Altitudinal gradients, plant hybrid zones and evolutionary novelty [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2014 Altitudinal gradients are characterized by steep changes of the physical and biotic environment that present challenges to plant adaptation throughout large parts of the world. Hybrid zones may form where related species inhabit different neighbouring altitudes and can facilitate interspecific gene flow and potentially the ...

Drought sensitivity of Norway spruce is higher than that of silver fir along an altitudinal gradient in southwestern Germany [PDF]
, 2013 For Central Europe, climate projections foresee an increase in temperature combined with decreasing summer precipitation, resulting in drier conditions during the growing season.

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

Life-History Responses to the Altitudinal Gradient [PDF]
, 2017 We review life-history variation along elevation in animals and plants and illustrate its drivers, mechanisms and constraints. Elevation shapes life histories into suites of correlated traits that are often remarkably convergent among organisms facing the same environmental challenges.

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.

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