The Effects of Chronic Nitrite Exposure on Tissue Morphology and Physiology in Xiphophorus couchianus
… health and development. Therefore, we used the live-bearing fish species Xiphophorus couchianus as a model organism to better understand the effects of chronic nitrite exposure on tissue physiology, morphology and oxidative stress in live-bearing female fish. We hypothesized that chronic nitrite …

Behavioral and Reproductive Plasticity in Eastern Mosquitofish (Gambusia Holbrooki) in Response to Predatory Cues
… cells and alarm substances. I tested if a live-bearing non-ostariophysan, Gambusia holbrooki, exhibited a similar behavioral response to its injured conspecifics. I also examined the effects of exposure to this and other predatory cues during a single pregnancy cycle. I hypothesized that …

Female preferences, paternity and fitness: A combined morphometric/molecular genetic study on Poecilia latipinna and Poecilia formosa
Mate preferences represent an adaptive choice when costs associated with reproduction can be alleviated through gaining direct or indirect benefits from choosing the better mate. Female poeciliid fishes do show clear mate preferences for certain males although males in this highly promiscuous taxon …
