The taxonomic status of Thamnurgus rossicus was evaluated with respect to the morphologically similar T. petzi using genetic markers. Nucleotide data from the mitochondrial COI gene revealed 2.4% variation between the European Alps and Russian steppe populations. The two nuclear DNA markers CAD and EF1á were identical across populations. In view of their similar morphology, genetic composition,...

Size structure data particularly that of length and weight is very important fisheries management tool, which is also applied to assess the health, habitat and integrity of the rivers. Nepal is tremendously rich in both fisheries and water resource and thus, this analysis is very important. However, this kind of analysis is not common in fisheries studies and hence the size structure informatio...

A new species of short brown unpatterned moray eel of the genus Gymnothorax, Gymnothorax mishrai sp. nov. is described from a specimen of 324 mm total length, collected from the Bay of Bengal. The species is distinguished by having the dorsal-fin origin before gill opening, jaw pores with brown rim, two branchial pores, total vertebrae 134 (MVF: 9-59-134), three median intermaxillary teeth, uni...

the current status and distribution of the dragonflies (anisoptera) of pakistan were studied during 2005-2009. two dragonfly species were identified for the first time from pakistan. among these, rhodothemis rufa is a red, medium-sized dragonfly. lamelligomphus biforceps is also reported for the first time from pakistan and re-described owing to having minor taxonomic differences from that of f...

This study was carried out between November 2013 and May 2015, to determine the fish fauna inhabited in Atatürk Dam lake. The specimens were obtained by different technical fishing gears. It determined that caught belonging 25 species (Capoeta trutta, Capoeta umbla, Cyprinon macrostomus, Arabibarbus grypus, Carasobarbus luteus, Carassius carassius, gibelio, Cyprinus carpio, Garra variabilis, Lu...

Previous studies of population genetic structure in Dissostichus eleginoides have shown that oceanographic and geographic discontinuities drive in this species population differentiation. Studies have focused on the genetics of D. eleginoides in the Southern Ocean; however, there is little knowledge of their genetic variation along the South American continental shelf. In this study, we used a ...
