Increased Abundance Of The Common Raven Within The Ranges Of Greater And Gunnison Sage-Grouse: Influence Of Anthropogenic Subsidies And Fire, Jonathan B. Dinkins, Lindsey R. Perry, Jeffrey L. Beck, Jimmy D. Taylor Jan 2021

Increased Abundance Of The Common Raven Within The Ranges Of Greater And Gunnison Sage-Grouse: Influence Of Anthropogenic Subsidies And Fire, Jonathan B. Dinkins, Lindsey R. Perry, Jeffrey L. Beck, Jimmy D. Taylor

USDA Wildlife Services: Staff Publications

The common raven (Corvus corax; raven) is native to North America and has increased in abundance, especially throughout western North America, during the last century. Human subsidies have facilitated raven dispersal into less suitable habitats and enabled these populations to maintain higher annual survival and reproduction. Concomitantly, overabundant raven populations are impacting other native at-risk species such as the greater sage-grouse (Centrocercus urophasianus) and potentially the Gunnison sage-grouse (C. minimus). Using Breeding Bird Survey data from 1995–2014, we evaluated raven count data to quantitatively describe changes in abundance and expansion into sagebrush ( …


2008 - Managing An Uncertain Future - Climate Change Adaptation Strategies For California's Water Dec 2018

2008 - Managing An Uncertain Future - Climate Change Adaptation Strategies For California's Water

Miscellaneous Documents and Reports

This report recommends a number of adaptation strategies for California and local water managers to improve their capacity to handle change. Many of the strategies will also help adapt California's water resources to accommodate non-climate demands including a growing population, ecosystem restoration and greater flood protection. Several of the recommendations in this report are ready for immediate adoption, while others need additional public deliberation and development. Some can be implemented using existing resources and authority, while the majority will require new resources, sustained financial investment and significant collaborative effort.

Warming, Competition, And Bromus Tectorum Population Growth Across An Elevation Gradient, Aldo Compagnoni, Peter B. Adler Sep 2014

Warming, Competition, And Bromus Tectorum Population Growth Across An Elevation Gradient, Aldo Compagnoni, Peter B. Adler

Green Canyon Environmental Research Area, Logan Utah

Cheatgrass (Bromus tectorum) is one of the most problematic invasive plant species in North America and climate change threatens to exacerbate its impacts. We conducted a two‐year field experiment to test the effect of warming, competition, and seed source on cheatgrass performance across an elevation gradient in northern Utah. We hypothesized that warming would increase cheatgrass performance, but that warming effects would be limited by competing vegetation and by local adaptation of cheatgrass seed sources. The warming treatment relied on open top chambers, we removed vegetation to assess the effect of competition from neighboring vegetation, and we reciprocally …


Relationships Between Elements Of Leslie Matrices And Future Growth Of The Population, Lorisha Lynn Riley Mar 2014

Relationships Between Elements Of Leslie Matrices And Future Growth Of The Population, Lorisha Lynn Riley

Honors Program Projects

Leslie matrices have been used for years to model and predict the growth of animal populations. Recently, general rules have been applied that can relatively easily determine whether an animal population will grow or decline. My mentor, Dr. Justin Brown and I examine, more specifically, whether there are relationships between certain elements of a population and the dominant eigenvalue, which determines growth. Not only do we consider the general 3x3 Leslie matrix, but also we looked into modified versions for incomplete data and migration models of Leslie matrices. We successfully found several connections within these cases; however, there is much …

Effects Of Forest Fragmentation On Central Amazonian Bird Demography, Jared Desmond Wolfe Jan 2014

Effects Of Forest Fragmentation On Central Amazonian Bird Demography, Jared Desmond Wolfe

LSU Doctoral Dissertations

Avian diversity in degraded fragmented Amazonian landscapes depends on the persistence of species in cleared and disturbed areas. Regenerating forest facilitates bird dispersal within degraded Amazonian landscapes and may tip the balance in favor of persistence in previously depauperate habitat patches. Despite the potential value of Amazonian second growth, we lack comparisons of demography among second growth, continuous forest, forest fragments in regenerating landscapes, and truly isolated fragments. Here, we used point-count and capture data to compare Amazonian bird communities among continuous forest plots, 100 ha forest fragments with adjacent second growth, 100 ha forested islands bounded by water, young …


Nonautonomous Beverton-Holt Equations And The Cushing-Henson Conjectures, Saber Elaydi, Robert J. Sacker Jun 2012

Nonautonomous Beverton-Holt Equations And The Cushing-Henson Conjectures, Saber Elaydi, Robert J. Sacker

Saber Elaydi

In [3] Jim Cushing and Shandelle Henson published two conjectures (see Section 3) related to the Beverton-Holt difference equation (with growth parameter exceeding one), which said that the B-H equation with periodically varying coefficients (a) will have a globally asymptotically stable periodic solution and (b) the average of the state variable along the periodic orbit will be strictly less than the average of the carrying capacities of the individual maps. They had previously [2] proved both statements for period 2.

Agenda: Evolving Regional Frameworks For Ag-To-Urban Water Transfers, University Of Colorado Boulder. Natural Resources Law Center, Western Water Policy Program, Western Water Assessment (Program), Red Lodge Clearinghouse

Evolving Regional Frameworks for Ag-to-Urban Water Transfers (December 11)

The permanent transfer of water from agricultural users to municipalities has become a common feature of water management in several western states. In many cases, these voluntary market‐based transfers provide significant benefits to both the buyers and sellers, but many third parties—including remaining irrigators, rural businesses and communities dependent upon agricultural economies—have been negatively impacted. While some impacts of these so‐called “buy and dry” transfers are largely unavoidable, many can be lessened by temporary arrangements that only shift water to cities in years when municipal supplies are inadequate, such as drought and post‐drought storage recovery, and by consolidating individual farm‐to‐city …
