Evaluation of altitudinal distribution and population dynamics of introduced Brown trout (Salmo trutta) and native Snow trout (Schizothorax richardsonii) in river Asiganga, Uttarakhand (India)

open access: yesEnvironment Conservation Journal, 2016
Mountains of Himalaya, with unique topology and geographical regions, are hotspots of biodiversity. Their flora and fauna have been investigated for abundance in species composition and interactions.

Variation in woody leaf anatomical traits along the altitudinal gradient in Taibai Mountain, China

open access: yesGlobal Ecology and Conservation, 2021
As important indicators of leaf traits, leaf anatomical traits are sensitive and adaptable to environmental changes. However, how leaf anatomical traits at species and community levels vary along the altitudinal gradients is still unclear. In this study,

Local adaptation with high gene flow: temperature parameters drive adaptation to altitude in the common frog (Rana temporaria) [PDF]

open access: yes, 2014
Both environmental and genetic influences can result in phenotypic variation. Quantifying the relative contributions of local adaptation and phenotypic plasticity to phenotypes is key to understanding the effect of environmental variation on populations.

Differential effects of soil chemistry on the foliar resorption of nitrogen and phosphorus across altitudinal gradients

open access: yesFunctional Ecology, 2019
Nutrient resorption from senescing leaves prior to litterfall is a strategy for nutrient conservation in vascular plants. However, the mechanisms through which soil fertility and/or foliar nutrient status affect nutrient resorption are not yet fully ...

Altitudinal Patterns of Species Diversity and Phylogenetic Diversity across Temperate Mountain Forests of Northern China. [PDF]

open access: yesPLoS ONE, 2016
The spatial patterns of biodiversity and their underlying mechanisms have been an active area of research for a long time. In this study, a total of 63 samples (20m × 30m) were systematically established along elevation gradients on Mount Tai and Mount ...

Parallel functional and stoichiometric trait shifts in South American and African forest communities with elevation [PDF]

open access: yes, 2017
The Amazon and Congo basins are the two largest continuous blocks of tropical forest with a central role for global biogeochemical cycles and ecology. However, both biomes differ in structure and species richness and composition.

Spatial trends of Potamogetonaceae along an altitudinal gradient

open access: yesBiologia, 2020
Studying the effect of altitude on species distribution may help us to predict the response of species to future climate changes, which will likely cause upward migration of vegetation zones. In this study, we aimed to analyze distribution and abundance patterns of Potamogetonaceae along an altitudinal gradient and to determine the species ...

Understory epiphytic pteridophytes along altitudinal gradients on opposite slopes in the Atlantic Forest

open access: yesRodriguésia, 2023
Gradual climatic changes caused by mountains’ altitudinal variation promote alterations in the structure of ecological communities. Environmental changes are also expected according to the slope’s position in relation to the sea.

Altitudinal Gradient of Evapotranspiration in Tropical Highlands

open access: yes, 2022
Tropical highlands supply water for large cities in the Andes. Based on meteorological records from three weather stations in the paramo Chingaza, Colombia evapotranspiration (ET) is estimated based on the Penman-Monteith (P-M) approach to compare the altitudinal variation and assess the radiation and aerodynamic effects on the water losses.

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.
