Tropheus Evolution In Tanganyika Lake
African lakes have produced striking variation in cichlid fish fauna. Lake Tanganyika, whose age is estimated at 9 to 12,000,000 years, is the oldest East African lake and hides morphologically, genetically and behaviorally diverse group cichlid fish. Many of the more than 200 described species is divided into geographically and genetically distinct populations that differ primarily in their co...
متن کاملNutrient dynamics of Lake Tanganyika
The large and productive fishery of Lake Tanganyika is an important source of income and nutrition for the surrounding areas. This fishery, based primarily on pelagic clupeids (Kiswahili: dagaa), is very productive, and provides a readily available, nutritious, and inexpensive source of protein to the rapidly growing human populations in this area. The regional importance of the Lake Tanganyika...
متن کاملUpwellings recorded in Lake Tanganyika mussels
Biogenic productivity of Lake Tanganyika is highly dependent on seasonal upwellings of anoxic deep waters. We investigated the shell of freshwater bivalve Pleiodon spekii as a geochemical archive of these periodic hydrological changes tuned by the monsoon regime. The results of a 2-years-long geochemical survey of the coastal waters 5 performed on the dissolved and particulate fractions were pu...
متن کاملEcological consequences of a century of warming in Lake Tanganyika.
Deep tropical lakes are excellent climate monitors because annual mixing is shallow and flushing rates are low, allowing heat to accumulate during climatic warming. We describe effects of warming on Lake Tanganyika: A sharpened density gradient has slowed vertical mixing and reduced primary production. Increased warming rates during the coming century may continue to slow mixing and further red...
متن کاملA tribal level phylogeny of Lake Tanganyika cichlid fishes based on a genomic multi-marker approach
The species-flocks of cichlid fishes in the East African Great Lakes Victoria, Malawi and Tanganyika constitute the most diverse extant adaptive radiations in vertebrates. Lake Tanganyika, the oldest of the lakes, harbors the morphologically and genetically most diverse assemblage of cichlids and contains the highest number of endemic cichlid genera of all African lakes. Based on morphological ...
