Reproductive isolation and genetic differentiation in North American species of Triops (Crustacea: Branchiopoda: Notostraca)
Electrophoretic analysis of 31 populations, ranging from California to Kansas, indicates that the North American tadpole shrimp Triops longicaudatus (LeConte) is actually a mixture of at least twoExpand

Species richness, endemism and ecology of crustacean assemblages in northern California vernal pools
Ephemeral pools occur worldwide, provide habitat for organisms with a variety of life history strategies, and may have served as evolutionary refugia for some taxa since Mesozoic times. Yet, ourExpand

DIFFERENTIAL SELECTION TO AVOID HYBRIDIZATION IN TWO TOAD SPECIES
Abstract.— The fitness consequences of hybridization critically affect the speciation process. When hybridization is costly, selection favors the evolution of prezygotic isolating mechanisms (e.g.,Expand

Factors Affecting the Distribution and Co-Occurrence of Two Southern Californian Anostracans (Branchiopoda), Branchinecta Sandiegonensis and Streptocephalus Woottoni
We address the rol e of temp erature and maturation rate in limiting the distribution and co -o c­ currence of 2 ephemeral pool branchiopods, Branchinecta sandiegon ensis and Streptocephalus wool/aniExpand

Species richness on islands in time: variation in ephemeral pond crustacean communities in relation to habitat duration and size
Ephemeral ponds are doubly insular habitats in that they are discrete in time as well as in space. Predicting species richness based on pond size has been attempted using measures of both spatialExpand

Population genetic structure of a California endemic branchiopod, Branchinecta sandiegonensis
Branchinecta sandiegonensis (Crustacea: Anostraca) is a narrow range endemic fairy shrimp discontinuously distributed in ephemeral pools on coastal mesas in San Diego County, USA. Ten populationsExpand

LANDSCAPE HOMOGENIZATION THREATENS THE GENETIC INTEGRITY OF THE ENDANGERED SAN DIEGO FAIRY SHRIMP BRANCHINECTA SANDIEGONENSIS (BRANCHIOPODA: ANOSTRACA)
Genetic threats to the integrity and persistence of endangered species can be significant and develop rapidly. These threats include the breakdown of locally adapted gene pools, and more extremeExpand

Cyst bank life-history model for a fairy shrimp from ephemeral ponds
SUMMARY 1. Ephemeral wetland habitats provide a useful model system for studying how lifehistory patterns enable populations to persist despite high environmental variation. One importantExpand

Post-Mating Selection of Hybrid Toads ( Scaphiopus multiplicatus and Scaphiopus bombifrons )
-High frequencies of F I hybrids and the offspring of backcrosses occur in a hybrid zone between the spadefoot toads Scaphiopus multiplicatus and S. bombifrons in southeastern Arizona. To assessExpand
