Genetic structure of the northern house mosquito (Diptera: Culicidae) in a WNV-susceptible area.

Mosquitoes from the Culex pipiens complex are found worldwide and have been the focus of numerous studies due to their role as vectors of human pathogens. We investigated the population genetic structure of Cx. pipiens s.

Delimitation of Endangered Species (Anura: Telmatobiidae) of the Chilean Salt Puna.

Clarifying the taxonomic status and distribution of endangered species is crucial to their conservation. In this study, we contrasted different lines of evidence (morphology, mtDNA, and nucDNA: microsatellites and SNP) to clarify the taxonomic status of endangered water frog species and unidentified populations that inhabit the Salt Puna in Chile. We studied population differentiation and species divergence by performing morphometric, population genetic and species delimitation analyses.

The timing of marine heatwaves during the moulting cycle affects performance of decapod larvae.

Marine heatwaves (MHW) pose an increasing threat and have a critical impact on meroplanktonic organisms, because their larvae are highly sensitive to environmental stress and key for species' dispersion and population connectivity. This study assesses the effects of MHW on two key moulting cycle periods within first zoea of the valuable crab, Metacarcinus edwardsii. First, the changes in swimming behaviour during zoea I were recorded and associated to moult cycle substages.

Chemical-defensome and whole-transcriptome expression of the silverside fish Basilichthys microlepidotus in response to chronic pollution in the Maipo River basin, Central Chile.

Pollution is a major global concern affecting biodiversity, particularly of freshwater species. Populations have developed mechanisms to deal with pollution, such as the chemical defensome, which is a set of genes involved in maintaining internal stability. Pollution significantly affects the Maipo River basin in Chile.

Circum-Mediterranean influence in the Y-chromosome lineages associated with prostate cancer in Mexican men: A Converso heritage founder effect?

Prostate cancer is the second most common neoplasia amongst men worldwide. Hereditary susceptibility and ancestral heritage are well-established risk factors that explain the disparity trends across different ethnicities, populations, and regions even within the same country. The Y-chromosome has been considered a prototype biomarker for male health.
