Climate change impacts on biodiversity at large — with particular reference to ALARM results Impacts of climate change on plants A changing climate modifies the conditions which shape the physiological behaviour, the productivity and the ranges of many plants and thus, is expected to induce manifold reactions of climate sensitive species and ecosystems e.
While a European scale analysis yielded strong impacts especially on Mediterranean and high mountain plant species Thuiller et al. Using this data and assigning the species to Climate change impacts on biodiversity: The species assigned to forb communities, forest grassland ecotones and tall herb slopes outside floodplains, plant cultures, and urban, commercial, and industrial areas were least negatively impacted by climate change.
On the basis of long-term phenological records, trends in the response of living organisms to climatic changes can be tracked.
Evidence that events in spring have been happening earlier in recent decades arises from a wide range of species and across a wide range of geographic locations. Despite some inconsistencies in the numeric values of the data, an overall trend of 2.
Fewer phenological data are available for the fall season.
However, the few data sets that include phenophases in both spring and autumn reveal a trend towards a prolongation at both ends of the season and thus, an extension of the growing season Walther The observed lengthening of the growing season is based on terrestrial phenological data records with satellite observations of leaf area index anomalies over the past two decades e.
In addition to phenological changes, climate warming is also expected to shift the margins of species ranges or boundaries of biomes e. Evidence for species range shifts has been reported from various habitats Walther et al.
The period of milder winter conditions since the s for example is in temporal synchrony with a major phase of spread and establishment of thermophilous evergreen broad-leaved species on sites with former deciduous forest vegetation south of the Alps Walther et al.
In analogy, the partial replacement of neighbouring altitudinal belts is reported by Penuelas and Boada from north-eastern Spain. This upward shift of vegetation belts is ascribed to the rising annual temperature of 1.
In the Arctic, Cornelissen et al.
An analogue process of increasing species number and frequency is found at the altitudinal margin of plant life. In the Alps, e.
Hofer and Grabherr et al. A recent update of the flora of high mountain peaks in the Swiss Alps based on the Hofer revealed that the trend of increasing species numbers in the summit areas continues and might even have been accelerated in the last decade Walther et al.
The biotic response to thirty years of enhanced global warming has become perceptible and substantial. An overwhelming number of studies provide evidence for climate change impacts on species, communities and ecosystems HughesMcCartyWalther et al.
In the long-term perspective, the biotic implications of climate change and its evolutionary consequences depend on both the magnitude and rate of global warming as well as on the development of other human influences on biological systems such as habitat conversion, overexploitation and pollution e.Publikation: Volkshochschule Aachen (Hrsg.)
