Historical processes constrain metacommunity structure by shaping different pools of invertebrate taxa within the Orinoco basin
AIM: 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. LOCATION: Meta andExpand
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. WeExpand
Emergence patterns in tropical insects: the role of water discharge frequency in an Andean Stream.
The aim of this study was to examine the relationship between the emergence patterns of various groups of aquatic insects and different hydrological discharge periods. We hypothesize thatExpand
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 ofExpand
Diatom assemblages associated with turtle carapaces in the Neotropical region
Few studies have explored the ecology and interrelationship with other organisms of the many endangered freshwater turtle species inhabiting the Neotropical Region. The focus of the current study wasExpand
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 consumptionExpand
Ecoregional characteristics drive the distribution patterns of neotropical stream diatoms.
We assessed the relative influence of ecoregional features in explaining diatom distribution in the Orinoco river basin. Ecoregions in the Colombian Orinoco can be seen as imprints of theExpand
