Food web differences between two neighboring tropical high mountain lakes and the influence of introducing a new top predator.

open access: yesPLoS ONE, 2023
High mountain lakes (HMLs) are considered unique and comparable ecosystems for monitoring global climate change. The food web structure can indicate the response of these ecosystems to ecological threats, such as fish introduction, by analyzing the ...

Evapotranspiration Profiles and Trends in Seasonally Dry and Seasonally Humid Tropical Forests

open access: yesInternational Journal of Climatology, EarlyView.
Moisture availability and vegetation are decisive factors in ET variations, which are greater in the Atlantic Forest. Precipitation contributes positively to ET variations (r = 0.20–0.67). Significant trends (p < 0.05) in ET were identified, with opposing patterns.

Correlates of Zooplankton Beta Diversity in Tropical Lake Systems

open access: yesPLoS ONE, 2014
The changes in species composition between habitat patches (beta diversity) are likely related to a number of factors, including environmental heterogeneity, connectivity, disturbance and productivity. Here, we used data from aquatic environments in five Brazilian regions over two years and two seasons (rainy and dry seasons or high and low water level
