Question

what are anthropogenic ecosystem

Answer 1

The primary driving force influencing the entire assemblage of urban wildlife isHomo sapiens. In fact, the overwhelming influence people have on the wildlife found in anthropogenic ecosystems argues for consideration of them as an urban ‘keystone’ species. An ‘urban’ area is defined as having an increased density of human-created structures and people relative to areas surrounding it. Humans have the ability to alter both the abiotic and biotic conditions and the structure and function of ecosystems converting undeveloped land into anthropocentric habitats. Vertebrate species that survive in urban settlements have distinct characteristics. Inventories of fish, amphibian, reptile, and non-human mammal species in cities suggested these species are more similar than different. The built environment — buildings, communication towers, roads, and bridges — are either a detriment, a benefit, or both to the survival of wildlife species. One of the greatest hazards to both humans and wildlife is the witches’ brew of toxic chemicals present in some urban soils, in the air, and in water, and the increasing presence of urban wildlife points to the incredible resiliency of these species. The 1986 Chernobyl, Russia, nuclear plant meltdown site offers a unique opportunity toobserve changes in urban vertebrate assemblages once humans are no longer present; the area almost immediately ceases to be an anthropogenic ecosystem.
