Flatworm nerve-muscle: structural and functional analysis

open access: yes, 2004
Platyhelminthes occupy a unique position in nerve-muscle evolution, being the most primitive of metazoan phyla. Essentially, their nervous system consists of an archaic brain and associated pairs of longitudinal nerve cords cross-linked as an orthogon by

First record of the New Guinea flatworm Platydemus manokwari (Platyhelminthes, Geoplanidae) as an alien species in Hong Kong Island, China [PDF]

open access: yesZooKeys, 2019
The New Guinea flatworm (Platydemus manokwari) caused extinction of the native land snails on several Pacific island in past decades, and therefore it has been listed among the top 100 of the world’s worst invasive alien species.

A global assessment of abyssal–hadal vermiform lebensspuren: Functional consistency with depth

open access: yesLimnology and Oceanography, Volume 71, Issue 6, June 2026.
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

Aosta Valley animal cancer registry: A collaborative initiative for monitoring cancer burden in animals

open access: yesVeterinary Record Open, Volume 13, Issue 1, June 2026.
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.

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

open access: yesVeterinary 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.

The stem cell system of the basal flatworm Macrostomum lignano

open access: yes, 2008
The scope of this review is to introduce the free-living flatworm Macrostomum lignano as an excellent model organism to address questions of platyhelminth stem cell biology. First, we sketch the historical origin of flatworm stem cell research.

The exceptional stem cell system of Macrostomum lignano: Screening for gene expression and studying cell proliferation by hydroxyurea treatment and irradiation

open access: yesFrontiers in Zoology, 2007
Background Flatworms are characterized by an outstanding stem cell system. These stem cells (neoblasts) can give rise to all cell types including germ cells and power the exceptional regenerative capacity of many flatworm species.

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

open access: yesMolecular 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 ...
