Response of Conifer-Encroached Shrublands in the Great Basin to Prescribed Fire and Mechanical Treatments

Creator:: Miller, Richard F., Ratchford, Jaime, Roundy, Bruce A., Tausch, Robin J., Hulet, April, and Chambers, Jeanne
Abstract:: In response to the recent expansion of piñon and juniper woodlands into sagebrush-steppe communities in the northern Great Basin region, numerous conifer-removal projects have been implemented, primarily to release understory vegetation at sites having a wide range of environmental conditions. Responses to these treatments have varied from successful restoration of...

eDNA as a tool for identifying freshwater species in sustainable forestry: A critical review and potential future applications

Creator:: Coble, Ashley A., Flinders, Camille A., Homyack, Jessica A., Penaluna, Brooke E., Cronn, Richard C., and Weitemier, Kevin
Abstract:: Environmental DNA (eDNA) is an emerging biological monitoring tool that can aid in assessing the effects of forestry and forest manufacturing activities on biota. Monitoring taxa across broad spatial and temporal scales is necessary to ensure forest management and forest manufacturing activities meet their environmental goals of maintaining biodiversity. Our...

Phytochemical, antioxidant and antibacterial potential of Elaeagnus kologa (Schlecht.) leaf

Creator:: Merculieff, Zoe, Ramnath, Shubharani, Sankoli, Seethalakshini Madhukar, Venkataramegowda, Sivaram, Murthy, Ganti S., and Ceballos, Ruben Michael
Abstract:: Objective: To screen different solvent extracts of Elaeagnus kologa (E. kologa) leaf to determine the phytochemicals, potent antioxidant and antibacterial activity to find out the possible source of applied pharmaceutical formulations. Methods: Solvent extracts of leaf material were prepared using the Soxhlet apparatus. A study was performed on antioxidant activity...

Vegetation dynamics at two western New York forests

Creator:: Rhea, Neally
Abstract:: Since the early 1900s, widespread agricultural abandonment has occurred in western New York leading to a general increase in forested areas through old-field succession. Even-aged stands typically follow these large-scale disturbances, resulting in a pattern of development with identifiable stages (Oliver 1980). At each stage, changes in vegetation dynamics encourage...

Is Cover Type Use by Dabbling Ducks at Bald Knob National Wildlife Refuge, Arkansas, Related to Energy Availability?

Creator:: Kreisler, Skye E.
Abstract:: Managers of U. S. Fish and Wildlife Service’s Bald Knob National Wildlife Refuge (Refuge) in central Arkansas want to provide sufficient habitat resources to meet its population objectives for wintering waterfowl. Nutrient reserves acquired during the wintering period appear to support spring migration and subsequent reproductive success for some species,...

A Comparative Analysis of Literature Search Results for Chinook Restoration Project Evaluation Between 2012 and 2022 Western Pacific Studies in California, Oregon, and Washington

Creator:: Clark, Erica Jennifer
Abstract:: Pacific salmon are an integral part of ecosystems, industry, culture, and food source. Rapid declines and extirpation in many populations and species have caught the interest of environmentalists, scientists, recreational anglers, commercial fishers, general public, and economists. Billions of dollars have been spent to restore, return, improve, sustain dwindling populations...

Genetic and morphological evidence suggests cryptic speciation within the Torrent Sculpin, Cottus rhotheus, across the Pacific Northwest

Creator:: Nicholas, Benjamin P.
Abstract:: Dwelling on the bottom of large rivers to high alpine streams, freshwater sculpins (genus Cottus) occur in high densities across the Pacific Northwest, with 21 currently recognized species found in the Pacific Northwest. Sculpin fill many ecological roles, with some species serving as important prey sources, and others competing with...

The Viability of Container-Based Sanitation as a Tool for Sanitation Coverage in Urban Haiti

Creator:: VanRiper, Froggi Ramona
Abstract:: Haiti is far from achieving the UN goal of sanitation access for all; 20% Haitians have no sanitation access, and less than 0.1% of urban excreta is safely managed. Container-Based Sanitation (CBS) may be a key tool for achieving equitable sanitation coverage in Haiti’s cities. CBS is a sanitation strategy...

Reconciling Conflicting Phylogenies in the Origin of Sweet Potato and Dispersal to Polynesia

Creator:: Muñoz-Rodríguez, Pablo, Carruthers, Tom, Wood, John R.I., Williams, Bethany R.M., Weitemier, Kevin, Kronmiller, Brent, Ellis, David, Anglin, Noelle L., Longway, Lucas, Harris, Stephen A., Rausher, Mark D., Kelly, Steven, Liston, Aaron, and Scotland, Robert W.
Abstract:: The sweet potato is one of the world’s most widely consumed crops, yet its evolutionary history is poorly understood. In this paper, we present a comprehensive phylogenetic study of all species closely related to the sweet potato and address several questions pertaining to the sweet potato that remained unanswered. Our...
