23. Sources of Organic Carbon in the Food Webs of Two Florida Lakes Indicated by Stable Isotopes
Carbon cycling pathways in lacustrine systems are complex because there are often multiple sources of organic carbon available to the food webs. Among the techniques used to delineate carbon flows from organic matter to consumers, stable isotope analysis may be the most powerful one because isotope compositions of consumers reflect those of the dietary carbon assimilated and incorporated into t...
متن کاملStable Isotope Application in Animal Nutrition Science
The application of stable isotope analysis (SIA) has become a standard scientific approach in Agricultural and Ecological researches and, more in general, in several disciplines such as biology, botany, zoology, organic chemistry, climatology, and nutrition. The main objectives of this paper are (1) to provide a simple definition of stable isotopes and (2) to illustrate analytical measurement m...
متن کاملTracing Water Sources of Terrestrial Animal Populations with Stable Isotopes: Laboratory Tests with Crickets and Spiders
Fluxes of carbon, nitrogen, and water between ecosystem components and organisms have great impacts across levels of biological organization. Although much progress has been made in tracing carbon and nitrogen, difficulty remains in tracing water sources from the ecosystem to animals and among animals (the "water web"). Naturally occurring, non-radioactive isotopes of hydrogen and oxygen in wat...
متن کاملClimatic and Environmental Reconstruction Based on Stable Isotopes of Parishan Lake (Iran)
The isotopic documents of lake deposition are suitable potential means for studyingthe intercontinental, environmental and climatic conditions. In order to study theenvironmental and climatic conditions of Parishan area in Fars province in Holocene, a Corewas taken with the length of 2m from the Parishan lake sediment. From this core, kernel timeseries was provided from documents of carbon and ...
متن کاملAncient Diet Reconstruction: A Case Study of Sidon, Lebanon
The present work is associated with dietary reconstruction using δ13C and δ15N analysis of humans from the site of Sidon, a Middle Bronze Age (2000BC-1550BC) settlement in Lebanon. The main objective of this research is to focus on collagen extraction of 23 individual bones, discovered in a cemetery, College site (season 2001-2002) in ancient Sidon. Collagen could only be extracted from the 8 a...
