Root studies in the Chilean matorral

  title={Root studies in the Chilean matorral},
  author={Adriana Hoffmann and Jochen Kummerow},
SummaryThe roots of matorral shrubs were excavated from an 18 m2 site of a mixed matorral stand located on a 27° NE facing slope at 1000 m elevation 40 km NNW from Santiago de Chile. The climate in this area is similar to that of the Southern Californian chaparral. The main species present were Lithraea caustica, Cryptocarya alba, Colliguaya odorifera, Mutisia retusa, and Satureja gilliesii. After harvesting the above ground biomass, the soil was washed out in 20 cm layers down to a depth of 60… 
Root biomass, root distribution and the fine-root growth dynamics of Quercus coccifera L. in the garrigue of southern France
It was hypothesized that low winter temperatures inhibit active fine-root growth in quercus coccifera L., the characteristic scrub oak of the garrigue, and the data supported the hypothesis.
Seasonal patterns of growth phenology and nutrient dynamics in four matorral shrubs in Central Chile
Chile is one of five global regions exhibiting a mediterranean-type climate regime characterized by evergreen sclerophyll shrublands. These matorral shrublands which dominate the foothills and slopes
Root distribution of a Mediterranean shrubland in Portugal
The distribution of roots of an Erica (Erica scoparia and Erica lusitanica) dominated Mediterranean maquis was studied using three different approaches: root counts on trench walls (down to 120 cm),
Growth of provenances of Cryptocarya alba during water stress and after re–watering in the nursery
This study demonstrated phenotypic variation of C. alba and the capability of the species to withstand and recover from water stress and the highest performance under water restriction of northern provenances.
Vegetative responses to defoliation of two Chilean matorral shrubs
Experimental defoliation of two common matorral species Lithraea caustica and Colliguaya odorifera is reported, related to the observed position of both species in the mATORral community and their relative defoliated risks by natural and introduced herbivores.
Belowground structure and production in a Mediterranean sand dune shrub community
Belowground structure and annual production in an open Mediterranean scrub were studied on a sandy substrate which had not been harvested or exposed to fire during the last 30–40 years. Estimated
Phenorhythms and Forest Refugia
Anomalous phenoryhthms such as reiterated anthesis and annual, biennial and intermediate fruiting are recorded for evergreen oaks (Quercus sect. Sclerophyllodrys: Q. ilex, Q. coccifera s.l. and
Influence of provenance origin on the early performance of two sclerophyllous Mediterranean species established in burned drylands
In outplanting sites with Mediterranean-type climates that have been damage by severe fire, selections based on larger diameter seedlings, especially for Q. saponaria and from interior and pre-Andean provenances, will likely improve out Planting success.
Variability in water use by phreatophytic Banksia woodland vegetation of the Swan Coastal Plain, Western Australia
Seasonal changes erJst in sr.urce-water utilisation by Banksia woodland species overlying a shallow aquifer on the Swan Coastal Plain in Western Australia These were studied to identifY the


Root systems of chaparral shrubs
It is hypothesized that the shallow soil at the excavation site impeded a clear depth zonation of the different root systems, and the fine root density under the canopy was significantly higher than in the unshaded area.
Distribution and Peculiarity of Mediterranean Ecosystems
The lands of mediterranean scrub or chaparral climate and the ecosystems that have developed in them must be defined in climatic terms. If we attempt to focus on the characteristic core of a

The factual basis for three generally accepted concepts about desert vegetation is reviewed, and found wanting. The concepts must, at least, be strictly qualified. The concepts are: (1) net primary
