Heritability of Productive, Reproductive and Carcass Traits in Pure‐Bred and Cross‐Bred Pigs: A Systematic Review and Meta‐Analysis

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Heritability (h2) is a key parameter in animal breeding, but its magnitude and consistency across pure‐bred (PB) and cross‐bred (CB) pig populations remain poorly understood. This study aimed to compare heritability estimates between PB and CB populations for economically relevant traits through a systematic review and meta‐analysis.

Cryptic diversity and recent diversification in the Pyrrhulina australis species complex (Characiformes, Lebiasinidae) revealed by mitochondrial DNA

Journal of Fish Biology, EarlyView.
Abstract Pyrrhulina australis Eigenmann & Kennedy, 1903, is widely distributed across the main hydrographic basins of South America. The taxonomic integrity of this species is nevertheless challenged by the lack of clear diagnostic characters, its marked geographic variation and the morphological overlap with its congeners. In this context, the present

Tick‐borne diseases in subtropical dairy farming: The role of calf rearing strategies in antibody and antigen prevalence Enfermedades Transmitidas por Garrapatas en la Ganadería Lechera subtropical: El Papel de las Estrategias de Crianza de Terneros en la Prevalencia de Anticuerpos y Antígenos

Medical and Veterinary Entomology, EarlyView.
Tropical farmers try to adapt calf‐rearing systems to temperate dairy industry standards. Calves in tick‐infested areas develop stronger immunity to TBD under controlled exposure to ticks. Early tick exposure promotes sustainable management, balancing tick infestation and developing TBD immunity.

Urban ants as potential mechanical vectors of pathogenic and antibiotic‐resistant bacteria in a Brazilian hospital

Medical and Veterinary Entomology, EarlyView.
Nine ant taxa were identified in a Brazilian hospital, with Tapinoma melanocephalum and Dorymyrmex brunneus being the most abundant. Eighty‐five percent of collected ants yielded detectable bacterial growth, including clinically relevant genera such as Acinetobacter, Pseudomonas, Escherichia coli and Pluralibacter.

microRNA‐mediated control of cell fate specification and patterning in Marchantia polymorpha

New Phytologist, EarlyView.
The gemma developmental program in Marchantia polymorpha is coordinated by MpMIR166‐mediated repression of MpC3HDZ and auxin homeostasis. Summary MicroRNAs (miRNAs) are small non‐coding RNA molecules essential for growth and development in eukaryotes. In plants, the master gene DICER‐LIKE 1 (DCL1) catalyzes the biogenesis of miRNAs by processing double‐
