Characteristics of Dens of Brown Bear Ursus arctos Linnaeus, 1758 (Carnivora: Ursidae) in Bulgaria
Acta zoologica Bulgarica, 2023 The hibernation is a critical period for the survival and reproduction of the brown bear. By this reason, the knowledge of the dens’ location and characteristics is crucial for planning management actions to reduce disturbance in these areas. In order to

Integrative Zoology, EarlyView.We decode mitochondrial genomes across all extant canids, revealing lineage‐specific codon optimization driven by altitude, predation, and body size. A tripartite framework integrates geological events, metabolic constraints, and adaptive radiation to explain carnivore evolution.

Hibernating bears (Ursidae): metabolic magicians of definite interest for the nephrologist [PDF]
Kidney International, 2013 Muscle loss, osteoporosis, and vascular disease are common in subjects with reduced renal function. Despite intensive research of the underlying risk factors and mechanisms driving these phenotypes, we still lack effective treatment strategies for this underserved patient group. Thus, new approaches are needed to identify effective treatments.

Geographic distributions shape the functional traits in a large mammalian family
Ecology and Evolution, 2021 Traits of organisms are shaped by their living environments and also determined in part by their phylogenetic relationships. For example, phylogenetic relationships often affect the geographic distributions of animals and cause variation in their living ...

Journal of Anatomy, EarlyView.This paper histologically analyzed incremental markings in dental enamel of red fox and grey wolf. Our results demonstrate that previous studies have misidentified these markings, which led to miscalculation of dental growth parameters. Abstract The present study analyzed incremental markings in the enamel of eight mandibular first molars (M1) of red ...

Occurrence and structure of epipharyngeal pouches in bears (Ursidae)
Journal of Anatomy, 2001 The infrequent mention of epipharyngeal pouches occurring in some species of bears indicates the scarcity of morphological and functional knowledge about these structures. In order to provide precise morphological data on the structure of these remarkable formations and to verify their taxonomic utility, the pharyngeal regions of 1 spectacled bear and ...
