Disrupting the herd: Recreational boating alters group dispersion within beluga whale herds
The Journal of Wildlife Management, EarlyView.Recreational boating in beluga habitat remains poorly documented. Using land‐based observations in the Saguenay Fjord (Quebec, Canada), we show that increasing recreational boat numbers are associated with a higher probability of changes in beluga herd dispersion, suggesting behavioral disturbance and the need to integrate recreational boating into ...

A novel approach for in situ benthic habitat characterization
Limnology and Oceanography: Methods, EarlyView.Abstract Habitat heterogeneity is a key driver of temporal and spatial variability of subtidal marine benthic biodiversity. However, this makes it a challenging environment in which to measure and quantify the factors driving biodiversity in a consistent manner.

Seismic behavior of tensegrity barrel vaults
, 2009 Tensegrity systems are spatial reticular systems in a state of self-stress. These systems are structures made up of an assembly of pin-jointed pre-stressed continuous tension members (cables) and discontinuous compressive members (struts), arranged in different complex shapes. Their stiffness is the result of a self stress that stabilizes infinitesimal

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Numerical simulation of hydraulic fracturing remains challenging due to the strong coupling between geomechanics and fluid flow when modelling multiple physical mechanisms of rock deformation, fracture evolution and fluid leak‐off. This study develops a coupled hydraulic fracture propagation framework that combines the extended finite element ...

Numerical Modeling of Geological Fault Reactivation Using Sequential Coupling Strategies
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT The interaction between fluid flow and mechanical deformation in fault zones can lead to processes of fault reactivation, triggering potential geomechanical problems such as seismicity, well collapse, fluid migration to shallower layers, and aggravated surface subsidence.
