Gene expression during symbiosis in the ectomycorrhizal fungus Tricholoma vaccinum
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2006) Contribución a congreso / Biltzarrerako ekarpenaWe have identified genes specifically expressed in host interaction using an RNA fingerprinting technique.

A general sediment transport model for linear incisions
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaPrevious research has shown that the functional relationship between sediment transport and shear stress, discharge and slope is non-linear.

Of 22 F. velutipes collections examined, several were heterozygous for two indels and ... -
Gullies on mars: the debate about formative processes (keynote)
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaThe discovery of very young gully systems on Mars has occasioned a lively debate about the processes and materials involved in their formation (Malin and Edgett, 2000). The strong interest in these features results because ... -
Gully development and topographic threshold, case study: Kerman Province, southeast of I.R. Iran
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaThis research indicated that gully erosion can severely damage croplands in this area of Iran. Significant gully development occurred in the 3 years of study and the product of drainage headcut area and slope was more strongly ... -
Gully development in agricultural fields: insights from catchment scale analysis
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaThe aim of this paper is to study the combined effect of human-induced activity and the physical environmental conditions on gully development in a small agricultural catchment in Northern Israel. More specifically the ... -
Gully dynamics: initiation and morphology
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaThe paper reviews general conditions for initiation and maintenance of gullies. -
Gully erosion in central Italy: denudation rate estimation and morphoevolution of Calanchi and Biancane badlands
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaLong lasting geomorphological researches (Ciccaci et al., 1981, 1986, 2003; Del Monte et al., 2006) allowed the evaluation of denudation rates in some of the major catchments of Central Italy. It was observed a noticeable ... -
Gully erosion in mountain area of SW-China, assessed using 137Cs and 210PBEX tracers and GPS survey
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaGullies are extensively distributed in the Upper Yangtze River Basin, SW-China. But the impact of these gullies on total sediment output is still not clear because there is no reliable technique for quantifying this ... -
Gully erosion in semi-arid landscapes - monitoring of processes and development
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaThe research project MoGul (Large-scale Monitoring of Gully Erosion in Semi-Arid Landscapes) at Trier and Frankfurt University investigates the various types, development and dependencies of gullies as well as geomorphological ... -
Gully erosion on cinder cones of Tenerife (Canary Islands, Spain)
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaThe aim of this study is to observe the evolution of gully erosion on cinder cones over time and verify whether or not age is a critical factor in the level of degradation of scoria cones, independent of other factors. -
Gully erosion risk zoning: proposal of a methodology and case study
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007) Contribución a congreso / Biltzarrerako ekarpenaGullying is the most advanced, complex stage of erosion processes, with more local destructive power than other types of erosion (São Paulo, 1990).
