Genomics-based timely detection of dengue virus type I genotypes I and V in Uruguay.

Laboratorio de Virus Emergentes/reemergentes. Unidad de Virología, Departamento de Laboratorios de Salud Pública, Portugal.
This study details a genomics-based approach for the early detection of mosquito-borne pathogens, marked by Uruguay's first ever complete genomic sequencing of Dengue Virus type I genotypes I and V. This pioneering effort has facilitated the prompt identification of these genotypes within the country, enabling Uruguayan public health authorities to develop timely and effective response strategies. Further integrated into this approach is a climate-driven suitability measure, closely associated with Dengue case reports and indicative of the local climate's role in the virus's transmission in the country within the changing climate context.

Background: Climate change presents several challenges to public health and its professionals. This article aims to fill a significant gap in the current literature by understanding physicians' perceptions of their role in educating others about health adaptation to climate change. It also explores their knowledge of health policies related to this issue in Portugal and their perceived influence on the development of adaptation policies at both local and national levels within the health sector.

Strontium isotope (Sr/Sr) analysis with reference to strontium isotope landscapes (Sr isoscapes) allows reconstructing mobility and migration in archaeology, ecology, and forensics. However, despite the vast potential of research involving Sr/Sr analysis particularly in Africa, Sr isoscapes remain unavailable for the largest parts of the continent. Here, we measure the Sr/Sr ratios in 778 environmental samples from 24 African countries and combine this data with published data to model a bioavailable Sr isoscape for sub-Saharan Africa using random forest regression.

The development of management strategies for the promotion of sustainable fisheries relies on a deep knowledge of ecological and evolutionary processes driving the diversification and genetic variation of marine organisms. Sustainability strategies are especially relevant for marine species such as the European sardine (Sardina pilchardus), a small pelagic fish with high ecological and socioeconomic importance, especially in Southern Europe, whose stock has declined since 2006, possibly due to environmental factors. Here, we generated sequences for 139 mitochondrial genomes from individuals from 19 different geographical locations across most of the species distribution range, which was used to assess genetic diversity, diversification history and genomic signatures of selection.
