Aquatic macrophyte and macroinvertebrate diversity and conservation in wetlands of the Sinos River basin

Abstract: Wetlands are important sites for biological conservation because they support rich biodiversity and present high productivity. Species-area relationship is an important tool in conservation planning and it has been extensively used for wetland management. This study had as aims: (1) to analyse macrophyte and macroinvertebrate diversity in the fragmented wetlands of the Sinos River basin; and (2) to investigate whether wetland areas could work as a tool for selecting the important habitats for biodiversity cons… Show more

“…Chironomidae was also frequently consumed across the seasons, with positive selection indexes in all collections. Studies have shown that Chironomidae is extremely abundant in subtropical wetlands (Stenert et al 2008;Maltchik et al 2010b), becoming a significant food item to C. fulgens. Although Dogielinotidae was the most abundant taxon in the study wetlands through the seasons each year, C. fulgens showed a positive selective value only when the fishes were adult (spring).…”

“…Estudos demonstram que a área é um forte preditor para a riqueza e composição de espécies de invertebrados (Brönmark, 1985;Stenert & Maltchik, 2007), porém isso não é uma constante, pois sistemas pequenos heterogêneos estruturalmente podem manter um grande número de espécies de moluscos (Oertli et al, 2002) e outros invertebrados (Maltchik et al 2010b). A habilidade de suportar variações no nível da água também interfere na presença de espécies em sistemas com hidroperíodos sazonais (Kretzschmar & Heckman, 1995;Junk & Robertson, 1997) e esta habilidade difere entre grupos (bivalves e gastrópodes) e espécies de moluscos a depender de sua constituição morfofisiológica.…”

“…Studies of aquatic plant species in the native South American range of water primroses have largely focused on floristic surveys, composition, structure, and successional dynamics of vegetation that includes Ludwigia spp. in wetland areas of southern Brazil (Rolon et al 2008, Maltchik et al 2010 and in the Paraná River watershed (Sabattini and Lallana 2007). In southern Brazil, L. peploides is a member of wetland plant communities with high diversity of macrophyte and -macroinvertebrate species (Maltchik et al 2010).…”

In southern Brazil, L. peploides is a member of wetland plant communities with high diversity of macrophyte and -macroinvertebrate species (Maltchik et al 2010). The expansive Paraná River watershed is a dynamic, lentic system characterized by recurring flood pulses over short temporal scales that reset successional processes in the river system (Sabattini and Lallana 2007).…”
