Red foxes enhance long‐term tree growth near the Arctic treeline

Ecosphere, 2022
Recent climate warming is expected to increase tree growth and productivity, substantially altering ecological function and boundaries in northern ecosystems.

Provenance Variation in Functional Traits of European Forest Trees: Meta‐Analysis Reveals Effects of Taxa and Age Despite Critical Research Gaps

Ecology and Evolution, Volume 15, Issue 8, August 2025.
This meta‐analysis on intraspecific variation in European trees studied the frequency of provenance variation, provenance–environment interaction, clinal variation along the climate of origin or transfer distance. While identifying trait group specific patterns of variation, research gaps have been identified in terms of age and geographical ...

Long‐Term Temporal Divergence in Post‐Drought Resilience Decline Between Deciduous and Evergreen Tree Species

Global Change Biology, Volume 31, Issue 7, July 2025.
Severe drought increasingly threatens the resilience of forest biomes worldwide. Using a tree‐ring database from Canadian forests, encompassing 40,147 trees across 4558 plots and 23 species, we analyzed temporal and spatial patterns of drought resilience.

White spruce presence increases leaf miner effects on aspen growth in interior Alaska

Frontiers in Forests and Global Change
Alaska’s boreal forests are experiencing rapid changes in climate that may favor deciduous-dominated systems, with important implications for global biogeochemical and energy cycles. However, aspen (Populus tremuloides Michx.) has experienced substantial

Advance, steadfast, retreat? Growth and establishment of white spruce seedlings at treelines in Alaska

Ecosphere, Volume 16, Issue 6, June 2025.
Abstract Range dynamics of tree species are largely driven by seedling establishment and survival, mainly at and beyond current treelines. Although numerous studies document the growth of mature white spruce (Picea glauca) trees in Alaska, research on seedling establishment and growth, particularly dendroecological studies addressing climate ...

Forest Structure and Fire History at Lake Arcadia, Oklahoma County, Oklahoma (1820–2014)

Oklahoma Native Plant Record, 2015
Evidence indicates that the structure of Oklahoma Cross Timbers forests are in transition due to changing climate, land-use patterns, and fire suppression efforts.

Grazing Affects Soil Organic Carbon Stocks Directly and Indirectly Through Herbaceous Species Diversity in Sahelian Savanna Ecosystems

Land Degradation &Development, Volume 36, Issue 10, Page 3490-3498, June 2025.
ABSTRACT The impact of livestock grazing on soil organic carbon (SOC) stocks in the Sahel has been poorly documented due to a lack of data from different grazing intensities. This study evaluated SOC stocks under four grazing intensities within 0–30 cm soil depth in dry savanna ecosystems of Senegal.

Urban Tree Growth and Drought Responses Show Evidence of Climate Resilience

Global Change Biology, Volume 31, Issue 6, June 2025.
Urban trees face increasing risks from climate change, including drought and heatwaves, which threaten their growth and survival. By studying 10 tree species across seven Australian cities, we found that local climate strongly influences tree growth, and that some species are well adapted to urban climates.

Editorial note for the special issue on ‘Tropical Dendroecology’ [PDF]

Trees, 2010
It is not very long ago that tree-ring studies on tropical trees were in their pioneering stage, being regarded as exceptional studies. Since dendroecology evolved in the temperate climate zones, the majority of dendroecologists trusted in the paradigm that trees growing in tropical climates do not exhibit annual growth rings and hence are not suitable

Exploring Relationships among Tree-Ring Growth, Climate Variability, and Seasonal Leaf Activity on Varying Timescales and Spatial Resolutions

Remote Sensing, 2017
In the first section of this study, we explored the relationship between ring width index (RWI) and normalized difference vegetation index (NDVI) time series on varying timescales and spatial resolutions, hypothesizing positive associations between RWI ...
