Regeneration and stand dynamics of Fitzroya cupressoides (Cupressaceae) forests of southern Chile’s Central Depression

open access: yesForest Ecology and Management, 2002
Several populations of Fitzroya cupressoides (Mol.) Johnst. (Cupressaceae, common name ‘‘alerce’’), a threatened, longlived conifer endemic to southern Chile and parts of Argentina, have recently been found in Chile’s Central Depression, where the species was thought to have been extirpated.

Regeneration of Fitzroya cupressoides after indigenous and non-indigenous timber harvesting in southern Chilean forests

open access: yesForest Ecology and Management, 2007
Abstract Fitzroya cupressoides (Cupressaceae) is an endemic and long-lived conifer of southern Chile and Argentina (40–43° S). This species has been subject to continuous exploitation since the 16th century, causing extensive population decline. Historically, the main labour force for the exploitation of F.

Nitrogen mineralization in epiphytic soils of an old-growthFitzroya cupressoidesforest, southern Chile

open access: yesÉcoscience, 2005
ABSTRACT Epiphytic soils derive from organic matter accumulation on trunks and canopy branches of large trees. We compared chemical and physical properties, rates of net N mineralization, and bacterial biomass carbon associated with epiphytic soils and the forest floor of an old-growth, temperate forest dominated by the long-lived Fitzroya cupressoides

Annual radiocarbon variability in southern South America recorded by Fitzroya cupressoides , AD 970–1084

open access: yesRadiocarbon
Abstract Annually resolved radiocarbon ( 14 C) records from tree rings provide a high-resolution archive for investigating short-term atmospheric 14 C variations driven by solar and cosmic activity, as well as terrestrial processes ...

Variability of foliage terpenes of Fitzroya cupressoides

Biochemical Systematics and Ecology, 1991
Abstract Foliage of 57 Fitzroya cupressoides trees from six locations in Chile was analysed for monoterpenes and sesquiterpenes. A new monoterpene, ipsdienyl acetate (2-methyl-4-acetoxy-6-methylene-octa-2,7-diene), was found. No geographic variability in monoterpene composition was evident. Three distinct sesquiterpene chemotypes were found in the

Natural regeneration of Fitzroya cupressoides in Chile and Argentina

Forest Ecology and Management, 1993
Abstract In Chile and Argentina, Fitzroya cupressoides (alerce) regeneration was sampled on a variety of sites differing in history in order to show trends in regeneration. The tree Fitzroya cupressoides grows in the cool temperate areas of South America, where its finegrained, durable wood is highly valued. The species has been widely harvested

Increased water use efficiency but contrasting tree growth patterns in Fitzroya cupressoides forests of southern Chile during recent decades [PDF]

open access: yesJournal of Geophysical Research G: Biogeosciences, 2015
Artículo de publicación ISILittle is known about how old-growth and massive forests are responding to environmental change. We investigated tree-ring growth and carbon isotopes of the long-lived and high biomass Fitzroya cupressoides in two stands ...
