Long term variation of leaf abundance in a northern hardwood forest

Ecological Indicators, 2022
Leaf abundance of trees plays a dominant role in energy, water and nutrient flux of forest ecosystems, in defining the habitat structure of entrained biota and in mediating interspecific competition among tree species.

First Report of Beech Bark Disease in Michigan

Plant Disease, 2001
Beech bark disease of American beech (Fagus grandifolia) is caused by the interaction of an introduced scale insect (Cryptococcus fagisuga) and the native fungus Nectria galligena, or N. coccinea var. faginata, which is thought to be introduced. Infestations of the insect precede development of the disease, and N.

Influence of individual tree characteristics, spatial structure and logging history on tree-related microhabitat occurrence in North American hardwood forests

Forest Ecosystems, 2021
Background Tree-related microhabitats (hereafter, “TreMs”) are key components of forest biodiversity but they are still poorly known in North American hardwood forests.

Beech bark disease and archaeological crop marks [PDF]

Nature, 1979
THE presence of ‘crop marks’ in aerial photographs is frequently used to detect archaeological features. These marks are produced by differences in plant size or colour which are related to the characteristics of the soil overlying or comprising the man-made feature.

Development of beech necrotic disease in the growing phase of maturing stand under air pollution stress

Journal of Forest Science, 2005
The paper compares the state of the necrotic disease of beech stem bark on three research plots in 2004 with 1995. The investigated objects were three research plots of beech in the growing phase of maturing stand in Central Slovakia subjected to ...

Development of necrotic disease and health condition of trees of selective quality in a systematically tended beech pole-stage stand

Journal of Forest Science, 2003
We compare the results of observations of bark necrotic disease and defoliation of beech assimilatory organs carried out in 1996 and 2000. A systematically managed, 53-year old beech pole-stage stand in Central Slovakia was chosen as an object of our ...

Exploiting Native Biodiversity for Invasive Species Management: The Case of Exorista larvarum as a Natural Enemy of the Invasive Box Tree Moth Cydalima perspectalis

Entomologia Experimentalis et Applicata, EarlyView.
The investigations evaluated the performance of the native parasitoid Exorista larvarum (L.) on last instar Cydalima perspectalis (Walker) larvae, using the factitious host Galleria mellonella (L.) as a control. Laboratory bioassays were conducted using no‐choice and choice (1:1 and 5:5) experimental designs.

The tree‐parasitic fungus Cryphonectria carpinicola discovered on European chestnut and European hornbeam in Azerbaijan

EPPO Bulletin, EarlyView.
Abstract The ascomycetous fungus Cryphonectria carpinicola is typically found in its asexual form on the European hornbeam, and its sexual state has only recently been discovered in deadwood of different Carpinus species in Japan. Recently, this fungus has been added to the EPPO Alert List due to its increasing incidence in the EPPO region and a ...
