Alpine plants prosper in treeless vegetation above the high elevation climatic treeline through their small stature, apt seasonal development, and 'managing' of the microclimate. Despite the wide range of thermal niches provided by the alpine environment, certain habitat types may shrink with climate warming, posing challenges for some plant species.
The alpine belt hosts the treeless vegetation above the high elevation climatic treeline. The way alpine plants manage to thrive in a climate that prevents tree growth is through small stature, apt seasonal development, and 'managing' the microclimate near the ground surface. Nested in a mosaic of micro-environmental conditions, these plants are in a unique position by a close-by neighborhood of strongly diverging microhabitats. The range of adjacent thermal niches that the alpine environment provides is exceeding the worst climate warming scenarios. The provided mountains are high and large enough, these are conditions that cause alpine plant species diversity to be robust against climatic change. However, the areal extent of certain habitat types will shrink as isotherms move upslope, with the potential areal loss by the advance of the treeline by far outranging the gain in new land by glacier retreat globally.

Summary: Increasing atmospheric carbon dioxide concentration has the potential to enhance plant growth and contribute to a global terrestrial carbon sink, slowing down the rate of climate change. However, the complexity of ecosystem responses and interactions with other global change factors make it challenging to determine the exact impact of CO2 on the climate.

Flowering phenology in alpine grassland strongly responds to shifts in snowmelt but weakly to summer drought

Maria Vorkauf, Ansgar Kahmen, Christian Korner, Erika Hiltbrunner

Summary: The study found that flowering phenology of alpine plants is mainly influenced by snowmelt dates and photoperiod under climate change. The plants in alpine grasslands can be divided into two types, one primarily tracking snowmelt dates, and the other mainly controlled by photoperiod. Photoperiod affects flowering time by modulating temperature sums at flowering.

Mountain definitions and their consequences

Summary: This communication explains the differences among various popular mountain definitions, which are crucial for global assessments of plant species richness and their responses to climatic change, as well as for assessing human population density in and around mountainous regions.

Warming does not delay the start of autumnal leaf coloration but slows its progress rate

Nan Jiang, Miaogen Shen, Philippe Ciais, Matteo Campioli, Josep Penuelas, Christian Korner, Ruyin Cao, Shilong Piao, Licong Liu, Shiping Wang, Eryuan Liang, Nicolas Delpierre, Kamel Soudani, Yuhan Rao, Leonardo Montagnani, Lukas Hortnagl, Eugenie Paul-Limoges, Ranga Myneni, Georg Wohlfahrt, Yongshuo Fu, Ladislav Sigut, Andrej Varlagin, Jin Chen, Yanhong Tang, Wenwu Zhao

Summary: This study investigates the response of the timing of leaf coloration to temperature and finds that the onset of leaf coloration is not sensitive to climate warming, while the rate of progress of leaf coloration is more sensitive to temperature, resulting in an extension of the duration of leaf senescence under warming. It also provides observational evidence of photoperiod control of autumnal leaf senescence at biome and continental scales.

Four ways to define the growing season

Christian Korner, Patrick Mohl, Erika Hiltbrunner

Summary: The concept of growing season in terrestrial ecosystems, which determines plant biomass production, lacks a well-defined definition. This study shows different aspects of growing season, including the actual growth period of plants, the period defined by phenological markers, the period of vegetation achieving net primary production, and the potential growth period based on meteorological criteria. The duration of this "window of opportunity" is a strong predictor for global net primary production, especially in forests. These different definitions have important implications for understanding and modeling plant growth and biomass production, challenging the common view that phenology is a proxy for productivity variation.

Not every high-latitude or high-elevation forest edge is a treeline

Christian Korner, Gunter Hoch

Summary: This perspective article addresses the recent interest in treeline studies as a result of attempts to identify climate warming effects on mountain and arctic vegetation. The article emphasizes the importance of clear-cut definitions, consistent terminology, and a theoretical framework for hypothesis testing. By applying the ecological niche concept, the potential and realized niche edges can be used to define the climatic limit and deviations of tree growth at treeline. Additionally, it is explained why other abiotic factors, such as microclimate and moisture, do not diminish the classical isotherm concept.

Chronic in situ tissue cooling does not reduce lignification at the Swiss treeline but enhances the risk of 'blue' frost rings

Christian Korner, Armando Lenz, Günter Hoch

Summary: In a 2013 paper, Lenz et al. investigated the effects of chronic warming or cooling on trees growing at the low-temperature limit. They found that a 3 K cooling did not impact lignification at treeline, but when a frost event occurred during early ring formation, the cooling resulted in a non-lignified layer of cells followed by normally lignified cells. This suggests that chronic cooling does not affect lignification but increases the risk of frost damage in premature xylem tissue.

Weather modifies the spatial extent of carbohydrate transfers from CO2-supplied broad-leaved trees to ectomycorrhizal fungi

Erik A. Hobbie, Rolf Siegwolf, Christian Koerner, Katharina Steinmann, Markus Wilhelm, Matthias Saurer, Sonja G. Keel

Summary: In a Swiss forest, the spatial and temporal dynamics of carbon transfer from tree hosts to ectomycorrhizal fungi were studied. The results showed that fungal morphology did not affect carbon transfer, and carbohydrates were the primary form of carbon transferred to sporocarps across different zones. Environmental factors such as solar radiation and drought influenced carbon transfer.

Concepts in Alpine Plant Ecology

Christian Korner

Summary: The alpine life zone is a unique biome where mountains are high enough to host small stature plants with varying morphology, anatomy, and physiology. This article summarizes several principles that govern life in this cold and hostile environment, including the role of aerodynamic decoupling, the concepts of limitation and stress in an evolutionary context, and the importance of developmental flexibility and functional diversity.

Soil invertebrate abundance, diversity, and community composition across steep high elevation snowmelt gradients in the European Alps

Julia Seeber, Christian Newesely, Michael Steinwandter, Alexander Rief, Christian Koerner, Ulrike Tappeiner, Erwin Meyer

Summary: This study focused on the abundance, diversity, and composition of soil invertebrates along snowmelt gradients in the European Alps. Soil conditions and time of snowmelt were not correlated with densities of soil animals, indicating that variations in soil organic matter and sand content had little effect on soil invertebrates in snowbed habitats. Invertebrate species assemblages in snowbeds along the west-east transect of the European Alps were found to be rather similar.
