Global distribution and bioclimatic characterization of alpine biomes

open access: yesEcography, 2020
Although there is a general consensus on the distribution and ecological features of terrestrial biomes, the allocation of alpine ecosystems in the global biogeographic system is still unclear.

Distribution and population of Himalayan Marmot Marmota himalayana (Hodgson, 1841) (Mammalia: Rodentia: Sciuridae) in Leh-Ladakh, Jammu & Kashmir, India

open access: yesJournal of Threatened Taxa, 2017
The Himalayan Marmot Marmota himalayana is one of the largest rodents of cold desert habitats, found mainly between 3,500–5,200 m above the timberline.  It is regarded as an ecosystem engineer and constitutes part of the diet of some globally endangered ...

Analysis of the SORAS domain decomposition preconditioner for non-self-adjoint or indefinite problems [PDF]

open access: yesJournal of Scientific Computing, 89, 19, 2021, 2020
We analyze the convergence of the one-level overlapping domain decomposition preconditioner SORAS (Symmetrized Optimized Restricted Additive Schwarz) applied to a generic linear system whose matrix is not necessarily symmetric/self-adjoint nor positive definite. By generalizing the theory for the Helmholtz equation developed in [I.G.

Ecological Stoichiometry of the Mountain Cryosphere

open access: yesFrontiers in Ecology and Evolution, 2019
Roughly 10% of the Earth's surface is permanently covered by glaciers and ice sheets and in mountain ecosystems, this proportion of ice cover is often even higher.

Simulations reveal climate and legacy effects underlying regional beta diversity in alpine vegetation

open access: yesFrontiers in Ecology and Evolution, 2023
IntroductionWhether the distribution and assembly of plant species are adapted to current climates or legacy effects poses a problem for their conservation during ongoing climate change.

Functional and Structural Responses of Arctic and Alpine Soil Prokaryotic and Fungal Communities Under Freeze-Thaw Cycles of Different Frequencies

open access: yesFrontiers in Microbiology, 2020
Ongoing climate change involves increasing snow scarcity, which results in more frequent freeze-thaw cycles (FTCs) in polar and alpine soils. Although repeated FTCs have been shown to alter the structure and functions of soil microbial communities, a ...

Not Too Warm, Not Too Cold: Thermal Treatments to Slightly Warmer or Colder Conditions from Mother’s Origin Can Enhance Performance of Montane Butterfly Larvae

open access: yesBiology, 2022
Climate change alters organismal performance via shifts in temperature. However, we know little about the relative fitness impacts of climate variability and how cold-adapted ectotherms mediate these effects.

Tibial Plateau Fractures among Alpine Skiers: A Retrospective Case Series

open access: yesOsteology, 2023
The purpose of this retrospective case series was to review the demographics of alpine skiers who sustain tibial plateau fractures, evaluate the inter-observer reliability of the Schatzker classification for fractures sustained while alpine skiing, and ...

A Directional Equispaced interpolation-based Fast Multipole Method for oscillatory kernels [PDF]

open access: yesarXiv, 2022
Fast Multipole Methods (FMMs) based on the oscillatory Helmholtz kernel can reduce the cost of solving N-body problems arising from Boundary Integral Equations (BIEs) in acoustic or electromagnetics. However, their cost strongly increases in the high-frequency regime.

A new look at the infrared properties of z $\sim$ 5 galaxies [PDF]

open access: yes, 2022
Recent ALMA large surveys unveiled the presence of significant dust continuum emission in star-forming galaxies at $z>4$. Unfortunately, such large programs -- i.e. ALPINE ($z\sim 5$) and REBELS ($z \sim 7$) -- only provide us with a single Far-Infrared (FIR) continuum data point for their individual targets.
