“…Since we restricted our sampling of macroinvertebrates to wetlands with ponded water, we sampled fewer wetlands for macroinvertebrates than for plants and birds (Table 1). We sorted macroinvertebrates to family‐level resolution for most groups (Gleason and Rooney ). We based our sorting and Marchant box sub‐sampling protocol on the Canadian Aquatic Biomonitoring Network's laboratory methods (Environment Canada ), as described in Gleason and Rooney ().…”

“…All analyses were performed using R (<http://www.r-project.org>). Prior to calculating any diversity measures, we stratified our taxon abundance datasets by permanence class and subsampled by randomly selecting n sites using the R package fifer (Fife ), where n was the number of sites surveyed in our least intensively sampled permanence class (n = 14; Table 1). To ensure our diversity values were not overly influenced by this random subsampling, we repeated the process 1000 times, generating 3000 rarefied datasets detailing the abundance of each taxon observed at each wetland: 1000 datasets for plants, 1000 for birds and 1000 for macroinvertebrates.…”

“…We measured alpha and gamma diversity with the ‘H’ function in the vegan package (Oksanen et al ), using all 3000 rarefied datasets described above. We specified q, the diversity order, as taxa richness because the diversity measure and the numbers equivalent – the actual number of taxa that the diversity measure represents – are equal (Jost ).…”

Stochastic and deterministic processes drive wetland community assembly across a gradient of environmental filtering

The role of deterministic and stochastic processes in community assembly is a key question in community ecology. We evaluated the effect of an abiotic filter (hydroperiod) on the partitioned diversity of three taxonomic groups (birds, vegetation, macroinvertebrates) from prairie pothole wetlands in Alberta, Canada, which naturally vary in water permanence. We observed that alpha and gamma diversity were higher in permanent than temporary wetlands (16–25% and 34–47% respectively, depending on the taxon). This suggests an influence of deterministic constraints on the number of species a wetland can support. Taxa which cannot persist in shallow, temporary wetlands are excluded by the deterministic constraints that a shortened hydroperiod imposes. In contrast, we observed that beta diversity was significantly higher (2–12%) in temporary wetlands than permanent ones, and temporary wetlands supported more unique combinations of community composition than permanent wetlands, despite having a smaller regional species pool. This observation contradicts prior mesocosm studies that found beta diversity mirrored the pattern in gamma diversity along an environmental filtering gradient. We conclude that deterministic processes are more influential in more stable permanent wetlands, whereas stochastic processes play a more important role in assembly in dynamic temporary wetlands that must disassemble and re‐establish annually. Considering three distinct taxonomic groups differing in their relative mobility, our large‐scale field study demonstrates that both stochastic and deterministic processes act together to influence the assembly of multiple communities and that the relative importance of the two processes varies consistently along a gradient of environmental filtering.

In West Virginia, USA, there are 24 conservation easement program wetlands enrolled in the Agricultural Conservation Easement Program (ACEP). These wetlands are located on private agricultural land and are passively managed. Due to their location within fragmented agricultural areas, wetlands enrolled in ACEP in West Virginia have the potential to add wetland ecosystem services in areas that are lacking these features. We evaluated ACEP wetlands compared to reference wetlands on public land in West Virginia by using surrounding land cover, vegetative cover, and wetland features and stressors such as the presence or absence of erosion, upland inclusion, algal mats, and evidence of impacts from the surrounding landscape as surrogate measurements of wetland function on 13 ACEP wetlands and 10 reference wetlands. ACEP wetlands had higher percentages of tree coverage and a higher proportion of agricultural land in the areas immediately surrounding the wetland. Reference wetlands had higher percent coverage of emergent vegetation and had a higher proportion of forest in the immediate landscape. Our findings suggest that ACEP wetlands provide valuable early successional and forested wetland cover in a state that is largely forested. Because of this, it is important to maintain and even expand ACEP in West Virginia to continue providing a valuable source of early successional wetland habitat.

Functional dispersion of wetland birds, invertebrates, and plants more strongly influenced by hydroperiod than each other

The relative role of biological and abiotic filters in the assembly of co-occurring taxa is of broad interest to ecologists. While some authors point to biological interactions (e.g., competition) as the stronger driver of ecological selection, others assert that abiotic conditions are more important because they filter species at the regional level. Because communities influenced by a dominant abiotic filter (e.g., Prairie Pothole Region [PPR] wetlands, each varying in their ponded water permanence) often have strong cross-taxon relationships, we can study these communities to better understand the relative influence of abiotic versus biotic filters on community structure. Using functional dispersion as our measure of communities, we test six alternate hypotheses about the relative importance of various pathways representing influence of biological and permanence filters on birds, aquatic macroinvertebrates, and wetland plants in the northwest PPR using structural equation modeling. We aimed to understand whether (1) ponded water permanence alone explained functional dispersion; (2) the influence of permanence on functional dispersion was direct or mediated; and (3) abiotic filtering by permanence was stronger than biotic filtering by co-occurring taxa. The best model suggests that there is a direct influence of permanence on the functional dispersion of each taxonomic group and that both bird and macroinvertebrate functional dispersion are causally related to plant functional dispersion, though for invertebrates, the influence of plants is much less than that of permanence. Thus, the relative importance of wetland permanence and the functional dispersion of co-occurring taxa depend on which taxon is considered in PPR wetlands.
