Climate Change Affect Plants Essay Example for Free
Climate Change Affect Plants tasteHistorical climate change has had a profound effect on current biogeography, so we batch expect our ongoing and rapid climate change, to have as great an effect. Climate change has big implications for nearly every aspect of life on Earth, and effects atomic number 18 already being felt. * Temperatureeffectsaverage, token(prenominal) or maximum can be important determinants of plant distribution For framework the Palmae/ palm family are cold intolerant as their single meristem is susceptible to frost.Conversely, boundaries between vegetation types (e. g. Arctic treeline) are generally determined by summer warmth * Rainfall is also an important determinant for example it affects the balance of grasses to woody vegetation * Other factors such as soil type or herbivory may also be affected by climate change. Effects on Plant Diversity * Species left behind as they are unable to change distribution fast enough. Species with long life cycles and/ or slow dispersal are curiously vulnerable. Some isolated or disjunct species are particularly vulnerable, as they may have nowhere to go. These include Arctic and alpine species, and Island endemics Coastal species which will be squeezed between gracious settlements and rising sea levels.* Plant genetic composition may change in response to the selection pressure of climate change. * Some plant communities or species associations may be woolly-headed as species move and adapt at different rates. Increased invasions by alien species may occur, as conditions become more suitable for exotic species whilst native species become less well suited to their surroundings (for example, Bromus is more invasive in wet years (Smith et al, 2000)). This is especially true given human interventions which have deliberately and accidentally facilitated the spread of species across the globe. * Many plant communities act as sinks (store carbon), which helps to starting carbon emissions. However, over the next 70 years, the effects of climate change on plants mean more terrestrial sinks may become sources.
