Pathogenicity of Marssonina betulae on Betula pendula and Betula pubescens

Acta 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.

Free atmospheric CO2 enrichment increased above ground biomass but did not affect symbiotic N2-fixation and soil carbon dynamics in a mixed deciduous stand in Wales [PDF]

, 2011
Through increases in net primary production (NPP), elevated CO2 is hypothesizes to increase the amount of plant litter entering the soil. The fate of this extra carbon on the forest floor or in mineral soil is currently not clear.

Betula mcallisteri sp. nov. (sect. Acuminatae, Betulaceae), a new diploid species overlooked in the wild and in cultivation, and its relation to the widespread B. luminifera

Frontiers in Plant Science, 2023
Taxa are traditionally identified using morphological proxies for groups of evolutionarily isolated populations. These proxies are common characters deemed by taxonomists as significant.

Uncertainty of Forest Biomass Estimates in North Temperate Forests Due to Allometry: Implications for Remote Sensing [PDF]

, 2013
Estimates of above ground biomass density in forests are crucial for refining global climate models and understanding climate change. Although data from field studies can be aggregated to estimate carbon stocks on global scales, the sparsity of such ...
