Tropical forests as drivers of lake carbon burial

open access: yesNature Communications, 2022
A significant proportion of carbon (C) captured by terrestrial primary production is buried in lacustrine ecosystems, which have been substantially affected by anthropogenic activities globally. However, there is a scarcity of sedimentary organic carbon (

Morphometry and mixing regime of a tropical lake: Lake Nova (Southeastern Brazil) [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2016
Lake Nova (15.5 km2) is the second largest lake in the Lower Doce River Valley (Southeastern Brazil). A better understanding of ecosystem structure and functioning requires knowledge about lake morphometry, given that lake basin form influences water ...

Analysis on the distribution of zooplankton in tropical shallow urban lakes [PDF]

open access: yesE3S Web of Conferences, 2021
The distribution characteristics of zooplankton in shallow urban lakes of Lingnan that in the tropics and subtropics were studied. The results showed that Brachionus, Trichocerea, and Lecane were dominant species of composition and abundance.

Sediment Infill of Tropical Floodplain Lakes: Rates, Controls, and Implications for Ecosystem Services

open access: yesFrontiers in Earth Science, 2022
Shallow lakes in tropical floodplains provide significant ecosystem services that can be altered by natural and anthropogenic forces. Despite their importance, little is known about the infill patterns and timescales and the magnitude of these changes in

Temporal variation of rotifer community in three climatic zones and their relationship with environmental factors

open access: yesJournal of Freshwater Ecology, 2021
Comparative analyses of rotifer community structure in freshwater lakes among different climatic zones are limited. In this study, six freshwater lakes located in warm temperate, subtropical and tropical zones were selected to investigate the annual ...

Nitrogen is unlikely to consistently limit primary productivity in most tropical lakes

open access: yesEcosphere, 2023
Despite mounting evidence that tropical lakes may experience an array of phytoplankton nutrient limitation regimes, references to low‐latitude lakes being predominantly nitrogen limited remain common in the literature. To assess the current understanding

Small changes in climate can profoundly alter the dynamics and ecosystem services of tropical crater lakes. [PDF]

open access: yesPLoS ONE, 2014
African tropical lakes provide vital ecosystem services including food and water to some of the fastest growing human populations, yet they are among the most understudied ecosystems in the world. The consequences of climate change and other stressors on

Benthic macroinvertebrates of a tropical lake: Lake Caçó, MA, Brazil [PDF]

open access: yesBrazilian Journal of Biology, 2010
Benthic communities are highly relevant in the study of aquatic ecosystems, both for their role in the functioning of the ecosystem and also as markers or indicators of paleo-conditions. Their distribution, as in other communities, is conditioned by abiotic and biotic factors and to their interactions, which determine the structure of the community ...

Turnover Drives High Benthic Macroinvertebrates’ Beta Diversity in a Tropical Karstic Lake District

open access: yesDiversity, 2022
Beta diversity is useful to explain community assembly across landscapes with spatial variation. Its turnover and nestedness components help explain how beta diversity is structured across environmental and spatial gradients.

Under vaccination of children among Maasai nomadic pastoralists in Kenya: is the issue geographic mobility, social demographics or missed opportunities?

open access: yesBMC Public Health, 2018
Background Nomadic lifestyle has been shown to be a significant factor in low immunization coverage. However, other factors which might aggravate vaccination uptake in nomadic pastoralists are poorly understood.
