Climate change impact on a mixed lowland oak stand in Serbia

open access: yesAnnals of Silvicultural Research, 2015
Climatic changes and bad environmental conditions may lead to forests vitality loss and even mortality. This is the reason why increased sanitary felling operations were performed in mixed oak forests in northern Serbia in 2013 in order to solve the ...

Post-drought Resilience After Forest Die-Off: Shifts in Regeneration, Composition, Growth and Productivity

open access: yesFrontiers in Plant Science, 2018
A better understanding on the consequences of drought on forests can be reached by paying special attention to their resilience capacity, i.e., the ability to return to a state similar to pre-drought conditions. Nevertheless, extreme droughts may surpass

History of Tree Growth Declines Recorded in Old Trees at Two Sacred Sites in Northern China

open access: yesFrontiers in Plant Science, 2017
Old forests are an important component in sacred sites, yet they are at risk of growth decline from ongoing global warming and increased human activities. Growth decline, characterized by chronic loss of tree vigor, is not a recent phenomenon.

MAIDEN: a model for analyzing ecosystem processes in dendroecology [PDF]

open access: yesCanadian Journal of Forest Research, 2004
Ecophysiological and dendroecological data from a temperate sessile oak (Quercus petraea (Matt.) Liebl.) stand in Belgium were used to develop and parameterize a dendroecological process-based model. The purpose of this model is to serve as a tool for exploring the relationship between climate variability and tree growth based on dendro ecological ...

Natural Disturbances Regime as a Factor of Korean Pine-Broadleaved Forest Stand Shaping in the South of the Russian Far East [PDF]

open access: yesЖурнал Сибирского федерального университета: Серия Биология, 2015
Using dendroecological approach we reconstructed disturbance history of a mixed Korean pinebroadleaved stand in the south of the Russian Far East. Our results show that during the last two centuries there were no mass disturbances, which may lead to ...

Arctic amplification causes earlier onset of seasonal tree growth in northeastern Siberia

open access: yesEnvironmental Research Letters
Although recent warming affects the high-northern latitudes at an unprecedented rate, little is known about its impact on boreal forests because in situ observations from remote ecosystems in Siberia are sparse.
