For example, the weed Crepis sancta, found in France, has two types of seed, heavy and fluffy. The heavy ones land near the parent plant, whereas the fluffy seeds float further away on the wind. In urban environments, seeds that float far often land on infertile concrete surfaces. Within about 5-12 generations the weed has been found to evolve ...
Humans have the potential to induce patchy food distribution, which can promote animal aggregation by attracting a high number of animals to common food sources; “this aggregation may increase the spread of parasites transmitted through close contact; parasite deposition on soil, water, or artificial feeders; and stress through inter‐ and ...
Megacities are a common backdrop in dystopian science fiction, with examples such as the Sprawl in William Gibson's Neuromancer, [58] and Mega-City One, a megalopolis of between 50 and 800 million people (fluctuations due to war and disaster) across the east coast of the United States, in the Judge Dredd comic.

Organizations are working tirelessly to rescue animals, and as local shelters reach capacity, some organizations are taking animals to nearby states; for example, the charities Best Friends Animal ...
A megalopolis (/ ˌ m ɛ ɡ ə ˈ l ɒ p ə l ɪ s /) or a supercity, [1] also called a megaregion, [2] is a group of metropolitan areas which are perceived as a continuous urban area through common systems of transport, economy, resources, ecology, and so on. [2]
In the context of urban rewilding, corridors connect habitats so that animals in cities can freely move throughout the urban environment. [2] Restored bodies of water or green pathways are examples of corridors. [2] An example of corridors can be found in Hebei Province, China. [2]
