Timeline of leaf and cambial phenology in relation to development of initial conduits in xylem and phloem in three coexisting sub-Mediterranean deciduous tree species [PDF]

, 2020
It is unclear how the anticipated climate change will affect the timing of phenology of different tree organs/tissues and thus the whole-tree functioning.

Temperature and nutrient availability influence radial growth of Picea abies at opposite slopes in a treeline ecotone [PDF]

Biogeosciences
Treeline ecotones in complex mountain landscapes are exposed to pronounced differences in irradiation and soil nutrient availability. Different amounts of nutrients and direct solar energy can influence tree stem growth, especially in lower parts of a ...

Bark‐associated yeasts and their potential role as tree carbon sink at the treeline of the southern Andes

Plant Biology, Volume 28, Issue 6, Page 2054-2064, October 2026.
In the southern Andes, Nothofagus pumilio shows elevational decreases in the concentrations of carbon reserves which are the food of bark‐associated yeasts, suggesting that competition for carbohydrates between tree growth and bark‐associated yeasts may cause carbon shortages.

Woody Vegetation Dynamics Beyond the Treeline: Identifying Limiting Processes and Their Tipping Points

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
Illustration of temporal trends in Arctic and alpine woody vegetation under changing growth conditions (summer temperature and winter snowpack). Upper panel: example of shrub expansion in southern France (photograph included). Greening is detected via increasing NDVI (Normalized Difference Vegetation Index).

May Temperature Drives Cambial Resumption in the Boreal Black Spruce [PDF]

, 2022
The timings of the onset and ending of xylogenesis define the time window when environmental conditions are suitable for xylem formation. The relationship between the occurrence of xylem phenological events and the related climatic factors is critical to

Portulaca abscondita (Portulacaceae, Caryophyllales), a new microendemic species from Monte Azul, Minas Gerais, Brazil

Nordic Journal of Botany, Volume 2026, Issue 9, September 2026.
Portulaca (Portulacaceae) is a cosmopolitan genus with centers of diversity in Africa and South America. In Brazil, 22 species are recognized, most occurring in xerophytic environments of the Cerrado, particularly in Campos Rupestres. These rocky montane habitats, especially in northern Minas Gerais state, remain undercollected despite their high ...

Climate-growth relationships at different stem heights in silver fir and Norway spruce [PDF]

, 2012
We investigated the effect of climate on variations in annual ring-area increment along the stem of dominant silver fir (Abies alba Mill.) and Norway spruce (Picea abies (L.) Karst.) trees in the Black Forest, southwestern Germany, to test the hypothesis

Establishing Baseline Information for the Risk of Flatheaded Borer Attack in Specialty Tree Crops Using Trapping and On‐Farm Surveys

Journal of Applied Entomology, Volume 150, Issue 8, Page 1088-1101, September 2026.
ABSTRACT Flatheaded borers (Coleoptera: Buprestidae) are largely xylophagous insects. Larvae of flatheaded borers tunnel into the trunks of trees, with boring and feeding damage eventually appearing on the surface as discolored bark, sunken areas, bark splits or bark sloughing.
