Isozyme Polymorphisms Provide Evidence of Clinal Variation With Elevation in Nothofagus pumilio [PDF]
Journal of Heredity, 2003 Variable physical conditions along elevational gradients strongly influence patterns of genetic differentiation in tree species. Here, the hypothesis is tested that different growth forms of Nothofagus pumilio, which characterizes the subalpine forests in the southern Andes, will display continuous genetic variation with elevation.

Interannual variations in primary and secondary growth of Nothofagus pumilio and their relationships with climate [PDF]
Trees, 2014 The aim of this study is to evaluate the relationships between primary and secondary growth as well as the influences of climate variations on both types of growth. The relationships between apical (or primary) and radial (or secondary) growth, and climatic influences on both types of growth, were evaluated for Nothofagus pumilio ...

Forty years of silvicultural management in southern Nothofagus pumilio primary forests
Forest Ecology and Management, 2004 To achieve sustainability of a forest system it is necessary to apply appropriate silvicultural management, including preservation measures. The characterization of the status and development of the harvested stands, as well as the timber potential of the unmanaged ones, is necessary to achieve a sustainable forest management.

Tree seedlings respond to both light and soil nutrients in a Patagonian evergreen-deciduous forest.
PLoS ONE, 2017 Seedlings of co-occurring species vary in their response to resource availability and this has implications for the conservation and management of forests.

New insights into postglacial vegetation dynamics and environmental conditions of Península Avellaneda, southwest Patagonia, revealed by plant macrofossils and pollen analysis [PDF]
Mires and Peat, 2018 Reconstruction of the history of past events becomes more objective when considering an increased number of possible indicators. Combining plant macrofossil analysis with pollen analysis has the potential to give a more detailed picture of the ...

A Qualitative Methodologic Proposal to describe regeneration on Nothofagus pumilio forests
Forest Systems, 1993 It's presented a new methodologic proposal to be applied in Nothofagus pumilio forests. It arranged by relating on a qualitative way, certain regeneration variables with canopy cover and understory abundance. The field evaluation is quick and it is suggested like an accomplishment of large studies such as Forest Inventories, installation of Permanent ...

Ciencia & Investigación Forestal, 2021 Las propuestas silvícolas de los bosques de Nothofagus pumilio se basan en la apertura del dosel para estimular el crecimiento de la regeneración, cambiando la disponibilidad de agua y luz. Las plántulas sobreviven como si fueran especies tolerantes y crecen lentamente por largo tiempo (más de 20 años) bajo altas coberturas.

Temperate tree species show cross‐tolerance to heat, drought, and late spring‐frost stress
New Phytologist, EarlyView.Significant cross‐tolerance of leaf traits to heat, drought and late spring‐frost were found. (a) Turgor loss point vs lethal spring‐frost temperature. (b) Heat thermal threshold temperature vs lethal spring‐frost temperature. (c) Heat thermal threshold temperature vs turgor loss point.
