Intraspecific variation of cochlear morphology in bowhead and beluga whales
The Anatomical Record, EarlyView.Abstract The bony labyrinth of the petrosal bone, a distinctive feature of mammal skulls, is often identified in micro‐computed tomography imaging to infer species' physiological and ecological traits. When done as part of a comparative study, one individual specimen is normally considered representative of a species, and intraspecific variation is ...

The Depositional Record, EarlyView.A new classification for inland freshwater palaeowetlands to be used in the field or core laboratory by sedimentologists, providing examples from the Guadix Basin (southern Spain). Abstract Present wetlands have proven to be delicate, biodiverse ecosystems, that are natural sinks for CO2 and act as good indicators for climate changes.

Water pathways and ancient lakes: Flowing towards new models to unravel the past
The Depositional Record, EarlyView.Abstract Significant progress has been made in understanding lake basin evolution through climatic and tectonic changes using sedimentology, sequence stratigraphy, geochemistry, hydrology and watershed characteristics to interpret three main lake basin types: overfilled, balanced‐fill and underfilled, including fluvio‐lacustrine systems.

The Depositional Record, EarlyView.A 30 m long sedimentary succession at the bottom of the Belize Blue Hole represents terrestrial cenote (12.5–7.2 ka BP), restricted marine swamp (7.2–5.7 ka BP) and fully marine lagoonal phases (5.7–0 ka BP) on Lighthouse Reef carbonate platform. Post‐glacial and Holocene sea‐level rise largely controlled the sedimentological, faunal and floral changes

Philosophy, Theory, and Practice in BiologyExisting accounts of data are unclear about whether the epistemic role objects play makes them data, or whether data have to be produced by human interaction with the world – these two features can come apart.

The Depositional Record, EarlyView.The Bisperode section is one of the most expanded and complete sections with shallow‐marine Oxfordian strata in the LSB. This study provides a reference record for shallow‐marine settings and allows for the correlation of the strata from the LSB with Oxfordian deposits distributed elsewhere in the world.
