the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Unexpected population genetic structure of European roe deer in Poland: an invasion of the mtDNA genome from Siberian roe deer.
Introgressive hybridization is a widespread evolutionary phenomenon which may lead to increased allelic variation at selective neutral loci and to transfer of fitness-related traits to introgressed lineages. We inferred the population genetic structure of the European roe deer (Capreolus capreolus) in Poland from mitochondrial (CR and cyt b) and sex-linked markers (ZFX, SRY, DBY4 and DBY8). Ana...
متن کاملControl of red deer (Cervus elaphus) stag domination in rut season by estrus synchronization
BACKGROUND: Inbreeding is one of the major problems of small size herds of red deer in refuge wildlife parks. OBJECTIVES: The aim of the present study was to use estrus synchronization technique in red deer (Cervus elaphus) based on natural mating to control the dominancy and social rank of stags and inbreeding. METHODS: In this study, hinds (n=6) were captured and caged at breeding season (ear...
متن کاملPopulation density and sex do not influence fine-scale natal dispersal in roe deer.
It is commonly assumed that the propensity to disperse and the dispersal distance of mammals should increase with increasing density and be greater among males than among females. However, most empirical evidence, especially on large mammals, has focused on highly polygynous and dimorphic species displaying female-defence mating tactics. We tested these predictions on roe deer, a weakly polygyn...
متن کاملHigh Juvenile Mortality Is Associated with Sex-Specific Adult Survival and Lifespan in Wild Roe Deer
Male mammals typically have shorter lifespans than females [1]. Sex differences in survival may result, in part, from sex-specific optima in investment in reproduction, with higher male mortality rates from sexual competition selecting for a "live-fast die-young" strategy in this sex [2]. In the wild, lifespan is also influenced by environmental conditions experienced early in life. Poor condit...
