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.
Species distribution modelling (SDM), also known as environmental (or ecological) niche modelling (ENM), habitat modelling, predictive habitat distribution modelling, and range mapping [1] uses ecological models to predict the distribution of a species across geographic space and time using environmental data. The environmental data are most ...
The concept was applied to planning nature preserves, which are effectively islands in a sea of human-generated or dominated habitat. Simberloff and Abele argued that even though smaller reserves will hold fewer species than larger reserves, a series of small reserves could theoretically hold (protect) as many species as a single large reserve.
Gap analysis is a tool used in wildlife conservation to identify gaps in conservation lands (e.g., protected areas and nature reserves) or other wildlands where significant plant and animal species and their habitat or important ecological features occur.
Reserve design is the process of planning and creating a nature reserve in a way that effectively accomplishes the goal of the reserve. Reserve establishment has a variety of goals, and planners must consider many factors for a reserve to be successful. These include habitat preference, migration, climate change, and public support.
The World Network of Biosphere Reserves (WNBR) of the MAB Programme consists of a dynamic and interactive network of sites. It works to foster the harmonious integration of people and nature for sustainable development through participatory dialogue, knowledge sharing, poverty reduction, human well-being improvements, respect for cultural values and by improving society's ability to cope with ...
This equation has frequently been used for designing reserve size and placement (see SLOSS debate). [12] The most common version of the equation used in reserve design is the formula for inter-island diversity, which has a z-value between 0.25 and 0.55, [ 13 ] meaning protecting 5% of the available habitat will preserve 40% of the species present.
Ecological overshoot expressed in terms of how many Earths equivalent of natural resources are consumed by humanity each year. Ecological overshoot is the phenomenon which occurs when the demands made on a natural ecosystem exceed its regenerative capacity. Global ecological overshoot occurs when the demands made by humanity exceed what the ...
