Strong altitudinal partitioning in the distributions of ectomycorrhizal fungi along a short (300 m) elevation gradient [PDF]

open access: yes, 2015
• Changes in species richness and distributions of ectomycorrhizal (ECM) fungal communities along altitudinal gradients have been attributed to changes in both host distributions and abiotic variables.

Biotic rather than abiotic factors influence ground-dwelling mygalomorph spider assemblages along an altitudinal gradient in the Brazilian semi-arid domain [PDF]

open access: yesPapéis Avulsos de Zoologia
The species richness of organisms associated with altitudinal gradients tends to decline with increasing altitude, however, this pattern is not observed in mygalomorph.

Evaluating the efficacy of visual encounter and automated acoustic survey methods in anuran assemblages of the Yungas Andean forests of Argentina

open access: yesEcological Indicators, 2021
Identifying adequate methods and tools for biodiversity monitoring is fundamental in ecology and conservation biology. Most of the standardised monitoring techniques involve the presence of the researchers at the survey sites meanwhile, passive acoustic ...

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

Carbon stock potential of scattered trees on farmland along an altitudinal gradient in Tigray, Northern Ethiopia

open access: yesEcological Processes, 2018
Introduction Trees on agricultural landscape play a vital role in ecosystem services including food security that supports human livelihood. They can further offer synergy between adaptation and mitigation in addressing climate change impact ...

Interpopulation Plasticity in a Darkling Beetle Life-History along a Whole Oceanic Island Altitudinal Gradient

open access: yesInsects, 2021
Insects show remarkable phenotypic plasticity in response to changing environmental conditions. The abiotic factors that determine their phenotypes often vary in time and space, and oceanic islands harbour ideal environments for testing predictions on ...

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

Scientific results of the Bryotrop expedition to Zaire and Rwanda : 7., life strategies of epiphytic bryophytes from tropical lowland and montane forests, ericaceous woodlands and the Dendrosenecio subpáramo of the eastern Congo basin and the adjacent mountains (Parc National de Kahuzi-Biega/Zaire, Forêt de Nyungwe/Rwanda) [PDF]

open access: yes, 1995
Life strategies of epiphytic bryophytes are studied along an altitudinal gradient from the eastern Congo basin (tropical lowland zone) to the mountains of the East-African graben (tropical subalpine/alpine Zone; BRYOTROP III-transect).
