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 ...

Plant water resource partitioning and isotopic fractionation during transpiration in a seasonally dry tropical climate [PDF]
, 2017 Lake Chala (3 degrees 19' S, 37 degrees 42' E) is a steep-sided crater lake situated in equatorial East Africa, a tropical semiarid area with a bimodal rainfall pattern. Plants in this region are exposed to a prolonged dry season, and we investigated if (

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”

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.

Large CO2 disequilibria in tropical lakes [PDF]
Global Biogeochemical Cycles, 2009 On the basis of a broad compilation of data on pCO2 in surface waters, we show tropical lakes to be, on average, far more supersaturated and variable in CO2 (geometric mean ± SE pCO2 = 1804 ± 35 μatm) than temperate lakes (1070 ± 6 μatm). There was a significant negative relationship between pCO2 and latitude, resulting in an average decrease of pCO2 ...

Sensitivity of the grassland-forest ecotone in East African open woodland savannah to historical rainfall variation [PDF]
, 2014 . Fossil pollen records provide key insight into the sensitivity of terrestrial ecosystems to climate change at longer time scales. However, tracing vegetation response to relatively modest historical climate fluctuations is often complicated by the ...

Initiation of a Stable Convective Hydroclimatic Regime in Central America Circa 9000 Years BP [PDF]
, 2020 Many Holocene hydroclimate records show rainfall changes that vary with local orbital insolation. However, some tropical regions display rainfall evolution that differs from gradual precessional pacing, suggesting that direct rainfall forcing effects ...

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.

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 ...

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.
