| [new evidence for the spread of thelazia callipaeda in the far east]. | thelazia callipaeda nematodes parasitize in the eyes of domestic and wild carnivorous mammals (more often in canidae). numerous cases of human infestation are also known. the nematode spreads in south and east asia although in the last decade this has been reported from dogs, cats and wolves in south and central europe as well. in the russian federation, t. callipaeda was earlier observed in dogs, cats, foxes and raccoon dogs in some regions of the russian far east. two cases of human infestatio ... | 2015 | 25850318 |
| canine distemper virus: an emerging disease in wild endangered amur tigers (panthera tigris altaica). | fewer than 500 amur tigers (panthera tigris altaica) remain in the wild. due to low numbers and their solitary and reclusive nature, tiger sightings across their range in the russian far east and china are rare; sightings of sick tigers are rarer still. serious neurologic disease observed in several wild tigers since 2001 suggested disease emergence in this endangered species. to investigate this possibility, histology, immunohistochemistry (ihc), in situ hybridization (ish), and reverse transcr ... | 2013 | 23943758 |
| identifying ecological corridors for amur tigers (panthera tigris altaica) and amur leopards (panthera pardus orientalis). | the rapid explosion of human populations and the associated development of human-dominated landscapes have drastically reduced and fragmented habitat for tigers (panthera tigris) and leopards (panthera pardus) across asia, resulting in multiple small populations. however, amur tiger (panthera tigris altaica) habitat in russia has remained largely interconnected, except for a break between tigers in southwest primorye and the southern sikhote-alin mountains. this habitat patch in southwest primor ... | 2015 | 26096589 |
| conservation genetics of the far eastern leopard (panthera pardus orientalis). | the far eastern or amur leopard (panthera pardus orientalis) survives today as a tiny relict population of 25-40 individuals in the russian far east. the population descends from a 19th-century northeastern asian subspecies whose range extended over southeastern russia, the korean peninsula, and northeastern china. a molecular genetic survey of nuclear microsatellite and mitochondrial dna (mtdna) sequence variation validates subspecies distinctiveness but also reveals a markedly reduced level of ... | 2008 | 12547918 |
| social structure and space use of amur tigers (panthera tigris altaica) in southern russian far east based on gps telemetry data. | to better understand the spatial structure of amur tigers (panthera tigris altaica) at the southern edge of their range we fitted 14 tigers (6♀♀ and 8♂♂) with 15 gps-argos collars between 2008 and 2011 in 2 study sites: the ussuriskii reserve of southern sikhote-alin and the land of the leopard national park in southwest primorye, russian far east. fixed kernel estimates of male home ranges were larger than those of female home ranges (p < 0.05 [mean 95% fixed kernel(♀) = 401 ± 205 km(2) ; mean ... | 2015 | 26037451 |
| applying molecular genetic tools to the conservation and action plan for the critically endangered far eastern leopard (panthera pardus orientalis). | a role for molecular genetic approaches in conservation of endangered taxa is now commonly recognized. because conservation genetic analyses provide essential insights on taxonomic status, recent evolutionary history and current health of endangered taxa, they are considered in nearly all conservation programs. genetic analyses of the critically endangered far eastern, or amur leopard, panthera pardus orientalis, have been done recently to address all of these questions and develop strategies fo ... | 2003 | 14558456 |
