Inheritance Of Trunk Banding In The Tetra (Gymnocorymbus Ternetzi Characidae), Jack Frankel
Inheritance Of Trunk Banding In The Tetra (Gymnocorymbus Ternetzi Characidae), Jack Frankel
Department of Biology Faculty Publications
The tetra (Gymnocorymbus ternetzi) exhibits two phenotypes associated with trunk banding. Fish possess either a smoky-gray coloration with two prominent black vertical bands located directly behind the operculum (black tetra) or a lighter coloration and lack these bands (white skirt tetra). Segregation patterns observed from the progenies of 11 different crosses suggest that the inheritance of these phenotypes is controlled by two autosomal loci acting in a complementary fashion, with dominance at both loci required for the expression of the darker, banded phenotype.

Demographics And The Ecological Role Of The Channel Catfish (Ictalurus Punctatus) In Commercially Exploited And Unexploited Reaches Of The Wabash River With Implications For The Flathead Catfish (Pylodictis Olivaris), Robert E. Colombo
Robert E. Colombo
Catfish are a major component of the Wabash River fish assemblage and are commercially fished below river kilometer (Rkm) 500. From Rkm 322 through 499 the commercial fishery is subjected only to Indiana fishing regulations. In this reach of river, there is a 254-mm minimum total length limit on both sport and commercially harvested catfish. Below RM 322, the Wabash River forms the state boundary of Indiana and Illinois. In this region of river there are two different length limits on commercially harvested catfish with Indiana having a 254-mm length limit and Illinois having a 381-mm length limit. There is …
Use Of An Artificial Pond And Marshes By Amphibians And Reptiles In West Virginia, Vanessa A. Dozeman
Use Of An Artificial Pond And Marshes By Amphibians And Reptiles In West Virginia, Vanessa A. Dozeman
Theses, Dissertations and Capstones
A farm pond approximately 40 years old located in Wayne County, West Virginia was studied to determine the ingress and egress of amphibians and reptiles. In addition to the pond, 2 small marshes were also examined. The study extended from February 2003 to November 2003. The pond is approximately 36 m long and 38 m wide and is located on a south-facing hillside at 202 m in elevation. A drift fence composed of landscaping cloth was constructed to completely encircle the site. At every 5.15 m, funnel traps were positioned on both sides of the fence. Traps were checked daily …

In an era when sports numbers shatter historical ceilings (especially in baseball) and fall by the wayside like fall leaves, a most enduring record of life continues to crawl along emerging from the sea early each spring pronouncing their incredible "record" of existences... over 350 million years. Now there is a number that even the rarified air of baseball salaries can admire. Yet, today the remarkable sea creature which endured over 100 million years of dramatically changing earth history prior to the existence of the dinosaurs, and which is comprised of only four species globally, is being tested for its …

Over the last decade, research has examined the endocrine-disrupting action of various environmental pollutants, including hormones, pharmaceuticals, and surfactants, in sewage treatment plant effluent. Responding to the growth of concentrated animal feeding operations (CAFOs) and the pollutants present in their wastewater (e.g., nutrients, pharmaceuticals, and hormones), the U.S. Environmental Protection Agency developed a new rule that tightens the regulation of CAFOs. In this study, we collected wild fathead minnows (Pimephales promelas) exposed to feedlot effluent (FLE) and observed significant alterations in their reproductive biology. Male fish were demasculinized (having lower testicular testosterone synthesis, altered head morphometrics, and smaller …
