Osteological, Biological, and Genetic Consequences of Colonization of Fresh Waters by Marine Cottoid Fishes (Cottidae)

open access: yesIntegrative Zoology, EarlyView.
Lacustrine forms of Triglopsis from North American and European lakes are at different stages of evolution, making them a suitable model for testing hypotheses about evolutionary patterns and rates. An integrative analysis of morphological, genetic, and biological adaptations occurring in lacustrine forms of the genus Triglopsis was carried out.

Salinity and resource availability as drivers of Baltic benthic fungal diversity

open access: yesEnvironmental DNA
Marine biodiversity consists of a complex network of organisms responsible for keeping the ecosystem's balance. Fungi are an understudied group of organisms despite their recognized importance for ecosystem processes and diversity.

Inhibin βB Mediates Oligotrophic Adaptation via Regulating Muscle Satellite Cell Proliferation and Differentiation in Schizopygopsis younghusbandi

open access: yesIntegrative Zoology, EarlyView.
① Nutrient deficiency upregulates inhibin βB, activating SMAD signaling to promote p21. Increased p21 inhibits mcm2/mcm4/mcm5 and cyclin E2, inducing G1‐phase arrest, slowing growth, and reducing energy consumption. ② Inhibin βB also upregulates pdgf‐c, which induces α‐SMA, leading to muscle satellite cell fibrosis.

A validated 3D point‐cloud analysis workflow for the creation of seagrass canopy height models

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Seagrasses support highly productive ecosystems in both temperate and tropical waters and provide essential ecosystem services. Despite their importance, the vertical structure of seagrasses (i.e. the canopy) remains poorly characterised at the microscale, even though it is a strong predictor of ecological processes that influence both ...

Underwater imaging without colour distortions requires RAW capture

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Consumer cameras are not designed to be scientific instruments, yet they are increasingly used in science not just to see, but to measure. This is possible because camera sensors respond approximately linearly to the light they receive, a property that can, in principle, support quantitative measurements of colour.

Mortars From Punic and Hellenistic–Roman Solunto: Materials, Formulations, and Technology

open access: yesArchaeometry, EarlyView.
ABSTRACT This study presents an archaeometric investigation of 18 hydraulic rendering and bedding mortars from Punic and Hellenistic–Roman Solunto (NW Sicily). The research aimed to characterize raw materials, reconstruct manufacturing sequences, and evaluate technological proficiency through mineralogical and petrochemical analyses.

Ceramic Raw Materials and Technological Choices in Iron Age Tyre (Lebanon): A Multiproxy, Fabric‐Based Approach

open access: yesArchaeometry, EarlyView.
ABSTRACT This study presents a systematically integrated, multiproxy characterisation of Iron Age ceramics from Tyre (Lebanon). Ninety‐nine ceramic samples from stratified Iron Age contexts on Tyre's Acropolis, together with a small Late Bronze Age and raw‐clay reference set, were analysed using petrography, microfossil identification, X‐ray ...
