Coral Recovery in the Central Mexican Pacific 20 Years after the 1997–1998 El Niño Event

open access: yesOceans, 2022
El Niño–Southern Oscillation (ENSO) events are increasing globally in both frequency and strength, and they can elicit coral bleaching events. The 1997–1998 ENSO caused mass coral mortality with a 96% decline in live coral cover along the Central Mexican

A new, conspicuously pigmented Pyrrhulina (Teleostei: Characiformes: Lebiasinidae) from the Río Tigre, Loreto, Peru

open access: yesJournal of Fish Biology, EarlyView.
Abstract A new species of Pyrrhulina is described based on morphological and molecular evidence. Pyrrhulina punctata is distinguished from all congeners by the presence of a series of 7 to 16 irregular blotches of dark pigmentation on the flanks, equally marked in juveniles and adult specimens, the presence of 26–28 lateral‐line scales, 17–21 maxillary

Patterns of Interploidy Admixture in Polyploid Complexes: Insights From Thymus Sect. Mastichina (Lamiaceae)

open access: yesMolecular Ecology, Volume 35, Issue 3, February 2026.
ABSTRACT Understanding gene flow between ploidy levels in polyploid complexes is essential for species delimitation and conservation. This study explores evolutionary dynamics in the polyploid complex Thymus sect. Mastichina (Lamiaceae), comprising three taxa: T. mastichina subsp. mastichina, T. mastichina subsp.

Daimophyllon gen. nov., a striking new genus of Athetini rove beetle (Coleoptera: Staphylinidae) from Brazil with description of two new species

open access: yesAustral Entomology, Volume 64, Issue 4, November 2025.
Abstract Among the Aleocharinae rove beetles, the tribe Athetini is one of the most diverse and morphologically poorly delimited, obviously non‐monophyletic groups, with approximately 4000 described species. Despite overlapping morphological diagnoses of Athetini and other tribes such as Oxypodini, as well as many poorly delimited genera in Athetini ...

A Long‐Standing Taxonomic Puzzle: Species Delimitation and Phylogenetic Analysis Reveal New Findings in Neogoniolithon (Spongitidaceae, Corallinophycidae and Rhodophyta) From the Southwestern Atlantic

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 10, October 2025.
ABSTRACT In the first study on Neogoniolithon species for the Southwestern Atlantic Ocean, based on both molecular (COI‐5P, psbA and SSU rDNA) and morpho‐anatomical data, three taxa were identified for the Brazilian coast, including two new species. DNA‐based species delimitation methods distinguished Neogoniolithon crypticum sp. nov.
