CC affect on terrestrial ecosystems (flora and fauna)

change in geographical distribution

• increase in air temperature = change in geographical distribution of terrestrial spaces

• tropical species migrate toward higher latitude and altitude with lower temperature

change in composition

• species distribution + population density of prey and predator and competitors change and mix = food webs disrupted = new terrestrial communities

• less terrestrial species if habitat becomes unsuitable (migrate)

• mountain top warmer = mountain species that like cold reduce = competition sigh specifies at lower altitudes = high extinction rate

• plants cannot move and adapt fast enough = decline

impacts on droughts

• plant cannot move to find water = vulnerable to disease and insect attack = wither and die

• tree decline = habitat and food = decrease = species unable to adapt and go extinct

• force species move to new places for water food and habitat = increase spread of diseases that thrive in warm atmosphere (botulism and cholera)

impact of excessive rainfall

• flood = loss of habitat = terrestrial species drown = extinct
