aengine number 引擎数字[translate] aHowever, little is known of the true biodiversity of Kingdom Fungi, which has been estimated at around 1.5 million species, with about 5% of these having been formally classified. 然而,一点被知道王国真菌真实的生物多样性,在1.5百万个种类前后估计,与正式被分类的...
Do you know that forests cover an estimated 38 percent of the total land surface of the European Union (EU)? And that these extensive areas covered with trees and underbrush need to be protected so they can continue to do good for the environment for the next generation? Now the EU has...
These factors represent the number of trees per hectare that each measured tree represents in relation to the subplot radii (Jiménez et al., 2017). In addition, the percent cover and mean height of understory shrub species were measured in the 10-m-radius subplot (Fig. 3). Allometric ...
In order to calculate the total CO2 captured and emitted by the REPSA, we averaged the number of individuals for each species in eight quadrants. The results (six, seven and 79 for B. cordata, S. praecox, and E. gibbiflora, respectively) were then extrapolated to the REPSA. We also ...
on the surface (DSSR), air temperature (T2M), and relative humidity (RH2M) at 2 meters above the surface, and three variables derived from LAI to indicate plant functional type (PFT): the minimum (LAI_MIN) and maximum (LAI_MAX) of LAI in a year, and the number of LAI larger than...
In the United States alone it kills an average of one person every day. The safest place to be in case of an electrical storm is in a closed car. Outside, one should go to low ground and should not get under trees. Also, one should stay out of water and away from metal fences. ...
It has been shown that the station-based TLR may not be optimal for downscaling when a small number of weather stations are insufficient to represent spatial variability at the scale of a grid block. Recently, based on the strong correlation and consistency between air temperature and remote ...
For the third method, we estimated LAI as a function of tree diameter and species-specific coefficients, based on destructive sampling of a small number of trees of four tree species [21]: Engelmann spruce (Picea engelmanniiParry), subalpine fir (Abies lasiocarpa(Hook.) Nutt.), lodgepole pine...
Post-fire landscapes where trees have fallen, forests that have experienced major insect, disease, or windthrow events, post-logging areas with a high concentration of slash, and even just forests with high loads of coarse woody debris are all very challenging and slow to walk through. To ...
