Modelling marsupial mastication: The biomechanical bite model of the Linnaeus's mouse opossum Marmosa murina (Marsupialia, Didelphidae)

Journal of Anatomy, EarlyView.
The marsupial masticatory apparatus has rarely been studied until recently, mainly in Australasian species. We therefore reconstructed the maximum bite forces of the South American Linnaeus's mouse opossum Marmosa murina using in vivo bites, specimen dissections, and 3D static equilibrium of the jaw muscles.

New information on Late Triassic sauropodomorph dinosaurs provides support for the independent acquisition of postcranial skeletal pneumaticity in avemetatarsalian lineages

Journal of Anatomy, EarlyView.
PSP in early‐branching sauropodomorphs probably evolved first in the neural arches of the posterior cervical vertebrae, expanding anteriorly and posteriorly along the vertebral column. The distribution of PSP in Late Triassic early‐branching sauropodomorphs does not appear to be correlated with body size.

Exponential increase in the base substitution rate in recent geologic time. ABSTRACT Angiospermae radiation is widely recognized as a mid‐Cretaceous event, but the adaptive radiation of Asarum and Viola as spring ephemerals also occurred during the Quaternary. To better understand the evolution of Angiospermae through geological time, a robust and well‐

A genetic transformation system for the heterotrophic diatom Nitzschia putrida (Bacillariophyceae)

Journal of Phycology, EarlyView.
Abstract Diatoms are important primary producers in aquatic ecosystems. Most of them are photoautotrophs and have evolved to thrive under diverse environmental conditions from the poles to the tropics. However, some diatom species such as Nitzschia putrida have lost photosynthesis and have therefore become free‐living secondary heterotrophs.

Expelled by the Antarctic ice: Evolutionary history of the tribe Cunonieae (Cunoniaceae)

Journal of Systematics and Evolution, EarlyView.
Multiple fossil calibration points reveal recent radiations and biogeographical history of the Cunonieae tribe. The most densely sampled phylogeny allowed to infer Antarctica and Patagonia as areas of origin, confirming the reestablishment of Pterophylla and revealing the northward movement of Weinmannia into the tropical Andes. Conflicting plastid and

Soil phosphate availability drives shifts between arbuscular mycorrhizal and ectomycorrhizal fungi in the dual mycorrhizal plant Quercus serrata

New Phytologist, EarlyView.
Summary Dual mycorrhizal plants are associated with both arbuscular mycorrhizal (AM) and ectomycorrhizal (EcM) fungi that differ in cost and effectiveness for nutrient acquisition. Little is known about environmental drivers for the shifts between these associations in dual mycorrhizal plants.
