Abstract
In order to understand the generalist nature of leopards and whether they have any degree of specialization, a study on resource selection of the Indian Leopard (Panthera pardus fusca) was carried out in a tropical dry deciduous forest in Sariska Tiger Reserve, Western India from January 2007 to May 2011 with the use of camera trapping under the mark-recapture framework. Camera trapping was done in an intensive study area (230 km2) encompassing 200 camera locations on 85–130 occasions each year. In total, 40 Indian leopards were identified in the study area, of which seven individual leopards were selected for resource selection analysis. Resource selection by Indian leopards was investigated at two scales. First, habitat selection was studied using compositional analysis comparing habitat availability in the geographic range of all seven Indian leopards and utilization by the individual animals within it. The results showed that habitat selection was non-random (P< 0.001). The leopard’s preference of habitat selection was in the following order: Boswellia forest> Anogeissus forest> Acacia forest> Butea forest> Zizyphus forest> Barren land> Scrubland. Second, resource selection was studied through a generalized linear mixed-effect model (GLMM) comparing the resource availability and utilization in each leopard’s range. The results showed that leopards preferred Anogeissus dominated forest followed by Zizyphus mixed forest and scrubland. In addition, leopards preferred habitat with a higher encounter rate of sambar (Rusa unicolor) and chital (Axis axis) and to a lesser degree of use, habitat with a higher livestock encounter rate. The results revealed that Indian leopards showed a significant degree of preference for moderate to thick vegetation cover and wild prey species rather than areas with open forest types and domestic prey species.

Taxonomic reassessment of Odorrana graminea sensu lato (Anura: Ranidae) in China

Abstract
We sequenced mitochondrial 16S rRNA gene fragments of 84 samples of Odorrana graminea (Boulenger, 1900) sensu lato from 33 sites in southern China. Combining the newly generated sequences and congeneric sequences obtained from GenBank, we reconstructed a molecular phylogeny for the genus Odorrana Fei, Ye and Huang, 1990. Phylogenetic analysis revealed five highly divergent lineages which were paraphyletic within O. graminea sensu lato in southern China. The lineage from Medog and western Yunnan is assigned to O. chloronota (Günther, 1876). The lineage from Hainan, southeastern Guangxi, and southwestern Guangdong corresponds to O. graminea sensu stricto; the lineage from Fujian, Jiangxi, easternmost Guangxi, and northern, central, and eastern Guangdong corresponds to O. leporipes (Werner, 1930); and the remaining two lineages from southern Yunnan represent two cryptic new species. In addition, by checking the type specimens of O. rotodora (Yang and Rao, 2008) we confirmed that O. rotodora is the synonym of O. chloronota.

Contribution to the knowledge of the genus Lytorhynchus Peters, 1863 (Reptilia: Squamata: Colubridae) with special reference to the Iranian taxa

Abstract
The genus Lytorhynchus, spanning from the Sahara’s western fringes to the Middle East, eastern Pakistan, and northwestern India, has seen numerous species and subspecies classifications over the years. Many of these have been deemed synonymous due to overlapping morphological traits, a problem compounded by the absence of a comprehensive phylogenetic study. The taxa residing in Iran exhibit morphological variations attributable to their broad distribution and disjunct populations. Of the seven recognized species, three have been confirmed in Iran, although some populations display pholidosis distinct from initial descriptions. Species identification has also been fraught with ambiguities. This study aims to elucidate the diagnostic characteristics of taxa and furnish an updated identification key by revisiting past studies and examining new voucher specimens. The biogeography of Iranian taxa is also explored.
