Effects of Hardwood Content on Balsam Fir Defoliation during the Building Phase of a Spruce Budworm Outbreak

open access: yesForests, 2018
Defoliation by spruce budworm (Choristoneura fumiferana Clem.) on balsam fir (Abies balsamea (L.) Mill.) is more severe in fir than in mixed fir-hardwood stands.

Meteorological versus spatial drivers of the spatial synchrony of forest insect pest outbreaks in North America

open access: yesOikos, EarlyView.
Spatial synchrony of population fluctuations has major consequences for the impacts of forest insect pest outbreaks at regional scales. We tested the predictions that the strength and drivers of this synchrony would differ among species according to their dispersal abilities and feeding guilds.

Playground tree diversity: A driver of well‐being in preschool children

open access: yesPeople and Nature, EarlyView.
Abstract Urban greenspaces benefit mental health in adults, with increasing evidence that biodiversity might also play a role. However, we know very little about the impact of urban biodiversity on preschool children's well‐being, despite the critical importance of the formative years.

Patterns and Drivers of Pine Processionary Moth Defoliation in Mediterranean Mountain Forests

open access: yesFrontiers in Ecology and Evolution, 2019
Insect defoliations are one of the threats of forests health, and climate warming may enhance the occurrence of more severe outbreaks. Thus, understanding the spatial and temporal patterns of insect defoliation may provide valuable information to infer ...

Towards an evidence‐based and research‐driven restoration strategy for Britain's temperate rainforests

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Woodlands globally are threatened by environmental change and biodiversity loss. Temperate rainforests are an ecologically rich ecosystem found in wet regions of the temperate zone, and Britain has the potential for major temperate rainforest coverage in its nature‐depleted landscape.

Assessing Pine Processionary Moth Defoliation Using Unmanned Aerial Systems

open access: yes, 2017
Pine processionary moth (PPM) is one of the most destructive insect defoliators in the Mediterranean for many conifers, causing losses of growth, vitality and eventually the death of trees during outbreaks.

Potential drivers of fast growth in Paulownia

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Trees in the genus Paulownia play a crucial role in sustainable forestry, rural economic development, and carbon mitigation due to their rapid growth, exceptional hardwood properties, and prominent carbon sequestration capacity. This review highlights the societal value of Paulownia trees and synthesizes several potential drivers of extraordinarily ...

Concentration of Potassium, Magnesium, and Iron of Brachiaria humidicola (Rendle Schweick) at Various Cultivation Methods and Defoliation Intervals

open access: yesAnimal Production: Indonesian Journal of Animal Production, 2006
The existence of weeds significantly decreases the rate of production and quality of herbage.  Physical weed control by defoliation could be expected to sustain quality and production of herbage, and is able to control weeds expansion.

Influence of intensity of post‐veraison defoliation or shoot trimming on vine physiology, yield components, berry and wine composition in Aglianico grapevines

open access: yes, 2017
Background and Aims Post-veraison trimming and defoliation have been proposed as strategies to decrease the concentration of berry carbohydrate at harvest and of wine alcohol, but it is unclear which of these two pruning techniques is more suitable and ...
