“…Small coffee, cacao, livestock areas and small human settlements within the Gallon Jug Estate boundaries facilitate a degree of disturbance; therefore, we suspect that this may partially explain high ocelot detections. Like other small‐ and medium‐sized felids, ocelots are generalists and likely prey heavily on small rodents (Grassman et al , de Oliveira et al , Bashir et al ) and may benefit from agricultural production areas, which offer a rich food supply to rodents and other small‐mammal populations (Schmid‐Holmes and Drickamer ).…”

Ocelots (Leopardus pardalis) are listed as least concern on the International Union for Conservation of Nature (IUCN) Red list of Threatened Species, yet we lack knowledge on basic demographic parameters across much of the ocelot's geographic range, including population density. We used camera-trapping methodology and spatially explicit capture-recapture (SECR) models with sex-specific detection function parameters to estimate ocelot densities across 7 field sites over 1 to 12 years (from data collected during [2002][2003][2004][2005][2006][2007][2008][2009][2010][2011][2012][2013][2014][2015] in Belize, Central America. Ocelot densities in the broadleaf rainforest sites ranged between 7.2 and 22.7 ocelots/100 km 2 , whereas density in the pine (Pinus spp.) forest site was 0.9 ocelots/100 km 2 . Applying an inverse-variance weighted average over all years for each broadleaf site increased precision and resulted in average density ranging from 8.5 to 13.0 ocelots/100 km 2 . Males often had larger movement parameter estimates and higher detection probabilities at their activity centers than females. In most years, the sex ratio was not significantly different from 50:50, but the pooled sex ratio estimated using an inverse weighted average over all years indicated a female bias in 1 site, and a male bias in another. We did not detect any population trends as density estimates remained relatively constant over time; however, the power to detect such trends was generally low. Our SECR density estimates were lower but more precise than previous estimates and indicated population stability for ocelots in Belize. Ó

Closely related species show species-specific environmental responses and different spatial conservation needs: Prionailurus cats in the Indian subcontinent

Phylogenetically closely related species are often assumed to have similar responses to environmental conditions, but species-specific responses have also been described. These two scenarios may have different conservation implications. We tested these two hypotheses for Prionailurus cats (P. rubiginosus, P. bengalensis, P. viverrinus) in the Indian subcontinent and show its implications on species current protected area coverage and climatic suitability trends through time. We fitted ecological niche models with current environmental conditions and calculated niche overlap. In addition, we developed a model for the Jungle Cat Felis chaus to compare species responses and niche overlap estimates within Prionailurus with those for a related sympatric small cat species. Then we estimated the proportion of current suitable environment covered by protected area and projected climatic models from past (last interglacial) to future (2070; RCP4.5 and RCP8.5) conditions to show implications on population management and conservation. The hypothesis of a similar response and niche overlap among closely related species is not supported. Protected area coverage was lowest for P. viverrinus (mean = 0.071, SD = 0.012) and highest for P. bengalensis (mean = 0.088, SD = 0.006). In addition, the proportion of the subcontinent with suitable climate varied through time and was species-specific. For P. bengalensis, climatic suitability shrunk since at least the mid-Holocene, a trend that can be intensified by human-induced climate warming. Concerning P. viverrinus, most predictions show stable future climatic suitability, but a few indicated potential loss. Climatic suitability for P. rubiginous was predicted to remain stable but the species exhibited a negative association with intensive agriculture. Similar responses to environmental change by phylogenetically closely related species should not be assumed and have implications on protected area coverage and natural trends of species climatic suitability over time. This should be taken into account during conservation and management actions.

Abstract. The Terai-Arc Landscape in the foothills of Himalaya supports a mosaic of wildlife habitats that sustains an amazing biodiversity. The high human pressure coupled with developmental activities, not only degrade wildlife habitats but restrict the dispersal of wild animals particularly in multiple-use managed forest. We determined the status of wildlife habitats in Ramnagar Forest Division classifying Landsat 8 OLI/TIRS image acquired on April 2015. Landsat Aster GDEM data of 17 October 2011 was used to assess slope, aspect and elevation of the study area. Sal forest was the dominant class and it was followed by sal mixed forest, mixed forest, human habitation and barren land. The elevation ranges between 307m and 1892m amsl with sizable area having gentle slope (5 0 to 10 0 ). Most of the region was south facing. Importance of these habitats for mammals of western Terai-Arc Landscape has been discussed. The current information is expected to serve as baseline information for planning future management strategies and determining changes in wildlife habitats.
