Climate change is influencing temperature, precipitation, and the temporal availability of resources required for successful reproduction and survival. Implications for the economically and culturally important eastern wild turkey (Meleagris gallopavo silvestris) are largely unknown. Therefore, we assessed associations between observed weather and eastern wild turkey nest initiation timing and nest survival and then projected observed associations under multiple climate change scenarios to assess potential implications of future climate change. Nest initiation date was influenced by temperature and precipitation, but projected changes associated with climate change shift nest initiation date by <0.1 day by 2041-2060....

Climate change has been shown to influence lake temperatures globally. To better understand the diversity of lake responses to climate change and give managers tools to manage individual lakes, we modelled daily water temperature profiles for 10,774 lakes in Michigan, Minnesota and Wisconsin for contemporary (1979-2015) and future (2020-2040 and 2080-2100) time periods with climate models based on the Representative Concentration Pathway 8.5, the worst-case emission scenario. From simulated temperatures, we derived commonly used, ecologically relevant annual metrics of thermal conditions for each lake. We included all available supporting metadata including satellite and in-situ observations of water clarity, maximum...
Highlights Multiple fingerprints built using four-part conservativeness tests and random forest. Floodplain sediment on which extensive cottonwood groves established dates to 1912. The source for ∼85% of this sediment are tributaries that were eroding at that time. Random forest can improve tracer selection in fingerprinting approaches. Findings underscore the major role of tributaries in the dynamics of large rivers. Abstract Sediment deposition on floodplains is essential for the development and maintenance of riparian ecosystems. Upstream erosion is known to influence downstream floodplain construction, but linking these disparate processes is challenging, especially over large spatial and temporal scales....

Integrating climate change into place-based conservation presents a pressing challenge for promoting future biodiversity conservation success. In particular, the broad effects of climate change can make it difficult to prioritize specific actions in specific places. Natural Heritage New Mexico, along with state and federal partners, has developed Conservation Opportunity Areas (COAs) for New Mexico representing locations where limited conservation funds can be effectively used for preserving sensitive species (COAs include Important Plant Areas). Although the COAs currently represent our best estimate of where conservation activities are most likely to have favorable outcomes, they do not account for climate change...
