“…However, temporary pothole wetlands are likely to be more structurally similar to each other as they typically contain two vegetation zones (wet meadow and low prairie), whereas wetlands with longer hydroperiods can also support shallow and deep marsh zones as well as open water, each dominated by differing vegetation growth forms and canopy structures (Stewart and Kantrud 1971), though not necessarily by more species. More, macroinvertebrate diversity is influenced by vegetation microhabitat availability ) and bird communities are in turn influenced by both vegetation (Robichaud and Rooney 2017) and macroinvertebrate communities (Wrubleski and Ross 2011). To confirm that water and sediment quality were not more heterogeneous among temporary wetlands, we examined these environmental variables grouped by Figure 3.…”

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.

“…Southern Ontario is the most biodiverse region of Canada owing to its favorable climate and generally high soil fertility, as well as the local effects of various physio-geographic features (e.g., Great Lakes) and its location at the confluence of various biomes. It is undeniable that in some cases invasive species can lead to extreme changes to host communities across trophic levels (e.g., Robichaud & Rooney, 2017), economic losses (e.g., ECCC, 2012) and decline of valued native species (Pyšek & Richardson, 2010). There is no overall estimate available of costs and damages for all invasive species in Ontario, but the total impact of zebra mussel alone is estimated at up to $19 million annually (Marbek [Marbek Resource Consultants Ltd], 2010).…”

“…Monoculture emergent wetland (e.g, cattails, common reed) likely provided broods with escape cover. Monoculture wetlands are increasing in fresh water coastal wetlands of the Great Lakes and their functional value to wood ducks is worth further investigation (Wilcox et al 2003, Meyer et al 2010, Robichaud and Rooney 2017, Markle and Chow-Fraser 2018.…”

Survival and habitat selection during brood‐rearing influences reproductive success and waterfowl population dynamics. For effective management, it is important to understand vital rates and habitat choice range wide. We investigated survival and habitat selection of female wood ducks (Aix sponsa) and ducklings at Long Point, Lake Erie, Ontario, Canada in 2014. We captured incubating females (n = 40) in nest boxes and used radio‐telemetry to monitor survival and habitat use to 30 days post‐hatch. Four female mortalities occurred during brood‐rearing and apparent brood and duckling survival were 0.42 (85% CI = 0.33, 0.51) and 0.16 (85% CI = 0.14, 0.18), respectively. Duckling survival was negatively associated with brood size and distance of first movement, whereas survival was positively associated with precipitation. Successful brood‐rearing wood ducks selected forested wetlands and habitats that provided dense vegetative cover. Conservation and restoration of forested wetlands and similar cover should increase the availability of brood‐rearing habitat. Placement of nest boxes close to selected land cover types and strategies associated with reducing inflated clutch sizes may improve offspring survival. Our spatially explicit habitat selection model informs spatial prioritization of habitat conservation and nest box placement strategies within the Great Lakes region. © 2018 The Wildlife Society.
