Den characteristics and ecological significance of Marmota himalayana on the Qinghai-Tibet Plateau [PDF]

, 2021
Dens are places for cavernicolous animals to hibernate, reproduce, and avoid predators and harsh weather conditions, and thus they have a vital impact on their survival. M. himalayana is the main large cavernicolous rodent on the Qinghai-Tibet Plateau. The analysis of den traits and their ecological functions can reveal mechanisms by which marmots have

An experimental assessment of social tolerance and den ecology in a high-density octopus population [PDF]

Marine Biology, 2021
AbstractLong held notions of the universally asocial octopus are being challenged due to the identification of high-density and interacting octopus populations in Australia, Indonesia, Japan and the deep sea. This study experimentally assessed the social tolerance and presence of potential prey items of Caribbean reef octopus, Octopus briareus, in a ...

Winter insomnia: How weather conditions and supplementary feeding affect the brown bear activity in a long-term study

Global Ecology and Conservation, 2019
Climate change and anthropogenic food subsidies affect wildlife everywhere in the world. We used a 30-year set of data on winter observations of brown bear Ursus arctos to investigate the effects of weather and supplementary feeding on bear winter ...

Relationship of the productivity of forest den-drocenoses with the geomorphological profile of soils and their influence on the ecology [PDF]

E3S Web of Conferences, 2021
It is well known that there is a relationship between the productivity of forest phytocenoses and soil fertility, which is largely determined by the terrain and soil geomorphology. An important element of assessing the productivity of forests is the substantiation of the methodology for modeling the age dynamics of the growth of forest stands ...

The seasonal sensitivity of brown bear denning phenology in response to climatic variability

Frontiers in Zoology, 2018
Background For brown bears (Ursus arctos), hibernation is a critical part of the annual life cycle because energy savings during hibernation can be crucial for overwintering, and females give birth to cubs at that time.

Assessing the role of dens in the spread, establishment and persistence of sarcoptic mange in an endangered canid

Epidemics, 2019
Sarcoptic mange is a skin disease caused by the mite Sarcoptes scabiei that can devastate populations of wild species. S. scabiei can survive off-host and remain infective for specific periods.

Dwellers in dens on sandy bottoms: Ecological and behavioural traits of Octopus vulgaris

Scientia Marina, 2014
Four visual censuses targeting Octopus vulgaris living in dens on sandy bottoms were carried out from June to October 2013 in the National Park of the Atlantic Galician Islands (NW Spain). Censuses were undertaken by scuba diving between 5 and 21 m depth in daytime. The total area swept was 13.75 ha.

Denning Ecology of Wolves in East-Central Alaska, 1993–2017

ARCTIC, 2018
 Dens are a focal point in the life history and ecology of gray wolves (Canis lupus), and their location can influence access to key resources, productivity, survivorship, and vulnerability to hunting, trapping, and control efforts. We analyzed the selection of den sites and the phenology of their use inside the Yukon-Charley River National Preserve ...

Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)

The Anatomical Record, EarlyView.
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.
