Variations in Benthic Macroinvertebrate Communities and Biological Quality in the Aguarico and Coca River Basins in the Ecuadorian Amazon

“…The elevation ranges might be also considered as an influential variable as the longitudinal gradient of the river is affected by upstream locations and surrounding land use [81]. In short, our results are in line with the findings of previously reported research, which shows that these variables are not only important for taxonomic diversity but also influence functional diversity [20,[82][83][84].…”

“…The use of the biological traits has often provided a structured understanding of the anthropogenic stressors impacts [101], enabling the comparison of species groups from different systems and assemblages [7]. For instance, in this study, they indicate how feeding habits are directly associated with the metabolic resources that individuals need and, therefore, to the dominant productivity pathways that operate in a given water space, such as primary or secondary productivity, as also explained by the RCC [49,82,102]. Nevertheless, some challenges associated with the application of traits are the low taxonomical resolution of the data (often family), a general lack of autecological knowledge for many taxa [4,103], and the absence of a standardized methodology for trait allocation in this specific Ecuadorian Amazon region [36].…”

Integrating measures of ecosystem structure and function to improve assessments of stream integrity

“…For example, the trait-based SPEAR approach as applied by van der Lee et al ( 2020) seems promising in diagnosing potential causes of adverse effects. Also, important functions of ecosystem components could be identified from structural attributes by using traits as shown by the study of de Brouwer et al (2020). On the other hand, more complete knowledge is required of the functional performance of organisms.…”

Evaluation of the Relationship between Stream Habitat Quality and Taxa and Trait Richness and Diversity in Piedmont Streams in North Carolina

“…Gregory [91] and Wang et al [92] found that taxa richness of benthic macroinvertebrates was slightly higher on woody debris than in riffles but had lower densities of organisms. Large woody debris can increase stream habitat complexity by altering the flow path in a stream, resulting in the formation of pools, exposure of gravel and cobble substrates, enhancement of sediment deposition, an increase in the retention of leaves and other organic debris, and the provision of stable substrates for benthic macroinvertebrates and periphyton [93][94][95][96][97][98]. Large woody debris serves as refugia for fish and benthic macroinvertebrates during high flows as well as a stable substrate for both benthic macroinvertebrates and periphyton [88,93,99].…”
