The 'predator landscape' outside the fence is obvious from its generally healthy mature trees, continuous canopy tree recruitment and higher ground layer plant cover.
Several dynamic, thermal, and water vapor conditions including the layered structure of thermal inversion, the increase of temperature in the ground layer after sunrise, and the vertical transmission of heat, momentum, and water vapor caused by turbulent mixing have been found that trigger to dense fog [1, 10, 11].
However, the distribution of woody cover was variable with some areas having high cover and other areas with low cover but high stem density where woody species have not formed a canopy over the ground layer. This study is based on baseline data from permanent vegetation sample plots to be used for tracking restoration progress following shrub and sapling removal.
Titanium white was identified in an underlayer, the ground layer applied before any of the paint layers.
The antenna ground layer is connected directly with the system ground plane through the addition of grounded vias distributed on all four side-walls (where the number of the vias will be discussed in following part).
Analysis of the herbaceous layer and ground layer data was conducted using Non-metric multidimensional scaling (NMS), Multiple Response Permutation Procedure (MRPP) and Indicator Species Analysis (ISA).
TEPCO has denied the faults are active under existing guidelines, but, for example, the beta fault could be categorized as active under the new definition because it has displaced a ground layer including volcanic ash dating back 240,000 years.
According to Samtec, "Single-ended traces are referenced to an adjacent ground layer. ...
The filter consists of two layers, i.e., the top microstrip layer (MSL) and the bottom defected ground layer (DGL).
In August 2002, vegetation of the ground layer in each of the five sites was sampled by using 20 line transects that were 5 m long; the end point of each transect was placed on 20 of the permanent stakes that were used in the overstory transects (n 5 100 quadrats/ site).
The presence of loose material below the ground layer was ignored.
Ground layer vegetation is sporadic and is primarily poison ivy and green briar.
