A comprehensive survey of cryptic molluscs associated with autonomous reef monitoring structures (ARMS) in Trindade Island (South Atlantic)

Lucas Nobrega Delcistia, Luiza Soares Ferreira Guimarães, Marcel Sabino Miranda, Flávio Dias Passos et autres

Cryptic biodiversity in marine ecosystems remains largely underestimated due to the inherent difficulty of sampling organisms inhabiting reef microhabitats without causing significant environmental disturbance. This knowledge gap is particularly evident on highly isolated Brazilian oceanic islands, where cryptic invertebrates are still poorly …

The pink Amazon?’ Metabarcoding reveals Rhodolith beds as hidden hotspots of global marine biodiversity

Pedro A. S. Longo, Gustavo M. Mori, Cintia P. Targueta, Mariana P. de C. Telles et autres

Rhodoliths are key foundation species in marine ecosystems, enhancing benthic structural complexity and supporting high biodiversity. However, much of the diversity associated with rhodolith beds remains cryptic, difficult to access, and poorly documented. Here, we assess the potential of COI-based metabarcoding to …

Ultraconserved element-based phylogenomics and siphonal traits illuminate the evolution of tellinoidean clams (Mollusca: Bivalvia: Tellinoidea)

Alan Rodrigo Batistão, Jorge A. Audino, Ella T Frigyik, Lenita de Freitas Tallarico et autres

Abstract Tellinoidea, one of the most diverse superfamilies of Bivalvia, include 954 extant species classified into five families. Although the monophyly of Tellinoidea is well corroborated by morphological and molecular data, the monophyly of the individual families and their relationships remain contentious, …

Soft‐Bottom Bivalves (Mollusca) in an Impacted Brazilian Marine Protected Area and Adjacent Regions

Marcel Sabino Miranda, Luca Castrezana, Fabrizio Marcondes Machado, Lucas Buruaem Moreira et autres

ABSTRACT Bivalves are a key group in benthic assemblages. Besides, little is known about this fauna, especially in marine protected areas (MPAs) from neotropical regions, for example, in Brazil. Here, we provide the results of the taxonomic composition and ecology of bivalve …

At the doors of the Amazonian region: occurrence of Limnoperna fortunei (Dunker, 1857) (Mollusca, Bivalvia, Mytilidae) in the Tocantins River

Rubens Tomio Honda, Igor Christo Miyahira, Flávio Dias Passos

The Tocantins river basin was one of the few regions in Brazil considered free of Golden Mussel, Limnoperna fortunei (Dunker, 1857). This is an invasive species that has been dispersing throughout South America since 1990. We report the first record of this …
