Hybridization in polar species could hit biodiversity hard, say Brendan Kelly, Andrew Whiteley and David Tallmon. 
Climate-induced range overlap among closely related species
Bioclimatic modelling suggests that as species distributions shift in response to climate change, few currently isolated but closely related species are likely to come into contact, implying that
Legacy introductions and climatic variation explain spatiotemporal patterns of invasive hybridization in a native trout
Evaluated spatiotemporal dynamics of hybridization between native cutthroat trout and invasive rainbow trout across the Northern Rocky Mountains of the United States show that effects of climate change on biodiversity must be analyzed in the context of historical human impacts that set ecological and evolutionary trajectories.
Risk and efficacy of human‐enabled interspecific hybridization for climate‐change adaptation: response to Hamilton and Miller (2016)
This study highlights the need to understand more fully the role of snowmelt in the decline of grizzly bear populations in the Northern Rocky Mountain region.
Evolutionary History of Polar and Brown Bears
Taxonomists have long recognised polar and brown bears as separate species with distinct ecological niches and largely nonoverlapping ranges. Surprisingly, phylogenetic studies of maternally
The Ethics of Species: An Introduction
The value of species, the conservation biology dilemma, and the (in)significance of species boundaries are discussed.
Hybridization does not currently pose conservation concerns to murres in the Atlantic
The results suggest that hybridization between Atlantic murre species is rare, and does not currently pose a conservation concern for either species, as well as providing baseline data for monitoring hybrids between murres in the Atlantic to assess future impacts of climate change on these species.

Genetic Relationships of Extant Brown Bears ( Ursus arctos ) and Polar Bears ( Ursus maritimus )
Genetic distances, proportion of private alleles, and Bayesian cluster analysis are consistent with morphological and life-history characteristics that distinguish polar bears and brown bears as different species with little or no gene flow among extant populations.
Ecological Consequences of Sea-Ice Decline
After a decade with nine of the lowest arctic sea-ice minima on record, including the historically low minimum in 2012, this work synthesizes recent developments in the study of ecological responses to sea- ice decline to assign clearer attribution to sea ice as a primary driver of such dynamics.
