While I would direct any serious student of the lawn (or of vernacular culture more generally) to these excellent works, this book begins where they leave off While I draw heavily on the insights of these previous explorations, the volume diverges in its emphasis on explaining the work the lawn does on us as individuals, communities, and cities. The book also adopts an approach that focuses especially on broader political economy, since while the lawn is of course a fundamental product of American imagination-a symbol—it is also a vast and coercive economy. More specifically, monocultural lawn cultivation imposes a set of economic relationships between grasses, weeds, chemicals, companies, and people. 

Gradients of nutrients and oxygen in biofilms additionally promote high diversity, which may ultimately result in functional differences of the bacterial community in biofilms compared with free-floating bacteria. Additionally, increased species diversity may provide spatial and temporal niches not available within monocultures or may create microenvironments within the biofilm (Gieseke et al., 2001 Whiteley et al., 2001). These thoughts reinforce the need for community-level biofilm studies as opposed to monocultures. 

The dinitroaniline herbicides, trifluralin and pendimethalin, have been utilized in greater than 80% of the cotton acreage in the Southern United States because of their very effective weed control in this crop (1). Many of these fields are essentially in cotton monoculture and hence the continued use of these herbicides has constantly selected out those weeds most tolerant of these herbicides. Under such a selection pressure, the appearance of weed biotypes resistant to dinitroaniline herbicides is expected (2). The first report of a resistant biotype did not appear until 1984, Mudge si gl. (3) described the occurrence of dinitroaniline-resistance in Eleusine indica in counties in South Carolina where cotton is extensively cultivated. Since that initial report, dinitroaniline-resistant Eleusine has been detected throughout the midsouth (H. LeBaron, personal communication).
