- Tamaño corporal, tolerancia ecológica y potencial de bioindicación de la calidad del agua de Anacroneuria spp. (Plecoptera: Perlidae) en América del Sur Sylvie Tomanova Pablo A. Tedesco Biología egg size body size Plecoptera Anacroneuria altitudinal range Body size, ecological tolerance and potential for water quality bioindication in the genusAnacroneuria (Plecoptera: Perlidae) from South America. Knowledge about the biology and ecology ofneotropical aquatic taxa is crucial to establish general ecological rules and water protection systems. Basedmainly on published data, the present work shows the following biological and ecological characteristicsof Anacroneuria species (Klapálek 1909): a) the wide range of environmental conditions of rivers whereAnacroneuria species occur, b) species number decreases along an increasing elevation gradient, c) body sizeincreases in relation to the maximum altitude of occurrence, d) altitudinal range increases with body size, e)there is a constant relationship between male and female body size, and finally, f) larger females lay larger eggs.In temperate countries, the family Perlidae in general, and the genus Anacroneuria in particular, are viewed asexcellent water quality indicators. We suggest that, considering the complexity of the groups ecology in SouthAmerica, it should not be automatically considered an excellent bioindicator in the Neotropical region. Rev.Biol.
