This study examines the invasion dynamics of the predatory invertebrate flatworm Kontikia andersoni, and its impacts on the invertebrate communities of sub‐Antarctic Macquarie Island. Our findings indicate that at higher elevations where K. andersoni is present there are significant reductions in invertebrate richness.

Comparative and Phylogenetic Analyses of Mitochondrial Genomes in Carabidae (Coleoptera: Adephaga)
In this study, six complete mitochondrial genomes (mitogenomes) from the genus Harpalus are reported. Additionally, 13 cases of suspected misidentifications in public Carabidae mitogenomes from GenBank were identified, with potential corrections suggested.

African clawless otters demonstrate dietary plasticity, but terrestrial insects have not previously been documented as a primary prey source in this species. Dietary flexibility and response to shifts in available prey items may offer African clawless otters an advantage in the face of climate change.
