Woody Plants Affected by Ungulates in Winter Period, Impacts and Bark Renewal
Ekológia (Bratislava), 2015 Due to biotope fragmentation and changes in landscape structure, opportunities for forest animals to migrate and obtain food are diminishing, especially during extreme winter conditions. The main objective of this research was an assessment of ungulates,

Dieback of Fraxinus excelsior [PDF]
, 2013 Ash dieback caused by Hymenoscyphus pseudoalbidus (anamorph Chalara fraxinea) is a disease that has emerged during the past twenty years. It was first observed in Poland and has expanded over most of the distribution area of European ash (Fraxinus excelsior) in Europe. This thesis comprises four scientific papers.

Canditate metabolites for ash dieback tolerance in Fraxinus excelsior
Journal of Experimental Botany, 2020 AbstractAsh dieback, a forest epidemic caused by the invasive fungus Hymenoscyphus fraxineus, threatens ash trees throughout Europe. Within Fraxinus excelsior populations, a small proportion of genotypes show a low susceptibility to the pathogen.

Gelatinous Fibres in Ash (Fraxinus excelsior L.) [PDF]
Nature, 1965 TENSION wood in dicotyledonous trees and shrubs is recognized by the presence of gelatinous fibres. These fibres have an inner layer, composed almost entirely of cellulose (the G-layer), which may replace either the S3 or both the S3 and S2 layers of the secondary wall of the fibres.
