Patterns of herbivory along a prouductivity gradient: An empirical and theoretical investigation

J van de Koppel, J Huisman, R van der Wal, H Olff - Ecology, 1996 - Wiley Online Library
According to classical exploitation theory, an increase of primary productivity should result in
increased herbivore grazing pressure, thus maintaining a low plant standing crop. However …

M Scheffer, EH Van Nes, M Holmgren, T Hughes - Ecosystems, 2008 - Springer
In systems ranging from lakes and woodlands to coral reefs, the long-term ecosystem state
may often be determined largely by rare extreme events such as wet ENSO years, droughts …

Vigilance and Collective Detection of Predators in Degus (Octodon degus)

LA Ebensperger, MJ Hurtado, R Ramos‐Jiliberto - Ethology, 2006 - Wiley Online Library
Individuals of social and partially social species typically reduce their vigilance activity when
foraging in groups. As a result, per capita risk of predation decreases and individuals …

On the Relationship between Herbaceous Cover and Vigilance Activity of Degus (Octodon degus)

LA Ebensperger, MJ Hurtado - Ethology, 2005 - Wiley Online Library
A number of studies demonstrate that plant cover provides prey animals with refuges to
decrease vulnerability to predators. However, others suggest plant cover to visually obstruct …

Influence of Habitat on Behavior of Townsend's Ground Squirrels (Spermophilus townsendii)

PB Sharpe, B Van Horne - Journal of Mammalogy, 1998 - academic.oup.com
