ABSTRACT This study examines faunal assemblages from paired semisubterranean houses and middens at 10 Early Inuit sites spanning the North American Arctic (ca. 1200–1500 ce) to evaluate whether local resource bases or other factors primarily structure zooarchaeological variability.

The genetic architecture of leaf vein density and its importance for photosynthesis in maize
Vein types in maize leaves. Summary Leaf venation density has significantly increased during plant evolution. Higher densities are observed in angiosperms compared with early land plants, and among angiosperms, recently diverged C4 species have the highest values.

The study focusses on the morphological evolution of worldwide restored intertidal flats. These intertidal flats initially experience high sedimentation rates after the opening of the connection with open waters. The anthropogenic structures cause high morphological instability and are eroded, leading to a self‐cannibalisation of the system.

Abstract As climate change is having increasingly visible impacts on coastal regions, it is urgent to better understand its effects on the state of ecosystems and the services they provide. To assess the direction and magnitude of change in the high‐use waters of the Sept‐Îles region in the Gulf of St‐Lawrence, we sampled 35 sites along the coast and ...

New Approach to Unsymmetric Curcuminoids and Their BF2‐derivatized Fluorophores
The synthesis of asymmetric curcuminoids can be successfully achieved through a ketal intermediate, which is then condensed with one aldehyde, followed by hydrolysis and complexation with BF3·THF. Further condensation with a different aldehyde produces an asymmetric BF2‐curcuminoid derivative.
