DOI: 10.1007/s00442-019-04385-1
Abstract: Ungulates are important to the diet of bears because they are high in protein, and the level of dietary protein strongly influences bear size. The size a bear obtains as an adult influences important life… read more here.

DOI: 10.1038/s41598-019-38937-5
Abstract: Human foods have become a pervasive subsidy in many landscapes, and can dramatically alter wildlife behavior, physiology, and demography. While such subsidies can enhance wildlife condition, they can also result in unintended negative consequences on… read more here.

DOI: 10.1038/s41598-020-77282-w
Abstract: The gut microbiome (GMB), comprising the commensal microbial communities located in the gastrointestinal tract, has co-evolved in mammals to perform countless micro-ecosystem services to facilitate physiological functions. Because of the complex inter-relationship between mammals and… read more here.

DOI: 10.1093/beheco/ary020
Abstract: When black bears cross roads, their HRs increase, indicating heightened alertness to danger. Wildlife reacts to roads in various ways, but it is unknown whether road crossings are stressful. We monitored black bears with cardiac… read more here.

DOI: 10.1111/ddi.12666
Abstract: Aim In the mid-20th century, many populations of large-bodied mammals experienced declines throughout North America. Fortunately, within the last several decades, some have begun to rebound and even recolonize extirpated portions of their native range,… read more here.
