Seasonal dynamics of lingonberry and blueberry spectra
Silva Fennica, 2019 Accurate mapping of the spatial distribution of understory species from spectral images requires ground reference data which represent the prevailing phenological stage at the time of image acquisition.

Coexisting ant species differ in ability to meet their intrinsic nutritional needs
Oikos, EarlyView.Coexisting species are often assumed to reduce competition by foraging for foods that differ in nutrient composition, but few studies test whether field nutritional differences correspond to intrinsic differences in macronutrient selectivity. We compared field estimates of worker trophic position (tissue isotopes: δ15N) and worker tissue stoichiometry (

Green pathways to mental health: Relationships between treescapes and well‐being and distress
People and Nature, EarlyView.Abstract We aimed to evaluate the mental health benefits and possible mechanisms of objective and subjective treescape exposures whilst also accounting for relationships with residential area greenspace in general. Independent variables were objective measures of residential neighbourhood tree cover density and woody linear features, and a subjective ...

Identifying knowledge barriers to agroforestry adoption and co‐designing solutions to them
People and Nature, EarlyView.Abstract Compared to monocultures, agroforestry can promote biodiversity, ecosystem functioning and climate resilience, whilst maintaining or enhancing production and profits. Despite this, uptake in temperate regions remains low. Knowledge gaps amongst land managers are a primary barrier to uptake, but little is known about which aspects of ...

UAV Remote Sensing for Biodiversity Monitoring: Are Forest Canopy Gaps Good Covariates?
Remote Sensing, 2018 Forest canopy gaps are important to ecosystem dynamics. Depending on tree species, small canopy openings may be associated with intra-crown porosity and with space among crowns.

PLANTS, PEOPLE, PLANET, EarlyView.American ginseng is a shade‐obligate, North American medicinal plant that is widely traded and used internationally. To meet global demand, ginseng is cultivated in forest farms in the Appalachian region of the USA and field‐based artificial shade farms in two regions: Ontario, Canada and Wisconsin, USA. We conducted social research leveraging in‐depth
