The understanding of spatial distribution patterns native riparian tree species in Europe lacks accurate models (SDMs), since forest habitats have a limited extent and are strongly related to the associated watercourses, which needs be represented environmental predictors. However, SDMs urgently needed for adapting management climate change, as well conservation restoration ecosystems. For such...

Quality tree species information gathering is the basis for making proper decisions in forest management. By applying new technologies and remote sensing methods, very high resolution (VHR) satellite imagery can give sufficient spatial detail to achieve accurate species-level classification. In this study, influence of pansharpening WorldView-3 (WV-3) on classification results three main (Querc...

Alder wood (Alnus glutinosa L.) was steamed with a saturated steam-air mixture at temperature of t = 95 °C, or steam 115 °C and 135 to obtain pale brown colour, light red-brown colour dark brown-grey colour. Subsequently, samples unsteamed alder were irradiated UV lamp in Xenotest Q-SUN Xe-3-HS after drying order test the stability wood. The change surface evaluated by means measured values on ...

While the dominant ectomycorrhizal (ECM) fungi in most temperate and tropical forests have low host specificity, a commonly cited exception to this pattern is the ECM fungal community associated with the host genus Alnus. In this chapter, we discuss multiple hypotheses that have been put forth to explain the specificity of the Alnus ECM symbiosis and consider their strengths and weaknesses in l...

The name Alnus viridis (Chaix) DC., based on Betula viridis Chaix (1785), has traditionally been attributed to green alders although it is based on a later basionym. Alnus alnobetula (Ehrh.) K. Koch based on Betula alnobetula Ehrh. (1783) is the correct name for green alders. In light of the increasing use and recognition of the name Alnus alnobetula (Ehrh.) K. Koch in the literature. I herein ...

BACKGROUND/AIMS Recently, new palaeoecological records supported by molecular analyses and palaeodistributional modelling have provided more comprehensive insights into plant behaviour during the last Quaternary cycle. We reviewed the migration history of species of subgenus Alnus during the last 50,000 years in Europe with a focus on (1) a general revision of Alnus history since the Last Glaci...
