Historical processes constrain metacommunity structure by shaping different pools of invertebrate taxa within the Orinoco basin
To identify and characterize the distribution of invertebrate taxa in the Orinoco basin and how their distribution affects the metacommunity structure along the river network.
Upstream refugia and dispersal ability may override benthic-community responses to high-Andean streams deforestation
Deforestation is a major driver of biodiversity loss in the Tropical region, but the role of upstream refugia and dispersal ability on the community response to this disturbance is unknown. We
Ecoregional characteristics drive the distribution patterns of neotropical stream diatoms.
Evidence is provided showing that both historical legacies and contemporary environmental conditions are interacting to determine diatoms' distribution, suggesting the need to consider ecoregional gradients for unraveling the mechanisms shaping tropical diversity as well as for designing conservation plans.
Dynamics of photosynthetic pigments in an Andean lake in Colombia
Guatavita Lake is a small, sheltered tropical high mountain lake located in the Colombian Andes, with a closed watershed and a maximum depth of 25 m. It is the freshwater source for human consumption
Emergence patterns in tropical insects: the role of water discharge frequency in an Andean Stream.
It is shown that the response of macroinvertebrates to discharge can be differentiated and can produce relevant changes in biodiversity.
Changes in invertebrate assemblage structure as affected by the flow regulation of a páramo river
Flow regulation can alter the structure and dynamics of lotic communities, especially in rivers with unpredictable high-flow events, such as those flowing through the Paramo, an endemic ecosystem of
Diatom assemblages associated with turtle carapaces in the Neotropical region
Characterizing their epibiont diatom assemblages may contribute to the authors' understanding of diatom distribution on larger scales, as well as give some clues as to the auto-ecology of turtles that help to effectively determine conservation areas for these endangered species.
