The most recent climate change scenarios show that Southern and Eastern Europe will be affected by a significant increase in temperature drought frequency the end of 21st century. Romania has already recorded very high temperatures long periods over decades, regions being south, west east country. Considering successful forest management requires suitable species high-quality reproductive mater...
Radar backscatter from forest canopies is related to forest cover, canopy structure and aboveground biomass (AGB). The S-band frequency (3.1–3.3 GHz) lies between the longer L-band (1–2 GHz) and the shorter C-band (5–6 GHz) and has been insufficiently studied for forest applications due to limited data availability. In anticipation of the British built NovaSAR-S satellite mission, this study ev...
Alien invasive species can affect large areas, often with wide-ranging impacts on ecosystem structure, function, and services. Prunus serotina is a widespread invader of European temperate forests, where it tends to form homogeneous stands and limits recruitment of indigenous trees. We hypotesized that invasion by P. serotina would be reflected in the nutrient contents of the native species' le...
Aeolesthes sarta (Solsky 1871) (Coleoptera: Cerambycidae) is a polyphagous longhorned beetle species that primarily damages broadleaved tree species. This pest distributed in the western and northern regions of Pakistan, where it caused serious damage to Populus spp. plantations. However, growth dispersal patterns insects pests are changing due climate change. Modeling range expansion or contra...
In an Irish context, and indeed in Northern Europe, one of the most important allergenic pollen types is birch (Betula spp.). Thus, forecasts such atmospheric are tools for helping patients suffering from rhinitis and/or atopic asthma to avoid high ambient concentrations manage their symptoms. This work aims improve knowledge about spatial temporal variations distribution trees airborne Betula ...
The main objective of this study is to analyze the spatial and temporal variability gross net primary production (GPP NPP) in Peninsular Spain across 15 years (2004–2018) determine relationship those carbon fluxes with precipitation air temperature. A time series daily GPP, NPP, mean temperature, monthly standardized index (SPI) at 1 km resolution conducted ecosystem status adaptation changing ...
Land cover plays a major role in many biogeochemical models that represent processes and connections with terrestrial systems; hence, it is a key component for public decisions in ecosystems management. The advance of remote sensing technology, combined with the emergence of new operational products, offers alternatives to improve the accuracy of environmental monitoring and analysis. This work...
Quantitative relationships between stand indices and carbon dioxide (CO2) stocking are missing in the evergreen broadleaved forests (EBLFs) in eastern China and this hinders to estimate carbon (C) budget in the subtropical region. We determined the vegetation-soil C pool and CO2 stocking using stand indices [diameter at breast height (DBH), total height (H) and wood density] in Schima superba d...
