Moreover, the steepest slopes of mountain sites determines more frequent small-scale disturbances than coastal sites with gentle slopes (Roig 1998) generating greater microenvironmental heterogeneity.
The model reproduces historical aspects of New Orleans economic development and levee construction and the filtering of frequent small-scale floods at the expense of large disasters.
In much of the world, the spatial scale of natural disturbance regimes can be represented by a J-shaped size frequency distribution, i.e., a combination of frequent small-scale and fewer large-scale disturbances (Veblen et al. 1981; Seymour and Hunter 1999; Shorohova et al. 2009; Yasuda et al. 2013).
For example, since 2007, a group of volcanologists from the Instituto Geofísico de la Escuela Politécnica Nacional de Quito (2012) has installed about 30 ash-collection receptacles around Tungurahua volcano to improve volume estimations of frequent, small-scale tephra emissions (Bustillos and Mothes2010).
Civilian populations continue to endure frequent small-scale attacks by armed groups and armed forces.
These "prescribed burns" need to be frequent and on a small scale.
Our findings demonstrate the importance of vegetation diversity (e.g., mature pine, mixed pine/hardwoods, hardwoods, agriculture/food plots, shrub-scrub) for bobcats in a forested landscape managed by frequent (≤3 years) and small scale (< 40 ha) fires.
With the average patch size burned on our study area < 40 ha in size, our findings suggest that small scale (< 40 ha) frequent fires (≤ 3 years) may have minimal influence on bobcat habitat selection.
While the threat of pollution from the Islamic State's small scale oil productions — and their frequent destruction — is smaller relative to the oil fires set in Iraq during the first Gulf War, PAX reported that Syria's heavy crude oil is higher in potentially noxious substances, making it "a particularly problematic soil and water contaminant".
Events such as single nucleotide polymorphisms (SNPs), that affect only one nucleotide at a time, are said to be small scale events, and are more frequent than large scale events [ 1].
On this small scale, familiar local features can guide bees towards frequent foraging routes or directly to the hive [36].
