Clues of ancient incomplete lineage sorting during bivalve evolution undermine support for Heterodonta

Cladistics, EarlyView.
Abstract A long‐standing challenge in phylogenomics has been the resolution of relationships originated from ancient radiations. In these cases, phenomena such as incomplete lineage sorting can increase the support for conflicting resolutions. Most of the diversity in the Class Bivalvia originated during an Ordovician radiation; indeed, several deep ...

Genealogical approaches to the temporal origins of the Central American gap: Speciation and divergence in Pacific Chthamalus (Sessilia: Chthamalidae)

Revista de Biología Tropical, 2013
A large section of the tropical Eastern Pacific coastline is nearly devoid of reef or consolidated habitat, and is known as the Central American Gap as it is associated with a biogeographic transition in fish and invertebrate species.

A revised classification system of the marronoid clade of spiders (Araneae), based on dense sampling phylogenomics and comparative morphology

Cladistics, EarlyView.
Abstract The marronoid clade is a globally distributed, ecologically diverse group of spiders. It is an important faunal component in both natural and synanthropic environments, and even found in aquatic and extreme habitats such as desert salt flats. The systematics of the marronoid clade has been notoriously unstable due to the widespread character ...

When and why to give shorebirds a head start

Conservation Biology, EarlyView.
Abstract Headstarting is a translocation technique involving the hatching or rearing of wild eggs or young in captivity and the release of those individuals back to the wild at or before independence. It has been trialed as a conservation intervention for shorebirds over recent decades to improve the population trend of target populations by increasing

New records and five new species of sipunculans (Sipuncula) from the central and northwestern Mexican Pacific

European Journal of Taxonomy
Sipuncula are marine unsegmented worms that can be found in benthic habitats, from shallow to deep-sea waters. In Mexico these worms have been scarcely studied.

Extreme site fidelity in long‐distance migratory shorebirds in Australia and potential implications for conservation

Conservation Biology, EarlyView.
Abstract Site fidelity is the tendency for animals to repeatedly return to the same locations, either within or between years. Site fidelity enables animals to utilize knowledge of previously visited locations, including assessments of seasonal variations in health and mortality risks (e.g., predation), resource availability, and social benefits such ...
