Birch (Betula papyrifera) × white spruce (Picea glauca) interactions in mixedwood stands: implications for management

open access: yesJournal of Forest Science, 2013
Current British Columbia forest regulations drive the regeneration management towards pure conifer stands rather than remaining in a mixed-species condition. This approach may result in unnecessary vegetation control.

TreeSegAgent: Agentic tree instance segmentation via a multi‐anchor pipeline

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Individual‐tree segmentation from three‐dimensional forest point clouds underpins forest inventory, biomass estimation and ecosystem monitoring, but remains challenging in structurally complex stands, where vertical heterogeneity and point‐density degradation weaken the robustness of centre‐offset‐based instance grouping.

Seasonal Habitat Selection by a Threatened Ungulate in an Industrializing Boreal Landscape

open access: yesAnimal Conservation, EarlyView.
Understanding habitat selection by Threatened wood bison in landscapes characterized by anthropogenic disturbance is important for conservation planning. During summer and winter, bison selected for linear (e.g., roads, seismic lines, pipelines) and polygonal (e.g., well sites) disturbances, unless there were high densities of linear features.

Delivery and adherence of biomarker‐guided antibiotic treatment protocols in the ADAPT‐Sepsis clinical trial: an in‐trial descriptive process evaluation of daily procalcitonin‐ and C‐reactive protein‐guided protocols

open access: yesAnaesthesia, EarlyView.
Summary Introduction Biomarker‐guided antibiotic protocols using daily procalcitonin or C‐reactive protein have been proposed to optimise antibiotic duration in sepsis. This pre‐planned process evaluation of the ADAPT‐Sepsis trial examined delivery and clinician adherence to procalcitonin‐ and C‐reactive protein‐guided protocols.
