Applying taper function models for black locust plantations in Greek post-mining areas.

A key process in forest management planning is the estimation of tree volume and, more specifically, merchantable volume. The ability to predict the cumulative stem volume relative to any upper stem diameter on standing trees or stands is essential for forest inventories and the management of forest resources. In the 1980s, the Hellenic Public Power Corporation (HPPC) started the rehabilitation of lignite post-mining areas in Greece by planting mainly black locust (Robinia pseudoacacia, L.

Physiological and phenological adjustments in water and carbon fluxes of Aleppo pine forests under contrasting climates in the Eastern Mediterranean.

The ability of plants to adjust to the adverse effects of climate change is important for their survival and for their contribution to the global carbon cycle. This is particularly true in the Mediterranean region, which is among the regions that are most vulnerable to climate change. Here, we carried out a 2-year comparative ecophysiological study of ecosystem function in two similar Eastern Mediterranean forests of the same tree species (Pinus halepensis Mill.

Within-forest stand (or formation, or plot) and between-forest stand (or formation, or plot) biodiversity indices.

The idea of entropy, which has its roots in information theory and proposes that one may measure the degree of uncertainty associated with the prediction of bits and pieces of information, has been widely used by biologists and ecologists for decades to define biological diversity. For ecologists, the core of the issue is whether or not two species' distribution taken from the same habitat are the same or distinct. The Shannon index and Simpson diversity are well-known in ecology; however, the non-linearity of these indices may cause a misinterpretation of the underlying diversity, as shown by Lou Jost (2006) and others.

Diurnal photosynthetic performance of two oak species from two provenances in a Mediterranean and a central European common garden.

Oaks may contribute to the stabilization of European forests under climate change. We utilized two common gardens established in contrasting growth regimes, in Greece (Olympiada) and Germany (Schwanheim), to compare the diurnal photosynthetic performance of a Greek and an Italian provenance of two Mediterranean oaks ( and ) during the 2019 growing season. Although the higher radiation in the southern common garden led to a strong midday depression of chlorophyll fluorescence parameters (maximum quantum efficiency of PSII, performance index on absorption basis), comparable light-saturated net photosynthetic rates were achieved in both study areas.
