Some species-focused databases attempt to compile comprehensive data about particular species , while others focus on particular species attributes, such as checklists of species in a given area (FEOW) or the conservation status of species (CITES or IUCN Red List). Nomenclators act as summaries of taxonomic revisions and set a key between ...
Although biodiversity loss can be monitored simply as loss of species, effective conservation demands the protection of species within their natural habitats and ecosystems. Following human migration and population growth, species extinctions have progressively increased to a rate unprecedented since the Cretaceous–Paleogene extinction event.
[3] [4] BEC is termed an ecosystem classification as the approach integrates site, soil, and vegetation characteristics to develop and characterize all units. BEC has a strong application focus [ 5 ] and guides to classification and management of forests , grasslands and wetlands are available for much of the province to aid in identification ...
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."
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.
A Green Score of 100% is defined for a fully recovered or non-depleted species that is present in all parts of its historic range (prior to any major human disturbance), each with viable populations that are ecologically functional, [2] [9] a score that may not be realistically attainable for many species even if they achieve their Recovery ...
Classification and spatial representation of ecosystems is a major challenge in itself. [30] While a standard taxonomy of organisms has existed for nearly 300 years, [ 31 ] the principles for systematization of ecosystem diversity have only been laid out recently and still require wider adoption.
Ecological indicators refer only to ecological processes; however, sustainability indicators are seen as increasingly important for managing humanity's coupled human-environmental systems. [1] The Marine Ecosystem
