TITLE:

Community Structure of Macroinvertebrates Associated with Aquatic Macrophytes in a Neotropical Floodplain

KEY WORDS:

Metacommunities, Araguaia River, Aquatic Invertebrates, Lakes.

PAGES: 23
BIG AREA: Outra
AREA: Multidisciplinar
SUMMARY:

Macroinvertebrates are a group of organisms with high taxonomic richness and great variety in dispersal modes, which perform crucial functions in aquatic ecosystems. The structure of macroinvertebrate communities can be related to different physical, chemical, biological, and spatial processes at local and regional scales. We applied the metacommunity theory to understand the predictive relationship of these processes on the structure of this biological group. We aimed to evaluate the effects of local, spatial, and landscape predictors on the structure of the macroinvertebrate metacommunity associated with macrophyte roots in the middle Araguaia River floodplain. We hypothesized that (i) local predictors will be the main structurers of this metacommunity, and (ii) organisms with active dispersal abilities will exhibit stronger responses to local predictors than passive dispersers, due to their ability to seek favorable environmental conditions. We performed a partial Redundancy Analysis (pRDA) to quantify the variation in the macroinvertebrate community explained exclusively by (a) local predictors, (b) spatial predictors, and (c) landscape predictors or (d) the ensemble of all predictors. Our results indicate that aquatic macrophytes shape the structure of the macroinvertebrate metacommunity in floodplain lakes.
