Ds and Dc are the 'superparamagnetism' and 'critical' size thresholds.
The algorithm was constrained to include peatlands containing habitat patches that met specific size thresholds.
Time and size thresholds were changed for the LeftBag sequence, according to the geometry and challenge of the scene.
National forest inventory systems (NFIs), if existing at all, differ considerably in design, size thresholds, definitions, estimation methods, census interval, and importantly, in data access policy.
The simple atomic model qualitatively reproduces experimental findings when scaled up to sufficiently large spatial dimensions, and provides insight into the finite size thresholds separating nanoscale from microscale behaviour.
Remnant size thresholds, below which biodiversity declined rapidly, were observed at approximately 4 ha for bird and frog species richness and approximately 2 ha for plant and fungal species richness.
Stamps (2000) proposed effect size thresholds that are adapted to evaluate judgments of scenic impact, effect on enjoyment and continued use of scenic resources affected by ten proposed wind energy project in the State of Maine, USA.
Thus, particle size predictor make up to 70% of the precipitation variables, and describe various aspects of the particle size distribution, notably the median size and the percentage of particles above and below specific size thresholds.
Although acquiring only larger parcels may make sense financially, it does not result in adequate habitat representation because the spatial distribution of parcels is such that the lower elevation oak woodland and mid-elevation conifer forests tend to be on smaller parcels, which fall below the larger size thresholds and the resulting potential reserve areas are fragmented.
Many conservation planners want to set minimum PA size thresholds, as small PAs are less viable and more expensive to manage, but this can only be achieved with existing software packages by repeatedly reducing the fragmentation levels of the PA system until every PA meets the threshold.
Individual cells were discriminated by incorporating the shape and size thresholds, providing, together with the color thresholds, actual cell counts.
