Predicting Wave‐Induced Sediment Resuspension at the Perimeter of Lakes Using a Steady‐State Spectral Wave Model

open access: yesWater Resources Research, 2019
A steady‐state spectral wave model, STWAVE, is evaluated as a tool for predicting wave‐induced sediment resuspension in lake littoral zones. Steady‐state wave height and bed‐shear stress estimates are tested against 2 years of high‐frequency wave height ...

Linking variation in genome size to cyst size in chrysophytes

open access: yesJournal of Phycology, EarlyView.
Abstract Genome size varies tremendously across eukaryotes, which often contain far more DNA than expected from their biological complexity. To explain this paradox, selection‐based hypotheses propose that genome size evolves through selection acting on life‐history traits correlated with the phenotypic effects, independent of its genic content.

Saffron aqueous extract effects on paraquat and glyphosate concentration in common carp (Cyprinus carpio) tissues

open access: yesAgricultural &Environmental Letters, Volume 11, Issue 2, December 2026.
Reduced bioaccumulation of PQ and GLY by saffron extract in Common carp (Cyprinus carpio) tissues Abstract Herbicides such as paraquat (PQ) and glyphosate (GLY) pose ecological and public health risks because of their persistence, bioaccumulation, and toxicity to aquatic organisms. This study evaluated whether aqueous saffron extract (Crocus sativus L.)

Freshwater Biodiversity Research in Brazil: Trends from a Systematic Review and Topic Modeling

open access: yesInternational Review of Hydrobiology, Volume 111, Issue 2, December 2026.
ABSTRACT Brazil is a megadiverse country that hosts six major biomes and a vast freshwater network. Despite this richness, research on freshwater biodiversity has been heterogeneous across regions, communities, and time, leaving significant knowledge gaps.

Wildfire in the Surrounding Landscape Alters Limnological Conditions and Plankton Communities in a Tropical Reservoir

open access: yesInternational Review of Hydrobiology, Volume 111, Issue 2, December 2026.
ABSTRACT Wildfires are becoming increasingly frequent and severe as a consequence of climate change. Their impacts on terrestrial ecosystems and on the atmosphere include the release of gases and ash, as well as enhanced soil susceptibility to erosion and the downstream transport of materials into aquatic systems.

Basic limnology of fifty-one lakes in Costa Rica

open access: yesRevista de Biología Tropical, 2003
We visited 51 lakes in Costa Rica as part of a broad-based survey to document their physical and chemical characteristics and how these relate to the mode of formation and geographical distribution of the lakes. The four oxbow lakes were low in elevation
