Competent Non‐Native Alternative Host Reduces Infection Success in a Generalist Parasite

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
In this study, we experimentally assessed how the addition of a non‐native alternative host affects the infection success of the larval generalist trematode, Diplostomum pseudospathaceum, in fish intermediate hosts. Our results demonstrate that the presence of alternative hosts, especially the non‐native ones, can reduce parasite transmission through ...

THE VARIATION OF TWO SPECIES OF LYMNAEA [PDF]

open access: yesGenetics, 1935
The problem of the effects of isolation in relation to the establishment of subspecies and local races has been studied by many workers since the time of DARWIN and WALLACE, but in most instances it has been attacked only from the standpoint of geographical speciation.

Inter‐Annual Variation in Alpha and Beta Diversity of Benthic Macroinvertebrate Communities in Agricultural Ditches

open access: yesRiver Research and Applications, Volume 42, Issue 5, Page 997-1010, June 2026.
ABSTRACT Ditches are essential elements of the agricultural landscape because of their role as habitat or refuge for aquatic species, especially in homogenized and intensively cultivated areas. However, data on the biodiversity associated with agricultural ditches, and its variation over time, are underrepresented in ecological research.

Conkazal‐M1 from the MKAVA family of conotoxins: A dual‐function protease inhibitor and neuroactive peptide

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
Abstract Marine cone snails produce a diverse array of bioactive peptides, known as conotoxins, in their venom. Given their high target potency and specificity, conotoxins are attractive compounds for the development of precision research tools and pharmacological agents.

Mapping molluscan endocrinology: a systematic and critical appraisal

open access: yesBiological Reviews, Volume 101, Issue 2, Page 970-1002, April 2026.
ABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...

Selective Depletion of Autoreactive Plasma Cells as a Novel Strategy to Treat Acetylcholine Receptor Antibody‐Positive Myasthenia Gravis

open access: yesEuropean Journal of Immunology, Volume 56, Issue 4, April 2026.
Current plasma cell–targeting therapies lack antigen specificity. Using an antibody‐mediated cytotoxicity engager (ACE) targeting the α‐subunit of the extracellular domain of the human acetylcholine receptor (hAChR αECD), we selectively depleted pathogenic antibody‐secreting cells in a myasthenia gravis model, reducing autoantibody titers and disease ...

Prioritising research on endocrine disruption in the marine environment: a global perspective

open access: yesBiological Reviews, Volume 101, Issue 2, Page 848-868, April 2026.
ABSTRACT A healthy ocean is a crucial life support system that regulates the global climate, is a source of oxygen and supports major economic activities. A vast and understudied biodiversity from micro‐ to macro‐organisms is integral to ocean health.

Pathological and Epidemiological Assessment of Trematode Burden in Ruminants From Central Ethiopia

open access: yesVeterinary Medicine and Science, Volume 12, Issue 2, March 2026.
• Trematode infections were highly prevalent (49.22%) among ruminants in central Ethiopia, with fasciolosis (32.42%) and paramphistomosis (16.80%) strongly associated with poor body condition and specific geographic origins. • Histopathological and haematological analyses revealed severe liver and intestinal damage, anaemia, and elevated liver enzymes,
