Title: White-tailed Kites - Stable Isotope Data

Geospatial_Data_Presentation_Form: maps data

Description:

Abstract:: These data represent tissue samples collected from White-tailed kites (Elanus leucurus), their prey, or vegetation around Kite nests. The samples are collected as part of a project investigating trophic relationships using stable isotope analysis.

Purpose:: To examine the trophic relationships within and between kite populations.

Methodology_Description:: Whole body isotopic analyses from a number of different tissues collected from white-tailed kites, its main prey species (California Vole and House Mouse), and plant species that these prey animals feed upon are done to determine the variation of isotopic deposition within the tissues of each of these organisms. Samples are analyzed for their isotopic composition of carbon, nitrogen, hydrogen, oxygen, and sulfur. Comparative analyses between trophic levels will be made to determine the level of isotopic bioaccumulation through the kite food chain.

Process_Step:

Process_Description:: Stable isotope techniques are used to investigate diet and habitat use for current and historic white-tailed kite populations in California and examine trophic relationships between populations.
