The efficiency of biodiversity assessments and biomonitoring studies is commonly challenged by limitations in taxonomic identification quantification approaches. In this study, we assessed the effects different numerical resolutions on a range community structure metrics invertebrate compositional data sets from six regions distributed across North South America. We specifically degree similarity (richness, equitability, beta diversity, heterogeneity composition congruence) for identified to...
Abstract Estimating organisms' responses to environmental variables and taxon associations across broad spatial scales is vital for predicting their climate change. Macroinvertebrates play a major role in wetland processes, but studies simultaneously exploring both community structure trait gradients are still lacking. We compiled global dataset (six continents) from 756 depressional wetlands, including the occurrence of 96 macroinvertebrate families, phylogenetic tree, 19 biological traits....
ABSTRACT Measurements of biodiversity are crucial to assessing the ecological integrity ecosystems. However, adequately describing range organisms existing in habitats can be challenging, especially for taxonomically rich invertebrates. We analysed six large datasets designed describe taxonomic richness aquatic invertebrate assemblages depressional freshwater wetlands from various regions or locations (in North America, southern Africa and South America). Three targeted numbers (57–163...
Abstract Alternative stable states are nontransitory within which communities can exist. However, even highly dynamic be viewed the framework of stable‐state theory if an appropriate “ecologically relevant” time scale is identified. The ecologically relevant for systems needs to conform amount needed a system's community complete entire cycle through its normal range variation. For some systems, period relatively short (eg, tidal systems), others it decadal prairie wetlands). We explore...
Interactions between climate and hydrogeologic settings contribute to the hydrologic chemical variability among depressional wetlands, which influences their aquatic communities. These interactions resulting have led inconsistent results in terms of identifying reliable predictors aquatic-macroinvertebrate community composition for wetlands. This is especially true Prairie Pothole Region North America where, addition pronounced variability, studies are often confounded by fish introductions....

Abstract Analyses of biota at lower latitudes may presage impacts climate change on higher latitudes. Macroinvertebrate assemblages in depressional wetlands be especially sensitive to because weather‐related precipitation and evapotranspiration are dominant ecological controls habitats, organisms temperature‐sensitive ectotherms. We aimed better understand how wetland macroinvertebrate were structured according geography climate. To do so, we contrasted aquatic‐macroinvertebrate assemblage...
Wetland ecosystems are diverse, productive habitats that essential reservoirs of biodiversity. Not only they home to numerous wetland-specialist species, but also provide food, water, and shelter support terrestrial wildlife populations. However, like observed patterns biodiversity loss, wetland have experienced widespread loss degradation. In order conserve restore wetlands, thereby the support, it is important understand how in maintained. Habitat heterogeneity connectivity thought be...
The homogenization of freshwater ecosystems and their biological communities has emerged as a prevalent concerning phenomenon because the loss ecosystem multifunctionality. millions prairie-pothole wetlands scattered across Prairie Pothole Region (hereafter PPR) provide critical functions at local, regional, continental scales. However, an estimated 50% historical widespread conversion grasslands to cropland make PPR heavily modified landscape. Therefore, it is essential understand current...

Barred tiger salamanders [Ambystoma mavortium (Baird, 1850)] exhibit two trophic morphologies; a typical and cannibalistic morph. Cannibalistic morphs, distinguished by enlarged vomerine teeth, wide heads, slender bodies, tendencies, are often found where conspecifics occur at high density. During 2012 2013, 162 North Dakota wetlands lakes were sampled for salamanders. Fifty-one contained A. populations; four of these morph individuals. Two populations with morphs occurred sites abundances...
