Contemporary observations suggest that water may disappear entirely from portions of some North Slope stream-beds during periods of drought or low flow. Climate models project even drier summers in the future. This could pose a problem for migrating fish that must be able to move back and forth from breeding and summer feeding areas to scarce overwintering sites. This work uses the best available long-term hydrologic data set for the North Slope (in the upper Kuparuk River watershed) to develop a model to assess the vulnerability of stream systems to periodic drought, and the vulnerability of migrating fish to a loss of stream connectivity.

Arctic grayling (Thymallus arcticus) have a life-history strategy specifically adapted to the extreme climate of the North. These fish migrate to spawning grounds just after breakup in the spring, then migrate to feeding sites in early summer, and finally in the fall migrate back to their overwintering sites. The Kuparuk River is a perennial stream originating in the northern foothills of the Brooks Range on the North Slope of Alaska. Sections of the Kuparuk are periodically intermittent in that, during low flows in the system, these channel reaches appear dry. The flow varies between surface and subsurface in this permafrost-dominated environment, with subsurface flow being limited to the unfrozen thaw bulb around...

The distribution and abundance of fishes across the Alaska Arctic is not well understood. Better information on fish distribution is needed for habitat assessment and modeling activities and is also important for planning industrial activities. The State of Alaska maintains a fish distribution database for anadromous fish species, however there is currently no analog for resident fish species. The concept behind AquaBase was to fill the information gap for resident fish by design a database that contains information about all fish species. AquaBase does not duplicate information that is already available in other spatial database, but rather ‘rescues’ data from reports that are not readily available.

Researchers from the University of Alaska Fairbanks (UAF) willdevelop a model that examines the relationship betweenmeasured steam flow and surface water connectivity betweensummer feeding and overwintering habitats for fish on theNorth Slope.
Strategic conservation planning for broad, multi-species landscapes benefits from a data-driven approach that emphasizes persistence of all priority species’ populations and utilized landscapes, while simultaneously accounting for human uses. This study presents such an assessment for priority fishes of the Great Plains of the United States. Species distribution models for 28 priority fish species were created and incorporated into a prioritization framework using the open source software Zonation, accounting for species-specific connectivity needs and current fish habitat condition. Multiple additional assessments were then produced that i.) identify distinct species management units based on distance and compositional...

Recent geomorphic changes observed along the Pecos River in east-central New Mexico have prompted concern that quality egg and larval fish retention habitat for the federally listed Pecos bluntnose shiner (Notropis simus pecocensis, hereafter shiner) is declining. The U.S. Fish and Wildlife Service (Service) is interested in evaluating current habitat conditions and projecting future trends by conducting a comprehensive and in-depth study of the Pecos River’s fluvial geomorphology and hydrology. The Service has contracted with Tetra Tech for this study and this report documents the second (Phase II) of three phases of the effort. Additionally, it is anticipated that this study will provide a basis for habitat restoration...

NEAMAP stands for NorthEast Area Monitoring and Assessment Program. NEAMAP was developed to meet the needs of fisheries management and stock assessment activities in the northeastern United States. NEAMAP began in 2006 with a fall pilot survey and in 2008 began conducting both a spring and fall survey. NEAMAP samples from Cape Cod, MA south to Cape Hatteras, NC and targets both juvenile and adult fishes. NEAMAP is an integrated, cooperative state/federal data collection program. Its mission is to facilitate the collection and dissemination of fishery-independent information obtained in the Northeast for use by state and federal fisheries management agencies, the fishing industry (commercial and recreational),...

The potential implications of climate change to fishes in Great Plains rivers and streams could range from drastic shifts in distribution to extirpation. Many lotic systems in the Great Plains are not well suited for direct escape routes for fish to move to more suitable habitats at other latitudes due to the west-east direction of flows rather than north-south. Therefore, we might expect additional climate related stress on fish communities in the Great Plains compared to other regions of North America. Therefore, we will 1) simulate potential water temperature and flow changes within the Great Plains based on extant regional climate models, 2) assess stream connectivity to potential refugia, 3) develop a database...

Recent observations by U.S. Fish and Wildlife Service (Service) personnel have noted a number of changes along the Pecos River in east central New Mexico that may signal a fundamental decline in habitat quality for the federally listed Pecos bluntnose shiner (shiner). To evaluate trends in fluvial geomorphology, and thus shiner habitat conditions, an in-depth and comprehensive study, including system hydrology, is needed. The Service seeks to describe trends of geomorphic change of the Pecos River and determine plausible alternatives for river operations. Study goals include the evaluation of previously collected field data, analysis of geomorphic changes, review of effects of hydrologic and geomorphic change on...
The Gulf Coast Vulnerability Assessment utilized expert opinion that was gathered through the Standardized Index of Vulnerability and Value (SIVVA) tool, which is an Excel-based vulnerability and prioritization tool that enables assessors to provide input in a relatively short time and allows for relatively seamless compilation of results.The vulnerability of each ecosystem and associated species was conducted by subregion, excluding those subregions where the species did not occur in significant numbers. Assessors were asked to evaluate species based on the habitats they use in a particular subregion. Because vulnerability can vary with life-stage for many species, assessors were asked to consider the most vulnerable...

Conceptually, we overlaid down-scaled Global Climate Model data to assess climatic conditions with fish species thermal tolerance data and potential barrier to movement data to predict future fish species distributions and/or identify species that may be vulnerable to climate projections. These species distribution data, of 13 fish species at 3 different time frames, were constructed from species distribution models containing only current, projected 2050, and projected 2099 air temperature (obtained from The Nature Conservancy Climate Wizard tool) and average United States Geological Survey hydrologic unit-8 daily discharge. Average daily discharge was calculated as the average discharge of all streamgages within...

Significant progress has been made toward the recovery of the threatened Apache Trout. Major threats were removed including hybridization, logging, and overharvest. Remaining threats are being managed and are manageable. Partners agree that it is time to evaluate if the Apache Trout still warrants protection under the Endangered Species Act (ESA). The Apache Trout is a “conservation-reliant species,” meaning that it will need continued active population- and threat-management related to predation and competition from nonnative trout species. Therefore, a long-term CMP is essential to analyzing the species’ status relative to potential delisting. An Apache Trout SSA and CMP are both prerequisite documents needed...
