Soil invertebrates in the Tropics: a bibliographical revision.

The invertebrates are the most diverse group in the world; they colonize almost all the ecosystems and certainly give many goods and services to the human beings. The invertebrates that live in the soil contribute consistently with changes in the ecosystemic functions, affecting directly: nutrients, cycle, change in biomass contain ecological nets and inter specific relations for more voluminous organisms. For this exercise were taken the information of the six more representative magazines (2010-2016). The invertebrates in the tropics are maybe the most diverse group, although in the checking stage carried out only 64% represented tropical zones or subtropical exclusively, the rest is a comparison with temperate zones or global studious. Because of its diversity, many invertebrates are waiting for their taxonomical descriptions; many specialists are not from tropical countries. Brazil is the country with more investigations about this theme with its own investigators. No all the invertebrates have received the same attention, and the most studied groups are the orders Hymenoptera (20%), Coleopteran (12%) and Araneae (6%), many families without identification (25%), distinguishing studious in Fomicidae (24%) and Scarabaeinae (8%) mainly. The tendency is to work with those that are better described. The articles selected constitute a key for identifying the most useable methodologies, where the fall trap (30%), quadrant (11%) and transecto (9%), are remarkable over 24 methodologies, the most widespread time of studious was for only one season (< 1 year) the central point of the search in the soil (40%) and the fallen leaves (38%).
