The Santa Cruz River is the last free flowing river in Patagonia Argentina. Two dams are projected and no pre-impoundment study has been undertaken. The present research studies macroinvertebrate communities along three ...
Functional response of benthic macroinvertebrates to fire disturbance in patagonian streams
(Springer, 2021-04)
Disturbances often act as ecological filters through which only certain combinations of biological traits may pass. Here, we aimed to determine if an unprescribed human-started wildfire can act as a filter for stream-dwelling ...
Effect of environmental factors on the abundance variations of two native rodents in agricultural systems of Buenos Aires, Argentina
(Wiley Blackwell Publishing, Inc, 2019-02)
Our aim was to assess the effect of environmental factors on short temporal abundance variations of the two most abundant native rodents of agricultural agroecosystems, Akodon azarae and Calomys laucha. We conducted a ...
Complex trait‒environment relationships underlie the structure of forest plant communities
(Wiley Blackwell Publishing, Inc, 2021-08)
Traits differentially adapt plant species to particular conditions generating compositional shifts along environmental gradients. As a result, community-scale trait values show concomitant shifts, termed trait‒environment ...
Sociocultural Variables That Impact High School Students’ Perceptions of Native Fauna: a Study on the Species Component of the Biodiversity Concept
(Springer Netherlands, 2017-02)
This study investigates the influence of school sector (private versus state schools) and student gender on knowledge of native fauna. Our main objectives were (a) to describe the knowledge of high school students from the ...
Conteo de marcas de yemas para estimar la edad en Polylepis tarapacana: Una técnica potencialBud mark count to estimate age in Polylepis tarapacana: A potential technique
(Asociación Argentina de Ecología, 2021-03)
En las especies forestales que presentan un crecimiento determinado, las yemas generan marcas que se usan para estimar las edades a lo largo de brotes apicales o de ramas, mediante el conteo de entrenudos. Para estimar la ...
