Effects of Niche Marginality on Hotter‐Drought Tree Mortality in Angiosperms and Gymnosperms

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 9, September 2025.
ABSTRACT Aim Current observations of global tree mortality events associated with drought raise concerns about climate change risks to forests' dynamics and function. It is unclear which forests are more susceptible to pulses of mortality under further changing climates.

Biomass accumulation in natural Nothofagus pumilio stands Fireland-Chile

open access: yesForest Systems, 1995
The aim of this study was to analize the biomass accumulations in two Lenga (Nothofagus pumilio) natural forests, growing at 250 meters above sea level in Tierra del Fuego-Magallanes, Chile. Allometric equations were developed, based on destructive sampling (91 trees) in order to estimate the biomass.

A Qualitative Methodologic Proposal to describe regeneration on Nothofagus pumilio forests

open access: yesForest 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 ...

The First Firn Core From the Cordillera Darwin Icefield: Implications for Future Ice Core Research

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 12, 28 June 2025.
Abstract The Southern Hemisphere westerly winds (SHWWs) (45–65°S) are important regulators of the Southern Hemisphere climate. The scarcity of observational records at the core of the wind belt hinders our understanding of the environmental impact and long‐term variability of the westerly winds.
