ICDP workshop on the Lake Tanganyika Scientific Drilling Project: a late Miocene–present record of climate, rifting, and ecosystem evolution from the world's oldest tropical lake [PDF]

open access: yesScientific Drilling, 2020
The Neogene and Quaternary are characterized by enormous changes in global climate and environments, including global cooling and the establishment of northern high-latitude glaciers.

Century-to-millennial scale climatic variability in Lake Malawi revealed by isotope records [PDF]

open access: yes, 2007
Diatom-based oxygen isotope data (δ18Odiatom) from Lake Malawi show multi-centennial scale wet–dry intervals spaced approximately every 2.3 ka throughout a 25 ka sequence.

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

open access: yesJournal 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 ...

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

open access: yesDiversity, 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]

open access: yesPLoS 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.

Water temperature and some water quality in Lake Toba, a tropical volcanic lake

open access: yes, 2023
In 2014, 2018 and 2021, we measured the vertical distributions of several water quality indicators in Lake Toba, a representative large tropical lake. This lake has a north basin (NB) and south basin (SB), connected by a strait. Similar water temperature

Growth, biomass, and production of two small barbs (Barbus humilis and B. tanapelagius, Cyprinidae) and their role in the food web of Lake Tana (Ethiopia) [PDF]

open access: yes, 2009
Growth, biomass and production of two small barbs (Barbus humilis and Barbus tanapelagius) and their role in the food web of Lake Tana were investigated.

Biogeochemical characteristics of a tropical lake [PDF]

open access: yes, 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.

Bacterial GDGTs in Holocene sediments and catchment soils of a high Alpine lake: application of the MBT/CBT-paleothermometer [PDF]

open access: yes, 2011
A novel proxy for continental mean annual air temperature (MAAT) and soil pH, the MBT/CBT-paleothermometer, is based on the temperature (T) and pH-dependent distribution of specific bacterial membrane lipids (branched glycerol dialkyl glycerol ...
