Timing Is Everything: Climate Change Implications For Phenological Events And Reproductive Success In River Herring, Meghna N. Marjadi Aug 2023

Timing Is Everything: Climate Change Implications For Phenological Events And Reproductive Success In River Herring, Meghna N. Marjadi

Doctoral Dissertations

Anadromous river herring (alewife (Alosa pseudoharengus) and blueback herring (Alosa aestivalis)) make annual spring spawning migrations from the ocean to freshwater, where juveniles reside before emigrating to the ocean. Climate change may alter environmental and biological cues that prompt both adult migration and juvenile emigration, with implications for adult spawning success and offspring survival for these imperiled species. Shifts in adult migration have been observed in some rivers, while impacts on reproductive success and juvenile survival remain unknown. Cues for juvenile emigration are poorly understood as they have been explored at limited spatial and temporal scales. …


Analysis Of The Population Structure And Migration Habits Of The Northern Leopard Frog (Lithobates Pipiens) At Midewin National Tallgrass Prairie, Gretchen A. Brinkman May 2023

Analysis Of The Population Structure And Migration Habits Of The Northern Leopard Frog (Lithobates Pipiens) At Midewin National Tallgrass Prairie, Gretchen A. Brinkman

Honors Program Projects

Massive amphibian declines of recent years have pushed researchers to pursue population genetics surveys and assess the status of these essential components of many ecosystems. The Northern Leopard Frog (Lithobates pipiens) has continuously experienced population declines across the continental United States due to a combination of habitat losses and environmental changes. Midewin National Tallgrass Prairie houses a considerable portion of L. pipiens in Illinois, and the two creek watersheds studied within this location provide ideal conditions to support these animals. Because this prairie restoration project is a relatively recent development, further assessments regarding the population structure and degree …
