Elevation-dependent tree growth response to climate in a natural Scots pine/downy birch forest in northern Sweden. [PDF]

Plant Environ Interact
Changes in tree growth trends in protected natural forests in northern Fennoscandia can serve as early indicators of the impact of global warming on natural ecosystems. We took increment cores from a total of 592 Scots pine and downy birch trees along an elevational gradient, calculated the basal area increments and investigated trends in climate ...

The Historical Development of Large‐Scale Paleoclimate Field Reconstructions Over the Common Era

Reviews of Geophysics, Volume 61, Issue 4, December 2023., 2023
Abstract Climate field reconstructions (CFRs) combine modern observational data with paleoclimatic proxies to estimate climate variables over spatiotemporal grids during time periods when widespread observations of climatic conditions do not exist. The Common Era (CE) has been a period over which many seasonally‐ and annually‐resolved CFRs have been ...

SNOTEL, the Soil Climate Analysis Network, and water supply forecasting at the Natural Resources Conservation Service: Past, present, and future

JAWRA Journal of the American Water Resources Association, Volume 59, Issue 4, Page 585-599, August 2023., 2023
Abstract The Snow Survey and Water Supply Forecasting (SSWSF) Program and the Soil Climate Analysis Network (SCAN) of the United States Department of Agriculture's Natural Resources Conservation Service (NRCS) generate key observational and predictive information for water managers.

Forest edge effects on moss growth are amplified by drought

Ecological Applications, Volume 33, Issue 4, June 2023., 2023
Abstract Forest fragmentation increases the amount of edges in the landscape. Differences in wind, radiation, and vegetation structure create edge‐to‐interior gradients in forest microclimate, and these gradients are likely to be more pronounced during droughts and heatwaves.

Competitive interactions under current climate allow temperate tree species to grow and survive in boreal mixedwood forest

Ecography, Volume 2023, Issue 5, May 2023., 2023
With climate change, climatic optima are shifting poleward more rapidly than tree migration processes, resulting in a mismatch between species distributions and bioclimatic envelopes. Temperate hardwood tree species may take advantage of the release of climate constraints and forest management to migrate into the boreal forest.

Using machine learning on tree‐ring data to determine the geographical provenance of historical construction timbers

Ecosphere, Volume 14, Issue 3, March 2023., 2023
Abstract Dendroclimatology offers the unique opportunity to reconstruct past climate at annual resolution and wood from historical buildings can be used to extend such information back in time up to several millennia. However, the varying and often unclear origin of timbers affects the climate sensitivity of individual tree‐ring samples.

Frequencies of Multivariate Air Masses Drive Tree Growth

Journal of Geophysical Research: Biogeosciences, Volume 128, Issue 3, March 2023., 2023
Abstract Midlatitude surface meteorological conditions are embedded within—and affected by—synoptic‐scale systems, including the movement and persistence of air masses (AMs). Changes in AM frequencies (number of daily occurrences) over the past several decades could have large effects on ecosystems: each organism is exposed to the synergistic effects ...

Evaluation of Different Pooling Methods to Establish a Multi-Century δ¹⁸O Chronology for Paleoclimate Reconstruction

Geosciences, 2019
To develop multi-century stable isotope chronologies from tree rings, pooling techniques are applied to reduce laboratory costs and time. However, pooling of wood samples from different trees may have adverse effects on the signal amplitude in the final ...

Detrending ability of several regression equations in tree-ring research: a case study based on tree-ring data of Norway spruce (Picea abies [L.])

Journal of Forest Science, 2011
The aim of this study was to investigate tree-ring width variability and to distinguish groups of trees with similar growth trends in order to study tree growth responses to various stand and site conditions. The methods of cluster analysis were employed
