In the UK, grasslands comprise more than 40 % of land cover (EUROSTAT 2015). In the UK, mean laying dates for the first clutches of 20 bird species advanced on average by 8.8 days between 1971 and 1992 (Crick et al. During the past 50 years, a 7–9°F increase in midwinter temperatures on the western Antarctic Peninsula has led to a loss of sea ice. (2005) suggested that significant losses of soil organic carbon (SOC) between 1978 and 2003 must be attributed to climate change because they occurred across all types of land use. On the other hand, CH4 emission will also be reduced, while effects on DOC export are less clear. Aquat Geochem 11:241‒278, Pompe S, Hanspach J, Badeck F, Klotz S, Thuiller W, Kühn I (2008) Climate and land use change impacts on plant distributions in Germany. (2013) demonstrated that shifts in wintering areas to the northeast correlated with an increase of 3.8 °C in early winter temperature in the north-eastern part of the wintering areas, where bird abundance increased exponentially, corresponding with decreases in abundance at the south-western margin of the wintering ranges. 2008). Run-off is projected to increase in the northern part of the North Sea region and to decrease in the south (Alcamo et al. 2011; Nielsen et al. Because export of DOC and POC is controlled by many interacting factors (e.g. Overall, effects of recent climate change on terrestrial ecosystems within the North Sea region are still limited. 2002; Raymond et al. Expert Answer . 2001; Worrall et al. Declines in the duration and extent of sea ice in the Arctic leads to declines in the abundance of ice algae, which thrive in nutrient-rich pockets in the ice. Likewise, mapping of peat soils in the Dutch province of Drenthe showed that 42 % of the area of peat soils was converted to mineral soils in the last 30–40 years by carbon loss due to drainage and agricultural management; on average 1 cm peat thickness was lost per year (De Vries et al. Not logged in 1999), changes in flowering phenology (e.g. For every corn field you see, chances are good there was once a forest in its place. 2013). Due to the relatively low proportion of forests in the present land cover for countries bordering the North Sea—except Norway—the regional significance of this area as a carbon sink is relatively small or even negative compared to other European regions with higher forest cover (Janssens et al. Climatic Change 61:261‒293, Runkle BRK, Wille C, Gazovic M, Wilmking M, Kutzbach L (2014) The surface energy balance and its drivers in a boreal peatland fen of northwestern Russia. Many of these often already threatened species could therefore be particularly vulnerable to climate change. Although beech is often considered to be very sensitive to drought, several studies (Lebourgeois et al.

Many European tree species have not yet filled their potential climatic niche in Europe because of dispersal limitations (Svenning and Skov 2004; Normand et al. The latter turned out to be predominantly controlled by soil moisture. 11.8).

Changing quantities and temporal patterns of precipitation will affect the water table in peatlands; with drought lowering and increased precipitation raising peatland water levels (e.g. 2012). 2009). 2010). Forest Ecol Manage 259:698‒709, Lindsay R (2010) Peatbogs and Carbon: A critical synthesis. 2006b; Evans and Warburton 2010).

The scenarios consider two possible paths of world development: increasing globalization or increasing regionalization. Population trend is the slope of the regression of the log number of breeding pairs against year. In mires, lower water tables due to less summer precipitation and/or higher evapotranspiration will enhance NPP but also—and to a much greater degree—ecosystem respiration, leading to a net loss of peat organic matter and the release of CO2. 111cvr.k.

Dokken, K.J. [4], In some cases, ecosystem change occurs rapidly and irreversibly because a threshold, or "tipping point," is passed. As fluxes of greenhouse gases in grasslands are intimately linked to management and site conditions, grasslands can be either a sink or a source of greenhouse gases.

The magnitude of DOC fluxes in rivers correlates with organic matter storage in the soils of their catchments (e.g. A continuation of the ‘brightening period’ through reduced aerosol loading (Wild et al. 1994; Strack and Waddington 2007; Lindsay 2010). Error bars represent the standard errors of the slopes of the regression lines. Moreover, it is uncertain to what extent this potential can be realised as forests will increasingly face a climate to which the planted species or provenances are not adapted, which might increase their susceptibility to pests and pathogens, such as bark beetle (Scolytinae) outbreaks, which can lead to major forest die-back events particularly in Norway spruce Picea abies stands (Schlyter et al. 1983) and solubility, transport and toxicity of heavy metals and organic pollutants (Carter and Suffet 1982; Pokrovsky et al. Significant northward range expansions have also been documented for many typical grassland butterflies in the UK (Hill et al. 5 and Jacob et al. Not only is the decline of sea ice impairing polar bear populations by reducing the extent of their primary habitat, it is also negatively impacting them via food web effects.
