Accumulations of living and dead epiphytes in the canopy of rainforest trees provide an aboveground nutrient resource. A wide range of host tree species in both temperate and tropical rainforests gain access to these nutrients by putting forth extensive networks of adventitious roots beneath the epiphyte mats they support. 
Mycorrhizal, Endophytic and Ecomorphological Status of Tree Roots in the Canopy of a Montane Rain Forest
TLDR
Canopy roots completely lacked mycorrhizal colonization, but showed a high abundance of endophytic fungi suggesting a reduced ability for nutrient acquisition compared with terrestrial roots.

Factors affecting the initiation and growth of aboveground adventitious roots in a tropical cloud forest tree: an experimental approach
TLDR
Wet epiphytes and the nutrients they intercept and retain within the canopy may cue adjacent host tissue to exploit this resource to produce adventitious roots.
The effects of silvicultural disturbances on cryptogam diversity in the boreal-mixedwood forest
In northern forests, cryptogams (spore producing plants) occupy a key position in forest ecosystem diversity and function. Forest harvesting and silvicultural practices have the potential to reduce...
Diversity of Species and Interactions in the Upper Tree Canopy of Forest Ecosystems
TLDR
The upper tree canopy of many forest ecosystems fosters extremely diverse communities, particularly of vascular epiphytes and arthropods, which contribute to the total amounts of resources, provide opportunities for resource specialization, and temporally spread available resources in the canopy throughout the year.
Elements of disturbance that affect epiphyte vitality in a temperate rainforest: an experimental approach
Epiphytes are an abundant and diverse component of many wet temperate forests and have significant roles in ecosystem processes. Little is known about the processes and rates of their death and

Aboveground adventitious roots and stemflow chemistry of Ceratopetalum virchowii in an Australian montane tropical rain forest
TLDR
It is hypothesize that the growth of the aboveground adventitious roots of C. virchowii is influenced by the high nutrient content of its stemflow and branchflow drainage, and by the moist condition of its woody surfaces which remain wetted for relatively long periods after rainfalls.
Nitrogen-15 natural abundance in a montane cloud forest canopy as an indicator of nitrogen cycling and epiphyte nutrition
TLDR
These findings support earlier results showing that canopy soil is derived mainly from epiphytes, with only minor inputs from host tree matter, and appear to be largely detached from the tree-soil cycle.

Nutrient Retention by the Root Mat of an Amazonian Rain Forest
TLDR
First evidence supporting the ability of the root map on the surface of poor, depleted tropical soils to efficiently take up dissolved nutrients before they percolate down to mineral soil is shown.
Nutrient scavenging of rainfall by the canopy of an Amazonian rain forest.
TLDR
It is reported that nutrients are filtered out of the rainwater as the water passes through the forest canopy, and it is hypothesized that this interception is an important nutrient-conserving mechanism for the Amazonian forests.
A method of access into the crowns of emergent and canopy trees
TLDR
A method of climbing into the canopy of tall trees is described, using equipment which does not damage the tree and which can be carried by a single person, and which provides access to the peripheral branches where flowers and fruits are often found.
