Banks of algal microscopic forms: hypotheses on their functioning and comparisons with seed banks

Autor: Alicia J. Hoffmann, Bernabé Santelices

Publikováno v: Marine Ecology Progress Series. 79:185-194

It has been proposed that a 'bank of microscopic forms' functions as a survival mechanism for benthc macroalgae, m some ways analogous to the 'seed bank' of terrestrial plants. Four aspects related to this hypothesis are examined here, namely (1) ori

Vegetation change in large clearings: Patterns in the Chilean matorral

Autor: Eduardo R. Fuentes, Alicia J. Hoffmann, María C. Alliende, Aldo Poiani

Publikováno v: Oecologia. 68:358-366

Previous studies have shown that in Chile the so called mature matorral can have the form of either a continuous matrix of shrubs (wet sites) or of multispecific clumps of shrubs (dry sites). After clearing, sites are known to be initially covered by

Growth pattern and seasonal behavior of buds of Colliguaya odorifera, a shrub from the Chilean mediterranean vegetation

Autor: Alicia J. Hoffmann, Adriana E. Hoffmann

Publikováno v: Canadian Journal of Botany. 54:1767-1774

Colliguaya odorifera Mol., an euphorbian shrub, grows among the sclerophyllous scrub of central Chile. The growth pattern and seasonal behavior of the floral and vegetative buds are analyzed, with special reference to the climatic conditions (cool hu

Satureja gilliesii, a poikilohydric shrub from the Chilean mediterranean vegetation

Autor: Gloria Montenegro, Adriana E. Hoffmann, Maria E. Aljaro, Alicia J. Hoffmann

Publikováno v: Canadian Journal of Botany. 57:1206-1213

Satureja gilliesii is a small shrub, representative of the Chilean mediterranean vegetation found on arid slopes and on partially degraded soils. It has two types of branches: dolichoblasts with winter leaves and brachyblasts with smaller spring leav

TEMPERATURE, PHOTOPERIOD AND LIGHT INTERACTIONS ON GROWTH AND FERTILITY OF GLOSSOPHORA KUNTHII (PHAEOPHYTA, DICTYOTALES) FROM CENTRAL CHILE1

Autor: M. Elena Malbrán, Alicia J. Hoffmann

Publikováno v: Journal of Phycology. 25:129-133

Excised ligulae of Glossophora kunthii from central Chile were cultured of temperatures of 5–25° C, photoperiods of 16:8 and 8:16 h LD cycles, with photon irradiances of 10 and 50 μmol · m−2· s−1. Growth of the ligulae, number of fertile li

THE ANNUAL RHYTHM OF CAMBIAL ACTIVITY IN TWO WOODY SPECIES OF THE CHILEAN 'MATORRAL'

Autor: Maria E. Aljaro, Alicia J. Hoffmann, Guacolda Avila, Jochen Kummerow

Publikováno v: American Journal of Botany. 59:879-885

A B S T R A C T The annual rhythm of cambial activity is compared in Proustia cuneifolia and Acacia caven, two typical shrubs of the "matorral" in the semiarid region of central Chile. Proustia, a drought deciduous shrub, shows a typical desert cambi

Morphology and Histology of Trevoa trinervis (Rhamnaceae), a Drougth Deciduous Shrub from the Chilean matorral

Autor: Alicia J. Hoffmann

Publikováno v: Flora. 161:527-538

Summary The ramification system and the histological structures of Trevoa trinervis, a shrub from the Chilean matorral, are studied. The axilar bud system of the principal branches is constituted by a summer bud that originates a thorn-shoot in the f

Publikováno v: Oecologia. 69(2)

Interactions between a Chilean mistletoe, quintral (Tristerix tetrandrus, Loranthaceae) and its potential host plants were studied at a site with mediterranean type climate. The results show that the distribution of T. tetrandrus is related to the be
