Efecto del ácido indolbutírico, del tipo de la cama de arraigamiento, del substrato, y del árbol madre en la capacidad de arraigamiento de estacas de Nothofagus glauca (Phil.) Krasser - Santelices, Rómulo; Cabello, Angel
Nothofagus glauca (Phil.) Krasser is a tree of conservation concern that is characteristic for the mesomorphic
zone of Chile. Techniques for vegetative propagation of this species are not well known. In this study, the
rooting capacity of stem cuttings was investigated. Using vegetative material collected in November 1995 and
1997, the effect of indolebutyric acid (IBA = 0, 0.5, 1, and 2 %), bed rooting system (bottom heating and
without temperature control), substrate (sawdust and bark compost of Pinus radiata D. Don), and parent tree
on rhizogenesis was analyzed. Experiments were conducted for 2.5-4 months in a greenhouse. The greenhouse
was equipped with an automatic misting...

Taxonomic and biogeographical status of guanaco Lama guanicoe (Artiodactyla, Camelidae) - González, Benito; Palma, R. Eduardo; Zapata, Beatriz; Marín, Juan C.
1. We review the status of the four currently recognized guanaco Lama guanicoe subspecies, and provide information about their taxonomy and distribution. The success of guanaco in inhabiting open habitats of South America is based mainly on the flexibility of their social behaviour and ecophysiological adaptations to harsh environments.
2. Lonnberg described the first subspecies, L. g. cacsilensis, at the beginning of the 20th century. Forty years later Krumbiegel described L. g. voglii, based on skull measurements and pelage colouration. The other two subspecies, L. g. huanacus and L. g. guanicoe, were classified as subspecies by Krumbiegel based on pelage colouration...
