Harbor Porpoise and Beluga Whale Habitat Use in the Saguenay‐St. Lawrence Marine Park (Canada) Revealed by a Combination of Visual and Acoustic Survey

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Studying habitat use of cetaceans that spend most of their lives underwater poses challenges, prompting the use of complementary methods. Non‐invasive methods, land‐based surveys (LBS) and passive acoustic monitoring (PAM), were used to characterize occurrence patterns of beluga whales, harbor porpoises, and vessels in the Saguenay–St ...

Local Chemical Gradients in a Mammalian Cortex Measured In Vivo With a Silicon Nanodialysis Mass Spectrometry Platform

open access: yesAngewandte Chemie, Volume 138, Issue 26, 22 June 2026.
Fluorescence image of the coronal slice of mouse brain where multiple neurochemicals have been measured in vivo with a nanodialysis platform coupled to CE‐MS to reveal strong millimeter‐scale spatial chemical gradients. Formation and maintenance of such local chemical compartments in the otherwise diffusion‐homogeneous cortex indicates strong ...

Endophyte‐induced systemic spatial reprogramming of metabolism in Populus trichocarpa roots under drought

open access: yesNew Phytologist, Volume 251, Issue 1, Page 438-454, July 2026.
Summary Beneficial, facultative endophytes help plants thrive in challenging environments by altering their host's metabolism, but how these cellular scale metabolic changes propagate to the systems biology scale is unknown. In this work, we employed a high‐resolution chemical imaging approach to map metabolic changes at the Populus trichocarpa root ...

Simultaneous Generation of Topographic Models and Manning Roughness Coefficient Maps From Tri‐Stereoscopic Satellite Images: Application to the Huarmey River, Peru

open access: yesThe Photogrammetric Record, Volume 41, Issue 195, July/September 2026.
Tri‐stereoscopic PeruSat‐1 imagery enables the simultaneous generation of 0.70 m‐resolution topography and spatially distributed Manning roughness maps, achieving 0.434 m vertical accuracy. Integrated into HEC‐RAS, these products provide consistent, high‐resolution inputs that improve hydraulic modelling and flood risk assessment in data‐scarce river ...
