From: Impact of climate change on biodiversity and food security: a global perspective—a review article
Factors | Impacts on biodiversity | Sources |
---|---|---|
Habitat loss and fragmentation | Decrease in natural habitat, homogenization of species composition, fragmentation of landscapes, and soil degradation | |
Invasive alien species | Competition with and predation on native species Changes in ecosystem function Extinctions and Homogenization | |
Overexploitation | Genetic contamination Extinctions and decreased populations Alien species introduced after resource depletion | |
Climate change | Homogenization and changes in ecosystem functioning Extinctions Expansion or contraction of species ranges | |
Pollution | Changes in species compositions and interactions Higher mortality rates Nutrient loading and acidification | |
Anthropogenic threats | species extinction Habitat loss and conversion Degradation and fragmentation Over Harvesting |
