A review of studies that tested for Janzen–Connell effects

(either distance dependence, density dependence or both) on a

per species basis for

different life-forms, plant families, habitats, locations, and

countries around the world. We also included seed size or weight

and information on the local

abundance of the focal species if these data were reported.Habitat
