Altitudinal Variations in Coniferous Vegetation and Soil Carbon Storage in Kalam Temperate Forest, Pakistan

open access: yesPlants
Understanding the complex interplay among altitudinal gradients, tree species diversity, structural attributes, and soil carbon (C) is critical for effective coniferous forest management and climate change mitigation. This study addresses a knowledge gap

Butterfly distribution along altitudinal gradients: temporal changes over a short time period

open access: yesNatureza & Conservação, 2019
Mountain ecosystems are particularly sensitive to changes in climate and land cover, but at the same time, they can offer important refuges for species on the opposite of the more altered lowlands.

Ecophysiological Plasticity and Cold Stress Adaptation in Himalayan Alpine Herbs: Bistorta affinis and Sibbaldia procumbens

open access: yesPlants, 2019
Plants have evolved several metabolic pathways as a response to environmental stressors such as low temperatures. In this perspective, it is paramount to highlight physiological mechanisms of plant responses to altitudinal gradients as a proxy to ...

Properties of thick discs formed in clumpy galaxies [PDF]

open access: yes, 2014
We examine a possible formation scenario of galactic thick discs with numerical simulations. Thick discs have previously been argued to form in clumpy disc phase in the high-redshift Universe, which host giant clumps ...

Widespread phenotypic and genetic divergence along altitudinal gradients in animals [PDF]

open access: yesJournal of Evolutionary Biology, 2013
AbstractAltitudinal gradients offer valuable study systems to investigate how adaptive genetic diversity is distributed within and between natural populations and which factors promote or prevent adaptive differentiation. The environmental clines along altitudinal gradients tend to be steep relative to the dispersal distance of many organisms ...

Unravelling genetics at the top: mountain islands or isolated belts? [PDF]

open access: yes, 2017
Background and Aims In mountain plant populations, local adaptation has been described as one of the main responses to climate warming, allowing plants to persist under stressful conditions.

Impact of the Altitudinal Gradients of Precipitation on the Radar QPE Bias in the French Alps

open access: yesAtmosphere, 2019
In the French Alps the quality of the radar Quantitative Precipitation Estimation (QPE) is limited by the topography and the vertical structure of precipitation. A previous study realized in all the French Alps, has shown a general bias between values of

Macrofungi of the altitudinal gradient, Northern Rocky Mountains [PDF]

open access: yes, 2021
Macrofungal communities of four altitudinal zones of the Northern Rocky Mountain region are described and compared with respect to species richness, production (g/100m2/yr), functional structure (mycorrhizal vs. decomposer), seasonality of activity and relationship to temperature and rainfall.

Beyond Earth: Resilience of Quasi‐2D Perovskite Solar Cells in Space

open access: yesAdvanced Materials, EarlyView.
In the article (DOI: 10.1002/adma.202520433), Christoph Putz and co‐workers demonstrate rigid quasi‐2D perovskite solar cells operating in low Earth orbit, delivering stable power for more than 100 days under real‐space conditions. In‐orbit performance is correlated with extensive ground‐based thermal and proton‐irradiation studies on rigid and ...

Vegetation Dynamics in Ecuador [PDF]

open access: yes, 2019
Global forest cover has suffered a dramatic reduction during recent decades, especially in tropical regions, which is mainly due to human activities caused by enhanced population pressures.
