COS 113-1
While urban ecosystems can host surprisingly high levels of biodiversity, there are still many shifts in the characteristics of the biotic communities found in cities. In particular, urban species communities tend to become more functionally and phylogenetically homogeneous than non-urban communities.   ...

Thurs, Aug 13, 11:10 AM, 348 BCC
COS 113-10
... theoretical frameworks describing urban streams have focused on dissolved nutrient export, urban stream ecosystems are also dynamic in terms of GHG production in time and space. ... we hypothesized that nitrogen-loaded streams are likely to produce more N2O than streams with low N, and those draining stormwater management wetlands will produce relatively more CH4.
Nicole Voelker, Chris Swan

Thurs, Aug 13, 4:00 PM 348 BCC
COS 132-8
... Residential lawns are generally highly managed and are very common in the urban landscape, and therefore are a good system in which to study the potential homogenizing effects of urban land use and management. We measured plant species in residential lawns in seven climatically distinct cities ... to assess how the vegetation structure and composition in residential lawns compared ...

Have you noticed urban/suburban landscapes seem to look similar in cities—lawns and rows of single-family homes?  Or you've noticed how differently you manage your yard compared neighbors. We hypothesize these patterns are part of the American residential macrosystem, a homogenous social/ecological system distributed across diverse geographies.

Urban soils provide many of the same ecosystem services as “natural” or agricultural soils e.g. decomposition and nutrient cycling, water purification and regulation, medium for plant growth, and habitat for organisms. Soils in cities are disturbed, transported, heavily managed and even created. Urbanization is portrayed as one of the leading causes of biodiversity loss and ample evidence from large organisms supports this claim.  ...

Tues, Aug 11 8:00 AM - 11:30 AM, 340 BCC
OOS 21
Biodiversity as an ecological concept is difficult for people to personally experience due in part to the fact that the majority of humans now live in urban areas. Moreover, the role of extremely diverse soil biota is often overlooked in assessing soil ecosystem services. Indeed, for much of the terrestrial ecosystems of the world, soil community structure and function reflect both natural and human disturbance and stress.  ...

OOS 21-8
Knowledge on the effects of urbanization on ecosystems across regional, continental and global scales is scarce. To address this issue, ecological networks are useful tools to foster international collaboration among scientist towards common goals. Yet, these networks require intensive measurements and experiments, are cost prohibitive, thus hindering broad participation ...

OOS 30-2
Urbanization alters the structure and function of the critical zone by changing the way that water moves across the landscape and affecting connections between different components of the landscape. Addition of impervious surfaces to urban watersheds decreases groundwater recharge and increases the energy and amount of stormflow to streams.  These changes alter the coupling between uplands, riparian zones and streams ...

OOS 45-7
A rich array of social science disciplines, including such fields as sociology, geography, anthropology, economics, environmental psychology, landscape architecture, and urban planning and design, have developed bodies of knowledge and theory about human life and the environment in cities with work stretching back over at least a century. Ecologists have come to the study of cities far later in the game ...

In 1906, Maryland became just the third state to hire a professionally-trained forester. Over the course of a career that spanned 36 years Fred Besley introduced a variety of conservation programs that would be adopted both regionally and nationally. Baltimore’s aspiration to become known as the “city of a million trees” was never fully realized. Likewise, the city has struggled to produce an equitable distribution of trees.

How can ecology and community-based planning inform one another? Urban ecologists, as they engage with the human-built environment, are trying to integrate social components into their research methods and existing ecological theories, which were developed around fundamental biogeophysical drivers.
Morgan Grove, Dexter Locke

OOS 84-5
We have tested the idea of an Ecology of Prestige. This theory posits that housing styles, yard characteristics, tree and shrub plantings, and green grass can be considered social-ecological symbols, reflecting the type of neighborhoods in which people live. These social-ecological symbols can be interpreted as the outward manifestation of each neighborhood’s placement in a social hierarchy of group identity and social status in the urban patch mosaic. ...

The past decade has seen the maturation of the discipline of urban ecology. Whereas earlier urban ecological research focused on the obvious green components “IN” cities, a more comprehensive approach that investigates entire urban complexes as heterogeneous ecological systems - an ecology “OF” cities - has been added. …
Steward T. A. Pickett, Daniel L. Childers, Mary L. Cadenasso, Mark J. McDonnell, Weiqi Zhou
Mon, Aug 10, 1:30 PM. 308 BCC
SYMP 2-1
Since 1997, the contrast between ecology IN and ecology OF cities has been used to emphasize the increasingly interdisciplinary approach to urban ecosystems.  Ecology IN focuses on terrestrial and aquatic patches within cities, suburbs, …  Ecology OF the city, treats entire cities or landscape mosaics consisting of cities suburbs and exurbs as social-ecological systems. 
Morgan Grove, Rinku Roy Choudhury, Daniel L. Childers, Laura A. Ogden, Alexander J. Felson, Erika Svendsen

Mon, Aug 10, 4:10 PM. 308 BCC
SYMP 2-6
A recent addition to paradigms in stream ecology is the “urban stream syndrome,” which suggests that hydrological changes associated with impervious surfaces in cities drive the loss of ecological integrity. We synthesize findings from urban streams encompassing a wide range of city sizes and biogeoclimatic contexts.  This synthesis provides new insights to further explore the ecology in, of, and for developing approaches for sustainable streams.
