Divergent trajectories of genome architecture and chromosome evolution in ferns and angiosperms
Variation in key fern genomic traits across families, mapped onto a summary phylogenetic tree. Summary Ferns and angiosperms represent the two largest vascular plant lineages but exhibit striking genomic and ecological contrasts. We investigated whether differences in genome size, chromosome architecture, GC content, and stomatal traits reveal ...

‘Chrystalline Talk’: Thomas Browne's Poetics of Concretion and Mineral Plain Style
ABSTRACT This article charts the figuration, both material and rhetorical, of mineral bodies in early modern natural philosophy, paying particular attention to the second book of Thomas Browne's Pseudodoxia Epidemica (1646). It argues that concretions (stony calculi and crystals formed through the aggregation of physical matter) make manifest a mineral

ABSTRACT Filamentous, anastomosing spar‐filled networks in Phanerozoic carbonates have been interpreted as the mineralised remains of keratose (non‐spiculate) sponges, yet their recognition remains contested because fabrics of broadly similar appearance may arise from microbial, diagenetic or physical processes. This study combines direct fossil–modern

ABSTRACT Previous studies have documented genetic divergence within the last few million years between northern and southern populations of terrestrial plants and animals along the Baja California peninsula, with many studies hypothesising that the divergence is due to an ancient seaway that crossed the central peninsula and created a physical barrier ...

Impacted Bones: Can Extant Primates Help Identify Tool Use in Early Hominins?
ABSTRACT Despite recent advances pushing back the earliest record of tool use, how and when it first emerged in hominins, and the extent to which it featured amongst the numerous co‐existing species, remain critical questions in paleoanthropology. In addition to analyzing fossils and lithic toolkits, novel strides in understanding this might be made by

ABSTRACT Existential constructions (ECs) play an important role in academic writing by introducing new information, expressing epistemic stance and facilitating information flow. Examining how EFL learners use different EC types can offer valuable insights into their syntactic development and writing proficiency. Previous research, however, has focused

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade
ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

Slope and sediment size in the development of pebble and cobble beaches with low permeability
We studied beaches composed of coarse‐grained beaches. In spite that the occurrence of an impermeable layer at a low depth that reduces its permeability, the correlation between the beach slope and the sediment size corresponds to what was expected, and the underlying and cohesive sediment reached the same slope of the beach.
