Do Marine Protected Areas Affect Emerging Fisheries Population Density?, Jennifer Greene, Katherine O. Grady, Crow White, Danielle Zacherl
Do Marine Protected Areas Affect Emerging Fisheries Population Density?, Jennifer Greene, Katherine O. Grady, Crow White, Danielle Zacherl
STAR Program Research Presentations
Kellet’s whelk, Kelletia kelletii, were observed at sample sites throughout their range from Baja California, Mexico, to Monterey, CA to determine patterns of population density. Sample sites in each region were either located within California marine protected areas where take of the Kellet’s whelk in prohibited, or in non-protected areas where the whelks can be fished both commercially and recreationally. Kellet’s whelk population density was compared between all MPA and non-MPA sample sites. These mean densities were also found for sites in Santa Barbara and San Diego near active fishing ports and compared to data from the same sites collected …
Diel Vertical Migration Of An Invasive Calanoid Copepod, Eurytemora Affinis, In Little Sturgeon Bay, Wisconsin, Alexandra N. Poli
Diel Vertical Migration Of An Invasive Calanoid Copepod, Eurytemora Affinis, In Little Sturgeon Bay, Wisconsin, Alexandra N. Poli
Lawrence University Honors Projects
Eurytemora affinis, a calanoid copepod, is known to be a versatile, prolific invader of freshwater ecosystems across the globe. It has recently been documented in the Laurentian Great Lakes, including in Little Sturgeon Bay, an embayment of Lake Michigan. One survival mechanism that could make E. affinis a successful invader is diel vertical migration (DVM), a behavior in which animals move to different lakes depths at different times of day in order to avoid predation. Much is known about DVM of E. affinis, but primarily from studies in marine and brackish systems. Our goal was to investigate how …
The Characterization Of A Vital Wisconsin Waterway: A Biological Assessment Of The Lower Fox River From 2006-2014, Emily L. Kiehnau
The Characterization Of A Vital Wisconsin Waterway: A Biological Assessment Of The Lower Fox River From 2006-2014, Emily L. Kiehnau
Lawrence University Honors Projects
The Lower Fox River has historically been used as a navigational crossroads, a waste disposal system, and source of hydroelectric power. Over the years, heavy use of the river has negatively affected water quality and the overall health of the system. Unhealthy rivers cannot function properly. Biological assessment based on animal surveys are often used to determine river health. I used data from the Lawrence University and Fox River Navigational System Authority invasive species-monitoring project to explore how the distribution of animals in the Fox River has changed over time and across locations. Monitoring surveys have taken place between June …
