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

Integrative 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

Methods 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 ...

Spatial Prioritization for the Zonation of a Reef System in a New Remote Marine Protected Area in the Southern Gulf of Mexico

Diversity
Coral reef ecosystems are biodiversity hotspots that provide essential ecological and environmental services but are increasingly threatened by anthropogenic pressure and climate change.

First Insights on Photoreceptor Organ Ultrastructure in Marine Chaetonotida (Gastrotricha): Species of Xenotrichula and Draculiciteria (Xenotrichulidae)

Acta Zoologica, EarlyView.
ABSTRACT Marine gastrotrichs inhabit sediments with limited available light, yet evidence suggests that photoreceptor organs are present throughout the phylum Gastrotricha. Here, we confirm this proposition with ultrastructural descriptions of photoreceptive organs in two species of Xenotrichulidae (Order Chaetonotida) that lack pigmented ocelli ...

AI‐Assisted Morphometric Analysis and Molecular Phylogeny for a Dactylogyrid (Monopisthocotyla) Skin Parasite of an Ornamental Crenuchid Fish From Brazil

Acta Zoologica, EarlyView.
ABSTRACT This study presents a formal description and taxonomic appraisal of Cacatuocotyle adrianoi sp. n., a Neotropical parasite belonging to the family Dactylogyridae, integrating AI‐assisted morphometric analyses, molecular data, and phylogenetic reconstruction. Phylogenetic analyses recovered Cacatuocotyle adrianoi sp. n.

Absence of a Hectocotylus and Associated Mating Behaviour in the Paintpot Cuttlefish Ascarosepion tullbergi

Acta Zoologica, EarlyView.
ABSTRACT A hectocotylus is a sexually modified arm used by males of some cephalopod species to transfer spermatophores to females. In most cuttlefish (Sepiidae), it corresponds to the left arm IV, in which basal suckers are reduced or absent; this modification is thought to facilitate sperm transfer without premature rupture, which could be caused by ...

Multitemporal Analysis of Aboveground Carbon Stock of Seagrass Meadows using Sentinel-2 in the Coastal Area of Bontang City in 2020-2024

JGEET: Journal of Geoscience, Engineering, Environment and Technology
Seagrass is one of the ecosystems that absorbs large amounts of carbon in the blue carbon ecosystem. This ecosystem also has many benefits, such as becoming the habitat for fish and improving water quality.

Same Same, but Different: A Glossary of Carcino‐Entomology as a Basis for an Improved Communication and for a Modern View of Carcinology Encompassing Entomology

Acta Zoologica, EarlyView.
ABSTRACT One core aspect of science is communication, both among researchers as well as with the public. For successful communication, it is crucial that the terminology used is clear to avoid misunderstandings. Especially when researchers working on different groups of organisms communicate, they often use different terms for similar morphological ...

Morphological and Morphometric Characterisation of Selected Camarodont Sea Urchin (Echinoidea: Camarodonta) Pedicellariae (Paracentrotus lividus, Psammechinus miliaris and Echinus esculentus)

Acta Zoologica, EarlyView.
ABSTRACT Pedicellariae are small appendages on the surface of the echinoid test, involved in defence, cleaning, and locomotion. Pedicellariae in three species of camarodont sea urchins common in UK waters (Paracentrotus lividus [Lamarck, 1816], Psammechinus miliaris [P.L.S Müller, 1771] and Echinus esculentus [Linnaeus, 1758]) are the focus of this ...

Chironomid‐based summer temperature reconstruction of the Eemian–Weichselian transition at Lichtenberg, northern Germany

Boreas, EarlyView.
Understanding the temperature variability of past interglacial cycles is essential to predict future climates. We present a new summer temperature reconstruction, based on the subfossil chironomid record from a small palaeolake adjacent to the Middle Palaeolithic site of Lichtenberg, northern Germany. The record spans from the Saalian late glacial over
