Predicting species abundance by implementing the ecological niche theory
<p>Species are not uniformly distributed across the landscape. For every species, there should be few favoured sites where abundance is high and many other sites of lower suitability where abundance is low. Consequently, local abundance could be thought of as a natural expression of species response to local conditions. The correlation between abundance and environmental suitability has been well documented, and a recent meta-analysis has suggested that this relationship could be a generality. Despite the importance and potential implication of the abundance-suitability relationship, its predictive power for meaningful extrapolations has been surprisingly poorly explored. In this study, we showed how a highly predictable trend can be extracted from the abundance-suitability relationship, accurately predicting the variation in species abundance at a high spatial resolution. We produced high-quality environmental suitability estimations for 50 endemic species to the Australian Wet Tropics. Environmental suitability derived from species distribution models was related to observed abundance estimated using data from 29 years of uninterrupted monitoring effort. We used the fitted relationship to accurately predict abundance at a fine scale across the species range. Our results showed that the abundance-suitability relationship was strong for endemic species in the Australian Wet Tropics. The predictive power of our models was high, explaining, on average, 55% of the deviance across taxa. Despite interspecific variation in the strength of the abundance-suitability relationship associated with potential intrinsic estimation biases, our approach provides a powerful tool for predicting abundance across the species range at a fine scale. The potential for robust abundance predictions from occurrence-based species distribution models shown in this study are numerous, and it could have a significant impact in enhancing species conservation and management decisions.</p>
Data for: Ecological and evolutionary origin of Costus flammulus (Costaceae): A new species from the montane cloud forests of the volcanic cordilleras in northern Costa Rica
<p><span><em>Costus</em> <em>flammulus</em> is a new herbaceous species endemic to montane cloud forests of </span><span>the volcanic cordilleras in northern Costa Rica. <em>Costus</em> <em>flammulus</em> has been mistaken </span><span>for <em>C</em>. <em>wilsonii</em>, but phylogenetic evidence demonstrates that it is closely related to the </span><span>widespread lowland species <em>C</em>. <em>pulverulentus</em>. Here, we used an integrated </span><span>framework of species concepts to evaluate whether <em>C</em>. <em>flammulus</em> and <em>C</em>. </span><span><em>pulverulentus</em> are distinct species. First, we re-evaluate prior phylogenetic analyses to </span><span>assess whether <em>C</em>. <em>flammulus</em> bifurcated from or budded off from within <em>C</em>. </span><span><em>pulverulentus</em> and whether <em>C</em>. <em>flammulus</em> is monophyletic. We then compare </span><span>phenotypic traits to determine which diagnostic vegetative and inflorescence traits can </span><span>be used to identify species in herbarium specimens and examine whether floral traits </span><span>may confer floral isolation. We compare pollinator assemblages to examine whether </span><span>pollinator specificity may contribute to reproductive isolation. Finally, we model species </span><span>distributions and climatic niche overlap to assess ecogeographic isolation. We found </span><span>that <em>C</em>. <em>flammulus</em> is a monophyletic species phenotypically, ecologically, and </span><span>geographically distinct from <em>C</em>. <em>pulverulentus</em> and may have speciated as a peripheral </span><span>isolate at the high elevation range edge of <em>C</em>. <em>pulverulentus</em>. Several lines of </span><span>evidence, such as <em>C</em>. <em>pulverulentus</em> paraphyly, range size asymmetry, and C. </span><span>flammulus' nested distribution and vegetative traits, suggest that <em>C</em>. <em>flammulus</em> </span><span>budded off from a <em>C</em>. <em>pulverulentus</em>‐like progenitor species, evolving to tolerate a </span><span>colder and more seasonal montane environment.</span></p>

Impacts of ecological restoration on the genetic diversity of plant species: A global meta-analysis
<p>1. In contrast to the depth of knowledge available for the enhancement of plant species diversity and ecosystem services through ecological restoration, our understanding of how ecological restoration impacts genetic diversity (GD) of plant species has not yet been synthesized.</p> <p>2. We performed a global meta-analysis to examine whether ecological restoration improved GD of plant species in restored populations. First, we compared the GD of restored populations with reference or degraded populations. Second, we explored whether the influence of ecological restoration on plant GD varies between species with different characteristics (life form and threat status), between different restoration strategies (active/passive, seeding/planting, mixture/non-mixture) or between different restoration times (<50 and ≥50 years; with an average of 29.3 years).</p> <p>3. The GD of restored populations was significantly lower (HE, 1.06%; PPB, 5.10%, and SWI, 4.95%) than in reference populations but was comparable to degraded populations. The inbreeding coefficient (FIS, the proportion by which the heterozygosity of an individual is reduced by inbreeding) was consistently comparable between restored populations and reference or degraded populations.</p> <p>4. Woody species but not herbs had significantly lower GD in restored populations than in reference populations. Forest but not grassland ecosystem had significantly lower GD in restored populations than in reference populations. Passive but not active restoration, seeding rather than planting, and mixing materials from different sources rather than using a single source, all significantly increased the GD of restored populations. When the restoration time was ≥50 years, in contrast to <50 years, GD was comparable between the restored and reference populations.</p> <p>5. Synthesis and applications. In general, ecological restoration did not significantly improve the GD of plant species compared to reference or degraded populations. This might be due in part to the relatively short restoration time. Using passive restoration, seeding, and mixed sources could significantly increase the GD of restored populations. We emphasize that GD should not be treated as a minor cobenefit of ecological restoration for other purposes and that the recovery of GD should be listed as a vital goal in future ecological restoration with plant species.</p>

As a result, Chile encompasses diverse environments, including the Mediterranean-type ecosystem, a global biodiversity hotspot. These environments are currently threatened by anthropogenic land use change impacting the integrity of local biomes and associated species. This area is the most intensively sampled of the country with high endemicity of native bee species. Characterising habitat requirements of bees is a pressing priority to safeguard these insects and the ecosystem services they provide. We investigated broad-scale patterns of bee (Hymenoptera: Apoidea: Anthophila) diversity using newly accessible expert-validated datasets comprising digitized specimen records from Chilean and US collections, and novel expert-validated type specimen data for the bees of Chile. We used a generalised dissimilarity modelling (GDM) approach to explore both compositional and phylogenetic β-diversity patterns across latitudinal, altitudinal, climate and habitat gradients in well-sampled bee assemblages in Central Chile. Using the GDM measures of increasing compositional and environmental dissimilarity we categorised and compared the most important drivers of these patterns and used them to classify 'wild bee ecoregions' (WBE) representing unique assemblages. Turnover of bee assemblages was explained primarily by latitudinal variation (proxy for climate) from south to north in Chile. However, temperature variations, precipitation and the presence of bare soil also significantly explained turnover in bee assemblages. In comparison, we observed less turnover in phylogenetic biodiversity corresponding to spatial gradients. We identified six de novo ecoregions (WBE), all with distinct taxa, endemic lineages, and representative species. The WBE represent distinct spatial classifications but have similarities to existing biogeographical classifications, ecosystems and bioclimatic zones. This approach establishes the baseline needed to prioritise bee species conservation efforts across this global biodiversity hotspot. We discuss the novelty of this classification considering previous biogeographical characterisations and their relevance in assessing conservation priorities for bee conservation. We argue that Chile's WBE highlight areas in need of funding for bee species surveys and description, distribution mapping and strengthening of conservation policies.</p> <p>Usage notes</p> <p>The dataset contains species occurrence data of chilean bees aggregated to a 5 x 5 km grid shapefile.

Species phylogeny, ecology and root traits as predictors of root exudate composition
<p>In this study, a total of 65 neophytes (alien species introduced after 1500 A.D.), belonging to 51 genera and 25 families, occurring in the Czech Republic, were used. The species set represented plant families only from eudicots with Asteraceae, Brassicaceae Amaranthaceae, Polygonaceae and Fabaceae as the major families having 4 or more species. We measured different root morphological and biochemical traits (including exudate profiles) of these plant species grown in a controlled system. </p>
