Trajectoires d’autoéclaircie du Douglas (Pseudotsuga menziesii) en France

Revue Forestière Française, 2016
Les relations taille-densité sont des équations de prédiction du nombre d’arbres vivants en fonction d’une caractéristique moyenne de peuplement. Elles ne sont généralement connues que pour la densité maximum (densité relative RDI égale à 1). Sur la base

Projected Temperature and Precipitation Expand Modeled Distributions of Reynoutria spp. While Modeled Distribution Changes for Ludwigia spp. Are Scenario‐Dependent at Watershed Scales in the Pacific Northwest, USA

River Research and Applications, EarlyView.
ABSTRACT Invasive species can fundamentally alter their introduced habitats by changing natural processes and harming native species crucial to functional ecosystems and human needs. Although the number of potential invasive species is large, the suitability of novel locations to support population establishment is limited by both physical and ...
