Here, we use a near-complete phylogenetic tree of cichlid fish species from Lake Tanganyika (LT) to test these ideas in a lake fauna.
The tourism industry has shown significant growth, as the state's snow-capped peaks, glaciers, lush green river valleys, waterfalls, lakes, flora and fauna, wildlife sanctuaries, and pilgrimage sites attract a large number of domestic and international visitors.
Due to strong morphological affinities between Lake Tanganyika's fauna and marine organisms, early investigators proposed that the lake must have been directly connected to the ocean at some point in its history [15], [16].
Occurrences such as remnant volcanic activity, fumerole activity [ 67] or periodic gas releases and rising of toxic waters [ 68, 69] may exterminate a crater lake's fish fauna.
It has mountains, sandstone pillars, lakes, streams, caves, gorges, fauna and UNESCO-World-Heritage-Site status, but Zhangjiajie isn't your average national park.
Following several volcanic eruptions (AD 186 and 1886) that eliminated most freshwater fauna from Lake Tarawera and the surrounding lakes [ 49], forage fish for trout were introduced into lakes Rotorua and Rotoiti and from there into Lake Tarawera (around 1900; [ 53]).
Moreover, the isolated evolutionary history of Lake Tanganyika's viviparid fauna implies that for the timeframe and migration events discussed in this paper the lake served neither as a gateway nor as a dispersal route.
Surface water temperature is one of the most essential and changeable environmental factors, since it influences the growth and distribution of flora and fauna of lake ecosystem.
Meanwhile, the heat pump has no negative effect on the lake's flora and fauna.
However, fish faunas of Lake Tanganyika appear to have seeded the fauna of the lake's tributaries and outflow to a larger extent [ 60] than appears the case for mollusks [ 62, 63].
The spectacular marine-like diversity of the endemic fauna of Lake Tanganyika, the oldest of the African Great Lakes, led early researchers to suggest that the lake must have once been connected to the ocean.
