Why are there so many species of plants? Why do some plants thrive, while others don't?Ecologist Noelle Beckman of Utah State University and her colleagues explore these questions in new fin...
In a study recently published in Sensors, Saint Louis University researchers paired satellite imaging data with machine learning techniques to map local tree species and help manage the health of urba...
The new method for evaluation of tree populations presented here is based on a correlation analysis within a set of dendrometric variables. The correlation analysis is carried out for each population...
Drought stress in tropical dry forests is thought to result in greater asexual regeneration via vegetative sprouting (e.g., basal, root, and branch layering) than occurs in moister tropical forests. ...
Premise of the study : Elucidating the factors that determine the abundance and distribution of species remains a central goal of ecology. It is well recognized that genetic differences among indivi...
Generalized additive models were tested using three types of smoothing functions as an alternative for modelling the height curve. The models were produced for 23 forest stands of Norway spruce (Pic...
Sample trees were taken for analyses from an 18-years-old blue spruce stand growing in the summit part of the Jizerské hory Mts. (Czech Republic). The sample trees were measured and dry matter and nut...
The Bohemian Forest Mts. (Šumava) were exposed to heavy atmospheric pollution in the last century. A possible negative effect of atmospheric pollution on tree physiology has been studied using th...
Micro-hardness was used for the study of wood structure (Norway spruce) in the line perpendicular to tree rings (radial surface). The steel indentor 0.25 mm in diameter with flat head was used for thi...
Premise of the study : Seabirds often cause signifi cant changes to soil properties, and seabird-dominated systems often host unique plant communities. This study experimentally (1) examined s...
Tree architecture represents various ecological and physiological functions, such as acquisition of light, spatial distribution of vegetative and reproductive organs and pathway for water and nutrient...
