in this study, by examining the character of the morphometric and meristic in which cyprinion macrostomus samples obtained from different locality in tigris, morphometric character which are transformed subject to discriminant analysis and depending on grouping model to number of discriminant functions and according to importance of these totally variance, morphogical variance among populations...

Members of Nemacheilidae Family, Turcinoemacheilus genus were subjected to molecular phylogenetic analysis in this study. This genus was reported in 2009 to inhabit in Karoon River drainage, in contrary to previous assumption that it was the endemic species in the Basin of Tigris River. It was sampled from three stations placed in different tributaries in Karoon drainage and evaluated to unders...

This paper presents an overall view of major sources that may lead to the pollution of the Tigris within Mosul city. A stretch exceeding 20kms in length is selected that represents the "sick" path of the river. Many sites along the studied stretch are likely to affect the river quality in some way or another. Samples from 40 sources sites are taken for quality analyses These sources--as huge as...

Calliostoma tupinamba isa new species from Southeastern Brazil, ranging from southern Rio de Janeiro to northern São Paulo, and found only on coastal islands, on rocks and sessile invertebrates at 3 to 5 meters of depth. Shell and soft part morphology is described here in detail. Calliostoma tupinamba is mainly characterized by a depressed trochoid shell; eight slightly convex whorls; a sharply...

This study quantified the behavior of 11 tigers during periodic access to an exercise pen throughout the day and night. The study determined the amount of time spent in the pen and the percentage of time spent performing stereotypic pacing, normal locomotor behavior, and lying down while in the pen. Average access to the exercise pen was 10 hr 49 min overnight and 5 hr 30 min during the day. At...

paraschistura ilamensis , new species, is described from the tigris river drainage, iran. it is distinguished from other species of paraschistura in iran by a combination of the following characters: emarginate caudal fin, stout, deep and scaled body, deep caudal peduncle, 7-10 irregular and interrupted vertical pale brown bars on flanks, two obvious dark spots on the upper and lower caudal fin...

Energy budgets for the wide-foraging "arthropodivorous" lizard Cnemidophorus tigris were constructed for the reproductive season using doubly labeled water measurements of field metabolic rate (FMR). Rates of body mass change, clutch sizes, and clutch intervals were also investigated. FMRs of both sexes (males, 298 J g-I d-1; females, 247 J g-I d-1) were greater in the reproductive season than ...
