Published in: Science Authors: Bonnet et al (there are 40!) Abstract: The rate of adaptive evolution, the contribution of selection to genetic changes that increase mean fitness, is determined by the additive genetic variance in individual relative fitness. To date, there are few robust estimates of this parameter for natural populations, and it is therefore […]
Published in: Evolutionary Ecology Authors: Alexis Rutschmann, Pierre de Villemereuil, Patricia Brekke, John G. Ewen, Neil Anderson and Anna W. Santure Abstract: In heterogeneous habitats, individuals sharing a larger part of their home-range are also likely to live in a very similar environment. This ‘common environment’ effect can generate phenotypic similarities between neighbours and lead to the […]
Published in: Evolutionary Applications Authors: Pierre de Villemereuil, Alexis Rutschmann, John Ewen, Anna Santure & Patricia Brekke Abstract: Many bird species have been observed shifting their laying date to earlier in the year in response to climate change. However, the vast majority of these studies were performed on nonâ€threatened species, less impacted by reduced genetic […]
Published in: Current Biology Authors: Pierre de Villemereuil, Alexis Rutschmann, Kate Lee, John Ewen, Patricia Brekke & Anna Santure Abstract: Threatened species face numerous threats, including future challenges triggered by global change. A possible way to cope with these challenges is through adaptive evolution, which requires adaptive potential. Adaptive potential is defined as the genetic […]
One of New Zealand’s rarest native birds has shown how threatened species everywhere are facing a tougher time adapting to our fast-changing planet. Scientists have already shown how domesticated animals and wild creatures that aren’t threatened can adapt to different environments if they’re flexible enough, could shift ranges, or can simply evolve. But new research […]
