In this paper, we construct and analyze a theoretical, deterministic 5 D mathematical model of Limnothrissa miodon with nutrients, phytoplankton, zooplankton, Hydrocynus vittatus predation. Local stability analysis results agree the numerical simulations in that coexistence equilibrium is locally stable provided certain ...

While it is well established that ecosystem subsidies--the addition of energy, nutrients, or materials across ecosystem boundaries--can affect consumer abundance, there is less information available on how subsidy levels may affect consumer diet, body condition, trophic position, and resource partitioning among consumer species. There is also little information on whether changes in vegetation ...

After 8 years of silence, dengue virus serotype 2 (DENV-2) reemerged in southeastern Senegal in 1999. Sixty-four DENV-2 strains were isolated in 1999 and 9 strains in 2000 from mosquitoes captured in the forest gallery and surrounding villages. Isolates were obtained from previously described vectors, Aedes furcifer, Ae. taylori, Ae. luteocephalus, and--for the first time in Senegal--from Ae. a...

Received 4 January 2005. Accepted 9 November 2005. Distributed December 2005. Abstract Circumstantial evidences for mimicry of scorpions by the neotropical gecko Coleodactylus brachystoma (Squamata, Gekkonidae) in the Cerrados of central Brazil. There are few records of invertebrates mimicry by reptiles. In the Cerrados of central Brazil, the small Coleodactylus brachystoma is an endemic specie...

Levels of biodiversity in the Neotropics are largely underestimated despite centuries of research interest in this region. This is particularly true for the Cerrado, the largest Neotropical savanna and a formally recognized biodiversity hotspot. Molecular species delimitation methods have become essential tools to uncover cryptic species and can be notably robust when coupled with morphological...
