Mixing Eucalyptus and Acacia trees leads to fine root over-yielding and vertical segregation between species
(2013-07-01)
The consequences of diversity on belowground processes are still poorly known in tropical forests. The distributions of very fine roots (diameter <1 mm) and fine roots (diameter <3 mm) were studied in a randomized block ...
Investment in fine roots and arbuscular mycorrhizal fungi decrease during succession in three brazilian ecosystems.
(Biotropica, Washington, DC, v. 44, n. 2, p. 141-150, Marc. 2012., 2012)
Differences between root traits of early- and late-successional trees influence below-ground competition and seedling establishment.
(Journal of Tropical Ecology, v. 32, n. 4, p. 300-313, Jul. 2016., 2016)
Temporal asynchrony in fine-root biomass may contribute to shrub and grass coexistence in mixed patches
(Wiley, 2014-01-15)
We described seasonal changes in fine-root biomass of a grass and a shrub dominant species in a plant community characteristic of the arid Patagonian Monte and then we inferred to want extent the observed differences could ...
Fungal root symbionts and their relationship with fine root proportion in native plants from the Bolivian highlands above 3700 meters elevation
(Springer, 2011-07)
Here, we examined the colonization by fungal root symbionts in the cultivated Andean grain Chenopodium quinoa and in 12 species that dominate plant communities in the Bolivian Altiplano above 3,700 m elevation and explore ...
How deep can ectomycorrhizas go? A case study on Pisolithus down to 4 meters in a Brazilian eucalypt plantation
(2019-11-01)
Despite the strong ecological importance of ectomycorrhizal (ECM) fungi, their vertical distribution remains poorly understood. To our knowledge, ECM structures associated with trees have never been reported in depths ...
Fine root dynamics for forests on contrasting soils in the Colombian Amazon
(Copernicus Publications, 2009)
It has been hypothesized that as soil fertility increases, the amount of carbon allocated to below-ground production (fine roots) should decrease. To evaluate this hypothesis, we measured the standing crop fine root mass ...
Variation in biomass allocation and root functional parameters in response to fire history in Brazilian savannas
(2021-01-01)
Fire is a fundamental ecological factor in savannas because it affects vegetation dynamics and ecosystem functioning. However, the effects of fire on below-ground compartments, including biomass and root traits, and their ...
Influences of edaphoclimatic conditions on deep rooting and soil water availability in Brazilian Eucalyptus plantations
(2020-01-01)
Brazilian roundwood industry is one of the most important and productive in the world, with Eucalyptus plantations alone representing 73% of the total planted forests. Deep rooting in these plantations represents a more ...
Arbuscular mycorrhizal infection in two morphological root types of Araucaria araucana (Molina) K. KochInfección por micorrizas arbusculares en dos tipos de raíces de Araucaria araucana (Molina) K. Koch.
(Asociación Argentina de Microbiología, 2010-04)
Araucaria araucana (Molina) K. Koch is a conifer distributed in the Andean-Patagonian forests in the south of Argentina and Chile. The main objective of this work was to relate the different root classes appearing in A. ...
