Effects of Vector Density on Blood Parasite Spread and Health Consequences for Avian Hosts: An Experimental Epidemiology Blueprint

open access: yesIntegrative Zoology, EarlyView.
In an experimental epidemiology setup, groups of pigeons were exposed to different numbers of infective malaria vectors. Vector number explained the speed of transmission, the final prevalence, and changes in host behavior. ABSTRACT Vector density plays a critical role in the transmission dynamics of vector‐borne diseases and thus in their health and ...

Unraveling Occurrence Patterns and Diversity of Avian Malaria Parasites in Iberian Obligate and Facultative Scavenger Birds

open access: yesIntegrative Zoology, EarlyView.
Low overall haemosporidian occurrence (3.4%; 13/383). Unexpected high lineage diversity (10 new host–parasite interactions). Novel Leucocytozoon lineage (GYPBAR01) in all European vultures except the griffon vulture. Plasmodium relictum (lineage SGS1) in adult red kites.

Beyond Sexual Selection: Natural Selection Related Camouflage and Thermoregulation Shape Sexual Color Dimorphism in Diploderma Lizards

open access: yesIntegrative Zoology, EarlyView.
Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...

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 ...

Platinum Group Element Traces of CAMP Volcanism Associated With Low‐Latitude Environmental and Biological Disruptions

open access: yesGeophysical Monograph Series, Page 263-304., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

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

open access: yesIntegrative 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.
