Definition von biodiversity im Englisch Englisch wörterbuch
the diversity (number and variety of species) of plant and animal life within a region
the diversity of plant and animal life in a particular habitat (or in the world as a whole); "a high level of biodiversity is desirable
The relative abundance and variety of plant and animal species and ecosystems within particular habitats
Biodiversity, or biological diversity, is the term for the variety of life and the natural processes of which living things are a part This includes the living organisms and the genetic differences between them and the communities in which they occur The concept of biodiversity represents the ways that life is organized and interacts on our planet These interactions can take place on scales ranging from the smallest, at the chromosome level, to organisms, ecosystems, and even to entire landscapes
In an environments created solely by nature, there is a variety of plant and animal life, ranging from the very small to the very large Nature has created a natural system for post and disease control However, when we only incorporate limited variety in our landscapes, the system of checks and balances breaks down In general, the more diverse we can make our gardens, the healthier they will be
A property of ecosystems related to the number of different plant and animal species they contain
The diversity of different species (species diversity), genetic variability among individuals within each species (genetic diversity), and variety of ecosystems (ecosystem diversity) Abbreviation of biological diversity
The word "biodiversity" is a contraction of "biological diversity" and is commonly used to describe the number, variety and variability of living organisms Biodiversity is commonly defined in terms of the variability of genes, species and ecosystems, corresponding to these three fundamental and hierarchically related levels of biological organization
(1) the variety of life forms, the ecological roles they perform, and the genetic diversity they contain (Wilcox 1984: 640); (2) the variety from molecular, population, and interspecific levels up to the heterogeneity of ecosystems and landscapes (Hansen and diCastri 1992: 5) (syn biological diversity)
The variety of all life forms - the different plants, animals and micro-organisms, the genes they contain, and the ecosystems of which they form a part
The variety of life forms: the different plants, animals and microorganisms, the genes they contain, and the ecosystems they form It is usually considered at three levels: genetic diversity, species diversity and ecosystem diversity
The variety of species and ecosystems, the variability of genes within the species and the ecological complexes of which they are a part
The sum of life and its processes including the variety of living plants, animals and other organisms, the genetic differences among them, the communities and ecosystems in which they occur, and the ecological and evolutionary process that keep them functioning
the total diversity and variability of living things and of the systems of which they are a part This includes the total range of variation in and variability among systems and organisms at the bioregional, ecosystem and habitat levels, at the various organismal levels down to species, populations and individuals and at the level of the population and genes
the diversity of plants, animals, and other living organisms in all their forms and levels of organization, including genes, species, ecosystems, and the evolutionary and functional processes that link them
the diversity of plant and animal life in a particular habitat (or in the world as a whole); "a high level of biodiversity is desirable"
Biodiversity is the existence of a wide variety of plant and animal species living in their natural environment. the variety of plants and animals in a particular place. Quantity of plant and animal species found in a given environment. Sometimes habitat diversity (the variety of places where organisms live) and genetic diversity (the variety of traits expressed within a species) are also considered types of biodiversity. The estimated 3-30 million species on Earth are divided unequally among the world's habitats, with 50-90% of the world's species living in tropical regions. The more diverse a habitat, the better chance it has of surviving a change or threat to it, because it is more likely to be able to make a balancing adjustment. Habitats with little biodiversity (e.g., Arctic tundra) are more vulnerable to change. The 1992 Earth Summit resulted in a treaty for the preservation of biodiversity
a large number and wide range of species of animals, plants, fungi, and microorganisms Ecologically, wide biodiversity is conducive to the development of all species
The variety and abundance of species, their genetic composition, and the natural communities, ecosystems, and landscapes in which they occur
The variety and variability among living organisms and the ecosystems in which they occur Biodiversity includes the number of different items and their relative frequencies; these items are organized at many levels, ranging from complete ecosystems to the biochemical structures that are the molecular basis of heredity Thus, biodiversity encompasses expressions of the relative abundances of different ecosystems, species, and genes
the diversity of life in all its forms and organisation that comprise the natural world Diversity includes genetic diversity, species diversity and ecosystem diversity (see overview below) For an audio and visual example of life's diversity go to [3: Biodiversity glossary of terms ]; [3: glossary ]; [3: What is biodiversity? ]; [3: BIODIVERSITY SERVERS ]; [3: Online Biodiversity Web Encyclopedia of Biodiversity ]; [3: Ecology, Biodiversity & the Environment ]; [3: People and Biodiversity ]; [3: The Roles of Biodiversity in Creating and Maintaining the Ecosphere ]
The variety of life in all its forms, levels and combinations Includes ecosystem diversity, species diversity, and genetic diversity
A shortening of the term "biological diversity " The diversity of life on Earth The variability among living organisms and their interactions, both within species and between species, between ecosystems and across landscapes
The variety of life on Earth and the natural patterns it forms, including all species of life and the genes that each individual contains, as well as the critical inter-relationships or "ecosystems" which those species form
The variability among living organisms from all sources, including land based and aquatic ecosystems, and the ecosystems of which they are part These include diversity within species, between species, and of ecosystems Diversity is the key to ensuring the continuance of life on Earth It is also a fundamental requirement for adaptation and survival and continued evolution of species
The variability among living organisms; this includes diversity within species (genetic diversity), between species and of ecosystems
The variety of different species in an ecosystem, genetic variation within a population of a species, and variety of kinds of ecosystems Greater biodiversity makes species and systems more resilient, while loss of biodiversity weakens them, making them more vulnerable to extinction
