Protura and molecular phylogenetics: status quo of a young love
Protura are among the latecomers to molecular phylogenetics. The first sequences were published about a decade ago; since then relatively little additional data has been collected. Nonetheless, the available molecular phylogenetic analyses have provided

Identification and character analysis of the Acerentomidae (Protura) of the northeastern Palearctic (Protura: Acerentomidae) [PDF]
This paper is a summary of proturan fauna from Siberia and the Russian Far East, collectively termed the northeastern Palearctic. Special attention is given to the analysis of Acerentomidae, which is extraordinarily diverse in these regions (31 species). A key to species and a brief exposition of distribution of each genus are provided. A redescription

Biodiversity in mountain soils above the treeline
ABSTRACT Biological diversity in mountain ecosystems has been increasingly studied over the last decade. This is also the case for mountain soils, but no study to date has provided an overall synthesis of the current state of knowledge. Here we fill this gap with a first global analysis of published research on cryptogams, microorganisms, and fauna in ...

Canadian goldenrod (Solidago canadensis) invasion had taxon‐dependent effects on myriapods (Arthropoda: Myriapoda) in a protected urban meadow in Budapest, Hungary. Primary consumers such as millipedes and symphylans seemed to be more affected by the invasion than predators. Centipede assemblages were only affected by soil moisture and not by invasion.

Read the free Plain Language Summary for this article on the Journal blog. Abstract The introduction of non‐native tree species has become a global concern and may disrupt native communities and related ecosystem functions. Soil food webs regulate organic matter decomposition and nutrient cycling in forests with their feeding activities, but evaluating

We present a multimodal anatomy of the male genitalia of the bullet ant, Paraponera clavata. Using this as a model system, we expand and refine on the 5‐category system of homology classification proposed by Meneganzin et al. (2024) and we present evidence supporting the penis‐coxopod theory of male genitalic homology in male insects. Abstract The male

How pterygotid sea scorpions used their tripartite elongate cheliceres to get prey items close to the mouth region remains a conundrum. We applied four different 3D kinematic settings with regard to insertion and orientation of the cheliceres to examine the most likely way this was realized.

A new, simplified, drying protocol to prepare tardigrades for scanning electron microscopy
Here a cheap, safe, and fast new method for Tardigrada preparation for scanning electron microscope (SEM) is proposed. The new protocol allows to minimize the number of animals sacrificed for SEM studies and is potentially applicable to the study of other meiofaunal soft‐bodied taxa.
