Última Longitudinal habitat disruption in Neotropical streams: fish assemblages under the influence of culverts Neotropical Ichthyology Mariano,José Roberto; Makrakis,Maristela Cavicchioli; Kashiwaqui,Elaine Antoniassi Luiz; Celestino,Elaine Fernandes; Makrakis,Sergio. This study assessed differences in fish assemblages existing upstream and downstream two types of culverts, one on each of two different Neotropical streams. We analyzed the composition and structure of the ichthyofauna and tested for spatial patterns. Fish sampling was carried out monthly between November 2009 and October 2010 using different fishing gears. We collected 2,220 fish of 33 species; 901 in stretches of the Lopeí stream - circular culvert and 1,310 in stretches of the Pindorama stream - box culvert. Fish abundance was similar in upstream and downstream stretches of the circular culvert, whereas it was slightly higher in the upstream than downstream stretch for the box culvert. Characiformes predominated in the upstream stretch of both... Tipo: Info:eu-repo/semantics/article Palavras-chave: Fish passage; Fish population; Habitat fragmentation; Road crossings.
