A lizard may bask in the sun on top of a stone 19 20 AGRICULTURAL AND URBAN AREAS wall. Since it is unable to generate its own body heat in the way that mammals do, it needs to seek energy from the Sun to keep its body temperature high enough to sustain its activity. A mountain lion may do the reverse and seek the cool of a cave during the hot day, avoiding the problem of overheating. Each is seeking a particular microclimate that serves its purpose. In the course of their evolution, human beings have behaved in precisely the same way.

In practice, of course, winds vary in direction and speed, so all cities are occasionally subject to these wind-tunnel effects, Chicago being a proverbial example. Thus the city street behaves almost like a canyon. City wildlife responds accordingly to this similarity. The patterns of wind movement and turbulence in cities are also important when we consider the dispersal of pollutants, particularly those emitted by vehicles on the streets. A lack of air turbulence at street level can result in the buildup of gaseous emissions and small particles at ground level, for they are not being dispersed by air movements.

Small lakes and ponds in the city parks add to the mosaic of habitat patches in the city. Do these patches, like those habitat fragments in the rural countryside, also obey the rules of island biogeography? Generally speaking, the answer seems to be yes. Larger lakes usually support more species of ducks than small ones. Also, if you check vacant lots for invasive plants, you will find more species on the larger lots. It is also true that short distances between such habitat patches lead to faster invasion and richer habitats.
