Predicting migration pathways of mule deer without GPS collars

How do researchers understand where big-game animals migrate across vast landscapes each spring and fall? That is the question asked by biologists from the University of Wyoming and Idaho Department of Fish and Game in a ...

Refined DNA tool tracks native and invasive fish

Rather than conduct an aquatic roll call with nets to know which fish reside in a particular body of water, scientists can now use DNA fragments suspended in water to catalog invasive or native species.

Determining where the wild bears are

Large land animals have a significant impact on the ecology and biodiversity of the areas they inhabit and traverse. If, for example, the routes and stopping places of cattle, horses, sheep, and also those of wolves or bears ...

Tracking pollen with quantum dots

A pollination biologist from Stellenbosch University in South Africa is using quantum dots to track the fate of individual pollen grains. This is breaking new ground in a field of research that has been hampered by the lack ...

A modeling tool to rapidly predict weed spread risk

In the study, published in the journal Methods in Ecology and Evolution, the researchers developed the tool that uses information about the features of a weed species and the geography of the area in which it has been reported ...

Flooding's impact on wetlands measurable via low-cost approach

Scientists designed a new, on-site method for studying potential impacts rising sea levels can have on vital wetlands, said a University of Alabama researcher who led a study publishing Aug. 17 describing the modifiable apparatuses.
