Predator foraging response to a resurgent dangerous prey

Aimee Tallian, Douglas W. Smith, Daniel R. Stahler, Matthew C. Metz , Rick L. Wallen, Chris Geremia, Joel Ruprecht, C. Travis Wyman, Daniel R. MacNulty ‘Prey switching’ refers to a change in the diet of a predator as the abundance of two prey species changes. Prey switching is ecologically important because it can stabilize prey…

Do different beetle trophic groups recover after logging the same way?

Nicholas M. Fountain-Jones, Gregory J. Jordan, Christopher Burridge, Timothy J. Wardlaw, Thomas P. Baker, Lynette Forster, Morgana Petersfield and Susan C. Baker Beetles are not only the most species rich group of animals, but are also very diverse in function, ranging from predators and parasites to herbivores and decomposers breaking down plant material. In forest…

Parasites getting into trouble in murky waters

Alexandre Budria Eutrophication is a type of water pollution caused by human activities, such as intensive agriculture or waste discharges, which notably stimulates the growth of microalgae and makes the water murky. Nowadays, this disturbance constitutes a major threat to most water bodies because it causes direct changes in aquatic ecosystems, including excessive algal growth,…

Coexisting tree species share similar characteristics

Mickaël Chauvet, Georges Kunstler, Jacques Roy, Xavier Morin Most forests in Central Europe are composed of many tree species. How do so many species co-exist in the long-term? Using a simplified sequential view of species assembly, the abiotic conditions first select a set of species that can colonize a site, depending on their tolerances to…

Long-term time series of legume cycles in a semi-natural montane grassland: evidence for nitrogen-driven grass dynamics?

Tomáš Herben, Hana Mayerová, Hana Skálová, Věra Hadincová , Sylvie Pecháčková, František Krahulec The extraordinary species richness of mountain grasslands often hides less obvious dynamics of individual species, which may appear and disappear over time. One of the conspicuous examples is cycles of legumes (such as clover). Importantly, legumes, in contrast to most other grassland…

Fear makes you fat, but not too fat to fly

Benjamin T. Walters, Tin Nok Natalie Cheng, Justin Doyle, Chistopher G. Guglielmo, Michael Clinchy and Liana Y. Zanette Escaping from a predator is a matter of ongoing life or immediate death. While escape ability is clearly imperative for survival, the variables that impair or improve it are not well understood. Escape ability is frequently assumed…
