In search of a bacterial spedes definition
(Universidad de Costa Rica., 1997)The bacterial species concept was examined within the framework of plant and animal associated a-2 proteobacteria, taking into consideration the phylogenetic, taxonomic and biological approaches as well as the microbiologists' ... -
Hot temperatures can force delayed mosquito outbreaks via sequential changes in Aedes aegypti demographic parameters in autocorrelated environments
(Elsevier B.V, 2014)Aedes aegypti L. (Diptera: Culicidae) is a common pantropical urban mosquito, vector of dengue, Yellow Fever and chikungunya viruses. Studies have shown Ae. aegypti abundance to be associated with envi ronmental fluctuations, ... -
