Epigenetic Clock in Bears: A Simple Cost-Effective Blood DNA Methylation-Based Age Estimation Method Applicable to Multiple Bear Species. [PDF]

Ecol Evol
Age is an essential factor to understand the life history and demographic parameters of wildlife. In this study, we built a common epigenetic clock model for multiple bear species, including brown, Asian black, polar, sun, and Andean bears. The model will contribute to ecological research, conservation, and management of bear species.

Evidence of strong stabilizing effects on the evolution of boreoeutherian (Mammalia) dental proportions. [PDF]

, 2019
The dentition is an extremely important organ in mammals with variation in timing and sequence of eruption, crown morphology, and tooth size enabling a range of behavioral, dietary, and functional adaptations across the class.

Inferring palaeoecology in extinct tremarctine bears (Carnivora, Ursidae) using geometric morphometrics [PDF]

Lethaia, 2009
In this study we explore the ecomorphological patterns of extinct tremarctine bears in South America during the Great American Biotic Interchange (GABI). These patterns are used to derive palaeoautoecological inferences in extinct tremarctines and their palaeosinecological relationships within Plio-Pleistocene ecosystems.

Sequencing and assembling bear genomes: the bare necessities

Frontiers in Zoology, 2022
Unique genetic adaptations are present in bears of every species across the world. From (nearly) shutting down important organs during hibernation to preventing harm from lifestyles that could easily cause metabolic diseases in humans, bears may hold the
