The spread of non‐native species
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera
In rotifers, ParaHox genes show a dispersed genomic organization, with Xlox absent across gnathiferans. Exclusive neuronal expression of Gsx and Cdx reveals that ancestral ParaHox genes coordinated neural and epithelial development beyond gut patterning, suggesting an integrated role in early bilaterian body plan organization.

Abstract Spring ecosystems in arid regions often serve as crucial biodiversity hotspots by providing some of the only reliable sources of surface water. However, anthropogenic activities and climate change have severely degraded spring ecosystems worldwide, emphasizing the need for large‐scale multidisciplinary studies informing conservation efforts ...

Constraining the Deep Origin of Parasitic Flatworms and Host-Interactions with Fossil Evidence
Novel fossil discoveries have contributed to our understanding of the evolutionary appearance of parasitism in flatworms. Furthermore, genetic analyses with greater coverage have shifted our views on the coevolution of parasitic flatworms and their hosts.

A global assessment of abyssal–hadal vermiform lebensspuren: Functional consistency with depth
Abstract Lebensspuren—sedimentary traces produced by benthic organisms—are widespread on deep‐sea floors but remain infrequently reported from abyssal (~ 3000–6000) and hadal (> 6000 m) environments. Here, we present the most comprehensive assessment of abyssal–hadal vermiform lebensspuren to date, spanning multiple ocean basins and reaching full‐ocean

Abstract Background Animal cancer registry data are important for monitoring animal health, for prevention and research in veterinary medicine, and for comparative oncology. Since people and animals share the same environment and are exposed to many common risk factors, cancer patterns in animals may have a sentinel function for human health.

Abstract Background The giant African land snail (Lissachatina fulica), an invasive species with significant medical, agricultural and economic importance, is abundant in urban areas of Kota Samarahan, Sarawak. The proximity between humans and the snail may increase the risk of pathogen transmission.
