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

open access: yesIntegrative 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 ...

Metabolome Diversity Enhances Resistance of Intertidal Clams to Thermal Stress

open access: yesIntegrative Zoology, EarlyView.
Meretrix species are widely distributed intertidal bivalves in China with significant ecological and economic importance, which are sensitive to thermal stress. Our results showed that thermal environments of clam habitats shaped metabolome diversity, which can enhance the resistance of intertidal clams to thermal stress.

Osteological, Biological, and Genetic Consequences of Colonization of Fresh Waters by Marine Cottoid Fishes (Cottidae)

open access: yesIntegrative Zoology, EarlyView.
Lacustrine forms of Triglopsis from North American and European lakes are at different stages of evolution, making them a suitable model for testing hypotheses about evolutionary patterns and rates. An integrative analysis of morphological, genetic, and biological adaptations occurring in lacustrine forms of the genus Triglopsis was carried out.
