Water pollution caused by ash from grassland fires alters the molecular, biochemical, and morphological biomarkers of non-biting midge larvae.

The frequency and intensity of wildfires have been increasing in many parts of the world, which may result in biodiversity loss. Wildfires can devastate plant communities, generating toxic ash that pollutes watercourses through runoff. However, our understanding of the effects of ash exposure on aquatic biodiversity is still limited.

A new Ceratomyxa (Cnidaria: Myxosporea) infecting the ornamental fish species Pterophyllum scalare from the Amazon Region, Brazil.

A new parasite of the Class Myxozoa is described in the gallbladder of the ornamental angelfish Pterophyllum scalare, in two municipalities in the state of Amapá, Brazil, based on morphological, morphometric and phylogenetic descriptions. From October 2022 to August 2024 fifty-five angelfish specimens were sampled in Macapá (n=10) and Tartarugalzinho (n=45). Slightly arched mixospores were observed by light microscopy and had characteristics consistent with those of the genus Ceratomyxa.

Synchronized Photoluminescence and Electrical Mobility Enhancement in 2D WS through Sequence-Specific Chemical Passivation.

Two-dimensional (2D) semiconducting dichalcogenides hold exceptional promise for next-generation electronic and photonic devices. Despite this potential, the pervasive presence of defects in 2D dichalcogenides results in carrier mobility and photoluminescence (PL) that fall significantly short of theoretical predictions. Although defect passivation offers a potential solution, its effects have been inconsistent.

New genus of Pleminiini Brunner von Wattenwyl, 1878 (Orthoptera: Tettigoniidae: Pseudophyllinae) from the Colombian Andes.

The Pleminiini tribe (Pseudophyllinae: Tettigoniidae) currently comprises 51 genera and 227 valid species with a Neotropical and Afrotropical distribution. Herein, the new monotypic genus Muscuspina Mendes gen. nov.
