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

Rapid evolution and genetic basis of spinetoram resistance in Phthorimaea absoluta: evidence from six years of monitoring and laboratory selection

Pest Management Science, EarlyView.
Resistance to spinetoram in Phthorimaea absoluta is rapidly selected and functionally recessive at field‐relevant concentrations. Metabolic detoxification contributes partially, while cross‐resistance to spinosad and increased susceptibility to diamides and isoxazolines highlight practical options for resistance monitoring and insecticide rotation ...

Evaluation of systemic consequences of brachycephalic obstructive airway syndrome in dogs

Veterinary Record, EarlyView.
Abstract Background Brachycephalic obstructive airway syndrome (BOAS) results from upper airway anatomical abnormalities and may cause systemic effects depending on severity. Methods A prospective, case‒control and observational study was conducted.

Handling mean–variance scaling in intraspecific trait variability and implications for trait–environment analyses

Methods in Ecology and Evolution, EarlyView.
Abstract Trait‐based ecology increasingly relies on measures of intraspecific trait variability to estimate how trait diversity within species varies across species and environmental gradients. Yet variance and related metrics are often interpreted without considering their intrinsic dependence on the mean, as described by the empirical Taylor's power ...

Hidden Losses: Assessing the Risk of Coextinction Among Ectoparasitic Flies and Their Bat Host Species in Brazil

Animal Conservation, EarlyView.
The potential impact of bat species extinction on the number of their ectoparasitic fly species, based on interaction data for Brazil. As bat host species are removed over time, more connected species (green) would experience steeper declines and lead to greater ectoparasite losses when compared to a random extinction model (gray).

Combined effects of the landscape and crop management on ant communities

Agricultural and Forest Entomology, EarlyView.
At small spatial scales, agricultural management acts as a stronger ecological filter than landscape context, significantly shaping ant community composition. Species richness and frequency did not differ among treatments, indicating the predominance of generalist species.

Empirical prediction of organic matter digestibility in grasses, legumes and their mixtures from dairy farms in Atlantic Spain

Grassland Science, EarlyView.
Abstract This study characterized the chemical composition and organic matter digestibility (OMD) of herbage from commercial dairy farms in Galicia (NW Spain), a humid‐temperate Atlantic region, and developed empirical prediction equations for OMD based on routine wet‐chemistry traits.
