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

Invasive hybridization in a threatened species is accelerated by climate change

Research shows that rapid climate-warming has exacerbated interactions between native trout and the non-native species through invasive hybridization in western North America.

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.

Response to Comment on “Nuclear Genomic Sequences Reveal that Polar Bears Are an Old and Distinct Bear Lineage”

It is asserted that the mitochondrial DNA–based scenario for polar bear evolution cannot be refuted and the sister-lineage model receives high support in a Bayesian model comparison.

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.

Ancient Hybridization and an Irish Origin for the Modern Polar Bear Matriline

A Review on Animal Hybridization’s Role in Evolution and Conservation: Canis rufus (Audubon and Bachman) 1851—A Case Study

The term “cladogamy” is being proposed to substitute “hybridization” and to refer to the crossing between two any given clades, due to difficulties from scientists and eventual arbitrary means of separating species from lower taxa.
