Abstract Sympatric speciation is a contentious concept, although theoretical models as well as empirical evidence support its relevance in evolutionary biology. The Midas cichlid species complex (Amphilophus citrinellus, labiatus, zaliosus) from several crater lakes in Nicaragua fits several of the key characteristics of a sympatric speciation model. In particular, in A. citrinellus (i) strong ...

Lakes Nicaragua and Managua are large, rather shallow, fresh-water bodies that lie in a late Tertiary and Quaternary graben in western Nicaragua. The bottom sediments comprise highly organic diatomaceous volcanic silts and clays in which quartz plagioclase feldspar, dioctahedral montmorillonite and volcanic glass are the principal constituents. ' Organic nitrogen content of the lake sediments r...

® A hamster model was used to determine the protector capacity of vax-SPIRAL against the lethal infection after challenge with 10,000 LD of four strains isolated of a leptospirosis outbreaks in Nicaragua. These strains were 50 selected from a primary group of 16 belonging to the serogroups strains Ballum, Icterohemorragiae, Pomona, Serjoe and Pyrogenes. Most of these, except Pyrogenes serogroup...

This paper presents an evaluation of IT service delivery by Internet Service Providers (ISPs) from Nicaragua at the end of 2009.

The Nicaraguan government showed scant evidence of having accounted for the impact on the environment and on local residents, or of having adequately consulted the public in selecting the final 278-km route. Such disregard should be alarming to everyone. Proj...
