The Earliest Feathers from the Lower Cretaceous Dabeigou Formation of North Hebei: Implications for the Early Evolution of the Jehol Biota

Integrative Zoology, EarlyView.
This study reports two isolated feather fossils from the Lower Cretaceous Dabeigou Formation in northeastern China. Morphological analyses identified them as the earliest known feathered theropods (potentially including avian) in the Jehol Biota. This finding reveals a complex ecosystem at the dawn of the Jehol Biota, bridging the temporal and faunal ...

Host desiccation and interspecific competition limit reproductive performance of a bark beetle

Agricultural and Forest Entomology, EarlyView.
At high and moderate phloem moisture levels, Polygraphus proximus reproductive success was suppressed by sympatric species density. At low phloem moisture, P. proximus reproductive success was suppressed by the low phloem moisture regardless of the Cryphalus laricis hole density. Conspecific density (i.e., attack density of P.
