Understanding Ecological Dynamics: Logistic Growth, Adaptive Cycles, and Landscape Stability
This document explores key ecological concepts illustrated in figures from Chapter 3, including logistic population growth curves and their relationship with Maximum Sustainable Yield (MSY). It discusses the hierarchy of processes determining tree density, adaptive cycles featuring growth and renewal phases, and landscape stability in various ecological states. Additionally, it covers the development of non-analogue communities in response to changing climates and presents the process of Strategic Adaptive Management, essential for conserving and managing ecosystems effectively.

Figures from Chapter 3
Figure 3.1 (a) A graphical representation of the logistic population growth curve and its relationship with maximum sustainable yield (MSY). (b) The inflection...(the average ‘carrying capacity’).
Figure 3.2 A hierarchy of processes determine tree density in...the mechanisms and constituent parts from which higher-level systems emerge. Modified from Gillson (2004b).
Figure 3.3 Adaptive Cycles. Four distinct phases have been identified: 1 growth or exploitation (r)... leading to renewal. From the Resilience Alliance (www.resalliance.org/570.php).
Figure 3.4 Landscape stability in alternative steady states. Superimposed...landscape recovery. From Dearing (2008). (See Plate 3.4 for a colour version of this image.)
Figure 3.5 A diagram illustrating how non-analogue communities can develop over time with changing climate. The light...the area. After Williams & Jackson (2007).
