Comparison of taxonomic and size-based approaches to determine the effects of environment and disturbance on invertebrate communities in coastal Chile

open access: yesEcological Indicators, 2022
The frequency and intensity of extreme events in coastal wetlands is increasing due to climate change. These, in combination with other threats such as habitat loss, can have strong effects on the biodiversity and ecosystem services of coastal wetland ...

Environmental fate of the anti-parasitic ivermectin in an aquatic micro-ecological system after a single oral administration [PDF]

open access: yesPeerJ, 2019
Background Ivermectin (IVM) has been widely used in the aquaculture industry since its efficacy against parasites. However, the degradation of IVM was very slow in aquatic environments and the environmental fate of IVM in a complete aquatic system was ...

Fast but transient recovery of aquatic and terrestrial communities after a large dam removal

open access: yesFrontiers in Ecology and Evolution, 2023
IntroductionEcological restoration through dam removals receives increasing attention from scientists, environmental managers and policy makers. However, most dam removal projects focus on small structures (< 10 m in height) and on few ecosystem ...

Impacts of Warming on Reciprocal Subsidies Between Aquatic and Terrestrial Ecosystems

open access: yesFrontiers in Ecology and Evolution, 2021
Cross-ecosystem subsidies are important as their recipients often rely on them to supplement in situ resource availability. Global warming has the potential to alter the quality and quantity of these subsidies, but our knowledge of these effects is ...

Terrestrial–aquatic linkages in spring-fed and snowmelt-dominated streams

open access: yesJournal of Freshwater Ecology, 2017
The importance of trophic linkages between aquatic and terrestrial ecosystems is predicted to vary as a function of subsidy quantity and quality relative to in situ resources. To test this prediction, I used multi-year diet data from Bonneville cutthroat
