“…Rock pools are common in aridlands with exposed impervious bedrock. Because these basins often occur in clusters, they represent a metacommunity with the individual basins varying in size, spatial arrangement, and potential for surface connectivity . Ranging in size from <1 to well over 1000 L, these habitats are subject to rapid filling and potential washout from seasonal, but sporadic, rains.…”

While ubiquitous, temporary waters vary greatly in geographic distribution, origin, size, connectivity, hydroperiod, and biological composition. However, all terminate as active habitats, transitioning into either dryness or ice, only to be restored when conditions improve. Hydroperiod in some temporary habitats is cyclical and predictable, while in others it is sporadic. Although the rotifer communities of temporary waters are subjected to unique selective pressures within their habitats, species share many of the same adaptive responses. Here, we review temporary waters and their rotiferan inhabitants, examining community composition, life history, and evolutionary strategies that allow rotifers to flourish in these fluctuating environments.Depressions in the landscape include interdunal ponds, playas (pans, vleys), pools in forests and shrublands (including Carolina Bays), prairie potholes, gueltas in desert regions, brackish coastal ponds, tree tip ups, and limestone turloughs. Depending on the local conditions, E. J. Walsh et al.

“…In addition, community dynamics are affected because rotifer dormant stages can undergo passive dispersal. As a result temporary waters are useful systems to test ecological theory , including metacommunity theory , dispersal theory , the effects of fragmentation on food web networks , and ecosystem processes in disturbed habitats .…”

“…Near habitats are more similar in community compositions than far habitats (Cottenie et al. ) and shorter distance among them allows for exchange of individuals between otherwise isolated communities or communities recovering from recurrent perturbations (Sciullo and Kolasa ). It is therefore possible that directly connected pools or pools connected by sufficiently high dispersal could experience population synchrony irrespective of specialization (habitat generalists and specialist).…”

“…Distance is often a proxy for dispersal in invertebrate communities as both live and dormant individuals disperse to nearby habitats by rain drop splashes, wind (Vanschoenwinkel et al 2008), direct water flow (Michels et al 2001, Van de Meutter et al 2006, or vector movement such as crabs. Near habitats are more similar in community compositions than far habitats (Cottenie et al 2003) and shorter distance among them allows for exchange of individuals between otherwise isolated communities or communities recovering from recurrent perturbations (Sciullo and Kolasa 2012). It is therefore possible that directly connected pools or pools connected by sufficiently high dispersal could experience population synchrony irrespective of specialization (habitat generalists and specialist).…”

The role of local and regional processes on population synchrony along the gradients of habitat specialization

Ecosphere 7(5):e01217. 10. 1002/ecs2.1217 Abstract. Metacommunity perspective highlights the role of space as a factor contributing to local community structure and dynamics. Often tests of metacommunity models rely on snapshot patterns of species distribution and abundance. Such patterns may introduce biases because they overlook differences in responses of constituent species to changing environmental conditions, particularly when such responses override patterns predicted from dispersal and biotic interactions alone. This applies, for example, to habitat generalists, whose responses to environmental variations differ from those of habitat specialists, resulting in different snapshot patterns at different times. Synchronized (i.e., correlated among sites) environmental variation is perhaps the most obvious case of environmental variation that could generate regular differences among species of different specialization. We hypothesized that synchronized environmental variation synchronizes local populations of habitat specialists to a greater degree than it does for habitat generalists as experiments have shown that habitat generalists are less sensitive to changing environmental conditions. To test this in an empirical system, we used time series data (nine annual surveys) on an invertebrate metacommunity of 49 rock pools on the coast of Jamaica. We found that population synchrony of a significant portion of 24 species sharing these rock pools increased with habitat specialization in response to environmental synchrony (represented by synchrony of environment). However, distance among rock pools, which may affect dispersal or shared perturbations, was negatively correlated with population synchrony of individual species, irrespective of their specialization. As only habitat specialists showed increasing synchrony with environmental synchrony, and both generalist and specialist synchrony were negatively correlated with distance, we infer that habitat generalists must be synchronized more by space-related processes while habitat specialists by a combination of environmental forcing and dispersal. Overall, the study suggests that species of different habitat specialization show consistent differences with respect to local processes involving environmental variations but show fewer differences with respect to regional processes involving distance, at least when long-term dynamics are concerned. Furthermore, the study identifies a rarely recognized link between variation in space and its consequences for variation in time-a link much more expressed among spatially restricted species such as habitat specialists.

“…Pools are refilled by rain, ocean spray and, for a few, by spring tides. The metacommunity hosts 79 invertebrate species which disperse as propagules by wind, ocean spray, animal vectors and overflow after heavy rains [28]. Species are divided among: Ostracods (21 species), copepods (nine species), cladocerans (three species), worms (16 species), aquatic insects (22 species) and other invertebrates (eight species).…”

The Long and Short of Biodiversity: Cumulative Diversity and Its Drivers

Long-term or cumulative diversity is the biodiversity that accumulates at a site over many generations of community members. Cumulative diversity is likely important to the intrinsic and functional value of ecosystems given the legacies left behind by many species. While its components—average short-term diversity (alpha) and temporal turnover (beta)—have been extensively studied, cumulative diversity itself has not. We therefore examined the environmental and community drivers of cumulative diversity with a novel hierarchical diversity partition. This partition breaks cumulative diversity into short-term, turnover, richness, and evenness components. We applied this framework to 49 tropical rock pool communities, censused over tens to hundreds of organism generations. Results uncovered two environmental regimes that differentially impacted the richness and evenness components of cumulative diversity: Occasional drying events mainly limited richness and reset communities, while less severe physicochemical variations reduced the evenness of communities. These causal pathways amount to differential controls on cumulative diversity; controls that can oppose each other to buffer diversity against change as well as create unexpected trade-offs for managers. We conclude that maintaining diversity at longer timescales requires new analytical tools and an expanded view that can account for its complexity.
