Ants, an ecologically successful and numerically dominant group of animals, play key ecological roles as soil engineers, predators, nutrient recyclers, and regulators of plant growth and reproduction in most terrestrial ecosystems. Further, ants are widely used as bioindicators of the ecological impact of land use. We gathered information of ant species in the Atlantic Forest of South America. The ATLANTIC ANTS data set, which...

Piscirickettsiosis ( SRS ) is the most prevalent bacterial disease in Chilean salmon aquaculture and is responsible for high economic losses. The aim of this study was to comparatively characterize the pathogenesis of SRS in post‐smolt Atlantic salmon during the early and late stages of infection with Piscirickettsia salmonis LF ‐89‐ like ( PS ‐ LF ‐89) and EM ‐90‐ like ( PS ‐ EM ‐90) using a cohabitation challenge. The pathog...

Mosquitoes, especially Aedes aegypti , are becoming important models for studying invasion biology. We characterized genetic variation at 12 microsatellite loci in 79 populations of Ae. aegypti from 30 countries in six continents, and used them to infer historical and modern patterns of invasion. Our results support the two subspecies Ae. aegypti formosus and Ae. aegypti aegypti as genetically distinct units. Ae. aegypti aegyp...

Thirty A tlantic salmon, S almo salar L ., with low corporal condition relative to other fish present in the culture system, were sampled from a freshwater recirculation pisciculture located in C hile. The most characteristic signs and lesions were cachexia and presence of multiple greyish‐white granulomas within internal organs. The external and internal lesions, along with the microscopic, histologic and biochemical findings...
