WebSep 29, 2010 · Ecological thresholds are characterized in the literature as abrupt changes in a response variable as a consequence of continuous change in an independent variable (Muradian 2001, Groffman et al. 2006, Dodds et al. 2010). The threshold is defined as the point where this function shows a change in the value (or sign) of the slope.

Webthe development of ecological thresholds that is based on the concept of ecological resilience. Ecological resilience describes the degree of ecosystem modification that is required before the system begins to reorganize around an alternative set of reinforcing processes (Peterson et al. 1998; Gunderson 2000). WebIdentifying critical thresholds in species response to habitat alteration is a promising approach to address ecological questions and to provide answers that are meaningful from a management perspective. This approach is not a new one as it is very.
Ecological threshold is the point at which a relatively small change or disturbance in external conditions causes a rapid change in an ecosystem.
