Advanced Functional Materials, EarlyView.This work reports the first gram‐scale solvothermal synthesis of ‘Rubik's cube’ nanoparticles—cubic, dendritic multicore structures with tuneable sizes and exceptional magnetic heating performance. Featuring iron oxide single‐domain character, with low coercivity fields, high magnetization, and strong MPI signals, they enable viscosity‐independent ...

Reindeer habitat selection under the risk of brown bear predation during calving season
Ecosphere, 2016 The depredation of semi‐domesticated reindeer by large carnivores reflects an important human–wildlife conflict in Fennoscandia. Recent studies have revealed that brown bears (Ursus arctos) may kill substantial numbers of reindeer calves (Rangifer ...

Advanced Functional Materials, EarlyView.Photothermal, macroporous lignin‐based cryogels are engineered to convert sunlight into low‐grade heat. Integrated as stacked beds in a drum‐type device, a thin copper interlayer transfers waste heat between beds, enabling interlayer heat recovery and continuous solar cycling.

Genetic and demographic recovery of an isolated population of brown bear Ursus arctos L., 1758 [PDF]
, 2016 The brown bear Ursus arctos L., 1758 population of the Cantabrian Mountains (northwestern Spain) became isolated from other bear populations in Europe about 500 years ago and has declined due to hunting and habitat degradation.

Introgressive hybridization: brown bears as vectors for polar bear alleles [PDF]
Molecular Ecology, 2015 The dynamics and consequences of introgression can inform about numerous evolutionary processes. Biologists have therefore long been interested in hybridization. One challenge, however, lies in the identification of nonadmixed genotypes that can serve as a baseline for accurate quantification of admixture.

Brown bear den characteristics and selection in eastern Transylvania, Romania
Journal of Mammalogy, 2020 Dens are important for species that need to survive and reproduce during harsh winters. Brown bears (Ursus arctos) in Romania, listed by the European Union as a population of concern, use dens for several months each year.

Advanced Functional Materials, EarlyView.This study shows that lizard osteoderm capping tissue is a hyper‐mineralized hydroxyapatite layer consistently covering the superficial osteoderm surface in those species studied here, yet it varies greatly in morphology, nanostructure, and mechanical performance across species.

Status and Food Preferences of Bears in Sub Alpine Scrub Forests, AJK
Journal of Bioresource Management, 2018 Bears belong to the family Ursidae, under the order Carnivora with eight extant species (Grzimek, 2003). Roberts (1997) cite the presence of Himalayan brown bear, Himalayan black bear and Balochistan black bear in Pakistan.

Questioning current practice in brown bear, Ursus arctos, conservation in Europe that undervalues taxonomy [PDF]
Animal Biodiversity and Conservation, 2016 The present paper highlights problems associated with the currently–accepted taxonomy of brown bear, Ursus arctos, and their consequences for conservation at the European level.
