The use of statistical and mathematical models for sustainability-related problems has a long history, paralleling the evolution of computing technology itself. A notable example is the early attempts at climate modeling, which were constrained by the limited computing resources available at the time, necessitating simplified models.
Document Object Models ("DOM tree") of XML and HTML documents; Search trees store data in a way that makes an efficient search algorithm possible via tree traversal. A binary search tree is a type of binary tree; Representing sorted lists of data; Computer-generated imagery: Space partitioning, including binary space partitioning; Digital ...
TreeHugger is a sustainability website that reports on news, and other subjects like eco-friendly design, homes, and gardens. It was rated the top sustainability blog of 2007 by Nielsen Netratings, [1] and was included in Time Magazine's 2009 blog index as one of the top twenty-five blogs. [2] The website boasts "over 100 expert writers."
Following human migration and population growth, species extinctions have progressively increased to a rate unprecedented since the Cretaceous–Paleogene extinction event. [citation needed] Known as the Holocene extinction event this current human-induced extinction of species ranks as one of the world's six mass extinction events. Some ...
Ecological classification or ecological typology is the classification of land or water into geographical units that represent variation in one or more ecological features. . Traditional approaches focus on geology, topography, biogeography, soils, vegetation, climate conditions, living species, habitats, water resources, and sometimes also anthropic factors.
Species evenness is the relative number of individuals of each species in a given area. [1] Species richness [2] is the number of species present in a given area. Species diversity [3] is the relationship between species evenness and species richness. There are many ways to measure biodiversity within a given ecosystem.
Ecosystems are complex and ecological indicators can help describe them in simpler terms that can be understood and used by non-scientists to make management decisions. For example, the number of different beetle taxa found in a field can be used as an indicator of biodiversity. Many different types of indicators have been developed.
The Classification Tree Method is a method for test design, [1] as it is used in different areas of software development. [2] It was developed by Grimm and Grochtmann in 1993. [3] Classification Trees in terms of the Classification Tree Method must not be confused with decision trees. The classification tree method consists of two major steps ...
