Abstract (sommario):

SUMMARYLittle is known about local extinctions of finfish species in the most biodiverse marine ecosystem in the most marine biodiverse and anthropogenically threatened region on Earth. This paper examines coral reef associated finfish species that disappeared in the catches around the island of Bohol over the period 1950 to 2007, based on the only available data, namely traditional ecological knowledge. Generalized least squares (GLS) tests showed steep declines to zero among species formerly recorded in catches. Finfish species recommended as priority for further monitoring based on life history and disappearances in fish catch are giant grouper (Epinephelus lanceolatus) and African pompano (Alectis ciliaris). Twenty out of the 21 species that disappeared from catches were moderate to very large-bodied, six were slow-growing fish and four were late-maturing fish. Species of large body size and subject to high fishing pressure may be particularly vulnerable. Traditional ecological knowledge when applied to population dynamics studies can add value to development of new monitoring methods. This knowledge can moreover inform the prioritization of species for fisheries assessment and conservation action.

Abstract (sommario):

For over two centuries there were no records of Blue Whales Balaenoptera musculus in the Philippines. Whalers recorded Blue Whales in the Philippines in the 19th century, and the next confirmed sighting in the country was of a mother and calf in 2004. Since then 33 subsequent Blue Whale sightings of potentially one individual were recorded between 2004 and 2019, all within the central region of the Philippines around the Bohol Sea. This individual, recognized through photo-identification, was sighted on at least 13 occasions during eight different years: 2010, 2011, 2012, 2015, 2016, 2017, 2018, and 2019. The geographic location and timing of the sightings (January to July) suggest that Blue Whales in the Philippines may extend the outer range edge of the Indo-Australian population that migrate between western Australia, Indonesia, and East Timor. Blue Whale sightings in the Bohol Sea coincide with times of high ocean productivity, although further investigation is needed to determine if they are actually feeding in this region. Acoustic studies and photo-identification matching with other Blue Whale catalogues will clarify the stock identity of Blue Whales in the Philippines and their relation to the rest of the Blue Whale population, with implications for the conservation of this endangered species across multiple jurisdictions.

Abstract (sommario):

SummaryBetween June 1989 and October 1990 casual records of rare birds were made in Sabah and on Sipadan Island, Malaysia, and on Luzon, Negros, Bohol and Mindanao, Philippines, with additional observations on Palawan and Tawitawi, Philippines, in August and September 1991. Key sites for bird conservation profiled here are the Angat watershed, Quezon National Park and Candaba Marsh (all on Luzon), Mt Canlaon (Negros), Rajah Sukituna National Park (Bohol), Mt Katanglad (Mindanao), remaining forest on both Tawitawi and Sipadan, and the Danum Valley in Sabah. Notes are provided on 31 species of bird, 17 already considered threatened, three near-threatened. While one threatened species (Nicobar Pigeon Caloenas nicobarica) should be downlisted, at least six species (Spotted Imperial-pigeon Ducula carola, Blue-winged Racquet-tail Prioniturus verticalis, Blue-naped Parrot Tanygnathus lucionensis, McGregor's Cuckoo-shrike Coracina mcgregori, Falcated Wren-babbler Ptilocichla falcata and Palawan Flycatcher Ficedula platenae) should be elevated to threatened status. Records for other species supplement and reinforce current assessments of threat or indicate new distributional or taxonomic information on non-threatened forms.

Abstract (sommario):

The study assessed the present vegetation composition of the Proposed Site for the Tarsier Tourism Center (PTTC) at Villa Aurora, Bilar, Bohol and performed a comparative analysis with the existing Tarsier Sanctuary (TS) at Canapnapan, Corella, Bohol. The basis for comparison was the computed importance values, species richness, species dominance, and percent distribution of plants according to self-defined DBH classes. Results showed that both sites had very high species richness and evenness values. Common overstorey and understorey plant species found in both areas were katagpo (Psychotria sp.), sagimsim (Syzygium brevistylum [C. B. Rob]Merr.) and bagauak (Clerodendrum minahassae Teijsm. & Binn.). Apart from sagimsim (Syzygium brevistylum [C.B.Rob.] Merr.), selaginella (Selaginella cuppresina Lin.), and lunas (Lunasia amara Blanco) were also common in the ground vegetation of both areas. Percent distribution of trees according to self-defined DBH classes revealed that PTTC had 87.55% of the total recorded plants with DBH measurements of <10 cm. Our data was found lower by almost 10% from TS. Considerable percentages of trees were also shared in other DBH classes for PTTC. DBH class range of 10-20 cm had 6.88%, while 5.58% was computed for DBH class of >20 cm. Percent distribution of trees on these DBH ranges (especially on DBH class >20 cm) indicated the presence of medium and large trees. The largest DBH measured in the PTTC was 70 cm while in TS was only 22 cm. The proposed 10-ha site in Villa Aurora, Bilar, is suited to be utilized as Tarsier Tourism Center. In case the proposed project is to be pursued, enclosure similar to what has been constructed in Canapnapan, Corella, Bohol, Philippines should also be established to prevent stray animals from predating the captive tarsiers.Keywords: floristic inventory, Philippine tarsier, Bohol, primate conservation, tourism. Inventarisasi flora dari Situs Usulan untuk Sentra Wisata Tarsier di Villa Aurora, Bilar, Bohol, FilipinaAbstractPenelitian ini ditujukan untuk melakukan penilaian komposisi vegetasi dari Usulan Lokasi Pusat Wisata Tarsius (ULPWT) di Villa Aurora, Bilar, Bohol dan melakukan analisis perbandingan antara Tarsier Sanctuary (TS) yang ada di Canapnapan, Corella, Bohol. Dasar perbandingan yang digunakan yaitu dengan menghitung nilai penting, kekayaan spesies, dominansi spesies, dan prosentase distribusi dari tumbuhan berdasarkan kelas diameter yang telah ditentukan. Hasil penelitian menunjukkan bahwa kedua tempat memiliki kekayaan spesies dan nilai evenness/ kemerataan yang sangat tinggi. Spesies tumbuhan yang umum ditemukan di overstorey dan understorey di kedua area adalah katagpo (Psychotria sp.), sagimsim (Syzygium brevistylum [C. B. Rob]Merr.), dan bagauak (Clerodendrum minahassae Teijsm. & Binn.). Selain itu, sagimsim (Syzygium brevistylum [C.B.Rob.] Merr.), selaginella (Selaginella cuppresina Lin.), dan lunas (Lunasia amara Blanco) juga umum ditemukan di lantai hutan di kedua tempat. Prosentase distribusi dari tumbuhan berdasarkan kelas diameter yang telah ditentukan menunjukkan bahwa ULPWT memiliki 87.55% dari keseluruhan tumbuhan yang tercatat dengan ukuran diameter <10 cm. Data kami menunjukkan bahwa nilai tersebut lebih rendah 10% dari TS. Sebagian persentase dari pohon juga dimiliki di ULPWT pada kelas diameter lainnya. Kelas diameter 10-20 cm memiliki 6,88%, sementara 5,58% terhitung untuk kelas diameter >20 cm. Prosentase distribusi dari pohon pada kisaran ini (khususnya pada diameter >20 cm) menunjukkan adanya kehadiran pohon berukuran medium dan besar. Diameter terbesar yang terukur di ULPWT adalah 70 cm sementara di TS hanya sebesar 22 cm. Lokasi seluas 10 ha di Villa Aurora, Bilar, sesuai untuk digunakan sebagai Pusat Wisata Tarsius. Apabila akan didirikan, maka kandang yang dibangun diharapkan mirip dengan yang telah dibangun di Canapnapan, Corella, Bohol, Pilipina, agar mencegah pemangsaan oleh satwa yang lepas.

Abstract (sommario):

Wildlife tourism can act as an incentive for the conservation of marine species and habitats. One of the most important outcomes can be a change in the views of participants towards target species and their habitats that may promote more conservation-oriented actions. While a handful of studies have documented the wildlife value orientations (WVOs) of tourists participating in marine wildlife tourism, no studies have explored the WVOs of locals working in tourism. However, it is equally important to understand the WVOs of locals working in community-based tourism, and whether these are linked with changes in locals' attitudes and behaviors towards marine wildlife and the ocean. This article assesses the WVOs of locals working in community-based whale shark tourism at four sites in the Philippines, and explores the relationship between WVOs and conservation attitudes and behaviors using a mixed methods approach with a total of 114 structured interviews. Three WVO groups were identified (mixed utilitarian–protectionist, moderate protectionist, and high protectionist), suggesting a WVO continuum. Those respondents with more protectionist views reported more conservation outcomes, including changes in attitudes and behaviors to protect whale sharks. Further, respondents who worked in tourism had more protectionist views than those from a failed tourism site, indicating that tourism can change communities by helping locals value their marine resources and incentivizing protection of those resources.

Abstract (sommario):

Sea moths (family Pegasidae) are little-studied benthic fish, found throughout the Indo-Pacific. Two species of sea moths, Pegasus volitans and Eurypegasus draconis, are caught incidentally in illegal trawl gear in the Philippines and sold into the dried fish trade. Approximately 130,000–620,000 P. volitans and 130,000 E. draconis were landed off north-western Bohol alone in 1996. An additional 43,000–62,000 sea moths (predominantly P. volitans) were caught live for the aquarium trade. Catch per unit effort for P. volitans was double that of E. draconis, probably because of its occurrence in shallower waters where fishing effort was concentrated. Sea moths may be unsuited for heavy exploitation as they occur at low densities. Moreover, a female-biased catch could lower the effective population size, given the reported monogamy amongst sea moths. No population data were available for a complete conservation assessment, although divers surveyed did report declines in their abundance.

Abstract (sommario):

The Philippines is among the most threatened biodiversity hotspots. Developing effective conservation requires science-based evidence from field data and observations. Yet, many important biodiversity information remain unpublished, particularly from academic institutions and NGOs. Here, we synthesized 34-year data from biodiversity studies from Bicol University in Luzon Island, Philippines. We found a large number of studies that increased in the post-2000 period with the majority of the studies focused on community surveys and animal and wildlife studies. While there is a massive number of studies, we found clear disproportionate distribution in terms of geographic and thematic areas. Our results may be based on a regional level, but if taken carefully, it has important implications and applications to other higher education institutions in the Philippines in promoting biodiversity studies and conservation in the country.

Abstract (sommario):

This study focuses on communities in conservation in central Philippines, with reference to marine protected areas. It analyzes communities as intersections of multiple actors with stratified interests and power, involving complex processes of place-making, ecological knowledge, tenure, governance, markets, and negotiation with domestic and international non-governmental organisations (NGOs). As rights to places are fundamentally at issue with protected areas, matters of tenure are central for the study. And because marine protected areas (MPAs) are community-based, questions of local empowerment have equal centrality.
The ownership of rights to marine resources by village members is a necessary if not sufficient condition for the political empowerment of communities in conservation. The issue of property rights in the Philippines is irrevocably linked to issues of equity, as social actors confront prevailing unequal relations of power. The development of community commitment to the reconfigured arrangements of marine protected area establishment depends on substantial economic gains for marginalized villagers, an equitable distribution of those gain, the ecologically sound management of resources over which rights are negotiated and gains generated, and a socially meaningful realignment of relations of power among nested sources of authority.
My analysis points to the advantages of a reinforced community property regime that would call for measures by the national government to enhance villagers' tenure over their settlements and community waters (katubigang barangay). Such a regime is no panacea for the manifold social and environmental challenges faced by communities, but it would enable them to engage more confidently and constructively with state, NGO and other interests in conservation, and to address the real or perceived threats of dislocation by externally proposed schemes.
Two villages with MPAs in the province of Bohol in central Philippines serve as case study sites to explore intertwined social, economic and political variables that influence issues of conservation, equity and empowerment.

Abstract (sommario):

Biodiversity loss is one of the major environmental threats facing the planet. Incentive-based conservation is one means to reduce human pressure on wildlife by providing economic incentives for resource-dependent people to protect the environment. Marine wildlife tourism is one of the fastest growing tourism sectors globally and is viewed as an important incentive-based approach for achieving marine conservation goals. However, few studies have linked participation in the provisioning of marine wildlife tourism activities with positive social and ecological conservation outcomes. The goal of this dissertation is to provide greater understanding of the conservation value of marine wildlife tourism using whale shark tourism as a case study with a main focus on social conservation outcomes amongst tourism providers. Positive changes in perceptions, attitudes and values towards target species and their environments can be an important element of incentive-based conservation. The study has the following objectives: (1) to assess the status of the global whale shark tourism industry, including types (e.g., captive, non-captive), real and potential impacts, conservation value and management challenges and best practices; (2) to examine the ethics of provisioning whale sharks in Oslob, Philippines, the largest, non-captive viewing site in the world; (3) to determine if working in ecotourism changed the attitudes and behaviours of locals towards whale sharks and the ocean, and if tourism type affects those outcomes; (4) to assess the marine wildlife value orientations of locals working in whale shark tourism to achieve greater understanding of the factors influencing their conservation attitudes and behaviours; (5) to explore the potential long-term impacts of poorly conceived incentive-based conservation projects on social and ecological conservation outcomes; and (6) to re-examine and update the conceptual and theoretical background for wildlife tourism in light of the findings of this study. Methods include a comprehensive literature review, tourist surveys, social media content analysis, and interviews with locals working in whale shark tourism at four sites in the Philippines. Results suggest that marine wildlife tourism can play an important role in changing locals’ attitudes and behaviours towards the focal species and habitat; however, smaller-scale, more established sites had greater conservation value than the mass tourism or failed sites suggesting that small-scale, community-based ecotourism is the best approach to meeting conservation goals of marine wildlife tourism. Yet, few tourism sites meet these standards. Global standards are needed to ensure whale shark tourism activities meet desired conservation goals. Such standards should include management requirements (e.g., licensing, mandatory education program) and interaction guidelines (e.g. minimum viewing distances, limits on the number of swimmers/boats, etc.). The findings also emphasise that economics should not be the only or primary metric used to measure conservation success; rather, the focus should be on assessing a more comprehensive range of social and ecological conservation outcomes of these activities.
