(EurekAlert, University of Cambridge) Mammals, birds and amphibians worldwide have lost on average 18% of their natural habitat range as a result of changes in land use and climate change, a new study has found. In a worst-case scenario this loss could increase to 23% over the next 80 years.
(Bowling Green State University) Newly-funded research will look at how bees are impacted by climate change and urbanization. The research will focus on bees in five sets of paired cities that represent a wide range of temperatures and precipitation. The researchers have identified six groups of bees that are considered “economically important and in large enough quantities in each of the cities.” They plan to study honey bees, bumble bees, carpenter bees, sweat bees, mason bees and leafcutting bees.
(The Guardian) The diversity and resilience of cold-loving butterfly species is threatened by global heating which will destroy genetically unique populations, according to a study. Native mountain-dwelling butterflies such as the mountain ringlet, the bright-eyed ringlet and the dewy ringlet will have to be translocated to higher altitudes as their cooler habitat disappears to avoid extinction.
(Science) As the world’s climate changes, plants and animals have adapted by expanding into new territory and even shifting their breeding seasons. Now, research suggests that over the past 75 years, flowers have also adapted to rising temperatures and declining ozone by altering ultraviolet pigments in their petals.
(East Oregonian) While a lack of regional data doesn’t allow for definitive conclusions on how increased temperatures will impact regional bee populations, preliminary data alludes to the dangers they face. They suggest that as temperatures rise in the region, the variance and quantity of bumble bee species may decline.
(ScienceNews) A new study argues that nations can help avert the biodiversity and climate crises by preserving the roughly 50% of land that remains relatively undeveloped. The researchers dub that conserved area a “Global Safety Net,” mapping out regions that can meet critical conservation and climate goals.
(Georgia Institute of Technology) Reduced resilience of plant biomes in North America could be setting the stage for the kind of mass extinctions not seen since the retreat of glaciers and arrival of humans about 13,000 years ago, cautions a new study. “Our work indicates that landscapes today are once again exhibiting low resilience, foreboding potential extinctions to come. Conservation strategies focused on improving both landscape and ecosystem resilience by increasing local connectivity and targeting regions with high richness and diverse landforms can mitigate these extinction risks.”
(EurekAlert, Utah State University) “We find bee emergence timing is advancing with snowmelt timing, but bee phenology – timing of emergence, peak abundance and senescence – is less sensitive than flower phenology. Given global concerns about pollinator declines, the research provides important insight into the potential for reduced synchrony between flowers and their pollinators under climate change.”
