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 Migration Monitoring Data To Assess Bird Population Status And Behavior In A Changing Environment, Evan M. Adams
Using Migration Monitoring Data To Assess Bird Population Status And Behavior In A Changing Environment, Evan M. Adams
Electronic Theses and Dissertations
Across the world, researchers use migration banding stations to document bird migration and study the phenomenon. In this dissertation, I focus on ways of analyzing bird migration banding data and the utility migrating birds as indicators of ecosystem health that make these monitoring efforts more useful to answering ecological questions and managing migratory species. In Chapter 1, we provide background on hierarchical modeling and an overview of our findings. In Chapter 2, we developed and validated new methods to estimate daily changes in migratory population size while controlling for changes in detectability due to environmental conditions. In Chapter 3, this …
