(University of Virginia) “While migration is often viewed as a means for species to proliferate in new environments, in this research we find that there also are inherent perils of expansion, such as a shallow gene pool. While migration will lead to individuals that are better able to reproduce in the small populations expected in new habitats, it may also cause genetic change that limits their ability to survive in the long term.”
(Xerces Society) Planting trees is an important action many of us can take to help fight the climate crisis. It’s also an action that will have a significant impact on pollinator conservation. The urban heat island effect, which is caused by large amounts of impervious surfaces, poses serious problems not only for the humans living in urban areas, but for the bee populations living there too. However, trees can provide a signifiant cooling effect in these urban areas that benefit both people and pollinators.
(University of Wyoming) Bumble bees and other bee species are in decline worldwide. “We know climate plays a role… Understanding their temperature tolerance will be really important in determining how they will adapt to changing temperatures.”
(Tufts University) Researchers conclude that low-quality habitats – such as urban environments – that meet a minimum standard could actually provide a benefit as conduits for species to migrate to high-quality habitats in the face of climate change. TBR Editor: Of course, this all presumes there’s actual high-quality habitat to move to…
