Data from: Influence of abiotic and biotic factors on benthic marine community composition, structure and stability: a multidisciplinary approach to molluscan assemblages from the Miocene of northern Germany
<p><span>The Miocene mica-clay deposits of Groß Pampau (northern Germany) are well known for their diverse assemblages of marine mammals, particularly whales. Despite numerous systematic and biostratigraphic studies, an in-depth palaeoecological analysis of its diverse molluscan assemblages and a comprehensive palaeoenvironmental reconstruction are lacking. Here, we integrated new faunal, sedimentological, and geochemical data to reconstruct the marine palaeo-ecosystem of the late Miocene sedimentary succession of Groß Pampau, and to identify the drivers controlling the composition, ecological structure and temporal dynamics of its macrobenthic molluscan assemblages. Fossil evidence, coupled with analyses of clay mineral composition, grain size distribution, and geochemical data (total organic carbon, total nitrogen, δ<sup>13</sup>C, δ<sup>18</sup>O, δ<sup>15</sup>N of sediment and shells), suggest a warm-temperate, mesotrophic, low-energy, offshore marine setting mostly below storm wave base and a pronounced surface-to-bottom water temperature gradient. Low variability in sedimentological and geochemical signals indicates generally stable physico-chemical conditions, whereas occurrences of opportunistic species (<em>Varicorbula</em> <em>gibba</em>) point at </span><span>occasionally less favourable bottom conditions, possibly related to transient hypoxia</span><span>. Canonical correspondence analysis reveals that the distribution of molluscan assemblages correlates with total organic carbon and nitrogen content, suggesting organic matter availability at the seafloor as a controlling factor. A pattern of repetitive punctuated stasis of molluscan assemblages is defined by the temporal persistence in taxonomic and ecological composition, occasionally interrupted by shifts to a different faunal configuration. We suggest that both stable environmental conditions and biotic interactions, i.e. the top-down control exerted by carnivorous gastropods and environmental modification by ubiquitous burrowing deposit feeders, probably contributed to the observed temporal stability. Whereas comparison with Miocene molluscan assemblages of Gram, Denmark, revealed differences in the presence and relative abundance of genera, functional congruence indicates that offshore benthic ecosystems of the southern North Sea Basin functioned similarly.</span></p>
Data from: Drivers of plant community (in)stability along a sea-inland gradient
<div> <div> <p><span>Global change pressures are highlighting the need to better understand the mechanisms driving the temporal stability of natural communities </span><span>under </span><span>different environmental conditions. There is </span><span>ample </span><span>evidence that species richness helps communities to withstand environmental fluctuations and stabilise over time</span><span>. However</span><span>, it is </span><span>still debated whether richness promotes </span><span>stability through the diversity of species functional traits, phylogenetic lineages, and ecological strategies in the community </span><span>or because of the likelihood of including stable species</span><span>. </span><span>Further, it is unclear</span><span> whether </span><span>the positive</span><span> effect </span><span>of diversity on stability is maintained in conditions</span><span> of strong environmental fluctuations (e.g. frequent disturbances and stress).</span><span> </span></p> </div> <div> <p><span>To address these questions, we analysed long-term monitoring data of 84 permanent plots in coastal dune plant communities distributed along a gradient of natural stress and disturbance, with communities closer to the sea subject to greater stress and more frequent disturbances. Specifically, we used structural equation models to disentangle the relative influence of the environmental gradient and the different diversity components (species richness, functional and phylogenetic diversity; SR, FD, and PD), as well as of the dominant ecological strategy (captured by species lifespan) on community stability, through their effect on two key stability mechanisms (population stability and species asynchrony).</span><span> </span></p> </div> </div> <div class="SCXW88064741 BCX0"> <div> <p><span>We found that the </span><span>sea-inland </span><span>environmental gradient was the main driver of stability mechanisms. Stress and disturbance decreased both population stability and species asynchrony, but also reduced species richness, which thus exerted a stabilising effect only on the communities in more favourable environmental conditions. </span><span> </span></p> </div> <div> <p><span>Surprisingly, </span><span>we did not find an effect of</span><span> FD and PD </span><span>on </span><span>community stability, neither directly nor via asynchrony. However, the dominance of perennial species mitigated the instability generated by stress and disturbance. Perennial species were on average more stable than annuals and displayed a wider range of species fluctuations, including compensatory dynamics among species (i.e. asynchrony). </span><span> </span></p> </div> <div class="ListContainerWrapper SCXW88064741 BCX0"> <p class="Paragraph SCXW88064741 BCX0"><strong><span>Synthesis:</span></strong><span> Overall, our results highlight the importance of accounting for the environmental context when examining mechanisms of community stability. Species richness remains a useful direct predictor of community stability. Species ecological strategies, like the acquisitive-conservative trade-off connected to lifespan, however, should also </span><span>be</span><span> routinely considered as drivers of both population stability and compensatory dynamics.</span></p> </div> </div>
