Toxicity and repellency of the monoterpenoids carvone and eucalyptol on Sitophilus zeamais: contact and fumigation-based interactionsNARA Subscribed
Corn is a globally important crop; however, pest infestations during storage represent a major challenge. The maize weevil, Sitophilus zeamais (Coleoptera: Curculionidae), is a primary pest of stored maize, commonly controlled through phosphine fumigation. Nevertheless, extensive reliance on this insecticide has led to the emergence of resistant populations. Thus, the objective of this study was to evaluate the contact and fum...
Enterococcus spp. are opportunistic bacteria capable of acquiring antimicrobial resistance and virulence traits, facilitating their adaptation to multiple ecological niches. Sternal bursitis, a condition affecting poultry welfare and carcass quality, remains poorly characterized from a microbiological perspective. This study provides the first genomic and phenotypic characterization of Enterococcus isolates from bursitis lesio...
Understanding spatial patterns of extreme precipitation trends is essential for climate risk assessment, particularly in regions characterized by strong climatic heterogeneity and limited monitoring networks, where locally significant trends may be overinterpreted if field significance is not explicitly assessed. This study presents a regional analysis of trends in ten extreme precipitation indices calculated for each of 62 ra...
Ecotoxicological Effect of Kappaphycus alvarezii Extract on Zea mays and Ceriodaphnia silvestriiNARA Subscribed
Marine algae are recognized as promising sources of natural biostimulants in agriculture, with potential applications in seed physiological conditioning. However, the environmental implications of their production, management, and disposal remain insufficiently addressed. This study evaluated the ecotoxicological effects of a commercial Kappaphycus alvarezii extract on Zea mays and Ceriodaphnia silvestrii . Conditioning assays...
Co-60 gamma irradiation induces variation in F₃ watermelon resistance to Macrophomina phaseolinaNARA Subscribed
Gamma radiation has been employed to induce mutations in seeds and to develop disease-tolerant cultivars. This study aimed to assess resistance to Macrophomina phaseolina in F₃ watermelon ( Citrullus lanatus ) genotypes derived from seeds of the cultivar Sugar Baby irradiated with 200 Gy of Co-60 gamma rays. The experiment was conducted in a greenhouse using a completely randomised design, with 14 treatments, and five replicat...
Air pollution remains a persistent environmental and public health concern in urban regions. This study presents a 22-year analysis (2001–2022) of coarse particulate matter (PM 10 ) concentrations across 15 monitoring stations in the Porto Metropolitan Area (PMA), Portugal. The stations, pre-classified by national authorities as traffic, background-urban, background-suburban, or industrial, were used to assess long-term tempor...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
