Algal Blooms in Lakes Increase After Wildfire Smoke Events in the Contiguous United States

Global Change Biology Communications, EarlyView.
Temporary pulses of surface chlorophyll‐a are identified following wildfire smoke events in lakes and reservoirs across the United States. ABSTRACT Area burned by wildfire has increased in the contiguous United States and in many places globally in recent years, impacting communities and ecosystems nearby and even far downwind of fires.

Comparison between fluorometry and microscopy‐based phytoplankton assessments in the Laurentian Great Lakes

Limnology and Oceanography: Methods, EarlyView.
Abstract Photosynthetic pigment fluorescence is commonly used in limnology and oceanography as a proxy for phytoplankton biomass. Fluorometry has been used to detect subsurface algal blooms, characterize dynamics of the deep chlorophyll layer, and to provide greater vertical resolution to phytoplankton monitoring.

Unlocking landscape transient dynamics: Integrating traditional ecological knowledge for enhanced analysis of land‐use changes and forest expansion in a Mediterranean ecosystem

People and Nature, EarlyView.
Abstract The Industrial Revolution triggered rural abandonment in Europe and had a profound impact on land configuration and ecosystem dynamics, mainly the growth of forests at the expense of open agricultural habitats. However, rural abandonment has been asynchronous in space and time, depending on regional socio‐economic dynamics.
