Poison dart frogs are well known for their deadly toxins and bright colours, which have made them a classic example of warning coloration.
The Dyeing Dart Frog, for example, is highly toxic and warns its predators with a bright yellow-and-black pattern.
However, new research led by scientists at the University of Bristol has revealed that the colour...
Chemical analysis of the remains of rats from archaeological sites spanning the last 2000 years on three Polynesian island systems has shown the impact that humans have had on local environments. The analysis by an international team of scientists allowed the researchers to reconstruct the rats' diets -- and through them the changes made by...
University of Wyoming researchers are shedding light on a rare aquatic beetle native only to central Wyoming.
Lusha Tronstad, lead invertebrate zoologist with the Wyoming Natural Diversity Database, a service and research unit housed at UW, says the narrow-footed Hygrotus diving beetle has been petitioned for Endangered Species Act listing three times in the past 11...
Poisonous moths use bright red spots to warn predators to avoid them -- but natural variation in these wing markings doesn't provide clear indications of how toxic individual moths might be -- new research shows.
University of Exeter scientists studied six-spot burnet moths, which produce cyanide-based compounds to make themselves a bad snack for predators, to...
The recent introduction of the common Asian toad to Madagascar has led to fears that the toxic amphibian could wreak havoc on the island's already severely threatened fauna. Now, researchers report genetic evidence in the journal Current Biology on June 4 showing that those fears are well founded: virtually all predators native to Madagascar are...
Scientists rely on the use of animal models to improve our understanding of lethal muscle-wasting disease Duchenne muscular dystrophy (DMD), and to develop safe new therapies. A newly developed rabbit model, created through the use of CRISPR/Cas-9 genome editing, exhibits greater clinical similarity to human patients than the mouse models currently in use, with huge...
