Deposition, burial and sequestration of carbon in an oligotrophic, tropical lake

Journal of Limnology, 2014
The amount of biogenic carbon that may be deposited, buried and eventually preserved (sequestered) in the sediments of a tropical, oligotrophic lake, was evaluated based on i) the temporal variation of the particulate organic carbon (POC) concentration ...

Carbon dioxide dynamics in a lake and a reservoir on a tropical island (Bali, Indonesia). [PDF]

PLoS ONE, 2018
Water-to-air carbon dioxide fluxes from tropical lakes and reservoirs (artificial lakes) may be an important but understudied component of global carbon fluxes.

Phytoplankton Biodiversity in Two Tropical, High Mountain Lakes in Central Mexico

Diversity, 2022
Lakes El Sol and La Luna, inside the crater of the Nevado de Toluca volcano, Central Mexico, are the only two perennial high mountain lakes [HML] in the country. HML are considered among the most comparable ecosystems worldwide. These lakes are “extreme”

Biogeochemical characteristics of a tropical lake [PDF]

, 2023
Biogeochemical analyses of lacustrine environments are well-established methods that allow exploring and understanding complex systems in the lake ecosystem. However, most were conducted in temperate lakes controlled by entirely different physical conditions than in tropical climates.

Nutritional assessment of tropical pastures as a sustainability strategy in dual-purpose cattle ranching in the South of Lake Maracaibo, Venezuela

Journal of the Saudi Society of Agricultural Sciences, 2021
Pastures represent the greatest sustainability challenge for tropical cattle, as they are fibrous pastures, low in protein, with few soluble carbohydrates and limited digestibility.

Tropical forests as drivers of lake carbon burial

Nature Communications, 2022
AbstractA 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 (OC) accumulation information for lakes surrounded by highly productive rainforests at warm ...

Macroinvertebrate communities associated with macrophyte habitats in a tropical man-made lake (Lake Taabo, Côte d’Ivoire)

Knowledge and Management of Aquatic Ecosystems, 2011
An ecological study was done on Lake Taabo with the main objective of characterising macroinvertebrate communities associated with the microhabitats created mainly by Eichhornia crassipes and other littoral native macrophytes.

Effects of daily changes in environmental factors on the abundance and richness of Odonata Efeitos das mudanças diárias dos fatores ambientais sobre a abundância e a riqueza de Odonata

Acta Limnologica Brasiliensia, 2011
AIM: The aim of this work was to investigate the effects of daily changes in surface water abiotic factors on the abundance of Odonata larvae and the genus richness in a lateral lake isolated from a tropical river during the nycthemeral cycle in dry and ...

Diatom assemblage in a tropical lake of northeastern Brazil [PDF]

Brazilian Archives of Biology and Technology, 2010
The composition and spatial variation of diatom assemblage in surface sediments of Caçó Lake (shallow, mesotrophic and weakly acid lake - Maranhão State, Brazil) were analyzed in order to know the distribution pattern of the species along the lake during rainy season (April 1999).

The distribution of Siombak lake sediments, a tropical tidal lake in Indonesia

IOP Conference Series: Earth and Environmental Science, 2022
Abstract Siombak Lake is one of Indonesia’s tropical tidal lakes located in Medan City, North Sumatra Province. This lake is very dynamic because the lake water level is fluctuating according to the Belawan waters’ tidal (Malacca Strait). This study aims to determine the distribution of sediments in Siombak Lake.
