The influence of canopy-layer composition on understory plant diversity in southern temperate forests

Forest Ecosystems, 2017
Background Understory plants represents the largest component of biodiversity in most forest ecosystems and plays a key role in forest functioning. Despite their importance, the influence of overstory-layer composition on understory plant diversity is ...

Paleoseismic Evidence of Recent Co‐Seismic Ruptures in Western Tierra del Fuego, Chile

Tectonics, Volume 45, Issue 8, August 2026.
Abstract The Magallanes‐Fagnano fault (MFF) in Tierra del Fuego (TDF) is a major left‐lateral transform boundary between the South American and Scotia plates. While surface ruptures associated with the 1949 earthquakes have been documented in Argentina east of the Fagnano Lake, their extension to the west remained uncertain.

Temperate tree species show cross‐tolerance to heat, drought, and late spring‐frost stress

New Phytologist, Volume 251, Issue 4, Page 1625-1630, August 2026.
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.

Biological legacies influence seedling survival and growth in post‐fire restoration of Patagonian Nothofagus pumilio forests

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
In post‐fire subantarctic forests of Torres del Paine National Park, nucleation‐based reforestation of Nothofagus pumilio was evaluated over 5 years to assess how the identity, proximity, and lateral coverage of biological legacies influence seedling survival and growth.

A cost‐effective DNA extraction protocol for long‐read sequencing in non‐model plants

Applications in Plant Sciences, Volume 14, Issue 4, July-August 2026.
Abstract Premise Third‐generation sequencing has revolutionized genomics, enabling in‐depth analysis of genome sequence, structure, and epigenetic features. Yet, extracting high‐quality DNA for long‐read sequencing remains a bottleneck—particularly in non‐model plants, such as mature trees growing in natural environments, which often contain abundant ...

Recovery of Seed Quality and Germination Success Following Severe Wildfires in Araucaria araucana Forests of the Southern Andes

Ecology and Evolution, Volume 16, Issue 7, July 2026.
We assessed post‐fire germination of Araucaria araucana in the southern Andes and found that seed viability and germination increased markedly (from 65% to 90%) between 1 and 8 years after a severe wildfire. Improved germination at longer time‐since‐fire reflects a recovery of reproductive capacity in this ecologically and culturally significant ...

Richness and Density of Birds in Timber Nothofagus pumilio Forests and their Unproductive Associated Environments

Biodiversity and Conservation, 2005
Research on forest management impact focuses mainly on timber stands, and leaves out the unproductive forest environments. These stands are spatially mixed with timber forests. The objective was to evaluate richness and density of birds in timber Nothofagus pumilio forests and their unproductive associated environments, and discuss forest management ...
