Most mammals rely upon scent for intraspecific communication. As most bear species have large home ranges and are non-territorial, deposit while walking could be an effective way to communicate with conspecifics. Here, we investigate the existence of pedal glands in brown bears their role chemical communication from a histological, biochemical behavioural perspective. We found eccrine footpads, prominent apocrine sebaceous interdigital, metacarpal metatarsal skin sections. Pedal contained 26...
Abstract We analysed the differentiation of body cover in grass snake ( Natrix natrix L.) over full length embryo's at each developmental stage. Based on investigations using both light and scanning electron microscopes, we divided embryonic development integument into four phases. The shape epidermal cells changes first caudal ventral parts embryo, then gradually towards rostral dorsal areas. In stage V side embryo gastrosteges are formed from single primordia, but epidermis forms scale...
In this study, we aimed to provide a neuroanatomy atlas derived from cross-sectional and magnetic resonance imaging (MRI) of the encephalon brown bear (Ursus arctos). A postmortem brain analysis using (MRI - 1,5T; high-resolution submillimeter three-dimensional T1-3D FFE) macroscopic anatomy methods revealed major embryological anatomical subdivisions encephalon, including ventricular system. Most internal structures were comparably identifiable in both methods. The tractus olfactorius...
Sexually stimulating behaviors that are not linked to reproduction rare among non‐human (especially non‐primate) mammals. Such may have a function in the hierarchy of social species. In solitary species, such more enigmatic, and possibly indicative something abnormal. Here, we report on case two male brown bears, raised captivity since being orphaned as cubs, which engaged recurrent fellatio multiple times per day until at least 10 years old. The roles provider receiver act remained...
The welfare of captive bears became a big issue concern in Poland when case bear being ill-treated high-profile the media. This created challenge to verify, study, and understand main problems associated with keeping so that zoos could significantly improve conditions which they keep or ensure at minimum required standards. results presented here are from 1 few countrywide studies conducted all institutions bears. Thirteen kept time study (2007–2009), including 54 individuals 5 species....
This study investigated a chromosome hybrid zone between two chromosomal races of the common shrew (Sorex araneus). Gene flow and genetic structure zone, located in northeast Poland, were studied using seven polymorphic autosomal microsatellite loci (L9, L14, L33, L45, L67, L68, L97) Y-linked locus (L8Y). Seventy-five animals (46 Łęgucki Młyn race 29 Popielno race) from nine different localities examined data analyzed hierarchical AMOVA F-statistic. The (divided into geographical...
The alpine bullhead (Cottus poecilopus) in Poland is highly polymorphic (P for examined populations the range of 0.0–0.45, mean P = 0.11, species 0.64) seven out 11 loci studied (Pgd-1, Mdh-1, Ck-1, Gpd-1, Gpd-2, Gpi-1, Gpi-2). However, they reveal very low heterozygosity (mean Ho 0.007, He 0.019), which may result from population subdivisions, small genetically effective size (Ne) some and frequent inbreeding, latter being probably mediated through polygyny. index genetic differentiation...
The lake minnow Eupallasella percnurus is distributed throughout a vast area that includes most of Europe and northern Asia displays wide range morphological variation, which resulted in five distinguished subspecies. There are no previous conclusive morphometric analyses samples from different parts the distribution area. This paper presents results multidimensional characters 19 widely scattered populations species. show considerable inter-population differences. Morphometric evidence...
The Eurasian minnow Phoxinus phoxinus is widely distributed across most of Europe and northern Asia. It displays considerable morphological diversity variable colouration. Despite this it still believed that its whole distribution holds only one monotypic species. There are no previous conclusive morphometric analyses samples from different parts area. This paper presents results multidimensional characters 14 scattered populations the Our show inter-population differences. Morphometric...
Abstract Bears undergo some significant changes reflected in blood values during winter season. The most are reduced urea and increased creatinine, by authors considered to be physiological indicators of hibernation. Studied group six captive brown bears ( Ursus arctos ) showed decreased activity but were accepting food walked outdoors. Blood parameters assessed February 2011 revealed mean leucocytes neutrophils as significantly lower, creatinine compared free living sampled other seasons...
The study aimed to determine reproductive span by investigation of the ovarian structures in young and elderly captive brown bear females (Ursus arctos).The ovaries two 2-year-old were obtained ovariectomy during necropsies 31 36 year old individuals.All examined macroscopically histologically.Histological examination animals (2+ years) revealed presence primordial, primary, secondary tertiary follicles within
