Analysis of molecular variance inferred from metric distances among DNA haplotypes: application to human mitochondrial DNA restriction data.
We present here a framework for the study of molecular variation within a single species. Information on DNA haplotype divergence is incorporated into an analysis of variance format, derived from aExpand

Universal cytochrome b primers facilitate intraspecific studies in molluscan taxa.
We describe the construction of amplification primers designed to target a portion of the mitochondrial cytochrome b locus in a variety of molluscan taxa. Combinations of two sets of primersExpand

Genetic evidence of cryptic speciation within hammerhead sharks (Genus Sphyrna)
Surveys of genetic variation within cosmopolitan marine species often uncover deep divergences, indicating historical separation and potentially cryptic speciation. Based on broad geographic (coastalExpand

Molecular Analysis of Diazotroph Diversity in the Rhizosphere of the Smooth Cordgrass, Spartina alterniflora
ABSTRACT N2 fixation by diazotrophic bacteria associated with the roots of the smooth cordgrass, Spartina alterniflora, is an important source of new nitrogen in many salt marsh ecosystems. However,Expand

POPULATION DIFFERENTIATION DECREASES WITH DEPTH IN DEEP‐SEA BIVALVES
Abstract The deep sea is the largest ecosystem on Earth. Recent exploration has revealed that it supports a highly diverse and endemic benthic invertebrate fauna, yet the evolutionary processes thatExpand

Fitness differences among remnant populations of the endangered sonoran topminnow.
Four correlates of fitness were measured in three stocks of the endangered Sonoran topminnow, Poeciliopsis occidentalis, from Arizona. Survival, growth, early fecundity, and developmental stabilityExpand

Analyses of Nuclear ldhA Gene and mtDNA Control Region Sequences of Atlantic Northern Bluefin Tuna Populations
There has been considerable debate about whether the Atlantic northern bluefin tuna exist as a single panmictic unit. We have addressed this issue by examining both mitochondrial DNA control regionExpand

Highly polymorphic microsatellite loci in the colonial ascidian Botryllus schlosseri.
Five mircosatellite loci are characterized for the colonial ascidian Botryllus schlosseri. Within one population from Monterey, California, these loci have 3 to 17 alleles, observed heterozygositiesExpand

Bathymetric patterns of genetic variation in a deep-sea protobranch bivalve, Deminucula atacellana
Abstract The origin of the deep-sea benthic fauna is poorly understood and represents an enormous gap in our understanding of basic evolutionary phenomena. One obstacle to studying evolutionaryExpand

Observations of a Feeding Aggregation of Whale Sharks, Rhincodon typus, in the North Central Gulf of Mexico
On 26 June 2006 an aggregation of 16 whale sharks was observed for a period of 4 hr in the north central Gulf of Mexico (GOM). The sharks remained within an area about 1.0 km 2 in size andExpand
