On the relationship between Photosystem II thermotolerance and irreversible heat damage in leaves of Rhizophora mangle

open access: yesPlant Biology, EarlyView.
Temperature‐F0 fluorescence curves of Rhizophora mangle leaves demonstrate that Tcrit, the temperature at which F0 begins to rise, is unrelated to tissue necrosis; irreversible leaf damage starts to occur at significantly higher temperatures where fluorescence emission is maximal. Abstract Global temperatures are on the rise and may, together with more

Climate Sensitivity and Drought Legacy of Tree Growth in Plantation Forests in Northeast China Are Species- and Age-Dependent

open access: yesRemote Sensing
The occurrence, frequency, and severity of drought are accelerating due to global warming. Understanding the vulnerability of plantation forests to climate change, particularly to drought events, is critical to revealing the underlying mechanisms of tree

A Laser Photoacoustic Analysis of Residual CO2 and H2O in Larch Stems

open access: yesBiosensors, 2014
Every so often, the results obtained from investigations into the effects of varying environmental conditions on the tree growth rate at the same sites and on the change in the carbon balance in plants, using traditional methods, are found to differ ...

Reversal of economic integration: evidence from European Union enlargement

open access: yesThe Scandinavian Journal of Economics, EarlyView.
Abstract Empirical models of trade agreements implicitly assume that withdrawal from a trade agreement has an equal and opposite trade effect as accession (i.e., symmetry). With increasing opposition to international economic cooperation, it becomes urgent to test this assumption.

Influence of plantation-type forests on forest soil fertility indicators under conditions of the Western Forest-Steppe of Ukraine

open access: yesНаукові праці Лісівничої академії наук України, 2019
There is a close interaction between plantations of different composition and soil fertility which can be adjusted by changing the species involved in the stand composition. The issue is particularly relevant from the point of view of the introduction of

Living in the Mycelial World

open access: yesTopics in Cognitive Science, EarlyView.
Abstract This manuscript documents a systematic ethnomycological analysis of ethnographic archives. Focusing on texts describing human–fungi interactions, I conduct a global, cross‐cultural review of mushroom use, covering 193 societies worldwide. The study reveals diverse mushroom‐related cultural practices, emphasizing the significance of fungi ...

Slope mediates drought sensitivity but does not affect drought recovery for young trees along elevation gradients in temperate planted larch forests

open access: yesForest Ecosystems
Climate warming causes mountainous species to shift their distributions towards higher elevations. How elevation influences growth–climate relationship in mountain regions has been intensively investigated. However, how microtopography shapes tree growth

Larch dwarf mistletoe not found on alpine larch

open access: yes, 1995
Reports of larch dwarf mistletoe parasitizing alpine larch are based on two collections of this host/parasite combination made by J.R. Weir in Montana during the early 1900s. Examination of host material from these collections indicates that the host is western larch, not alpine larch as previously reported.

“Is This Edible Anyway?” The Impact of Culture on the Evolution (and Devolution) of Mushroom Knowledge

open access: yesTopics in Cognitive Science, EarlyView.
Abstract Mushrooms are a ubiquitous and essential component in our biological environment and have been of interest to humans around the globe for millennia. Knowledge about mushrooms represents a prime example of cumulative culture, one of the key processes in human evolution.

Automated Crossdating With a Modified Version of the Dendrochronology Program CROS

open access: yesArchaeometry, Volume 68, Issue 3, Page 311-316, June 2026.
ABSTRACT The basic principle of dendrochronology involves matching patterns of tree‐ring widths, with the objective of dating wood of unknown age. The various crossdating procedures rely on statistical methods. The legacy CROS program written in FORTRAN IV contains algorithms, variants of which have been incorporated into modern crossdating programs ...
