The major response of organisms to the climatic oscillations of the Quaternary was migration. Considering alpine plants, migration into low elevation cold-stage refugia took place in glacial periods, and re-migration into high elevation areas in interglacial periods and the Holocene. The present review examines the possibility that populations at the rear edge of re-migrating species persisted and

Climate change, such as warming, is a threat to mountain ecosystems in the forest-line ecotone. This influence could seriously affect bryophytes, because they easily lose their internal water at high temperatures. We conducted experimental warming using open-top chambers (OTCs) in a forest-line ecotone in central Japan and examined its influence on bryophyte cover. Six years after the experiment was

In alpine plants, the temporal variation in the concentrations of non-structural carbohydrates (NSC) is closely related to the growth phenology, which is largely controlled by annual variations in temperature. However, in alpine areas of Mediterranean-type climate regions, plants growing at low elevations are also exposed to seasonal drought. Given the influence of drought on growth phenology and gas

Intraspecific genetic consequences of Pleistocene climate change on Lupinus microphyllus (Fabaceae) in the Andes Alp. Botany (IF 2.7) Pub Date : 2022-01-28 Diana L. A. Vásquez, Michael Møller Hansen, Henrik Balslev, Roswitha Schmickl
The role of Pleistocene climate change in shaping patterns of genetic and species diversity has been widely demonstrated. However, tropical mountains remain less explored. In the northern Andes, distributional shifts of the vegetation during the Pleistocene are believed to have promoted plant diversification. In this regard, the role of gene flow and geographic isolation has been intensively debated

Studies in alpine environments indicate that nurse plants can facilitate other species mainly through direct mechanisms (i.e., improvements in local abiotic conditions). However, far fewer studies consider indirect facilitation, including the effect on plant–plant interactions of symbiosis with soil fungi. We asked whether the nurse shrub Hypericum laricifolium affected the colonization and activity

Uncertainty still exists on the directions and intensity of changes in leaf herbivory under scenarios of global warming. We, therefore, conducted an investigation on insect herbivory along an elevational gradient to explore how leaf herbivory may respond to future climate warming using a space-for-time substitution approach. We hypothesize that the leaf herbivory for alpine woody species should decline

Bacterial communities in the phyllosphere are shaped by host genotype and phenotype and spatio-temporal variation of the environment. In turn, bacteria have the potential for altering the plant phenotype. Field experiments can help to estimate bacterial effects on plant functional traits under natural conditions. We used a transplantation approach of culturable bacterial communities to explore how

Páramo, the most species-rich tropical mountain ecosystem, is relatively well-researched in terms of the diversity and evolutionary sources of its flora, yet we know very little about the diversification within this environment.

Climatic changes threaten the diverse and highly endemic páramo flora of the equatorial Andes with species loss and reduction of plant community diversity.

Alpine plant radiations are common across all major mountain systems of the world, and have been regarded as the main explanation for the species diversity found within these areas. To study the mechanisms behind the origin of this diversity, it is necessary to determine phylogenetic relationships and species boundaries in radiating alpine groups. The genus Dendrosenecio (Asteraceae) is an iconic example

Mountains are reservoirs for a tremendous biodiversity which was fostered by a suite of factors acting in concert throughout evolutionary times.

Here, we investigate these factors as correlates of diversification of three closely related sections of Gentiana in the European

Seed germination and seedling recruitment are key processes in the life cycle of plants. They enable populations to grow, migrate, or persist. Both processes are under environmental control and influenced by site conditions and plant–plant interactions. Here, we present the results of a seed-sowing experiment performed along an elevation gradient (2000–2900 m a.s.l.) in the European eastern Alps. We

Pollinator sharing among co-flowering plants mediates patterns of pollen transfer Alp. Botany (IF 2.7) Pub Date : 2021-04-23 Tao Zhang, Xiaoxin Tang, Qiang Fang
Co-flowering plant species often share pollinators, which could result in interspecific pollination. Despite some evidence suggesting plant species with overlapping pollinators influence each other’s pollination, the relationship between pollinator sharing and heterospecific pollen transfer (HPT) is not well explained at the community level. Here, we sampled a plant-pollinator visitation network to

Flowering phenology in alpine grassland strongly responds to shifts in snowmelt but weakly to summer drought Alp. Botany (IF 2.7) Pub Date : 2021-04-05 Maria Vorkauf, Ansgar Kahmen, Christian Körner, Erika Hiltbrunner
Alpine plants complete their seasonal phenological cycle during two to three snow-free months. Under climate change, snowmelt advances and the risk of summer droughts increases. Yet, photoperiodism may prevent alpine plants from benefiting from an earlier start of the growing season. To identify the drivers of flowering phenology in the seven main species of an alpine grassland, we experimentally shifted

Habitat-specific effects of flowering advance on fruit-set success of alpine plants: a long-term record of flowering phenology and fruit-set success of Rhododendron aureum Alp. Botany (IF 2.7) Pub Date : 2021-03-14 Gaku Kudo
Global warming tends to accelerate flowering phenology of alpine plants, and it may cause a decrease in fruit production due to lower pollinator activity and/or higher risk of frost damage earlier in the season. Because flowering period of alpine plants varies highly depending on snowmelt conditions, the effects of phenological variation on fruit-set success may vary among local populations. I observed

While climatic research about treeline has a long history, the climatic conditions corresponding to the upper limit of closed alpine grasslands remain poorly understood.

Global warming may pose a serious threat to seed germination and establishment in alpine ecosystems, given that temperature is a primary factor in stimulating seed germination and regulating changes in seed dormancy. However, to date, little is known about the relative importance of temperatures experienced by parents versus by the seeds (after dispersal). In this study, we tested the effects of warming
