- impact assessment
- an evaluation of the likely impact on biological diversity of proposed
programmes, policies, or projects. [CUB]
- a cross between parents of similar genetic constitution which could be
from the same blood line (shared ancestry). [CUB]
- in-bred line
- in plants, a line produced by repeated selfing and selection. Results in
truebreeding and a fixed genotype. [CUB]
- - mating among related individuals.
- mating of close relatives, which reduces genetic diversity, often leading to expression of deleterious recessive characteristics and reduction
of fitness in the offspring.
- inbreeding depression
- a reduction in fitness and vigour of individuals as a result of
increased homozygosity through inbreeding in a normally outbreeding
- flow of money, goods or services deriving from the productive use of
- indicator species
- a species whose status provides information on the overall condition of
the ecosystem and of other species in that ecosystem. They reflect the
quality and changes in environmental conditions as well as aspects of
community composition. [GBA]
- indigenous peoples
- people whose ancestors inhabited a place or country when persons from
another culture or ethnic background arrived on the scene and dominated
them through conquest, settlement, or other means and who today live more
in conformity with their own social, economic, and cultural customs and
traditions than with those of the country of which they now form a part.
(Also: "native peoples" or "tribal peoples".) [GBA]
- informal contact group
- on the instructions of the President or Chair, delegates may meet in private to discuss specific matters in order to consolidate different views, reach a compromise, and produce an agreed proposal, often in the form of written text.
- in the original location. (Opposite: ex-situ)
- in-situ conditions
- conditions where genetic resources exist within ecosystems and natural
habitats, and, in the case of domesticated or cultivated species, in the
surroundings where they have developed their distinctive properties. [CBD]
- - the conservation of ecosystems and natural habitats and the
maintenance and recovery of viable populations of species in their natural
surroundings and, in the case of domesticated or cultivated species, in
the surroundings where they have developed their distinctive properties.
- - the conservation of biodiversity within the evolutionary dynamic
ecosystems of the original habitat or natural environment. [GBA]
- in situ conservation of farm animal genetic diversity
- all measures to maintain live animal breeding populations, including
those involved in active breeding programmes in the agro-ecosystem where
they either developed or are now normally found, together with husbandry
activities that are undertaken to ensure the continued contribution of
these resources to sustainable food and agricultural production, now and
in the future. [FAO]
- in-situ gene banks
- protected areas designated specifically to protect genetic variability
of particular species. [GBA]
- insurance value
- the value of biodiversity in maintaining ecosystem functions over a
range of environmental conditions. [GBA]
- integrated area management (IAM)
- management approach whereby a specific area is zoned and regulated for a
variety of uses, including research, species protection, tourism,
harvesting, cutting down trees, hunting, or fishing, that is compatible
with the management goals for the area.
- integrated pest management
- - an ecologically based strategy that relies on natural mortality
factors, such as natural enemies, weather, and crop management, and seeks
to control tactics that disrupt these factors as little as possible while
enhancing their effectiveness. [GBA]
- the challenging or control of pests through a tailored programme of
different strategies including biological control agents and
- intellectual property right
- a right enabling an inventor to exclude imitators from the market for a
- intergenerational equity
- a core proposition is that future generations have a right to an
inheritance (capital bequest) sufficient to allow them to generate a level
of well-being no less than that of the current generation. Fairness in the
treatment of different members of the same generation. [GBA]
- intertidal zone
- the zone of overlap between land and sea that is submerged at high tide
and exposed at low tide.
- introduced species
- see: alien species.
- the entry of a pest [or species] resulting in its establishment. [FAO
- introduction of a biological control agent
- the release of a biological control agent into an ecosystem or an area
where it did not exist previously. [FAO bis]
- inundative release
- the release of overwhelming numbers of a mass-produced biological
control agent in the expectation of achieving a rapid reduction of a pest
population without necessarily achieving continuing impact. [FAO bis]
- incorporation of genes of one species into a gene pool of another
- invasive species
- an introduced species which invades natural habitats.
- the surveying, sorting, cataloguing, quantifying and mapping of entities
such as genes, individuals, populations, species, habitats, ecosystems and
landscapes or their components, and the synthesis of the resulting
information for the analysis of process. [GBA]
- any animal without backbone or spinal column.
- in vitro
- - storage of living materials as tissue culture, and may include
cryopreservation (storage at low temperature, usually in liquid nitrogen).
- literally 'in glass'. Experimental reproduction of biological processes
in isolation from a living organism, e.g. tissue culture. [CUB]
- in vitro culture
- see: tissue culture.
- in vivo
- taking place in a living organism.
