The last ice age considerably influenced distribution patterns of extant species of plants and animals, with some of them now inhabiting disjunct areas in the subarctic/arctic and alpine regions. This arctic-alpine distribution is characteristic for many cold-adapted species with a limited dispersal ability and can be found in many invertebrate taxa, including ground beetles. The ground beetle Eschscholtz, 1823 of the subgenus was previously known to have a holarctic-circumpolar distribution, in Europe reaching its southern borders in Wales and southern Scandinavia. Here, we report the first findings of this species from the Austrian Ötztal Alps, representing also the southernmost edge of its currently known distribution, confirmed by the comparison of morphological characters to other species and DNA barcoding data. Molecular data revealed a separation of the Austrian and Finish specimens with limited to no gene flow at all. Furthermore, we present the first data on habitat preference and seasonality of in the Austrian Alps.

Microplastics (MPs) are a growing problem worldwide. Soils are long-term storage sinks of MPs because of the many pathways they enter the soil and their long degradation period. Knowing how MPs influence soil organisms, the effects of organisms on the fate of MPs, and what this means for soil additions, losses, transformations, and translocations is paramount.

These forelands offer unique experimental settings to explore how global warming impacts ecosystems, particularly for highly climate-sensitive arthropods. Understanding these impacts can help anticipate future biodiversity and ecosystem changes under ongoing warming scenarios.

Article Synopsis
- Lack of knowledge about species distribution hinders large-scale biodiversity studies, often reflecting only where sampling has occurred.
- This study focuses on ground beetles and tiger beetles in El Salvador, reporting findings from literature review, fieldwork, and collections.
- The article identifies 66 species across eight subfamilies and aims to encourage further research into the taxonomy and ecology of these beetles in the region.
