Presence and Location of CatSper 1–4, Opioid (μ, δ and κ) and CD44 Receptors in SPERMATOZOA from AOUDAD, IBERIAN IBEX and Mouflon

open access: yesVeterinary Medicine and Science, Volume 11, Issue 4, July 2025.
Spermatozoa from aoudad (Ammotragus lervia), Iberian ibex (Capra pyrenaica) and mouflon (Ovis musimon) express CatSper 1‐4, μ, δ and κ‐opioid receptors and CD44, reflecting a possible role on sperm physiology from wild ruminant species, i.e., motility/hyperactivated motility, capacitation and chemotaxis.

Rapid Metabolic Recovery Following Vigorous Exercise in Burrow-Dwelling Larval Sea Lampreys (\u3cem\u3ePetromyzon marinus\u3c/em\u3e) [PDF]

open access: yes, 2001
Although the majority of the sea lamprey’s (Petromyzon marinus) life cycle is spent as a burrow-dwelling larva, or ammocoete, surprisingly little is known about intermediary metabolism in this stage of the lamprey’s life history.

Successful Transmission and Isolation of a Fungal Pathogen From Wild Frogs to a Captive Amphibian Model Species: Fine Scale Pathogen Genetic Diversity and Infection‐Induced Changes in Skin Bacteria

open access: yesEnvironmental Microbiology, Volume 27, Issue 7, July 2025.
The isolation of Batrachochytrium dendrobatidis (Bd) from low‐load wild amphibians revealed multiple genotypes, including a potential hybrid, highlighting ongoing pathogen genetic mixing in natural environments. Additionally, Bd infection induced skin microbiome shifts in Hymenochirus boettgeri, demonstrating its utility as a model for studying ...

Mixed‐Species Fish Shoals: Any Port in a Storm?

open access: yesFish and Fisheries, Volume 26, Issue 4, Page 623-635, July 2025.
ABSTRACT Mixed‐species fish shoals are common, and form for a variety of reasons. We suggest that short term mixed‐species shoals, that persist for minutes or hours, might form because lone individuals (or small groups) of one species might benefit from joining larger groups of heterospecifics to reduce predation risk.

Another Novel Feeding Mode in the Labridae: Juvenile Tuskfish Fan Sand With Vigorous Single Pectoral Fin Swipes

open access: yesMarine Ecology, Volume 46, Issue 4, July/August 2025.
ABSTRACT Fishes exhibit a range of feeding modes and strategies to forage in and on sand habitat. Here, we describe a novel feeding mode, whereby small juvenile baldchin groper, Choerodon rubescens (⁓65–100 mm TL), vigorously forward sweeps the benthos with a single pectoral fin to reveal small benthic prey and visually scans the immediate benthos on ...

The eyes of suckermouth armoured catfish (Loricariidae, subfamily Hypostomus): pupil response, lenticular longitudinal spherical aberration and retinal topography [PDF]

open access: yes, 2002
The dilated, round pupils of a species of suckermouth armoured catfish (Liposarcus pardalis) constrict slowly on illumination (over 35-40 min) to form crescent-shaped apertures. Ray tracing of He-Ne laser beams shows that the lenses of a related species (
