Download or read book Assessing Facilitated Passage and Spawning Migration Patterns of Razorback Suckers Xyrauchen Texanus in the San Juan River written by Matthew R. Bogaard and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the southwestern United States, decades of water diversions, construction of large impoundments, and loss of floodplain habitats have all contributed to a highly fragmented riverine landscape. River regulation, through damming, alters the magnitude and timing of discharge and temperature regimes and interrupts nutrient and sediment transport. Additionally, barriers negatively affect vital rates of riverine fish populations that rely on connected migratory routes to complete components of their life cycle, such as spawning migrations. A capture-translocation strategy has been implemented for Razorback Suckers, Xyrauchen texanus, in the San Juan River to mitigate negative effects of barriers, while precluding passage of nonnative species. We used active and passive radio telemetry to assess Razorback Sucker movements following translocation upstream of two barriers. Furthermore, we used seven years of Passive Integrated Transponder tag detection data at each barrier to test associations of Razorback Sucker occurrence and environmental parameters that may cue spawning migrations. While translocated individuals tended to return downstream of barriers within a year of passage, our results indicated that most individuals (>80%) remained upstream long enough to successfully spawn. Following translocation at each barrier, we observed upstream movements ranging from 2 to 262 km and detected distinct aggregations within the expected spawning season. Timing of putative spawning migrations had strong associations with water temperature, where the largest proportions of Razorback Suckers were first detected at barriers as mean weekly water temperature was increasing between 7.1 to 14.2 °C. Our research provided a model that managers can use to predict the timing of occurrence of migrating Razorback Suckers, serving as a tool to improve efficiency of selective passage facilities by prioritizing passage efforts during times of peak migration. While translocation provides an option of selective passage that may seasonally reconnect migratory routes for a proportion of the population and increase spawning potential, it is not clear if this will be enough to mitigate other recruitment bottlenecks, (e.g., access to predator-free habitats) necessary to recover Razorback Sucker populations.
Download or read book Climate Change in the Great Lakes Region written by Thomas Dietz and published by Michigan State University Press. This book was released on 2011-12-01 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: People living in the Great Lakes region are already feeling the effects of a changing climate. Shifts in seasonal temperatures and precipitation patterns could have dramatic impacts on the economy, ecology, and quality of life. In this illuminating and thorough volume, leading scholars address the challenge of preparing for climate change in the region, where decision makers from various sectors—government, agriculture, recreation, and tourism—must increasingly be aware of the need to incorporate climate change into their short- and long-term planning. The chapters in this revealing book, written by some of the foremost climate change scholars in North America, outline the major trends in the climate of the Great Lakes region, how humans might cope with the uncertainty of climate change impacts, and examples of on-the-ground projects that have addressed these issues.

This book was released on 2000 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Joint Commission established the Indicators Implementation Task Force to assist in implementing integrative indicators of Great Lakes Basin ecosystem integrity. This report reviews activities of the Task Force, including its research of Great Lakes databases, technical reviews, and workshop proceedings. It explains the Task Force relationship with the State of the Lakes Ecosystem Conference (SOLEC), and compares the Task Force proposed suite of indicators with the SOLEC suite with regard to desired outcomes related to swimmability, fishability, drinkability, population health, economic viability, & others. The final section includes recommendations regarding data & information management, implementation & development of indicators, and long-term involvement by the Commission. The appendix reviews other initiatives using environmental indicators.
