Abstract Herbivory is a major energy transfer within ecosystems; an open question is under what circumstances it can stimulate aboveground seasonal primary production. Despite multiple field demonstrations, past theory considered herbivory as a conti

The mechanisms by which grazing animals influence aboveground net primary production (ANPP) in grasslands have long been an area of active research. The prevailing wisdom is that grazing can increase ANPP by increasing the availability of growth-limi

Plant litter decomposition is a key process that influences carbon and nutrient cycling in terrestrial ecosystems. Litter decomposition is controlled by a number of factors such as temperature, moisture, litter quality, and the composition of soil mi

We studied the long-nosed leopard lizard, Gambelia wislizenii, in the Great Basin Desert of southeastern Oregon to identify intraspecific patterns of behavioral variation. Sex and body size played an important role in determining intraspecific behavi

Predation risk influences decision making, escape behaviour, and resource use. Risk assessment and behavioural responses to predation can depend on demographic and environmental factors. We studied the escape behaviour of the long-nosed leopard lizar
