How does climate change affect regeneration of Mediterranean high‐mountain plants? An integration and synthesis of current knowledge

et al. 2017

Mediterranean mountains are extraordinarily diverse and hold a high proportion of endemic plants, but they are particularly vulnerable to climate change, and most species distribution models project drastic changes in community composition. Retrospective studies and long-term monitoring also highlight that Mediterranean highmountain plants are suffering severe range contractions. The aim of this work is to review the current knowledge of climate change impacts on the process of plant regeneration by seed in Mediterranean high-mountain plants, by combining available information from observational and experimental studies. We also discuss some processes that may provide resilience against changing environmental conditions and suggest some research priorities for the future. With some exceptions, there is still little evidence of the direct effects of climate change on pollination and reproductive success of Mediterranean high-mountain plants, and most works are observational and/or centred only in the post-dispersal stages (germination and establishment). The great majority of studies agree that the characteristic summer drought and the extreme heatwaves, which are projected to be more intense in the future, are the most limiting factors for the regeneration process. However, there is an urgent need for studies combining elevational gradient approaches with experimental manipulations of temperature and drought to confirm the magnitude and variability of species 0 responses. There is also limited knowledge about the ability of Mediterranean high-mountain plants to cope with climate change through phenotypic plasticity and local adaptation processes. This could be achieved by performing common garden and reciprocal translocation experiments with species differing in life history traits.

Italy represents a good model region for assessing vegetation responses to changing\ud climate across a broad climatic range, from Mediterranean warm-dry climate to alpine coldhumid\ud climate. We reviewed results of studies analysing the response of natural vegetation to climate\ud change in Italy, published until July 2016 in peer-reviewed journals. Evidence provided by\ud these studies shows that climate warming is expected overall to enhance plant growth in Italy, but\ud the magnitude of growth stimulation will probably vary among climatic zones, with stronger\ud effects in the cold regions of the alpine climatic zone. Drought, induced by reduced precipitation\ud and/or increased evapotranspiration, can override the positive effects of higher temperatures on\ud plant growth, not only in the Mediterranean warm-dry climatic zone but also in the less dry sub-\ud Mediterranean climatic zone and even in the temperate one. Our review highlighted 2 major\ud research gaps to which future research should be directed. First, there is poor knowledge of how\ud species composition will change in response to changing climate and how this will affect ecosystem\ud functioning in Mediterranean to temperate ecosystems. Second, there is poor knowledge of\ud possible interactions between climate-induced vegetation changes and dynamic processes related\ud to land-use changes

The study of climate-driven effects on seed traits such as germination has gained momentum over the past decade as the impact of global warming becomes more apparent on the health and survival of plant diversity.• The capacity of this suite of species to cope with warmer temperatures during a critical early life stage shows a degree of adaptation to heterogeneous environments. Predicting the effects of global change on terrestrial plant communities is crucial to managing and conserving plant diversity.
