UCLA life scientists and colleagues have produced the most comprehensive mathematical model ever devised to track the health of populations exposed to environmental change.

The research, federally funded by the National Science Foundation, is published Dec. 2 in the journal Science.

The team’s groundbreaking integral projection model, or IPM, unites various sub-disciplines of population biology, including population ecology, quantitative genetics, population genetics, and life-span and offspring information, allowing researchers to link many different data sources simultaneously. Scientists can now change just a single variable, like temperature, and see how that affects many factors for a population. (more…)

*Invasive Asian longhorned beetle has potential for wide reach in region’s forests*

Are new England’s iconic maple trees at risk? If a beetle has its way, the answer may be yes.

Results from the first study of the Asian longhorned beetle (ALB) in forests show that the invasive insect can easily spread from tree-lined city streets to neighboring forests. (more…)

GAINESVILLE, Fla. — Over the past two decades, Florida cattle ranchers have spent as much as $16 million a year doing battle with an invasive weed called tropical soda apple, known as TSA, that takes over pastures, elbowing out the forage grasses ranchers need for their cattle.

But a beetle released by the University of Florida’s Institute of Food and Agricultural Sciences is taking a bite out of the problem by feeding on the weed and reducing its competitiveness. UF researchers describe the beetle’s success as a biological control agent in the current issue of the journal Florida Entomologist. (more…)
