Experimental droughts in mesocosms reveal a gradient of tolerance in Alpine stream macroinvertebrates

open access: yesLimnology and Oceanography, EarlyView.
Abstract Prolonged droughts, driven by climate change and human pressures on water resources, are increasing in frequency and intensity, particularly impacting Alpine rivers. Benthic macroinvertebrates are one of the most important structural and functional components of Alpine lotic ecosystems.

Elevated carbon dioxide can boost freshwater zooplankton abundance, while warming may shift community composition, weakening phytoplankton control

open access: yesLimnology and Oceanography, EarlyView.
Abstract Zooplankton communities in ponds and lakes control phytoplankton growth and serve as a food source for higher trophic levels such as fish. Recent experiments have shown that several freshwater zooplankton species as well as the phytoplankton communities on which they feed can be variably affected by rising temperatures, reduced pH and higher ...

Overview of Patagonian Red Octopus (Enteroctopus megalocyathus) Fisheries in Chilean Regions and Their Food Safety Aspects

open access: yesAnimals
Artisanal fisheries in southern Chile rely heavily on the Patagonian red octopus (Enteroctopus megalocyathus) as a valuable resource, contributing significantly to local economies. This octopus species accounts for 25–40% of Chilean octopus landings.

Spatial dynamics of animal‐mediated nutrients in temperate waters

open access: yesLimnology and Oceanography, EarlyView.
Abstract Consumer‐mediated nutrient dynamics (CND), through which animals' metabolic waste products fertilize primary producers, drive variability in nutrient availability in tropical waters. This variability influences primary productivity and community functioning.
