![]() This is true for all aspects of climate change (e.g., temperature, humidity, and precipitation), but in particular, latitudinal variation in temperature is changing rapidly and can play a significant role in reproductive timing and behavior in many organisms ( Senner et al., 2017 ). These perturbations also offer a new opportunity to study the evolution of species boundariestheir persistence, formation, or collapseover rapid evolutionary timescales ( Brennan et al., 2015 Taylor et al., 2015 Grabenstein and Taylor, 2018 ). This critical period is a crisis for biodiversity ( Dirzo et al., 2014 Wiens, 2016 ), including insects ( Snchez-Bayo and Wyckhuys, 2019 ). We focus on studies that have tracked changes in climate and insect distributions andor have evaluated temperature dependent reproductive barriers between species.Ĭontemporary global change is altering species habitat at an unprecedented pace and scale. Here, we review the potential for climate change to influence gene flow and species boundaries between closely related insect species. ![]() This is particularly true for insects, whose geographic ranges, behaviors, and life history traits are temperature dependent.
