This project investigates how disturbance is used as a tool by managers to improve the quality of grasslands enrolled in the Conservation Reserve Program (CRP). To achieve this aim, we are tracking 1) soil, 2) plant, 3) pollinator, and 4) ground–dwelling macroinvertebrates response to the disturbances used by managers that serve as analogies for historical disturbance.

To determine the distribution of functional groups within and across scales, the association of measures of biotic variability in vertebrates (e.g., invasions, extinctions, nomadism, migration) with discontinuities in body mass distributions, and cross-scale analyses of patterns in body mass distributions from local to hemispheric scales.

This research project focuses on the response of species at risk. Assessment has focused on elements that are likely to respond rapidly, such as vegetation structure (which are directly manipulated in the LIP), insect communities (which have short generation times), and bird communities (which respond to vegetative structure).

To explore the causes and consequences of the generation of novelty and innovation for humans, for social systems and for ecological systems, we will convene a small diverse group of researchers from diverse disciplines, with a variety of approaches and backgrounds, where we believe a deliberate focus on the concept of novelty could be fruitful.

To document potential competition bottlenecks that exist between white perch and other fish species of importance in the hopes of developing a management program to eliminate the "stunted" status for the white perch population in Branched Oak Lake and to prevent stunting of the white perch population in Pawnee Lake.

Throughout the Great Plains, changing land-use practices are resulting in large scale biodiversity loss and an ever increasing dependence on effective conservation and restoration efforts provided by private, state, and federal agencies. Yet, far too often local management efforts fail to demonstrate the desired outcome for wildlife populations.

1. Identify how the social component of ecosystems can be integrated into ecological network analysis (or vice versa); and
2. Apply and adapt the current ecological network analysis approach to predict movement, likelihood of introduction, and establishment of aquatic invasive species.

Current standards for sampling channel catfish in lentic systems often yield inadequate catch to assess populations. The objective of this study was to utilize a recently developed sampling method, tandem-set hoop nets, to collect channel catfish in sufficient quantities to describe the effects of stocking and habitat variability on populations in lentic ecosystems.

The purpose of this project was to gain an understanding of the factors affecting recruitment of walleye and white bass in irrigation reservoirs. The primary foci were to document the relative importance of spawning habitats, and the timing of recruitment bottlenecks for walleye and white bass in southwest Nebraska irrigation reservoirs.

The goal of this research is to provide state furbearer managers with a more complete picture of North American river otter (Lontra canadensis) distribution in the state of Nebraska so that they may be better equipped to make management decisions regarding the conservation status and harvest potential of this species in the state.

Project objectives were to
1) compare the vertebrate body mass structures of Mediterranean-climate ecosystems, and
2) examine the effects of invasions and extinctions in Mediterranean-climate ecosystems on body mass structure and alpha, beta and gamma diversity.
