Does vegetation cover suppose gully erosion stabilization?
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpena
The present research is addressed to study the evolution of vegetation cover on gully sidewalls and its influence on sediment production due to gully erosion and on gully walls’ stabilization. A sample gully system of the ... -
Double stranded RNAs in the mushroom virus X complex of Agaricus bisporus

Effect of topography on retreat rate of different gully headcuts in Bardenas Reales area (Navarre, Spain)
Campo-Bescós, Miguel
; Álvarez-Mozos, Jesús ; Casalí Sarasíbar, Javier ; Giménez Díaz, Rafael (Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
Contribución a congreso / Biltzarrerako ekarpena
In Northeast Spain, gullying is a widespread phenomenon. This type of erosion is especially intense in Bardenas Reales (Navarre) where at least two major typical kinds of gully headcut are present. A first group developed ... -
Effectiveness of palm and bamboo geotextiles in reducing concentrated flow erosion
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpena
Rills and gullies, caused by concentrated flow erosion, represent an important sediment source in many environments (Poesen et al., 2003). Studies indicate that vegetation can be very effective in controlling gully ... -
Effects of slope processes and management in gullying
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpena
Most erosion studies have been typically done in rill and interrill areas because the complexity of gullies and their large size have made their study very difficult. Morgan (1979) and Hudson (1985) define gullies as water ... -
Enzymatic characterization of a monokaryon population of the edible mushroom, Pleurotus ostreatus with a view to genetic improvement
Terrón, María del Carmen; López, María; Carbajo, José M.; Pisabarro de Lucas, Gerardo ; Ramírez Nasto, Lucía ; González Aldo, E. (Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2006)
Contribución a congreso / Biltzarrerako ekarpena
In this work the lignocellulolytic enzymes produced by the edible mushroom Pleurotus ostreatus var. florida were studied. The objective was to know their relationship with the degradation of the biopolymers present in ... -
Ephemeral gullies: to till or not to till?
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpena
While the perceived magnitude of ephemeral gully erosion may be masked after gullies are repaired, the action of plowing in these channels reduces topsoil thickness and crop productivity over a much wider area than the ... -
Ephemeral gully erosion research: processes and modeling
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpena
The USDA Natural Resources Conservation Service (NRCS) defines ephemeral gullies as small channels that can be filled in by normal tillage operations only to reform in the same location by subsequent runoff events. Ephemeral ... -
Ephemeral gully headcut development and migration in stratified soils
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpena
The objectives of the current study were: (1) to quantify the effect of an erosion resistant (ER) soil layer placed at various depths within a soil profile on headcut development and migration; and (2) to assess the ... -
Erosion processes at the gully scale: observations, quantification and interpretation of field data from the Draix laboratory
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpena
In the Southern French Alps, the black marls formation covers a large area and is highly susceptible to weathering and erosion. It has a badlands topography and is subject to high solid transport, bringing high sediment ... -
Estimating sediment yield from gully erosion using easily measurable morphometric characteristics in Darehshahr region, south of I.R. Iran
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpena
A case study was conducted in a part of Ilam Province, I.R. Iran, to establish a reliable model for estimating sediment yield from gully erosion. The attempt was satisfactory and led to an applicable model whose input could ... -
Evaluating airborne laser scanning for gully erosion detection and baseline mapping in the Fitzroy catchment, QLD, Australia
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpena
Australia’s climate and land management practises have resulted in an increased threat to land condition and water quality through sediment transported by gully erosion. The Fitzroy River catchment is located in Queensland ... -
Evidence for a 200 gene ribosome and rRNA biosynthesis (rrb) regulon in fungi
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2006) Contribución a congreso / Biltzarrerako ekarpena
Two challenges of the post genomic era are 1) the need to assign functions to as yet uncharacterized gene products, and 2) the requirement to understand how the expression profiles of large sets of genes are regulated ... -
Expression of GFP and DsRed in the homobasidiomycete Schizophyllum commune
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2006) Contribución a congreso / Biltzarrerako ekarpena
Expression of GFP and DsRed was studied in the homobasidiomycete Schizophyllum commune. CGFP or sGFP fused to the SC3 promoter resulted in similar steady state mRNA levels. These levels were considerably lower than that ... -
