A Snail's Pace in a Snail’s Space: Adult movement rates of Lavigeria gastropods in Lake Tanganyika, East Africa
ثبت نشده
چکیده
Little quantitative data about the movement rates of freshwater gastropods is available. Knowledge of these rates can lead to a better understanding of gastropods and their interactions with the environment. Rate of movement at an individual level has several implications for survival and reproduction. In patchy freshwater systems, movement rates are a limiting factor in the gastropod's ongoing search for suitable habitats. These habitats must have an ample food supply, low competition (from conspecifics and other species), sufficient protection from predators, and easy access to mates. In the adult stages of life, active movement is a precursor to dispersal. A firm grasp on the potential for movement at a species level will dictate how large a role dispersal plays in population structure and distribution.

Snail 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 کاملDo gastropod abundances and distributions vary in relation to primary productivity and site complexity? Student: Brittany Huntington Mentor:
Population ecology incorporates a variety of foundational tenets that aid in understanding community structure and biodiversity of organisms in the natural world. For example, it has been observed that increasing the habitat and environmental complexity is correlated with increasing species diversity (Rosenzweig, 1995). Lake Tanganyika, in central East Africa, represents an ideal system to test...

For example among the gastropods 80% of the species found in the lake are endemic. Most diversity is displayed in the family Thiaridae. The genus Lavigeria it is the most common thiarid genus and at the same time the most diverse (Michel 1995). It has an estimated species diversity of 20 or more endemic species (Michel & Todd, in prep). The often sympatric species show many shell morphological ...
متن کاملAncient lakes as evolutionary reservoirs: evidence from the thalassoid gastropods of Lake Tanganyika.
Ancient lakes are often collectively viewed as evolutionary hot spots of diversification. East Africa's Lake Tanganyika has long been the subject of scientific interest owing to dramatic levels of endemism in species as diverse as cichlid fishes, paludomid gastropods, decapod and ostracod crustaceans and poriferans. It is the largest and deepest of the African rift lakes, and its endemic fauna ...
متن کاملLake-level history of Lake Tanganyika, East Africa, for the past 2500 years based on ostracode-inferred water-depth reconstruction
Assemblages of ostracodes from sediment cores illuminate lake-level history at decadal to centennial timescales during the late Holocene at Lake Tanganyika, East Africa. The ostracode-based lake-level curves for several cores resemble both each other and the only previously published lake-level record of comparable resolution for Lake Tanganyika during this interval, successfully reconstructing...
