Journal ArticleDOI
Pasture damage by an Amazonian earthworm
Armand Chauvel,Michel Grimaldi,Eleusa Barros,Eric Blanchart,Thierry Desjardins,Max Sarrazin,Patrick Lavelle +6 more
TL;DR: In this paper, soil bulk density has been shown to increase rapidly after conversion to pasture, leading to poor drainage and a reduced rate of gaseous diffusion, which limit methane consumption and promote the anaerobic production of methane.
Journal ArticleDOI
Why is the influence of soil macrofauna on soil structure only considered by soil ecologists
Nicolas Bottinelli,Pascal Jouquet,Yvan Capowiez,Pascal Podwojewski,Michel Grimaldi,Xinhua Peng +5 more
TL;DR: In this article, the main mechanisms by which soil engineers impact soil structure and proposed to classify soil engineers with respect to their capacity to produce biostructures and modify them, underlined the lack of studies considering biostructure dynamics and presented recent techniques in this purpose.
Journal ArticleDOI
The influence of soil cover organization on the floristic and structural heterogeneity of a Guianan rain forest
Daniel Sabatier,Michel Grimaldi,Marie Francoise Prevost,Julie Guillaume,Michel Godron,Mireille Dosso,Pierre Curmi +6 more
TL;DR: In this article, the impact of soil cover organization on the forest community has been studied in a 19-ha tract at Piste de St Elie station in French Guiana, where 195 species each represented by at least 10 individuals were chosen from records of the position, diameter at breast height (dbh) and precise identification by botanical sampling of 12104 ligneous plants.
Journal ArticleDOI
Ecosystem engineers in a self-organized soil: A review of concepts and future research questions
Patrick Lavelle,A. V. Spain,Manuel Blouin,George G. Brown,Thibaud Decaëns,Michel Grimaldi,José Juan Jimenez,Ddoyle Mckey,Jérôme Mathieu,Elena Velasquez,Anne Zangerlé +10 more
TL;DR: In this article, the authors propose a conceptual framework for sustainable use of the soil resource and present seven general research questions whose resolution will provide a firmer base for the proposed conceptual framework.
Journal ArticleDOI
This ped is my ped: Visual separation and near infrared spectra allow determination of the origins of soil macroaggregates
Elena Velasquez,Céline Pelosi,Didier Brunet,Michel Grimaldi,Marlucia Bonifacio Martins,Ana Carolina Rendeiro,Edmundo Barrios,Patrick Lavelle +7 more
TL;DR: In this paper, the origin of aggregates separated according to visual criteria could be determined by comparing their specific organic matter signatures assessed by Near Infrared Spectrometry (NIRS) to signatures of biogenic structures produced by soil ecosystem engineers living in the same soil.
