Central to the systems ecology approach is the idea that an ecosystem is a complex system exhibiting emergent properties. Systems ecology focuses on interactions and transactions within and between biological and ecological systems, and is especially concerned with the way the functioning of ecosystems can be influenced by human interventions.
The ecosystem approach is a conceptual framework for resolving ecosystem issues. The idea is to protect and manage the environment through the use of scientific reasoning. [1] Another point of the ecosystem approach is preserving the Earth and its inhabitants from potential harm or permanent damage to the planet itself.
Ecosystem-based Adaptation (EbA) describes a variety of approaches for adapting to climate change, all of which involve the management of ecosystems to reduce the vulnerability of human communities to the impacts of climate change such as storm and flood damage to physical assets, coastal erosion, salinisation of freshwater resources, and loss of agricultural productivity.
A structural diagram of the open ocean plankton ecosystem model of Fasham, Ducklow & McKelvie (1990). [1]An ecosystem model is an abstract, usually mathematical, representation of an ecological system (ranging in scale from an individual population, to an ecological community, or even an entire biome), which is studied to better understand the real system.
Sustainable ecosystem management approaches have been used by societies throughout human history. Prior to colonization, indigenous cultures often sustainably managed their natural resources through intergenerational traditional ecological knowledge (TEK). In TEK, cultures acquire knowledge of their environment over time and this information is ...
The components of an ecosystem are interconnected, interrelated, and form a network; consider direct as well as indirect efforts of ecosystem development; An ecosystem has a history of development; Ecosystems and species are most vulnerable at their geographical edges; Ecosystems are hierarchical systems and are parts of a larger landscape;
The bioecological model of development is the mature and final revision of Urie Bronfenbrenner's ecological system theory.The primary focus of ecological systems theory is on the systemic examination of contextual variability in development processes.
Population ecology is a sub-field of ecology that deals with the dynamics of species populations and how these populations interact with the environment. [15] It is the study of how the population sizes of species living together in groups change over time and space, and was one of the first aspects of ecology to be studied and modelled mathematically.
