As climate warms, tree density at the taiga–tundra ecotone (TTE) is expected to increase, which may intensify competition for belowground resources in this nitrogen (N)-limited environment. To determine impacts of increased on N cycling and productivity, we examined edaphic properties indicative soil availability along with aboveground tree-level traits stand characteristics related carbon (C) ...

Variation in tree stem diameter results from reversible shrinking and swelling and irreversible radial growth, all processes that are influenced by tree water status. To assess the causal effects of water and temperature on stem radial variation (DeltaR) and maximum daily shrinkage (MDS), the diurnal cycle was divided into three phases: contraction, expansion and stem radius increment. Diurnal ...

We describe Lonchophyllainexpectata sp. n. from the Caatinga of Brazil. This new species can be distinguished from all known species of Lonchophylla that occur in Brazil by dental traits, cranial size, and fur colour. Specimens of Lonchophyllainexpectata have been misidentified as Lonchophyllamordax; but Lonchophyllainexpectata is a pale-venter species, similar in external appearance to Lonchop...

von Humboldt’s tree-line concept has dominated mountain ecology for almost two hundred years, and is considered a key indicator monitoring change in biome boundaries biodiversity shifts under climate change. Even though the of life zones elevation gradients are globally observed phenomenon, they have not been thoroughly explored many contexts. One such example ecotone, widely used conceptual to...

Rising temperatures associated with climate change have been shown to negatively affect the photosynthetic rates of boreal forest tree saplings at their southern range limits. To quantify the responses of ectomycorrhizal (EM) fungal communities associated with poorly performing hosts, we sampled the roots of Betula papyrifera and Abies balsamea saplings growing in the B4Warmed (Boreal Forest Wa...
