Spatiotemporal Assessment and Composition of Benthic Macroinvertebrate Communities in the Bermejo River Basin in the Ecuadorian Amazonia
The information includes biotic and ecological index data of benthic macroinvertebrates collected in the Ecuadorian Amazon Region. The biotic indexes are taxonomic abundance, richness, evenness, diversity, and dominance. The ecological indexes refer to the ecological water quality as determined by pollution-tolerant macroinvertebrates. The datasets also include physicochemical parameters for water quality determination. The dataset has been completed,; however, it may be updated if new information is generated.
Community structure of aquatic vertebrates and macroinvertebrates in relation to hydrologic variables in the Shark River Slough, Everglades National Park, Florida USA: Ongoing since 2012
The purpose of this project is to characterize the community structure of aquatic fauna (macroinvertebrates and fishes) and floating mats (including periphyton) across the heterogenous landscape of the NE Shark River Slough in Everglades NP. The community structure (abundance, biomass, and species composition) of floating mat, emergent vascular plants, fishes, and macroinvertebrates, and the spatial distribution of the latter in relation to hydrology, are among the key performance measures targeted for monitoring. The aim of our study is to provide a baseline characterization of these parameters so that the impact of future management activities (e.g., Modified Water Deliveries and Comprehensive Everglades Restoration Plan) can be assessed. The study area is sampled during the late wet season (September through November) to capture data when all sites are innundated with water and aquatic animal standing stocks are typically at their maximum. We document landscape-scale patterns in the NE Shark River Slough from this comprehensive sampling.

Representation of the standard deviation of vulnerability (SD-V) of the main food sources (FPOM, fine particulate organic matter; CPOM, coarse particulate organic matter; PT, plant tissue) calculated from the ratios recorded in the guts of the macroinvertebrates sampled in the elevational gradient of Gaira River during the dry and rainy seasons. Arrow thickness indicates the vulnerability importance.

Figure 6. Hierarchical classification of the sampling sites (a) and months (b) according to the relative abundance of macroinvertebrate taxa, using Noy-Meir clustering from generalized Euclidean distances. The sampling sites are coded as follows: 1 – VM1, 2 –VM2, 3 – VM3, 4 – VM4, and 5 – VM5. The months are coded as follows: 1 – July, 2 – August, 3 – October, and 4 – November.

Figure 8. CCA triplot (75 taxa, 14 samples, and 6 environmental factors) displaying 56% variance (first CCA axis, 31.4%; second CCA axis, 24.1%) in the WA (weighted averages) of taxa and species with respect to the environmental variables. Down-weighting of rare species was performed, and the WA algorithm was applied. The names of the taxa and species are abbreviated as follows: Hep fus – Kageronia fuscogrisea, Hep sp. – Heptagenia sp., Pot lut – Potamanthus luteus, Eph ign – Ephemerella ignita, Bae rho – Baetis rhodani, Hyd sp – Hydropsyche sp., etc. (full list of abbreviations is provided in the Appendix). The environmental factors are coded as follows: pH (pH), WTemp (water temperature), NH4 (ammonium ion), Organic N (organic nitrogen), TOC (total organic carbon), and Orthoph (orthophosphate). The samples are coded as in the Table (for example, 1- VM1_7, 2 – VM3_7, etc.).
