Application of isoscapes to determine geographic origin of terrestrial wildlife for conservation and management

摘要: Abstract Accounting for migration and connectivity of mobile species across the annual cycle can present challenges conservation management efforts. The use stable isotope approaches to examine movements ecology wildlife has been widespread over past two decades. Hydrogen (δ2H) composition, in particular, frequently used provide insight into origin migratory species, although isotopes other elements are sometimes used. These intrinsic markers yield valuable information about distributions on a broad scale, with reduced labor expense compared tracking telemetry. Many applications date have addressed origin, studies support biology less common. In addition, there few guides how best employ these methods management. Therefore, we an overview community may be applied problems primer process assigning geographic origins terrestrial wildlife. We also discuss practices employing environmental isoscapes (isotopic landscapes), rescaling functions, assumptions required assignment while highlighting emerging issues modeling process. Finally, example illustrate principles, explore strengths limitations this approach context.
