Students at the University of Windsor can now measure the stress levels of a pickerel swimming against a strong current, the turbidity of hazy tributaries feeding into the Great Lakes, and the behaviour of the invasive sea lamprey without wading into remote and distant waters.

The Freshwater Restoration Ecology Centre in LaSalle is the only research facility of its kind in the Great Lakes Basin and provides students with state-of-the-art technology to study the restoration of damaged ecosystems, invasive species biology and water quality.

Researchers from the U.S. Geological Survey, Taronga Conservation Society Australia, The National Trust of Fiji and NatureFiji-MareqetiViti have discovered a new species of banded iguana.

The new species of lizard, Brachylophus gau, is one of only four living species of South Pacific iguana, and is restricted to the island of Gau, Republic of Fiji. The scientists describe this new addition in an article released with the journal Zootaxa.

Wild capuchin monkeys readily learn skills from each other — but that social learning is driven home by the payoff of learning a useful new skill. It’s the first demonstration of “payoff bias” learning in a wild animal, and could inform whether and how animals can adapt to rapidly changing conditions, for example due to climate change or reintroduction of species from captive breeding.  

A new study led by the U.S. Geological Survey and the University of Wyoming found that increased westward ice drift in the Beaufort and Chukchi seas requires polar bears to expend more energy walking eastward on a faster moving “treadmill” of sea ice.  

These findings represent the first assessment of the consequences of changing drift rates for polar bears; one of several previously unexplored effects of sea ice loss.

Noise from motorboats is making fish become bad parents, and reducing the chance of their young surviving, research led by marine experts at the University of Exeter has shown.

The sound of motorboat engines disturbed coral reef fish so acutely it changed the behaviour of parents, and stopped male fish properly guarding their young, feeding and interacting with their offspring.

Climate change causes ecological variation and affects the lives of animals. The ever-earlier springs and later autumns caused by rising temperatures cause changes to animals’ physiology, breeding seasons and even population distributions. However, little is still known about how animals behave in response to these disturbances.

A landmark 30-year-long UNSW study of wetlands in eastern Australia has found that construction of dams and diversion of water from the Murray-Darling Basin have led to a more than 70 percent decline in waterbird numbers.

Artificial light at night can have a disruptive effect on bats, but not if the light is red. Switching to red light may therefore limit or prevent habitat loss for rare, light-shy bat species. The latest issue of Proceedings of the Royal Society B publishes results from five years of pioneering research led by the Netherlands Institute of Ecology (NIOO-KNAW).

Biologists have confirmed white-nose syndrome in the southeastern bat, or Myotis austroriparius, for the first time. The species joins eight other hibernating bat species in North America that are afflicted with the deadly bat fungal disease.

Pizza enthusiasts know well that a simple u-shaped curvature at the crust can keep a thin slice from drooping over when lifted from a plate. A team of engineers from Brown University has shown that fish may take advantage of roughly the same dynamics to stiffen their fins for swimming.
