“…Most studies on abandoned channels have focused on processes and patterns in the aquatic zone, particularly gradients of hydrological connectivity (Hudson et al, 2012;Phillips, 2013), sedimentation and geomorphological patterns (Bravard, 1982;Gagliano and Howard, 1984;Shields and Abt, 1989;Citterio and Piégay, 2009;Constantine et al, 2010;Delhomme et al, 2013;Dieras et al, 2013), impacts of nutrient load and hydrogeological fluxes (Bornette et al, 2001), and diversity of aquatic vegetation and animal communities (Amoros and Bornette, 2002;Obolewski, 2011;Besacier-Monbertrand et al, 2012;Meyer et al, 2013;Toth et al, 2013). However, the larger floodplain environment that develops as abandoned channels fill has received much less attention, in particular the composition, biodiversity and temporal changes of the terrestrial plant community and its distribution along hydrogeomorphic gradients (but see Shankman, 1993;Holland et al, 2000).…”

Macroinvertebrates are a crucial component of wetland trophic webs. Many taxa are used as bioindicators of ecosystem change. However, relationships between macroinvertebrates and the environmental factors in peat pool habitats are still not well recognized. The present study shows the results of long-term studies during the years 2010–2020, on the responses of macroinvertebrates to the changes of environmental variables in a peat pool habitat formed as a result of peat exploitation on continental raised bog. The RDA analysis significantly explained 87.3% of the variance in macroinvertebrates abundances. Assemblages of most taxa (Anisoptera, Chironomidae, Ceratopogonidae, Coleoptera, Hydrachnidia and Tabanidae) showed a strong relationship with N-NO3 and pH. Moreover, densities of Chaoboridae larvae were explained by chlorophyll-a concentrations. Dominant taxon, Chironomidae, constituted from 48% to 87% of total faunal density. The highest proportions showed larvae of Psectrocladius sp. (gr. sordidellus) and Chironomus sp. Changes in the composition of macroinvertebrate fauna over a period of 10 years reflect the eutrophication process of the peat pool and deterioration of habitat conditions.

“…Macrophytes also provide food (Kornijow 1996;Jones et al 2000) and shelter from predators (Crowder and Cooper 1982;Fisher et al 2012) to various epiphytic macroinvertebrates. The epiphytic macroinvertebrate community differs with attributes of the host macrophyte such as structural complexity (Taniguchi et al 2003; Van de Meutter et al 2008) and seasonal prevalence (Fontanarrosa et al 2013;Toth et al 2013). Therefore, it is important to consider the life form, density, and seasonality of macrophytes to elucidate their role in the ecosystem.…”

Water chestnut (genus Trapa) is an annual floating‐leaved macrophyte that produces dense beds known to drastically modify freshwater ecosystems. Although Trapa displays a distinct phenology that should alter the innate seasonal dynamics of ecosystems, the seasonality of these effects has rarely been investigated. Therefore, we examined seasonal changes in physicochemical conditions and assemblages of zoobenthos and zooplankton, and whether these changes were correlated with the rise and decline of dense beds of Trapa japonica in Lake Mikata, a temperate shallow lake in central Japan. Our results suggested that the formation of dense Trapa beds during summer resulted in hypoxia, which significantly decreased the abundance of Chironomidae and Oligochaeta in the benthic community, as well as that of Calanoida among zooplankton. When dense Trapa beds formed, we also detected growth of other taxa that were resistant to hypoxia, including Cladocera, Cyclopoida, Ostracoda, and Nematoda. Chlorophyll a concentration declined across the lake during summer, when dense Trapa beds formed. The decline in Trapa beds from autumn to spring resulted in increased dissolved oxygen concentration, chlorophyll a concentration, and invertebrate abundance (Chironomidae, Oligochaeta and Calanoida), as well as a decrease in taxa utilizing the dense Trapa beds. Our results suggest that the phenology of dense Trapa beds can drastically change the seasonal dynamics of physicochemical conditions and the lower components of the food web in a shallow lake ecosystem.
