Food-web dynamics: Animal nitrogen swap for plant carbon

  author={John Klironomos and Miranda M. Hart},
Predatory plants are typically found in discrete groups living under conditions of extreme nutrient stress. But we show here how a common species of boreal tree can act indirectly as a predator of arthropods living in the soil by virtue of a fungal symbiont that supplies it with animal nitrogen in exchange for the plant's carbon. If the way in which this partnership operates proves to be widespread, ideas about nutrient cycling and food-web dynamics in temperate forests may have to be modified. 
Nitrogen Economy and Nitrogen Environmental Interactions in Conifers
The metabolic relevance of two key amino acids, arginine and phenylalanine, as well as other processes potentially involved in the nitrogen economy of conifers are discussed in the current review.

Decomposition is an ecological process that recycles dead tissues, mainly from primary production, into nutrients in the soil. The Ecology of Soil Decomposition describes trophic interactions between
Predatory fungi, wood decay, and the carbon cycle
The primary function of predatory fungi appears to be that of wood decay and hence they are cellulolytic or ligno-cellulolytic fungi that attack other organisms as sources of nitrogen to supplement a primarily carbohydrate (woody) diet.
Tri-Party Underground Symbiosis between a Weevil, Bacteria and a Desert Plant
A unique tri-party interaction between a plant, a beetle, and a bacterium is described, which shows the important ecological role of desert plant roots and provides an example of a sustainable consortium of living organisms coping with the challenging desert environment.
Populus Rhizosphere and the Ectomycorrhizal Interactome
New insights learned from genomic-level studies involving Populus and its soil microbial community, especially symbiotic ectomycorrhizal interactions, are discussed, focusing on the communication and signaling in the soil between the tree roots and the mycorrhIZal fungi.
Nutrient transfer to plants by phylogenetically diverse fungi suggests convergent evolutionary strategies in rhizospheric symbionts
Potential convergent evolutionary strategies for nutrient transfer between insect pathogenic endophytes and mycorrhizal fungus are explored.
Rhizosphere fauna: the functional and structural diversity of intimate interactions of soil fauna with plant roots
In this review, areas of recent exciting progress are highlighted and the black boxes that still need to be illuminated by rhizosphere zoologists and ecologists are pointed out.
The role of wood decay fungi in the carbon and nitrogen dynamics of the forest floor
decomposed amino acid that tracks the mycelial free amino acid pool. Its movement can be imaged by counting photon emissions from a scintillant screen in contact with the mycelial system. This method


Net transfer of carbon between ectomycorrhizal tree species in the field
Different plant species can be compatible with the same species of mycorrhizal fungi, and be connected to one another by a common mycelium,. Transfer of carbon, nitrogen, and phosphorus, through
Mycorrhizal functioning: an integrative plant-fungal process.
This work focuses on the application of VA mycorrhizae to ecosystem restoration and reclamation in the context of VAM commercialization and the role of fungal symbionts in this process.
Biogeochemistry: An Analysis of Global Change
Biogeochemistry-winner of a 2014 Textbook Excellence Award (Texty) from the Text and Academic Authors Association-considers how the basic chemical conditions of the Earth, from atmosphere to soil to
Arthropod regulation of micro- and mesobiota in below-ground detrital food webs
Functional groups, the basic units of an ecosystem model, have usually been defined by broad taxonomic relationships even though criteria that describe roles in a system would be more suitable.
Destruction of nematodes by species of Pleurotus
On water agar, Pleurotus ostreatus produces tiny droplets of toxin from minute spathulate secretory cells, and directional hyphae converge on the body orifices of the nematode,stimulated by leakage products from the immobilized host.
