  abstract = {{L}andscape fragmentation is a major threat to biodiversity. {I}t results in the transformation of continuous (hence large) habitat patches into isolated (hence smaller) patches, embedded in a matrix of another habitat type. {M}any populations are harmed by fragmentation because remnant patches do not fulfil their ecological and demographic requirements. {I}n turn, this leads to a loss of biodiversity, especially if species have poor dispersal abilities. {M}oreover, landscape fragmentation is a dynamic process in which patches can be converted from one type of habitat to another. {A} recently created habitat might suffer from a reduced biodiversity because of the absence of adapted species that need a certain amount of time to colonize the new patch (e.g. direct meta-population effect). {T}hus landscape dynamics lead to complex habitat spatiotemporal structured, in which each patch is more or less continuous in space and time. {I}n this study, we define habitat spatial structure as the degree to which a habitat is isolated from another habitat of the same kind and temporal structure as the time since the habitat is in place. {P}atches can also display reduced biodiversity because their spatial or temporal structures are correlated with habitat quality (e.g. indirect effects). {W}e discriminated direct meta-community effects from indirect (habitat quality) effects of the spatiotemporal structure of habitats on biodiversity using {C}ollembola as a model. {W}e tested the relative importance of spatial and temporal structure of habitats for collembolan diversity, taking soil properties into account. {I}n an agroforested landscape, we set up a sampling design comprised of two types of habitats (agriculture versus forest), a gradient of habitat isolation (three isolation classes) and two contrasting ages of habitats. {O}ur results showed that habitat temporal structure is a key factor shaping collembolan diversity. {A} reduced diversity was detected in recent habitats, especially in forests. {I}nteractions between temporal continuity and habitat quality were also detected by taking into account soil properties: diversity increased with soil carbon content, especially in old forests. {N}egative effects of habitat age on diversity were stronger in isolated patches. {W}e conclude that habitat temporal structure is a key factor shaping collembolan diversity, while direction and amplitude of its effect depend on land use type and spatial isolation.},
