Invasion, competitive dominance, and resource use by exotic and native California grassland species
The dynamics of invasive species may depend on their abilities to compete for resources and exploit disturbances relative to the abilities of native species. We test this hypothesis and explore itsExpand

Challenges and Opportunities of Open Data in Ecology
Ecology is a synthetic discipline benefiting from open access to data from the earth, life, and social sciences. Technological challenges exist, however, due to the dispersed and heterogeneous natureExpand

Spatial and temporal variation of seed distributions in Sonoran Desert soils
Samples taken in seventeen different microhabitats in the Sonoran Desert, NW of Tucson, Arizona (U.S.A.), revealed large variation in spatial (78-fold) and temporal (28-fold) patterns of seedExpand

The role of pocket gophers as subterranean ecosystem engineers
Pocket gophers (Geomyidae) and their ecological cognates worldwide have profound impacts on ecosystems, from consuming vegetation to altering the soil physically. The rodents excavate vast burrowExpand

The Evolution of Food Caching by Birds and Mammals
We limit our discussion of food storage, or caching, to the movement of potential food items from one location to another for eating at some later time. This activity occurs exclusively in thoseExpand

The New Bioinformatics: Integrating Ecological Data from the Gene to the Biosphere
We describe informatics frameworks for ecology, from subject-specific data warehouses, to generic data collections that use detailed metadata descriptions and formal ontologies to catalog and cross-reference information. Expand

Physiology on a Landscape Scale: Plant-Animal Interactions1
Abstract We explore in this paper how animals can be affected by variation in climate, topography, vegetation characteristics, and body size. We utilize new spatially explicit state-of-the-art modelsExpand
