We analysed climate change impacts on the growth and natural mortality of forest tree species and forest carbon (C) balance along an elevation gradient extending from the Pannonian lowland to the West Carpathian Mountains (Central Europe). Norway spruce Picea abies, European beech Fagus sylvatica, and oak Quercus sp. were investigated for 2 future time periods: 2021–2050 and 2071–2100. The peri...
INTRODUCTION – MARTIN L. BLANEY In the process of putting this symposium together with a diverse group of conservation partners, a momentum of purpose and resolve developed that seems to be unprecedented in our region. Upon witnessing our upland oak forests and woodlands slowly degrade in health and vigor through the last decades of our collective careers and then to watch their accelerated dec...
The decline of oak stands is a phenomenon that has been observed since the beginning 20th century in many European countries. It can be caused both with abiotic factors such as drought and fluctuations groundwater levels, well biotic infestations by insects, fungi bacteria. Acute Oak Decline (AOD) an dangerous disease trees which was first XX century. From moment symptoms were noticed, able to ...
U radu se prikazuje pregled dosadašnjih saznanja o Akutnom odumiranju hrastova (AOH), u svijetu opisanom kao AOD (Acute oak decline). Ova polimikrobna bolest je nedavno otkrivena Hrvatskoj (2021. godine) na poluotoku Pelegrin (otok Hvar), gdje stablima hrasta crnike zadnjih nekoliko godina javljaju tipični simptomi: sušenje vrhova krošnje koje prate uzdužne raspukline kore, istodobno ispod kore...
Outbreaks of acute oak decline (AOD) have been documented in England from 2006. Both species of native oaks (Quercus robur and Quercus petraea) are affected. To complement isolation efforts for identification of putative causative biotic agents and increase our understanding of bacteria associated with oak tissue, five sites in England were chosen for this study. Samples of outer bark, inner ba...
