  • 1 November 2002
Although differences in sampling intensity can bias comparisons of allelic richness (A) among populations, investigators often fail to correct estimates of A for differences in sample size. MethodsExpand

Breeding distributions of north American bird species moving north as a result of climate change.
Geographic changes in species distributions toward traditionally cooler climes is one hypothesized indicator of recent global climate change. We examined distribution data on 56 bird species. IfExpand

Experimental evaluation of the usefulness of microsatellite DNA for detecting demographic bottlenecks
Evolutionary and conservation biologists often use molecular markers to evaluate whether populations have experienced demographic bottlenecks that resulted in a loss of genetic variation. WeExpand

Biases associated with population estimation using molecular tagging
Although capture‐recapture techniques are often used to estimate population size, these approaches are difficult to implement for a wide variety of species. Highly polymorphic microsatellite markersExpand

DAY-ROOST SELECTION BY RAFINESQUE'S BIG-EARED BATS (CORYNORHINUS RAFINESQUII) IN LOUISIANA FORESTS
Abstract Availability of bridge roosts is a poorly understood but possibly important component underlying abundance and distribution of the potentially threatened bat Corynorhinus rafinesquii. WeExpand

GENETIC APPROACHES FOR ESTIMATING THE EFFECTIVE SIZE OF POPULATIONS
Abstract The effective population size (Ne) provides information on how fast genetic variation is being lost, or relatedness is increasing, in a population of interest. This parameter is oftenExpand

Habitat fragmentation and genetic diversity of an endangered, migratory songbird, the golden‐cheeked warbler (Dendroica chrysoparia)
Landscape genetic approaches offer the promise of increasing our understanding of the influence of habitat features on genetic structure. We assessed the genetic diversity of the endangeredExpand

Interactions of Salinity, Marsh Fragmentation and Submerged Aquatic Vegetation on Resident Nekton Assemblages of Coastal Marsh Ponds
Increases in relative sea level are fragmenting the emergent vegetation of Louisiana’s coastal marshes. Nekton abundance is likely impacted by salinity and whether emergent vegetation is replaced byExpand

Role of inbreeding depression and purging in captive breeding and restoration programmes
Inbreeding depression is a major force affecting the evolution and viability of small populations in captive breeding and restoration programmes. Populations that experience small sizes may be lessExpand

CLASSIFICATION BIAS IN DISCRIMINANT FUNCTION ANALYSES USED TO EVALUATE PUTATIVELY DIFFERENT TAXA
Abstract Discriminant function analysis has been used to assess morphological distinctiveness of putatively different taxa. We used randomizations of previously published morphological data for 2Expand
