The importance of farmland for the conservation of the brown hyaena Parahyaena brunnea

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.

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.

Study Species

In terms of conservation, Argentinian odonates have not been assessed using a quantitative approach. One way to achieve this is by modelling their distribution to gather the extent of occurrence. Thus, we modelled the current and future (projected year, 2050) potential distribution of 44 odonate species that occur in Argentina as well as in neighboring countries. Our models of current times indicate a fairly wide distribution for most species but one exception is relevant for conservation purposes: Lestes dichrostigma has less than 30,000 km2 and falls in the ‘Near Threatened’ category according to the IUCN Red List. Another seven species have less than or close to 100,000 km2: Elasmothemis cannacrioides, Erythemis credula, E. paraguayensis, Heteragrion angustipenne, H. inca, Lestes forficula, and Mecistogaster linearis. Future distribution estimates suggest that: a) 12 species will lose or gain around 10%, four species will increase their distribution beyond 10% (up to 2,346%), and 28 species will lose more than 10% (up to 99%). Although current protected areas embrace most odonate species in Argentina, it is still premature to conclude whether this situation will remain in the future given the physiological tolerance and dispersal abilities of the study species among other drivers of distribution.

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.

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.

AbstractAders’ duiker Cephalophus adersi is a small antelope endemic to the coastal forests of east Africa. Threatened by habitat loss and hunting, the species is categorized as Critically Endangered on the IUCN Red List. Until recently Aders’ duiker was known to persist only on Zanzibar, Tanzania, and in the Arabuko-Sokoke Forest National Reserve, Kenya. However, in 2004 a sighting of a single individual was reported from the Dodori forest in northern coastal Kenya, raising the possibility that the species survives elsewhere. Subsequently, an opportunistic camera-trap survey was conducted in September and October 2008 to establish the occurrence of Aders’ duiker in Kenyan coastal forests north of the Tana River. One hundred and fifty six images of Aders’ duikers were obtained from 12 of 28 camera-trap sites (46 of 358 camera-trap days), confirming the existence of a population of Aders’ duiker in the Boni–Dodori forest both inside and outside the National Reserves. In addition, we sighted individuals of the species on three occasions. The relatively high encounter rates per unit effort compared to similar data from Arabuko-Sokoke forest suggest the Boni–Dodori population is significant. Initial surveys of the local Awer community revealed that Aders’ duiker is well known by the name guno. These findings significantly improve the conservation prospects for Aders’ duiker and highlight the need for greater research and management efforts in the poorly known Boni–Dodori forest.

AbstractThreat analyses of the Boraginales were conducted and used to assess the effectiveness of Madagascar’s current and proposed protected area systems in conserving the threatened species of a group of plants widespread in Madagascar. Specimen locality data for 52 species of four families of Boraginales were analysed to provisionally assign species to IUCN Red List categories. Six species were excluded from these global analyses as they are non-native and introduced. IUCN’s criterion B, analysis of geographical range, was found to be the most reliable means of estimating threat, and predicted future decline was found to overestimate threat. Twenty-six of the 46 native species of Boraginales were found to be threatened. Sixty-five percent of these have portions of their ranges in the 2002 protected areas system. When the protected areas system was expanded in 2006 the percentage of species with some protected populations increased to 78%. More than 93% would be protected if a series of proposed priority areas for plant conservation were protected. The implications of these analyses for the conservation of plant species in Madagascar are discussed.
