Detecting hydrologic distinctions among Andean lakes using clumped and triple oxygen isotopes
(Elsevier, 2023)
Oxygen isotope distributions from lacustrine carbonates provide insights into climate and hydrological change, but it is difficult to isolate the influences of catchment precipitation δ18O, water temperature, and evaporation ...
Using delta C-13 stable isotopes to quantify individual-level diet variation
(SpringerNew YorkEUA, 2007)
Factors controlling the stable isotope composition and C:N ratio of seston and periphyton in shallow lake mesocosms with contrasting nutrient loadings and temperatures
(Wiley Blackwell Publishing, Inc, 2017-09)
Carbon (C) and nitrogen (N) stable isotope composition (15N:14N, δ15N and 13C:12C, δ13C) have been widely used to elucidate changes in aquatic ecosystem dynamics created by eutrophication and climate warming, often, however, ...
Carbon Stocks and Isotopic Composition of the Organic Matter in Soils Covered by Native Vegetation and Pasture in Sorocaba, SP, Brazil
(UNIV TEHRAN, 2009)
Land cover change constitutes one of main way of alteration of soil organic matter in both quantitative and qualitative terms. The goal of this study was to compare the carbon stock and the isotopic signature of the organic ...
Carbon isotope composition as a tool for quality control of herbs, spices and medicinal plants
(2006-10-01)
Isotope screening is a simple and cheap test for determining the photosynthetic pathway used by plants. The scope of this work was to classify the photosynthetic type of Melissa officinalis L. and Cymbopogon citratus [DC.] ...

VEGETATION DYNAMICS AND LANDSCAPE EVOLUTION IN THE CONTACT BETWEEN CAMPINARANA AND CAMPINA ON SPODOSOLS - DEMINI RIVER BASIN-AM (BRAZIL)
(Uniao Geomorfologia Brasileira, 2018-07-01)
The campinas and campinaranas are Amazonian ecosystems of great value, especially in the Rio Negro Basin. The campinaranas are an forest phytophysiognomy where C-4 metabolism plants predominate. The campinas are an grassland ...
