An Investigation Of Juvenile Alewife (Alosa Pseudoharengus) Habitat Use And Growth Using Natural Markers, Gregory Norman Labonte Jan 2016

An Investigation Of Juvenile Alewife (Alosa Pseudoharengus) Habitat Use And Growth Using Natural Markers, Gregory Norman Labonte

All Theses & Dissertations

This research attempts to connect patterns in growth and migration of an anadromous species. The goal of this research was to understand habitat movements and growth of juvenile alewives (Alosa pseudoharengus) in the Penobscot Estuary and Bay through the use of otolith microchemistry, otolith growth increments, and a laboratory stable isotope turnover study. Understanding the connection between growth and movement of juvenile alewives may lead to more accurate and sophisticated conservation and restoration methods for anadromous species.

We analyzed counts from the annual Midwinter Bald Eagle Survey to examine state, regional, and national trends in counts of wintering Bald Eagles (Haliaeetus leucocephalus) within the conterminous 48 United States from 1986 to 2010. Using hierarchical mixed model methods, we report trends in counts from 11 729 surveys along 844 routes in 44 states. Nationwide Bald Eagle counts increased 0.6% per yr over the 25-yr period, compared to an estimate of 1.9% per yr from 1986 to 2000. Trend estimates for Bald Eagles were significant (P ≤ 0.05) and positive in the northeastern and northwestern U.S ...

The Biopolitics Of The Border, Etienne S. Benson

Departmental Papers (HSS)

First a story about science. In the early decades of the twentieth century, the British ornithologist Henry Eliot Howard made a remarkable discovery. In a series of books culminating in his Territory in Bird Life of 1920, Howard described the instinct for the possession of "territory" that he had found in warblers and other birds. The drive to claim and defend a clearly bordered portion of the landscape, he argued, was the controlling factor in the birds' social life. Among other things, it regulated which males could breed, kept the population in balance with its resources, determined how the birds ...
