Assessing Lipid Content In Migrating Alewife, Anthony Zenga
Assessing Lipid Content In Migrating Alewife, Anthony Zenga
Honors College
Alewife are a commercially, economically, and ecologically important fish, that expend large amounts of energy during their long migrations to spawning habitat. This energy demand can influence an individual’s chances of surviving and reproducing successfully. To understand how energy use may affect fitness, we captured alewife from the Souadabscook Stream over the course of their spawning migration. Fifty fish were sampled each week from May 12th to June 10th 2019. The lipid content of each individual was measured by using i) a Distell Fatmeter and ii) gravimetric analysis by measuring muscle moisture as an indirect method to assess lipid content. …
Using Passive Acoustic Monitoring To Determine Temporal Patters And Mixed Species Flocking Associations Of Migrating North American Warblers In The Gulf Of Maine, David Bridges
Honors College
Recent development of plans for offshore and land-based wind energy projects has created the need for a better understanding of migration in the Gulf of Maine region, an important flyway for countless migrant birds each year. To better understand migration in this region, the University of Maine’s Lab of Avian Biology, working in collaboration with the U.S. Fish and Wildlife Service, deployed acoustic recording units at various sites throughout the Gulf of Maine to detect and quantify flight calls of nocturnally migrating songbirds. Using these data from selected nights, the detected flight call temporal patterns of American Redstarts (Setophaga ruticilla), …
