Dataset from: Functional traits explain both seedling and adult plant spatial patterns in gypsum annual species
<p><span>1. </span><span>Ecological processes such as seed dispersal or plant–plant interactions and environmental constraints such as climate or soil heterogeneity are known to influence establishment, and thus the spatial patterns of plant communities and populations. In this study, we hypothesized that key functional traits such as the specific leaf area (SLA), reproductive ratio (reproductive/vegetative biomass), seed mass, and maximum plant height would influence the spatial patterns of individual species in annual, gypsophilous plant communities, and that these effects would be modulated by both the soil surface structure (biocrust) and climate (precipitation) conditions. </span></p> <p><span>2. </span><span>We mapped the spatial patterns of all plants found in six 1 </span><span>x</span><span> 1 m plots (more than 1000 individuals per plot) in both the seedling (autumn) and adult stages (spring) under two biocrust experimental conditions (intact vs disturbed biocrust) during two consecutive years which were contrasted in term of precipitation (dry year and wet year). To assess the spatial patterns of seedlings and adults, we fitted four different spatial point pattern models (i.e., Poisson, inhomogeneous Poisson, Poisson cluster, and inhomogeneous Poisson cluster processes) to each of the 242 populations of the 27 most abundant species that had more than 15 individuals per plot.</span></p> <p><span>3. </span><span>Most seedling populations exhibited clustered spatial patterns that persisted in the adult stage, which suggests that short-distance dispersal is an adaptive trait for soil specialists such as gypsophilous plants. One-third of the populations fitted an inhomogeneous model best, but the physical structure of the biocrust was not related to them. More importantly, we found a connection between the functional strategies of species and the spatial distribution of plants. In particular, during the dry year, irrespective of the biocrust conditions, species with a high SLA and high Rep/Veg mainly exhibited clustered spatial patterns, whereas low SLA and low Rep/Veg were associated with random distributions. Species with heavy and light seed masses had random and clustered patterns, respectively. In both the dry and wet years, species with lower maximum heights had clustered patterns, whereas taller species exhibited random patterns. In addition, species with heavier seeds and greater maximum heights had the largest cluster sizes.</span></p> <p><span>4. </span><span>Our results confirm that the spatial patterns of seedlings and adult plants are significantly determined by the functional strategy of each species.</span></p>
Effects of food plants on life-history traits of the newly invasive fall armyworm Spodoptera frugiperda
<p><strong>Background:</strong>The fall armyworm (FAW) <em>Spodoptera frugiperda</em> (J. E. Smith) (Lepidoptera; Noctuidae) has invaded Jiangxi Province, Southeast China for the past three years. Although the FAW displays a wide host range, its main host plants in Jiangxi Province is field corn. Understanding the population dynamics of the FAW on different host plants is critical for developing an appropriate control strategy.</p> <p><strong>Objectives: </strong>This study investigated the effects of food plants (corn, peanut, soybean and sugarcane) on life-history traits of FAW and tested the leaf contents of the total flavonoids, reducing sugars, sucrose and C/N ratio of these host plants.</p> <p><strong>Results: </strong>We found that the FAW fed on corn leaves exhibited significantly shorter larval and pupal development times, larger body weight, higher growth rate, lower weight loss, smaller sexual size dimorphism, shorter preoviposition period and higher fecundity than those fed on peanut, soybean and sugarcane leaves. The FAW showed a protogyny phenomenon because the pupal development stage was significantly longer in males than females. Food plants changed the relationships between larval development time and pupal weight and between fecundity and longevity. The corn leaves showed significantly higher contents of reducing sugars and sucrose, lower content of the total flavonoids and a moderate C/N ratio compared with the other leaves, suggesting that the corn leaf tissues are more nutritious.</p> <p><strong>Conclusions: </strong>Our results provide the most comprehensive information about the life-history traits of this newly invasive pest. These findings may help us understand why the FAW mainly infests corn plants and may be critical for the development of strategies to predict infestation levels.</p>
Data from: Trait-based effects of plant invasion on floral resources, hoverflies and bees
<p>1. Plant invasions can lead to homogeneous communities with decreased functional diversity. However, invasive plants, with various morphological and phenological traits, may drive pollinator communities in a less predictable, more complex way. They can promote pollinators compatible with their floral traits while leaving others without foraging resources.</p> <p>2. Our observational study on 10 invasive herbaceous species applied a trait-based approach to investigate plant invasion-driven changes in floral resources, hoverfly, and bee communities. We sampled invaded and non-invaded (control) sites before and during the flowering of the invasive plants. We analysed the differences in floral traits between invasive and native plants, functional diversity, and trait distributions of flower and pollinator communities between the invaded and control sites.</p> <p>3. Five invasive plant species differed from natives in floral traits. Plant invasion caused species-specific changes in functional diversity and trait distributions of communities. For instance, invaded sites had a decreased functional diversity of hoverflies before flowering of invasive species, and larger hoverflies during flowering of invasive species compared with control sites. Smaller bees were associated with invasive plants with shallow flowers, while larger and long-tongued bees were associated with two invasive species with restricted floral access.</p> <p>4. Similar to previous studies, pollinator traits showed mixed or neutral responses to plant invasion. This is probably due to the high integration capability of invasive plants into plant-pollinator systems, or limitations in sampling, trait resolution, and unrevealed environmental factors. We provide recommendations for future studies to better understand the trait-based community composition of flowering plants and pollinators.</p>

Trade-off between dispersal traits in a heterocarpic plant across its invasion route
<p>Dispersal ability can vary across plant species or populations, such as among core compared to leading populations of invasive plants. However, in heterocarpic plants, which produce propagules with varying dispersal abilities, dispersal potential can also increase via investment in the proportion of dispersing morphs (termed dispersal rate). Nevertheless, very little is known about the interplay between investment in dispersing structures vs. dispersal rate or how each is affected by varying environmental pressures.</p> <p><strong><em>Methods</em></strong></p> <p>This study examined the interplay between investment in dispersing structures and dispersal rate across the invasion route of the heterocarpic plant <em>Heterotheca subaxillaris</em>. <em>H. subaxillaris</em>'s capitula were collected from eight populations along its invasion route in the Eastern Mediterranean coastal plain. The dispersal ability of dispersing pappus-bearing achenes was measured as the ratio between their pappus width and biomass. The dispersal rate was calculated as the ratio between the number of dispersing achenes and total achenes per capitulum. </p> <p><em><strong>Key Results </strong></em></p> <p>The dispersal ability of the dispersing achenes and dispersal rate were found to be negatively correlated across <em>H. subaxillaris</em>' populations, with a greater investment in pappus length in populations at the leading edge of the invasion compared to a greater number of dispersing achenes in core populations.</p> <p><em><strong>Conclusions</strong></em> </p> <p>Our results suggest a trade-off might exist between dispersal ability and dispersal rate, which could change along the invasion route of heterocarpic plants such as <em>H. subaxillaris</em> and contribute to their invasive success. This study highlights the importance of examining both dispersal traits when studying the dispersal potential of heterocarpic species. </p>

The relationships of plant species occupancy to niches and traits vary with spatial scale
<p>Aim: Support for different underlying mechanisms of species occupancy is inconsistent, yet this could be related to spatial scale. Since abiotic filtering typically acts at broader scales than biotic interactions, we hypothesise that occupancy could be more driven by species' abiotic niche (i.e., tolerance and preference of abiotic conditions) at broad scales, whereas species' traits affecting competitive ability could be more important at fine scales. Here we test these hypotheses by assessing relationships of occupancy to niche and trait metrics across spatial scales.</p> <p>Location: Four study areas located north of Arctic Circle.</p> <p>Taxon: Vascular plants.</p> <p>Methods: We derived occupancy for 106 species at four spatial scales (Micro-scale with plot size of 0.04 m <sup>2</sup> and extent of 2 km, Local-scale with plot size of 4 m <sup>2</sup> and extent of 40 km, Regional-scale with plot size of 4 ha and extent of 800 km, and Polar-scale with plot size of 4 km <sup>2</sup> and extent of 5200 km). We then assessed using generalized additive models whether the relationships between occupancy and species' niche breadth, niche marginality, intraspecific trait variability (ITV) and trait distinctiveness vary across the scales.</p> <p>Results: At the finer scales, ITV (especially of specific leaf area) had the highest contribution with positive relationship in explaining occupancy. At the broader scales, occupancy was better explained by niche metrics. Especially at the broadest scale, the occupancy had a positive relationship with species' climatic tolerance.</p> <p>Main conclusions: Abiotic filtering, especially related to macro-climate, drives species occupancy at broader spatial scales while biotic interactions are relatively more important at local scales. This scale-dependency of factors behind species occupancy should be accounted for when, for example, planning conservation of rare species, forecasting invasions, or anticipating the effects of changing climate on biota at local versus global scales.</p>
Genes associated with plant growth-promoting traits (PGPTs) in acidobacteriota MAGs
<p>The prevalence and abundance of Acidobacteriota raise concerns about their ecological function and metabolic activity in the environment. Studies have reported the potential of some members of Acidobacteriota to interact with plants and play a significant role in biogeochemical cycles. However, their role in this context has not been extensively studied. Here, we performed a comprehensive genomic analysis of 758 metagenome-assembled genomes (MAGs) of Acidobacteriota, revealing a high frequency of plant growth-promoting traits (PGPTs) genes.</p>
