The rate of adaptive evolution, the contribution selection to genetic changes that increase mean fitness, is determined by additive variance in individual relative fitness. To date, there are few robust estimates this parameter for natural populations, and it therefore unclear whether evolution can play a meaningful role short-term population dynamics. We developed applied quantitative methods long-term datasets from 19 wild bird mammal populations found that, while vary between fitness...
The causes and consequences of being in a particular dominance position have been illuminated various animal species, new methods to assess relationships describe the structure hierarchies developed recent years. Most research has focused on same-sex relationships, however, so that intersexual including both sexes remained much less studied. In particular, different continue be employed rank males females along hierarchy, sex biases are still widely regarded as simple byproducts sexual size...
Management strategies to reduce human-carnivore conflict are most effective when accepted by local communities. Previous studies have suggested that the acceptance depends on emotions toward carnivores, cultural importance of and livestock depredation, it may vary depending types carnivores involved. However, no study so far considered these factors simultaneously compare their influence management strategies. We quantified predictive potential three frequently applied mitigate conflict:...
Dispersal is a key driver of ecological and evolutionary processes. Despite substantial efforts to explain the evolution dispersal, we still do not fully understand why individuals same sex species vary in their propensity disperse. The dominant hypothesis emphasizes movements assumes that leaving home (dispersal) staying at (philopatry) are two alternative strategies providing different fitness. It suggests only high phenotypic quality can pursue most beneficial strategy; others left...
Abstract Anthropogenic activity can have substantial effects on wildlife. These may vary according to the characteristics of and species involved. Although behaviour are well studied, studies fitness physiology scarce, particularly for group‐living species. We exploited a natural experimental setup investigate effect diurnal pastoralism juvenile recruitment allostatic load in population free‐ranging spotted hyenas Ngorongoro Crater, Tanzania, over 24‐year period. Pastoralism was restricted...
Abstract In conservation, a growing population is often taken as sign of success. But trends in size can be misleading. When individuals are long-lived, populations may keep growing—for time—even the environment begins to stabilize or deteriorate. Trends carrying capacity ( K ) would better reflect situation that finds itself in, yet commonly assumed static. We developed an individual-based modelling approach estimate time-varying t free-ranging spotted hyenas. noticeably varied due events...
Summary Enzyme immunoassays ( EIA s) are widely used to quantify concentrations of hormone metabolites. Modifications in laboratory conditions may affect the accuracy metabolite concentration measurements and lead misinterpretations when results different combined for a statistical analysis. This issue is great relevance studies behavioural evolutionary ecology because these usually aim at understanding how vary between individuals, environments or experimental conditions. We present method...
Chromosomal change is recognized as an important force in speciation-with-gene-flow models. Although Robertsonian (Rb) translocations contribute to hybrid unfitness and modify recombination patterns, they are generally not considered efficient inversions reducing gene flow. The present study analyses two hybridizing chromosomal races of the house mouse (Mus musculus domesticus), one carrying nine Rb fusions (2n = 22) other ancestral karyotype 40). heterozygosity involves simple meiotic...
Abstract In many animal societies, dominant males have a higher reproductive success than subordinate males. The proximate mechanisms by which social rank influences are poorly understood. One prominent hypothesis posits that rank‐related male attributes of attractiveness and fighting ability the main mediators skew. Yet, empirical evidence in support this is limited. An alternative emphasises inherent dimension dominance relationships relationship between mediated physiological costs...
When and where animals reproduce influences the social, demographic genetic properties of groups populations they live in. We examined extent to which male spotted hyenas (
Abstract The diet of large carnivores is great interest to conservation managers, as it can reveal the extent human-carnivore conflict and impact on species high priority. Metabarcoding environmental DNA identify often more reliable in doing so than observational or morphological methods. particularly powerful at detecting elusive rare has therefore become a widely applied tool biodiversity research. Here, we used metabarcoding fecal samples determine spotted hyenas Ngorongoro Crater,...
