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 necessary to identify its suitable habitats and factors affecting... More

Abstract: This study aims to determine the morphometric characteristics and reproductive performance of Pasundan cows which are extensively reared on smallholder farms in the coastal areas of the south (Garut, Cianjur, and Sukabumi) and North Priangan (Bogor, Purwakarta, and Sumedang). This research is descriptive research with a qualitative approach. Production characterization was carried out using a simple method, namely by measuring the body surface... 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,... More

Abstract: In order to explore the influence of the polymorphism in the 20intron region of the Sansui duck ATP2A2 gene on the eggshell quality, this study used Primer Premier 5 software to design and synthesize a pair of primers in the 20 intron region, two-way direct sequencing and sequence alignment to mine SNPs Sites, SPSS 18.0 software was used to analyze the relationship between SNP sites and eggshell quality of Sansui duck.Three SNP sites were found...

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... More
