Human Dimensions Of Woody Encroachment Management In Nebraska, Emily Rowen

School of Natural Resources: Dissertations, Theses, and Student Research

Woody plant encroachment (WPE) is a social-ecological problem that will challenge conservation professionals and agricultural producers to adapt their management strategies. This research first examined WPE from the perspective of individual conservation professionals through an online survey. Conservation professionals’ attitudes about adaptation to vegetation transitions, such as WPE, were of interest because these attitudes are one measure of how prepared this group is to respond to WPE. Hypothesized predictors of adaptation attitude were tested through linear regression modeling. These predictors included ecological change, observation of WPE, or risk perception. It was found that risk perception was the strongest predictor of …

Disturbance Reduces Fungal White-Rot Litter Mat Cover In A Wet Subtropical Forest, D. Jean Lodge, Ashley E. Van Beusekom, Grizelle González, Mareli Sánchez-Julia, Sarah Stankavich

USDA Forest Service / UNL Faculty Publications

Fungi that bind leaf litter into mats and produce white-rot via degradation of lignin and other aromatic compounds influence forest nutrient cycling and soil fertility. Extent of white-rot litter mats formed by basidiomycete fungi in Puerto Rico decreased in response to disturbances—a simulated hurricane treatment executed by canopy trimming and debris addition in 2014, a drought in 2015, a treefall, and two hurricanes 10 days apart in September 2017. Percent fungal litter mat cover ranged from 0.4% after Hurricanes Irma and Maria to a high of 53% in forest with undisturbed canopy prior to the 2017 hurricanes, with means mostly …

Blanding’S Turtle (Emydoidea Blandingii): A Technical Conservation Assessment, Justin D. Congdon, Douglas A. Keinath

USDA Forest Service / UNL Faculty Publications

Blanding’s turtles (Emydoidea blandingii) are secure in Nebraska, and they range from being vulnerable to threatened, or endangered throughout most of the rest of their distribution. In Region 2, they have not been reported from Kansas, they are extremely rare in South Dakota, and they occupy wetlands in the northern half of Nebraska. The largest population known within the range of Blanding’s turtles is at Valentine National Wildlife Refuge, Nebraska.

The core habitat of Blanding’s turtles has an aquatic component that consists of a permanent wetland and a suite of other, usually smaller and more temporary, wetlands such …
