Full life-cycle vulnerability assessments are identifying the effects of climate change on nongame migratory birds that are of conservation concern and breed in the upper Midwest and Great Lakes region. Full life-cycle analyses are critical, as current efforts likely underestimate the vulnerability of migratory land birds due to a focus on assessing only one component of the annual cycle. The approach provides a framework for integrating exposure to climate changes, sensitivity to these changes, and the potential for adaptation in both winter and summer seasons, and accounts for carry-over effects from one season to another. The results of this work will inform regional management by highlighting both local and...

This project addressed regional climate change effects on aquatic food webs in the Great Lakes. We sought insights by examining Lake Erie as a representative system with a high level of anthropogenic impacts, strong nutrient gradients, seasonal hypoxia, and spatial overlap of cold- and cool-water fish guilds. In Lake Erie and in large embayments throughout the Great Lakes basin, this situation is a concern for fishery managers, as climate change may exacerbate hypoxia and reduce habitat volume for some species. We examined fish community composition, fine-scale distribution, prey availability, diets, and biochemical tracers for dominant fishes from study areas with medium-high nutrient levels (mesotrophic, Fairport...

Control of invasive sea lamprey recruitment from tributary streams is a major management objective in the Great Lakes, and benefits from barriers that prevent access to spawning habitat. As society moves toward removal of more tributary barriers due to concerns about native migratory fishes, aging infrastructure, and vulnerability to climate-driven flooding, it is important to assess the costs of alternative options for sea lamprey control. This project is integrating cost estimates for application of a lamprey-specific pesticide into cost-benefit optimization models used to support decisions about barrier removals that maximize restoration of habitat for native species. By integrating lamprey control options...

For management agencies, there is a growing need to understand (1) how climate change affects and will continue to affect wildlife populations of conservation concern, and (2) how the negative Upper Midwest Great Lakes Landscape Conservation Cooperative Request for Funding 2013 demographic effects of climate change can be mitigated through management strategies. Climate Change Vulnerability Assessment (CCVA) integrates available data and scientific understanding in a transparent process, details assumptions and uncertainties, and ultimately projects population-level responses of target species to future climate change. Climate change is already influencing distributions and abundances of species throughout North...

This project will improve tribal and First Nation engagement in cooperative natural resource conservation efforts. Researchers are fostering networking among tribes, First Nations and other relevant partners in the upper Midwest – Great Lakes region, and engaging tribal and First Nation representatives in the development of a set of principles and strategies for their authentic, robust inclusion in regional resource conservation cooperative frameworks. The project is conducting an environmental scan of current climate and landscape change planning initiatives as well as mitigation and resilience-building projects being implemented by tribes and First Nations in the region. The results will lead to broader inclusion...

Water levels in the Great Lakes are fluctuating in ways that we have not seen in the past, with both historically low- and high-water levels occurring in the last decade. Expectations are that larger and more frequent water-level fluctuations will occur in response to climate change. The increased variability in lake levels has implications for the management of invasive plants found in the coastal wetlands that surround the Great Lakes, with some species benefiting from periods of low water levels. Phragmites australis, a prominent invasive grass that disrupts fish and wildlife habitats, thrived during the most recent period of low lake levels. However, periods of high lake levels could provide managers with opportunities...

The Great Lakes Restoration initiative (GLRI) template #77 (Beach Recreation Water Quality) in cooperation with 23 local and state agencies expanded the use of predictive modeling at 45 beaches throughout the Great Lakes (fig 1). Local agencies measure fecal-indicator bacteria such as Escherichia coli (E. coli.) along with easily obtained environmental variables used as surrogates to estimate concentrations of fecal-indicator bacteria through a predictive modeling approach. The predictive modeling is being developed by the use of linear regression and/or partial least-squares techniques. The models use software developed by the U.S. Environmental Protection Agency known as “Virtual Beach”. Each beach model is based...

Description of Work Studies assessing seasonal and spatial changes in digestive enzymes and gill raker morphology in bigheaded carps and native planktivorous fishes have been completed. Results indicate that bigheaded carps feed earlier in the year than native filter-feeding fishes and that certain digestive enzymes present in bigheaded carps are either not present in some native fishes or are much less active in the native species than in bigheaded carps. Results also indicate that the gill raker morphology of bigheaded carps is relatively constant with minimal seasonally or spatially relevant changes unlike that of the native gizzard shad (Dorosoma cepedianum) which had both seasonal and spatially correlated changes...

The study seeks to provide a retrospective analysis of the relationships among bird abundance and distribution and changes in land cover and climate in the upper Midwest and Great Lakes region. The resultant models will be used to provide spatially explicit forecasts of future avian responses. Using data from the North American Breeding Bird Survey (BBS) and a hierarchical modeling framework that accounts for imperfect detection during surveys, species distribution and abundance is estimated. Historic aerial photos are being digitized and classified to measure landscape covariates. Once species-specific relationships between distribution parameters (i.e., occupancy, colonization, extinction) and landscape covariates...

The concept of adaptive management provides a set of good business principles to guide strategic habitat conservation, but these principles are only useful if they are put into practice through a complimentary set of business operations. To that end, if conservation is going to be successful operating at landscape scales, the conservation community must start thinking and functioning like a conservation enterprise. Much more emphasis must be placed on developing and supporting business operations that facilitate the flow of information and other resources at landscape scales. Just like successful national and global businesses, we need to develop an information supply chain to support the communication, coordination,...
