On the Ground • Kangaroo rats occur exclusively in arid environments of western North America, where they often function as ecosystem engineers and keystone species. • These rodents can exist on a diet of seeds without drinking free water. • Ka

Scatter-hoarding rodents store seeds throughout their home ranges in superficially buried caches which, unlike seeds larder-hoarded in burrows, are difficult to defend. Cached seeds are often pilfered by other scatter-hoarders and either re-cached, e

Retention and development of fruits containing inviable seeds has been considered anomalous, because such seeds cannot contribute to plant fitness. Although trees in the genus Juniperus are conifers and thus not true fruiting plants, junipers package

•Scatter-hoarding rodents constitute the primary means of seed dispersal and seedling establishment for a diversity of plant forms, including grasses, shrubs, and trees. We review evidence of the importance of scatter-hoarding rodents for the propa

Granivorous rodents commonly exhibit preferences for seeds of particular plant species. However, among buried seeds that are available, rodents may find that alternate, less desirable seeds are more easily located by olfaction than preferred seeds. S

Arthropods impact seed production in various juniper species, but effects of pre-dispersal seed predation are generally unknown for arthropods that feed on western juniper (Juniperus occidentalis). From 2009 to 2013, we quantified impacts of three ar

On the Ground • Although research on the behavior of individual animals has been growing in recent years, the role that individual variation among animals may play in the outcome of species interactions in nature may be somewhat overlooked in natur
