A combined approach for early in-field detection of beech leaf disease using near-infrared spectroscopy and machine learning

Frontiers in Forests and Global Change, 2022
The ability to detect diseased trees before symptoms emerge is key in forest health management because it allows for more timely and targeted intervention.

Modeling tolerant hardwood sapling density and occurrence probability in the Acadian forests of New Brunswick, Canada: Results 14 years after harvesting

The Forestry Chronicle, 2021
Natural forest regeneration after natural or anthropogenic disturbance is difficult to predict given its high variability. The process is poorly documented for commercial northern hardwood species in the Acadian forest of eastern Canada.

Unexpected presence of Fagus orientalis complex in Italy as inferred from 45,000-year-old DNA pollen samples from Venice lagoon

BMC Evolutionary Biology, 2007
Background Phylogeographic analyses on the Western Euroasiatic Fagus taxa (F. orientalis, F. sylvatica, F. taurica and F. moesiaca) is available, however, the subdivision of Fagus spp.

Conservación de los recursos fitogenéticos: uso inteligente de la biodiversidad

Revista Biológico Agropecuaria Tuxpan, 2018
Los recursos fitogenéticos están representados por toda la variedad y combinaciones posibles de rasgos que permiten a las especies vegetales adaptarse a los cambios en el medio; a mayor cantidad de rasgos y combinaciones, mayor es la probabilidad de que

The role of the climate niche in repeated abrupt tree declines and ecotone dynamics in the Appalachian Mountains during the Holocene [PDF]

Frontiers of Biogeography
Forests in eastern North American did not achieve a stable composition during the Holocene. Both prolonged and abrupt shifts in the distributions of tree species were common. Studying the dynamics involved can help anticipate the responsiveness of forest

Monitoring the effects of ovariectomy on seasonal movement behavior in suburban female white‐tailed deer using internet of things‐enabled devices

Wildlife Biology, EarlyView.
Abundant deer populations often cause conflicts in suburban communities, yet traditional population reduction methods, such as controlled hunting, can be challenging to implement. Fertility control, specifically through ovariectomy, can limit reproduction and reduce populations in certain settings, but its effect on movement behavior remains poorly ...

A new Phylloporus from two relict Fagus grandifolia var. mexicana populations in a montane cloud forest [PDF]

, 2011
A new species, Phylloporus fagicola, has been discovered growing in association with two relict populations of Fagus grandifolia var. mexicana in the subtropical region of central Veracruz (eastern Mexico).

Quantifying microhabitat selection of snowshoe hares using forest metrics from UAS‐based LiDAR

Wildlife Biology, EarlyView.
Identifying the spatial and temporal scale at which animals select resources is critical for predicting how populations respond to changes in the environment. The spatial distribution of fine‐scale resources (e.g. patches of dense vegetation) are often linked with critical life‐history requirements such as denning and feeding sites.

Conspecific negative density dependence in American beech

Forest Ecosystems, 2017
Background One of the most important drivers of forest biodiversity is conspecific negative density dependence (CNDD), a reduction in performance when conspecific densities are high.
