Human–Wildlife Interactions
Some avian species have developed the capacity to leverage resource subsidies associated with human manipulated landscapes to increase population densities in habitats with naturally low carrying capacities. Elevated corvid densities and new territory establishment have led to an unsustainable increase in depredation pressure on sympatric native wildlife prey populations as well as in crop damage. Yet, subsidized predator removal programs aimed at reducing densities are likely most effective longer-term when conducted in tandem with subsidy control, habitat management, and robust assessment monitoring programs. We developed decision support software that leverages stage structured Lefkovitch population matrices to compare and identify treatment …

Animals are considered to possess personalities when individuals differ in behavior, and these differences are consistent between situations. Several studies have identified personalities in diverse groups but less is known about personality variation between the sexes. In this study, we examined variation in two key personality traits (boldness, activity) in female and male purple marsh crabs (Sesarma reticulatum) using a semi-field approach. Specifically, we measured boldness and activity on two consecutive days using the same behavioral assays during each time point. Consistency (personality) was determined using Kendall’s coefficient of concordance based on Spearman correlation coefficients for each behavior. …

The Three Creeks Allotment Consolidation: Changing Western Federal Grazing Paradigms, Taylor Payne
Human–Wildlife Interactions
The federal government owns approximately 47% of all land in the western United States. In the state of Utah, about 64% of the land base is managed by the federal Bureau of Land Management (BLM) and the U.S. Forest Service (USFS). The government has historically issued permits to owners of private lands to allow the owners to graze their livestock on public lands. The permits (allotments) are generally of 10-year duration and allow for an annual season of use. In some cases, continued and repeated historical annual grazing practices may not be ideal for permit holders and their communities nor …

1080 : A Selective Poison For Pests, D R. King
1080 : A Selective Poison For Pests, D R. King
Journal of the Department of Agriculture, Western Australia, Series 4
Since the 1960s, the control programmes for rabbits and dingoes in Western Australia have relied heavily on the use of sodium monofluoroacetate, more commonly known as compound 1080. Large quantaties are used each year as it is a valuable substance for the control of vertebrate pests.
Once in the animal's body 1080 is converted to fluorocitrate, a poison which is highly toxic to most mammals. Fluorocitrate blocks the Krebs cycle, a fundamental pathway of energy exchange in animals and plants. The animal dies as a result of damage to the heart, or to the brain and central nervous system, or …
