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...

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...

We used the United States National Grid to develop a sampling grid for monitoring programs in the Great Plains Landscape Conservation Cooperative, delineated by Bird Conservation Regions 18 and 19. Landscape Conservation Cooperatives are science based partnerships with the goal to inform and guide conservation at regional landscape levels. Developing a standardized sampling grid for a LCC is a new endeavor and is designed to reduce program costs, avoid repetition in sampling, and increase efficiency in monitoring programs. This is possible because the grid’s nationwide coverage, uniform starting point, and scalability allow researchers to expand their monitoring programs from a small, local level to a regional or...

Sediment accumulation in playa wetlands, such as those in the Rainwater Basin in south-central Nebraska, reduces the hydrologic functionality and alters the vegetative composition of the wetlands reducing their ability to provide forage and resting habitat for migratory birds. Most Rainwater Basin wetlands have intense agricultural production occuring within their watersheds that accelerate sediment accumulation within the wetland. This sediment accumulation reduced the abilty of the wetland to hold water which, in turn, allows invasive and upland plants to proliferate with the wetland footprint. Planting upland grassland buffers around wetlands reduces the sediment load entering the wetland reducing the need...

In June 2015, the Eastern Tallgrass Prairie and Big Rivers Landscape Conservation Cooperative (LCC) of the U.S. Fish & Wildlife Service (USFWS) granted $80,000 to the City of St. Louis (City) to promote urban monarch conservation by expanding activities associated with Milkweeds for Monarchs: The St. Louis Butterfly Project (M4M). Generally speaking, the USFWS grant was to: (1) enhance urban education and outreach efforts, and (2) conduct research on urban monarch habitat. The project spent $51,583.57 on activities for ed and $27,785.68 for research. The City’s Office of the Mayor used a portion of the funds to contract a part time individual to act as a Monarch Community Liaison, and used the majority of the grant...

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...

Habitat loss and fragmentation are widely recognized as among the most important threats to global biodiversity. New analytical approaches are providing improved ability to predict the effects of landscape change on population connectivity at vast spatial extents. This paper presents an analysis of population connectivity for three species of conservation concern [swift fox (Vulpes velox); lesser prairie-chicken (Tympanuchus pallidicinctus); massasuaga (Sistrurus catenatus)] across the American Great Plains region. We used factorial least-cost path and resistant kernel analyses to predict effects of landscape conditions on corridor network connectivity. Our predictions of population connectivity provide testable...

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 range-wide plan (RWP) has been developed in response to concerns about lesser prairie-chicken (LPC) habitat threats which may be impacting LPC populations, and the proposed listing under the Endangered Species Act (ESA). Along with the existing conservation efforts already being implemented, as described in the RWP, the supporting WAFWA Conservation Agreement (WCA) represents another mechanism to implement conservation to benefit LPC. The WCP represents an opportunity to enroll participants who agree to avoid, minimize and mitigate actions which may be detrimental to LPC. Landowners may enroll properties to be managed for the benefit of LPC. Properties may generate credits for mitigation. When complete avoidance...

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...

Species populations are in a state of flux due to the cumulative and interacting impacts of climate change and human stressors across landscapes. Invasive spread, pathogen outbreaks, land-use activities, and especially climate disruption and its associated impacts—severe drought (see Figure 3 or the GPLCC), reduced stream flow, increased wildfire frequency, extended growing season, and extreme weather events—are increasing, and in some cases accelerating. These impacts are outpacing management and conservation responses intended to support trust species and their critical habitats. Our common goal is to craft successful adaptation strategies in the face of these multiple, interacting drivers of environmental change....

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...
