Contrasting altitudinal variation of alpine plant communities along the Swedish mountains

Ecology and Evolution, 2020
Changes in abiotic factors along altitudinal and latitudinal gradients cause powerful environmental gradients. The topography of alpine areas generates environmental gradients over short distances, and alpine areas are expected to experience greater ...

Tree diversity and biomass carbon stock analysis along altitudinal gradients in coffee-based agroforestry system of Western Ethiopia

Cogent Food & Agriculture, 2022
Agroforestry systems are thought to reconcile biodiversity protection with food production and as a means of climate change adaptation and mitigation options. The contribution of a coffee-based agroforestry system to tree diversity and carbon stock along

The distribution of mosquitoes across an altitudinal gradient in the Galapagos Islands [PDF]

Journal of Vector Ecology, 2017
An avian malaria parasite (genus Plasmodium) has been detected consistently in the Galapagos Penguin (Spheniscus mendiculus) and less frequently in some passerines. We sampled three resident mosquito species (Aedes taeniorhynchus, Culex quinquefasciatus, and Aedes aegypti) using CDC light and gravid traps on three islands in 2012, 2013, and 2014.

Grassland biomass dynamics along an altitudinal gradient in the Pampa [PDF]

Journal of Range Management, 2000
Above and below-ground biomass and necromass dynamics were assessed for 3 grassland sites located at 550, 850, and 1,025 m elevation in Sierra de la Ventana range (38 degrees 1'S 62 degrees 2'W) in Argentina. The objective was to determine if differences existed in dry matter structure, mycorrhizae infection, net primary productivity (NPP) partitioning

The effect of elevation on species richness in tropical forests depends on the considered lifeform: results from an East African mountain forest [PDF]

, 2019
Elevation gradients in tropical forests have been studied but the analysis of patterns displayed by species richness and elevation have received little attention.

Lauraceae Along an Altitudinal Gradient in Southern Brazil [PDF]

Floresta e Ambiente, 2019
ABSTRACT We performed a phytosociological study on an altitudinal gradient in Lauráceas State Park (Parque Estadual das Lauráceas/PR), aiming to describe the Montane Atlantic Rain Forest, to verify the importance of Lauraceae, and to evaluate the communities’ successional stage.

Drivers of Collembola assemblages along an altitudinal gradient in northeast China [PDF]

Ecology and Evolution, 2022
AbstractAltitudinal changes in the diversity of plants and animals have been well documented; however, soil animals received little attention in this context and it is unclear whether their diversity follows general altitudinal distribution patterns. Changbai Mountain is one of few well‐conserved mountain regions comprising natural ecosystems on the ...

Parallel divergent adaptation along replicated altitudinal gradients in Alpine trout

BMC Evolutionary Biology, 2012
Background The European trout (Salmo trutta species complex) occurs across a very wide altitudinal range from lowland rivers to alpine streams. Historically, the major European river systems contained different, evolutionarily distinct trout lineages ...

Lake productivity and waterbird functional diversity across geographic and environmental gradients in temperate China

Ecology and Evolution, 2020
Geographical gradients in species diversity have long fascinated biogeographers and ecologists. However, the extent and generality of the effects of the important factors governing functional diversity (FD) patterns are still debated, especially for the ...
