Última Spatio-temporal segregation and size distribution of fish assemblages as related to non-native species occurrence in the middle rio Doce Valley, MG, Brazil Neotropical Ichthyology Giacomini,Henrique Corrêa; Lima Jr.,Dilermando Pereira; Latini,Anderson Oliveira; Espírito-Santo,Helder Mateus Viana. The lakes in the middle rio Doce Valley (MG) are suffering impacts due to the introduction of invasive fish species, mainly piscivorous species like red piranha Pygocentrus nattereri and peacock bass Cichla kelberi. Fishes were collected in bimonthly samples conducted at ten lakes along a year. The present study showed that the composition of native fish assemblages is significantly related to the presence and type of non-native species. Fish species distribution among lakes can be explained by differences in species body size: smaller native species are less concentrated in lakes with invasive piscivores, which is in accordance with the hypothesis that they have greater susceptibility to predation by invaders. Another probable cause for this correlation... Tipo: Info:eu-repo/semantics/article Palavras-chave: Species invasions; Beta diversity; Metacommunity; Body size; Predation.
