We impersonated predators and prey to study trophic interactions. It was quite fun, but mostly, it worked

Post provided by David Bolduc and Frederic Dulude-de Broin Most people have played some form of tag during childhood – games where certain players try to catch others, who in turn may be able to take refuge in designated areas, or who must collect a flag or another item to win the game. These games are fun and engaging perhaps because they tap into some … Continue reading We impersonated predators and prey to study trophic interactions. It was quite fun, but mostly, it worked

Estimating seed predation rates

Seed predation plays an important role in global plant demography. In this video, Adam Davis, of the University of Illinois, demonstrates how field experiments and statistical models can can enable the extrapolation of long-term seed predation rates from short-term data. A full treatment of this can be found in the paper Temporal scaling of episodic point estimates of seed predation to long-term predation rates, recently … Continue reading Estimating seed predation rates

Detecting effects of predators on prey: the method matters

In a paper published online today in Methods in Ecology and Evolution, Malcolm Nicoll and Ken Norris look at a controversial issue, that of detecting effects of predators on bird populations. This is controversial because some predators, especially raptors, were formerly rather scarce, but have become more abundant in recent years – in the case of raptors because organochloride chemicals are not used any more. … Continue reading Detecting effects of predators on prey: the method matters
