Natural hybridization reduces vulnerability to climate change

چکیده
Abstract Under climate change, species unable to track their niche via range shifts are largely reliant on genetic variation adapt and persist. Genomic vulnerability predictions used identify populations that lack the necessary variation, particularly at climate-relevant genes. However, hybridization as a source of novel adaptive is typically ignored in genomic studies. We estimated environmental models for closely related rainbowfish ( Melanotaenia spp.) across an elevational gradient Australian Wet Tropics. Hybrid between widespread generalist several narrow endemic exhibited reduced projected climates compared pure endemics. Overlaps introgressed regions were consistent with signal introgression. Our findings highlight often-underappreciated conservation value hybrid indicate introgression may contribute evolutionary rescue ranges.

The focus of the great majority of climate change impact studies is on changes in mean climate. In terms of climate model output, these changes are more robust than changes in climate variability. By concentrating on changes in climate means, the full impacts of climate change on biological and human systems are probably being seriously underestimated. Here we briefly review the possible impact...

متن کاملNatural solutions to climate change
Fifty years ago, humans harboured the hubristic idea that they could alter the weather and climate to their advantage, perhaps to prevent future ice ages or to induce rainfall in drought-stricken regions. these high-flying hopes were eventually doused by reality; today, we have the more humble objective of merely keeping the climate stable—in particular, mitigating the impact of greenhouse gase...
