Document Summary
Cc effects ecosystem productivity, helps spread of invasive species, changing specie interactions with each other and their environment. Impacts to primary production have significant effects throughout entire ecosystem. Uncertain projections due to co2 effects on terrestrial ecosystem dynamics, potential effects of nutrient limitation, impacts of fire, insect outbreaks, incomplete understanding of the impacts of changing climate extremes. Primary production in oceans also expected to modest to moderate declines for most low to mid latitude oceans over next century. Primary production increasing in arctic due to less ice cover. Small changes in marine primary productivity are likely to result in even larger changes to the biomass of fisheries catch. Effects of altered species interactions and resource mismatch. Decrease in fitness, disrupt persistence and resilience of populations, alter ecosystems and ecosystem services, and increase the risk of localized extinctions. Changes in what they look like changes the food web. Resource mismatch potential with migrating animals - advancing vegetation.
