BACKGROUND Invasive species are a serious problem in ecosystems, but are difficult to eradicate once established. Predictive methods can be key in determining which areas are of concern regarding invasion by such species to prevent establishment [1]. We assessed the geographic potential of four Eurasian cyprinid fishes (common carp, tench, grass carp, black carp) as invaders in North America vi...

this study was conducted to determine length-weight and length-length relationships, relative condition factor (krel) and fulton?s condition factor (k) for five species including scardinius erythrophtalmus, carassius auratus gibelio, cyprinus carpio, tinca tinca and hemiculter leucisculus belonging to cyprinidae family. fish sampling was carried out by gill net and fyke net in the western regio...

Monozoic cestodes of the genus Khawia Hsü, 1935 (Caryophyllidea: Lytocestidae), parasites of cyprinid fish in Europe, Asia, Africa and North America, are revised on the basis of taxonomic evaluation of extensive materials, including recently collected specimens of most species. This evaluation has made it possible to critically assess the validity of all 17 nominal species of the genus and to p...

Yeniçağa Gölü Kuzey Anadolu fay hattı kuşağının etkisiyle oluşmuş bir çukurluğun sonradan alüvyonlarla dolması sonucu meydana gelmiştir. gölü derinliği 2 metreyi bulan Türkiye’nin en büyük turbalığını içermektedir. aynı zamanda ticari balıkçılık potansiyeli olan doğal su kaynağıdır. Gölde bugüne kadar yapılmış araştırmalarda toplam altı balık türü tespit edilmiştir. Bunlar, Cyprinidae familyası...

The thesis ‘Genetics of Attention and Executive Functioning’ examined the genetic architecture of attention problems, attention, executive functioning, and intelligence (IQ). In addition, the (longitudinal) genetic relation among attention problems, executive functioning and IQ were investigated. Data were collected twice in a sample of twin children registered at the Netherlands Twin Registry ...

There is growing evidence that Enterobacteriaceae harboring clinically relevant bla genes, especially genes encoding the CTX-M family of extended-spectrum -lactamases (ESBLs), have spread into the environment (1). The purposes of this study were (i) to investigate the occurrence of expanded-spectrum-cephalosporinresistant Enterobacteriaceae in intestines of fish captured from Lake Zürich and La...
