APPENDICES – COMMUNITY QUESTIONNAIRE 116 iv PREAMBLE The Climate, Community and Biodiversity Alliance (CCBA) Standards are intended to “foster the development and marketing of projects that deliver credible and significant climate, community and biodiversity benefits in an integrated, sustainable manner. Projects that meet the Standards adopt best practices to deliver robust and credible greenhouse gas reductions while also delivering net positive benefits to local communities and biodiversity”. Validation of a project against these Standards is achieved through a 17-point checklist, comprised of 14 checkpoints compulsory for gaining “Approved” status and an additional 3 optional checkpoints (listed in Appendix 1). Satisfaction of at least one of these optional checkpoints is required to achieve “Gold” status. Many of the checkpoints are either focussed on, or include, aspects of biodiversity. The Orangutan Tropical Peatland Project (OuTrop) was contracted by PT. Rimba Makmur Utama/Starling Resources to help satisfy the checkpoints related to biodiversity and facilitate the acquisition of Approved/Gold Standard status for the proposed Forest Carbon Project in Katingan Regency. Established in 1999, OuTrop is a UK-based group of scientists who carry out research, ecosystem monitoring and conservation management in the peat-swamp forests of the River Sabangau catchment and surrounding areas. Our long-term research focuses are: floral and faunal biodiversity; ecological monitoring; forest ecology, dynamics, phenology and restoration; the distribution, population status, behaviour and ecology of the forest's flagship ape species – the orangutan and agile gibbon – and provide scientific feedback to conservation managers and work with our local partners to implement successful conservation programmes.

Two survey conducted in Ulu Belayan river streams, Mahakam river drainage, District Kembang Janggut, Regency Kutai Timur, Province East Kalimantan. This third survey studied the freshwater fish diversity around Mesangat watershed, District Muara Ancalong, Regency Kutai Kartanegara, Province Kalimantan Timur. There is a quite big swampy area in the District Muara Ancalong, Mesangat swamp or in Bahasa Indonesia we call it Rawa Mesangat. This swamp area is the habitat of the protected species of long snout crocodile, Tomistoma schlegeli. The aim of this survey is to get the information of the fish diversity around Mesangat watershed, the distribution of each site and the status of the species. The results of this survey could be use as the basic data for REA KON to manage the area for the continuation and conservation of the species.

  • BORNEO: Bristleheads, Broadbills, Barbets, Bulbuls, Bee-Eaters, Babblers, and a Whole Lot More
    BORNEO: Bristleheads, Broadbills, Barbets, Bulbuls, Bee-eaters, Babblers, and a whole lot more A Tropical Birding Set Departure July 1-16, 2018 Guide: Ken Behrens All photos by Ken Behrens TOUR SUMMARY Borneo lies in one of the biologically richest areas on Earth – the Asian equivalent of Costa Rica or Ecuador. It holds many widespread Asian birds, plus a diverse set of birds that are restricted to the Sunda region (southern Thailand, peninsular Malaysia, Sumatra, Java, and Borneo), and dozens of its own endemic birds and mammals. For family listing birders, the Bornean Bristlehead, which makes up its own family, and is endemic to the island, is the top target. For most other visitors, Orangutan, the only great ape found in Asia, is the creature that they most want to see. But those two species just hint at the wonders held by this mysterious island, which is rich in bulbuls, babblers, treeshrews, squirrels, kingfishers, hornbills, pittas, and much more. Although there has been rampant environmental destruction on Borneo, mainly due to the creation of oil palm plantations, there are still extensive forested areas left, and the Malaysian state of Sabah, at the northern end of the island, seems to be trying hard to preserve its biological heritage. Ecotourism is a big part of this conservation effort, and Sabah has developed an excellent tourist infrastructure, with comfortable lodges, efficient transport companies, many protected areas, and decent roads and airports. So with good infrastructure, and remarkable biological diversity, including many marquee species like Orangutan, several pittas and a whole Borneo: Bristleheads and Broadbills July 1-16, 2018 range of hornbills, Sabah stands out as one of the most attractive destinations on Earth for a travelling birder or naturalist.

  • Constraints on the Timescale of Animal Evolutionary History
    Palaeontologia Electronica palaeo-electronica.org Constraints on the timescale of animal evolutionary history Michael J. Benton, Philip C.J. Donoghue, Robert J. Asher, Matt Friedman, Thomas J. Near, and Jakob Vinther ABSTRACT Dating the tree of life is a core endeavor in evolutionary biology. Rates of evolution are fundamental to nearly every evolutionary model and process. Rates need dates. There is much debate on the most appropriate and reasonable ways in which to date the tree of life, and recent work has highlighted some confusions and complexities that can be avoided. Whether phylogenetic trees are dated after they have been estab- lished, or as part of the process of tree finding, practitioners need to know which cali- brations to use. We emphasize the importance of identifying crown (not stem) fossils, levels of confidence in their attribution to the crown, current chronostratigraphic preci- sion, the primacy of the host geological formation and asymmetric confidence intervals. Here we present calibrations for 88 key nodes across the phylogeny of animals, rang- ing from the root of Metazoa to the last common ancestor of Homo sapiens. Close attention to detail is constantly required: for example, the classic bird-mammal date (base of crown Amniota) has often been given as 310-315 Ma; the 2014 international time scale indicates a minimum age of 318 Ma.

  • Ancestral Reconstruction of Diet and Fang Condition in the Lamprophiidae: Implications for the Evolution of Venom Systems in Snakes
    Journal of Herpetology, Vol. 55, No. 1, 1–10, 2021 Copyright 2021 Society for the Study of Amphibians and Reptiles Ancestral Reconstruction of Diet and Fang Condition in the Lamprophiidae: Implications for the Evolution of Venom Systems in Snakes 1,2 1 1 HIRAL NAIK, MIMMIE M. KGADITSE, AND GRAHAM J. ALEXANDER 1School of Animal, Plant and Environmental Sciences, University of the Witwatersrand, Johannesburg. PO Wits, 2050, Gauteng, South Africa ABSTRACT.—The Colubroidea includes all venomous and some nonvenomous snakes, many of which have extraordinary dental morphology and functional capabilities. It has been proposed that the ancestral condition of the Colubroidea is venomous with tubular fangs. The venom system includes the production of venomous secretions by labial glands in the mouth and usually includes fangs for effective delivery of venom. Despite significant research on the evolution of the venom system in snakes, limited research exists on the driving forces for different fang and dental morphology at a broader phylogenetic scale. We assessed the patterns of fang and dental condition in the Lamprophiidae, a speciose family of advanced snakes within the Colubroidea, and we related fang and dental condition to diet. The Lamprophiidae is the only snake family that includes front-fanged, rear-fanged, and fangless species. We produced an ancestral reconstruction for the family and investigated the pattern of diet and fangs within the clade. We concluded that the ancestral lamprophiid was most likely rear-fanged and that the shift in dental morphology was associated with changes in diet. This pattern indicates that fang loss, and probably venom loss, has occurred multiple times within the Lamprophiidae.

And this was suggested as one of the earliest records for fossil cyprinids. Unfortunately, this specimen is poorly preserved and reveals no more morphological information than its serrated last unbranched dorsal and anal fin rays. Recently, some new specimens were unearthed from the same locality, where C. maomingensis was discovered. In addition to the serrated dorsal and anal fin rays, these new materials also show that the pattern and shape of their pharyngeal teeth obviously differ from that of Cyprinus but resemble that of Procypris. However, its number of the branched dorsal fin rays and number of vertebrae are much less than that in Procypris.

These exempted items will will be acted upon individually. We will also act individually on items exempted by the Executive Committee. Please remember to bring this booklet with you to the meeting. I will bring a few extra copies to Portland. Please contact me directly (email is best - [email protected]) with any questions you may have. Please notify me if you will not be able to attend the meeting so I can share your regrets with the Governors. I will leave for Portland (via Davis, CA)on 18 July 2008 so try to contact me before that date if possible. I will arrive in Portland late on the afternoon of 20 July 2008. The Annual Business Meeting will be held on Sunday 26 July 2009 from 1800-2000 h in Galleria North.

  • Reptiles of Phetchaburi Province, Western Thailand: a List of Species, with Natural History Notes, and a Discussion on the Biogeography at the Isthmus of Kra

On the basis of a review of available literature, original field observations and examination of museum collections, a preliminary list of 81 species (12 chelonians, 2 crocodiles, 23 lizards, and 44 snakes) is established, of which 52 (64 %) are reported from the province for the first time. The possible presence of additional species is discussed. Some biological data on the new specimens are provided including some range extensions and new size records. The herpetofauna of Phetchaburi shows strong Sundaic affinities, with about 88 % of the recorded species being also found south of the Isthmus of Kra. A biogeographic affinity analysis suggests that the Isthmus of Kra plays the role of a biogeographic filter, due both to the repeated changes in climate during the Quaternary and to the current increase of the dry season duration along the peninsula from south to north.
