Phytoplankton iron limitation in the Atlantic Southern Ocean driven by seasonal mixed‐layer dynamics

open access: yesLimnology and Oceanography Letters, EarlyView.
Abstract Phytoplankton blooms in the Southern Ocean (SO) are seasonally limited by light and micronutrients. As such, regional variations in iron supply from mixed‐layer winter entrainment are expected to impact the extent of seasonal iron limitation. Here, we determined seasonal iron limitation in the Atlantic SO by conducting iron addition incubation

Environmental Variables Outpace Biotic Interactions in Shaping a Phytoplankton Community

open access: yesDiversity
We evaluated the main environmental factors (abiotic and biotic) driving the phytoplankton community in a shallow tropical reservoir located in an environmentally protected area.

Extending monitoring with sediment archive approaches: Comparison of biomonitoring, metabarcoding, and biomarkers to assess past phytoplankton dynamics

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Sedimentary archives can provide valuable insights into the study of anthropogenic impacts on marine and limnic ecosystems over centennial and millennial timescales, potentially extending the temporal breadth of observation‐based biomonitoring.

Environmental Impact of Silicic Magmatism in Large Igneous Province Events

open access: yesGeophysical Monograph Series, Page 133-151., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

A correction model for quenching effects on chlorophyll a fluorescence measurements in lakes

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Characterizing the vertical structure of phytoplankton biomass is key to understanding the light, nutrient, and mixing dynamics driving lake ecosystems. In situ fluorometry is widely used in limnology to obtain chlorophyll a (Chl a) measurements as proxies for phytoplankton biomass.
