Rate of global biodiversity loss increased significantly during the 20th century associated with human environmental alterations. Specifically, mismanagement of freshwater resources contributed to historical and contemporary loss of stream-dwelling fish diversity and will likely play a role in determining the persistence of species in the future. We present a mechanistic pathway by which human alteration of streams has caused the decline of a unique reproductive guild of Great Plains stream-dwelling fishes, and suggest how future climate change might exacerbate these declines. Stream fragmentation related to impoundments, diversion dams and stream dewatering are consequences of increasing demand for freshwater resources...

Biodiversity in stream networks is threatened globally by interactions between habitat fragmentation and altered hydrologic regimes. In the Great Plains of North America, stream networks are fragmented by 19,000 anthropogenic barriers, and flow regimes are altered by surface water retention and groundwater extraction. We documented the distribution of anthropogenic barriers and dry stream segments in five basins covering the central Great Plains to assess effects of broad-scale environmental change on stream fish community structure and distribution of reproductive guilds. We used an information theoretic approach to rank competing models in which fragmentation, discharge magnitude, and percentage of time streams...

Populations of lesser prairie-chickens are proposed for listing as threatened or endangered. Lesserprairie-chickens require relatively intact, large grassland dominated habitats for population persistence. Successful conservation efforts require knowledge of potential landscape thresholds and grassland patch configuration affecting lesser prairie-chicken populations. We will use existing population survey, lek location, and data from >700 previously marked lesser prairie-chickens to determine the potential for the presences of large-scale landcover thresholds that influence occupancy and persistence of lesser prairie-chickens as well as testing effects of gradients of grassland composition and configuration within...

The black‐tailed prairie dog (Cynomys ludovicianus) is considered an indicator species for the short grass prairie of North America; however, this species currently occupies an estimated 2% of its original distribution. Persistent and pervasive poisoning, and sylvatic plague have fragmented the remaining populations. It is not well understood how these population fragments are connected in a heterogeneous landscape of land use practices and land cover types, but quantifying population isolation and individual measures of dispersal across the landscape are essential to predicting both the vulnerability of extinction due to stochastic processes and the probability of disease emergence. To better understand how land...

Pilot Aquatic Grassland Prioritization Tool Focused on Topeka Shiner and Cogeners. Objectives: 1) Identify data sets and develop methodology building on existing analyses of priority watersheds and fish habitat selection criteria across grassland ecosystem 2) Assess need and feasibility to develop decision tool for strategically addressing measureable, cross-programmatic conservation aquatic grassland benefits. Programs (Fish Habitat, Fish Passage, Partners and FAC, ES and NWR) and partners (Midwest Landscape Initiative and Great Plains FHP) can use this tool to support decisions for committing resources within and across grassland ecosystems to priority areas with multi-species benefits (initial focus on Topeka...

Within grassland communities of the GPLCC one such key indicator species is the Lesser Prairie-chicken (Tympanuchus pallidinctus). Lesser Prairie-chicken range extends across the southern portion of the GPLCC area throughout Texas, Oklahoma, New Mexico, and Kansas. Lesser Prairie-chickens are a good target species because they are widely distributed across the southern GPLCC, are a species of conservation concern, have large home ranges, and are likely sensitive to anthropogenic disturbances. Similarly, the Greater Prairie-chicken (Tympanuchus cupido), is a species of conservation concern, with large home range, distributed across the northern portion of the GPLCC including portions of Oklahoma, Kansas, Nebraska,...

The Great Plains once encompassed 160 million hectares of grassland in the central United States. In the last several decades, conversion of grassland to urban and agricultural production areas has caused significant increases in runoff and erosion. Past attempts to slow this hydrologic system degradation have shown success, but climate change could once again significantly alter the hydrology. The Intergovernmental Panel on Climate Change (IPCC) studies the state of knowledge pertaining to climate change. The IPCC has developed four possible future scenarios (A1, A2, B1 and B2). The output temperature and precipitation data for Northeast Kansas from fifteen A2 General Circulation Models (GCMs) were analyzed in...

Freshwater systems are critically imperiled and continue to be threatened by human encroachment and water development. The upper Gila River in New Mexico is one of the last unobstructed rivers in the Colorado River basin with a mostly intact native fish fauna, including two federally listed and one state-listed fish species. Kansas State University will develop methodologies or decision support tools to assess or evaluate current or existing resource management practices to learn and adapt to the effects of climate change on fish species. The researchers will investigate how the connectivity of the Gila River habitat impacts the fish population with respect to the behavior of native and non-native species.

Groundwater pumping for irrigated agriculture has depleted regional aquifers that sustain habitat for native fishes in the western Great Plains of North America. Depleted surface stream flow is implicated in the decline of 69% of endemic Great Plains fishes, including conservation priority species such as the Arkansas River shiner Notropis girardi. Species declines are likely to continue as water demands increase. Knowledge of spatial patterns of hydrologic connectivity and rates and magnitude of fragmentation through time will help prioritize areas for native fish conservation. We propose to use groundwater-surface water models to document and map the spatiotemporal distribution of flowing and intermittent stream...

In August 2013, the National Wildlife Federation joined forces with Kansas State University to host the second ever America’s Grasslands Conference - held in Manhattan, Kansas. Only a short drive from the Konza Prairie Biological Station, which just recently celebrated its 40th Birthday, the conference was located in an ideal spot to talk about grassland conservation and the future of grasslands. The conference was attended by around 215 participants from across the country, including a diverse group of researchers, conservationists, ranchers, federal and state policy experts, graduate students, and many others. The conference, which ran from August 12-14, featured over 65 speakers and included a riveting keynote...
