Ash Decline: An Opportunity For Young Forest Wildlife, Bianca Beland

Honors College

The overall decline of ash tree health presents an opportunity for landowners to salvage dying trees, thus contributing to state and federal efforts to create young forest habitat for a wide variety of wildlife species, in addition to benefitting from the financial and recreational opportunities that come following salvage operations. This case study examines the results of a decision made by the Metropolitan District Commission (MDC, Hartford, CT) to conduct a timber salvage operation on its public water supply watershed land to remove dying white ash (Fraxinus americana) trees and at the same time meet the goals of the …

Examining Movement And Habitat Selection Of Everglades Fishes In Response To Seasonal Water Levels, Gregory J. Hill

FIU Electronic Theses and Dissertations

Fish distribution patterns and seasonal habitat use play a key role in the food web dynamics of aquatic ecosystems, including the Florida Everglades. In this study I examined the fine scale habitat shifts and movements of spotted sunfish, Lepomis punctatus across varying seasons and hydrologic conditions using in-situ field enclosures and Passive Integrated Transponder (PIT) systems. Data on fish use of three dominant Everglades marsh habitats and activity level were recorded continuously from January to August, 2015. Fish were more active and had the highest use of higher elevation habitats when water levels rose during an experimental reversal in mid-April. …

The Long Shadow Of Senescence: Age Impacts Survival And Territory Defense In Loons, Walter H. Piper, Kristin M. Brunk, Joel A. Flory, Michael W. Meyer

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Senescence, increased mortality that occurs among animals of advanced age, impacts behavior and ecology in many avian species. We investigated actuarial, reproductive, and behavioral senescence using capture, marking, and resighting data from a 26-year study of common loons (Gavia immer). Territorial residents of both sexes exhibited high annual survival (0.94) until their mid 20s, at which point survival fell to 0.76 and 0.77 in males and females, respectively. Sexual symmetry in actuarial senescence is somewhat surprising in this species, because males make a substantially greater investment in territory defense and chick-rearing and because males engage in lethal contests for territory …

Sandhill And Whooping Cranes, Jeb Barzen, Ken Ballinger

Wildlife Damage Management Technical Series

As sandhill crane populations continue to grow in the United States, so too does crop damage, property damage to homeowners, and the risk of crane collisions with aircraft. Whooping crane populations also continue to grow, but with a global population of about 500 individuals (as of 2017), damage is rare and problems often require different solutions due to the species’ endangered status. The behavioral characteristics and habitat needs of sandhill and whooping cranes set the stage for conflict between these birds and people. Recognizing behavioral differences between territorial and non-territorial cranes greatly improves the effectiveness of any management effort.
