Soil physico-chemical properties are critical for predicting carbon storage and nutrient availability across Australia

Autor: Jinquan Li, Ming Nie, Jeff R Powell, Andrew Bissett, Elise Pendall

Publikováno v: Environmental Research Letters, Vol 15, Iss 9, p 094088 (2020)

Soil carbon and nutrient availability play crucial roles in ecosystem sustainability, and they are controlled by the interaction of climatic, biotic, and soil physico-chemical variables. Although soil physico-chemical properties have been recognized

Environmental and Geographical Factors Structure Soil Microbial Diversity in New Caledonian Ultramafic Substrates: A Metagenomic Approach.

Autor: Véronique Gourmelon, Laurent Maggia, Jeff R Powell, Sarah Gigante, Sara Hortal, Claire Gueunier, Kelly Letellier, Fabian Carriconde

Publikováno v: PLoS ONE, Vol 11, Iss 12, p e0167405 (2016)

Soil microorganisms play key roles in ecosystem functioning and are known to be influenced by biotic and abiotic factors, such as plant cover or edaphic parameters. New Caledonia, a biodiversity hotspot located in the southwest Pacific, is one-third

Compositional divergence and convergence in local communities and spatially structured landscapes.

Autor: Tancredi Caruso, Jeff R Powell, Matthias C Rillig

Publikováno v: PLoS ONE, Vol 7, Iss 4, p e35942 (2012)

Community structure depends on both deterministic and stochastic processes. However, patterns of community dissimilarity (e.g. difference in species composition) are difficult to interpret in terms of the relative roles of these processes. Local comm

Indigenous arbuscular mycorrhizal fungal assemblages protect grassland host plants from pathogens.

Autor: Jeannine Wehner, Pedro M Antunes, Jeff R Powell, Tancredi Caruso, Matthias C Rillig

Publikováno v: PLoS ONE, Vol 6, Iss 11, p e27381 (2011)

Plant roots can establish associations with neutral, beneficial and pathogenic groups of soil organisms. Although it has been recognized from the study of individual isolates that these associations are individually important for plant growth, little

Invasive plant suppresses the growth of native tree seedlings by disrupting belowground mutualisms.

Autor: Kristina A Stinson, Stuart A Campbell, Jeff R Powell, Benjamin E Wolfe, Ragan M Callaway, Giles C Thelen, Steven G Hallett, Daniel Prati, John N Klironomos

Publikováno v: PLoS Biology, Vol 4, Iss 5, p e140 (2006)

The impact of exotic species on native organisms is widely acknowledged, but poorly understood. Very few studies have empirically investigated how invading plants may alter delicate ecological interactions among resident species in the invaded range.
