Refining techniques for high‐frequency monitoring of chlorophyll a fluorescence in estuarine systems

Limnology and Oceanography: Methods, EarlyView.
Abstract Concentrations of the photosynthetic pigment chlorophyll a are commonly used as a proxy for phytoplankton biomass in aquatic systems. Traditional methods for extracting chlorophyll a in discrete samples limit measurement frequency, while in situ sensor technology provides high frequency chlorophyll a fluorescence measurements at a more ...

One Assay to Rule Them All: Development of a Global Environmental DNA Tool to Support Range‐Wide Surveys of an Imperiled Sawfish and Its Application in the Eastern Tropical Pacific

Ecology and Evolution, Volume 16, Issue 6, June 2026.
To identify promising locations where Largetooth Sawfish, Pristis pristis, may persist, a novel species‐specific Droplet Digital PCR (ddPCR) assay was designed capable of detecting a single copy of DNA, with in silico and in vitro validation experiments indicating functionality across the species' historical range.

FMRI Approaches to Mapping Cerebrovascular Reactivity: Comparison of Gradient Echo BOLD and Spin Echo BOLD With Arterial Spin Labeling

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3309-3321, June 2026.
ABSTRACT Purpose To compare markers of cerebrovascular reactivity (CVR) measured with Gradient Echo (GE, T2*w) and Spin‐Echo (SE, T2w) BOLD fMRI with quantitative physiological CVR measured using ASL. Methods CVR, the ability of blood vessels to dilate and increase cerebral blood flow (CBF), can be investigated with ASL fMRI but has a low signal‐to ...
