Molecular drive and population differentiation of satellite DNAs in Cyprinodon variegatus
The genome of the Atlantic sheepshead minnow, <u>Cyprinodon variecratus</u> (cyprinodontidae) contains at least two highly repetitive satellite DNA sequences. The major satellite sequence is present at roughly 10<sup>6</sup> copies per haploid genome. The basic repeating unit averages 170 bp in …

Response of CYP1A and VEGF in <i>Cyprinodon variegatus</i> When Exposed to Source/Dispersed Oil and Hypoxia
… the small estuarine fish, Sheepshead minnow (<em>Cyprinodon variegatus</em>). Specifically, I examined the effects of exposure to crude and dispersed oil and hypoxia. I looked for responses using a combination of molecular and ecological endpoints. These stressors were chosen because of the 2010 …

Impacts of Oil Exposure During Early Life Development Stages In Sheepshead Minnows (<i>Cyprinodon variegatus</i>) Under Different Environmental Factors
… with varying environmental stressors on <em>Cyprinodon variegatus</em> survival, gene expression, and genotoxicity.</p> <p>The post-larval developmental stage was the most sensitive early life stage to oil and abiotic stress. Median lethal concentrations during the post-larval exposures …

The toxicity of ammonia to the marine organisms, sheepshead minnow (Cyprinodon variegatus), mysid (Mysidopsis bahia), and grass shrimp (Palaemonetes pugio)
… with one marine fish, the sheepshead minnow (Cyprinodon variegatus), and two marine invertebrates, the mysid (Mysidopsis bahia), and grass shrimp (Palaemonetes pugio). The acute LC 50 and the no-observed-effect-concentration (NOEC) were determined for each organism and compared to data in the …

Phylogeographic structure of the Atlantic pupfish, Cyprinodon variegatus (Cyprinodontidae), along the eastern coast of North America: Evidence from mitochondrial nucleotide sequences
Cyprinodon variegatus is a pupfish that inhabits the Atlantic coast of North America, nearly continuously, from Massachusetts to Belize. This research attempts to resolve the phlylogeography of C. variegatus by investigating the genetic sequence structure of the mitochondrial control region …

Assessing the Live Bait Industry and the Ecological Status of Invasive Cyprinodontiformes (Sheepshead minnow: Cyprinodon variegatus and Gulf killifish: Fundulus grandis) in Texas Streams
… impacts of the sheepshead minnow (<em>C. variegatus</em>) and the gulf killifish (<em>F. grandis</em>). Both species were thought to have been introduced into inland Texas waters via bait-bucket releases and have caused native populations of their inland congeners to decline. While I did …

Analysis of Hybridization Between Native and Invasive Pupfishes (Cyprinodon)
… a decrease in biodiversity may result. <em>Cyprinodon variegatus </em>is an invasive species that has caused devastation to several <em>Cyprinodon </em>species through rapid hybridization and genetic introgression. <em>Cyprinodon rubrofluviatilis </em>is native to the Brazos, Wichita and Red …

Reproductive Isolation and Genetic Divergence in a Young "Species Flock" of Pupfishes (Cyprinodon sp.) from San Salvador Island, Bahamas
… process. A "miniature" species flock of pupfish (Cyprinodon variegatus) discovered in lakes on San Salvador Island, Bahamas has evolved in less than 6 000 years, and is, therefore, important to the study of the pace of evolutionary processes. The San Salvador Island pupfish flock is composed of a …

Phototoxic target lipid model for predicting the toxicity of polycyclic aromatic hydrocarbons and petroleum to aquatic life
… to the Gulf of Mexico, M. beryllina, A. bahia, Cyprinodon variegatus, and Fundulus grandis using natural or simulated solar radiation. For cases in which no phototoxicity was observed, the PTLM predictions are correct in over 70% of the cases (10 out of 14 predictions). When toxicity was …
