Although suburban healthcare providers may have more resources to address drug addiction, abuse, and overdose, preconceived ideas about suburban lifestyles may prevent them from providing proper ...
The urban ecosystem is a place of extremities and makes for fast evolution. Higher rates of phenotypic change have been observed in urban areas compared to natural and nonurban anthropogenic systems. [7] A field of study has emerged regarding urban evolution in which the adaptations of animals and plants to urban environments are studied.
Urban ecology is a relatively new field. Because of this, the research that has been done in this field has yet to become extensive. While there is still plenty of time for growth in the research of this field, there are some key issues and biases within the current research that still need to be addressed.
In France, an urban area (Fr: aire d'attraction d'une ville) is a zone encompassing an area of built-up growth (called an "urban unit" (unité urbaine) [41] – close in definition to the North American urban area) and its commuter belt . Americans would find the INSEE definition of the urban area [42] to be similar to their metropolitan area.
