There are large differences in sensitivity to the toxic and biochemical effects of dioxins and dioxin-like compounds (DLCs) among vertebrates. Previously, we demonstrated that the difference in sensitivity between domestic chicken (Gallus gallus domesticus) and common tern (Sterna hirundo) to aryl hydrocarbon receptor 1 (AHR1)-dependent changes in gene expression following exposure to 2,3,7,8-t...
The aim of this research is to characterise the wild rabbit (Oryctolagus cuniculus) commercial game farms in Spain using variables related to structure, management and marketing. To this end, a structured survey was administered in 2009 to 21 privately-owned farms. This subsector was an average age of 13. The average size of the breeding stock of the farms was 431 does and 64 bucks. Eighty-five...
Willow ptarmigan (Lagopus lagopus lagopus) were censused in late summer for 4 years and broods classified as first, renest, or null (empty) broods. From brood frequencies and clutch size data, estimates were made of egg production, hatching success, survival of young, and contribution to production of each class. Loss of first clutches (N = 231) averaged 27%, and renesting compensated for 43% o...
One of the possible reasons for pheasant population number decline in past several years might be loss of adaptability in populations originated from breeding stations caused by inbreeding depression. Due to fact that adaptability is a consequence of genetic structure of the populations, the aim of this paper was the analysis of genetic variability in pheasant population from breeding station R...
