Some consideraes must be made on Biodiversity or Biological Diversity, since it is a recent term and sufficiently spread out in the technician-scientific scene. This text sketches strategies for the integration of the biological inventories in order to contemplate the multiplicity of tasks assumed for signatory countries in the Convention on Biological Diversity. According to Decree n 2519, of 16 of March of 1998 apud LEWINSOHN (2001, P. 377) Biodiversity is ' ' the variety of organisms livings creature of all the origins, understanding, amongst others, terrestrial ecosystems, marine and other aquatic ecosystems and the ecological complexes of that they are part; understanding still the species diversity inside, between species and of ecossistemas' '. The species diversity inside can be understood as ' ' assignment of the genetic diversity; but it must include the diversity of ectipos, the ecological and/or genetic differentiation of populations equally that inhabit distinct regions or environments e, thus, for diante' ' (LEWINSOHN, 2001, p.377). The part most problematic of this definition is the ecosystem diversity.
As GASTON apud LEWINSOHN (2001, p.377) points, it has doubts on if this assigns diversity of habitats or if it also involves the energy flows that are important in the ecosystem notion. Thomas Lewinsohn (2001, P. 379) considers a conceptual model of biodiversity based on three dimensions: genes, species and ecosystems. These dimensions are not independent between itself; the biodiversity agreement depends of the interconnection of the information of diversity of genes, species and ecosystems. Therefore, a complete inventory will offer measured of genetic diversity of all the populations, of all the species, in all the ecosystem compartments. However, this exhausting inventory is always impracticable. Valley the penalty then, to rationalize the carried through inventories bringing two consequences: the exploitation most effective of resources of the work of field and the fast production of results for conservation, handling and exploitation of biodiversity. (LEWINSOHN, 2001, P. 380) the basic concept of this strategy was defined by LEWINSOHN (2001, P. 380): One is about in such a way secionar the total volume for plans and combinations that let us can get estimates for the total structure of biodiversity through a combination of interpolations. The factor most critical to advance in this direction is the accomplishment of inventories samples that offer simultaneous information of different axles of variation. The interchange of information is the starting point for any initiative; this says respect to the contact between geneticistas, taxonomistas, ecologists or specialists in system of geographic information, that even so limited will have to produce the opportunism, the comparabilidade of results, the convergence for common areas of work and the joint planning. (LEWINSOHN, 2001, P. 382) For the real knowledge of biodiversity an integration of these involved areas is necessary, initiating with planning of the research, becoming necessary that it advances in all the dimensions. As ' is mentioned to LEWINSOHN (2001, P. 384); ' integrated inquiry of these dimensions it allows to surpass the inherent limitations to the prompt and separate description of each aspect of biodiversidade' ' ; understanding its structure organizacional and the processes keep that it, we will be able to foresee its behavior in future scenes.
