Clarifying the Labrisomus Conundrum: Deep Divergence, Cryptic Lineages, and a Genetic Melting Pot in the Atlantic Ocean (Teleostei, Labrisomidae)

Journal of Biogeography, Volume 53, Issue 8, August 2026.
ABSTRACT Aim We evaluate the phylogenetic relationships and taxonomic validity of Atlantic species of Labrisomus, identifying the lineages currently assigned to L. nuchipinnis, and assessing the role of biogeographic barriers in shaping the evolutionary history and geographic distribution of the genus. Location Atlantic Ocean.

White Is a New Shade of Blue Carbon: A Case Study of a Traditional Salt Production Pond That is a Net Carbon Sink

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract To address for the first time the carbon budget of traditional salterns, we measured the diel, seasonal, and spatial variability of water‐air CO2‐eq fluxes (CH4 and CO2) and the Organic Carbon (OC) stock and burial rate in the sediment. Temperature, salinity, dissolved oxygen, pH and wind were assessed as potential environmental drivers of the

A new method to control the invasive sun corals (Tubastraea spp.): Underwater compressed‐air blasting

Ecological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
Underwater compressed‐air blasting is a novel method developed to control invasive sun corals (Tubastraea spp.). The technique removes coral soft tissue without fragmenting colonies, reducing the risk of regeneration and accidental spread. This approach offers a safer and practical tool for managing invasive corals in natural reefs and biofouling ...

An updated classification of growth forms in non‐geniculate coralline algae (Corallinophycidae, Rhodophyta)

Journal of Phycology, Volume 62, Issue 2, Page 490-511, April 2026.
Abstract The current challenge of defining growth forms in the non‐geniculate coralline red algae was addressed. Since the 19th century, those who have worked on this large and globally distributed group of algae have tried to summarize and systematically describe their growth forms. This effort resulted in a plethora of terms, which could sometimes be

Adapting the growth‐form concept to geniculate coralline algae (Corallinales, Rhodophyta)

Journal of Phycology, Volume 62, Issue 2, Page 512-532, April 2026.
Abstract Geniculate coralline algae (Corallinales, Rhodophyta) are a diverse group of calcifying macroalgae, loosely united by flexible upright axes formed by alternating calcified (intergenicula) and uncalcified segments (genicula), a trait that has independently arisen several times.
