Arthropods moving on large horizontal branches of old oaks (Quercus robur L.) in seven oak woodlands, SW Finland, were studied using a new trap type. The most abundant groups included Formicidae (Hym.), Oribatida (Acari), Thysanoptera, Nematocera (Dipt.), Collembola, Auchenorrhyncha (Hom.), Coleoptera, Araneae, Psocoptera and Hemiptera. The last three groups showed the least intersite variation in numbers of individuals. About 120 abundant, rare and other interesting species of Diplopoda (4 species mentioned), Chilopoda (2), Araneae (19), Opiliones (4), Pseudoscorpionida (1), Oribatida (9), Psocoptera (9), Blattodea (1), Neuroptera (1), Homoptera (10), Heteroptera (13), Coleoptera (25), Lepidoptera (14) and Formicidae (6) are listed, and the new trap is described.

1. Macro-detritivores are important fragmenters performing a first step in the ecosystem process of nutrient cycling. Woodlice and millipedes are important representatives of this group and their ecology and niche requirements are often regarded as very similar. However, it is unclear whether there is a difference in temporal activity throughout the year between both groups, possibly leading to temporal complementarity for leaf litter breakdown, and whether patterns of temporal variation in activity are consistent across different habitat types.

2. We studied year-round pitfall-trap data of woodlice and millipedes from an old sand quarry with a high habitat heterogeneity.

3. Our results indicate that there is high temporal complementarity between both detritivore taxa, with millipede activity-density peaking in spring, while woodlice showing a peak in summer. Interestingly, timing of activity depended on habitat openness. Millipedes peak first in open habitat and later in closed habitat, while woodlice showed the opposite pattern.

4. Temporal turnover in community composition was high and of similar magnitude as spatial turnover in community composition across this relatively small scale of our study area.

5. We conclude that, although woodlice and millipedes show comparable habitat preferences, their temporal activity patterns show the potential for temporal complementarity for litter breakdown.

Summary: Currently 73 species from 25 genera and 3 families (Blaniulidae, Julidae, Nemasomatidae) are listed for Austria. Seven of these are classified as exotics, which \– according to current knowledge \– are only known from anthropogenic habitats, representing introduced and/or ephemerous species.

No end to debates on relationships among the four major myriapod subgroups}, journal = {BMC Evolutionary Biology}, volume = {20}, year = {2020}, month = {04/11/2020}, pages = {1-15}, abstract = {

Background: Phylogenetic relationships among the myriapod subgroups Chilopoda, Diplopoda, Symphyla and Pauropoda are still not robustly resolved. The first phylogenomic study covering all subgroups resolved phylogenetic relationships congruently to morphological evidence but is in conflict with most previously published phylogenetic trees based on diverse molecular data. Outgroup choice and long-branch attraction effects were stated as possible explanations for these incongruencies. In this study, we addressed these issues by extending the myriapod and outgroup taxon sampling using transcriptome data.

Results: We generated new transcriptome data of 42 panarthropod species, including all four myriapod subgroups and additional outgroup taxa. Our taxon sampling was complemented by published transcriptome and genome data resulting in a supermatrix covering 59 species. We compiled two data sets, the first with a full coverage of genes per species (292 single-copy protein-coding genes), the second with a less stringent coverage (988 genes). We inferred phylogenetic relationships among myriapods using different data types, tree inference, and quartet computation approaches. Our results unambiguously support monophyletic Mandibulata and Myriapoda. Our analyses clearly showed that there is strong signal for a single unrooted topology, but a sensitivity of the position of the internal root on the choice of outgroups. However, we observe strong evidence for a clade Pauropoda+Symphyla, as well as for a clade Chilopoda+Diplopoda.

Conclusions: Our best quartet topology is incongruent with current morphological phylogenies which were supported in another phylogenomic study. AU tests and quartet mapping reject the quartet topology congruent to trees inferred with morphological characters. Moreover, quartet mapping shows that confounding signal present in the data set is sufficient to explain the weak signal for the quartet topology derived from morphological characters. Although outgroup choice affects results, our study could narrow possible trees to derivatives of a single quartet topology. For highly disputed relationships, we propose to apply a series of tests (AU and quartet mapping), since results of such tests allow to narrow down possible relationships and to rule out confounding signal.
