“…Plant “stress” in urban areas has been attributed to air pollution and an altered hygrothermal environment that may increase a plant's susceptibility to insect attack (Houston 1985, Schmitz 1996, Oksanen et al . 1996, Kozlov 1996, van Rensburg et al . 1997, Speight et al .…”

“…Increases in insect abundance in urban areas are attributed to such causes as higher plant ''stress'', lower diversity plantings (mono-culture), and altered natural enemy complexes in urban regions (Root 1973, Kareiva 1983, Houston 1985, Dreistadt et al 1990, Hanks and Denno 1993. Plant ''stress'' in urban areas has been attributed to air pollution and an altered hygrothermal environment that may increase a plant's susceptibility to insect attack (Houston 1985, Schmitz 1996, Oksanen et al 1996, Kozlov 1996, van Rensburg et al 1997, Speight et al 1998). Conversely, a lack of plant stress caused by increased fertilization, water availability, and sunlight has also been hypothesized to increase population densities of insect species in urban areas (Marino et al 1993).…”

2003. The effect of urbanization on the quality of remnant habitats for leaf-mining Lepidoptera on Quercus agrifolia. -Ecography 26: 777-787.Previous studies suggest that urbanization alters the abundance and species richness of native insects on remnant habitat patches. However, the effects of urbanization on biological communities caused by habitat loss and fragmentation have not been separated from effects caused by altered habitat quality within remnant habitats or by the nature of the urban matrix. To test for an effect of urbanization acting via altered habitat quality or matrix characteristics, we controlled for the effects of habitat loss and fragmentation by comparing remnant habitat patches in urban and agricultural regions experiencing similar levels of habitat loss and fragmentation. We studied the species richness and abundance of the community of leaf-mining Lepidoptera on Quercus agrifolia in the San Francisco Bay Area. We measured the extent of five land-use types within a 500 m radius of each study patch. We built generalized linear models to determine if the extent of any of the landscape variables was associated with the species richness and abundance of the leaf-miner community. The extent of urbanization was not associated with species richness or total abundance. However, the abundance of three species of leaf-mining moths was associated with the extent of urbanization, but not in a consistent pattern. The abundances of Stigmella 6ariella and Bucculatrix albertiella were higher and the abundance of Dryseriocrania auricyanea was lower at highly urbanized sites. The absence of a consistent association between urban land-use and both species richness and abundance indicates that the effects of urbanization on the community of leaf-mining moths of Q. agrifolia do not differ from the effects of replacing and fragmenting habitats with similar amounts of agricultural land-uses.

The Global South has suffered an accelerated population and urban growth. This has created multiple impacts at the regional level such as erosion, soil degradation and biodiversity loss, as well as temperature increase in the cities causing urban heat islands. Bogotá, the capital of Colombia, is one of the largest cities in the Global South and in the last five decades has undergone a rapid urban transition, impacting surrounding ecosystems. However, little is known about how urbanization affects the local flora. To understand how plants are responding and adapting to urbanization processes in the city of Bogotá, we used a land cover gradient of urban, peri-urban and rural areas, and four plant functional traits (leaf area [LA], specific leaf area [SLA], leaf dry matter content [LDMC] and wood density [WD]). We analyzed 16 species shared in at least two land covers. Although urban and peri-urban areas had higher temperatures and higher LDMC and lower SLA values than rural areas, there were no significant differences in functional traits between land covers. Some species showed significant changes between land covers, indicating that there is a species-specific response to urbanization. Considering the need for urban areas to prioritize species that promote cooling and exhibit resistance to stress, as well as the capacity to adapt to climate change, it is essential to include plants possessing different combinations of functional traits.
