Tooth morphology of deep‐water catsharks of the genus Apristurus (Chondrichthyes: Pentanchidae) in the North Atlantic Ocean

open access: yesJournal of Fish Biology, EarlyView.
Abstract The deep‐water catshark family (Pentanchidae) is the most species‐rich family among extant shark lineages. Within this family, the genus Apristurus is the largest, comprising small, deep‐sea species characterised by elongated bodies and dorso‐ventrally compressed snouts. Five Apristurus species are currently recognised from the North Atlantic,

Cryptic diversity and recent diversification in the Pyrrhulina australis species complex (Characiformes, Lebiasinidae) revealed by mitochondrial DNA

open access: yesJournal of Fish Biology, EarlyView.
Abstract Pyrrhulina australis Eigenmann & Kennedy, 1903, is widely distributed across the main hydrographic basins of South America. The taxonomic integrity of this species is nevertheless challenged by the lack of clear diagnostic characters, its marked geographic variation and the morphological overlap with its congeners. In this context, the present

Taxonomic inflation in fish systematics: A critical review with illustrative evidence assessment and integrative case study of the Salmo trutta Complex

open access: yesJournal of Fish Biology, EarlyView.
Abstract Fish species are being described at an accelerating rate, but a substantial fraction of recent descriptions rests on evidentiary standards too weak to distinguish genuine species‐level discontinuities from intraspecific variation, local adaptation and the artefacts of single‐marker analyses, a pattern of taxonomic inflation with documented ...

Orchid genome evolution and trait innovation

open access: yesJournal of Integrative Plant Biology, EarlyView.
Orchids became one of the world's most diverse plant groups through genome‐driven innovations, unique relationships with fungi and pollinators, and remarkable adaptability. This review explains the origins of orchids and the evolution of their distinctive life forms, flowers, and ecological strategies and highlights promising directions for future ...
