The expansion of the wind energy industry has had benefits in terms of increased renewable energy production but has also led to increased mortality of migratory bats due to interactions with wind turbines. A key question that could guide bat-related management activities is identifying the geographic origin of bats killed at wind-energy facilities. Generating this information requires developing new methods for identifying the geographic sources of individual bats. Here we explore the viability of assigning geographic origin using trace element analyses of fur to infer the summer molting location of eastern red bats (Lasiurus borealis). Our approach is based on the idea that the concentration of trace elements in bat fur is related through the food chain to the amount of trace elements present in the soil, which varies across large geographic scales. Specifically, we used inductively coupled plasma–mass spectrometry to determine the concentration of fourteen trace elements in fur of 126 known-origin eastern red bats to generate a basemap for assignment throughout the range of this species in eastern North America. We then compared this map to publicly available soil trace element concentrations for the U.S. and Canada, used a probabilistic framework to generate likelihood-of-origin maps for each bat, and assessed how well trace element profiles predicted the origins of these individuals. Overall, our results suggest that trace elements allow successful assignment of individual bats 80% of the time while reducing probable locations in half. Our study supports the use of trace elements to identify the geographic origin of eastern red and perhaps other migratory bats, particularly when combined with data from other biomarkers such as genetic and stable isotope data.

We used three TM images of Ebinur lake wetland: 1990, 2003 and 2010 (August) as the basis data source, We basing on the Markov transfer matrix to analyze the change in value and its transfer tendency of each land use type, and using Fragstats 3.3 software to analyze spatial and temporal change of landscape pattern of our study area in nearly 20 years.Our results show : (1) The land use change of the Ebinur lake wetland is significant: both cultivated land and residential land have expanded significantly, vegetation degraded, and the lake areas shrinked; (3)During 1990-2010, the number of landscape patches increased, the landscape diversity index and fragmentation index increased too, the shape of landscape patches tend to fragment, and the contagion index also declined constantly, which all indicating a fragment trend of landscape pattern of Ebinur lake wetland.
