Stream fragmentation alters the structure of aquatic communities on a global scale, generally through loss of native species. Among riverscapes in the Great Plains of North America, stream fragmentation and hydrologic alteration (flow regulation and dewatering) are implicated in the decline of native fish diversity. This study documents the spatio–temporal distribution of fish reproductive guilds in the fragmented Arkansas and Ninnescah rivers of south-central Kansas using retrospective analyses involving 63 years of fish community data. Pelagic-spawning fishes declined throughout the study area during 1950–2013, including Arkansas River shiner (Notropis girardi) last reported in 1983, plains minnow (Hybognathus...

Habitat fragmentation and flow regulation are significant factors related to the decline and extinction of freshwater biota. Pelagic-broadcast spawning cyprinids require moving water and some length of unfragmented stream to complete their life cycle. However, it is unknown how discharge and habitat features interact at multiple spatial scales to alter the transport of semi-buoyant fish eggs. Our objective was to assess the relationship between downstream drift of semi-buoyant egg surrogates (gellan beads) and discharge and habitat complexity. We quantified transport time of a known quantity of beads using 2–3 sampling devices at each of seven locations on the North Canadian and Canadian rivers. Transport time was...

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...

We propose to use long-term fish-population data from a relict reach of the Pecos River, New Mexico to assess population dynamics of imperiled prairie-river minnows, including Arkansas River shiner. Development of viable management strategies requires basic understanding of population ecology. Rigorous, quantitative ecological methods can be used to analyze continuous, long-term demographic data, but such data are rarely available for imperiled, non-game fishes. Data available for the Pecos River provide a unique opportunity to apply quantitative methods to prairie-river minnow conservation and management. Analyses proposed here would determine (1) whether population regulation is density dependent or flow-regime...

Genetic, demographic, and environmental processes affect natural populations synergistically, and understanding their interplay is crucial for the conservation of biodiversity. Stream fishes in metapopulations are particularly sensitive to habitat fragmentation because persistence depends on dispersal and colonization of new habitat but dispersal is constrained to stream networks. Great Plains streams are increasingly fragmented by water diversion and climate change, threatening connectivity of fish populations in this ecosystem. We used seven microsatellite loci to describe population and landscape genetic patterns across 614 individuals from 12 remaining populations of Arkansas darter ( Etheostoma cragini) in...

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 had...

Potamodromous migrations, those that occur entirely in fresh waters, are made by a variety of minnows (Family Cyprinidae) in, and between, freshwater habitats around the world. These migrations most commonly are undertaken for purposes of breeding, feeding, or occupying specific habitats or refugia. There is a growing body of evidence that potamodromous migrations are undertaken by a number of cyprinids native to larger streams and rivers of the Great Plains region of central USA. Cross et al. (1985) observed that populations of Arkansas River shiner disappeared from large tributaries to the Arkansas River, in Kansas, as a result of dam construction and water withdrawal. They speculated that populations in these...

The Arkansas River Shiner (ARS), Notropis girardi, is a federally threatened minnow that now occurs natively in modest numbers only in the South Canadian River, following decades of range contraction and population losses. The remaining populations are at increasing risk as global change is expected to impact the upper and middle South Canadian River with a rise in temperature as much as 4-6 F and a decrease in precipitation from 10 to 35 % in this century. The primary objective of this project was to evaluate potential effects of habitat and environmental change on Arkansas River shiners by examination of habitat use and availability at several spatial scales using both historical and recently-collected data from...

Across the western Great Plains of North America, groundwater pumping for irrigated agriculture has depleted regional aquifers that sustain stream flow for native fishes. Although declines in Great Plains stream discharge owing to groundwater pumping are widely documented, spatial and temporal patterns in stream intermittency across this broad landscape have yet to be quantified. Successful management of native Great Plains stream fishes into the future will require an explicit understanding of the distribution and abundance of habitats, as well as the connections among those habitats across the region. The goal of this study was to provide critical information and decision-support tools to enhance conservation...

Collections of fishes used for data analyses in the project:Historic and Current Habitat Use by Arkansas River Shiner in the South Canadian River in Central Oklahoma as Affected by River Flow: Predictions for Habitat Under Future Climate Scenarios”. Edie Marsh-Matthews and William J. Matthews. Funded and published by the Great Plains Landscape Conservation Cooperative.Collections were all made by seines of a variety of sizes and mesh widths (details for collections are in the appropriate section of the report). Fishes collected were either identified in the field and released or preserved in the field and returned to the laboratory for identification. Habitat data were recorded for each site at different spatial...

While habitat selection and population estimates are well documented for spring migrating birds in the central Platte River system, little information or monitoring efforts on the North Platte River exist, particularly for the multiple priority bird species known to be present. Most conservation partners deliver habitat programs in the region with limited information and a lack of a landscape prioritization tools. In order for conservation delivery to be more effective and efficient in utilizing limited funds, a decision support tool is critical so that priority species habitat needs are being addressed through appropriate restoration/management strategies in the correct geography at multiple scales. We propose...

We used comparative landscape genetics to examine the relative roles of historical events, intrinsic traits and landscape factors in determining the distribution of genetic diversity of river fishes across the North American Great Plains. Spatial patterns of diversity were overlaid on a patch-based graphical model and then compared within and among three species that co-occurred across five Great Plains watersheds. Species differing in reproductive strategy (benthic vs. pelagic-spawning) were hypothesized to have different patterns of genetic diversity, but the overriding factor shaping contemporary patterns of diversity was the signature of past climates and geological history. Allelic diversity was significantly...
