Conservation theory gets mathematical treatment
Theories used for the last four decades as a tool to guide the conservation of flora and fauna may have misinterpreted the biological reality, according to new research by mathematicians at the University ...
Birds time breeding to hit 'peak caterpillar'
When oaks burst into life in spring populations of oak-leaf-eating caterpillars boom: this offers a food bonanza for caterpillar-munching birds looking to raise a family.
Study uncovers why songbirds vary in time devoted to warming eggs
The amount of time and effort songbirds spend warming their eggs directly correlates to their own survival probability and that of their eggs, according to a study by University of Montana researchers that ...
Fish born in larger groups develop more social skills and a different brain 'architecture'
A new study shows that cichlid fish reared in larger social groups from birth display a greater and more extensive range of social interactions, which continues into the later life of the fish. Researchers ...
Variability helps mammals to become invasive
From the time humans began discovering and conquering new continents, they also started transporting animals and plants around the world and releasing them in locations where they never occurred before. Most ...
Research shows white sharks use sun to hunt prey
White Sharks – the world's largest predatory fish – have the impressive ability to follow the direction of the sun to hunt their prey, new research from Flinders University reveals.
Birth during a drought correlated with poor health in baboons
The saying "what doesn't kill you makes you stronger" may not hold up to scientific scrutiny.
Plants aren't in lockstep when responding to environmental changes
A study spearheaded by UConn graduate students has found that species of two plant families sharing the same habitat sometimes respond in different ways to key climate changes.
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.
After 60 million years apart, two fern genera form hybrid in the mountains of France
In an article published in the March 2015 issue of The American Naturalist, a team of researchers report on a fern from the French Pyrenees that is a recently formed intergeneric hybrid between parental lineag ...
Choosy fish females may boost biodiversity
A new study offers insight into a process that could lead one species to diverge into two, researchers report in the American Naturalist.
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 ...
