Stable social structure of spotted hyenas Crocuta crocuta during the dry and wet season in Central Tuli, Botswana

Wildlife Biology, EarlyView.
Group‐living animals often exhibit dynamic social structures, with fission–fusion behavior enabling adaptive responses to environmental changes. Spotted hyenas Crocuta crocuta are large carnivores with complex social dynamics influenced by intrinsic factors, such as rank and kinship, and extrinsic factors, such as prey availability.

Species Identification of Ancient and Medieval Representatives of the Genus Equus based on Genetic Data

Археология евразийских степей
Since one of the peculiarities of the evolutionary history of representatives of the genus Equus (horses, asses and zebras) is the high similarity of the morphology of the skeletons of different species of this genus, morphometric characteristics do not ...

An Adaptive Threshold in Mammalian Neocortical Evolution

, 2013
Expansion of the neocortex is a hallmark of human evolution. However, it remains an open question what adaptive mechanisms facilitated its expansion.

Composition of White Rhinoceros Colostrum and Changes During Early Lactation to Mature Milk

Zoo Biology, EarlyView.
The colostrum phase of white rhinoceros milk ends after 2 days of lactation. The mature milk phase commences after 5 days. The fat content peaks at days 3–4. The Δ9‐desaturase 16 and ‐18 indexes peak at days 2–3. ABSTRACT The proximate composition of milk from seven free‐ranging white rhinoceroses during the first 20 days of lactation is reported with ...

Hyperostotic tympanic bone spicules in domestic and wild animal species [PDF]

, 2016
Hyperostotic tympanic bone spicules (HTBS), or "mucoperiosteal exostoses" (ME, syn.) are small, globular (>= 1 mm in diameter), mostly stalked and drumstick-like, bony structures, which arise from the inner wall of the tympanic bulla and project into the

Can Fecal T3 Metabolite Level Fluctuations in European Roe Deer (Capreolus capreolus) Give Insights on Body Condition and Thermal Stress?

Integrative Zoology, EarlyView.
European roe deer fecal samples were assayed to investigate the potential fluctuations of fecal thyroid hormone metabolites (FTMs) in response to environmental (e.g., the temperature, local densities) and individual (e.g., sex, age, body, and nutritional conditions) variables.

Low plasma cortisol and fecal cortisol metabolite measures as indicators of compromised welfare in domestic horses (Equus caballus)

PLoS ONE, 2017
The hypothalamic-pituitary-adrenal (HPA) axis response to chronic stress is far from straight forward, particularly with regards to animal welfare. There are reports of no effect as well as both decreases and increases in cortisol after chronic stressors.

Validating a Target‐Enrichment Design for Capturing Uniparental Haplotypes in Ancient Domesticated Animals

Molecular Ecology Resources, EarlyView.
ABSTRACT In the last three decades, DNA sequencing of ancient animal osteological assemblages has become an important tool complementing standard archaeozoological approaches to reconstruct the history of animal domestication. However, osteological assemblages of key archaeological contexts are not always available or do not necessarily preserve enough
