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.

The aim of the present study was to compare trace element profiles and the differences in uptake and translocation of trace elements in plants from five populations (three from Greece and two from Serbia) belonging to three subspecies of Silene parnassica Boiss. & Sprun. growing on ophiolitic substrates. For comparison of the subspecies, bioconcentration and translocation factors were used, as well as Spearman’s rank correlation coefficients for concentrations of elements in root and shoot samples. Chemical characteristics of the soil samples (pH, organic C, P2O5, K2O, Ca, Fe, Mg, Mn, Ni, Zn, Cu, Cr, Co, Cd and Pb) and plant samples (P2O5, K2O, Ca, Fe, Mg, Mn, Ni, Zn, Cu, Cr, Co, Cd and Pb) were determined, as well as bioconcentration and translocation factors and correlation matrices. All the three subspecies acted as strong Ni accumulators, with equal concentrations of Ni in roots and shoots, the values being several times higher than 100 mg kg–1, exceeding concentrations of available Ni in the soil. Concentrations of Cu and Cr in the aboveground plant tissues in samples from three localities were several times higher than expected, even for plants growing on metalliferous soils, exceeding, by multiple times, the available concentrations in the soil samples.

Evidence indicative of layering in the original parent material of a soil can be obtained from trace-element profiles. Some of the layers detected by this means in the parent materials of the brigalow soils examined were not apparent in the field. Trace element profiles also provided confirmatory evidence for the occurrence of a buried soil. The present alkaline-acid boundary of brigalow soils with acid substrata frequently did not coincide with a layer interface, and two distinct levels of concentration of pH-sensitive trace elements were found in the alkaline layer of some of these soils. These observations are compatible with movement of the alkaline-acid boundary during pedogenesis. Of the elements boron, cobalt, copper, gallium, manganese, molybdenum, nickel, lead, vanadium, and zirconium, all but cobalt, manganese, and nickel, which were pH-sensitive, had profiles that were typical of grey and brown soils of heavy texture. In addition, the average silt-plus-clay profile of the brigalow soils examined was almost identical with that of typical soils of this taxonomic group. These results support the conclusion from field observations that, apart from reaction, brigalow soils are mostly typical grey or brown soils of heavy texture.
