Chemical variation of surface water and groundwater in relation to water balance in the watershed of El Pescado Creek (Central-Eastern Argentina)
(Springer, 2020-09)
The watershed of El Pescado Creek has been established as a protected landscape; however, it is currently exposed to an intense land use and coverage change process, based on the conversion of grassland areas into greenhouse ...
Methodological uncertainty in resource mixing models for generalist fishes
(Springer, 2012-08)
Carbon and nitrogen stable isotope ratios are used to assess diet composition by determining bounds for the relative contributions of different prey to a predator's diet. This approach is predicated on the assumption that ...
Metabarcoding, direct stomach observation and stable isotope analysis reveal a highly diverse diet for the invasive green crab in Atlantic Patagonia
(Springer, 2021-11)
The European green crab Carcinus maenas and its sister species C. aestuarii are highly invasive species causing damage to coastal ecosystems and contributing to severe economic losses worldwide. C. maenas was first detected ...
Inter-annual variation in the trophic niche of Magellanic penguins Spheniscus magellanicus during the pre-molt period in the Beagle Channel
(Inter-Research, 2020-11)
Inter-annual variations in the diets of seabirds are often a reflection of resource availability, with population dynamics and community structure implications. We investigated the trophic niche of Magellanic penguins ...
The diet of adult and chick rock shags (Phalacrocorax magellanicus) inferred from combined pellet and stable isotope analyses
(Springer, 2020-05)
The current information about the diet composition of the rock shag (Phalacrocorax magellanicus) in the SW Atlantic coast comes mainly from conventional pellet or stomach content analysis from a few locations situated in ...
Hydrochemical and isotopic characterization of the hydrological budget of a MAB Reserve: Mar Chiquita lagoon, province of Buenos Aires, Argentina
(Springer Verlag, 2014-10)
Mar Chiquita is a coastal lagoon located in the Argentine Buenos Aires province in South America. The aim of this study was to perform a hydrochemical and stable isotopes characterization in order to better the understanding ...
Estrategias de caza y pastoreo de camélidos entre las sociedades agropastoriles (ca. siglos IV a.C. - XVI d.C.) del oeste tinogasteño (Catamarca, Argentina) : una aproximación desde los isótopos establesCamelid hunting and herding strategies among agropastoralist societies of western Tinogasta, Catamarca, Argentina (c.400 b.C. – a.D. 1600): a stable isotope approach
(Universidad Nacional del Centro de la Provincia de Buenos Aires. Facultad de Ciencias Sociales, 2019)
Este trabajo aborda las estrategias de caza y pastoreo de camélidos llevadas a cabo por las sociedades agropastoriles que habitaron el oeste tinogasteño (Catamarca) entre los siglos IV a.C. y XVI d.C. a partir del análisis ...
Carbon (δ13C) and nitrogen (δ15N) stable isotope composition in plant and soil in Southern Patagonia’s native forests.
(Wiley, 2012-01)
Stable isotope natural abundance measurements integrate across several biogeochemical processes in ecosystem N and C dynamics. Here, we report trends in natural isotope abundance (d13C and d15N in plant and soil) along a ...
Soil-geomorphology relationships and landscape evolution in a southwestern Atlantic tidal salt marsh in Patagonia, Argentina
(Pergamon-Elsevier Science Ltd, 2018-07)
Salt marshes in Patagonia ecosystem are nowadays fully recognized by ecological, pollution and phytoremediation studies but a soil genesis and geomorphology approach is currently unknown. The aim of this study was to ...
Trophic interactions and isotopic niche of octopuses and sea stars in North Patagonia
(Springer, 2020-03)
Coexistence of species is associated with differentiation of niches and partitioning of resources, which lessen niche overlap and the intensity of competition. Here, we used stable isotope analysis to evaluate and compare ...
