BrowsedBetula pubescenstrees are not carbon‐limited [PDF]

open access: yesFunctional Ecology, 2008
33 páginas, 5 figuras, 3 tablas. 1. Slower growth after repetitive browsing of young trees has been attributed to a carbon (C) limitation, but data from long-term studies are lacking. To determine if repeated summer browsing causes a C (source) limitation in trees in the long-term, we analysed the non-structural carbohydrate (NSC) and ...

Breeding increases the efficacy of Chondrostereum purpureum in the sprout control of birch. [PDF]

open access: yesPLoS ONE, 2015
We tested whether the pairing of selected isolates could be used to increase the efficiency of a decay fungus Chondrostereum purpureum (Pers. Ex Fr.) Pouzar to control hardwood sprouting in Finland. We paired C.

Pathogenicity of Marssonina betulae on Betula pendula and Betula pubescens

open access: yesActa Silvatica et Lignaria Hungarica, 2007
Studies were undertaken to investigate whether Marssonina betulae is a causal agent of dieback of young birch in Scotland. Marssonina betulae was inoculated onto shoots of B. pendula and B. pubescens and symptoms monitored over several seasons. On B. pendula, but not B.

Spatial and temporal dynamics of growth of woody plant species (birch and willows) on the foreland of a retreating glacier in southern Iceland

open access: yesEcological Processes, 2021
Background The forelands of retreating glaciers are invaluable natural laboratories in which to explore the processes of primary succession. Numerous studies have been conducted on foreland chronosequences to identify temporal and spatial trends of the ...

Similarity of Betula borysthenica Klokov with intraspecific taxa of Betula pubescens Ehrh.

open access: yesChornomorski Botanical Journal, 2013
The article is on the new data about taxonomical status of the endemic species Betula borysthenica Klokov, which is listed in The Red Book of Ukraine. The data were obtained by chemotaxonomic, morphological and molecular genetic approaches. Based on the results of gel-electrophoresis of soluble seed storage proteins and morphology of seedlings some ...

Forecasting probability distributions of forest yield allowing for a Bayesian approach to management planning

open access: yesSilva Fennica, 2001
Probability distributions of stand basal area were predicted and evaluated in young mixed stands of Scots pine (Pinus sylvestris L.), Norway spruce (Picea abies (L.) Karst.) and birch (Betula pendula Roth and Betula pubescens Ehrh.) in Sweden.
