Elevation shapes alpine snow algal blooms and their influence on albedo reduction [PDF]
New Phytologist, Volume 251, Issue 5, Page 2482-2496, September 2026.Graphical summary of elevational trends in Sanguina‐dominated snow algal blooms. Increasing elevation was associated with larger cells, lower Chla content per cell, higher astaxanthin ratios, lower snow water content, and reduced cell‐normalized albedo, whereas algal cell density showed no consistent elevational trend.

The MexMAGIC population reveals the genetic architecture of traits exhibiting clinal variation in Mexican native maize [PDF]
New Phytologist, Volume 252, Issue 3, Page 1296-1313, November 2026.The MexMAGIC population mixes native maize varieties from across Mexico to study functional genetic diversity. Summary Defining the genetic basis of local adaptation is a key goal of evolutionary biology and crop improvement. Theory predicts that when selective pressures follow differences in the environment, a cline will be established.

Canalized to heat, plastic to cold: adaptive coordination of leaf and seed strategies in populations spanning an elevational gradient [PDF]
New Phytologist, Volume 250, Issue 2, Page 873-884, April 2026.Summary In tropical mountains, surviving temperature extremes demands finely tuned strategies. We investigated how populations of the bromeliad Pitcairnia flammea across a 2200 m elevational gradient balance genetic canalization and plasticity, and whether thermal strategies are coordinated between seeds and leaves.

Hyperdominant Trees Reveal Savanna Vulnerability Under Climate Change [PDF]
Global Change Biology, Volume 32, Issue 4, April 2026.The Brazilian Cerrado's forest structure relies disproportionately on just 30 hyperdominant tree species, which represent 50% of all individuals despite accounting for only 2% of species richness. This study evaluates their vulnerability under climate change scenarios for 2100.

Epiphytic Orchid Diversity along an Altitudinal Gradient in Central Nepal [PDF]
Plants, 2021 Epiphytic orchids are common in subtropical forests, but little is known about the factors that determine their diversity. We surveyed two sites (north-facing Phulchowki and south-facing Shivapuri hills), in the sub-tropical forest in the Kathmandu valley, central Nepal. Along five transects per site, spanning an altitudinal gradient of 1525–2606 m a.s.

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.

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 ...

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

Drivers of Collembola assemblages along an altitudinal gradient in northeast China [PDF]
Ecology and Evolution, 2022 Abstract Altitudinal 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.
