Nature of Phytoplankton Communities in the Southern Hemisphere Shallow Lakes, With an Emphasis on the Presence of Submerged Aquatic Vegetation: A Review

Aquaculture, Fish and Fisheries, Volume 5, Issue 3, June 2025.
ABSTRACT Differences in the ecological stability of shallow lakes are reflected in the functional nature of the distinct phytoplankton communities in the Southern Hemisphere. Recent studies have highlighted growing uncertainties of the previous concepts regarding phytoplankton cosmopolitanism, suggesting these communities may be more regionally ...

The social–ecological fabric of freshwater fish management: Accounting for feedback loops in human–fish interactions

Ecosphere, Volume 16, Issue 4, April 2025.
Abstract A holistic view of nature, which situates human relationships and actions within ecosystems, can broaden our understanding of environmental problems and expand the scope and efficacy of potential solutions. Social–ecological systems (SES) research attempts to take this broad perspective.

Aquatic macrophyte growth season in Central and Northern European Union and the implications for aquatic macrophyte risk assessments for herbicides

Integrated Environmental Assessment and Management, Volume 20, Issue 4, Page 1125-1139, July 2024.
Abstract Under current European Union regulation, the risks to aquatic organisms must be assessed for uses of plant protection products (PPPs) that may result in exposure to the environment. For herbicidal PPPs, aquatic macrophytes are often the most sensitive taxa.

Sensitivity of amphibian embryos to timing and magnitude of present and future thermal extremes

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 341, Issue 4, Page 377-388, May 1, 2024.
Abstract Ongoing climate change is increasing the frequency and intensity of extreme temperature events. Unlike the gradual increase on average environmental temperatures, these short‐term and unpredictable temperature extremes impact population dynamics of ectotherms through their effect on individual survival.
