Reducing the dependency of fishfeed for marine ingredients and species diversification are both considered crucial factors sustainable development aquaculture. The substitution fish oil (FO) by vegetable oils (VO) in aquafeeds is an economically feasible solution. However, such may compromise flesh content essential n-3 long chain polyunsaturated fatty acids (n-3 LC-PUFA) and, therefore, its nu...

The eastern grey squirrel (Sciurus carolinensis) is a North American tree species which has been introduced to several countries outside its native range. We made use of squirrels culled in Italy within control activities establish hematological reference intervals for this invasive species, with the aim broaden current knowledge about physiology. Blood from 104 individuals was analysed through...

despite its largest range of distribution in comparison to other large carnivores in iran, the grey wolf has been the least-studied carnivore in the country with limited available data on its ecology. its social life and population composition have been investigated across its global range in europe and north america; however, it has been less explored in arid environments of asia. accordingly,...

The aim of this study was to evaluate the use of gonadal alterations in the thinlip grey mullet (Liza ramada) as a biological indicator in assessing aquatic ecosystems health, with particular emphasis to river ecosystems exposed to sewage discharges. For this purpose, the reproductive status and the presence of gonadal alterations were studied in 206 mullets collected from two sites on the low ...

The grey hamster has been used in biomedical research for decades. However, effective molecular methods for evaluating the genetic structure of this species are lacking, which hinders its wider usage. In this study, we employed cross-amplification of microsatellite loci of species within the same genus by polymerase chain reaction. Loci screened included 107 from the Mongolian gerbil (MG) and 6...
