An Evaluation Of College Preparedness On Natural Selection Principles Following The Completion Of An Entry-Level Biology Course, Amy Bell

Murray State Theses and Dissertations

Abstract

Evolution education in secondary education has long been a topic of research. The level of knowledge and acceptance of students upon entering college has been studied using various methods; however, no study had provided the perception of preparedness from the student perspective nor had analyzed the individual Natural Selection principles. This study analyzed college freshmen (n=162) in an entry-level BIO 101 course. Participants were given the Conceptual Inventory of Natural Selection Instrument (CINSI) and perception survey questions upon completion of the course. The CINSI data was then analyzed for each of the four Natural Selection principles as well as …

Dirofilaria Immitis Prevalence In Canis Latrans In Kentucky, Melanie Ann Brandon

Murray State Theses and Dissertations

Dirofilaria immitis (canine heartworm) was found in forty-two (42) of the two hundred seventy-five (275) Canis latrans (coyote) necropsied in the state of Kentucky from November 27, 2019 through March 3, 2021. Thirty-five (35) of the positive cases were from western Kentucky region with the other seven spread across the state. With this group of coyotes, one hundred fifty-eight (158) were male and the other one hundred six-teen (116) were female. The estimated age ranged from a pup to senior dogs. A little over forty percent of the dogs were obtained through coyote/predator tournaments; the remaining were acquired from pest …

Males Of The Wolf Spider Rabidosa Rabida Use Two Mechanisms To Stun Females During Copulation, Daniel Schoenberg

Murray State Theses and Dissertations

The differences in energetic input between the sexes required to produce gametes translates to the differences in reproductive behavior and overall mating systems seen in a species. Females generally produce a few energetically and resource expensive eggs and typically choose a high-quality suitor to ensure she has high quality offspring. In contrast, males produce abundant energetically cheap sperm and attempt to fertilize as many eggs as possible in as many females as possible. Both sexes are trying to maximize their inclusive fitness, but the dichotomy of interests can lead to sexual conflict and perhaps extreme or unusual behaviors such as …

Monitoring Relationships Between Corticosterone And Snake Fungal Disease In Timber Rattlesnakes (Crotalus Horridus) In Western Kentucky, John Bromley Hewlett

Murray State Theses and Dissertations

Over the past four decades, emergent fungal diseases have been the most devastating relative to species declines and extinctions. While most research has focused on fungal diseases affecting amphibians and bats, less has focused on diseases like snake fungal disease (SFD), caused by Ophidiomyces ophiodiicola (Oo). SFD was first described in 2006 in North America within a Timber rattlesnake (Crotalus horridus) population in New Hampshire. Since then SFD has been documented in 19 US states, one US territory (Puerto Rico), and Europe. SFD causes high mortality in some species, including the Eastern Massasauga rattlesnakes (Sistrurus …
