Budding speciation, mitochondrial capture and introgression between surface and cave lineages in the Asellus aquaticus species complex

Cladistics, EarlyView.
Abstract Replicated pairs of ancestral and evolutionarily derived populations provide opportunities to test hypotheses about the deterministic laws of evolution. The Asellus aquaticus species complex is an invertebrate model system with several independent surface‐to‐cave transitions and a complicated and unresolved evolutionary history.

Bony fish genomes: Status and gaps

Journal of Fish Biology, EarlyView.
Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

Scratching beneath the surface: Quantification of muscle architecture and myosin heavy chain content in the forelimbs of black‐tailed prairie dogs (Cynomys, Rodentia)

Journal of Anatomy, EarlyView.
Black‐tailed prairie dogs are highly social ground squirrels that excavate communal burrow systems, most often in medium‐textured soils. Their forelimbs demonstrate morphofunctional trade‐offs for scratch‐digging and terrestrial ecology, including well‐developed and fast‐contracting proximal musculature with large mechanical advantage paired with ...

Effect of metal framework design on the fracture resistance of implant‐supported metal–ceramic crowns fabricated by selective laser melting

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the fracture resistance of implant‐supported metal–ceramic crowns fabricated using selective laser melting (SLM), according to the metal support height around the screw access hole (SAH) and the substructure design. Materials and Methods Metal–ceramic crowns and rectangular bilayer specimens were fabricated using SLM in two

Preparation and Properties of Microarc Oxidation Self-Lubricating Composite Coatings on Aluminum Alloy

Metals, 2017
Microarc oxidation (MAO) coatings were prepared on 2024-T4 aluminum alloy using pulsed bipolar power supply at different cathode current densities. The MAO ceramic coatings contained many crater-like micropores and a small number of microcracks.

Description of Flavicapitulum gen. nov. and two new species of Marmoreocelis from thermal habitats in the Americas

Journal of Phycology, EarlyView.
Abstract Three novel taxa in the Coleofasciculales were observed in hot springs in Yellowstone National Park, Wyoming, United States, and in the Tabaconcito thermal springs on the Rio Tabacón in Costa Rica. Flavicapitulum vaporiphilum gen. et sp. nov. was located in a supported clade with Gracilinea and Marmoreocelis.

Emerging risk factors influencing the occurrence of peri‐implantitis

Periodontology 2000, EarlyView.
Abstract Background The objective of the present review is to explore the evidence and biological plausibility of factors that may expose dental implants to a greater likelihood of developing peri‐implantitis. Material and Methods An electronic screening on the PubMed library the was carried out to identify potential emerging factors that influence the
