Communication à un Congrès (avec Actes)
J. Romeu ; V. Pala ; O. Vinas ; R. Arbiol | Montpellier [France] : CIHEAM-IAMM | Options Méditerranéennes : Série A. Séminaires Méditerranéens, ISSN 0253-1542 | 1991Une cartographie de l'occupation du sol précise et à jour est absolument nécessaire pour une meilleure gestion des ressources agricoles et forestières. En Espagne, ces cartes appelées Mapa de Cultivos et Aprovechamientos (MCA) sont produites par[...]Bulletin : Revue

Communication à un Congrès (avec Actes)
A. Avila ; F. Roda | Zaragoza [Espagne] : CIHEAM-IAMZ | Options Méditerranéennes : Série A. Séminaires Méditerranéens, ISSN 0253-1542 | 1989The stormflow solute behaviour of a stream draining an evergreen oak forested watershed was studied. The biogeochemical response depended strongly on the watershed antecedent conditions. Under dry antecedent conditions very few runoff was produc[...]Communication à un Congrès (avec Actes)
A. Sala ; R. Picolo ; J. Piñol | Zaragoza [Espagne] : CIHEAM-IAMZ | Options Méditerranéennes : Série A. Séminaires Méditerranéens, ISSN 0253-1542 | 1989Daily courses of water potential in Quercus ilex shoots are compared during a winter day in two experimental stations located at the bottom (deeper soils) and at the top (shallow soils) of a watershed in the Serra de Prades (Tarragona, Spain). I[...]Communication à un Congrès (avec Actes)
J.J. Ibanez ; C.A. Gracia | Zaragoza [Espagne] : CIHEAM-IAMZ | Options Méditerranéennes : Série A. Séminaires Méditerranéens, ISSN 0253-1542 | 1989In this paper, a model on intraspecific competition is presented. The model is based on the concepts of areas of influence and interference. The basic hypothesis assumes that the optimisation between space occupation (maximum) and competence (mi[...]Communication à un Congrès (avec Actes)
O. Barrantes ; C.A. Gracia | Zaragoza [Espagne] : CIHEAM-IAMZ | Options Méditerranéennes : Série A. Séminaires Méditerranéens, ISSN 0253-1542 | 1989In this paper, one application of the Waring's method to estimate leaf area index, in Pinus sylvestris, is presented. Cross-sectional sapwood area was measured at different heights in four trees and was related to the leaf area sustained over ea[...]Communication à un Congrès (avec Actes)
A. Caritat | Zaragoza [Espagne] : CIHEAM-IAMZ | Options Méditerranéennes : Série A. Séminaires Méditerranéens, ISSN 0253-1542 | 1989It has been described the structure of 35 plots of different woods (beeches, oak grove, mixed woods and evergreen-oak forest) located in the Natural Park of La Garrotxa (Girona). The distribution of trees in diameter classes allow us to apprecia[...]Communication à un Congrès (avec Actes)
D. Badia ; J.M. Alcañiz | Zaragoza [Espagne] : CIHEAM-IAMZ | Options Méditerranéennes : Série A. Séminaires Méditerranéens, ISSN 0253-1542 | 1989Seasonal samples from six experimental plots of saline, gypseous and carbonated soils from arid lands of Ebro Valley, under irrigated and non-irrigated conditions, were incubated 14 days to determinate the potential nitrate production. Analytica[...]Communication à un Congrès (avec Actes)
I. Serrasolsas ; A. Ferran ; V.R. Vallejo | Zaragoza [Espagne] : CIHEAM-IAMZ | Options Méditerranéennes : Série A. Séminaires Méditerranéens, ISSN 0253-1542 | 1989Litter evolution is studied in plots of increasing age after fire: from 2 months to 30 years. During the first year, the L horizon decomposed quickly. The process was described by the decreasing of the L/F ratio during this period. From second y[...]Communication à un Congrès (avec Actes)
D. Bonilla ; F. Roda | Zaragoza [Espagne] : CIHEAM-IAMZ | Options Méditerranéennes : Série A. Séminaires Méditerranéens, ISSN 0253-1542 | 1989In March 1986, four 2x2 m treeless plots were trenched all around in an evergreen oak stand in the Montseny mountains (NE Spain). Responses to perturbation were monitorised through: 1) net mineralisation and nitrification rates measured monthly [...]Communication à un Congrès (avec Actes)
D. Rosich ; A. Castelló ; V.R. Vallejo | Zaragoza [Espagne] : CIHEAM-IAMZ | Options Méditerranéennes : Série A. Séminaires Méditerranéens, ISSN 0253-1542 | 1989The input and decomposition of litter, and the C/N ratio evolution was studied for 2 years in evergreen oak forests in the Catalonian Central Basin. The decay constant, k, obtained was 0.365. The C/N ratio had a sharp decrease in the initial 7 m[...]Communication à un Congrès (avec Actes)
J. Canadell ; F. Roda | Zaragoza [Espagne] : CIHEAM-IAMZ | Options Méditerranéennes : Série A. Séminaires Méditerranéens, ISSN 0253-1542 | 1989Root systems from 36 holm oak (Quercus ilex L.) trees were excavated, at La Castanya, Biological Station, Montseny. Allometric equations were developed to estimate below ground biomass at an experimental plot. Because of fine root losses during [...]Communication à un Congrès (avec Actes)
M.J. Lledó ; J. Piñol | Zaragoza [Espagne] : CIHEAM-IAMZ | Options Méditerranéennes : Série A. Séminaires Méditerranéens, ISSN 0253-1542 | 1989Here is the hydrological record (rainfall and streamflow) of two impervious watersheds paired and covered by a dense Quercus ilex forest. They are located in the Serra de Prades (Tarragona, Spain) where the climate is typically Mediterranean. Th[...]Ouvrage
