the observed process of change in the species structure of an ecological community over time. Within any community some species may become less abundant over some time interval‚ or they may even vanish from the ecosystem altogether. Similarly‚ over some time interval‚ other species within the community may become more abundant‚ or new species may even invade into the community from adjacent ecosystems. This observed change over time in what is living in a particular ecosystem is "ecological succession"

Investigating the Control Dynamics of an Algae-Brine Shrimp Ecosystem 113437768 Introduction The purpose of this lab is to investigate whether an ecosystem consisting of marine algae and brine shrimp are controlled by top-down or bottom-up mechanisms. The terms top-down and bottom-up in the context of ecology describe which trophic levels are enforcing population pressures on the others. Thus‚ the top-down mechanism of control holds that consumers are responsible for determining the abundance of

Vulnerability and Resilience of Ecosystems * Vunerability is the sensitivity of an ecosystem to cope with stress. * Resilience is the ability of an ecosystem (or a component of an ecosystem) to adapt to a changing environment and to restore function and structure following an episode of natural or human-induced stress. * All ecosystems function in a state of dynamic equilibrium or a continual state of balanced change. *
