A small, isolated Amur tiger population is living at the southwest Primorskii Krai in Russia and Hunchun in China region. Many of them with "dual nationality" cross the border frequently. Formulating effective conservation strategies requires a clear understanding of tiger food requirements in both Russia and China sides, while Russia side already have clear results of it. We used scat analysis combined with data on the abundance of four prey species to estimate Amur tiger diet and prey preferences in Hunchun...

The generic position of Leuciscus kurui Bogutskaya, 1995 is reviewed through a comparison of morphological and molecular characters (COI). The molecular data place L. kurui in Alburnus, close to Alburnus timarensis from the Lake Van basin. Alburnus kurui (Bogutskaya) is distinguished from this species by lacking a ventral keel and possessing both a very low number of gill rakers and midlateral scales. Alburnus selcuklui, from the upper Tigris drainage, cannot be distinguished from the widespread A. sellal and is therefore treated as a synonym of this species...

Neopilizetes is a genus of the oribatid mite family Galumnidae that was first characterized by having well-developed setae, a dorsosejugal suture, and raised striae on the prodorsum and notogaster. It was proposed to accommodate Pilizetes neotropicus Balogh Mahunka 1978 from Brazil-the only supposed Pilizetes species known outside the Ethiopian Region-and it has remained monotypic. We found adults of N. neotropicus and four related species in soil-litter interface samples of a single cacao plantation in Ilhéus, Bahia, Brazil...

Like fishing, natural regime shifts and human-induced environmental changes are often equally important factors in driving fish stock declines. In the Northwestern Arabian Gulf, many fish stocks are declining, raising questions about the reduction in the flow of Tigris-Euphrates rivers. Here we investigate the relationship between Tigris-Euphrates river flow and the estimated recruitment patterns from assessment models. We found a positive correlation between the estimated finfish recruitment trends and the flow of Tigris-Euphrates rivers...

Mee-Ja M Sula, Linda A Frank, Edward C Ramsay
A striking form of lymphocytic mural folliculitis is described in 6 tigers ( Panthera tigris). Clinically, all tigers exhibited regionally extensive chronic, variably waxing and waning alopecia with minimal scaling and crusting most pronounced over the head, neck, and shoulders. More severely affected tigers exhibited marked hyperpigmentation and lichenification. Pruritus was not a feature. Tigers generally lacked signs of systemic illness and clinical pathology findings were unremarkable. Histologic examination of skin biopsies revealed infiltrative lymphocytic mural folliculitis extending the length of the hair follicle...

With fewer than 200 tigers (Panthera tigris tigris) left in Nepal, that are generally confined to five protected areas across the Terai Arc Landscape, genetic studies are needed to provide crucial information on diversity and connectivity for devising an effective country-wide tiger conservation strategy. As part of the Nepal Tiger Genome Project, we studied landscape change, genetic variation, population structure, and gene flow of tigers across the Terai Arc Landscape by conducting Nepal's first comprehensive and systematic scat-based, non-invasive genetic survey...

A neutered male Siberian tiger ( Panthera tigris altaica) presented with paraplegia of 5 days' duration. Thoracolumbar magnetic resonance imaging (MRI) revealed a focal, linear T2-W hyperintense intramedullary lesion at the level of T10-11 as well as reduced size of the nucleus pulposus of the T10-11 intervertebral disc. The animal was humanely euthanatized as a result of the severity of clinical signs and the poor prognosis. Gross necropsy revealed a dark red, firm focus on the spinal cord at the level of the T11 nerve roots...

A single 8 mg/kg dose of Cefovecin (Convenia®) was administered intramuscularly in the hindlimb of eight anesthetized captive tigers ( Panthera tigris) and serial blood samples were collected over the next 56 days to determine pharmacokinetic characteristics. High-performance liquid chromatography was utilized to determine plasma levels, and demonstrated a mean terminal half-life of 227.8 ± 29.3 hr. Cefovecin, >1 μg/ml, was detected in plasma levels up to 56 days postinjection. Protein binding of tiger plasma for cefovecin was 98%...

Two tiger cubs (Panthera tigris) from the same litter were evaluated for suspected cardiac disease. Two cubs with a dilated cardiomyopathy phenotype were diagnosed with endocardial fibroelastosis based on necropsy and histopathologic examinations. Echocardiography revealed salient anatomic and functional aspects of this cardiac disorder. This is the first report of endocardial fibroelastosis in this species.

The continuing development of improved capture-recapture (CR) modeling techniques used to study apex predators has also limited robust temporal and cross-site analyses due to different methods employed. We develop an approach to standardize older non-spatial CR and newer spatial CR density estimates and examine trends for critically endangered Sumatran tigers (Panthera tigris sumatrae) using a meta-regression of 17 existing densities and new estimates from our own fieldwork. We find that tiger densities were 47% higher in primary versus degraded forests and, unexpectedly, increased 4...

The present study aims to manage and determine the most economical efficiency of five wastewater treatment plants discharging wastewater into the Tigris River in Iraq. The management system was based on ensuring the five-day biological oxygen demand concentration in the river is <30 mg/L according to the Iraqi standards. In many cases, the determined optimized efficiencies were found to be lower than the present working efficiencies. Although this was good for the environment, it was not cost-effective...

The Amur tiger ( Panthera tigris altaica ) is an endangered tiger subspecies. An adult zoo-bred female was found collapsed, and died despite supportive treatment. Hematology and biochemistry showed pancytopenia and hyperglobulinemia, and serum protein electrophoresis revealed a monoclonal band in the β-globulin region. Necropsy demonstrated hemoabdomen, multifocal lytic bone marrow lesions, splenomegaly, and hemorrhagic hepatic nodules, with left medial lobe rupture. There were mutifocal hemorrhages in the subcutis, lung, epicardium, and intestinal mucosa...

Background: Large carnivores influence ecosystem functions at various scales. Thus, their local extinction is not only a species-specific conservation concern, but also reflects on the overall habitat quality and ecosystem value. Species-habitat relationships at fine scale reflect the individuals' ability to procure resources and negotiate intraspecific competition. Such fine scale habitat choices are more pronounced in large carnivores such as tiger ( Panthera tigris ), which exhibits competitive exclusion in habitat and mate selection strategies...

Tigers have lost 93% of their historical range worldwide. India plays a vital role in the conservation of tigers since nearly 60% of all wild tigers are currently found here. However, as protected areas are small (<300 km(2) on average), with only a few individuals in each, many of them may not be independently viable. It is thus important to identify and conserve genetically connected populations, as well as to maintain connectivity within them. We collected samples from wild tigers (Panthera tigris tigris) across India and used genome-wide SNPs to infer genetic connectivity...

In this study, four canine distemper virus (CDV) strains were isolated from captive Siberian tigers (Panthera tigris altaica) and red pandas (Ailurus fulgens) during two separate CDV outbreaks in a zoo in Guangdong province, China. Sequence alignment and phylogenetic analyses based on the full-length hemagglutinin (H) and fusion (F) genes showed that they were closely identical to genotype Asia-1. Prior to confirmation of CDV in Siberian tigers, to control spread of the disease, a live attenuated combination CDV vaccine was used among almost all carnivore animals except for red pandas in which another recombinant combination CDV vaccine was used...
