Habitat turnover definition8/30/2023 2016) produce composite population indices for two groups of breeding bird species across the United States and Europe: those for which climate suitability has been either improving or declining since 1980. 2016): The probability of occurrence of the meltwater stonefly (Lednia tumana) increased with cold stream temperatures and close proximity to glaciers and permanent snowfields, suggesting climate warming-induced glacier and snow loss imperils the species’ persistence throughout its range. 2017): The Great Basin treeline for the two dominant Great Basin sub-alpine species, limber pine and Great Basin bristlecone pine, is expanding upslope with a mean vertical elevation shift of 63 feet (19.1 meters) since 1950. Across all the 48 species, the interval between arrival and green-up increased by over half a day per year. 2017) finds that 9 of 48 migrating passerine bird species in North America did not keep pace with rapidly changing green-up over the period 2001–2012. 2017): Among North American and Hawaiian native bee species with sufficient data to assess (1,437), more than half (749) are declining nearly a quarter (347) are imperiled and at increasing risk of extinction and climate change is one of their major threats. Researchers found the shifts toward higher, cooler altitudes were accelerated in Douglas fir and canyon live oak in areas burned by wildfires.
