Abstract Females of a number primate species display their fertile period by behavioural and/or morphological changes. Traditionally, the in human females has been considered to be concealed. However, this presumption rarely tested. One possible mechanisms for assessing menstrual cycle phase is through sense smell. In study changes odour across were investigated. Samples body acquired from 12 women (aged 19–27 yr), none whom using hormonal contraceptives. collected cotton pads worn armpit 24...
Social dominance is widely known to facilitate access food resources in many animal species such as deer. However, research has paid little attention ad libitum because it was thought not result any benefit for dominant individuals. In this study we assessed if, even under conditions, social rank may allow hinds consume the preferred components of food. Forty-four red deer (Cervus elaphus) were allowed meal consisting pellets sunflower, lucerne and orange, seeds cereals, corn, cotton, carob...
Hunting dogs are exposed to the risk of injury in driven hunts, an often-used method for managing growing wild boar numbers. This study investigated impact increased hunting pressure-both across season and within individual events-on attacks on dogs, i.e., length (2.68 ± 0.76 months, mean standard deviation), number hunts per (3.99 0.43), intervals between (17.85 4.83 days), boars harvested (14.46 13.10), participants (23.8 10.69) (4.56 2.66) involved hunt. The data were collected via a...
Sex chromosomes differ in their inheritance properties from autosomes, and hence may encode complementary information about past demographic events. We compiled analysed a range-wide resequencing dataset of the red deer (Cervus elaphus), one few Eurasian herbivores Late Pleistocene megafauna still found throughout much its historic range. Our analyses 144 whole genomes reveal striking discrepancies between population clusters suggested by autosomal X-chromosomal data. postulate that genetic...
Melatonin concentrations were measured in serum, luminal fluid, and tissues of the mucosa muscularis entire bovine porcine gastrointestinal tract (GIT). In both species, GIT levels profoundly exceeded serum levels. pigs, melatonin was lowest fluid highest mucosa. No difference found various layers GIT. Compared to cows had higher stomach ileum, but lower cecum colon. There no between anterior posterior segments GIT, whereas pigs exhibited several fold concentration segment (cecum colon)....
The first telemetry study analysing behaviour of the largest freshwater predator in European rivers, Silurus glanis , was performed bimonthly during years 2002–2004. Movement juveniles and adults occurred mostly same time intervals. only statistical differences for nocturnal activity spring autumn. In winter, low with peaks daylight, autumn, maximal movement recorded dusk. summer, catfish were active across whole 24 h even high‐flow conditions. During all other seasons, inversely related to...
The aim of the study was to determine whether cortisol and secretory Immunoglobulin A (sIgA) could be used as an indicator acute stress in both young adult dogs. Seventeen German shepherd puppies were exposed Puppy test (challenge test) at age seven weeks. This has been routinely assess future working ability potential police In addition, ten females subjected 4 minutes defense training under stressful conditions. Saliva collected from before testing 20 after start testing, using a cotton...
An apparatus consisting of 2 silver ring electrodes attached to a plastic rod and connected transistor indicator was used measure electrical impedance changes in the vagina rats. A statistically significant increase occurred at proestrus. By determining when this peak occurs, optimal time for pairing can be established. In paired animals absence provides reliable means diagnosing pregnancy.
Earlier studies have shown variation among experimental attempts to establish whether human monozygotic twins that are genetically identical also individual scents. In none of the cases were dogs able distinguish all scents living in same environment if presented them separately. Ten specially trained police German Shepherd three Czech Republic Police Regional Headquarters used for scent identification our study. The supposed match two pairs (5 and 7 years old) dizygotic twin (8 13 old)....
Animal home ranges typically characterized by their size, shape and a given time interval can be affected many different biotic abiotic factors. However, despite the fact that studies have addressed ranges, our knowledge of factors influencing size area occupied animals is, in cases, still quite poor, especially among raptors. Using radio-telemetry (VHF; 2.1 g tail-mounted tags) we studied movements 20 Tengmalm's owl (Aegolius funereus) males during breeding season mountain Central Europe...
Red deer hinds play a significant role in selecting stags for mating. We tested the hypotheses that red (Cervus elaphus) probability of becoming harem holder (and hence achieving reproductive success) occurs bearing larger, branched antlers and showing low fluctuating asymmetry (FA). Eleven antler characteristics were measured; absolute relative FA calculated on 51 cast sets from 19 individually recognized stags. Probability (PBHH) was originally analysed separately, i.e. size each...
Abstract Fighting between males is a frequent component of the rutting behavior Cervidae. Frequent conflicts are exhausting; fighting may be risky and can lead to serious injuries or even death. We focused on process assessment opponent's ability escalation combat, estimating probability based encounter components such as groaning parallel walk. In this study, we observed agonistic fallow deer bucks ( Dama dama ) during rut over four seasons. During time, recorded 205 encounters bucks....
Fledgling behaviour and movement patterns throughout the post-fledging dependence period (PFDP), especially in relation to changing environmental conditions, have been rarely studied, despite fact that this is recognized as of crucial significance terms high mortality juveniles. The PFDP can extend over quite a protracted period, particularly birds prey, knowledge individuals fundamental for understanding mechanisms underlying survival, habitat use dispersion. We radiotracked 39 fledglings...
At present, many ungulate populations have a complex history of isolation and translocation. Consequently, may experienced substantial reductions the level overall gene flow, yet simultaneously augmented levels long-distance flow. To investigate effect this dual anthropogenic impact on genetic landscape ungulates, we genotyped 35K SNPs in 47 red deer (Cervus elaphus) The Netherlands, including putative autochthonous relic as well allochthonous established private estates rewilding areas. We...
