Molly Matteson, a wildlife biologist with the US Center for Biological Diversity, observes that the group has "petitioned for other bird species that have climate change as one of their threat factors.
The changes of consumption behavior and the liberation of the marketplace are classified as threat factors.
To act in security, therefore, does not just mean to take shelter from illegitimate offensive actions, but also to eliminate or diminish the risk or threat factors of the values mentioned above.
Prior perception of personal risk, the risk level (hazardousness) commonly associated with an area, action by public authorities, housing protective quality, and storm-specific threat factors were found to largely account for evacuation behavior.
But urbanization, an accelerated technological development and an increased attention to the environment are expected to work either as opportunity factors or threat factors while depending on the innovations of nuclear technology.
Unfavourable habitat condition was predicted by threat factors such as lack of management and high incidence of arable or improved grassland around patches of calcareous grassland, indicating nutrient enrichment and habitat degradation.
Although population size is unknown, relatively low number of individuals observed in almost all localities (on average less than five individuals were observed at each locality), but particularly at gueltas, suggests that the actual number of crocodiles present is small, which stresses the vulnerability of these habitats to threat factors.
A more detailed prioritization of taxa and geographic areas for collection can be achieved by including in the analysis predictive threat factors, such as climate change or habitat destruction, or by adding additional prioritization filters, such as the degree of relatedness to cultivated species (i.e. ease of use in crop breeding).
