Coarse woody debris (CWD; i.e. downed limbs and boles) serves numerous ecosystem functions, which vary according to the degree of decay. CWD decay is often described using five categories based on readily observed physical characteristics ranging from freshly fallen (Class I) to advanced decay with ...

Dendrochronological investigations on subfossil European ash (Fraxinus excelsior L.) wood found in two bogs of Western Lithuania are presented. Radiocarbon dating has revealed that Fraxinus grew in the Middle and Late Holocene, from approximately 4700 BC to 1500 BC. It is proposed that the growth...

Emerald ash borer (EAB) (Agrilus planipennis Fairmaire), is a non-native beetle responsible for widespread mortality of several North American ash species (Fraxinus sp.). The objective of this study was to examine the effects of climate on the radial growth of white ash (Fraxinus americana)...

Laughery Bluff and Dogwood Nature Preserves are two old-growth forest stands in southeastern Indiana (Ripley County). The stands, which are part of Versailles State Park, are unique in that their stem structure, composition, and dynamics have been monitored repeatedly over many decades. The goals...

Pest preference and subsequent susceptibility of a host individual is likely related to previous growth patterns in that host. Emerald ash borer (Agrilus planipennis Fairmaire) is a pestiferous beetle introduced to North America from Asia. While all species of ash are susceptible to attack, some...

We counted the intra-annual density fluctuations (IADFs) of oak (Quercus robur) tree rings sampled in a deciduous broadleaf forest near Kozelsk (Kaluga region) in the Ugra National Park, Central Russia. Three sites in the same forest massif were sampled. We also sampled ash (Fraxinus excelsior)...

The gradual increase in temperature over the last few decades is one of the major consequences of global change. It is also projected that drought frequency and intensity in the Mediterranean region will increase, promoting changes in plant responses to environmental conditions and ultimately...

Tree-ring analysis is widely used in many different fields of science. Among others, information carried by annual tree rings allows determining the rates of environmental changes and the timing of events. The analysis of the tree rings requires prior detection of tree-ring boundaries which is...

Dendrochronological investigations on subfossil Fraxinus and Quercus wood found in the Kegai mire in Western Lithuania are discussed. Radiocarbon dating has revealed that the trees grew in the middle and late Holocene (Fraxinus approximately from 4700 to 1500 BC and Quercus from 3400 to 2300 BC)....
