The marine and estuarine bony fishes (Teleostei) of the Golfão Maranhense on the eastern Amazon coast, northern Brazil.

The Golfão Maranhense is an extensive estuarine complex that provides nursery grounds and other habitats for several fish species, as well as a wealth of resources for the coastal and estuarine artisanal fisheries of the Maranhão state, in northern Brazil. The present study provides a comprehensive inventory of marine and estuarine teleost fishes of the Golfão Maranhense based on field samplings, analyses of voucher specimens from local collections and literature data. This inventory presents a total of 163 species of teleosts belonging to 107 genera, 57 families and 27 orders.

Applying Bayesian statistics and MCMC to ozone reaction kinetics: Implications for water treatment models.

Ozonation is an advanced oxidation process widely used for water and wastewater treatment. The pseudo-first-order kinetic model is frequently applied for designing and scaling this treatment, offering insights into oxidation pathways through ozone reaction rate constants (k and k) and the exposure ratio term (R). This work evaluates the kinetic constants for ozonation reactions involving three pharmaceuticals, caffeine (CAF), atenolol (ATL), and propranolol (PRO), classified as emerging contaminants (ECs), with the aim of guiding future research and industrial applications for various pollutants.

Optimizing ozone treatment for pathogen removal and disinfection by-product control for potable reuse at pilot-scale.

Reclaimed water poses environmental and human health risks due to residual organic micropollutants and pathogens. Ozonation of reclaimed water to control pathogens and trace organics is an important step in advanced water treatment systems for potable reuse of reclaimed water. Ensuring efficient pathogen reduction while controlling disinfection byproducts remains a significant challenge to implementing ozonation in reclaimed water reuse applications.

Molecular identification of sharks from the genus Sphyrna (Elasmobranchii: Chondrichthyes) in Maranhão Coast (Brazil).

Sharks of the genus Sphyrna are under intense exploitation globally. In Brazil's northern coast, this genus represents a high proportion of fisheries landings and comprises four species. However, due to difficulty of specific identification when specimens are landed, most of the records are limited to the genus level.

DNA Barcoding Culicoides Biting Midges (Diptera: Ceratopogonidae) in Northeast Brazil.

Biting midges of the genus Culicoides are small insects associated with the transmission of several pathogens, which requires the correct identification of the species, for implementation of effective strategies against these insects. However, many species are difficult to identify only by morphological characters. Therefore, the use of molecular methods can help in the taxonomy and systematics of this group.
