“…Previous work (Bortolotti et al, 2016) suggests that shifts in wetland pH are biologically driven, primarily by SAV. Submersed and emergent vegetation has wellestablished direct and indirect effects on macroinvertebrate communities (Anteau & Afton, 2008;Hentges & Stewart, 2010) and such biotic interactions may be of greater importance than abiotic gradients in structuring prairie wetland macroinvertebrate communities (Hanson et al, 2005).…”

Summary Prairie pothole wetlands provide many ecosystem services, including supporting biodiversity and filtering water on the landscape. However, over half of these wetlands have been drained for agriculture, thereby requiring restoration to re‐establish ecosystem services. We assessed the recovery of hydrologically restored wetlands based on water chemistry and taxonomic shifts within and across five biological communities (phytoplankton, benthic diatoms, zooplankton, macroinvertebrates, submersed aquatic vegetation [SAV]). We sampled 24 wetlands in southeastern Saskatchewan, Canada, spanning three restoration states: recently restored (restored 1–3 years before the study; n = 8), older restored (restored 7–14 years before the study; n = 8) and natural (never drained; n = 8). Within approximately a decade of the re‐establishment of these previously drained wetlands, water chemistry, macroinvertebrate and SAV communities closely resembled those in natural wetlands. Here, total phosphorus and carbon dioxide concentrations declined, while salinity and pH increased, with time since restoration. No detectable differences in diatom and zooplankton communities persisted among the restored and natural sites; however, cyanobacteria were more representative of the restored wetlands Our findings suggest that hydrological restoration is an effective tool for re‐establishing baseline water quality and the capacity of prairie wetlands to support biodiversity across multiple trophic levels. However, given that there is a decadal lag in the re‐establishment of certain species, it is preferable to protect and retain intact wetlands on the landscape.

“…Our results are consistent with those findings. The amount of SAV in a wetland likely is positively correlated with the amount of food for amphipods because SAV produces coarse particulate organic matter and provides structure on which periphyton grow (Covich & Thorp, 1991;Hentges & Stewart, 2010). Although we did not detect an interaction between large fish and SAV, physical vegetative structure in wetlands also may make amphipods less susceptible to predation by fishes (Covich & Thorp, 1991;MacNeil et al, 1999) and concomitantly may allow amphipods to maintain high activity levels in the presence of predators (Wooster, 1998).…”

Fish and land use influence Gammarus lacustris and Hyalella azteca (Amphipoda) densities in large wetlands across the upper Midwest

Gammarus lacustris and Hyalella azteca (hereafter G. lacustris and H. azteca, respectively) are important components of secondary production in wetlands and shallow lakes of the upper Midwest, USA. Within the past 50 years, amphipod densities have decreased while occurrences of fish and intensity of agricultural land use have increased markedly across this landscape. We investigated influences of fish, sedimentation, and submerged aquatic vegetation (SAV) on densities of G. lacustris and H. azteca in semipermanent and permanent wetlands and shallow lakes (n = 283) throughout seven eco-physiographic regions of Iowa, Minnesota, and North Dakota during 2004-2005. G. lacustris and H. azteca densities were positively correlated with densities of SAV (P \ 0.001 and P \ 0.001, respectively). Both species were negatively correlated with densities of large fish (non-Cyprinidae; P = 0.01 and P = 0.013, respectively) and with high densities of fathead minnows (Pimephales promelas; P \ 0.001 and P = 0.033, respectively). H. azteca densities also were negatively correlated with densities of small fish (e.g., other minnows [Cyprinidae] and sticklebacks [Gasterosteidae]; P = 0.048) and common carp (Cyprinus spp.; P = 0.022). G. lacustris densities were negatively correlated with high levels of suspended solids (an index for sedimentation; P \ 0.001). H. aztecaHanding editor: Sonja Stendera E. Barry Moser is deceased. densities were positively correlated with the width of upland-vegetation buffers (P = 0.004). Our results indicate that sedimentation and fish reduce amphipod densities and may contribute to the current low densities of amphipods in the upper Midwest. Thus, removing/excluding fish, and providing a thick buffer of upland vegetation around wetlands may help restore amphipod densities and wetland and water quality within this landscape.

“…Fish presence is commonly identified as an important driver of aquatic macroinvertebrate community composition and diversity in wetlands (e.g. Hentges & Stewart, 2010;Hornung & Foote, 2006;Rennie & Jackson, 2005;Tangen et al, 2003;Zimmer, Hanson, & Butler, 2000). For example, a study of 19 semipermanently ponded wetlands in Minnesota observed that the presence/absence of fathead minnows was the most important factor in structuring aquatic invertebrate communities (Zimmer et al, 2000).…”

Pond permanence is a key determinant of aquatic macroinvertebrate community structure in wetlands

Globally, many aquatic ecosystems experience periodic desiccation that imposes stress on biota. The Northern Prairie Pothole Region (NPPR) in Alberta, Canada, contains abundant wetlands that fill with spring snowmelt and then draw down throughout the summer. They are often assigned a pond‐permanence class based on the duration of ponded water. These dynamic wetlands are home to diverse and productive communities of macroinvertebrates. We expected that pond permanence structures macroinvertebrate communities in NPPR wetlands. In addition to exploring the taxonomic composition of macroinvertebrate communities, we aimed to characterise these communities by functional groups to test for associations between pond permanence and desiccation strategies, feeding groups or behavioural guilds. We sampled aquatic macroinvertebrates from 87 wetlands in the NPPR that spanned a range of pond‐permanence classes. We identified macroinvertebrates to the lowest practical taxonomic level, usually family. We then performed multivariate analyses (multiresponse permutation procedures, non‐metric multidimensional scaling) to identify differences in community composition and functional groups among permanence classes. Community composition of macroinvertebrates was statistically distinct among pond‐permanence classes, with the extremes of temporarily‐ and permanently‐ ponded wetlands differing most. Notably, macroinvertebrates in temporarily‐ ponded wetlands were not unique taxa specially adapted to low‐permanence wetlands, but rather a subset of the community found in more permanent wetlands. In other words, macroinvertebrates at the family level exhibit a nested pattern of diversity best predicted by the permanence of ponded water in wetlands.
