Estimating aboveground live understory vegetation carbon in the United States

Environmental Research Letters, 2017
Despite the key role that understory vegetation plays in ecosystems and the terrestrial carbon cycle, it is often overlooked and has few quantitative measurements, especially at national scales.

Reindeer grazing induces spatial and functional shifts in root systems of boreal pine forests

Oikos, EarlyView.
The spatial distribution of roots, laterally and vertically, is critical for nutrient and water uptake and for driving root‐associated carbon inputs and turnover. Large herbivores, such as reindeer, influence ecosystems belowground by altering aboveground vegetation composition and soil microclimate.

The interacting effects of precipitation and microhabitat on non‐native seed predation are contingent on temporal dynamics

Oikos, EarlyView.
Understanding how different drivers of global change interact to shape ecological processes remains a major challenge in ecology. Climate change is reshuffling the interactions that structure communities, with major implications for biological invasions.

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 ...

Management of Hickory Forest Understory Vegetation Increases Ecosystem Carbon Sequestration, But It Also Increases Soil Greenhouse Gas Emissions in the Short Term

Agronomy
Managing forest understory has a significant impact on soil greenhouse gas (GHG) emissions and the ecosystem’s capacity for carbon sequestration. However, its specific impacts and mechanisms within hickory (Carya cathayensis Sarg) forests remain unclear.

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 ...

Pairing Spruce Budworm Control and Minimal Understory Perturbations: Effects of Btk Spraying Frequency in Boreal Forests

Ecology and Evolution
Since 1985, more than 10 million hectares of Canadian forests have been treated against spruce budworm (SBW) epidemics using the Btk biological insecticide.

Species and Richness of Understory Vegetation Regulate Soil Phosphorus Availability via Shifts in Microbial Communities and P-Cycling Functional Genes in Poplar Plantations

Agronomy
Continuous monoculture in poplar plantations often leads to declining soil nutrient availability and productivity. Phosphorus (P), in particular, frequently becomes a key limiting factor due to its high fixability and low chemical availability in the ...

Social‐ecological sustainability of olive farming in the Mediterranean: A review of current practices and an agroecological perspective

People and Nature, EarlyView.
Abstract Olive farming represents a prime example of a biodiversity‐rich land‐use system in the Mediterranean, deeply rooted in a long history and cultural traditions, yet it faces mounting challenges from climate change, biodiversity loss, and declining economic viability that put its sustainability at risk.

Perspectives and behaviors surrounding planting practices in North America inform genetic conservation realities for American ginseng (Panax quinquefolius)

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
