The findings give clues to the health and status of the threatened species
Researchers overcome winking, napping pigs to prove brain test works
URBANA, Ill. – If you’ve ever been to an eye doctor, there’s a good chance you’ve felt the sudden puff of air to the eye that constitutes a traditional test for glaucoma. It’s no one’s favorite experience, but the puff…
Zoo amphibians were on display while humans were locked away
While the UK was in lockdown, certain species of captive amphibians became more visible, a new study suggests. The COVID-19 pandemic forced the closure of zoos across the UK for several months from March 2020, with gradual re-openings from summer…
‘Smart collar’ could prevent tapeworms in dogs
Dogs infected with echinococcosis play a major role in spreading tapeworms across human populations around the world. Now, researchers have developed a “smart collar” which gradually delivers a steady dose of a deworming drug to dogs. The collar successfully reduces…
Arctic seabirds are less heat tolerant, more vulnerable to climate change
The Arctic is warming at approximately twice the global rate. A new study led by researchers from McGill University finds that cold-adapted Arctic species, like the thick-billed murre, are especially vulnerable to heat stress caused by climate change.
New method lets researchers rapidly monitor snow leopard stress levels in the wild
The newly developed method lets researchers rapidly and accurately measure stress hormones in snow leopards without the need for bulky equipment or specialised knowledge. It uses widely available equipment that can be carried into the field, allowing hormone extraction from…
