We present the first network of tree-ring chronologies for co-occurring Nothofagus nervosa and Nothofagus obliqua in Argentina. Using standard dendrochronological techniques, we developed seven tree-ring width chronologies for each species, encompassing their E-W distribution along a precipitation...

Climate models for North Patagonia in Argentina project dryer conditions, due to a decrease in mean precipitation combined with an increase in mean temperatures. The temperate mixed Nothofagus forest, which exists along a steep precipitation gradient, could be directly impacted. For this study, we...

Arboreal species of the genus Prosopis L. have played an important role in the development of tree-ring research in arid and semi-arid ecoregions of South America. Given the distribution of Prosopis across a broad precipitation gradient from 0 to 2000 mm y-1 and its unique role as a phreatophyte,...

Arid and semiarid environments dominate the Earth's surface and are very vulnerable to global change. Chañar (Geoffroea decorticans) and brea (Parkinsonia praecox) are two ubiquitous woody species of these environments. They grow in degraded forests, strongly modified areas and as a main component...

Araucaria araucana is a dioecious evergreen conifer endemic from temperate forests of south Argentina and Chile. It is a long-lived species (maximum age > 1000 years), and it presents a high potential for tree-ring based climate reconstructions. However, the species' dioecious habit can result...

Since the mid-twentieth century, a conflict has developed on a national scale between the provinces of La Pampa and Mendoza (Argentina), producing a so-called decrease in the amount of water from the Atuel river. The main objective of the study is to try to reconstruct the hydrological conditions...

Dendrochronological methods have been widely used to determine the date of construction and provenance of shipwrecks. Despite a large number of shipwrecks, the application of dendroarchaeological techniques is relatively incipient in the coasts of South America. This paper presents the results of a ...

Background and Aims: The vulnerability and responsiveness of forests to drought are immensely variable across biomes. Intraspecific tree responses to drought in species with wide niche breadths that grow across contrasting climatically environments might provide key information regarding forest...

Climate forcings determine the episodic occurrence of local climate anomalies that trigger the occurrence of masting events (massive, synchronized and intermittent seed production by perennial plants). This suggests some kind of phase-locking of the reproductive cycles of individual plants to the...

A pronounced seven-year cycle is one of the most prominent features of many Fuegian and southern Patagonian Nothofagus pumilio tree-ring width chronologies. However, the source of this variability is still unclear. Here we provide multiple lines of evidence that suggest this phenomenon comes from...
