Plant species establishment and survival along environmental gradients have commonly been attributed to different environmental niches, life-history and adaptive traits [1]. Effective phenotype adaptation of alder species to extreme soil conditions allows them to form canopy-closed forest vegetation on alluvial and marshland localities. Alder forests represent azonal plant communities developed...

The effect of temperature during short-day (SD) dormancy induction was examined in three boreal tree species in a controlled environment. Saplings of Betula pendula Roth, B. pubescens Ehrh. and Alnus glutinosa (L.) Moench. were exposed to 5 weeks of 10-h SD induction at 9, 15 and 21 degrees C followed by chilling at 5 degrees C for 40, 70, 100 and 130 days and subsequent forcing at 15 degrees C...

Soil respiration (SR) is a major component of ecosystems’ carbon cycles and represents the second largest CO2 flux in the terrestrial biosphere. Soil temperature is considered to be the primary abiotic control on SR, whereas soil moisture is the secondary control factor. However, soil moisture can become the dominant control on SR in very wet or dry conditions. Determining the trigger that make...

Alnus glutinosa (L.) Gaertn. (Betulaceae) est une espèce clé dans certaines formations alluviales et riveraines du continent européen. Au Maroc, elle se trouve en limite méridionale de son aire distribution où représentée par des relictes les zones refuges a migré pendant phases glaciaires Pléistocène. Malgré sa grande valeur patrimoniale, il y très peu données sur répartition l’état peuplement...

Studies conducted in recent years have demonstrated high application potential of thermal remote sensing data environmental analyses. The main goal our studies was to determine the variability tree canopy temperatures using a new sensor which acquires still rarely used spectral range (3.6–4.9 μm). This study on five selected species growing forest and outside forest: Alnus glutinosa, Pinus sylv...
