Determining The Physiological And Behavioral Responses To Elevated Salinity In The Freshwater Bivalves, Corbicula Fluminea And Lampsilis Ovata, John W. Roden
Electronic Theses and Dissertations
Salinization has been identified as an increasing threat to freshwater mussel diversity in recent years. Native mussels have been observed to display reduced salinity tolerance in comparison to some invasive bivalve species, but methods by which organismal tolerance is achieved are not well understood. This study was designed to compare the behavioral and physiological responses of the native Lampsilis ovata to that of the invasive Corbicula fluminea. Lampsilis were found to exhibit strong behavioral avoidance to salinity exposure, whereas Corbicula displayed very weak avoidance to comparable salinity concentrations followed by indications of osmotic conformation through physiological mechanisms. Prolonged valve …
Physiological And Behavioral Effects Of Climate Change On Wildlife: An Introduction And Overview, Andy Clarke
Physiological And Behavioral Effects Of Climate Change On Wildlife: An Introduction And Overview, Andy Clarke
Senior Honors Theses
Planetary environmental system changes have been recorded and documented for several decades. Fluctuations that were first noticed in atmospheric carbon-dioxide levels have now extended into global pattern changes. Climatic variations that were initially non-threatening variabilities have since been observed creating significant biological influences. The results and evidence of the effects of worldwide environmental climate change on wildlife and biotic environments are worth examining because of the impacts it has on the planet. These climatic effects extend from changes in distribution and diversity patterns of terrestrial mammals to sea-life impacts and recovery trends. Possible wildlife benefits may include increased humidity and …

The Cardiovascular Response To Acute Hypoxic Conditions In Danio Rerio, Bryce Fetterman
Williams Honors College, Honors Research Projects
There are many fish that can withstand hypoxia levels. One in particular is the zebrafish (Danio rerio). The zebrafish is a small-sized, Cyprinid teleost fish, and has been used in a laboratory setting for many reasons. A few reasons being that they are widely available, easy to care for, and the cost for these fish are very low. There are various reasons why these fish are used as a model. One main reason is because their cardiovascular system is one of the first developing organs. This allows for better resolution when studying the cardiovascular system. The purpose of …
