Beyond first clutches: Second broods reshape selection on breeding timing in forest and urban great tits

Journal of Animal Ecology, EarlyView.
Most studies of selection on breeding timing consider only first clutches. Using a 13‐year dataset of urban and forest great tits, we show that including second broods reshapes estimates of natural selection, revealing that early breeding is favoured through increased probability of multiple brooding and higher annual reproductive output.

Comparative Analysis of the Gut Microbiota of Thai Indigenous Chicken Fed House Crickets

Animals
The gut microbiota is pivotal to chickens’ overall health, influencing digestion, nutrient absorption, and immune function. Dietary compounds significantly impact gut microbiota composition.

Environmental factors associated with nesting habits and age shape the composition and connection between skin and uropygial gland microbiomes of birds

Journal of Animal Ecology, EarlyView.
This study provides new insights into how ecological conditions influence the evolution of host‐associated symbiotic communities and their functional roles. The findings suggest that pathogen pressures linked to nesting habits in birds shape bacterial communities of the uropygial gland, and their connection with the skin microbiome, where the ...

Museomics Deciphers the Phylogeographic Differentiation and Conservation Status of a Montane Pheasant

Integrative Zoology, EarlyView.
Museum specimens provide a rich source of historical DNA, enabling insights into phylogenetic relationships and demographic history of the endangered Koklass Pheasant. Our findings uncovered a previously unrecognized population in Guizhou province and highlighted elevated extinction risk in populations from Anhui province and Southern China, informing ...

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

Integrative 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

Integrative 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 ...

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.
