Conteúdo: | The MACROFAUNA database is the result, in a first time, of a pioneer version written and developed in Dbase IV TM by Carlos Fragoso at the beginning of the 1990's and, in a second time, of a consultation between all participants of the two International Biodiversity Observation Year (IBOY) workshops held in Bondy (France) in June 2000 and december 2001. The major interest of the MACROFAUNA database is that it will constitute a considerable sum of data which can be used as basic tool as for numerous of fundamental questions than for applied researches. Main objectives are : 1- to assess the soil macrofauna biodiversity at different geographic scales, from local to regional. 2 - to assess the influence of land use, biota pertubation or specific environmental factors on soil macrofauna. 3 - to assess the influence of soil macrofauna communities modifications on soil properties and 4 - to research bioindicators associated with specific environmental parameters or soil pertubations. All data are collected on the basis of the sampling pattern as defined by the Tropical Soil Biology and Fertility (TSBF) protocole : a site is represented by a transect or a quadrat and identical soil monolithes are carried out at regular intervals. Each monolithe is divided in regular strata. MACROFAUNA database contains at present data for 843 sites and 7486 samples, distributed over 37 countries through the worl (Europe : 42 sites and 557 samples ; North America : 12 sites and 144 samples ; Central and South America : 460 sites and 4006 samples ; Africa : 216 sites and 1960 samples ; and Asia/Oceania : 113 sites and 819 samples). MACROFAUNA V2.0 was written in Microsoft Access and contains 155 variables distributed among 5 distinct groups: 3 are linked to the different levels of precision of field sampling (sites, soil samples and strata) with 123 environmental and biological variables and the two others, to the taxonomical aspect of the sampled fauna and to the bibliographical references in which results were published. Because of the great number of variables and to make data input and extraction easier, the database was divided in two distinct interfaces: the "data input interface", an interface in wich data are distributed in 5 "one-to-several" related tables corresponding to the 5 variables groups, and the "data extraction interface", in which all data are brought together in the same table. Search and extraction of data can be executed via keywords and an advanced search can be executed by way  of a combinaison of keywords with the help of classical Boolean operators. The result of a query appears in tabular form and can be directly exported under numerous formats (txt, rtf, ASCII, Microsoft Excel...). A preliminary result of the data analysis underlines a soil fauna total density significantly higher in the tropical areas compared to temperatures ones because of a great abundance of termites and ants, and a soil fauna total biomass significantly higher in the temperate areas because of a greater abundance of earthworms.
