Spatial variation in the strength of mutualism between a jumping spider and a terrestrial bromeliad: Evidence from the stable isotope N-15
(Gauthier-villars/editions Elsevier, 2008-05-01)
Psecas chapoda, a neotropical jumping spider strictly associated with the terrestrial bromeliad Bromelia balansae in cerrados and semi-deciduous forests in South America, effectively contributes to plant nutrition and ...
Can stable isotopes ride out the storms? The role of convection for water isotope in models, records, and paleoaltimetry studies in the central Andes
(Elsevier, 2014-10-24)
Abstract: Globally, changes in stable isotope ratios of oxygen and hydrogen (δ18Oand δD) in the meteoric water cycle result from distillation and evaporation processes. Isotope fractionation occurs when air masses rise in ...
Stable isotopes document mainland-island divergence in resource use without concomitant physiological changes in the lizard Liolaemus pictus
(2010)
Shifts in feeding ecology are believed to promote island-mainland divergence. The lizard Liolaemus pictus has several different subspecies on Chilean islands and mainland. These subspecies inhabit contrastingly different ...

Diet and trophic position of the devil rays Mobula thurstoni and Mobula japanica as inferred from stable isotope analysis
(Journal of the Marine Biological Association of the United Kingdom, 2010)
This study confirms the diet and determines the trophic position of the bentfin devil ray (Mobula thurstoni) and spinetail devil ray (Mobula japanica) in the south-west Gulf of California. There has been an active fishery ...
Moisture origin and stable isotope characteristics of precipitation in southeast Siberia
(John Wiley and Sons Ltd, 2020)
The paper presents oxygen and hydrogen isotopes of 284 precipitation event samples systematically collected in Irkutsk, in the Baikal region (southeast Siberia), between June 2011 and April 2017. This is the first ...
Stable isotopes (H-2, O-18 and C-13) in groundwaters from the northwestern portion of the Guarani Aquifer System (Brazil)
(Springer, 2010-09-01)
The groundwater flow pattern of the western part of the Guarani Aquifer System (GAS), Brazil, is characterized by three regional recharge areas in the north, and a potentiometric divide in the south, which trends north-south ...
Living on the coast without depending on coastal resources. Isotopic evidence in Central Chile
(Elsevier Ltd, 2019)
Along the Pacific coast of South America, including what is now Chilean territory, the coastal zone has been exploited since the earliest peopling of the continent and marine resources played an important role in the ...
