The Miocene Bükkábrány Fossil Forest in Hungary – field observations and project outline [PDF]
, 2008 The oldest, standing forest preserved as wood has been found at Bükkábrány, Hungary. An open-pit mine working Upper Miocene (Pannonian) lignite revealed sixteen stumps, 1.8 to 3.6 m diameter at base, preserved up to 6 m height, standing on top of the ...

A dendroecological study in a declining oak coppice stand [PDF]
Annales des Sciences Forestières, 1996 L'etude a concerne un taillis mixte (Quercus cerris L predominant), âge de 30 ans, situe pres de Tolfa, Rome, Italie. La zone est marquee par un surpâturage de bovins et l'absence de toute intervention sylvicole. Pour evaluer l'importance des differents facteurs relies au deperissement, la situation phytopathologique du peuplement a ete comparee avec ...

Journal of Ecology, Volume 113, Issue 11, Page 3141-3158, November 2025.Diameter growth is an important and good indicator of forest carbon production. However, size‐related changes in wood density, which are usually neglected, are critical for accurate short‐ and long‐term carbon assessments, especially in tropical humid sites.

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

Ecology and Evolution, Volume 15, Issue 8, August 2025.This meta‐analysis on intraspecific variation in European trees studied the frequency of provenance variation, provenance–environment interaction, clinal variation along the climate of origin or transfer distance. While identifying trait group specific patterns of variation, research gaps have been identified in terms of age and geographical ...

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