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

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 ...

The Dynamic of Phytoplankton Community Structure in Face of Warming Climate in A Tropical Man-Made Lake

Biosaintifika: Journal of Biology & Biology Education, 2017
In freshwater ecosystems, water temperature plays as an environmental factor that regulates its structure and function. A research on the impacts of changes in temperature to the dynamics of the Phytoplankton community structure has been done.
