  2. Urban evolution - Wikipedia

    en.wikipedia.org/wiki/Urban_evolution

    In the context of Earth's living history, rapid urbanization is a relatively recent phenomenon, yet biologists have already observed evolutionary change in numerous species compared to their rural counterparts on a relatively short timescale. [1] [2] Strong selection pressures due to urbanization play a big role in this process.

  3. Urban ecology - Wikipedia

    en.wikipedia.org/wiki/Urban_ecology

    Observations on the impact of urbanization on biodiversity and species interactions are consistent across many studies but definitive mechanisms have yet to be established. Urban ecology constitutes an important and highly relevant subfield of ecology, and further study must be pursued to more fully understand the effects of human urban areas ...

  4. Rural-Urban gradient - Wikipedia

    en.wikipedia.org/wiki/Rural-Urban_gradient

    In biodiversity, the rural-urban gradient is sometimes also used to describe the species richness distribution along the gradient. It is known that for most groups of organisms when urbanization is high, species richness decreases. [7] However, when urbanization is at a low to medium level, species richness tends to increase. [7]

  5. Urban ecosystem - Wikipedia

    en.wikipedia.org/wiki/Urban_ecosystem

    This rapid urbanization can have both positive and negative impacts. On the one hand, cities can provide economic opportunities, access to healthcare and education, and a high quality of life for residents. On the other, increased urbanization exacerbates the struggles of pollution, loss of green spaces, loss of biodiversity, and more. [8]

  6. Urbanization and Global Environmental Change Project

    en.wikipedia.org/wiki/Urbanization_and_Global...

    The Urbanization and Global Environmental Change Project (UGEC) is one of the core research projects of the International Human Dimensions Programme on Global Environmental Change (IHDP). UGEC aims to understand the bi-directional interactions between urbanization and global environmental change .

  7. Urban wilderness - Wikipedia

    en.wikipedia.org/wiki/Urban_wilderness

    The nineteenth and twentieth centuries saw the urbanization of cities. Jacob Riis and other reformers fought for parks in urban areas. [5]While many societies had traditions of intense urban plantings, such as the rooftops of pre-conquistador Mexico City, these traditions did not reemerge on a larger scale in the industrialized world until the creation of naturalistic urban parks, such as the ...

  8. Urban forestry - Wikipedia

    en.wikipedia.org/wiki/Urban_forestry

    Urbanization holds potential solutions to achieve high levels of biodiversity when managed correctly. In the United States, the Endangered Species Act's language acts as a means to protect not only listed species but also the conservation of their habitats to sustain them, many of which are found in urban areas.

  9. Edge effects - Wikipedia

    en.wikipedia.org/wiki/Edge_effects

    As the edge effects increase, the boundary habitat allows for greater biodiversity. Urbanization is causing humans to continuously fragment landscapes and thus increase the edge effect. This change in landscape ecology is proving to have consequences. [ 2 ]
