The Cuban solenodon (Solenodon cubanus) is one of the most enigmatic mammals and is an extremely rare species with a distribution limited to a small part of the island of Cuba. Despite its rarity, in 2012 seven individuals of S. cubanus were captured and sampled successfully for DNA analysis, providing new insights into the evolutionary origin of this species and into the origins of the Caribbean fauna, which remain controversial. We conducted molecular phylogenetic analyses of five nuclear genes (Apob, Atp7a, Bdnf, Brca1 and Rag1; total, 4,602 bp) from 35 species of the mammalian order Eulipotyphla. Based on Bayesian relaxed molecular clock analyses, the family Solenodontidae diverged from other eulipotyphlan in the Paleocene, after the bolide impact on the Yucatan Peninsula, and S. cubanus diverged from the Hispaniolan solenodon (S. paradoxus) in the Early Pliocene. The strikingly recent divergence time estimates suggest that S. cubanus and its ancestral lineage originated via over-water dispersal rather than vicariance events, as had previously been hypothesised.

Asiatic wild cat, Felis silvestris ornata, once regarded as least concern is declining rapidly in its natural habitat in the Xinjiang desert region of China mainly because of excessive hunting for pelt trade followed by shrinkage of its habitat due to cultivation, oil and gas exploration and excessive use of pesticides. Prior to 1950, it was the most abundant felid in Xingjian dwelling along all major river basin systems and Taklimakan desert but later it got confined to three regions of southern Xinjiang only viz., Bayingolin Mongol Autonomous Oblast, Aksu and Hotan. Despite several expeditions, correct distribution and status of this illusive cat was unknown. This review article is an update on current status, distribution, ecological behavior, conservation and habitat characteristics of Asiatic wild cat in Xinjiang arid region of China. Specimen collected from various parts of Xinjiang exhibit varied phenotypic characters. It has protruding morphological features like many other desert animals. It has dense and soft hairs on the forelimb pads like other felids but rarely behaves nocturnally, adjusting its movement with seasonal variation and food availability. Tarim hare, Lepus yarkandensis, is the primary source of food followed by gerbil, jerboa, birds, fish and lizards. Literature and the statistics both reveal that it’s remnant population is declining fast limiting it to only a few fragmented habitats in the lower reaches of Hotan, Yarkand, Tarim, Qarqan, Niya and Keriya river basins, rendering it no more a least concern species at least in China. Therefore, adequate policy decisions and concrete conservation actions are required to halt and eventually reverse the declining population of the cat and its deteriorating habitat in Xinjiang.

Assessing local people's knowledge of endangered species is important not only for the planning and implementation of environmental education programs, but also to address community-based conservation issues and guarantee an effective engagement of local residents in conservation efforts. A questionnaire-based study conducted in Alejandro de Humboldt National Park assessed local people’s knowledge of the endangered Cuban Solenodon (Solenodon cubanus). From this it was found that although children seem to be better informed than adults with respect to the Cuban Solenodon, more needs to be done to educate both age and groups alike. This study also highlighted local residents’ positive disposition to actively participate in the Cuban Solenodon conservation effort.

Phylogenetic analysis was conducted for various populations of the Sorex minutissimus-S. yukonicus complex based on mitochondrial gene (cytochrome b and/or the control region) sequences. Sorex minutissimus was divided into some monophyletic groups in Eurasia; it was divided into 2 main groups, eastern and western Eurasian clades, based on combined data of the cytochrome b and the control region. Monophyly of shrews from Hokkaido-Sakhalin, Primorye, Mongolia-Transbaikalia, southeastern Finland was strongly supported respectively in most analyses. Sorex yukonicus was phylogenetically close to S. minutissimus in eastern Siberia. Some shrews from western and central Siberia were included in the clade of southeastern Finland. Also, most shrews from central-northern Finland and Norway made a clade close to but different from the southeastern Finland clade. This finding suggests that Fennoscandian shrews might consist of individuals which were recolonised from various refugia after the Last Glacial Maximum. Nucleotide diversity of shrews from Hokkaido and Alaska was low. Three regional groups in Kamchatka-Sakha, Sakhalin, and Mongolia-Transbaikalia tended to have medium nucleotide diversity. In contrast, shrews from Cisbaikalia-western Siberia and Fennoscandia had high nucleotide diversity. The S. minutissimus-S. hosonoi group appears to have experienceed a quit different biogeographic history from two shrews with similar ranges, the S. caecutiens-S. hosonoi group and S. tundrensis.
