ABSTRACT Subterranean ecosystems in urban environments are exposed to multiple anthropogenic stressors that compromise groundwater quality and biodiversity. Rising groundwater temperatures, oxygen depletion, hydraulic disturbance and chemical contamination are among the main pressures.

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 ...

ABSTRACT Biological invasions pose major threats to ecosystems, with aquatic habitats particularly vulnerable due to high connectivity and biodiversity. The Ponto‐Caspian region is widely recognised as a major source of highly invasive non‐native aquatic species, yet a global synthesis of their spatial, taxonomic and temporal invasion patterns has been

Fourty seven specimens of Pelophylax ridibundus were collected in the vicinity of Shiraz, Fars Province, Iran in 1972. Fourteen helminth species were found, eight digeneans (Diplodiscus subclavatus, Halipegus alhaussaini, Haematoloechus similis ...

Progress and Challenges in Phylogenomics and Genomics of Lophotrochozoa/Spiralia
ABSTRACT Lophotrochozoa is one of the three major bilaterian groups comprising more than half of the bilaterian phyla. Lophotrochozoa includes among others Mollusca, Annelida, Platyhelminthes and Rotifera. Despite representing such a large proportion of animal diversity, they are historically understudied and genomic resources have been scarce. However,

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.

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

Sampling effort to characterize estuarine macroinfaunal communities in patchy habitats
Abstract Estuarine benthic macroinfauna have aggregated, patchy distributions, making accurate community measurements dependent upon sampling scales. The purpose of this study is to determine the appropriate core sizes and sampling effort needed to characterize benthic infaunal communities in Corpus Christi Bay, Texas, USA.

Molecular markers in studies on fish parasites (Platyhelminthes): Review
Studies with molecular markers are currently more common for all groups of living organisms. Molecular techniques used in Platyhelminthes parasites of fishes do not merely reveal complex life cycles, but are important for species distinction and the ...
