Effects of chemical contaminants on genetic diversity in natural populations: implications for biomonitoring and ecotoxicology.
The conservation of genetic diversity has emerged as one of the central issues in conservation biology. Although researchers in the areas of evolutionary biology, population management, andExpand

The effects of silver nanoparticles on fathead minnow (Pimephales promelas) embryos
Nanoparticles are being used in many commercial applications. We describe the toxicity of two commercial silver (Ag) nanoparticle (NP) products, NanoAmor and Sigma on Pimephales promelas embryos.Expand

Phylogenetic relationships within the eared seals (Otariidae: Carnivora): implications for the historical biogeography of the family.
Phylogenetic relationships within the family Otariidae were investigated using two regions of the mitochondrial genome. A 360-bp region of the cytochrome b gene was employed for the primaryExpand

Mitochondrial DNA analysis of hybridization between sympatric white-tailed deer and mule deer in west Texas.
Sympatric populations of white-tailed deer and mule deer (Odocoileus virginianus and Odocoileus hemionus, respectively) on a west Texas ranch share a common mitochondrial DNA restriction mapExpand

Assessing substitution patterns, rates and homoplasy at HVRI of Steller sea lions, Eumetopias jubatus
Despite the widely recognized incidence of homoplasy characterizing this region, the hypervariable region I (HVRI) of the mitochondrial control region is one of the most frequently used geneticExpand

  • 1 November 1986
Fixation of centric fusions in natural populations often encounters minimal meiotic problems due to the ability of trivalents to segregate normally; therefore, little sterility barrier is achievedExpand

Discovery of tetraploidy in a mammal
Polyploidy, or having more than a pair of each type of chromosome, is considered to be unlikely in mammals because it would disrupt the mechanism of dosage compensation that normally inactivates oneExpand

Somatic and heritable effects of environmental genotoxins and the emergence of evolutionary toxicology.
The genetic effects of environmental pollutants include mutations in somatic cells or germinal cells that are the direct result of exposure to toxicants. Biomarkers that detect such mutagenic effectsExpand
