- Fisheries Administrative Order No. 233: Series of 2010. Aquatic wildlife conservation.(Department of Agriculture, 2010-04-16)This Administrative Order, consisting of 5 Chapters and 1 Annex, In line with Rule 37.1 of the Joint DENR-DA-PCSD Administrative Order No. 1, Series of 2004, is promulgated pursuant to Republic Act 9147 or the Wildlife Resources Conservation and Protection Act of 2001. It creates several authorities entitled to carry out research, control and manage the aquatic wildlife sector, such as: the National Aquatic Wildlife Management Committee (NAWMC) and establishes their composition, duties and responsibilities. This Order is divided as follows: Structures and Individuals for the Conservation of Aquatic Wildlife (Chap. I); Utilization of Aquatic Wildlife (Scientific Research on Aquatic Wildlife) (Chap. II); Fees and Charges (Chap. III); Fines and Penalties (Chap. IV); Miscellaneous Provisions (Chap. V). The Annex lays down a Preliminary List of Economically Important Aquatic Organisms.
- Mining small molecules from Teredinibacter turnerae strains isolated from Philippine TeredinidaeVillacorta, Jamaine B.; Rodriguez, Camille V.; Peran, Jacquelyn E.; Batucan, Jeremiah D.; Concepcion, Gisela; Salvador-Reyes, Lilibeth A.; Junio, Hiyas A. (MDPI, 2022-11-21)Endosymbiotic relationship has played a significant role in the evolution of marine species, allowing for the development of biochemical machinery for the synthesis of diverse metabolites. In this work, we explore the chemical space of exogenous compounds from shipworm endosymbionts using LC-MS-based metabolomics. Priority T. turnerae strains (1022X.S.1B.7A, 991H.S.0A.06B, 1675L.S.0A.01) that displayed antimicrobial activity, isolated from shipworms collected from several sites in the Philippines were cultured, and fractionated extracts were subjected for profiling using ultrahigh-performance liquid chromatography with high-resolution mass spectrometry quadrupole time-of-flight mass analyzer (UHPLC-HRMS QTOF). T. turnerae T7901 was used as a reference microorganism for dereplication analysis. Tandem MS data were analyzed through the Global Natural Products Social (GNPS) molecular networking, which resulted to 93 clusters with more than two nodes, leading to four putatively annotated clusters: lipids, lysophosphatidylethanolamines, cyclic dipeptides, and rhamnolipids. Additional clusters were also annotated through molecular networking with cross-reference to previous publications. Tartrolon D cluster with analogues, turnercyclamycins A and B; teredinibactin A, dechloroteredinibactin, and two other possible teredinibactin analogues; and oxylipin (E)-11-oxooctadec-12-enoic acid were putatively identified as described. Molecular networking also revealed two additional metabolite clusters, annotated as lyso-ornithine lipids and polyethers. Manual fragmentation analysis corroborated the putative identification generated from GNPS. However, some of the clusters remained unclassified due to the limited structural information on marine natural products in the public database. The result of this study, nonetheless, showed the diversity in the chemical space occupied by shipworm endosymbionts. This study also affirms the use of bioinformatics, molecular networking, and fragmentation mechanisms analysis as tools for the dereplication of high-throughput data to aid the prioritization of strains for further analysis.The research was completed under the supervision of the Department of Agriculture-Bureau of Fisheries and Aquatic Resources (DA-BFAR), Philippines in compliance with Prior Informed Consent (PIC) certificate requirements and all required legal instruments and regulatory issuances covering the conduct of the research. The authors would also like to acknowledge the Department of Science and Technology-funded Discovery and Development of Health Products Program (DOST-DDHP) for the LC-MS Facility of the Institute of Chemistry, University of the Philippines Diliman.
- A multi-framework analysis of stakeholders’ perceptions in developing a localized blue carbon ecosystems strategy in Eastern Samar, PhilippinesQuevedo, Jay Mar D.; Ferrera, Charissa M.; Faylona, Marie Grace Pamela G.; Kohsaka, Ryo (Springer Science and Business Media LLC, 2024-01-25)Blue carbon ecosystems (BCEs) are vital for global climate change mitigation and offer diverse local ecosystem co-benefits. Despite existing literatures on integrating national and international BCE agendas at the local level, the development and implementation of localized BCE strategies often lag behind. To provide insights on this knowledge gap, we present a case study conducted in Eastern Samar, Philippines. Employing a multi-framework analysis- encompassing DPSIR (drivers, pressures, state, impact, responses), SOAR (strengths, opportunities, aspirations, results), and PESTLE (political, economic, social, technological, legal, environmental) frameworks, stakeholder perceptions collected from focus group discussions highlight issues and challenges in developing and implementing a BCE strategy. Findings reveal that the aftermath of Typhoon Haiyan in 2013 in the study sites stimulated conservation efforts and raised awareness, but governance structures and policy enforcement influence the success and longevity of management and conservation efforts. Through the integration of multiple frameworks, this study outlined a potential localized BCE strategy, emphasizing both internal priorities such as stakeholder engagement and alternative livelihoods and external priorities related to policy and technological supports. While developed based on a specific case study in the Philippines, the proposed strategy is presented in a general manner, enabling its potential replication in other provinces in the Philippines or in countries with similar geographic settings.
