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.

Water Use Behavior of Individual Birds: Ring Ouzels in an Arid High‐Mountain Ecosystem

Integrative Zoology, EarlyView.
Water is a limiting resource for birds in arid ecosystems. Individual birds differ strongly in how they use shared water sources, with drinking behavior increasing with temperature. Behavioral differences, hierarchy, and social context ultimately shape unequal access to water within the population. ABSTRACT Water availability strongly constrains animal

Morphotype Bias, Morph Specific Recruitment and No Elevation‐Life History Relation in High Altitude Mesquite Lizard Populations

Integrative Zoology, EarlyView.
Site‐level differences in population growth (λ) and phenotype frequencies. Mountain silhouettes represent the three study sites. Morph relative abundances are shown in the colored vertical bar. Point estimates and confidence intervals of λ for each site are displayed below, with the dashed line marking the threshold for demographic stability (λ = 1 ...

Parasites at the Summit: Unexpected Geographic Distribution of the Blood Parasite Lineage Found in the Endangered Giant Lizard of Tenerife

Integrative Zoology, EarlyView.
We combined microscopic screening and molecular phylogenetic analyses to characterize blood parasites infecting Gallotia intermedia from the coastal cliffs of Montaña de Guaza and to place these infections in a broader biogeographic context. We detected apicomplexan parasites of the genus Karyolysus infecting 53.6% of G.

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

Small Airways Dysfunction and Remission in Adults With Asthma: A Longitudinal Exploratory Analysis of the AssessmenT of smalL Airways involvemeNT In aSthma (ATLANTIS) Study

Allergy, EarlyView.
We conducted a post hoc analysis of ATLANTIS, a multinational prospective study including 684 adults with asthma. Fewer small airway symptoms and lower disease activity are independently associated with asthma remission. Replicated airway transcriptomic signatures show increased IL‐4/13 signalling and reduced coagulation pathways across the ATLANTIS ...
