Conservation implications of low contemporary connectivity along the Mid‐Atlantic Ridge in hydrothermal vent gastropods

Conservation Biology, EarlyView.
Abstract Polymetallic sulfide deposits produced at hydrothermal vent fields are targets for mining exploitation along the Mid‐Atlantic Ridge, threatening the functioning and resilience of vent ecosystems that provide multiple ecosystem services. Knowledge about connectivity between vents will inform conservation practices.

Orchid genome evolution and trait innovation

Journal of Integrative Plant Biology, EarlyView.
Orchids became one of the world's most diverse plant groups through genome‐driven innovations, unique relationships with fungi and pollinators, and remarkable adaptability. This review explains the origins of orchids and the evolution of their distinctive life forms, flowers, and ecological strategies and highlights promising directions for future ...

First occurrences of Trionychidae (Testudines, Cryptodira) from the Miocene of Poland: Detailed cranial anatomy and biogeographic implications

Journal of Anatomy, EarlyView.
Fossil finds from three Middle Miocene sites in Poland reveal the northernmost known presence of trionychid turtles in Europe, tentatively identified as Trionyx cf. vindobonensis, suggesting a warmer climate that supported thermophilic species in Central Europe during this period. Abstract Modern trionychids (Testudines, Cryptodira) have a pan‐tropical

Orchestrated molecular changes of proliferative, migratory‐fibrillar, synaptic, and postmigratory compartments align with precocious cortex‐type specification in the early human pallium

Journal of Anatomy, EarlyView.
Early human cortical development is organized by transient cellular compartments that define cortical types before mature layers form. Analysis of the human fetal pallium (7.5–15 PCW) shows distinct spatiotemporal trajectories for the archicortex, mesocortex, and neocortex, with delayed but accelerated differentiation in allocortical regions.

1D Basin Modelling of Upper Jurassic to Upper Cretaceous Source Rocks in the Southern Pletmos Sub‐Basin, Outeniqua Basin, Offshore South Africa

Journal of Petroleum Geology, EarlyView.
ABSTRACT The Pletmos sub‐basin in the Outeniqua Basin, offshore South Africa, is divided by the Superior, Pletmos and Plettenberg faults into northern and southern depocentres. In this study, geological and organic geochemical data together with 1D basin modelling were used to investigate the burial, thermal and maturation histories, and the timing of ...

Polymict melt‐bearing breccia dikes in the Morokweng impact structure formed by slip‐induced mechanical mixing of pseudotachylite and cataclasite along large‐displacement impact faults

Meteoritics &Planetary Science, EarlyView.
Abstract A core drilled through shocked and faulted Archean granitoid gneisses and dolerites in the eroded peak ring of the 70–80 km diameter Morokweng impact structure intersects multiple centimeter‐ to meter‐wide clastic‐matrix breccias containing a polymict clast population of lithic and mineral clasts and altered, millimeter‐ to centimeter ‐size ...

Small‐scale adaptation to geothermal soil heating in a perennial herb revealed by combining crosses and transplantations

New Phytologist, EarlyView.
Path diagrams showing the results of piecewise structural equation models examining how fitness (total number of seeds in flowering individuals) of Cerastium fontanum depended on temperature at planting site, temperature difference, mating type, and flowering time (FFD, first flowering date) in each of the two study years.

Spherulite in the modern aragonitic travertine stromatolite has a calcite core with exopolymers

Sedimentology, EarlyView.
ABSTRACT Spherulites are spherical to ellipsoidal particles formed by various crystalline substances and can be abiotically synthesised in the laboratory. Among various spherulite types, spherulites composed of calcium carbonate are also found in various natural environments, but their abiotic or biotic origins are still controversial.
