Macroinvertebrates of Eichhornia crassipes (Pontederiaceae) roots in the alluvial floodplain of large tropical rivers (Argentina)

Abstract: Introduction: Eichhornia crassipes is a dominant aquatic plant of neotropical-river floodplains and is invasive in warm waters of different continents. Plants provide food and habitat for fish, especially Prochilodus lineatus and Gymnotus omarorum, which are relevant to subsistence fishing by local indigenous communities. Objective: In this study we describe the main traits of E. crassipes floating meadows, and analyze the abundance and composition of macroinvertebrate assemblages associated with their roots i… Show more

“…This area of the river has been modified to be a small reservoir and the flow is controlled by a gate adjacent to the union with the Lerma River. The higher BMWP value at this site, in contrast to the other indices, could be related to continuous flow (the gates were open in all seasons) and the presence of water hyacinths that contribute to overall biotic diversity because they offer different habitats for macroinvertebrates [60].…”

“…During rising water, floating macrophytes are retained in the oxbow lakes by the riparian forest located in the sand bars and the roots act as filters for inorganic sediments supplied by the river (Poi de Neiff et al, 1994). In this section of the Paraná floodplain, the resetting processes mentioned for other rivers (Junk et al, 1989) where floating aquatic and semi-aquatic macrophytes are exported and provide organic matter and nutrients to the main channel communities, do not occur.…”

“…Por ejemplo, la diversidad de algunas familias de lepidópteros relacionados a macrófitas acuáticas es pobre, ya que muchos taxones no están determinados a nivel genérico (Poi de Neiff, 2003;Poi de Neiff y Neiff, 2006;Poi et al, 2020). La mayoría de los estudios sobre taxonomía, biología básica y la historia de vida se llevan a cabo principalmente con especies de importancia agrícola, o para el control biológico de malas hierbas acuáticas (Center et al, 1999;Julien et al, 2001).…”

“…En general, el orden no es considerado como un componente de la comunidad acuática y ha sido constantemente excluido de los estudios sobre la ecología de los insectos relacionados con este ambiente, especialmente con las macrófitas a las cuales se relacionan la mayoría de las especies semiacuáticas (Lavery y Costa, 1972;Poi de Neiff, 2003;Poi de Neiff y Neiff, 2006;Graça y Solís, 2018;Poi, Neiff, Casco y Gallardo, 2020). Recientemente el interés por las especies semiacuáticas se ha incrementado, especialmente por la propuesta de usar algunos de sus miembros como agentes de control biológico de plantas acuáticas invasivas debido a los hábitos herbívoros de las larvas, las cuales pueden ser perforadoras, minadoras o defoliadoras…”
