title: Data from: Host-specific effects of soil microbial filtrates prevail over those of arbuscular mycorrhizae in a fragmented landscape

description: Plant-soil interactions have been shown to determine plant community
 composition in a wide range of environments. However, how plants
 distinctly interact with beneficial and detrimental organisms across
 mosaic landscapes containing fragmented habitats is still poorly
 understood. We experimentally tested feedback responses between plants and
 soil microbial communities from adjacent habitats across a disturbance
 gradient within a human-modified tropical montane landscape. In a
 greenhouse experiment, two components of soil microbial communities were
 amplified; arbuscular mycorrhizal fungi (AMF) and a filtrate excluding AMF
 spores from the soils of pastures (high disturbance), coffee plantations
 (intermediate disturbance), and forest fragments (low disturbance), using
 potted seedlings of 11 plant species common in these habitats (pasture
 grass, coffee, and 9 native species). We then examined their effects on
 growth of these same 11 host species with reciprocal habitat inoculation.
 Most plant species received a similar benefit from AMF, but differed in
 their response to the filtrates from the three habitats. Soil filtrate
 from pastures had a net negative effect on plant growth, while filtrates
 from coffee plantations and forests had a net positive effect on plant
 growth. Pasture grass, coffee and five pioneer tree species performed
 better with the filtrate from “away” (where these species rarely occur)
 compared to “home” (where these species typically occur) habitat soils,
 while four shade tolerant tree species grew similarly with filtrates from
 different habitats. These results suggest that pastures accumulate
 species-specific soil enemies, while coffee plantations and forests
 accumulate beneficial soil microbes that benefit pioneer native plants and
 coffee, respectively. Thus, compared to AMF, soil filtrates exerted
 stronger habitat and host-specific effects on plants, being more important
 mediators of plant-soil feedbacks across contrasting habitats.

 rate (RGR) with live (arbuscular mycorrhizal fungi and soil microbial
 filtrates) from pastures, coffee plantations and forest
 fragmentsThe data was collected
 from a greenhouse experiment in which 11 plant species (read below) were
 growth with either sterilized soil, or sterilized soil inoculated with
 arbuscular mycorrhizal fungi (AMF) or a soil microbial filtrate obtained
 from three habitats: pastures, coffee plantations, or forest fragments.
