Data from: Soil arthropod communities associated with Berberis thunbergii invasion in a temperate deciduous forest harbor more detritivores
<ol> <li><span>Barberry (<em>Berberis</em> <em>thunbergii</em>) is a widely established invasive shrub in temperate forests of the northeastern U.S. with the potential to alter soil arthropod communities through changes to soil nutrient cycling and acidity.</span></li> <li><span>We compared soil arthropod taxa and functional feeding groups between invaded and nearby control areas in a paired observational survey.</span></li> <li><span>Community ordination analysis suggested minimal differences between barberry and control samples. In contrast, pairwise differences revealed elevated densities of multiple taxa in barberry-invaded soils. </span></li> <li><span>Among taxa that were able to be defined by functional feeding group and were collected at higher densities under barberry, all were detritivores. For example, barberry-invaded soils harbored an average of 40% more Isopoda and more than twice as many Diplopoda per unit dry compared to control samples. Differences we observed between barberry and control samples despite the limited study spatiotemporal scope demonstrate the potential for invasions to restructure soil arthropod communities.</span></li> <li><span>Observed patterns potentially reflect elevated leaf litter decomposition rates associated with the invasion; results also highlight the need to integrate site-specific environmental attributes when assessing the impact of invading plants on soil ecosystems.</span></li> </ol>

Data from: Towards accurate species-level metabarcoding of arthropod communities from the tropical forest canopy
Metabarcoding of arthropod communities can be used for assessing species diversity in tropical forests but the methodology requires validation for accurate and repeatable species occurrences in complex mixtures. This study investigates how the composition of ecological samples affects the accuracy of species recovery. Starting with field-collected bulk samples from the tropical canopy, the recovery of specimens was tested for subsets of different body sizes and major taxa, by assembling these subsets into increasingly complex composite pools. After metabarcoding, we track whether richness, diversity and most importantly composition of any size class or taxonomic subset is affected by the presence of other subsets in the mixture. Operational Taxonomic Units (OTUs) greatly exceeded the number of morphospecies in most taxa, even under very stringent sequencing read filtering. There was no significant effect on the recovered OTU richness of small and medium-sized arthropods when metabarcoded alongside larger arthropods, despite substantial biomass differences in the mixture. The recovery of taxonomic subsets was not generally influenced by the presence of other taxa, although with some exceptions likely due to primer mismatches. Considerable compositional variation within size and taxon-based subcommunities were evident resulting in high beta diversity among samples from within a single tree canopy, but this beta diversity was not affected by experimental manipulation. We conclude that OTU recovery in complex arthropod communities, with sufficient sequencing depth and within reasonable size ranges, is not skewed by variable biomass of the constituent species. This could remove the need for time-intensive manual sorting prior to metabarcoding. However, there remains a chance of taxonomic bias, which may be primer-dependent. There will never be a panacea primer; instead, metabarcoding studies should carefully consider whether the aim is broad-scale turnover, in which case these biases may not be important, or species lists, in which case separate PCRs and sequencing might be necessary. OTU number inflation remains an issue in metabarcoding and requires bioinformatic development, particularly in read filtering and OTU clustering, and/or greater use of species-identifying sequences generated outside of bulk sequencing.

Mixed-species flocking is associated with low arthropod detectability and increased foraging efficiency by Yungas forest birds in Argentina
<p class="CuerpoB"><span>Mixed-species flocks presumably provide birds with antipredator and foraging benefits. The foraging benefits hypothesis predicts that a reduction in arthropod abundance will trigger flocking activity; however, flocking activity may also be influenced by the difficulty of detecting arthropods, a seldom explored possibility. We found that environmental traits (temperature and foliage density) combined with arthropod abundance explained arthropod detection by birds in the Yungas foothill forest of NW Argentina. Prey detection was inversely related to ambient temperature and foliage density while positively associated with arthropod abundance. Based on this result, we built a </span><span>structural equation model </span><span>using a latent proxy variable for arthropod detectability, arthropod crypsis, integrating ambient temperature, foliage density, and proportion of immature arthropods. This model allowed us to compare the relative importance of arthropod abundance and the difficulty in detecting prey items as predictors of flocking propensity. After two years of studying 129 mixed-species flocks, 1,344 bird foraging sequences, and 25,591 arthropod captures,</span> <span>we found that the flocking propensity of birds was only significantly correlated with arthropod detectability and not with arthropod abundance. </span>Flocking propensity peaked when the arthropod community was comprised of proportionately more immature and non-flying arthropods, the temperature was low, and the foliage cover was more dense; all factors are contributing to a low arthropod detectability. <span>Finally, we evaluated whether joining mixed-species flocks provided foraging benefits such as increased foraging efficiency. Individuals benefited from joining flocks by an average increase of their prey-capture attempt rate of 40%, while the search rate increased by 16%. Our results add a new perspective on the drivers of mixed-species flocking by showing that the capacity to find prey items may have a more significant effect than prey abundance per se.</span></p>
