Abstract BACKGROUND Livestock production contributes largely to climate change and methane (CH4) from enteric fermentation is the primary greenhouse gas emitted from ruminants. Thus, developing effective strategies to reduce the impact of ruminant production on the environment is crucial, and the combination of CH4 mitigating agents may be a viable ...

Abstract Climate change is projected to cause elevated precipitation in northern Europe, leading to increased runoff of terrestrial matter to coastal areas. The consequences for food web production and ecosystem function remain unclear. A mesocosm experiment was performed to investigate the impacts of elevated terrestrial matter input, using a natural ...

Abstract Streams naturally receive allochthonous particulate organic materials, but human activity may contribute additional plastic litter inputs, which can affect ecosystem functioning. Our objective was to assess the effect of plastic and bioplastic inputs on microbial biomass and function in a pristine mountain stream.

Blooms of filamentous cyanobacteria reduce zooplankton quality and pelagic food web efficiency
Abstract Cyanobacterial blooms in marine and freshwater ecosystems have increased in magnitude, frequency, and distribution worldwide during recent decades. Filamentous cyanobacteria are of unsuitable size for mesozooplankton feeding and of poorer nutritional quality than other phytoplankton taxa. The production and quality of higher trophic levels are

Abstract Benthic biofilms on cobbles (i.e., epilithic biofilms) control the uptake of soluble reactive phosphorus (SRP) and ammonium (NH4+) in headwater streams. However, nutrient uptake by biofilms in higher‐order rivers, particularly those affected by anthropogenic nutrient inputs and hydrological regulation, remains poorly understood.

Key Regulators of Parasite Biology Viewed Through a Post‐Translational Modification Repertoire
ABSTRACT Parasites are the leading causes of morbidity and mortality in both humans and animals, imposing substantial socioeconomic burdens worldwide. Controlling parasitic diseases has become one of the key issues in achieving “One Health”. Most parasites have sophisticated life cycles exhibiting progressive developmental stages, morphologies, and ...
