摘要: A biodiversidade do solo enfrenta pressoes crescentes das acoes humanas, incluindo a conversao, degradacao e fragmentacao de habitats. O efeito desses fatores somado as mudancas climaticas nao reduz apenas diversidade abundância da biota solo, mas tambem suas funcoes servicos ecossistemicos. Os nematoides constituem um importante modelo para compreender respostas aos efeitos dos disturbios antropicos climaticas, uma vez que eles ocupam posicao central na cadeia alimentar apresentam taxonomica funcional. Caatinga, mosaico florestas tropicais sazonalmente secas ocorre somente no Brasil, tem enfrentado forte influencia antropicos, como agropecuaria exploracao diversos recursos naturais. Alem disso, ameacam Caatinga podem ate agravar os antropicos. As ecossistemicos fornecidos pelos em sao afetados principalmente por fisicos edaficos, temperatura precipitacao.
