Anthropogenic Impacts on Terrestrial Ecosystems :evergreen_tree:
Ecosystems
Tundra
Located primarily north of the Arctic Circle
Consist of vegetation
Frozen soil
Taiga
Cold-climate forests
Sub-arctic climate
Located in the northern latitudes
Largest terrestrial ecosystem on the planet
Desert
Barren landscape
Weathering
Hostile living conditions
Lack of vegetation
Unprotected surface is exposed
Denudation
Tropical Rainforest
Consists of half of all living animal and plant species on the planet
Most threatened ecosystem
Large-scale fragmentation
Logging
Agricultural clearance
Grassland
Vegetation dominant
Poaceae
Grasses
Legumes
Occur naturally on all continents except Antarctica
Most biodiverse habitats on small spatial scales
Defaunation
Extinction of animal populations
Disappearance of species
Declines in abundance
Human impact
Overexploitation
Game (hunting)
Poaching
Overhunting
Reduced population density
Habitat destruction and fragmentation
Agriculture
Mining
Logging
Hydroelectric dams
Urbanization
Invasive species
Human colonisation & agriculture
Species are distributed outside native range
Ecological damage
Human-facilitated introductions
Dispersal agents
Deliberate
Accidental
Threaten biological diversity
Competitive exclusion
Niche displacement
Hybridisation
Homogenisation
Environmental Degredation
Deterioration
Resource depletion
Air
Water
Soil
Habitat destruction
Extinction of wildife
Pollution
Biodiversity loss
Human overpopulation
Overconsumption
Intensive agriculture
Impacted 68% of vertebrate wildlife since 1970
One million species of plants & animals face extinction
Biomass
Establishment of agriculture
Vegetation
Reduced by half
Terrestrial animal communities
20% decline on average
