In contrast to marine organisms, the presence of microplastics (MPs) in freshwater animals remains insufficiently studied. The aim of this study was to identify the occurrence of MPs in the digestive tracts of two fish species from a small lowland river (Widawa R., SW Poland). In total, 202 gudgeons and 187 roaches were collected, of which 54.5% and 53.9% had ingested MP-like particles, respectively. Feeding type and behaviour, sex and capture site (above or below the dam reservoir) did not affect the number of fish with MP-like particles.

Unlike most rivers globally, nearly all lowland Amazonian rivers have unregulated flow, supporting seasonally flooded floodplain forests. Floodplain forests harbor a unique tree species assemblage adapted to flooding and specialized fauna, including fruit-eating fish that migrate seasonally into floodplains, favoring expansive floodplain areas. Frugivorous fish are forest-dependent fauna critical to forest regeneration via seed dispersal and support commercial and artisanal fisheries.

is a rare Coffea species boasting a flavor profile comparable to Arabica coffee () and has a good adaptability to lowland tropical climates. This species faces increasing threats from climate change, deforestation, and habitat fragmentation in its West African homeland. Using 1037 novel SNP markers derived from Genotyping-by-Sequencing (GBS), we revealed the presence of three distinct natural populations (mean Fst = 0.

Article Synopsis
- Denitrification in large tropical rivers plays a crucial role in nitrogen retention, but accurate measurements for seasonal and geomorphological comparisons are challenging.
- Researchers tested a hypothesis linking potential denitrification rates (PDR) to soil and vegetation characteristics in various geomorphic units (GUs) along a section of the Padma River in Bangladesh.
- They found significant relationships between PDR, vegetation cover, and soil moisture, using remote sensing data to model PDR across different seasons, concluding that certain GUs, particularly vegetation islands and bars, are key areas for denitrification.

Land use patterns play a critical role in shaping abiotic conditions, which in turn influence interspecies interactions within aquatic ecosystems. This study tested the hypothesis that catchment management practices significantly alter water parameters and consequently affect the dynamics, importance, and nature of relationships within the zooplankton community structure of a postglacial river (northern Poland). Zooplankton interspecies interactions were assessed using network graph modeling across four diverse catchment sections: natural (NAT), urban (URB), urban/agricultural (URB/AGR), and agricultural (AGR).
