Incorporating environmental DNA metabarcoding for improved benthic biodiversity and habitat mapping

Remote Sensing in Ecology and Conservation, Volume 12, Issue 3, Page 444-461, June 2026.
Seafloor imagery is commonly used to collect information about the distribution of benthic organisms in order to generate habitat and biodiversity maps. Recent advances in genomics (e.g., environmental DNA; eDNA) show potential to complement video surveys for habitat mapping, but there have been few examples testing this.

Zoonotic risks in urban areas: Prevalence of helminth parasites in urban populations of Lissachatina fulica in Sarawak, Malaysia

Veterinary Record Open, Volume 13, Issue 1, June 2026.
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.

Freshwater Navigation Is Linked to Non‐Native Species Distributions Across Spatial Scales

Diversity and Distributions, Volume 32, Issue 6, June 2026.
ABSTRACT Aim Invasive species are among the most important drivers of native species declines, and cause serious economic and ecological costs. Globally, Europe is a hotspot for freshwater non‐native species, especially among macroinvertebrates and fish, and inland navigation is thought to be a major driver of their spread. However, the degree to which

Helminths of the Eurasian marsh frog, Pelophylax ridibundus (Pallas, 1771) (Anura: Ranidae), from the Shiraz region, southwestern Iran

Helminthologia, 2019
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 ...

Intracellular immunohistochemical detection of tetrodotoxin in Pleurobranchaea maculata (Gastropoda) and Stylochoplana sp. (Turbellaria) [PDF]

, 2015
Tetrodotoxin (TTX), is a potent neurotoxin targeting sodium channels that has been identified in multiple marine and terrestrial organisms. It was recently detected in the Opisthobranch Pleurobranchaea maculata and a Platyhelminthes Stylochoplana sp ...

Native and Non‐Native Populations Respond Unevenly to River Barrier Removals

Global Change Biology, Volume 32, Issue 6, June 2026.
While barrier removals restore river connectivity and promote recovery of native populations, they may also facilitate non‐native species, creating a ‘connectivity conundrum’. Using a systematic review and meta‐analysis, we show that both native and non‐native populations can benefit from barrier removal, with outcomes being context‐dependent ...

Physiological evaluation of the behavior and epidermis of freshwater planarians (Girardia tigrina and Girardia sp.) exposed to stressors

Biology Open, 2018
Planarians are metazoan freshwater flatworms which are free-living organisms. Their body has pluripotent stem cell promoters of tissue regeneration capacity.

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 ...

Characterization of the Hox patterning genes in acoel flatworms [PDF]

, 2010
[eng] One of the main issues in animal evolution deal with the transition from radial organisms (Cnidaria and Ctnenophora), with only one axis of symmetry, the Oral-Aboral (OA) axis, to bilateral organism (Bilateria), bearing two orthogonal body axes ...
