Explaining global increases in water use efficiency: why have we overestimated responses to rising atmospheric CO(2) in natural forest ecosystems? [PDF]

open access: yes, 2013
BackgroundThe analysis of tree-ring carbon isotope composition (δ(13)C) has been widely used to estimate spatio-temporal variations in intrinsic water use efficiency (iWUE) of tree species.

Soil bacterial community changes along elevation gradients in karst graben basin of Yunnan-Kweichow Plateau

open access: yesFrontiers in Microbiology, 2022
Elevation gradients could provide natural experiments to examine geomorphological influences on biota ecology and evolution, however little is known about microbial community structures with soil depths along altitudinal gradients in karst graben basin ...

Taxonomic diversity of Passifloraceae sensu stricto along altitudinal gradient and on Serra dos Órgãos mountain slopes in southeastern Brazil [PDF]

open access: yesRodriguésia, 2022
Altitudinal gradients, among other abiotic factors, are directly linked to species’ diversity patterns and distributions. Another important factor to be considered is the geographic position of a mountain chain, with oceanic and continental-facing slopes

Tree growth and its climate signal along latitudinal and altitudinal gradients: comparison of tree rings between Finland and the Tibetan Plateau [PDF]

open access: yesBiogeosciences, 2017
Latitudinal and altitudinal gradients can be utilized to forecast the impact of climate change on forests. To improve the understanding of how these gradients impact forest dynamics, we tested two hypotheses: (1) the change of the tree growth–climate ...

Distribution and Assembly Processes of Soil Fungal Communities along an Altitudinal Gradient in Tibetan Plateau

open access: yesJournal of Fungi, 2021
In soil ecosystems, fungi exhibit diverse biodiversity and play an essential role in soil biogeochemical cycling. Fungal diversity and assembly processes across soil strata along altitudinal gradients are still unclear. In this study, we investigated the

Epiphytic Orchid Diversity along an Altitudinal Gradient in Central Nepal [PDF]

open access: yesPlants, 2021
Epiphytic orchids are common in subtropical forests, but little is known about the factors that determine their diversity. We surveyed two sites (north-facing Phulchowki and south-facing Shivapuri hills), in the sub-tropical forest in the Kathmandu valley, central Nepal. Along five transects per site, spanning an altitudinal gradient of 1525–2606 m a.s.

Should altitudinal gradients of temperature and precipitation inputs be inferred from key parameters in snow-hydrological models? [PDF]

open access: yesHydrology and Earth System Sciences, 2020
This paper evaluates whether snow-covered area and streamflow measurements can help assess altitudinal gradients of temperature and precipitation in data-scarce mountainous areas more efficiently than using the usual interpolation procedures.

Behavioural tuning in a tropical amphibian along an altitudinal gradient [PDF]

open access: yesBiology Letters, 2017
Males of the coqui treefrog,Eleutherodactylus coqui, produce a distinct two-note ‘co-qui' advertisement call from sunset to midnight throughout most of the year. Previous work established that both the spectrotemporal aspects of the call and the frequency of highest inner-ear sensitivity change with altitude above sea level.
