A comparative analysis of clinging ability among pad‐bearing lizards
- D. Irschick, C. C. Austin, K. Petren, R. Fisher, J. Losos, Olaf Ellers
- Biology
- 1 September 1996
We examined clinging ability, subdigital pad area and body mass in 14 pad-bearing lizard species from three families to test three predictions: (1) clinging ability and pad area should be tightly… Expand
The role of natural history collections in documenting species declines.
- H. B. Shaffer, R. Fisher, C. Davidson
- Biology, Medicine
- Trends in ecology & evolution
- 1998
Efforts to document the decline of extant populations require a historical record of previous occurrences. Natural history museums contain such information for most regions of the world, at least at… Expand
A Rapid, Strong, and Convergent Genetic Response to Urban Habitat Fragmentation in Four Divergent and Widespread Vertebrates
- K. Delaney, S. Riley, R. Fisher
- Biology, Medicine
- PloS one
- 16 September 2010
Background Urbanization is a major cause of habitat fragmentation worldwide. Ecological and conservation theory predicts many potential impacts of habitat fragmentation on natural populations,… Expand
The Decline of Amphibians in California’s Great Central Valley
- R. Fisher, H. B. Shaffer
- Geography
- 1 October 1996
Declines in amphibian populations are rarely reported on the community or ecosystem level. We combined broad-scale field sampling with historical anialyses of museum records to quantify anmphibian… Expand
Effects of Urbanization on the Distribution and Abundance of Amphibians and Invasive Species in Southern California Streams
- S. Riley, Gary T. Busteed, +6 authors R. Sauvajot
- Geography
- 1 December 2005
: Urbanization negatively affects natural ecosystems in many ways, and aquatic systems in particular. Urbanization is also cited as one of the potential contributors to recent dramatic declines in… Expand
Effects of urbanization on carnivore species distribution and richness
- Miguel A. Ordeñana, K. Crooks, +9 authors D. V. Van Vuren
- Geography
- 16 December 2010
Abstract Urban development can have multiple effects on mammalian carnivore communities. We conducted a meta-analysis of 7,929 photographs from 217 localities in 11 camera-trap studies across coastal… Expand
Quantifying ecological, morphological, and genetic variation to delimit species in the coast horned lizard species complex (Phrynosoma)
- A. Leaché, Michelle Koo, Carol L. Spencer, T. Papenfuss, R. Fisher, J. McGuire
- Biology, Medicine
- Proceedings of the National Academy of Sciences
- 28 July 2009
Lineage separation and divergence form a temporally extended process whereby populations may diverge genetically, morphologically, or ecologically, and these contingent properties of species provide… Expand
Uncertainty and Spatial Linear Models for Ecological Data

Understanding the genetic effects of recent habitat fragmentation in the context of evolutionary history: phylogeography and landscape genetics of a southern California endemic Jerusalem cricket…
- A. G. Vandergast, A. Bohonak, D. B. Weissman, R. Fisher
- Biology, Medicine
- Molecular ecology
- 21 December 2006
Habitat loss and fragmentation due to urbanization are the most pervasive threats to biodiversity in southern California. Loss of habitat and fragmentation can lower migration rates and genetic… Expand
Interfacing models of wildlife habitat and human development to predict the future distribution of puma habitat
- C. Burdett, K. Crooks, +7 authors W. Boyce
- Geography
- 1 July 2010
The impact of human land uses on ecological systems typically differ relative to how extensively natural conditions are modified. Exurban development is intermediate-intensity residential development… Expand
