The present study reports new records of the distribution of Fiji frogs from extensive geographic sampling on islands where both species were previously reported to persist. Platymantis vitianus is found in populations of varying sizes on six islands (Viwa, Ovalau, Taveuni, Gau, Vanua Levu and Viti Levu). Its congener, P. vitiensis has extant populations on the two largest islands, Viti Levu and Vanua Levu. Based on these recent surveys, our findings suggest that the current IUCN Red List status for P. vitiensis needs to be reclassified from ‘near threatened’ (NT) to ‘vulnerable’ (VU B1b[i]c[ii]). The discovery of a much wider geographic distribution for P. vitianus in recent surveys than recorded in the latter half of the 20th century is encouraging and reveals the need to re-examine known conservation threats. Recommendations for frog conservation in Fiji, with regard to current land-use practices are discussed.

Species records are important for assessing the distribution and status of species over a spatiotemporal scale. Andaman archipelago, off Southeast Asia, is a high avian endemism area, covering an area of >5000 km2. We conducted this survey in 2011 to make an inventory of avifauna of Chalis Ek area. A total of 73 species, belonging to 61 genera and 34 families were recorded, of which 60 were resident, 11 were winter migrants, one vagrant, and a single species introduced from mainland India. Three species were found to be new records, expanding distribution. Thirteen were endemic to the Andaman and Nicobar group of islands and eleven were listed as near threatened in the IUCN Red List. This study shows that sites such as Chalis Ek, even though subject to moderate anthropogenic disturbance, still hosts a large and distinctive avifauna and should be protected.

AbstractThe conservation of wide-ranging, territorial carnivores presents many challenges, not least the inadequacy of many protected areas in providing sufficient space to allow such species to maintain viable populations. As a result populations occurring outside protected areas may be of considerable importance for the conservation of some species, although the significance of these areas is poorly understood. Brown hyaenas Parahyaena brunnea are categorized as Near Threatened on the IUCN Red List and recent research suggests the species may be particularly vulnerable to habitat loss and the conversion of land to agriculture. Here we report on the population density and abundance of brown hyaenas in an area of commercial farmland in western Botswana. Mean brown hyaena density estimated from camera-trap surveys was 2.3 per 100 km2 and from spoor surveys 2.88 per 100 km2, which are comparable to estimates reported for protected areas. Estimated densities were higher on farms used for livestock production than on those used for game farming, suggesting that the species can tolerate land-use change where reliable alternative food resources exist. Our results indicate that populations of brown hyaenas in non-protected areas comprise a significant proportion of the global population and that such areas may be of critical importance for their conservation.

Abstract The giant otter Pteronura brasiliensis, categorized as Endangered on the IUCN Red List, was once widely distributed throughout South America. By the middle of the 20th century the giant otter had become locally extinct along the main rivers of the Orinoco basin. Although some populations seem to have recovered, the paucity of information available does not permit a full evaluation of the species' conservation status. The objective of this study was to estimate the abundance and density of the giant otter population along the Orinoco river in the municipality of Puerto Carreño, Vichada, Colombia, where there is important commercial and recreational fishing. Thirty-nine linear km were surveyed, repeatedly, with a total of 315 km of surveys. Population size was estimated by direct counts of individuals. All individuals detected were photographed and identified individually from their throat pelage patterns. In total, 30 otters were identified, giving a minimum density of 0.77 individuals per km, one of the highest reported for the species in Colombia. Given the high density in this well-developed area, our results highlight the importance of this population for the conservation of the species.

A new species of Justicia (Acanthaceae), J.thailandica, is described and illustrated from Thailand. The new species belongs to Justiciasect.Harnieria and is similar to J.quadrifaria and J.championii, but differs on account of the obviously densely white indumentum in the inflorescence bracts and calyx, ovate leaf blades with margin usually entire, spathulate inflorescence bracts and length ratio of calyx to mature capsule. It is assessed to be “Near threatened” (NE) according to IUCN Red List Category and Criteria. Pollen and seed morphology characters are also reported. Species of Justiciasect.Harnieria in Thailand are discussed and a key to the three recognized species is presented.

Informasi tentang herpetofauna di Punggualas, Taman Nasional Sebangau telah dilakukan pada tahun 2015. Tujuan dari penelitian ini adalah untuk menginventarisasi jenis-jenis herpetofauna setelah empat tahun dari data terakhir di Punggualas, Taman Nasional Sebangau. Metode yang digunakan dalam penelitian ini adalah Visual Encountered Survey (VES) selama empat hari di sepanjang transek Kahiu dan Metarius. Hasil penelitian menunjukkan bahwa terdapat 11 spesies yang terinventarisasi yang terdiri dari delapan spesies reptile (7 famili) dan tiga spesies amfibi (3 famili). Temuan ini lebih sedikit dibandingkan literatur pada tahun 2015 yaitu sebanyak 33 spesies yang terdiri dari 17 spesies reptile (13 famili) dan 16 spesies amfibi (4 famili). Hal ini dikarenakan perbedaan luas daerah pengamatan, lama pengamatan, metode, jumlah orang pengamat, dan tingkat keahlian pengamat. Lima spesies ditemukan pada penelitian ini yang belum ditemukan pada tahun 2015 yaitu Homalopsis buccata, Ahaetulla prasina, Cyrtodactylus sp., Siebenrockiella crassicollis, dan Notochelys platynota. Terkait dengan status, 28 spesies herpetofauna berstatus Least Concern, tiga spesies berstatus Vulnerable, dan satu spesies berstatus Near Threatened. Enam spesies lainnya belum memiliki status konservasi di IUCN Red List. Perlu dilakukan penelitian berikutnya tentang jumlah populasi dan pengamatan pada daerah yang lebih luas.

We describe a new species of Ptychadena from Mutinondo Wilderness in northern Zambia. It has rupicolous tadpoles that develop in a film of water. The species is distinguished on morphology, advertisement call and DNA sequences from other grass frogs and was found to be most closely related to P. broadleyi. It has no contrasting longitudinal bands on the posterior thigh, the foot is longer than half SVL, it has no light triangle on the snout, three phalanges of the fourth toe free of web and the snout has no skin folds. The species should be considered Near Threatened in terms of the IUCN Red List criteria given its limited extent of occurrence and population size.

We present a review of Dendrocephalus (Dendrocephalinus) with an updated diagnosis for the subgenus and a key to all known species. We provide new records of Dendrocephalus alachua, which was previously supposed to be extinct, and we describe a new species, Dendrocephalus proeliator sp. nov., which is separated from all other species based on the form of the male frontal appendage. Dendrocephalus proeliator sp. nov. appears to be morphologically intermediate between D. alachua and D. lithaca. In addition, we provide conservation assessments for all four species in the subgenus, according to IUCN Red List standards. We also report for two species the first known examples of direct male-male agonistic behaviour and competition for access to areas frequented by receptive females.

Twenty-four species representing 21 genera, 16 families and 7 orders of mammals were recorded in the Tripura state, northeast India, from an inventory done from 2006 to 2012. Ten of these species were found in wildlife sanctuaries as well as in primary forests. Four species were recorded exclusively from the wildlife sanctuaries and ten species were recorded only from primary forests. Order Primates was the most diverse group represented by 6 species from 4 genera in 3 families. Frequency sightings data showed that 11 species were rare, 2 species were occasional, one species was frequent, and another 10 species were common. Two species, Large-footed Mouse-eared Bat, Myotis sp., and Greater False Vampire Bat, Megaderma lyra, are new records from the study area.  Overall, 23 of the 24 species recorded are listed in the IUCN Red List, 14 species are listed in CITES, and 14 species are protected under the Indian Wildlife Protection Act, 1972. Threats being faced by many of the recorded mammals from human encroachments are highlighted.
