Phylogenetic Relationships of Gomphocythere (ostracoda) in Lake Tanganyika, East Africa
We examined the distribution of 44 morphological characters for 16 extant species of an ostracode genus, Gomphocythere, in Africa, to test hypotheses concerning character development and speciation patterns. Using heuristic searches conducted with the phylogenetic reconstruction program PAUP (beta version, 4.0), we found 2 trees of 98 steps (CI = 0.56). The skewness of tree length distribution ...
متن کاملSnail susceptibility to crab predation: A case study of co-evolution from Lake Tanganyika, East Africa
Co-evolution has been invoked as an explanation for Lake Tanganyika’s unusual endemic fauna. The crabs Platytelphusa armata and Potamonautes platynotus are molluscivores, found in the same habitats as the gastropods Lavigeria coronata, L. grandis, and L. nassa (West & Cohen 1994). As these are the largest gastropods in the Lavigeria species flock, and often the most exposed, we are determining ...
متن کاملLepidiolamprologus kamambae, a new species of cichlid fish (Teleostei: Cichlidae) from Lake Tanganyika
Lepidiolamprologus kamambae is described from the Kamamba Island off the southeastern coast of Lake Tanganyika. It is similar to L. elongatus, L. kendalli, and L. mimicus in the presence of three horizontal rows of dark blotches along the sides. It differs from those species in the presence of a distinct suborbital stripe across the cheek. It is further distinguished from L. elongatus and L. mi...
متن کاملAn examination of factors controlling biogenic silica preservation in modern sediments from east-central Lake Tanganyika, East Africa
The biogenic silica (BSi) content of sediments has been used to infer past primary productivity in marine and lacustrine systems (Johnson et al., 2002; Verschuren et al., 2002). Biogenic silica is derived from the fossil remains of diatoms, sponge spicules, and plant phytoliths; however, diatoms make up the overwhelming source of BSi in most aquatic systems. Diatoms are important primary produc...
متن کاملEffects of land-use change on aquatic biodiversity: A view from the paleorecord at Lake Tanganyika, East Africa
Population growth and watershed deforestation in northwestern Tanzania threaten the biodiversity of Lake Tanganyika through erosion and habitat degradation. We used cores collected offshore from Gombe Stream National Park and a deforested watershed to reconstruct how land-use changes in the Gombe Stream area since A.D. 1750 have affected lake biodiversity. Paleoenvironmental and paleoecological...
