Predator learning favors mimicry of a less-toxic model in poison frogs
Article Abstract:
A study of a poison-frog mimicry complex comprising two parapatric models and a geographically dimorphic mimic that shows monomorphism where models co-occur is illustrated. It is found that predators differ in avoidance generalization depending on toxicity of the model, conferring greater protection to mimics resembling the less-toxic model owing to overlap of generalized avoidance curves.

Primitive Early Eocene bat from Wyoming and the evolution of flight and echolocation
Article Abstract:
The article discusses the evolutionary pathways of flight and echolocation in a new species of Primitive Early Eocene bat from Wyoming, USA. The findings reveal that the new bat can be an agile climber with under-branch hanging behavior due to its limb proportions and retention of claws.
