Stable isotope analysis (SIA) has proven to be a useful tool in reconstructing diets,
characterizing trophic relationships, elucidating patterns of resource allocation, and …

To understand the ecology of migratory animals it is important to link geographic regions
used by individuals including breeding, wintering, and intermediate stopover sites. Previous …

Major migration events in Holocene Eurasia have been characterized genetically at broad
regional scales,,–. However, insights into the population dynamics in the contact zones are …

Niche partitioning facilitates species coexistence in a world of limited resources, thereby
enriching biodiversity. For decades, biologists have sought to understand how diverse …

A broad compilation of modern carbon isotope compositions in all C3 plant types shows a
monotonic increase in δ 13C with decreasing mean annual precipitation (MAP) that differs …

Criteria are presented for the identification of diagenetic alteration of carbon and nitrogen
isotope ratios of bone and tooth collagen prepared by a widely used method. Measurements …

Measurements of δ 15 N of consumers are usually higher than those of their diet. This
general pattern is widely used to make inferences about trophic relationships in ecological …

The “trophic level enrichment” between diet and body results in an overall increase in
nitrogen isotopic values as the food chain is ascended. Quantifying the diet–body Δ15N …

Differential fractionation of stable isotopes of carbon during photosynthesis causes C4
plants and C3 plants to have distinct carbon-isotope signatures. In addition, marine C3 …

Prey‐predator collagen enrichment values for carbon and nitrogen isotopic compositions
are investigated. New enrichment values are given for the well‐monitored ecosystem of …
