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.

Functional responses in a lizard along a 3.5‐km altitudinal gradient

open access: yesJournal of Biogeography, 2023
AbstractAimPhysiological and metabolic performance are key mediators of the functional response of species to environmental change. Few environments offer such a multifaceted array of stressors as high‐altitude habitats, which differ markedly in temperature, water availability, UV radiation and oxygen pressure compared to low‐altitude habitats. Species

Elevational and latitudinal changes in tree associations and diversity in the Eastern Arc mountains of Tanzania [PDF]

open access: yes, 1996
A total of 200 variable-area plots covering 20 3 ha containing 4000 trees with a basal area of 921 4 m2 were assessed over a combined elevational range of 410-2180 m in the moist forests of three Tanzanian Eastern Arc mountains: West Usambara, Nguru and ...

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 ...

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.

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.

Methane-cycling microorganisms in soils of a high-alpine altitudinal gradient [PDF]

open access: yesFEMS Microbiology Ecology, 2016
Methanogens and methanotrophs play unique roles as producers and consumers of the greenhouse gas methane (CH4) in soils, respectively. Here, we aimed to reveal whether and to which extent methane-cyclers occur in high-alpine soils, and to assess their spatial distribution along an altitudinal gradient (2700-3500 m) in the Austrian Alps at sites located

Integrating the effects of latitude and altitude on the spatial differentiation of plant community diversity in a mountainous ecosystem in China.

open access: yesPLoS ONE, 2017
Varying patterns of plant community diversity along geographical gradients are a significant topic in biodiversity research. Here, to explore the integrated effects of latitude and altitude on the plant community diversity in a mountainous ecosystem, we ...

Freezing tolerance in grasses along an altitudinal gradient in the Venezuelan Andes [PDF]

open access: yesOecologia, 2006
The tropical high Andes experience greater daily temperature oscillations compared to seasonal ones as well as a high frequency of night frost occurrence year round. Survival of organisms, under such environmental conditions, has been determined by selective forces which have evolved into adaptations including avoidance or tolerance to freezing.

Höhengradienten in der Biodiversitäts-Forschung: eine Übersicht unter Berücksichtigung des Klimawandels [PDF]

open access: yes, 2013
Mountains, with their isolated position and altitudinal belts, are hotspots of biodiversity. Their flora and fauna have been observed worldwide since the days of Alexander von Humboldt, which has led to basic knowledge and understanding of species ...
