Microplastics—synthetic particles ranging in size from 1 μm to 5 mm—are now widely recognised as an emerging environmental issue due to their ubiquity across ecosystems. While most research has focused on marine environments, important knowledge gaps remain regarding their occurrence in freshwater systems, particularly in remote and high-altitude ecosystems. Given the increasing human use of these environments, understanding p...

Iron is an essential micronutrient for brain development, participating in mitochondrial respiration, myelination, and neurotransmitter synthesis. However, previous studies have demonstrated that excessive iron during early postnatal life induces oxidative reactions, leading to mitochondrial dysfunction and synaptic failure. These alterations compromise energy metabolism and neuronal integrity, contributing to long-lasting cog...

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...

Rapid glacier retreat across the Arctic is transforming coastal landscapes and generating a growing number of previously non-existent aquatic habitats. In Svalbard, this process has led to the formation and expansion of coastal lagoons, including a substantial proportion of newly emerged paraglacial systems. Despite their increasing abundance, these environments remain poorly represented in Svalbard research and monitoring pro...

Neotropical freshwater biodiversity is remarkable, mainly due to historical, biotic, and environmental processes. Landscape connectivity can promote or restrict species dispersal in fish metacommunities, thereby influencing the diversity and phylogenetic structure of communities. This study evaluated whether structural landscape variables of the Tramandaí River basin affect the phylogenetic diversity of the component communiti...
