The Bulgarian Biodiversity Portal is a part of the global information exchange network established by the Convention on Biodiversity (Clearing House Mechanism - CHM). Its purpose is to offer directly or provide links to the information on biodiversity you need.
The smallest area of land that can be delineated on a map of a particular scale; used in land evaluation as the basis of spatial variation.
land quality (LQ)
A complex attribute of land, which acts in a manner distinct from the actions of other land qualities in its influence on the suitability of land for a specified kind of use.
The right to exclusively occupy and use a specified area of land. Tenure may also be limited to certain resources(resource) ("resource tenure") such as timber but not to all resources in a given area. Tenure may be held by individuals, communities, government, or corporations.
land use requirements (LUR)
The requirements are related to growth and yield of crops and trees, animal husbandry, land management and conservation. The expression of the conditions for successful implementation are described for each LUT, e.g. growth requirements of certain tree species.
- A crop cultivar or animal breed that evolved with and has been genetically improved by traditional agriculturalists, but has not been influenced by modern breeding practices.
- Farmer-developed cultivars of crop plants which are adapted to local environmental conditions.
- Primitive or antique variety usually associated with traditional agriculture. Often highly adapted to local conditions.
The Leipzig Declaration on conservation and sustainable utilization of plant genetic resources(genetic resource) for food and agriculture, Leipzig, 23 June 1996.
Characteristic structure of a plant or animal.
life sciences companies
Companies which combine businesses in pharmaceutical, agricultural chemicals and products, and food and nutrition.
A homozygous, pure breeding group of individuals phenotypically distinct from other members of the same species; broader than strain.
A management system involving the use of off-site methods such as zoological parks, botanic gardens, arboretums, and captive breeding programs to protect and maintain biological diversity in plants, animals, and microorganisms
living modified organisms (LMOs)
- All organisms produced through the use of recombinant DNA technology, with a wider range of modifying technologies relevant when considering living modified prokaryotes(prokaryote) and yeast.
- Genetically modified organisms (GMOs) whose genetic material does not occur naturally by mating or natural recombination.
The site on a chromosome occupied by a specific gene.
low-input production environment
A production environment where one or more rate-limiting inputs impose continuous or variable severe pressure on livestock, resulting in low survival, reproductive rate or output. Output and production risks are exposed to major influences which may go beyond human management capacity.
