Spatial and local environmental factors outperform geo-climatic gradients in structuring taxonomically- and traits-based β‐diversity of benthic algae
<p><b>Aim</b>: Understanding the variation in biodiversity and its underlying drivers and mechanisms is a core task in biogeography and ecology. In this study, we examined: i) the relative contributions of species replacement (i.e. turnover) and richness difference (i.e. nestedness) to taxonomically- and traits-based β-diversity of stream benthic algae; ii) whether these two facets of β-diversity are correlated with each other; and iii) the relative contributions of local environmental (e.g. water chemistry, flow velocity, habitat quality), geo-climatic (e.g. land use types, elevation, precipitation), and spatial factors (e.g. using principal coordinates of neighborhood matrices) to the two facets of β-diversity and their components (i.e. total β-diversity, turnover, and nestedness).</p> <p><b>Location</b>: Hun-Tai River Basin, northeastern China</p> <p><b>Taxon</b>: Stream benthic algae</p> <p><b>Methods</b>: A total of 157 sites were sampled. Mantel tests were used to examine the complementarities between the two facets of β-diversity and their components. Distance-based redundancy analysis and variation partitioning were utilized to investigate the relative contributions of local environmental, geo-climatic, and spatial factors to each facet of β-diversity and their components.</p> <p><b>Results</b>: Weak correlations between taxonomically- and traits-based β‐diversity and their components were detected, which indicated complementarity of ecological information. Taxonomically-based total β‐diversity was largely driven by turnover, whereas traits-based total β-diversity was more driven by nestedness. Variation partitioning results indicated that local environmental and spatial factors contributed more than geo-climatic variables to the total explained variation in taxonomically- and traits-based β‐diversity.</p> <p><b>Main conclusions</b>: Our findings highlighted the importance of the different facets of β‐diversity and their decomposition for understanding diversity patterns of benthic algae relative to abiotic factors. A high level of traits-based convergence among benthic algae communities, despite high taxonomic divergence, demonstrated turnover of species with similar biological traits across our study region. Our study provides a traits-based insight into stream benthic algae communities, which was less documented by previous freshwater studies that focused on regions undergoing recovery following human disturbances.</p>
Exploring phenotypic diversity of pigmented traits and iris features in Pakistani population
<p><span>Phenotypic variations of eye color, skin color, and iris surface features have been well-explored in certain populations. However, there has been comparatively little research on variations in these features in Pakistani population. The aim of this study is to</span> discover phenotypic diversity and correlations of pigmented traits and iris surface features in Punjab and Khyber-Pakhtunkhwa (KPK)<b> </b>province of Pakistan<b>.</b> Digital images of eyes and skin were examined by investigators to determine color using Fitzpatrick Phototype Scale. Similarly, iris patterns were characterized by Edward iris feature software and association studies were conducted through SPSS program. Intermediate eye color was frequent in KPK (44%) while brown was higher in Punjab (47%). <span>Contrarily</span>, light to medium brown skin color was recurring (55%) in Punjab whereas lighter skin color prevailed in KPK (69%). Furthermore, Fuchs' crypts were significantly correlated with contraction furrows in both populations. Likewise, crypts were significantly associated with Wolfflin nodules and furrows were significantly related to conjunctival melanosis and pigment spots in KPK sample set. Based on unique iris patterns, these phenotypic traits would be helpful for individuals' discrimination in the population<b>. </b>In future, there is need to explore genetic associations and functional differences of these traits.</p>
The data table of eleven invasive species in Hungary and Romania: Invasive species' cover, invasive species' traits, basic characteristics, trait composition, functional diversity indices and soil parameters of recipient plant communities
<p>We studied 11 widespread herbaceous invasive alien species of East-Central Europe and their 16 impact metrics (resident plant communities' ecological characteristics, trait composition, functional diversity, and soil parameters) by sampling invaded and similar, uninvaded sites (space-for-time substitution method). Our aim was to (1) investigate the detailed ecological impacts of invasive plants on native plant communities; (2) explore the type of cover-impact relationships across impact metrics and their consistency across species; (3) study whether the cover-impact relationship depends on functional traits of invasive species. We present the data table with the 11 invasive species: the status of the sites (invaded, uninvaded), the cover of invasive species at plot level, the invasive species traits (lifespan, height, SLA, seed mass, clonal spread, flowering duration), community characteristics (species richness and diversity, native vegetation cover and bare ground cover at plot level), trait composition of native plant communities (native vegetation height, CWM height, CWM SLA, CWM seed mass, CWM clonal spread), functional diversity (functional richness, functional evenness, functional divergence, functional distance, RaoQ) and soil properties (N, P, organic C, pH).</p>
Genetic diversity varies with species traits and latitude in predatory soil arthropods (Myriapoda: Chilopoda)
<p><strong>Aim</strong></p> <p>To investigate the drivers of intra-specific genetic diversity in centipedes, a group of ancient predatory soil arthropods.</p> <p><strong>Location</strong></p> <p>Asia, Australasia and Europe</p> <p><strong>Time period</strong></p> <p>Present</p> <p><strong>Major taxa studied</strong></p> <p>Centipedes (Class: Chilopoda)</p> <p><strong>Methods</strong></p> <p>We assembled a database of 1245 mitochondrial cytochrome c oxidase subunit I sequences representing 128 centipede species from all five orders of Chilopoda. This sequence dataset was used to estimate genetic diversity for centipede species and compare its distribution with estimates from other arthropod groups. We studied the variation in centipede genetic diversity with species traits and biogeography using a beta regression framework, controlling for the effect of shared evolutionary history within a family.</p> <p><strong>Results</strong></p> <p>A wide variation in genetic diversity across centipede species (0 to 0.1713) falls towards the higher end of values among arthropods. Overall, 27.57% of the variation in mitochondrial COI genetic diversity in centipedes was explained by a combination of predictors related to life history and biogeography. Genetic diversity decreased with body size and latitudinal position of sampled localities, was greater in species showing maternal care and increased with geographic distance among conspecifics.</p> <p><strong>Main conclusions</strong></p> <p>Centipedes fall towards the higher end of genetic diversity among arthropods, which may be related to their long evolutionary history and low dispersal ability. In centipedes, the negative association of body size with genetic diversity may be mediated by its influence on local abundance or the influence of ecological strategy on long-term population history. Species with maternal care had higher genetic diversity, which goes against expectations and needs further scrutiny. Hemispheric differences in genetic diversity can be due to historic climatic stability and lower seasonality in the southern hemisphere. Overall, we find that despite the differences in mean genetic diversity among animals, similar processes related to life history strategy and biogeography are associated with the variation within them.</p>
Data from: Host phylogeny and functional traits differentiate gut microbiomes in a diverse natural community of small mammals
<p>Differences in the bacteria inhabiting mammalian gut microbiomes tend to reflect the phylogenetic relatedness of their hosts, a pattern dubbed phylosymbiosis. Although most research on this pattern has compared the gut microbiomes of host species across biomes, understanding the evolutionary and ecological processes that generate phylosymbiosis requires comparisons across phylogenetic scales and under similar ecological conditions. We analyzed the gut microbiomes of 14 sympatric small-mammal species in a semi-arid African savanna, hypothesizing that there would be a strong phylosymbiosis pattern associated with the different body sizes and diets of the mammalian lineages present. Consistent with phylosymbiosis, microbiome dissimilarity increased with phylogenetic distance among hosts, ranging from congeneric sets of mice and hares that did not differ significantly in microbiome composition to species from different taxonomic orders that had almost no gut bacteria in common. While phylosymbiosis was detected among just the 11 species of rodents, it was substantially weaker than comparisons involving all 14 species together. In contrast, microbiome diversity and composition were generally more strongly correlated with body size, dietary breadth, and dietary overlap in comparisons restricted to rodents than in those including all lineages. The starkest divides in microbiome composition thus reflected the broad evolutionary divergence of hosts, regardless of body size or dietary composition, while subtler microbiome differences reflected variation in ecologically important traits between closely related hosts. Strong phylosymbiotic patterns arose deep in the phylogeny, and ecological filters that promote functional differentiation of cooccurring host species may disrupt or obscure this pattern near the tips.</p>
Data for: Sampling local ant diversities and the importance of trait analyses
<p>Ants are an incredibly diverse and ubiquitous group of invertebrates in most terrestrial ecosystems. Although extensively sampled, the majority of ant inventories do not evaluate the effect of different sampling techniques in capturing non-traditional metrics of diversity. We aimed to quantify TD (taxonomic) and FD (functional) diversities for a local ant assemblage by integrating metrics and evaluating complementarity of pitfall traps and Winkler extractors for the leaf-litter vs. epigaeic ant faunas and to determine the effect of sampling techniques on functional composition (community-weighted means of 11 morphological traits, see <strong>Table S1</strong> in the Excel file and <strong>Trait_base_data.csv</strong> in this dataset) and functional diversity (multi-trait morphospace measured with three different metrics, see <strong>Table S2</strong> in Excel file). We sampled the local community (<strong>Table S3</strong> and <strong>Table S4 </strong>in the Excel file) in an Atlantic Forest fragment using week-long pitfall traps and 1m<sup>2</sup> leaf litter samples submitted to Winkler extractors and quantified the contribution on the technique (refer to <strong>Community_data.csv</strong> in this dataset) to uniquely capture the ant morphospace by applying a new index (PWindex). Although ant TD overlapped, FD was significantly affected by the sampling technique. By controlling for TD effects, the community collected by each technique was differentially structured. Higher TD did not translate into wider morphospace for Winklers. Pitfalls recovered more functionally overdispersed assemblages. Pitfalls and Winklers overlapped in the sampling of the overall community, but each sampling method contributed with a unique spectrum to the ant morphospace. Our results suggest the importance of incorporating FD metrics in local ant inventories and the importance of sampling techniques when measuring the magnitude of FD and community structure. Our PWindex further illuminates sampling effects for ant assemblages.</p>
Eutrophication decreases ecological resilience by reducing species diversity and altering functional traits of submerged macrophytes
<p><span>Positive feedback is key to producing alternative stable states and largely determines ecological resilience in response to external perturbations. Understanding the positive feedback mechanisms in macrophyte-dominated lakes is crucial for resilience-based management and restoration. Based on the field investigation of submerged macrophyte communities in 35 lakes in China, we found that morphological complexity (<em>MC</em>) and morphological plasticity (<em>MP</em>) are correlated with the stoichiometric homeostasis of phosphorus (<em>H<sub>P</sub></em>) and are related to ecosystem structure, functioning, and stability. We also found that the positive feedback strength of lakes dominated by macrophytes is biomass- and diversity-dependent. Eutrophication can decrease the community biomass by decreasing community<em> MC, MP,</em> and <em>H<sub>P</sub></em> and the species diversity through low-light availability, ultimately decreasing the positive feedback strength and resilience of clear-water states. We argue that functional traits and species diversity should be considered to build more resilient ecosystems in future changing environment scenarios.</span></p>
Sequencing data for: Chronosequence of invasion reveals minimal losses of population genomic diversity, niche expansion, and trait divergence in the polyploid, leafy spurge
<p>Rapid evolution may play an important role in the range expansion of invasive species and modify forecasts of invasion, which are the backbone of land management strategies. However, losses of genetic variation associated with colonization bottlenecks may constrain trait and niche divergence at leading range edges, thereby impacting management decisions that anticipate future range expansion. The spatial and temporal scales over which adaptation contributes to invasion dynamics remain unresolved. We leveraged detailed records of the ~130-year invasion history of the invasive polyploid plant, leafy spurge (<em>Euphorbia</em> <em>virgata</em>), across ~500km in Minnesota, U.S.A. We examined the consequences of range expansion for population genomic diversity, niche breadth, and the evolution of germination behavior. Using genotyping-by-sequencing, we found some population structure in the range core, where introduction occurred, but panmixia among all other populations. Range expansion was accompanied by only modest losses in sequence diversity, with small, isolated populations at the leading edge harboring similar levels of diversity to those in the range core. The climatic niche expanded during most of the range expansion, and the niche of the range core was largely non-overlapping with the invasion front. Ecological niche models indicated that mean temperature of the warmest quarter was the strongest determinant of habitat suitability and that populations at the leading edge had the lowest habitat suitability. Guided by these findings, we tested for rapid evolution in germination behavior over the time course of range expansion using a common garden experiment and temperature manipulations. Germination behavior diverged from early to late phases of the invasion, with populations from later phases having higher dormancy at lower temperatures. Our results suggest that trait evolution may have contributed to niche expansion during invasion and that distribution models, which inform future management planning, may underestimate invasion potential without accounting for evolution.</p>
Artificial light at night (ALAN) decreases plant diversity and performance in experimental grassland communities – Data on species biomass and traits
<p>Artificial light at night (ALAN) affects many areas of the world and is increasing globally. To date, there has been limited and inconsistent evidence regarding the consequences of ALAN on plant communities as well as the fitness of their constituent species. ALAN could be beneficial for plants as they need light as an energy source, but they also need darkness for regeneration and growth. We created model communities composed of 16 plant species sown, exposed to a gradient of ALAN ranging from 'moonlight only' to conditions like situations typically found directly underneath a streetlamp. We measured plant community composition and its production (biomass), as well as functional traits of three plant species from different functional groups (grasses, herbs, legumes) in two separate harvests. We found that biomass was reduced by 33% in the highest ALAN treatment compared to the control, Shannon diversity decreased by 43% and Evenness by 34% in the first harvest. Some species failed to establish in the second harvest. Specific leaf area, leaf dry matter content and leaf hairiness responded to ALAN. These responses suggest that plant communities will be sensitive to increasing ALAN, and they flag a need for plant conservation activities that consider impending ALAN scenarios.</p>
