Cnh: Fine-Scale Dynamics Of Human Adaptation In Coupled Natural And Social Systems: An Integrated Computational Approach Applied To Three Fisheries, James A. Wilson, James Acheson, Robert Steneck, Yong Chen, Teresa R. Johnson

University of Maine Office of Research Administration: Grant Reports

The purpose of this project is to gain a better understanding of the way competition between individual fishermen lead to the emergence of private incentives and informal social arrangements that are (or are not) consistent with conservation of the resource. These informal arrangements and incentives are important because they help us understand the extent to which private interests might strengthen or weaken on-going resource management and, consequently, the sustainability of coupled human and natural systems. The broad hypothesis driving the study is that the informal social structure that emerges from competitive interactions among fishermen reflects the particular circumstances of the …

Phenology And Effects Of Dams On The Success Of Atlantic Salmon Smolt Migrations In The Penobscot River, Maine, Daniel S. Stich

Electronic Theses and Dissertations

Atlantic salmon Salmo salar populations are diminished throughout their range and high marine mortality is among the drivers of the failure of many stocks to recover. A goal of salmon recovery is to maximize the number of juvenile ‘smolts’ entering the ocean to offset loss therein. Dam removals and changes to hydropower allocation in Maine’s largest river, the Penobscot River, have occurred as part of the Penobscot River Restoration Project (PRRP). These activities, in addition to stocking have the potential to influence the number of smolts reaching the ocean. Telemetry was used to investigate factors influencing initiation of migratory behavior, …

Objective IV: Publish and disseminate new and expanded data in the Maine Geological Survey’s biannual State o f Maine’s Beaches reports in 2013 and 2015.

Habitat Occupancy Of Rusty Blackbirds (Euphagus Carolinus) Breeding In Northern New England, Usa, Luke L. Powell, Thomas P. Hodgman, Ian J. Fiske, William E. Glanz

Biology and Ecology Faculty Scholarship

The Rusty Blackbird (Euphagus carolinus), an uncommon songbird often associated with northern coniferous wetlands, has experienced a precipitous population decline since at least the early 20th century. Here, we provide the first analysis of breeding-habitat occupancy at the wetland scale and make recommendations for streamlined monitoring. We modeled occupancy and detectability as a function of site (i.e. habitat-based) and sampling (i.e. visit-specific) variables collected at 546 wetlands in northern New England, USA. Wetland occupancy (mean 6 SE ¼ 0.07 6 0.02 in randomly selected wetlands, and 0.12 6 0.02 in all wetlands surveyed) was best explained by variables …

Ecology Of The Bay / Écologie De La Baie, Downeast Fisheries Trail, Roosevelt-Campobello International Park

Maine Sea Grant Publications

At the mouth of the St. Croix River, Passamaquoddy Bay lies along the border of Downeast Maine and coastal Charlotte County, New Brunswick.

Passamaquoddy Bay is influenced by the extreme twice-daily tides and strong currents that bring nutrients from the deep ocean into the Bay of Fundy, creating a rich feeding ground for fin, minke, and humpback whales, and the endangered North Atlantic right whale.
