Biogeography is the study of the biosphere and of human effects on plants and animals.
Putting a Name on Ecosystems Overview Just as a human family has a diverse set of members living under one roof, but can be identified by one name, so too ecosystems have a diverse set of species interacting with each other and their habitat, to which a name can be given.
In the terrestrial realm, approach draws from well-established traditions in vegetation classifications because plants provide the dominant and most visible living aspects of ecosystemswhile incorporating landscape and ecological relationships found among species.
In the coastal and marine realm, our approach identifies a more flexible approach to using biota, substrate, geomorphic formation, and water column features to describe ecological units.
Over the last 25 years, NatureServe has cultivated a cadre of more than a dozen ecologists that are experts in the development of terrestrial and coastal and marine ecological classification standards, methods, and tools.
With partners, we have produced two U. Federal ecological classification standards including the U. Value By describing, classifying and tracking terrestrial ecosystems, we are able to address a complex suite of processes and functions beyond that of individual species interactions, such as old-growth forests, productive soils, and coral reefs.
Finally, many ecosystems provide the ecosystem services that we depend on, such as flood control, water quality, storm surge protection, and erosion. Our approach is being used to guide national and international classification products.
Our international products include the International Vegetation Classification and Ecological Systems. National projects include the U. NatureServe supports this approach by developing several inter-related ecosystem classifications.
These consistent and flexible classifications, including the International Terrestrial Ecological Systems Classification and the International Vegetation Classification IVCcan be applied to terrestrial regions throughout the world. The classifications are based on vegetation and ecological criteria, including vegetation growth forms and structure, plant species including the characteristic species combination of diagnostic, constant and dominant speciesand ecological characteristics such as site, disturbance, bioclimate, and biogeography.
The coastal and marine classification is based on plant and animal composition together with substrate, geomorphic formation, and water column features. These ecological classifications addresses many core needs for conservation and resource management: Describe existing ecosystem patterns, including both natural systems forests, prairies, alpine, seamounts and cultural systems plantations, orchards, lawns, jetties.
Facilitate inventory of ecosystem patterns within and across landscapes, seascapes and ecoregions. Support documentation of status and trends of vegetation and ecosystems e. Facilitate interpretation of long-term even paleo-ecological change with short-term change.
Provide a structure to track real-time ecosystem responses to invasive species, land use and climate change, by tracking semi-natural types that form by human disturbances and invasive exotic species.Oct 01, · Indian Geography| NCERT Class 9-For UPSC/IAS/CSE| Physical Features in India| Types of Vegetation - Duration: Edupedia World 20, views.
The classifications are based on vegetation and ecological criteria, including vegetation growth forms and structure, plant species (including the characteristic species combination of diagnostic, constant and dominant species), and ecological characteristics such as site, disturbance, bioclimate, and biogeography.
Biogeographic region, area of animal and plant distribution having similar or shared characteristics throughout. It is a matter of general experience that the plants and animals of the land and inland waters differ to a greater or lesser degree from one part of the world to another.
INDIA being a vast country. topography and geology and hence the country is very rich in terms of biodiversity. organism and ecosystems in geographic space and through geological time.. shows a great diversity in climate. Transcript of Biogeographical Classification of India It is one of the richest Flora regions in the country It has several species of orchids, bamboo, ferns and other plants.
Sri Lanka, which lies to the south of India, is also a country rich in species diversity. It has been connected with India through several past glaciation events by a land bridge almost kn wide.
How the biodiversity of Western Ghats originated is a still a puzzle. The region shows biogeographical affinities to the Malayan region.
