Indicative distribution map for Ecosystem Functional Group M3.1 Continental and island slopes
<p>This archive contains indicative distribution maps and profiles for <strong>M3.1 Continental and island slopes</strong>, a ecosystem functional group (EFG, level 3) of the <a href="https://global-ecosystems.org/">IUCN Global Ecosystem Typology</a> (v2.0). Please refer to Keith <em>et al.</em> (2020) for details.</p> <p>The descriptive profiles provide brief summaries of key ecological traits and processes, maps are indicative of global distribution patterns, and are not intended to represent fine-scale patterns. The maps show areas of the world containing major (value of 1, coloured red) or minor occurrences (value of 2, coloured yellow) of each ecosystem functional group. Minor occurrences are areas where an ecosystem functional group is scattered in patches within matrices of other ecosystem functional groups or where they occur in substantial areas, but only within a segment of a larger region. Given bounds of resolution and accuracy of source data, the maps should be used to query which EFG are likely to occur within areas, rather than which occur at particular point locations. Detailed methods and references for the maps are included in the profile (xml format).</p>

Fisher's α, an alternative measure of local diversity (not shown), is lowest at the Malaysian sites (α = 7–13) and highest at a montane site in Northwestern Thailand (α = 30), whereas the Vietnam sample and other Thai sites score intermediately (α = 11–21).

Data from: Lineage-specific trait variations and plasticity of obligate parthenogenetic animals following the expansion of distribution range to a continental archipelago.
<p><span>Two asexual lineages, JPN1 and JPN2, of panarctic <em>Daphnia pulex</em> expanded the distribution range to Japan from North America, independent of each other. According to the mutation rates within these lineages, JPN1 lineage colonized Japan earlier than JPN2 lineage. Moreover, the ratio of nonsynonymous to synonymous mutation rates (dN/dS) was lower in JPN1 than in JPN2 lineage.</span></p> <p><span>Accordingly, it is hypothesized that variations of phenotypic traits differ between these two lineages. In addition, since they are obligate parthenogenetic animals, the lineage occupying a larger distribution range should have a larger phenotypic plasticity. To test these hypotheses, we experimentally examined the phenotypic variations of fitness-related traits, including digestive, life history and morphological traits, among several genotypes of these lineages.</span></p> <p><span>We found that within-lineage variations of most traits were smaller in JPN1 than in JPN2. In addition, the overall phenotypic variations were also smaller within the JPN1 lineage than within the JPN2 lineage. These results support the idea that the JPN1 lineage has been more efficiently subjected to negative selection, as expected from the lower dN/dS ratio.</span></p> <p><span>However, the magnitude of the phenotypic plasticity to changing food levels was at the same level for both the JPN1 and JPN2 lineages, while variations found in the phenotypic plasticity were smaller in the JPN1 lineage. The difference in the variations of the phenotypic traits and plasticity between the two lineages suggests that these two lineages have evolved under somewhat different environmental conditions and that genotypes of the JPN2 lineage may have exploited niches that differed somewhat from that of the JPN1 genotypes.</span></p>
Data from: Evolutionarily labile dispersal behavior and discontinuous habitats enhance population differentiation in island vs continentally distributed swallows
<p class="MsoNormal"><span>The causes of population divergence in vagile groups remain a paradox in evolutionary biology: dispersive species should be able to colonize new areas, a prerequisite for allopatric speciation, but dispersal also facilitates gene flow, which erodes population differentiation. Strong dispersal ability has been suggested to enhance divergence in patchy habitats and inhibit divergence in continuous landscapes, but empirical support for this hypothesis is lacking. Here we compared patterns of population divergence in a dispersive clade of swallows distributed across both patchy and continuous habitats. The Pacific Swallow (</span><em>Hirundo tahitica</em><span>) has an insular distribution throughout Southeast Asia and the Pacific, while its sister species, the Welcome Swallow (</span><em>H. neoxena</em><span>), has a continental distribution in Australia. We used whole-genome data to demonstrate strong genetic structure and limited introgression among insular populations, but not among continental populations. Demographic models show that historic changes in habitat connectivity have contributed to population structure within the cl</span>ade. Swallows appear to exhibit evolutionarily labile dispersal behavior in which they reduce dispersal propensity after island colonization despite retaining strong flight ability. Our data support the hypothesis that fragmented habitats enhance population differentiation in vagile groups, and suggest that labile dispersal behavior is a key mechanism underlying this pattern.</p>

Data from: From ratites to rats: the size of fleshy fruits shapes species' distributions and continental rainforest assembly
Seed dispersal is a key process in plant spatial dynamics. However, consistently applicable generalisations about dispersal across scales are mostly absent because of the constraints on measuring propagule dispersal distances for many species. Here, we focus on fleshy-fruited taxa, specifically taxa with large fleshy fruits and their dispersers across an entire continental rainforest biome. We compare species-level results of whole-chloroplast DNA analyses in sister taxa with large and small fruits, to regional plot-based samples (310 plots), and whole of continent patterns for the distribution of woody species with either large (>30mm) or smaller fleshy fruits (1093 taxa). The pairwise genomic comparison found higher genetic distances between populations and between regions in the large-fruited species (Endiandra globosa), but higher overall diversity within the small-fruited species (Endiandra discolor). Floristic comparisons among plots confirmed lower numbers of large-fruited species in areas where more extreme rainforest contraction occurred, and re-colonisation by small-fruited species readily dispersed by the available fauna. Species distribution patterns showed that larger-fruited species had smaller geographic ranges than smaller-fruited species and locations with stable refugia (and high endemism) aligned with concentrations of large fleshy-fruited taxa, making them a potentially valuable conservation-planning indicator.
