Metabarcoding of Broad‐Diet Nototheniid Fish Stomachs Reveals Newly Detected Antarctic Parasite Signals and Potential Host Associations

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Using 18S rDNA metabarcoding of stomach contents from two Antarctic nototheniid fishes, we detected 242 parasite OTUs. Protists dominated diversity, metazoans dominated abundance, and depth structured assemblages. Novel parasite–host associations and previously unreported pathogenic protists highlight fish metabarcoding as a tool for biodiversity and ...

Protocols for the development of the guidance on the risk assessment of PPP to non‐target arthropods, in‐soil organisms and non‐target terrestrial plants

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract The present document defines the problem formulation, evidence needs and methodological approach agreed by the Environmental Risk Assessment Working Group and the EFSA Panel on Plant Protection Products and their Residues for the Tier 1 risk assessment of the terrestrial ecotoxicology guidance document.

The impacts of biological invasions

Biological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

DNA Metabarcoding Reveals Unexpected Predator–Prey–Microbial Dynamics in the Southern Right Whale (Eubalaena australis)

Molecular Ecology, Volume 35, Issue 12, June 2026.
ABSTRACT Southern right whale (Eubalaena australis; SRW) populations are recovering from the impacts of commercial whaling, however, recovery has been spatially variable, with strong associations between reproduction and prey availability. The diet of SRWs has not been widely examined, and with SRW foraging shifting away from high‐latitude foraging ...

Elevated Temperatures Disrupt Wolbachia‐Induced Feminisation and Reshape Microbial Community Dynamics Across Generations in a Spider Host

Molecular Ecology, Volume 35, Issue 9, May 2026.
ABSTRACT Longitudinal microbial interactions within a host are challenging to study, leading to a focus on constructed microbial communities in vitro settings. Here, we take advantage of a naturally defined microbial community within a spider host to study how elevated temperatures influence microbial dynamics and phenotypes across host generations ...

Drivers of Microbiome Composition Among Helminth Parasites Sharing the Same Insectivorous Bat Host

Molecular Ecology, Volume 35, Issue 10, May 2026.
ABSTRACT Parasitic metazoans are increasingly recognised to form close associations with microbial taxa. Under the holobiont concept, these associations are an eco‐evolutionary unit under joint selection. However, for most parasitic helminth species and particularly those associated with wildlife, these interactions and their effect on parasite ...

Low Ectoparasite Loads and Interactions With Cleaner Fish Among Amphiprion Anemonefish

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Interactions between ectoparasites, reef fishes and cleaner species are well documented; however, anemonefishes (Amphiprioninae) have been largely overlooked in this context. A hypothesis proposed as early as 1869 suggests that anemonefishes may experience reduced ectoparasite loads due to their symbiotic association with venomous host sea ...
