Roe deer (), as a representative of the Cervidae family, are particularly sensitive to negative environmental stimuli due to their need to maintain increased vigilance during feeding. Intensive hunting seasons are undoubtedly also a stressful factor for this species. The aim of this study was to analyze the cortisol levels in the hair of male roe deer collected at the beginning and the end of the hunting season in eastern Poland. In total, hair samples from 26 individuals collected in May and 31 individuals collected in September were analyzed. The concentration of cortisol in the hair was determined using the EIA kit. It was shown that the concentration of cortisol was significantly higher in samples collected in September compared to those collected in May (Pr. > |t| = 0.0017). Moreover, the age of animals and carcass mass did not significantly affect the concentration of the tested hormone. In summary, the concentration of cortisol in the fur of male roe deer depended on the season and was not influenced by the carcass mass or age of the animals studied.

Population density is a valuable metric used to manage wildlife populations. In the Russian Far East, managers use the Formozov- Malyushev-Pereleshin (FMP) snow tracking method to estimate densities of ungulates for hunting management. The FMP also informs Amur tiger () conservation since estimates of prey density and biomass help inform conservation interventions.

This study aimed to investigate the possibility of producing fermented roe deer sausages using acid whey without the addition of sodium nitrite. Additionally, ascorbic acid was added to improve the oxidative stability of the product, and sodium chloride (NaCl) was partially replaced by potassium chloride (KCl) (7:3). The sausages were analyzed after fermentation (on day 30) and during post-production aging (i.

The blastocyst of the European roe deer (Capreolus capreolus) undergoes a period of decelerated growth and limited metabolism. During this period known as embryonic diapause, it floats freely in the uterus encircled by the histotroph. Prior to implantation, reactivation is marked by rapid embryonic growth and conceptus elongation.

Introduction: Due to the Danish fauna, reindeer are not immediately available should Santa Claus need to replace his reindeer while traveling across Denmark with Christmas gifts. Instead, Santa Claus should rely on roe deer, which are predominant in Denmark. However, the population of roe deer may be threatened by collisions between ambulances and roe deer.
