The Socotra Archipelago (Yemen) is globally recognized for its outstanding biodiversi-ty and endemism, designated on this basis a UNESCO World Heritage Site in 2008. The island underwent long geological and political isolation, ensuring preservation of unique ecosystems un-til the start of the new millennium. Now, Socotra Island is undergoing rapid...

The timely characterization of high-altitude freshwater habitats allows an assessment of the diversity of its biota and provides the basis for monitoring community change. In this study, we investigate the Cladocera fauna of 29 water bodies (pools, freshwater lakes, and surrounding swamps sampled at various occasions between 2005 and 2009) in the R...

Waterfleas (Crustacea: Branchiopoda: Cladocera) are among the most successful invertebrates in current freshwater ecosystems, occupying a wide range of niches worldwide. Cladocerans are an important component of the zooplankton, occur in high abundance, and show a marked degree of morphological diversification and species richness with over 700 ext...

Although phylogeny estimation is notoriously difficult in radiations that occurred several hundred million years ago, phylogenomic approaches offer new ways to examine relationships among ancient lineages and evaluate hypotheses that are key to evolutionary biology. Here we reconstruct the deep-rooted relationships of one of the oldest living arthr...

Question Plant–plant facilitation is a critical ecological mechanism in arid environments, influencing biodiversity and ecosystem resilience globally. Shrubs often serve as nurse species, enhancing tree regeneration and sheltering plant communities, particularly in overgrazed or degraded habitats. In this study, we examine the role of shrubs as nur...

Only a small proportion of the world’s crustacean taxa is adapted to limno-terrestrial microhabitats that are disconnected from conventional surface waterbodies. In rare occasions, water films on terrestrial tropical and subtropical vegetation may also harbour specialised cladocerans. Bryospilus Frey, 1980 (Chydoridae) is the only genus within the...

Fossils require a rigorous process of taxonomical assignment, including a detailed examination of homologies and (syn)apomorphies. However, not all fossils can be identified and forcing enigmatic fossils into an unrelated lineage leads to confusion. A well-founded identification of fossils based on homologies is vital to improve our knowledge of ke...

Daphnia magna is a model organism for several areas of biology, from ecotoxicology to genomics. Like other cladocerans, Daphnia is a cyclical parthenogen: females are able to produce clonal offspring (both male and female) without the need for fertilization. It follows that the two sexes share an identical genome. The differences between the male a...
