Regional and local environment drive biogeographic patterns in intertidal microorganisms
<p><span>Aim:</span><span> Understanding large-scale spatial distribution patterns is not only a central goal of ecology but is also essential for conservation planning. Nevertheless, the biogeographical patterns of diversity and composition remain unclear for microorganisms and the role of various factors in structuring their assemblages is still poorly known. Here, we tested whether the diversity and community structure of ciliates are driven by both local environmental and regional dispersal-related processes.</span></p> <p><span>Location:</span><span> Coasts of China.</span></p> <p><span>Taxon:</span><span> Benthic ciliates.</span></p> <p><span>Results:</span><span> We found that local environmental factors including BI, salinity and MPS were more important in shaping ciliate alpha diversity than latitude. However, the Shannon alpha diversity index decreased with latitude, perhaps due to anthropogenic disturbances. DistLM analysis emphasized regional processes in shaping community structure. Both NMDS and PERMANOVA supported a clear separation among the three clusters matching with the ecoregional delineations suggested for macroorganisms. We also note that community trait composition was partially explained by a local factor, i.e. the maximum spring tide range of beaches.</span></p> <p><span>Main conclusions:</span><span> Ciliate communities were driven by both local environmental and regional factors. We suggest that these biogeographic patterns may have stemmed from large-scale environmental filtering related to the outflow of Yangtze River, rather than from dispersal limitation or historical events. The current study provides a new understanding of the biogeographic patterns and underlying mechanisms of marine microorganisms, thus helping improve their management and conservation in the face of future global change.</span></p>
Distribution. Endemic to C & SE Sulawesi; known from various lowland and more mountainous regions, including Mt Rorekatimbo, Mt Gandangdewata, Mt Balease, and Mt Nokilalaki. Together with the Elongated White-toothed Shrew (C. elongata) this is the only wild shrew occurring on the SE peninsula, but lack of adequate sampling in most pristine areas of S Sulawesi hinders precise biogeographical inferences. in Soricidae

FIGURE 5 in Contributions of biogeographical functions to species accumulation may change over time in refugial regions
FIGURE 5 Ancestral area estimation of interspecific MOTUs (A–R) and lineages of Theodoxus obtained from BioGeoBEARS. Clades (C) and subclades (SC) are demarcated by dashed lines between MOTUs. Pie charts represent the relative likelihood of the lineage occurring within Anatolia (dark blue), occurring both within and outside of Anatolia (light blue) and just outside of Anatolia (grey). Small circles with the same colour scheme as the pie charts indicate the most likely state. The bars above the MOTUs represent their current distribution. Small squares at nodes indicate significant support of divergence events found with BEAST and other phylogenetic analyses (see Figures S2.1 and S2.2), as explained through the key. Cradle, museum and tap icons represent the relative contributions of functions (cradles, museums and sinks) at different points across the topology for Anatolian diversity. The grey shading indicates the period of pronounced glacial cycles (last 900 kyr) [Colour figure can be viewed at wileyonlinelibrary.com]

FIGURE 1 Operational criteria based on ancestral distributions used to identify and distinguish between the cradle, museum and sink functions. The functions are identifiable by: (a) the cradle function, having an in situ distributed ancestor and descendant with either strict in situ distribution or both in‐ and ex situ distribution, (b) the museum function, having an ancestor with both in‐ and ex situ distribution followed by a descendant with only in situ distribution and (c) the sink function, having an ex situ distributed ancestor with either a strict in situ distribution or with both in‐ and ex situ distribution [Colour figure can be viewed at wileyonlinelibrary.com]
