From Nest Box to Neighborhood: Patterns of Island Biodiversity Characterized Through eDNA From Little Blue Penguin (Eudyptula minor) Nest Boxes

open access: yesEnvironmental DNA, Volume 8, Issue 3, May–June 2026.
There are many environmental DNA (eDNA) sources within and around a seabird nest. These DNA traces from soil, plant material, feathers, feces, and other nest components enable detection of a wide range of taxa, including plants, fungi, insects, arachnids, mollusks, reptiles, and other vertebrates. Here, we used DNA from nest box feces to obtain signals

The in vivo transcriptome of Schistosoma mansoni in the prominent vector species Biomphalaria pfeifferi with supporting observations from Biomphalaria glabrata. [PDF]

open access: yes, 2019
BackgroundThe full scope of the genes expressed by schistosomes during intramolluscan development has yet to be characterized. Understanding the gene products deployed by larval schistosomes in their snail hosts will provide insights into their ...

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.

Forecasting the Risk of Reinvasion by the Giant African Snail in Ogasawara, Japan

open access: yesBiotropica, Volume 58, Issue 3, May 2026.
This study used SDMs constructed in multiple regions to predict the suitable habitats of Achatina fulica on Chichijima in the Ogasawara Islands. The model constructed on another island with a wide distribution range showed the highest predictive accuracy.

Drivers of Microbiome Composition Among Helminth Parasites Sharing the Same Insectivorous Bat Host

open access: yesMolecular Ecology, Volume 35, Issue 10, May 2026.
ABSTRACT Parasitic metazoans are increasingly recognised to form close associations with microbial taxa. Under the holobiont concept, these associations are an eco‐evolutionary unit under joint selection. However, for most parasitic helminth species and particularly those associated with wildlife, these interactions and their effect on parasite ...

Developmental diversity in free-living flatworms

open access: yesEvoDevo, 2012
Flatworm embryology has attracted attention since the early beginnings of comparative evolutionary biology. Considered for a long time the most basal bilaterians, the Platyhelminthes (excluding Acoelomorpha) are now robustly placed within the Spiralia ...

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

open access: yes, 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 ...

A Whole‐Genome Investigation of Mitonuclear Discordance in the Trematode Parasite Atriophallophorus winterbourni

open access: yesMolecular Ecology, Volume 35, Issue 10, May 2026.
ABSTRACT Faster evolution of mitochondrial genomes relative to nuclear genomes creates selective pressure on nuclear genes involved in mitochondrial function to preserve mitonuclear compatibility required for energy production. In isolated populations, such coevolution occurs independently.

Substrate for Thyroid Hormone Synthesis: Biochemistry, Evolution, and Physiology

open access: yesThe FASEB Journal, Volume 40, Issue 8, 30 April 2026.
Two proposed sequence of events for thyroxine formation in patients expressing mutant thyroglobulin. (A) (1) TSH stimulation drives expression of misfolded TG. (2) Unremitting ER stress. (3) Stress‐induced cell death. (4) Dead thyrocytes release their contents. (5) The contents become iodinated. (6) Forming thyroxine.
