Urban freshwater ecosystems are increasingly exposed to mixtures of pollutants, including per- and polyfluoroalkyl substances (PFAS). However, their ecological effects remain poorly understood, especially in tropical regions with limited sanitation infrastructure. This study investigated PFAS contamination, water quality, and microbial community structure in Pampulha Lake, a tropical urban reservoir in southeastern Brazil. Spa...

The objective of this study was to quantitatively assess the energy recovery potential from both biogas and the incineration of dewatered sludge, aiming to meet the energy demand of a small municipal wastewater treatment plant (MWTP) with a treatment capacity below 50 L s −1 . The energy potential of sludge incineration was characterized based on its gross calorific value, while energy production from biogas generated during t...

Myeloperoxidase (MPO) has been associated with a broad range of chronic inflammatory diseases since activated MPO catalyzes the production of HOCl, triggering both oxidative stress and inflammation. Since benzohydrazides are known as MPO inhibitors, a series of six N '-phenylbenzohydrazides and one quinazolin-4(3 H )-one analogue was evaluated through in vitro assays to measure inhibition of MPO, superoxide dismutase (SOD), an...

Predator–prey interactions are important drivers of adaptation in aquatic communities, shaping the behavior of invertebrates with cascading effects on community dynamics. Behavioral responses, such as moving with the downstream current (drift) or altering the timing of emergence, are strategies that reduce the risk of predator encounters. These prey responses have been extensively studied over the last decades. However, much o...

Coral exhibits substantial variation in pelagic larval duration, dispersal range, and population connectivity. In this study, we used reduced representation genotyping to compare the genetic structure of Caribbean reef-building species along the southeastern Dominican Republic coastline to assess connectivity within the likely dispersal kernel. Despite relatively small geographic distance between reefs, species-specific differ...
