Altitudinal patterns in two syntopic species of sturnira (Mammalia: Chiroptera: Phyllostomidae) in the Montane rain forests of Argentina
(Wiley, 2014-01)
We evaluated altitudinal segregation in two Sturnira species as a mechanism allowing their coexistence. Tests were devised to discern between interspecific interactions and regional responses to geographic and environmental ...
Contrasting patterns of taxonomic, phylogenetic and functional variation along a Costa Rican altitudinal gradient in the plant family Melastomataceae
(Cambridge University Press, 2018)
The functional composition of plant communities in montane regions has been studied for decades, and most
recent analyses find that environmentally favourable landscapes at lower altitudes tend to be dominated by species ...
Mountain invasions on the way: are there climatic constraints for the expansion of alien woody species along an elevation gradient in Argentina?
(Oxford University Press, 2015-10)
Aims Increasing evidence worldwide indicates that high mountain regions are not immune to invasion by alien plants. Here we aimed to address whether three major woody invaders of low-mountain areas are constrained to lower ...
Altitudinal patterns of wind transport and deposition of Yungas tree pollen in northwestern Argentina: Implications for interpreting the Quaternary fossil record
(Elsevier Science, 2019-04)
The presence of pollen from Yungas tree species in fossil sequences located above the tree-line has led to alternative interpretations of past climate changes in tropical and subtropical Andes. We studied atmospheric and ...
Composition and structure of fish assemblage from Passa Cinco stream, Corumbataí river sub-basin, SP, Brazil
(Instituto Internacional de Ecologia, 2012-02-01)
O objetivo desse trabalho foi determinar a composição da assembleia de peixes do Rio Passa Cinco, além de verificar alterações em sua estrutura em função do gradiente altitudinal. Foram realizadas seis amostragens em cinco ...

Fragmentation and altitudinal effects on tree diversity in seasonally dry forests of Mexico and Chile
(Newton, A.Tejedor, N. (Eds.)UICN, Cambridge, 2011)
Changes in the number of plant or animal species in relation to area of habitat patch (Harris, 1984), latitude and, its mirror image elevation (Rahbek, 1997), provide the best-known relation-ships describing natural patterns ...
Drivers of diversity and altitudinal distribution of chironomids (Diptera: Chironomidae) in the Ecuadorian Andes
(Universidad de Costa Rica, 2021)
