“…Thus, it is at intermediate dispersal rates that the geographic isolation gradient of communities may play the most important role in determining biodiversity (e.g., Fortuna et al, 2006;Economo and Keitt, 2010;Cañedo-Argüelles et al, 2015). Notably, we have no clear understanding of how the spatial structure of a real landscape interacting with species dispersal abilities may determine metacommunity biodiversity at intermediate dispersal rates (Hillebrand et al, 2018;Thompson et al, 2020;Bauer et al, 2021;Fortin et al, 2021;Suzuki and Economo, 2021).…”

Heterogeneity in the isolation of patches may be essential for the action of metacommunity mechanisms

The spatial isolation gradient of communities and the gradient in the species dispersal ability are recognized as determinants of biodiversity in metacommunities. In spite of this, mean field models, spatially explicit models, and experiments were mainly focused on idealized spatial arrangements of communities leaving aside the combining role of dispersal and isolation gradients in metacommunity processes. Consequently, we have an incipient understanding of the role of the real spatial arrangement of communities on biodiversity patterns. We focus on six metacommunities for which confident information about the spatial arrangement of water bodies is available. Using coalescent metacommunity models and null models that randomize the location of water bodies, we estimated the potential effect of the landscape on biodiversity and its dependence on species dispersal ability. At extremely low or high dispersal abilities, the location of ponds does not influence diversity because different communities are equally affected by the low or high incoming dispersal. At intermediate dispersal abilities, peripheral communities present a much lower richness and higher beta diversity than central communities. Moreover, metacommunities from real landscapes host more biodiversity than randomized landscapes, a result that is determined by the heterogeneity in the geographic isolation of communities. In a dispersal gradient, mass effects systematically increase the local richness and decrease beta diversity. However, the spatial arrangement of patches only has a large importance in metacommunity processes at intermediate dispersal abilities, which ensures access to central locations but limits dispersal in isolated communities. The ongoing reduction in spatial extent and simplification of the landscape may consequently undermine the metacommunity processes that support biodiversity, something that should be explicitly considered in preserving and restoring strategies.

“…Secondly, we need to acknowledge that other mechanisms besides environmental filters also affect community assembly (Cadotte & Tucker, 2017), which were not specifically addressed here. Namely, biotic interactions might contribute greatly to the assembly of ecological communities (Bauer et al, 2021), particularly through species sorting at small spatial scales resulting in trait divergence, that is, an increase in FD (Weiher & Keddy, 1995). Thus, we would expect the greatest contribution of biotic interactions to the patch‐to‐object step.…”

“…Such filters can act at different spatial scales (Jiménez‐Alfaro et al, 2018), ranging from small‐scale microhabitat conditions and priority effects during microhabitat colonisation (Song et al, 2017) up to landscape‐scale or even continental and global scale factors (Harmon‐Threatt & Ackerly, 2013; Mori et al, 2018). Thus, the assembly of local communities can be framed as a process of several hierarchical filtering events (Bauer et al, 2021). Studies addressing community assembly as a multi‐scale process indicate the role of different mechanisms acting at different scales (e.g.…”

Hierarchical trait filtering at different spatial scales determines beetle assemblages in deadwood

1. Environmental filters-including those resulting from biotic interactions-play a crucial role during the assembly of ecological communities. The importance of scale has thereby been acknowledged but filters at different scales have rarely been quantified in relation to each other, although these hierarchically nested filters eventually determine which communities assemble from a regional species pool.2. Saproxylic beetles offer an ideal system to study such hierarchically nested environmental filters. Three steps of filtering during the community assembly of these deadwood-dependent beetles are proposed. First, starting from a regional species pool, species must disperse to forest sites. Second, within a site, individuals need to find a patch with preferred microclimatic conditions. Third, the conditions of a single deadwood object (i.e. tree species identity, decomposition stage) at this patch will determine, which species colonise and establish.3. To study these hierarchical filters, we used unique long-term data ets of saproxylic beetle diversity from trap catches at 29 sites and from emergence traps on 694 experimentally installed deadwood logs at the same sites in three regions in Germany. To relate different environmental filters to beetle assemblages, we used a set of 13 functional traits that are hypothesised to relate to different filters at different scales.4. We show that all three hierarchical filtering steps resulted in reductions of functional diversity and simultaneous shifts in the functional composition of beetle assemblages, reflecting the roles of different traits in response to different

“…A framework was developed using functional trait dimensions of trophic metacommunities for a more unified approach on metacommunity ecology across trophic levels (Bauer et al, 2021). This streamlined approach in combination of the elements of SCO infrastructure will be utilized for upcoming research questions, e.g., understanding how dispersal and competition processes form the typical salt marsh zonation and how these communities will respond to the changing environment (Bearup and Blasius, 2016;Balke et al, 2017;Redelstein et al, 2018b).…”

Coastal observatories are key to improve the understanding of processes within the coastal area and their interactions with regional and global environmental changes. The land-sea transition zone is an essential area that allows research on unique scientific questions under anthropogenic and natural influences. Amid the Wadden Sea UNESCO world natural heritage site – the largest tidal flat region worldwide – the barrier island Spiekeroog is an excellent location for an observatory studying land-sea interactions. The integrated Spiekeroog Coastal Observatory (SCO) operated by the Institute for Chemistry and Biology of the Marine Environment (ICBM, University of Oldenburg) is dedicated to interdisciplinary marine and terrestrial ecosystem research. Its position within the tidal area and the multitude of research-field addressed establishes the SCO as a unique coastal observatory with the potential to identify patterns in long-term variability and simultaneously understanding short-term changes. The establishment of the Time-Series Station (TSS) Spiekeroog in a tidal channel west of Spiekeroog back in 2002 laid the foundation of the SCO. Since then, the observatory is expanding continuously and is now representing a valuable asset supporting education, industry, government, and environmental conservation efforts in the area. Summing up the infrastructure and technical components, the importance of the SCO is evident, and individual projects greatly benefit from the collaboration with the partners in and the elements of the SCO. Harmonizing the infrastructure and competences of contributing partners will be a next step to further consolidate the SCO. A challenge poses the maintenance of the SCO based on projects, which is focused on the addition of new facilities, not maintaining, refurbishing, or (if necessary) deconstructing existing infrastructure. Therefore, structural support and funding opportunities not linked to projects but aiming to sustain observational capacities are required.
