Invasive species can cause substantial ecological impacts on native biodiversity. While ecological theory attempts to explain the processes involved in the trophic integration of invaders into native food webs and their competitive impacts on resident species, results are equivocal.

The effects of methionine supplementation in diets with different replacement levels fish meal (FM) by pea protein concentrate (PPC) on survival, growth performance and body composition juvenile tench (0.39 g initial weight) were studied a 90-day experiment. Six practical (50% crude protein) differing level FM PPC tested: 0% (control diet), 35%,45%, 60%, 75% or 85%, corresponding to 0, 285, 366...

The Boojagh international wetland with a surface area of 80 hectares and 25 fish species is located in the southwest shores of the Caspian Sea (Guilan province, Iran), but there is no report about fish parasites in this wetland. In the present study, a total of 553 individuals of 8 fish species including Cyprinus carpio (n=71), Abramis bjoerkna (n=153), Carassius auratus gibelio (n=89), Esox...

The writing skills of undergraduate Information Technology (IT) students concern many educators (Utley, 1998, cited in Tench, 2001). This paper examines the relationship between students' business writing results and their technical computing papers results. Some unexpected findings are presented highlighting the need for the inclusion of a writing paper in an IT degree.

The concentrations of heavy metals (Ag, Cd, Co, Cu, Ni, Pb, Zn) were analyzed in muscle, skin and liver of Anatolian Khramulya, Capoeta tinca (Heckel, 1843) from Çamlıgöze Dam Lake located at Central Anatolian region of Turkey. The heavy metal analysis of samples was carried out by using a flame atomic absorption spectrophotometer. Ag, Cd, Co, Pb and Zn were found in all of the examined tissues...
