Environmental DNA Reveals the Fish Community Structure Exhibited Instability and Trend of Miniaturization in the Xijiang River Basin of the Guizhou

open access: yesEcology and Evolution, Volume 15, Issue 9, September 2025.
Monitoring of fish communities is of great significance for the management and sustainability of river ecosystems. Environmental DNA (eDNA) metabarcoding technology has been demonstrated to be a highly sensitive biomonitoring tool. Nevertheless, it has seldom been tested in mountainous rivers within the geographically complex Karst region.

S.E.M. observations on plerocercus larvae of Floriceps saccatus Cuvier, 1817 and Molicola horridus (Goodsir, 1841) (Cestoda; Trypanorhyncha) from sunfish (Mola mola)

open access: yesFauna Norvegica, 1987
A topographic description of the plerocercus larva of Floriceps saccatus is given. The larva was found to be covered by palmate or paw-like microtriches, not only on the adherent surface of the bothridia as earlier described from adult trypanorhynch ...

Three new species of blood flukes (Digenea: Aporocotylidae) infecting pufferfishes (Teleostei: Tetraodontidae) from off Bali, Indonesia [PDF]

open access: yes, 2016
We describe three new species of blood flukes (Aporocotylidae) and propose their classification within the genus Psettarium Goto & Ozaki, 1929. All three species were collected from the circulatory systems of pufferfishes caught off Bali, central ...

Die Chemie und Biologie der Tetrodotoxin Naturstofffamilie

open access: yesAngewandte Chemie, Volume 137, Issue 35, August 25, 2025.
Tetrodotoxin ist vor allem als das Gift des Kugelfisches bekannt, einer Delikatesse in der japanischen Küche. Seine Toxizität beruht auf der selektiven Blockade von NaV Kanälen, wie am Beispiel der NaV1.7 Pore dargestellt, wobei das DEKA Motiv hervorgehoben ist, das für die Durchlässigkeit von Natriumionen verantwortlich ist.

The Chemistry and Biology of the Tetrodotoxin Natural Product Family

open access: yesAngewandte Chemie International Edition, Volume 64, Issue 35, August 25, 2025.
Tetrodotoxin is best known as the poison of the pufferfish, which is a delicacy in Japanese cuisine. Its toxicity arises from the selective blockage of NaV channels, which is depicted for the NaV1.7 pore, highlighting the DEKA motif, which permeates sodium ions.
