Atmosphere, 2022 Previous dendroclimatic studies have examined the relationship between total precipitation amounts and tree radial growth in the southeastern USA, yet recent studies indicate that specific precipitation event types and rainfall intensities influence ...

N=1 Supersymmetric $SU(2)^r$ Moose Theories [PDF]
, 2002 We study the quantum moduli spaces and dynamical superpotentials of four dimensional $SU(2)^r$ linear and ring moose theories with $\mathcal{N}=1$ supersymmetry and link chiral superfields in the fundamental representation.

Using longitudinal survival probabilities to test field vigour estimates in sugar maple (Acer saccharum Marsh.) [PDF]
, 2008 Tree mortality is a major force driving forest dynamics. To foresters, however, tree mortality is often considered a loss in productivity. To reduce tree mortality, silvicultural systems, such as selection cuts, aim at removing trees that are more likely

Recent enhanced high-summer North Atlantic Jet variability emerges from three-century context
Nature Communications, 2018 Long-term records of jet stream variability are needed to place recent mid-latitude extreme weather events into a historical context. Here, using tree-ring records from Europe, the authors reconstruct variability in the latitudinal position of the high ...

Nonannual tree rings in a climate-sensitive Prioria copaifera chronology in the Atrato River, Colombia [PDF]
, 2017 In temperate climates, tree growth dormancy usually ensures the annual nature of tree rings, but in tropical environments, determination of annual periodicity can be more complex.

A narrow window of summer temperatures associated with shrub growth in Arctic Alaska
Environmental Research Letters, 2020 Warming in recent decades has triggered shrub expansion in Arctic and alpine tundra, which is transforming these temperature-limited ecosystems and altering carbon and nutrient cycles, fire regimes, permafrost stability, land-surface climate-feedbacks ...
