ABSTRACT One of the largest wetlands on Earth, the Brazilian Pantanal contains roughly 10 000 natural lakes, about 1000 of which are hypersaline. In these environmentally stressful settings, animal life struggles to survive, while cyanobacteria form extensive mats.

Environmentally Friendly Lubricants: The Role of Biopolymers in Modern Tribology
Biomass‐derived biopolymers modified for green tribology applications with reduced friction, wear, and environmental footprint. ABSTRACT Energy losses due to friction and wear are a major challenge for the energy efficiency and sustainability of mechanical systems, motivating the development of green tribology strategies.

A hysteretic model predicts a time lag in the response of herbaceous layer variables (e.g., cover, diversity) to decreasing N deposition. To the contrary, virtually all such variables displayed a surprising sensitivity to decreased N. ABSTRACT Increases in nitrogen (N) emissions during the 20th century resulted in the atmospheric deposition of N ...

Low‐Head Dam Removal Restores Biofilm Structure but Not Function in a Temperate Stream
ABSTRACT Barrier removal is a common stream restoration practice aimed at restoring longitudinal connectivity, yet its effects on biofilm structure and function, through alteration of near‐bed hydrodynamics, remain unclear. Using a space‐for‐time substitution approach, we assessed how the presence and removal of a low‐head dam affect biofilm structure ...

Effects of aquatic vegetation type on denitrification [PDF]
In a microcosm 15N enrichment experiment we tested the effect of floating vegetation (Lemna sp.) and submerged vegetation (Elodea nuttallii) on denitrification rates, and compared it to systems without macrophytes.
