Influence of Sieve Mesh Size on Relationships between Macroinvertebrate Assemblage and Environmental Variables in Wetlands

Can nesting waterbirds influence the community structure of macroinvertebrates in southern Brazilian intermittent wetlands?

“…Richness was negatively influenced by water turbidity and total dissolved solids, and the composition was influenced by water temperature, oxidation-reduction potential, turbidity, sediment organic matter, and orthophosphate. Many studies detected relationships between water physicochemical variables and macroinvertebrate communities in wetlands (Zimmer et al, 2000;Batzer et al, 2004;Stenert & Maltchik, 2007;Stenert et al, 2008;Tokeshi & Arakaki, 2012;Bischof et al, 2013;Strachan et al, 2015;Barros et al, 2016;Gleason & Rooney, 2017;Romero et al, 2017;Baldwin et al, 2018). Some authors detected reductions in macroinvertebraterichness with increasing turbidity (Batzer, 2013;Johnson et al, 2013;Sundberg et al, 2016;Baldwin et al, 2018).…”

Some authors detected reductions in macroinvertebraterichness with increasing turbidity (Batzer, 2013;Johnson et al, 2013;Sundberg et al, 2016;Baldwin et al, 2018). Elevated turbidity is associated with a higher number of suspended organic and inorganic matter in the water, usually due to the allochthonous material input and the sediment stirring (Gonçalves et al, 2012;Davies-Colley & Smith, 2001;Karna et al, 2015), which can significantly impact the aquatic biota (Bilotta & Brazier, 2008), including the macroinvertebrate community (Jones et al, 2012).…”

“…The aquatic macroinvertebrate community is represented by different taxonomic groups that live all or part of their life cycles in freshwater habitats (Metcalfe, 1989;Baldwin et al, 2018). The community structure of aquatic macroinvertebrates is sensitive to many local environmental factors (Batzer et al, 2004;Stenert et al, 2008;Romero et al, 2017;Baldwin et al, 2018).…”

Macroinvertebrate composition in subtropical intermittent wetlands is strongly affected by seasonal changes related either with climate or variation in water availability, as hydroperiod can either constrain the establishment of many taxa or affect water-level environmental conditions (Stenert & Maltchik, 2007;Batzer, 2013;Gleason & Rooney, 2017).…”

“…Aquatic macroinvertebrates are key elements of the ecological dynamics of wetlands, linking producers and higher-level consumers such as waterbirds (Metcalfe, 1989;Baldwin et al, 2018). Macroinvertebrates comprise a major part of the food items of waterbirds (Meyer et al, 2015), supplying proteins and other essential nutrients for their survival (Anderson & Smith, 2000;Baldassarre & Bolen, 2006).…”
