“…However, the present study noted a dominance of nauplii and copepodites and Rotifera from the families Brachionidae and Lecanidae. These results support those by other studies conducted in the Amazon region (Bozelli 1992; Costa et al 2016a, b) and Brazil (Branco and Cavalcanti 1999; Branco and Senna 1996; Lucinda et al 2004; Matsumura-Tundisi and Tundisi 2005; Negreiros et al 2010; Pinto-Coelho 1998; Sendacz et al 2006).…”

The port regions of the Amazon are subject to environmental impacts high shipping traffic. In October 2015, a cargo ship containing 5000 oxen sank in the Port of Vila do Conde, northern Brazil, releasing large amounts of organic matter and diesel oil into the aquatic environment. We evaluated the consequences of this shipwreck on the zooplankton community. Sampling was carried out using a phytoplankton net (64 μm) at two locations close to the port. We calculated the frequency of occurrence, relative abundance, and trophic state index and performed a canonical redundancy analysis of zooplankton in this area. Total density values ranged from 371 to 8600 organisms/m 3 , with minimum values being recorded during the period of the shipwreck and maximum values after the shipwreck. The areas categorized as super eutrophic had the lowest density values. The most abundant species/groups were nauplii and copepodites of the orders Cyclopoida and Calanoida. Of the environmental variables, only biochemical oxygen demand, chemical oxygen demand, and total dissolved solids were selected by the redundancy canonical analysis. The environmental conditions of the region and the ongoing environmental impacts might substantially influence the structure of the zooplankton community. The predominance of these organisms, in addition to the high densities of nauplii and copepodites, was likely related to the large amounts of nutrients generated by the shipwreck.

“…Costa et al ( 2016a ) evaluated a region close to our study area and observed higher values of the recorded species/organisms (149 species/organisms, compared with 84 in the present study). However, the present study noted a dominance of nauplii and copepodites and Rotifera from the families Brachionidae and Lecanidae.…”

“…As biological communities such as zooplankton play an essential role in aquatic food webs and exhibit strong and rapid responses to environmental pollution (Costa, Pinheiro, Amado, & de Oliveira Lima, 2016;Yang et al, 2017), they are usually used to infer environmental conditions and ecosystem functioning in polluted aquatic ecosystems (Fermani et al, 2013;Palmer & Yan, 2013;Xiong, Li, Chen, et al, 2016;Xiong, Ni, Chen, et al, 2017). Great efforts on morphological identification have been made to investigate biodiversity of microscopic zooplankton, and such efforts have provided a critical impetus for zooplankton ecology research, unmasking the crucial ecological roles of zooplankton in aquatic ecosystems (e.g., Bertani, Ferrari, & Rossetti, 2012;Lair, 2006;Xiong, Li, Chen, et al, 2016;Xiong, Ni, Chen, et al, 2017).…”

The degradation of freshwater ecosystems has become a common ecological and environmental problem globally. Owing to the complexity of biological communities, there remain tremendous technical challenges for investigating influence of environmental stressors (e.g., chemical pollution) on biological communities. High-throughput sequencing-based metabarcoding provides a powerful tool to reveal complex interactions between environments and biological communities. Among many technical issues, the clustering strategies for operational taxonomic units (OTUs) which are crucial for assessing biodiversity of communities, may affect final conclusions. Here, we used zooplankton communities along an environmental pollution gradient in the Chaobai River in Northern China to test different clustering strategies, including nonclustering and clustering with varied thresholds. Our results showed that though the number of OTUs estimated by nonclustering strategies and clustering strategies with divergence thresholds of 99%-97% largely varied, they were able to identify the same set of significant environmental and spatial variables responsible for geographical distributions of zooplankton communities. In addition, the ecological conclusions obtained by clustering thresholds of 99%-97% were consistent with nonclustering strategies, where for all eight clustering scenarios we detected that species sorting predicted by environmental variables overrode dispersal as the dominant factor in structuring zooplankton communities. However, clustering with the divergence thresholds of <95% affected the environmental and spatial variables identified. We conclude that both newly developed nonclustering methods and traditional clustering methods with divergence thresholds ≥97% were reliable to reveal mechanisms of complex community-environment interactions, although different clustering strategies could lead to largely varied biodiversity estimates such as those for α-diversity.

“…Effects of environmental impacts on aquatic biota at the Vila do Conde Industrial Pole were evaluated by some studies addressing plankton (phyto-and zooplankton) and ichthyofauna. Regarding plankton, changes in density of organisms, and a higher frequency of impacting species were observed in the areas closest to the port system (SENA et al, 2015;COSTA et al, 2016a;2016b;PINHEIRO et al, 2019). In the ichthyofauna, in places close to the IPC, there was a reduction in the diversity of species and food guilds (VIANA; FRÉDOU; FRÉDOU, 2012; VIANA; FRÉDOU, 2014), in addition to a higher incidence of individuals with histopathological damage (VI-ANA et al, 2013).…”

The study characterized and evaluated the use of the benthic macroinvertebrate community as an indicator of impacts in different estuarine environments around the Industrial Port Complex (IPC) of Vila do Conde (Pará State, Amazon region). Fauna of beaches and rivers, in sectors of the estuary under different degrees of environmental impact (high, medium, and low), was compared in different seasonal periods. Macrofauna was composed of typically fresh-water and estuarine groups. Beaches presented sediment with a texture ranging from medium to coarse sand, with a less rich macrofauna ( = 4.5 ± SE 0.3 taxa/sample) and dense ( = 1,838.1 ± 164.8 ind./m2) of organisms when compared to rivers ( = 5.9 ± 0.3 taxa/sample, and 3,248.9 ± 77.0 ind./m2), which were environments more muddy. For both environments, sites in the high-impact sector were less rich ( = 4.7 ± 0.3 taxa/sample) and dense ( = 2,812.9 ± 232.7 ind./m2) when compared to those in the low-impact sector ( = 7.6 ± 0.4 taxa/sample, and 3,314.3 ± 230.1 ind./m2). Richness ( = 6.4 ± 0.3 taxa/sample) and density ( = 3,859.4 ± 190.2 ind./m2) were higher in the rainier season when compared to the less rainy season ( = 4.8 ± 0.3 taxa/sample, and 1,933.0 ± 172.1 ind./m2). However, there were no significant seasonal changes in composition. Results indicated that the structure of the benthic macroinvertebrate community surrounding the IPC responds to the loss of environmental quality, with extreme effects of a drop in abundance and diversity. Taxa that are more tolerant (Namalycastis caetensis, Cirolana sp., Pseudosphaeroma sp., Tubificidae, and Chironomidae) and sensitive (Hydropsychidae and Eteone sp.) to impact conditions were identified and evaluated as potential bioindicators.
