Abstract:
Cervids show a high degree of abnormalities in their sperm cells. Thus, this study aimed to select high-quality spermatozoa using magnetic-activated sperm sorting (MASS) compared to density gradient centrifugation (DGC) by assessing the post-selection cell quality. Semen from six Mazama deer was collected by electroejaculation after chemical restraint. The semen was analyzed in four samples: Fresh, DGC, SEMgood - non-apoptotic fraction,and SEMpoor... More

Abstract:
This article considers the natural regulators of blood-sucking Simuliidae subzone of mixed forests on the territory of Belarus and Ukraine. In the mixed forests, the major regulators of preimaginal phases of bloodsucking blackflies are microsporidia (Polidyspirenia simulii,Polidyspirenia sp., Thelohania fibrata, Amblyospora bracteata, A. varians), fungi and mermithides (Gastromermis boophthorae). Caddisfly larvae (Hydropsyche angustipennis, Neureclipsis... More

Abstract:
Identifying suitable habitats of species is essential knowledge to conserve them successfully. Human activities cause the reduction of population size and habitat suitability of many species. Red-backed Shrike is widespread in western Palearctic. However, the population of this specie has declined in its geographical range due to the loss of suitable habitats. Therefore, it is... More
