Journal of Limnology, 2014 The deep benthic communities of tropical lakes are poorly understood with respect to their composition, abundance, biomass and regulatory factors. Whereas the hypolimnia of temperate oligotrophic lakes remain oxygenated, the higher temperatures in ...

Stable Isotopes Approach to Infer the Feeding Habit and Trophic Position of Freshwater Fishes in Tropical Lakes [PDF]
Iranica Journal of Energy and Environment, 2016 A study was conducted on the stable isotope variation of muscle tissues from selected freshwater fish species from Temenggor Lake and Chenderoh Lake, Perak, Malaysia from December 2014 to March 2015. The objective is to assess the stable isotopes of δ13C

Tropical Lakes May Emit More Methane
Eos, 2021 Fresh waters are one of the primary sources of natural methane emissions, but methane dynamics in tropical lakes are not as well understood as those in more temperate regions.

Short-term variability in the sedimentary BIT index of Lake Challa, East Africa over the past 2200 years : validating the precipitation proxy [PDF]
, 2015 . The branched vs. isoprenoid index of tetraethers (BIT index) in Lake Challa sediments has been applied as a monsoon precipitation proxy on the assumption that the primary source of branched tetraether lipids (brGDGTs) was soil washed in from the lake's

Knowledge and Management of Aquatic Ecosystems, 2023 Tropical freshwater wetlands are subject to multiple stressors but there is little information on which stressors cause wetland degradation. Increased turbidity is considered a major cause of degradation, but the effects of introduced fish are often ...

The significance of the pycnocline in tropical lakes [PDF]
, 1972 The vertical temperature profile is a poor indicator of sratification in most tropical lake. Data from Lake Bunyonyi, Uganda, showed, however, that the density profile highlighted discontinuity layers whieh were not obvious from the temperature profile ...

Understanding the performance of the FLake model over two African Great Lakes [PDF]
Geoscientific Model Development, 2014 The ability of the one-dimensional lake model FLake to represent the mixolimnion temperatures for tropical conditions was tested for three locations in East Africa: Lake Kivu and Lake Tanganyika's northern and southern basins. Meteorological observations

Assessing seasonal nitrogen export to large tropical lakes
Science of The Total Environment, 2020 Rivers are exporting increasing amounts of nitrogen (N) to lakes, which is leading to eutrophication. However, the seasonality apparent in nutrient loading, especially in tropical areas, is thus far only partially understood. This study aims to better understand the seasonality and the sources of dissolved inorganic nitrogen (DIN) inputs from sub ...
