Coyotes “Shrank,” Wolves Did Not, After Last Ice Age and Megafaunal Extinctions

*Once large and wolf-like, coyotes ultimately became much smaller*

When the last ice age ended more than 10,000 years ago, many large species of mammals went extinct and others underwent changes in appearance. (more…)

Powerful Mathematical Model Greatly Improves Predictions for Species Facing Climate Change

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…)
