U.S. researchers say they've determined it will not be easy to scientifically predict the spread of invasive plants and animals. University of California-Davis Professor Alan Hastings and University of Colorado-Boulder Assistant Professor Brett Melbourne used a tightly controlled laboratory experiment and a mathematical model to reach their conclusion. When they released 600 identical beetles and allowed them to spread at will through 30 identical landscapes over 13 generations, they noted a...

Unknowns may place more species at risk in a changing climate Whether for introduced muskrats in Europe or oak trees in the United Kingdom, zebra mussels in United States lakes or agricultural pests around the world, scientists have tried to find new ways of controlling invasive species by learning how these animals and plants take over in new environs. In a paper published in this week's issue of the journal Science, biologists Brett Melbourne of the University of Colorado and Alan Hastings...

Extinction risks may be underestimated by as much as 100-fold, say researchers Extinction risks for natural populations of endangered species are likely being underestimated by as much as 100-fold because of a mathematical "misdiagnosis," according to a new study led by a University of Colorado at Boulder researcher. Assistant Professor Brett Melbourne of CU-Boulder's ecology and evolutionary biology department said current mathematical models used to determine extinction threat, or...
