“U.S. Geological Survey (USGS) scientists and collaborators discovered that long-wave ultraviolet (UV) light directed at the wings of bats with white-nose syndrome (WNS) produced points of distinctive orange-yellow fluorescence. The orange-yellow glow corresponds directly with microscopic skin lesions that define the current “gold standard” for diagnosing WNS.”
Hybridization patterns in two contact zones of grass snakes reveal a new Central European snake species | Scientific Reports
This is amazing news. Natrix natrix -previously thought to be the only grass snake in the UK – has been found to be genetically distinct from what was previously thought to be a variation rather than separate species, the newly named Natrix venaticus. Studies sampled mtDNA from existing skins and specimens and found clear genetic differences between the two, confirming Natrix venaticus as a separate and distinct species. No living snakes were harmed for the study either, which is always good news.
So I’m writing an essay about drivers of coral reef bleaching, and reading about acidification and its effects on marine mammals that secrete calcium carbonate, and this new research pops up. Interesting immediate adaptation to cope with lower pH levels in marine environments; although I’m not sure how long-term (and effective) an adaptation it might be. Similarly, some coral species and their symbionts are more tolerant of some drivers of bleaching than others. Again, in the short-term that helps those species, but it’s not clear how far beyond their normal thresholds for CO2, irradiance, thermal stress and acidification they can survive. And then there’s coral diseases… We are pushing the limits, changing environments and testing tolerance thresholds for so much of the world’s wildlife, and not in a good way.
The science is there. Will governments and hunters pay any attention to it?
Roosting in conical leaves reduces the clarity of bat communications – A new zoology thing for curious kids – 2 New Things
“Spix’s disk-winged bats don’t live the standard cave-bound lifestyle we usually associate with flying mammals. The natives of Central and South America generally roost in the thick, curled leaves of plants like calatheas. Weighting in at only four grams, a handful of bats can hide in a single furled leaf, hanging on thanks to the suction-cup disks on their wings and legs that they’re named for.”
