Difference between mantel test and adonis

v_coudrain at voila.fr 
Dear sig-eco users,

I would like to investigate the changes in a species community along an ecological gradient. I first thought about performing a Mantel test and infer if differences in 
species composition are related to differences in the ecological gradient. I noticed that the function adonis (package vegan) could handle continuous variables as 
well. However, the ecological gradient is not entered as a distance matrix and therefore I don't understand exactly how to interpret the outcome of the adonis test 
and what is the difference to the Mantel test. Any help will be apprectiate.

Best wishes. Valerie
