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 ...
Feasible biotechnological and bioremediation strategies for serpentine soils and mine spoils
(Pontificia Universidad Católica de Valparaíso, 1999)
Whether in life or in death: fresh perspectives on how plants affect biogeochemical cycling
(Wiley, 2015-11)
1. Plants have numerous impacts on biogeochemical cycling across both aquatic and terrestrial ecosystems. These effects extend well beyond the critical role of carbon (C) fixation through photosynthesis that provides the ...
Micorrizas arbusculares y endófitos septados oscuros en tres especies de Rosáceas de ArgentinaArbuscular mycorrhizal and dark septate endophytes in three species of Rosaceae Argentina
(Fundación Miguel Lillo, 2014)
Las especies de la familia Rosaceae son susceptibles a la colonización por micorrizas arbusculares. Este trabajo describe los tipos morfoanatómicos de colonización micorrícica arbuscular presente en el sistema radical de ...
Crop rotation and seasonal effects on fatty acid profiles of neutral and phospholipids extracted from no-till agricultural soils
(Wiley Blackwell Publishing, Inc, 2015-03)
Analysis of phospholipids (PLFA) and neutral lipids fatty acids (NLFA) was used to characterize no-till productive agricultural soils associated with different crop rotation levels, replicated across a 400 km transect in ...
Competition and growth of a grass–legume mixture fertilised with nitrogen and phosphorus: effect on nutrient acquisition, root morphology and symbiosis with soil microorganisms
(Csiro Publishing, 2016-06)
Achieving a fast initial growth is crucial for legumes because grasses grow more rapidly and compete much better with forbs. In a pot experiment with a nutrient-deficient soil, we added nitrogen (N), phosphorus (P) and N ...
Large-scale fungal diversity assessment in the Andean Yungas forests reveals strong community turnover among forest types along an altitudinal gradient
(Wiley Blackwell Publishing, Inc, 2014-04)
The Yungas, a system of tropical and subtropical montane forests on the eastern slopes of the Andes, are extremely diverse and severely threatened by anthropogenic pressure and climate change. Previous mycological works ...
Micorrização e crescimento de progênies de hymenaea stignocarpa mart. ex. Hayne em subsolo de área degradada degraded area
(2013-04-11)
In tropical ecosystems, little is known about the relationship between arbuscular mycorhizal fungi (AMF) and the host genetic variability, especially among tree species. This study aimed to examine the response of 19 ...
Common bean (Phaseolus vulgaris L.) yield response to chemical and biological fertilization in different localities of Colombia
(Universidad Nacional de Colombia - Sede Medellín - Facultad de Ciencias Agrarias, 2018-09-01)
The research was carried out in 2015 in five bean producing locations in Colombia. The objective was to evaluate the effect of different treatments of chemical and biological fertilization on the yield of climbing and bush ...
