Distribution of genetic diversity in Fagus sylvatica at the north-eastern edge of the natural range

open access: yesSilva Fennica, 2016
An understanding of the genetic variation of the beech, especially at the edge of its natural distribution, is essential because of the change in natural distribution of the species resulting from changing climatic conditions.

Why Are There So Few Insect Predators of Nuts of American Beech \u3ci\u3e(Fagus Grandifolia)?\u3c/i\u3e [PDF]

open access: yes, 2018
American beech, Fagus grandifolia Ehrh., is a common nut-bearing tree of eastern North America. Compared to other North American nut-bearing tree species of comparable geographic range, the nut-infesting insect fauna of American beech is species-poor ...

The climate of a Danish beech wood, Hestehaven, eastern Jutland

open access: yesEcography, 1982
The wind profile in the IBP beech stand and the vertical temperature distribution in the same beech stand and in a neighbouring clearing were investigated. In addition the temperature and humidity conditions in the trunk space of the beech stand and in the clearing were compared. The precipitation components were investigated during two periods.

Masting effect on canopy greenness and climate response on seed production of Fagus grandifolia subsp. mexicana across the Sierra Madre Oriental, Mexico

open access: yesClimate Change Ecology, 2021
Specific proximate mechanisms as climate spatial fluctuations modify the pattern of synchronic reproduction (masting) or seed production at population level in the Fagus genus worldwide.

A comparison of presettlement and modern forest composition along an elevation gradient in central New Hampshire [PDF]

open access: yes, 2011
Tree species composition is influenced not only by edaphic and climatic factors but also by natural and human-caused disturbances. To understand interactions among these influences, we compared forest species composition data from the time of European ...

A first assessment of genetic variability in the longhorn beetle Rosalia alpina (Coleoptera: Cerambycidae) from the Italian Apennines [PDF]

open access: yes, 2018
The Rosalia longicorn (Rosalia alpina) is a strictly protected saproxylic beetle, widely distributed in Central and Southern Europe and mainly associated with ancient beech forests. To improve knowledge about the conservation status of R. alpina in Italy,

Beech wood treated with polyglycerol succinate: a new effective method for its protection and stabilization [PDF]

open access: yes, 2020
This paper deals with an original and non-biocidal chemical treatment consisting of a vacuum/pressure impregnation step of beech wood with a water-borne mixture made from heat-activated condensation of succinic anhydride (SA) and glycerol (G).

Nutritional and environmental factors influence small mammal seed selection in a northern temperate forest

open access: yesEcosphere, 2022
Rodents can influence the succession and assembly of plant communities by preying on and dispersing seeds. Using a seed tray experiment with three common seeds, American beech (Fagus grandifolia), red maple (Acer rubrum), and eastern hemlock (Tsuga ...
