Lewis C, Melhedegaard E, Ognjanovic M, Olsen M, Laitila J, Seaborne R, et al.
bioRxiv . 2023 Nov; PMID: 38014200
Hibernation is a period of metabolic suppression utilized by many small and large mammal species to survive during winter periods. As the underlying cellular and molecular mechanisms remain incompletely understood,...

Chmura H, Duncan C, Burrell G, Barnes B, Buck C, Williams C
Science . 2023 May; 380(6647):846-849. PMID: 37228197
Climate warming is rapid in the Arctic, yet impacts to biological systems are unclear because few long-term studies linking biophysiological processes with environmental conditions exist for this data-poor region. In...

Haan T, Smith L, DeRonde S, House E, Zidek J, Puhak D, et al.
Viruses . 2023 Jan; 15(1). PMID: 36680262
Alaska is a unique US state because of its large size, geographically disparate population density, and physical distance from the contiguous United States. Here, we describe a pattern of SARS-CoV-2...

Toien O, Barnes B, Ruf T
Proc Biol Sci . 2022 Dec; 289(1984):20221396. PMID: 36476007

Haan T, Smith L, DeRonde S, House E, Zidek J, Puhak D, et al.
Sci Rep . 2022 Nov; 12(1):20662. PMID: 36450812
Alaska has the lowest population density in the United States (US) with a mix of urban centers and isolated rural communities. Alaska's distinct population dynamics compared to the contiguous US...

Chmura H, Duncan C, Saer B, Moore J, Barnes B, Buck C, et al.
Integr Comp Biol . 2022 Jul; 62(4):1012-1021. PMID: 35790133
Many animals adjust the timing of seasonal events, such as reproduction, molt, migration, and hibernation, in response to interannual variation and directional climate-driven changes in temperature. However, the mechanisms by...

Chmura H, Duncan C, Saer B, Moore J, Barnes B, Buck C, et al.
Commun Biol . 2022 May; 5(1):492. PMID: 35606540
Hibernation involves prolonged intervals of profound metabolic suppression periodically interrupted by brief arousals to euthermy, the function of which is unknown. Annual cycles in mammals are timed by a photoperiodically-regulated...

Goropashnaya A, Toien O, Ramaraj T, Sundararajan A, Schilkey F, Barnes B, et al.
Sci Rep . 2021 Apr; 11(1):8281. PMID: 33859306
Physical inactivity leads to losses of bone mass and strength in most mammalian species. In contrast, hibernating bears show no bone loss over the prolonged periods (4-6 months) of immobility...

Goropashnaya A, Barnes B, Fedorov V
Sci Rep . 2020 Jun; 10(1):9010. PMID: 32488149
Physical inactivity generates muscle atrophy in most mammalian species. In contrast, hibernating mammals demonstrate limited muscle loss over the prolonged intervals of immobility during winter, which suggests that they have...
