An enigmatic crocodyliform tooth from the bauxites of western Hungary suggests hidden mesoeucrocodylian diversity in the Early Cretaceous European archipelago [PDF]

open access: yes, 2015
Background. The Cretaceous of southern Europe was characterized by an archipelago setting with faunas of mixed composition of endemic, Laurasian and Gondwanan elements. However, little is known about the relative timing of these faunal influences.

Phylogenomics and phylogeographic model testing using convolutional neural networks reveal a history of recent admixture in the Canarian Kleinia neriifolia

open access: yesMolecular Ecology, Volume 33, Issue 21, November 2024.
Abstract Multiple‐island endemics (MIE) are considered ideal natural subjects to study patterns of island colonization that involve recent population‐level genetic processes. Kleinia neriifolia is a Canarian MIE widespread across the archipelago, which exhibits a close phylogenetic relationship with species in northwest Africa and at the other side of ...

Population Genomics of Adaptive Radiations: Exceptionally High Levels of Genetic Diversity and Recombination in an Endemic Spider From the Canary Islands

open access: yesMolecular Ecology, Volume 33, Issue 22, November 2024.
ABSTRACT The spider genus Dysdera has undergone a remarkable diversification in the oceanic archipelago of the Canary Islands, with ~60 endemic species having originated during the 20 million years since the origin of the archipelago. This evolutionary radiation has been accompanied by substantial dietary shifts, often characterised by phenotypic ...

Cryptic Diversity of Mediterranean Neogoniolithon (Corallinales, Corallinophycidae, Rhodophyta)

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 10, October 2024.
ABSTRACT Neogoniolithon is a widespread genus of non‐geniculate coralline algae in the Mediterranean Sea. Three vaguely differentiated species have been reported in the region. This study examined the diversity of Neogoniolithon in the Mediterranean by inferring phylogenies using psbA and COI‐5P markers, applying delimitation algorithms and comparing ...

On the origin of Halipeurus heraldicus on Round Island petrels: cophylogenetic relationships between petrels and their chewing lice [PDF]

open access: yes, 2010
Lice phylogenetic relationships have often been used to elucidate host relationships and vice versa. In this study, we investigate the louse genus Halipeurus which parasitizes bird hosts in the families Procellariidae, Hydrobatidae and Pelecanoididae ...
