Ecology Of Rusty Blackbirds Wintering In Louisiana: Seasonal Trends, Flock Composition And Habitat Associations, Emma Elizabeth Deleon

LSU Master's Theses

With an estimated population loss of at least 5% annually and a 100-year history of decline, Rusty Blackbirds (Euphagus carolinus) are one of the fastest declining bird species in North America. Determining cause of decline is important, both for conserving the species and for identifying threats to the wooded wetland ecosystems they use on their boreal breeding-grounds and their wintering-grounds in the southeastern United States. One hypothesis is that loss of wintering ground habitat, possibly in conjunction with competition or disease, is causing Rusty Blackbird decline. To determine contribution of wintering ground conditions, it is important to understand the behaviors …

Scale And Justice In Water Allocation, Marian J. Patrick

Theses: Doctorates and Masters

Water allocation is a fundamental part of water resources management. Water allocation is often a contested process because it involves multiple uses and users of water. Issues of justice arise when resources are, or are perceived to be, in short supply. When water is allocated the rules for the distribution of the resource may result in just outcomes for some stakeholders but may create injustices for other stakeholders. Issues of scale thus form an important component of water allocation. This thesis draws from an amalgam of ideas on justice, scale and water management and aims to present a conceptual framework …

A Comparative Study Of Indigenous People's And Early European Settlers' Usage Of Three Perth Wetlands, Western Australia, 1829-1939, Susan Ujma

Theses: Doctorates and Masters

This study takes as its focus the contrasting manner in which the Nyoongar indigenous people and the early European settlers utilised three wetland environments in southwest Australia over the century between 1829 and 1939. The thesis offers both an ecological and a landscape perspective to changes in the wetlands of Herdsman Lake, Lake Joondalup and Loch McNess. The chain of interconnecting linear lakes provides some of the largest permanent sources of fresh water masses on the Swan Coastal Plain. This thesis acknowledges the importance of the wetland system to the Nyoongar indigenous people.

The aim of this research is to …
