Plant traits and mycorrhizae mediate Janzen-Connell effect in tree saplings

In this video podcast, Alissa Brown highlights the role of shade tolerance and mycorrhizal type on conspecific negative density dependence in seedlings and saplings in forest. Alissa’s findings have recently been published in Journal of Ecology. Have a look at the video to discover what she found! If you want to know more, check out the full paper entitled ”Shade tolerance and mycorrhizal type may influence sapling susceptibility to conspecific negative density dependence“.

Alissa’s video can also be found on the Journal of Ecology YouTube channel (English subtitles available).


Alissa Brown is a forest ecologist who recently finished her Ph.D. in Biology at the University of North Carolina at Chapel Hill. Her Ph.D. work focused on tree recruitment patterns in temperate forests, looking for evidence of conspecific negative density dependence. Alissa begins her post-doctoral work at the Morton Arboretum in the summer of 2019, where she will investigate changes in North American tree distributions after the last glacial maximum.
