Lizard activity levels can help scientists predict environmental change
Spring is here and ectotherms, or animals dependent on external sources to raise their body temperature, are becoming more active. Recent studies have shown that as the average global temperature increases, ...
Loss of large predators tips ecosystem balance, according to study
A new study has linked the size of predators atop a food chain with the ecological chain reaction triggered when they leave the head of the table.

Hidden in plain sight: Amazonian bird chick mimics toxic caterpillar to avoid being eaten
In a study published in the January 2015 issue of The American Naturalist, Gustavo A. Londoño, Duván Garcia, and Manuel Sánchez Martínez report a novel nesting strategy observed in a tropical lowland bird t ...
Distant species produce love child after 60 million year breakup
A delicate woodland fern discovered in the mountains of France is the love child of two distantly-related groups of plants that haven't interbred in 60 million years, genetic analyses show.
Seeds out of season: New modeling framework elucidates the interaction between various life stages of a plant
Researchers have created a model that considers how different stages of a plant's life cycle interact with each other. Whereas previous studies have examined the seed, vegetative, and reproductive phases ...
