Lake Retba
Lake Retba, also known as Lac Rose (meaning " pink lake"), lies north of the Cap Vert peninsula in Senegal, some north-east of the capital, Dakar, in northwest Africa. It is named for its pink waters caused by ''Dunaliella salina'' algae and is known for its high salt content, up to 40% in some areas. Its colour is usually particularly strong from late January to early March, during the dry season. Flooding in September 2022 not only disrupted salt harvesting activities on the lake, but also led the lake to lose its colour, causing a negative effect on tourism. However, as of 2025, the lake has regained some of its colour. The lake is under consideration by UNESCO as a World Heritage Site. Description The lake is situated north-east of Dakar, separated from the Atlantic Ocean only by a narrow corridor of dunes, and is named for its pink waters, which are caused by ''Dunaliella salina'' algae. The algae produce a red pigment to help them absorb sunlight, which gives them ene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dry Season
The dry season is a yearly period of low rainfall, especially in the tropics. The weather in the tropics is dominated by the tropical rain belt, which moves from the northern to the southern tropics and back over the course of the year. The temperate counterpart to the tropical dry season is summer or winter. Rain belt The tropical rain belt lies in the southern hemisphere roughly from November to March; during that time the northern tropics have a dry season with sparser precipitation, and days are typically sunny throughout. From May to September, the rain belt lies in the northern hemisphere, and the southern tropics have their dry season. Under the Köppen climate classification, for tropical climates, a dry season month is defined as a month when average precipitation is below . The rain belt reaches roughly as far north as the Tropic of Cancer and as far south as the Tropic of Capricorn. Near these latitudes, there is one wet season and one dry season annually. At the ...

Blackchin Tilapia
The blackchin tilapia (''Sarotherodon melanotheron''), formerly ''Tilapia melanotheron, T. heudelotii'' and ''T. leonensis'', is a species of cichlid native to coastal west Africa.

Salinity
Salinity () is the saltiness or amount of salt (chemistry), salt dissolved in a body of water, called saline water (see also soil salinity). It is usually measured in g/L or g/kg (grams of salt per liter/kilogram of water; the latter is dimensionless and equal to per mille, ‰). Salinity is an important factor in determining many aspects of the chemistry of natural waters and of biological processes within it, and is a state function, thermodynamic state variable that, along with temperature and pressure, governs physical characteristics like the density and heat capacity of the water. A contour line of constant salinity is called an ''isohaline'', or sometimes ''isohale''. Definitions Salinity in rivers, lakes, and the ocean is conceptually simple, but technically challenging to define and measure precisely. Conceptually the salinity is the quantity of dissolved salt content of the water. Salts are compounds like sodium chloride, magnesium sulfate, potassium nitrate, and sod ...

Microbiome
A microbiome () is the community of microorganisms that can usually be found living together in any given habitat. It was defined more precisely in 1988 by Whipps ''et al.'' as "a characteristic microbial community occupying a reasonably well-defined habitat which has distinct physio-chemical properties. The term thus not only refers to the microorganisms involved but also encompasses their theatre of activity". In 2020, an international panel of experts published the outcome of their discussions on the definition of the microbiome. They proposed a definition of the microbiome based on a revival of the "compact, clear, and comprehensive description of the term" as originally provided by Whipps ''et al.'', but supplemented with two explanatory paragraphs, the #First explanatory paragraph, first pronouncing the dynamic character of the microbiome, and the #Second explanatory paragraph, second clearly separating the term ''microbiota'' from the term ''microbiome''.
