Reduced fitness cost accounts for the stability of a malathion‐resistant heterogeneous duplication haplotype in Ceratitis capitata field populations

Pest Management Science, EarlyView.
Malathion resistance in Spanish field populations of Ceratitis capitata is associated with a point mutation (R allele) and a heterogeneous duplication (RS haplotype) of the Ccace2 gene. The R allele imposes a higher fitness cost than the RS haplotype under laboratory and field conditions. An evolutionary model supports the stability of the RS haplotype

Pesticides and Hypospadias in Southern Brazil: An Ecological Study

Environmental Toxicology, EarlyView.
ABSTRACT Rio Grande do Sul ranks among the Brazilian states with the highest pesticide consumption and one of the highest prevalences of hypospadias, a congenital anomaly often associated with prenatal exposure to endocrine‐disrupting chemicals. We assessed the relationship between prenatal pesticide exposure and hypospadias risk through an ecological ...

Identifying functionally relevant candidate genes for inflexible ethanol intake in mice and humans using a guilt‐by‐association approach

Brain and Behavior, 2020
Gene prioritization approaches are useful tools to explore and select candidate genes in transcriptome studies. Knowing the importance of processes such as neuronal activity, intracellular signal transduction, and synapse plasticity to the development ...

Comparative Satellitomics in Arowanas (Telostei, Osteoglossiformes) Sheds Light on the Evolution of Ancient Satellite DNAs

Integrative Zoology, EarlyView.
This work focused on arowana fishes (Teleostei, Osteoglossiformes) as a model; their widespread intercontinental distribution and basal phylogenetic position within Teleostei make them a compelling model for evolutionary research, especially in the realm of satDNA molecular evolution. Through the integration of genomic and chromosomal data, we analyzed

Population dynamics of potentially harmful haplotypes: a pedigree analysis

BMC Genomics
Background The identification of low-frequency haplotypes, never observed in homozygous state in a population, is considered informative on the presence of potentially harmful alleles (candidate alleles), putatively involved in inbreeding depression ...

Hybridization With a Non‐Native Congener Threatens the Catalan Chub (Squalius laietanus): Optimization of a DNA‐Based Early Warning Tool

Integrative Zoology, EarlyView.
Hybridization with non‐native congeners threatens endemic freshwater fishes. Using a rapid and cost‐effective nuclear DNA assay, we detected widespread hybridization between the Catalan chub (Squalius laietanus) and the non‐native European chub (Squalius cephalus) across S.
