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...
