Figure 2 in Phylogenetic analysis of the Niphargus orcinus species- aggregate (Crustacea: Amphipoda: Niphargidae) with description of new taxa
Figure 2. Distribution of characters ''body shape'' (character 2, CI51, RI51; left) and ''body size'' (character 1, CI50.28, RI50.37; right). Note that the body shape is plesiomorphic in most of the ''Orniphargus'' taxa, and large body size is a highly convergent (possibly troglomorphic) character.
Figure 1. A in Phylogenetic analysis of the Niphargus orcinus species- aggregate (Crustacea: Amphipoda: Niphargidae) with description of new taxa
Figure 1. A strict consensus tree of 34 most parsimonious trees (length5472; CI50.26, RI50.60). Values of Bremer support index (decay index) are indicated below branches. Taxa traditionally assigned to the ''Orniphargus'' species aggregate, as well as clades for which character analysis was performed, are encircled in boxes. Note 1: Despite of its position on the cladogram N. pectinicauda has never been considered as an ''Orniphargus'' taxon. Note 2: Taxa are named according to their lowest rank. For full names, see Tables I and II.
Figure 5 in Phylogenetic analysis of the Niphargus orcinus species- aggregate (Crustacea: Amphipoda: Niphargidae) with description of new taxa
Figure 5. Distribution of characters ''type of setae/spines along postero-dorsal margin of pleonites'' (character 14, CI50.2, RI50.5; left) and ''uropod I rami-spines'' (character 58, CI50.37, RI50.73; right). Both characters are supposed to be characteristics of ''Orniphargus'' (S. Karaman (1950c)).

Individual and species variation in mixed-species aggregations of harvestmen
<p>This dataset is associated with the published paper Escalante, I, M Domínguez, D Gómez-Ruiz, and G Machado. Benefits and costs of multi-specific aggregations in harvestmen (Arachnida: Opiliones). Frontiers in Ecology and Evolution (DOI 10.3389/fevo.2021.766323). Please refer to the paper for the extensive explanations on the collection, analysis, presentation, and analyses of the data. </p> <p>We provide the first description of mixed-species roosting aggregations of seven species of the genus <em>Prionostemma </em>from Costa Rica. We surveyed several plants (trees and palms) for the presence of harvestmen of seven different species across time (14 days). These harvestmen are frequently found in aggregations. Hence, we also counted the number of individuals in each aggregation. Additionally, we counted the number of legs in each harvestmen, as well as the number of parasitic mite larvae found in the harvestmen's bodies. With all of this information, we were able to explore the effects of the roosting status (solitary/aggregated), the aggregation size, and the species composition of the aggregations (single- or multi-species aggregations) with potential benefits (less damage, i.e., individuals with all of their legs) and costs (a higher parasitic infection).</p>

Silene uralensis aggregate, circumpolar species : dataset, Miseq Illumina RAW READS
<p>This dataset includes 43 samples of circumpolar species included in the <em>Silene uralensis</em> aggregate, sensu http://panarcticflora.org/. Forty-eight low copy nuclear genes were enriched with <em>Silene-</em>specific probes. The samples were sequenced with the Miseq technology from the short read Illumina platform. An excel sheet with samples information is included.</p> <p>Two other datasets are associated to this one, called "Silene uralensis aggregate, circumpolar species : dataset, Novaseq Illumina RAW READS SET 1" on Zenodo 10.5281/zenodo.12699639 and "Silene uralensis aggregate, circumpolar species : dataset, Novaseq Illumina RAW READS SET 2" on Zenodo 10.5281/zenodo.12700012. These three datasets belong to a study about phylogenetics in the circumpolar <em>Silene uralensis</em> aggregate. </p> <div> <div> <div> </div> <div> <div> <div> </div> <div> <p> </p> <p> </p> </div> </div> </div> </div> </div>
Leaf area predicts conspecific spatial aggregation of woody species
<p><strong>Aim:</strong> Addressing how woody plant species are distributed in space can reveal inconspicuous drivers that structure plant communities. The spatial structure of conspecifics varies not only at local scales across co-existing plant species but also at larger biogeographical scales with climatic parameters and habitat properties. The possibility that biogeographical drivers shape the spatial structure of plants, however, has not received sufficient attention.</p> <p><strong>Location:</strong> Global synthesis.</p> <p><strong>Time period:</strong> 1997 - 2022.</p> <p><strong>Major taxa studied:</strong> Woody angiosperms and conifers.</p> <p><strong>Methods:</strong> We carried out a quantitative synthesis to capture the interplay between local scale and larger scale drivers. We modelled conspecific spatial aggregation as a binary response through logistic models and Ripley's L statistics and the distance at which the point process was least random with mixed effects linear models. Our predictors covered a range of plant traits, climatic predictors and descriptors of the habitat.</p> <p><strong>Results:</strong> We hypothesized that plant traits, when summarized by local scale predictors, exceed in importance biogeographical drivers in determining the spatial structure of conspecifics across woody systems. This was only the case in relation to the frequency with which we observe aggregated distributions. The probability of observing spatial aggregation and the intensity of it was higher for plant species with large leaves but further depended on climatic parameters and mycorrhiza.</p> <p><strong>Main Conclusions:</strong> Compared to climatic variables, plant traits perform poorly in explaining the spatial structure of woody plant species, even though leaf area is a decisive plant trait that is related to whether we observe homogenous spatial aggregation and its intensity. Despite the limited variance explained by our models, we found that the spatial structure of woody plants is subject to consistent biogeographical constraints and that these exceed beyond descriptors of individual species, which we captured here through leaf area.</p>
