highlight the complexity of blue carbon in seagrass meadows in Thailand and the associated impacts on national blue carbon assessments, carbon accounting, and conservation strategies. As Thailand is moving towards Net Zero policies and strategies, the improvement of the current assessments should be considered as well as filling up the highlighted gaps of knowledge of various topics related to seagrass blue carbon.

46 Resilient coral communities on underwater pinnacles to climate change in the Gulf of Thailand Thamasak Yeemin1,* , Makamas Sutthacheep1 , Sittiporn Pengsakun1 , Wanlaya Klinthong1 , Wiphawan Aunkhongthong1 , and Paphanaphak Prakopphon1 1Marine Biodiversity Research Group, Department of Biology, Faculty of Science, Ramkhamhaeng University, Huamark, Bangkok, 10240, Thailand *Corresponding author, e-mail: [email protected] ABSTRACT: The survival of coral reefs in tropical seas is threatened by the impacts of climate change, particularly severe coral bleaching events. Coral communities on underwater pinnacles in the Gulf of Thailand are important marine ecosystems that provide similar ecosystem services as coral reefs. The community structure of the underwater pinnacle influences the diversity and composition of reef-associated organisms. This study aimed to examine resilient coral communities on underwater pinnacles in Surat Thani Province, the Western Gulf of Thailand following several mass coral bleaching events during the past decades. The coral communities on 35 underwater pinnacles were assessed by using a permanent belt transects method. Our results revealed that high diversity of Scleractinian corals was found at several underwater pinnacles. There were significant differences in coral covers at the study sites. The highest species diversity index of corals was observed at Hin Kong Sai Daeng, followed by Hin Samran, Ao Hin Wong, Hin Chumphon, White Rock, and Hin Tungku. The highest live coral coverage was found at Hin Kong Sai Daeng (41.09±14.17%) while the lowest one was recorded at Hin Tungku (18.75±6.46%). The common coral species at all study sites were Montipora aequituberculata, Diploastrea heliopora, Pocillopora acuta, Porites lutea, Platygyra sinensis and Pavona decussata. This study provides an assessment methodology and identifies certain underwater pinnacles that are a high potential to be promoted and developed for ecotourism sites in the Western Gulf of Thailand. Besides tourism, the underwater pinnacles can be marine protected areas for enhancing marine biodiversity. Local participation and co-management are needed for managing the effective use of these underwater pinnacles under the crisis of climate change.

47 Resilient Blue Carbon: Adaptive Strategies for Securing the Blue Carbon Potential of Mangrove Ecosystems Michael Jenke1,2,* and Aor Pranchai1,2 1Special Research Unit for Mangrove Silviculture, Faculty of Forestry, Kasetsart University, Chatuchak, Bangkok 10900, Thailand 2Department of Silviculture, Faculty of Forestry, Kasetsart University, Chatuchak, Bangkok 10900, Thailand *Corresponding author, e-mail: [email protected] ABSTRACT: Sea-level rise (SLR) poses a significant challenge to mangrove ecosystems, which are essential sinks of blue carbon — the carbon stored and sequestered in coastal ecosystems. These ecosystems are vital in climate change mitigation due to their capacity to sequester and permanently store large amounts of atmospheric carbon. The unique environmental tolerances, regeneration, growth potential, and other functional traits of different mangrove species necessitate a comprehensive adaptation strategy to SLR. In this conceptual study, we design an adaptation framework tailored to protect and enhance the blue carbon potential of mangroves. The framework encompasses (1) the functional traits of mangroves, focusing on their role in blue carbon sequestration, (2) the vulnerability to SLR considering exposure, sensitivity, and adaptive capacity, and (3) the efficacy of adaptive measures in preserving blue carbon stocks. We found that resistance-oriented adaptive measures could protect mangroves from SLR, thereby safeguarding their blue carbon capacity through promoting sediment accretion, reducing erosion, and nurturing overall forest health. Resilience-oriented measures facilitate mangrove recovery from SLR, thus sustaining the carbon sequestration process, while transformation-oriented measures enable the expansion of mangroves into new areas, potentially increasing blue carbon reserves. Our analysis highlights the need for species- and site-specific strategies in coastal management plans. A generic approach may lead to a loss in blue carbon capacity if less adaptive species are replaced by more adaptive ones. Additionally, potential maladaptive measures, such as focusing solely on monoculture plantations, could further erode blue carbon potential. In conclusion, our conceptual framework offers an innovative approach for preserving the blue carbon reservoirs of mangroves in the face of SLR. It emphasizes the importance of multifaceted adaptive measures that are sensitive to the particularities of different mangrove species and local conditions. Further empirical research is required to validate this approach in specific locales, providing a foundation for its application in other coastal forest ecosystems where blue carbon sequestration is vital.
