Comparative and functional anatomy of masticatory muscles and bite force in opossums (Didelphimorphia, Didelphidae)

open access: yesThe Anatomical Record, EarlyView.
We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...

Nuclear structure and symmetry evolution in 190,192 84Po: insights from IBM-1, VMI, and GVMI [PDF]

open access: yesЯдерна фізика та енергетика
In this study, three nuclear models - the Interacting Boson Model-1 (IBM-1), the Variable Moment of Inertia (VMI), and its generalized form (Generalized Variable Moment of Inertia - GVMI) - were employed to investigate the low-lying collective states of ...

Inside a duck‐billed dinosaur: Vertebral bone microstructure of Huallasaurus (Hadrosauridae), Upper Cretaceous of Patagonia

open access: yesThe Anatomical Record, EarlyView.
Abstract Dinosaurs evolved a unique respiratory system with air sacs that contributed to their evolutionary success. Postcranial skeletal pneumaticity (PSP) has been used to infer the presence of air sac systems in some fossil archosaurs. While unambiguous evidence of PSP is well documented in pterosaurs and post‐Carnian saurischians, it remains absent

Indication of Ecological Condition of the Black Sea Mussels and Their Habitat Using Natural Radionuclide Polonium-210 [PDF]

open access: yesЖурнал Сибирского федерального университета: Серия Биология, 2017
Accumulation of polonium-210 by the Black Sea mussels in Sevastopol marine region and the Karadag Bay (the eastern part of the coast of the Crimea) depends on the mass of their soft tissue, sex, stage of gonad development and the conditions of their ...

Revisiting a long‐overlooked skull: Implications for the distribution of Dinodontosaurus brevirostris (Kannemeyeriiformes) in the Brazilian Triassic

open access: yesThe Anatomical Record, EarlyView.
Abstract Dicynodonts (Anomodontia: Dicynodontia) were one of the main groups of terrestrial tetrapods in Permian and Triassic faunas. In Brazil, the genus Dinodontosaurus is one of the most common tetrapod taxon in the Triassic Santa Maria Supersequence. This genus has a complex taxonomic history and is represented in the Triassic of both Argentina and

A study on the transition between seniority-type and collective excitations in 204Po and 206Po

open access: yesEPJ Web of Conferences, 2018
Low-lying yrast states in 204Po and 206Po have been investigated by the γ-γ fast timing technique with LaBr3(Ce) detectors. Excited states of these nuclei were populated in the 197Au(11B,4n) and the 198Pt(12C,4n) fusion-evaporation reactions ...

The coelurosaur theropods of the Romualdo formation, early Cretaceous (Aptian) of Brazil: Santanaraptor placidus meets Mirischia asymmetrica

open access: yesThe Anatomical Record, EarlyView.
Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.
