Temporal and spatial variation in active layer depth in the McMurdo Sound Region, Antarctica [PDF]

open access: yes, 2010
A soil climate monitoring network, consisting of seven automated weather stations, was established between 1999 and 2003, ranging from Minna Bluff to Granite Harbour and from near sea level to about 1700m on the edge of the polar plateau.

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 ...

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 ...

Bioindicators for Assessing Soil Quality in Ecuador’s Jun Jun Micro-Watershed

open access: yesAgronomy
The evaluation of soil quality in different altitudinal gradients, with vegetative and non-vegetative subareas, is crucial for proper soil functioning and optimal crop growth, thus contributing to the sustainability of agroecosystems.

Orchid diversity along an altitudinal gradient in the central Balkans

open access: yesFrontiers in Ecology and Evolution, 2022
Understanding patterns of species diversity along an altitudinal gradient is the major topic of much biogeographical and ecological research. The aim of this study was to explore how richness and density of orchid species and subspecies in terms of different categories of underground organ systems and pollination systems vary along an altitudinal ...

The physiology and biomechanics of avian flight at high altitude [PDF]

open access: yes, 2006
Many birds fly at high altitude, either during long-distance flights or by virtue of residence in high-elevation habitats. Among the many environmental features that vary systematically with altitude, five have significant consequences for avian flight ...

Dynamics of aboveground vegetation biomass and carbon stocks along the altitudinal gradients and overstorey composition types in the temperate Himalayan region

open access: yesTrees, Forests and People
Forests, covering approximately thirty percent of the Earth's total surface area, are the world's largest carbon sink and a crucial player in mitigating climate change through carbon sequestration.
