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 ...

Transcriptomics Unveil Dsx1 as a Critical Regulator in Sexual Dimorphism of Crustaceans

Integrative Zoology, EarlyView.
Sexually dimorphic traits are involved in reproductive competition and are shaped by sex‐biased gene expression. This study identifies Dsx1 as a key male‐biased gene in Morinoia aosen and demonstrates through RNA interference that its disruption feminizes male‐specific T3 leg structures.

Pseudonyms, Propaganda, and Prints: The Life and Political Caricatures of William Dent, 1782–931

Journal for Eighteenth-Century Studies, EarlyView.
Abstract ‘Dent was probably an amateur and nothing is known of his life’, state Bryant and Heneage. Despite contributing to caricature's ‘golden age’, William Dent remains overlooked compared to contemporaries like James Gillray. Dent's extensive portfolio (1782–93) and rumoured role as a Pittite propagandist have not secured his place in the canon of ...

Using wingbeat frequency to estimate mass gain

Methods in Ecology and Evolution, EarlyView.
Abstract Energy intake is a fundamental currency in ecology that is critical to reproductive success, survival and lifetime fitness. Measuring foraging success in wild animals via biologgers has been a long‐standing challenge but is essential to understanding the mechanisms underlying population dynamics and species distributions.
