Size at reproduction is a key aspect of species life history that is relatively understudied for long-lived tropical trees. Here, we quantified reproductive diameter for 31 major timber species across 11 sites in Cameroon, Congo, and Central African Republic. Specifically, we examined whether (1)...
As a consequence of the GEDI reference data used to train the model, each map pixel effectively indicates the largest canopy-top height within a GEDI footprint ( ≈ 25 m diameter) centred at the pixel. Two subtle reasons further impact the effective resolution, compared to a map ...
In conclusion, current tree spatial patterns of trees and their diameter growth are the results of multiple interactions accumulated over the long term with high inertia.doi:10.1002/ecs2.2508Janík, DavidVrška, TomášHort, LiborUnar, Pavel...
to grass stage that looks like a clump of grass 18 inches in diameter and can stay that way for years if not weeded while a root goes down, to this bolting stage with the trunk extending, to sapling and then tree stage.
conditions and forest types, (2) which species were most affected by different natural disturbance agents and (3) are there any differences between pre- and post-disturbance tree species composition (adult trees and recruitment) that may suggest potential vegetation shifts?
The measurement of those canopies is possible only using sensors with a diameter smaller than half the characteristic leaf width, because spatial integration caused by the area of the sensor gives biased power spectra. Smolander (1984) studied the temporal microvariation in a Scotch pine stand by...
Each composite sample was formed by collecting three soil cores using a 5-cm diameter cylinder. The soil cores were placed in sterile Whirl–Pak®bags directly from the cylinder using sterile gloves. To prevent cross-contamination, the cylinders were disinfected with 96° ethanol between samples....
As a result, Appalachian forests became dominated by even-aged stands with few mid-sized and large (>15-m diameter; >175 m2) canopy gaps and infrequent low-intensity fires (Clebsch & Busing, 1989; Nowacki & Abrams, 2008; Raymond et al., 2009). In regions of Appalachia, the fire ...
Four round leaf discs (6 mm in diameter) were randomly punched from each green leaf with a single-hole punch. One pod was selected from the upper, middle, and lower part of each branch at the podding stage and the silique wall was punched. The leaves and silique walls were extracted ...
Stems were sectioned, stem diameter measured, length and diameter measured of any cavities, cavity occupants recorded, and diameter of exit holes for beetles measured. Results/Conclusions We found that the six tree species varied in their potential as a resource for exploitation by canopy ants. ...
