Analysis of molecular variance inferred from metric distances among DNA haplotypes: application to human mitochondrial DNA restriction data.
Application of AMOVA to human mitochondrial DNA haplotype data shows that population subdivisions are better resolved when some measure of molecular differences among haplotypes is introduced into the analysis, and Monte Carlo studies show that site sampling does not fundamentally affect the significance of the molecular variance components.
Genetic evidence of cryptic speciation within hammerhead sharks (Genus Sphyrna)
Effective management of large coastal shark species should incorporate this important discovery and the inference from sampling that the cryptic scalloped hammerhead is less abundant than S. lewini, making it potentially more susceptible to fishery pressure.
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 to emphasize the need for genetic as well as demographic information for the development of comprehensive species recovery programs.

The construction of amplification primers designed to target a portion of the mitochondrial cytochrome b locus in a variety of molluscan taxa are described and the utility of these primer sets for studies of intraspecific phylogeny inmollusks and potentially other invertebrates is discussed.

It is suggested that the steep, topographically complex, and dynamic bathyal zone, which stretches as a narrow band along continental margins, plays a more important role in the evolutionary radiation of the deep‐sea fauna than the much more extensive abyss.
Distributional patterns of adult male loggerhead sea turtles (Caretta caretta) in the vicinity of Cape Canaveral, Florida, USA during and after a major annual breeding aggregation
Cluster analysis revealed the strongest association for dive duration with sea state during and after the breeding period, with significantly longer dives during more turbulent conditions, and univariate associations with surface interval duration were not elucidated.

Five mircosatellite loci are characterized for the colonial ascidian Botryllus schlosseri and demonstrate Mendelian patterns of inheritance in laboratory crosses, suggesting that most allelic diversity within these loci is generated by single-step and less frequently multistep mutations.
Bathymetric patterns of genetic variation in a deep-sea protobranch bivalve, Deminucula atacellana
This surprisingly high biodiversity at the genetic level affords the potential for adaptation and evolutionary diversification, the ultimate historical causes of high species diversity in the deep-sea benthos.
Observations of a Feeding Aggregation of Whale Sharks, Rhincodon typus, in the North Central Gulf of Mexico
The observed feed- ing behavior and the abundance of fish eggs at the study site indicated the whale sharks were feeding on recently spawned little tunny eggs, the first confirmed observation of a feeding aggregation of whale sharks in the GOM.
