Topographic influences on ring widths of trees and shrubs across alpine treelines in southwest Yukon
Growth responses of trees and shrubs to climate often exhibit unexplained variation in alpine regions, making it difficult to predict how they will respond to future changes in climate.

Progress in isotope dendroclimatology
Numerous studies have demonstrated the potential of stableisotopes in tree rings for quantitative terrestrial palaeoclimaticreconstruction (Ramesh et al., 1986; Heaton, 1999; Switsur andWaterhouse, 1998; McCarroll and Loader, 2004, 2005), but the earlywidespread application of isotope dendroclimatology has been hin-dered by laborious technical ...

Dendroclimatic Investigations of Pinus Sylvestris L. on Keretsky Archipelago Islands, the White Sea [PDF]
The radial growth dynamics of Pinus sylvestris from different habitats of Keretsky archipelago, the White Sea, was analyzed. Two tree-ring chronologies for dry pine forest and the third one for swamp habitat were built.

Abstract Climate change, expanding human ignitions, and increased fuels from fire exclusion are driving increases in area burned and fire severity in dry conifer forests of the western United States. Increasing area burned is occurring against the backdrop of a large fire deficit caused by over a century of fire exclusion.

Abstract Introduction Mining activities can lead to the formation of degraded, barren, or metal‐contaminated ecosystems. Resource‐poor ecosystems such as rocky outcrops are more sensitive to mining degradation, and their natural regeneration can be challenging due to soil erosion, lack of resources or seeds, and soil acidification.

Abstract Groundwater dating studies rely on environmental tracers to estimate residence times, but most available reliable tracers cover either short (days to decades; e.g., 222Rn, 3H/3He, 85Kr) or extended timescales (millennia to millions of years; e.g., 4He, 36Cl, 81Kr). This leaves a critical gap in age information for intermediate residence times (

Diameter growth is an important and good indicator of forest carbon production. However, size‐related changes in wood density, which are usually neglected, are critical for accurate short‐ and long‐term carbon assessments, especially in tropical humid sites.

Proxy records have provided major insights into the variability of past climates over long timescales. However, for much of the Southern Hemisphere, the ability to identify spatial patterns of past climatic variability is constrained by the sparse ...

Dendroclimatology in Fennoscandia – from past accomplishments to future potential [PDF]
Abstract. Fennoscandia has a strong tradition in dendrochronology, and its large tracts of boreal forest make the region well suited for the development of tree-ring chronologies that extend back several thousands of years. Two of the world's longest continuous (most tree-ring chronologies are annually resolved) tree-ring width chronologies are found ...
