Applying Circuit Theory To Describe Changes In Structural Landscape Connectivity In Response To Wildfire, Christian Ross Nielsen
School of Natural Resources: Dissertations, Theses, and Student Research
Understanding and conserving ecological connectivity is critical to the preservation of vulnerable landscapes. Circuit theory, in which landscapes are imagined as circuit boards with varying resistances to the flow of current, is being increasingly used to model spatially explicit connectivity of landscapes and to inform land management and conservation decision-making. Utilizing continuous, quantitative estimates of percent cover by five land cover functional groups to create a conductance surface, this study expanded upon an established application of circuit theory that used the open-source software Circuitscape to model species-agnostic, omnidirectional connectivity. This model was automated using Python to create time-series connectivity maps …

Spatiotemporal Plasticity In Reproductive Readiness And Recruitment Of Ichthyoplankton Of Invasive Silver Carp Along A Western Invasion Front, Jessi L. Urichich
Spatiotemporal Plasticity In Reproductive Readiness And Recruitment Of Ichthyoplankton Of Invasive Silver Carp Along A Western Invasion Front, Jessi L. Urichich
School of Natural Resources: Dissertations, Theses, and Student Research
Individuals of invasive species at the edge of their invasion distribution may exhibit enhanced reproductive capacity and phenotypic plasticity leading to accelerated range expansion. Environmental conditions in highly fluctuating environments at distribution edges may either promote or hinder such reproductive readiness and phenotypic plasticity. Dynamic habitat conditions and periodic disturbances experienced in prairie streams, such as drought (e.g., low-flow, high water temperatures), may potentially reduce suitable spawning environments and ichthyoplankton recruitment of invasive Silver Carp, potentially slowing range expansion or enabling management strategies that reduce abundance in the absence of a reproducing population.

Assessing, Restoring, And Centering Social–Ecological Relationships For Advancing Social–Ecological Resilience In The Northern Great Plains Grasslands, Katia Pilar Carranza Bernal
School of Natural Resources: Dissertations, Theses, and Student Research
The Northern Great Plains grasslands are social-ecological systems that were shaped by evolutionary and Indigenous social-ecological relationships. European colonization disrupted many of these interactions, including the coupling of fire and grazing, and degraded social-ecological resilience, shifting these grasslands to a new state. For those reasons, my research focused on assessing, restoring, and centering evolutionary and Indigenous social-ecological relationships for advancing social-ecological resilience in the Northern Great Plains grasslands. I first performed a study in the Nebraska Sandhillls assessing the potential of patch-burn grazing to support grassland resilience by comparing its effects to those of rotational grazing. Through vegetation and bird …
Caught On Camera: Evaluating Wood Duck (Aix Sponsa) Cavity Occurrence And Trapping Efficiency, Cindy L. Von Haugg
Caught On Camera: Evaluating Wood Duck (Aix Sponsa) Cavity Occurrence And Trapping Efficiency, Cindy L. Von Haugg
All Theses
Wood ducks (Aix sponsa) garner significant ecologic and economic importance as the second most harvested waterfowl species in two of the four migratory flyways in North America, but the accuracy of population monitoring, relative to other duck species, is stifled by the wood duck’s secretive nature and nesting habitat. As an alternate, population models would improve current assessments, but more data on the demographic vital rates of cavity-nesting wood ducks is needed. I aimed to help bridge this knowledge gap by developing a method to increase data collection efficiency, and with it, accomplish two objectives: 1) Calculate the relative abundance …
