Evidence of a marine larval stage in coastrange sculpin Cottus aleuticus from a small coastal stream in California, USA, based on otolith strontium isotopes

open access: yesJournal of Fish Biology, EarlyView.
Abstract Cottus aleuticus (coastrange sculpin) is one of two North American facultatively amphidromous sculpins, but habitat use during its planktonic larval stage is poorly documented. We analysed strontium isotopes (88Sr and 87Sr/86Sr) in otoliths of 10 adult C. aleuticus from a small coastal California stream.

Long‐term stability of transcrestal sinus augmentation

open access: yesPeriodontology 2000, EarlyView.
Abstract Transcrestal sinus augmentation has emerged as a minimally invasive alternative to lateral window techniques for vertical bone augmentation in the edentulous maxilla. Since its early introduction and modification over the last several decades, this technique has demonstrated predictable outcomes for implant placement in regions with limited ...

An experimentally informed computational model of neurovestibular adaptation to altered gravity

open access: yesExperimental Physiology, EarlyView.
Abstract Transitions to altered gravity environments result in acute sensorimotor impairment for astronauts, leading to serious mission and safety risks in the crucial first moments in a new setting. Our understanding of the time course and severity of impairment in the early stages of adaptation remains limited and confounded by unmonitored head ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

On‐feet isometric bracing maintains cerebral arterial blood velocity during lower body negative pressure via preload augmentation

open access: yesExperimental Physiology, EarlyView.
Abstract Orthostatic stress reduces venous return and stroke volume (SV), risking cerebral hypoperfusion despite autonomic compensation. Although lower‐limb counterpressure manoeuvres improve cerebral perfusion in upright posture, their effects on cerebral blood velocity (CBV) during lower‐body negative pressure (LBNP) and the associated mechanisms are

Estimating Somatic Weight From Total Weight in the European Eel (Anguilla anguilla)

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT Data on the size of an animal is essential when analysing population dynamics, growth rates or the body condition of individuals for size‐structured populations. Two common weight measurements are total body weight and somatic weight. Compared to total weight, somatic weight needs lethal sampling and is more time‐consuming to assess, but can ...

Bioimaging of sense organs and the central nervous system in extant fishes and reptiles in situ: A review

open access: yesThe Anatomical Record, Volume 309, Issue 4, Page 826-852, April 2026.
Bioimaging of the sense organs and brain of fishes and reptiles. Left panel: 3D reconstruction of the head and brain of the deep‐sea viperfish Chauliodus sloani following diceCT. Right panel: A 3D reconstruction of a 70‐day‐old embryo head of the bearded dragon Pogona vitticeps following diceCT, showing the position of the segmented brain within the ...
