Managing soil fertility in organic farming systems [PDF]

, 2002
Complex relationships exist between different components of the organic farm and the quantity and quality of the end products depend on the functioning of the whole system.

Soil phosphorus drives subcontinental patterns of carbon isotope discrimination across Australia

New Phytologist, EarlyView.
Summary Several transects have been established to study the sensitivity of carbon isotope discrimination (Δ13C) in woody plants to mean annual precipitation (MAP) across Australia. These have shown a surprising divergence in Δ13C‐MAP sensitivity among subcontinental regions.

Quantifying carbon allocation to mycorrhizal fungi by temperate forest tree species across a nitrogen availability gradient [PDF]

, 2013
Terrestrial ecosystems make up the largest carbon pool with a major portion of that being forests. With carbon being a major concern due to global climate change, being able to make accurate models is increasingly important. Studies have shown that trees

Acquisitive root exploration strategies help maintain higher peak sap flux rates during summer drought, but more root biomass does not

New Phytologist, EarlyView.
Summary Roots are responsible for soil water uptake, yet little is known about how variation in fine‐root traits relates to whole‐tree water movement, particularly during periods of drought. By combining a 3‐yr dataset monitoring sap flow rates with measures of fine‐root biomass, length, and morphology across 10 tree species, we addressed hypotheses ...

Reproducible hairy root transformation and spot-inoculation methods to study root symbioses of pea

Plant Methods, 2011
Pea has lagged behind other model legumes in the molecular study of nodulation and mycorrhizae-formation because of the difficulty to transform its roots and its poor growth on agar plates.

“Fairy rings” of participation: the invisible network influencing participation in online communities [PDF]

, 2010
Individuals participate in many different ways in online communities. There is an extensive body of research describing participation as a key metaphor in communities of practice and stressing that participatory mobility is influenced by underground ...

The phylogenetic structure of plant communities drives the belowground transmission of fungal pathogens

New Phytologist, EarlyView.
Summary Biodiversity is known to influence disease risk, yet the pathways of pathogen transmission within plant communities remain poorly understood, especially belowground. In particular, how soil‐borne pathogens move from resident vegetation and soil to colonize new hosts is unresolved.

Ecological and genomic variation in ectomycorrhizal fungal exploration types

New Phytologist, EarlyView.
Summary Ectomycorrhizal fungi (EMF) produce mycelia with variable extension and complexity, which can be classified according to soil ‘exploration types’ (ETs). ETs have received attention as one of the few mycorrhizal trait frameworks, but without an empirical classification of ET functional diversity and environmental preferences, understanding and ...

THE ECOLOGY OF MUTUALISM [PDF]

, 1982
Elementary ecology texts tell us that organisms interact in three fundamen­ tal ways, generally given the names competition, predation, and mutualism. The third member has gotten short shrift (264), and even its name is not generally agreed on.

Endophytic and ectomycorrhizal, an overlooked dual ecological niche? Insights from natural environments and Russula species

New Phytologist, EarlyView.
Summary Ectomycorrhizal fungi (EcMF) are key components of temperate ecosystems, and recent studies suggest that they can also inhabit non‐EcM plant roots as endophytes. We aimed to (1) provide new evidence of EcMF colonization of non‐EcM hosts, (2) offer direct microscopic confirmation of such endophytism and (3) assess factors influencing ...
