Altitudinal migration behavior patterns of birds on the eastern slope of Mt. Gongga, China
Avian Research, 2023 Many bird species in montane regions exhibit altitudinal migration behavior; however, altitudinal migration of birds is still understudied, especially in Asia. Mt. Gongga (7556 m) is the highest peak of the Hengduan Mountains in Southwest China.

Behavioural tuning in a tropical amphibian along an altitudinal gradient [PDF]
Biology 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.

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.

Community structure of macromoths along altitudinal gradients in Korea
Journal of Asia-Pacific Biodiversity, 2021 This study was aimed to (1) document the macromoth species richness and diversity along altitudinal gradients, (2) investigate the community structure along altitudinal gradients, and (3) analyze the similarity within each altitude using nonmetric ...

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.

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.

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 ...

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

Variations of leaf traits of an alpine shrub Sieversia pentapetala along an altitudinal gradient and under a simulated environmental change [PDF]
, 2001 P(論文)We investigated intraspecific variations of leaf traits such as number of leaves, leaf size, leaf mass per shoot, leaf mass per area (LMA) and leaf nitrogen concentration (leaf N), in a deciduous alpine dwarf shrub Sieversia pentapetala (L.) Greene (
