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.

Seasonal variations in planktonic food web structure affect stability by shifting the distribution of energy fluxes

Oikos, EarlyView.
Seasonality in temperate ecosystems shapes species phenology, influencing interactions and food web structure. Variations in species richness and biomass affect trophic interaction strength, a crucial factor for community stability, which can be assessed through energy fluxes – an essential indicator of ecosystem function.

Comparison of Conventional, Rake, and Sonar‐Based Biophysical Habitat Measurements in a Shallow Ontario River

River Research and Applications, EarlyView.
ABSTRACT Knowledge of habitat availability is critically important for the management and recovery of freshwater species. Quantifying habitat availability often requires fine‐scale sampling at point‐based locations across a large geographic extent, which can be laboursome.

Multitrophic diversity effects depend on consumer specialization and species-specific growth and grazing rates [PDF]

, 2014
Ecosystem functioning is affected by horizontal (within trophic groups) and vertical (across trophic levels) biodiversity. Theory predicts that the effects of vertical biodiversity depend on consumer specialization.

Synergistic and Antagonistic Effects of Chemical Pollutants and Parasitic Fungi on Cyanobacterial Metabolism

Environmental Toxicology, EarlyView.
ABSTRACT Freshwater ecosystems are increasingly impacted by anthropogenic pollutants, including the widely used herbicide metolachlor (MET) and cigarette butt (CB) litter. Parasites represent an additional biotic stressor that can modulate pollutant effects on their hosts.
