The Anatomical Record, Volume 309, Issue 7, Page 1702-1712, July 2026.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

Limnology and Oceanography, Volume 71, Issue 7, July 2026.Abstract Oxygen is critical for nearly all life on Earth, including aquatic species that breathe dissolved oxygen in both freshwater and marine systems. The rapid, global, and anthropogenic loss of dissolved oxygen known as “aquatic deoxygenation” threatens life in these environments, the human communities that depend on them, and Earth system ...

Reproduction and Development in Calcareous Sponges: A Panorama of the Last Two Centuries
Molecular Reproduction and Development, Volume 93, Issue 7, July 2026.ABSTRACT Nearly 200 years ago, scientists began examining reproductive cells in calcareous sponges (Calcarea, Porifera). Since then, 238 studies have been published, encompassing descriptions of gametes and embryos (including ultrastructural studies), life history, asexual reproduction, regeneration, and molecular aspects of development.

Connecting the distribution and diversification of marine plants
Oikos, Volume 2026, Issue 7, July 2026.Integration of the evolutionary history with distribution of extant species is necessary to explain present‐day diversity, particularly for ‘foundation' species, such as seagrasses, which create habitats of socioecological relevance. Here, we resolved if varying evolutionary history of seagrass families has imprinted the distribution ranges of extant ...

L2 fossilization: a competence or a performance phenomenon
The study reported here examined the question whether fossilization occurs as a result of competence deficiencies or is a function of processing constraints, i.e., a feature of performance.

The Structure and Lifecycle of Stratified Mixing by Shear Instabilities in Continuously Forced Flows
Journal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.Abstract The turbulent energy cascade of ocean mixing remains poorly understood at geophysically large Reynolds numbers (Re $\mathrm{R}\mathrm{e}$). Here we propose a new conceptual model for the structure of small‐scale mixing grounded in high‐resolution multibeam echosounding observations from the mouth of the Connecticut River, a shallow salt‐wedge ...
