In this study, a detailed chromosome analysis of the endemic Cappadocian Chub, Squalius cappadocicus in Melendiz Stream (Aksaray) was performed. The standard Giemsa staining, C-banding (CBG and CB-DAPI), Ag-NOR technique were applied. diploid number 50; its karyotype formula 14M + 16Sm 10St 10A. Heteromorphic sex chromosomes weren’t detected studied specimens. all chromosomal arms (NF) 90. C-ba...

In a study of the fishes Lake Hazar, and Tigris, Euphrates Kueik rivers were recorded four species Squalius belonging to Squalis cephalus-group found: The western drainage River (Tohma Stream) population was identified as S. seyhanensis, northern drainages semae, populations berak. comparison 28 metric, 9 meristic parameters morphological characters showed that Hazar upper Tigris are distinct b...

The chub is a freshwater fish of the family Cyprinidae, which is widely distributed throughout Europe. Prior to 2001 there were no reports of chub being present in Ireland. In 2001 and again in 2004 it was reported that an angler had caught chub in a section of the River Inny. On neither occasion were live specimens retained for authentication. In 2005 a number of live, angler-caught chub from ...

A bird-parasitic fly, Carnus orientalis Maa, 1968, is recorded for the first time from Japan, and it is taxonomically reexamined on the basis of specimens collected in Okinawa Prefecture. Adult flies were found from nestlings of Ryukyu scops owl (Otus elegans Cassin, 1852), which is a new host for C. orientalis. Bionomic remarks regarding C. orientalis are presented, and akey to the world speci...

The aim of this paper is to offer some new information on the life and work of Matthias Flacius Illiricus the Younger, especially concerning his activity as a medical doctor and university professor. According to our present knowledge, he published 17 of his writings during his lifetime. Matthias Flacius the Younger was born on September 12, 1547 in Braunschweig. His mother Elisabeth had 11 mor...

There is a critical need to simply and reliably monitor brevetoxins routinely in the blood of humans and aquatic animals. We used striped mullet as laboratory test animals to better define the uptake and elimination kinetics of brevetoxin during an aqueous exposure to the brevetoxin-producing dinoflagellate Karenia brevis. Striped mullet were first exposed to sublethal densities of K. brevis (a...

Patterns of habitat use by fish assemblages in two chalk streams in southern England were examined to identify species preferences with respect to major habitat gradients. Both study sites, although differing in some physical habitat characteristics, mainly channel width, water temperature and instream cover, could be arranged similarly along a continuum extending from erosional to depositional...
