“…This suggests harsh climate conditions filter some groups, but those adapted for the conditions can proliferate. For example, the diversity of large branchiopods (fairy shrimps, clam shrimps, tadpole shrimps) tends to be greatest in wetlands with harsh environmental conditions (see Boix and Batzer ).…”

Understanding global ecological patterns and processes, from biogeochemical to biogeographical, requires broad‐scale macrosystems context for comparing and contrasting ecosystems. Climate gradients (precipitation and temperature) and other continental‐scale patterns shape freshwater environments due to their influences on terrestrial environments and their direct and indirect effects on the abiotic and biotic characteristics of lakes, streams, and wetlands. We combined literature review, analyses of open access data, and logical argument to assess abiotic and biotic characters of freshwater systems across gradients of latitude and elevation that drive precipitation, temperature, and other variability. We explored the predictive value of analyzing patterns in freshwater ecosystems at the global macrosystems scale. We found many patterns based on climate, particularly those dependent upon hydrologic characteristics and linked to characteristics of terrestrial biomes. For example, continental waters of dry areas will generally be widely dispersed and have higher probability of drying and network disconnection, greater temperatures, greater inorganic turbidity, greater salinity, and lower riparian canopy cover relative to areas with high precipitation. These factors will influence local community composition and ecosystem rates. Enough studies are now available at the continental or global scale to start to characterize patterns under a coherent conceptual framework, though considerable gaps exist in the tropics and less developed regions. We present illustrative global‐scale trends of abiotic, biotic, and anthropogenic impacts in freshwater ecosystems across gradients of precipitation and temperature to further understanding of broad‐scale trends and to aid prediction in the face of global change. We view freshwater systems as occurring across arrays of multiple gradients (including latitude, altitude, and precipitation) rather than areas with specific boundaries. While terrestrial biomes capture some variability along these gradients that influence freshwaters, other features such as, slope, geology, and historical glaciation also influence freshwaters. Our conceptual framework is not so much a single hypothesis as a way to logically characterize patterns in freshwaters at scales relevant to (1) evolutionary processes that give rise to freshwater biodiversity, (2) regulatory units that influence freshwater ecosystems, and (3) the current scope of anthropogenic impacts on freshwaters and the vital ecosystem services they provide.

“…Apparently mountain wetland invertebrates are vulnerable to climate change effects (Rosset et al., 2010; Rosset & Oertli, 2011). Additionally, the naturally harsh environments in wetlands for macroinvertebrates act to filter the set of organisms that can exploit the habitats (Boix & Batzer, 2016; Wissinger, 1999), which likely makes the habitats resistant to outside macroinvertebrate invaders. While minimal evidence exists on exotic macroinvertebrates successfully establishing in freshwater wetlands, there is evidence from alpine and austral wetlands that native macroinvertebrate species from lower elevations/latitudes may be now establishing at higher elevations/latitudes, with possible impacts on the high‐elevation/latitude fauna (Jara & Perotti, 2018; Wissinger et al., 2016).…”

Analyses of biota at lower latitudes may presage impacts of climate change on biota at higher latitudes. Macroinvertebrate assemblages in depressional wetlands may be especially sensitive to climate change because weather-related precipitation and evapotranspiration are dominant ecological controls on habitats, and organisms of depressional wetlands are temperature-sensitive ectotherms. We aimed to better understand how wetland macroinvertebrate assemblages were structured according to geography and climate. To do so, we contrasted aquatic-macroinvertebrate assemblage structure (family level) between subtropical and temperate depressional wetlands of North and South America using presence-absence data from 264 of these habitats across the continents and more-detailed relative-abundance data from 56 depressional wetlands from four case-study locations (North Dakota and Georgia in North America; southern Brazil and Argentinian Patagonia in South America). Both data sets roughly partitioned wetland numbers equally between the two climatic zones and between the continents. We used ordination methods (PCA and NMDS) and tests of multivariate dispersion (PERMDISP) to assess the distribution and the homogeneity in variation in the composition of macroinvertebrate assemblages across climates and continents, respectively. We found that macroinvertebrate assemblage structures in the subtropical depressional wetlands of North and South America were similar to each other (at the family level), while assemblages in the North and South American temperate wetlands were unique from the subtropics, and from each other. Tests of homogeneity of multivariate dispersion indicated that family-level assemblage structures were more homogeneous in wetlands from the subtropical than the temperate zones. Our study suggests that ongoing climate change may result in the homogenization of macroinvertebrate assemblage structures in temperate zones of North and South America, with those assemblages becoming enveloped by assemblages from the subtropics. Biotic homogenization, more typically associated with other kinds of anthropogenic factors, may also be affected by climate change.

“…As ectothermic organisms, many life-history aspects important to the local performance of insects in temporary ponds (desiccation tolerance, growth and emergence patterns, flight initiation) are dependent on climate (Boix et al 2011;Kingsolver et al 2011). Thus, climate gradients are key drivers of the spatial distribution of wetland insects (Boix & Batzer 2016). The composition of wetland insect communities was indeed found to vary along climate gradients (Batzer et al 2005;Ruhí et al 2013Ruhí et al , 2014Pires et al 2018;Epele et al 2019).…”

“…This apparent inconsistency can be a result of the dynamic nature of intermittent ecosystems (Datry et al 2016). That is, the relative importance of assembly processes in ponds can vary over their hydrological cycle (Boix & Batzer 2016;Datry et al 2016).…”

The role of environmental and spatial factors in the assembly of aquatic insect communities in southern Brazilian temporary ponds

Metacommunity organisation in temporary ponds is assembled by spatiotemporally varying processes that are also contingent on the species' dispersal ability and scale of observation. Aquatic insects are useful models to study the relative contribution of environmental and spatial factors to community assembly in view of the differing dispersal ability existing in the species from this group. We assessed the metacommunity organisation of aquatic insects and subsets of strong-and weak-flying insects in relation to environmental (habitat structure; water chemistry; climate) and spatial factors in temporary ponds ranging along a latitudinal gradient in southern Brazil. Local and climate environmental factors (water chemistry and temperature) along with fine-scale spatial factors were the main drivers of the total insect community, although their relative importance shifted between subsets of weak-and strong-flying insects. The composition of strong-flying insects was structured by climate and fine-scale spatial factors, while weak-flying insects, by local (water chemistry) and spatially structured climate. This suggests that strong-flying insects showed stronger signatures of mass effects at finer scales, while weak-flying insects were more strongly affected by species sorting coupled to local environmental factors and regional climate. In summary, our results indicate that the relative importance of assembly processes for metacommunity organisation of aquatic insects in temporary ponds is contingent on dispersal ability.
