However, in countries where industry monitoring is less complete or for landscapes covering political units with incompatible monitoring systems, inventory-calibrated satellite maps may be used to estimate not only the position but the magnitude of harvests [29].
In an eco-genetic model of a species with paternal care, the smallmouth bass Micropterus dolomieu, Dunlop et al. (2007) found that including a survival advantage for the offspring of large males significantly reduced the magnitude of harvest-induced evolution.
Differences in map surfaces of predicted volume over time were used to identify the location, timing, and magnitude of harvests in Ravalli County from 1985 to 2005 in approximately 2-year intervals.
However, in countries where industry monitoring is less complete or for landscapes covering political units with incompatible monitoring systems, inventory-calibrated satellite maps may be used to estimate not only the position but the magnitude of harvests [ 29].
The magnitudes of harvest-induced evolutionary changes in probabilistic maturation reaction norms (PMRNs) found in our study were broadly consistent with qualitative predictions made in the existing literature on harvest-induced maturation evolution.
Measures such as the magnitude of bushmeat harvest [30], coral reef habitat quality [31], seagrass loss [32], freshwater habitat degradation [33], illegal fishing [34], invertebrate threat patterns [35], and some forms of greenhouse gas emission [36] were simply not available at the global scale of investigation.
We conducted further analyses in an attempt to identify variables controlling the magnitude of post-harvest treatment responses.
Model rules automatically determine the frequency and magnitude of mowing (harvests) events in each grid cell [39], which simulates a potential (maximum) productivity.
The post disturbance pulse of Rh and negative NEP is of greater magnitude in the case of harvest but of greater duration in the case of fire because the proportion of the biomass actually burned in a wildfire is often small [51] and standing dead trees (snags) decay relatively slowly [13].

Given the magnitude of the tree harvesting and changes in the environment, Mr. Wear said, "sustainability is not a foregone conclusion.
