Glossary of terms related to the CBD

 

Bacillus thuringiensis (Bt)
a natural enemy of insects which was isolated from dead silk worms. This bacterium kills insects with the help of a protein, the so-called Bt-toxin. More than 50 Bt-toxins have been detected, each with its own characteristics. [CUB]
backcross
the cross of a hybrid with either of its parents (or a genetically equivalent individual). [CUB]
bacteria
members of a group of diverse single-celled organisms; organisms lacking a nucleus. [CUB]
bacteriophages
a group of viruses whose hosts are specifically bacteria. [CUB]
baseline data
fundamental units of basic inventory information that are crucial for biodiversity conservation planning and management. These are both biotic and abiotic and usually include: (1) the presence and/or abundance of species and other units; (2) other dependent biotic data (e.g. plant cover for macroarthropods); (3) the appropriate influential abiotic variables, and (4) human variables. [GBA]
benthic
living on or in the bottom (in contrast to pelagic).
benthos
organisms living on or in the bottom of oceans, seas, rivers, lakes and other water bodies. [JVG]
Depending on the size of the organisms, benthos is regarded as macrobenthos (organisms > 1000 m), meiobenthos (organisms between 42 m and 1000 m) and nanobenthos or microbenthos (organisms < 42 m). Depending on the depth distribution, benthos is regarded as epibenthos (living between low water line and 200 m depth), mesobenthos (living at depths between 200 and 1000 m), hypobenthos (living between 1000 and 2000 m) and abyssal benthos (living below 2000 m).

(Syn.: biodiversity)
It appears that the term 'biological diversity' was first defined as including two related concepts, genetic diversity (the amount of genetic variability within species) and ecological diversity (the number of species in a community of organisms) by Norse and McManus (1980). There are at least 25 more definitions of biological diversity. The one given on top is the definition used in the Convention text. Other definitions:
- the totality of genes, species, and ecosystems in a region or the world.
- the variety of life in all its forms, levels and combinations, encompassing genetic diversity, species diversity and ecosystem diversity. [FAO]
- a variety or multiformity, the condition of being different in character or quality (R.Patrick,1983)
- the variety and variability among living organisms and the ecological complexes in which they occur.
Diversity can be defined as the number of different items and their relative frequency. For biological diversity, these items are organized at many levels, ranging from complete ecosystems to the chemical structures that are the molecular basis of heredity. Thus, the term encompasses different ecosystems, species, genes, and their relative abundance (OTA, 1987).
- the variety of the world's organisms, including their genetic diversity and the assemblages they form. It is the blanket term for the natural biological wealth that undergirds human life and well-being. The breadth of the concept reflects the interrelatedness of genes, species and ecosystems (Reid & Miller, 1989).
- the wealth of life on earth including the millions of plants, animals, and micro-organisms as well as the genetic information they contain and the ecosystems that they create (AID, 1989).
- the variety of life and its processes (U.S. Forest Service, 1990).
- encompasses all species of plants, animals, and microorganisms and the ecosystems and ecological processes of which they are parts. It is an umbrella term for the degree of nature's variety, including both the number and frequency of ecosystems, species, or genes in a given assemblage (McNeely et al., 1990).
- the variety of life on all levels of organization, represented by the number and relative frequencies of items (genes, organisms and ecosystems (EPA, 1990).
- the variety of genes, genotypes and genepools and their relationships with the environment at molecular, population, species and ecosystem levels (FAO, 1990).
- the genetic, taxonomic and ecosystem variety in living organisms of a given area, environment, ecosystem or the whole planet (McAllister, 1991).
- the full range of variety and variability within and among living organisms and the ecological complexes in which they occur; encompasses ecosystems or community diversity, species diversity and genetic diversity (Pending legislation, U.S. Congres 1991).
- those environmental goals that go beyond human health concerns (Environmental Law Institute, Fischman, 1991).
- the variety of life and its processes. It includes the variety of living organisms, the genetic differences among them, and the communities and ecosystems in which they occur (Keystone Dialogue, 1991)
- the variety and variability of all animals, plants and micro-organisms on earth, - can be considered at three levels - genetic diversity (variability within species), species diversity, and habitat diversity (Overseas Development Administration, 1991).
- I suggest a fourth category - functional diversity - the variety of different responses to environmental change, especially the diverse space and time scales with which organisms react to each other and the environment (J. Steele, 1991).
- the totality of genes, species, and ecosystems in a region (WRI, IUCN and UNEP, 1992).
- the total variety of life on earth. It includes all genes, species and ecosystems and the ecological processes of which they are part (ICBP, 1992).
- full range of variety and variability within and among living organisms, their associations, and habitat-oriented ecological complexes. Term encompasses ecosystem, species, and landscape as well as intraspecific (genetic) levels of diversity (Fiedler & Jain, 1992).
- the variety of organisms considered at all levels, from genetic variants belonging to the same species through arrays of species to arrays of genera, families, and still higher taxonomic levels; includes the variety of ecosystems, which comprise both the communities of organisms within particular habitats and the physical conditions under which they live (Wilson, 1992).
- complex beyond understanding and valuable beyond measure, biodiversity is the total variety of life on Earth (Ryan, 1992).
- the structural and functional variety of life forms at genetic, population, species, community, and ecosystems levels (Sandlund et al., 1993).
- is the ensemble and the interactions of the genetic, the species and the ecological diversity, in a given place and at a given time (di Castri, 1995).
- is the ensemble and the hierarchical interactions of the genetic, taxonomic and ecological scales of organization, at different levels of integration (di Castri & Youns, 1996).
biological pesticide (biopesticide)
a generic term, not specifically definable, but generally applied to a biological control agent, usually a pathogen, formulated and applied in a manner similar to a chemical pesticide, and normally used for the rapid reduction of a pest population for short term pest control [FAO bis]
biological resources
includes genetic resources, organisms or parts thereof, populations, or any other biotic component of ecosystems with direct, indirect or potential use or value for humanity. (Syn.: biotic resources) [CBD]
biologics

biopesticide
- pesticide made from biological sources, that is from toxins which occur naturally.
- naturally occurring biological agents used to kill pests by causing specific biological effects rather than by inducing chemical poisoning. The idea is based on mimicking processes that arise naturally (e.g. protecting the coffee bean by its caffeine content), and is argued to be favorable to conventional chemical pesticides as it is more easily biodegradable and more target specific. A pesticide in which the active ingredient is a virus, fungus, or bacteria, or a natural product derived from a plant source. A biopesticide's mechanism of action is based on specific biological effects and not on chemical poisons. [CUB]

bioregion
a territory defined by a combination of biological, social, and geographic criteria, rather than geopolitical considerations; generally, a system of related, interconnected ecosystems. [GBA]
bioremedation

[FAO]
breed at risk
any breed that may become extinct if the factors causing its decline in numbers are not eliminated or mitigated.
Breeds may be in danger of becoming extinct for a variety of reasons. Risk of extinction may result from, inter alia, low population size; direct and indirect impacts of policy at the farm, country or international levels; lack of proper breed organization; or lack of adaptation to market demands. Breeds are categorized as to their risk status on the basis of, inter alia, the actual numbers of male and / or female breeding individuals and the percentage of pure-bred females. FAO has established categories of risk status: critical, endangered, critical-maintained, endangered-maintained, and not at risk. [FAO]
