Ecology and Evolution, Volume 16, Issue 7, July 2026.This study reports the first complete mitogenome of the estuarine clam Potamocorbula amurensis, revealing its phylogenetic position as a sister group to the Myidae–Dreissenidae clade. Molecular dating indicates a Middle Jurassic divergence, and positive selection was detected in the nad5 gene, suggesting mitochondrial adaptations to osmotic stress in ...

Remote measurements and measuring systems : ballast water treatment system
, 2021 Balastne vode su vode koju brod uzima u posebne tankove tijekom svoje plovidbe da bi poboljšao vlastiti stabilitet i ravnomjerno raspodijelio opterećenje na brodski trup, ukoliko to nije moguće napraviti samim teretom.

Coexistence, crossover and extirpation in coalescent communities and ecotones
Oikos, Volume 2026, Issue 7, July 2026.When two ecological communities come into contact, the strength of their mixing determines whether species coexist, extirpate, or extend their ranges. We present analytical formulas and simulations describing these transitions. Specifically, we derive abundance shifts upon community coalescence, identify the critical mixing strength leading to first ...

ELECTROCOAGULATION SYSTEM FOR TREATMENT OF BALLAST WATER
Carpathian Journal of Earth and Environmental SciencesThis study aimed to determine the removal of hazardous materials in ballast water by using an electrocoagulation (EC) system. This research was carried out on January 16 – June 15 2023 in Batam City. Ballast water was supplied by tanker ships anchored at 5 ports in Batam Island, namely Batam Centre, Sekupang, Nongsapura, Telaga Punggur, and Batu Ampar.

Addressing false negatives and positives in eDNA studies
Methods in Ecology and Evolution, Volume 17, Issue 7, Page 1977-2008, July 2026.Abstract Environmental DNA (eDNA) has revolutionized the study of ecology and biodiversity, enabling species detection without direct observation in the environment. However, the implications of detection errors, specifically false positives and false negatives, are poorly reported in eDNA studies, significantly hindering our understanding of the ...

Entomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 670-684, July 2026.We assessed Spodoptera litura (Lepidoptera: Noctuidae) performance on five common pasture plant species. Larvae consumed more dock, plantain and chicory per day than red or white clover, but with lower conversion efficiencies. Feeding on red clover reduced weights and egg laying, and lengthened development times compared with plantain.
