Leaf area index and topographical effects on turburlent diffusion in a deciduous forest [PDF]
, 2012 In order to investigate turbulent diffusion in a deciduous forest canopy, wind velocity measurements were conducted from late autumn of 2009 to early spring of 2010, using an observation tower 20 m in height located in the campus of Kanazawa University.

Where do we expect to find deep plant roots?
Ecography, EarlyView.Plant roots have been observed up to 70 m in depth – what would compel a plant to root so deeply? Earlier work shows that the climate, soil and drainage all affect rooting depth, but with conflicting results. For example, both the deepest and shallowest roots are found in arid regions.

Resist!: Sustaining forest carbon sequestration and wood production after insect disturbance
Frontiers in Ecology and the Environment, EarlyView.Disturbances from insect pests threaten ecologically and economically important goods and services supplied by forests, including wood production and carbon sequestration. We highlight the factors that influence these services’ resistance, a term quantifying the initial response to disturbance.

Geophysical Research Letters, 2018 The timing of leaf emergence is an important diagnostic of climate change impacts on ecosystems. Here we present the first continental‐scale analysis of multidecadal changes in the timing of spring onset across North American temperate and boreal forests

The western North American forestland carbon sink: will our climate commitments go up in smoke?
Frontiers in Ecology and the Environment, EarlyView.Pathways to achieving net‐zero and net‐negative greenhouse‐gas (GHG) emission targets rely on land‐based contributions to carbon (C) sequestration. However, projections of future contributions neglect to consider ecosystems, climate change, legacy impacts of continental‐scale fire exclusion, forest accretion and densification, and a century or more of ...

Adoption Dynamics of Organic Pesticides Among Cocoa Producers In Two Ecological Zones Of Ghana
Global Challenges, EarlyView.The study explores the dynamics of organic pesticides among cocoa farmers, analyzing factors shaping farmers perception, adoption barriers and enablers, and factors driving the adoption of organic pesticides across different ecological zones. The findings highlight the diverse socio‐economic contexts within which cocoa operates and suggest targeted ...
