- 1 March 2006
6 Climatic changes associated with the El Nino Southern Oscillation (ENSO) can have a dramatic impact on ter- restrial ecosystems worldwide, but especially on arid and semiarid systems, where… Expand
Thirteen Years of Shifting Top-Down and Bottom-Up Control
- P. Meserve, D. Kelt, W. B. Milstead, J. Gutiérrez
- Biology
- 1 July 2003
Abstract For 13 years, we studied the role of biotic interactions, including predation, herbivory, and interspecific competition, in a semiarid thorn scrub community in north-central Chile. Using a… Expand
Global variation in elevational diversity patterns
While horizontal gradients of biodiversity have been examined extensively in the past, vertical diversity gradients (elevation, water depth) are attracting increasing attention. We compiled data from… Expand
Analysis of determinants of mammalian species richness in South America using spatial autoregressive models
- Marcelo F. Tognelli, D. Kelt
- Mathematics
- 1 August 2004
Classically, hypotheses concerning the distribution of species have been explored by evaluating the relationship between species richness and environmental variables using ordinary least squares… Expand
Population dynamics of two sympatric rodents in a variable environment: rainfall, resource availability, and predation.
- M. Previtali, M. Lima, P. Meserve, D. Kelt, J. Gutiérrez
- Biology, Medicine
- Ecology
- 1 July 2009
Precipitation plays an important role in the dynamics of species found in arid and semiarid environments. However, population fluctuations generally are driven by a combination of multiple factors… Expand
SCALE-DEPENDENT PATTERNS IN BODY SIZE DISTRIBUTIONS OF NEOTROPICAL MAMMALS
- Victoria J. Bakker, D. Kelt
- Geography
- 1 December 2000
We report on the spatial scaling of body size distributions in the mammalian fauna of South America, exclusive of fully aquatic or volant species. Although the frequency distribution of body sizes… Expand
Effects of fire on spotted owl site occupancy in a late-successional forest
- S. L. Roberts, J. Wagtendonk, A. K. Miles, D. Kelt
- Geography
- 2011
Abstract The spotted owl ( Strix occidentalis ) is a late-successional forest dependent species that is sensitive to forest management practices throughout its range. An increase in the frequency and… Expand
The Ecology and Macroecology of Mammalian Home Range Area
- D. Kelt, D. V. Van Vuren
- Biology, Medicine
- The American Naturalist
- 1 June 2001
Although many studies employ allometric relationships to demonstrate possible dependence of various traits on body mass, the relationship between home range size and body mass has been perhaps the… Expand
Community Structure of Desert Small Mammals: Comparisons Across Four Continents
- D. Kelt, J. Brown, +5 authors G. Shenbrot
- Geography
- 1 April 1996
Presence/absence data for the small-mammal species at sites in seven deserts were analyzed for evidence of similarity in community structure. The deserts studied were located in North and South… Expand
NEST TREES OF NORTHERN FLYING SQUIRRELS IN THE SIERRA NEVADA
Abstract We examined the nest-tree preferences of northern flying squirrels (Glaucomys sabrinus) in an old-growth, mixed-conifer and red fir (Abies magnifica) forest of the southern Sierra Nevada of… Expand
