Mineralized area of the human rib cross‐sections from early puberty until adulthood
The Anatomical Record, EarlyView.Abstract Ribs undergo numerous changes during growth and development. Although they occur both externally and internally, the latter are not as extensively documented during the transition from puberty to adulthood. Therefore, it is unknown how rib cross‐sectional mineralized area changes during this period.

The Anatomical Record, EarlyView.Abstract Actinopterygii is a major extant vertebrate group, but limited data are available for its earliest members. Here we investigate the morphology of Devonian actinopterygians, focusing on the lower jaw. We use X‐ray computed tomography (XCT) to provide comprehensive descriptions of the mandibles of 19 species, which span the whole of the Devonian

Commentary: What's so interesting about sabertooths?
The Anatomical Record, EarlyView.Abstract Sabertooth creatures are fascinating to the public and to scientists. This Special Issue on The Anatomy of Sabertooths starts with a discussion of what exactly a sabertooth is, continues with a couple of papers about other animals with extraordinarily long teeth, and then delves into analyses of fossil sabertoothed taxa—some of which are not ...

Detecting patterns of species diversification in the presence of both rate shifts and mass extinctions [PDF]
, 2015 Recent methodological advances are enabling better examination of speciation and extinction processes and patterns. A major open question is the origin of large discrepancies in species number between groups of the same age.

Developmental Dynamics, EarlyView.Abstract Background Jointed appendages represent one of the key innovations of arthropods, and thus understanding the development and evolution of these structures is important for the understanding of the evolutionary success of Arthropoda. In this paper, we analyze a cell cluster that was identified in a previous single‐cell sequencing (SCS ...

Lethaia, EarlyView., 2021 Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

Elongated theropod tracks from the Cretaceous Apenninic Carbonate Platform of southern Latium (central Italy) [PDF]
, 2015 New dinosaur footprints were recently discovered in southern Latium (Italy). The tracks all appear slightly differently preserved and are characterized by elongated metatarsal impressions, recording the complex locomotor behaviour of a medium-sized ...

The division of food space among mammalian species on biomes
Ecography, EarlyView.Understanding how species' ecological partitioning functions across biomes is fundamental to macroecology and conservation biology. Here, we examine the global distribution of dietary strategies in terrestrial mammals, focusing on how biome specialization modulates trophic diversity and structure at a broad geographical scale.

Shared patterns in body size declines among crinoids during the Palaeozoic extinction events
Scientific Reports, 2021 Crinoids were among the most abundant marine benthic animals throughout the Palaeozoic, but their body size evolution has received little attention. Here, we compiled a comprehensive database on crinoid calyx biovolumes throughout the Palaeozoic. A model

Geological Journal, EarlyView.ABSTRACT This research intends to examine how renewable energy (REN) consumption and natural resource (RES) rents affect the environmental impact of consumption in Switzerland. Along with REN and RES, the study considers Information and Communication Technology (ICT) and participatory democracy as other independent variables of interest.
