Impact of powerful volcanic eruptions and solar activity on the climate above the Arctic Circle

Geofísica Internacional, 2018
En este trabajo, se evalúa la respuesta del crecimiento de los árboles en la región polar (Península de Kola y la Laponia de Finlandia) a las erupciones volcánicas más potentes (VEI > 4) durante un periodo de 1445-2005.

Decay stages of Jurassic wood debris from Scotland: evidence for the coevolution of fungal rot, arthropods and the nurse log strategy

New Phytologist, Volume 248, Issue 3, Page 1557-1571, November 2025.
Summary A key feature of extant conifer forests is the high percentage of seeds that germinate and establish on dead wood; in some forests, this can exceed 90%. This deadwood can act as an ideal nursery for young tree species, leading to this type of seedbed being termed ‘nurse logs’.

Densidad y dimensiones de la fibra de Gmelina arborea en árboles de rápido crecimiento en Costa Rica: relación con el rango de de crecimiento [PDF]

, 2007
The objective of this research was to determine growth rate effects measured in tree diameter on wood density parameters (mean, minimum, maximum and intra-ring variation) and in fiber dimensions (wall thickness, fiber width, lumen diameter and fiber ...

Unraveling water pathways and sources in leafless maples during early spring sap ascent

New Phytologist, Volume 247, Issue 3, Page 1172-1185, August 2025.
Summary Maple trees repair cold‐induced embolism by generating positive stem pressure during their leafless state, altering sap transport in ways that remain poorly understood. This xylem pressure also drives sap exudation, enabling maple sap harvest for syrup production.

Intraspecific variation in plant–fungal interactions across tidal elevation in a salt marsh

New Phytologist, Volume 247, Issue 4, Page 1875-1886, August 2025.
Summary Interspecific interactions vary depending on environmental and genetic factors, with intraspecific variation potentially altering these relationships. Specifically, intraspecific variation within host plants and their endosymbionts may affect above‐ and belowground interactions depending on environmental conditions.

Climate warming promotes growth in Himalayan alpine cushion plants but threatens survival through increased extreme snowfall

New Phytologist, Volume 247, Issue 1, Page 115-127, July 2025.
Summary Climate warming stimulates growth and reproduction in cold‐adapted plants but also leads to extreme weather events that may hinder their performance. We examined these predictions in the cold‐arid Himalayan subnival zone at 5900 m, where unprecedented warming and extreme snowfalls occurred over the past three decades.

Opposing seasonal trends in source water and sugar dampen intra‐annual variability in tree rings oxygen isotopes

New Phytologist, Volume 247, Issue 1, Page 97-114, July 2025.
Summary Variations of oxygen isotopes δ18O in tree rings provide critical insights into past climate and tree physiological processes, yet the mechanisms shaping the intra‐annual δ18O signals remain incompletely understood. To address this gap, we investigated how seasonal changes in source water, leaf water, and sugars influence δ18O recorded along ...
