Plant–soil feedback links negative distance dependence and light gradient partitioning during seedling establishment
Tree species coexistence has often been explained through either negative distance-dependent/density-dependent (NDD) mortality or resource-based niche partitioning. However, these two influential mechanisms for structuring community dynamics have rarely been investigated simultaneously. Negative conspecific effects, like those caused by plant–soil feedbacks (PSF), could link these two mechanism...
متن کاملLight signaling controls nuclear architecture reorganization during seedling establishment.
The spatial organization of chromatin can be subject to extensive remodeling in plant somatic cells in response to developmental and environmental signals. However, the mechanisms controlling these dynamic changes and their functional impact on nuclear activity are poorly understood. Here, we determined that light perception triggers a switch between two different nuclear architectural schemes ...
متن کاملEctomycorrhizal networks and seedling establishment during early primary succession.
Ectomycorrhizal (ECM) fungal mycelia are the main organs for nutrient uptake in many woody plants, and often connect seedlings to mature trees. While it is known that resources are shared among connected plants via common mycorrhizal networks (CMNs), the net effects of CMNs on seedling performance in the field are almost unknown. CMNs of individual ECM fungal species were produced in an early s...

متن کاملSeed mass, seedling size and neotropical tree seedling establishment
1 We examined amongand within-species effects of seed mass for seedling establishment from seed to 5 years of age in a field experiment at Paracou, French Guiana. 2 Six seeds of each of eight species were weighed and planted into each of 120 plots (1 m 2 ) throughout closed-canopy forest along 12 100-m transects in 1998. 3 We described the microhabitat of each planting site using principal comp...
