Ecological and social Interactions in urban parks: bird surveys in local parks in the central Arizona-Phoenix metropolitan area
Our central objective is to use small, neighborhood parks in Phoenix to study: (1) the ways in which ecological processes are influenced by human values, use, and management; and (2) the ways in which human attitudes and activities, and the services valued by humans, are influenced by ecological characteristics and processes. Elucidating this coupling in Phoenix parks will itself be a significant step towards understanding the complexities of human-nature interactions. The information gathered in addressing the central objective, though, can and should be used to assess potential trajectories for ecological processes. Our second objective is to develop trajectories for potential changes in ecosystem services in the Phoenix metropolitan area, given economic and demographic trends, and given the signal of human-nature interactions among different social groups.
Tree health analysis in the Phoenix Metropolitan Area
Urban trees contribute significantly to human health and environmental quality but assessments of their health are rare. This project involved developing an urban tree health monitoring protocol for use in the Southwestern US and using it to conduct field assessments of urban tree health in the Phoenix urban ecosystem during the winter/spring of 2006. Field manuals prepared by the USDA Forest Service for use in monitoring urban forest health (Cumming et al. 2001) were adapted to reflect the unique stresses and diseases that occur in urban areas in the southwestern US. Tree health was then assessed using a subset of field plots that have been established as part of the Survey 200 project and NPP intensive monitoring project as a foci. Ten to fifteen trees were assessed at each site for general tree health including canopy condition, canopy dieback and disease and pest problems. Abiotic problems were also assessed including stress problems, nutrient deficiency symptoms, improper pruning practices, trunk damage and girdling.
Bird surveys along the Salt River in and near the greater Phoenix metropolitan area: 2012-2013
Waterways are often the focus of restoration efforts in urban areas. In arid regions, passive discharge of urban water sources may stimulate the recovery or growth of wetland and riparian features in dewatered or ephemeral aquatic systems. In the greater Phoenix metropolitan area (GPMA), sections of the Salt and Gila Rivers have been the targets of active restoration through seeding, planting, and irrigation. At the same time, revegetation has occurred in some sections of the rivers in response to runoff from urban water sources (e.g., storm drains). This dataset catalogs the results of bird surveys conducted at several locations along the Salt River in and around the GPMA from March 2012 through October 2013. Survey locations include riparian areas in urban and non-urban locations that have been (actively) restored or have revegetated in response to urban runoff, and that feature ephemeral or perennial sources of water.

Movement paths of common noctule bats in the Berlin metropolitan area
<p> </p> <p>Cities are a challenging habitat for obligate nocturnal mammals because of the ubiquitous use of artificial light at night (ALAN). How nocturnal animals move in an urban landscape, particularly in response to ALAN is largely unknown. We studied the movement responses, foraging and commuting, of common noctules (<i>Nyctalus noctula</i>) to urban landscape features in general and ALAN in particular. We equipped 20 bats with miniaturized GPS loggers in the Berlin metropolitan area and related spatial positions of bats to anthropogenic and natural landscape features and levels of ALAN. Common noctules foraged close to ALAN only next to bodies of water or well vegetated areas, probably to exploit swarms of insects lured by street lights. In contrast, they avoided illuminated roads, irrespective of vegetation cover nearby. Predictive maps identified most of the metropolitan area as non-favoured by this species because of high levels of impervious surfaces and ALAN. Dark corridors were used by common noctules for commuting and thus likely improved the permeability of the city landscape. We conclude that the spatial use of common noctules, previously considered to be more tolerant to light than other bats, is largely constrained by ALAN. Our study is the first individual-based GPS tracking study to show sensitive responses of nocturnal wildlife to light pollution. Approaches to protect urban biodiversity need to include ALAN to safeguard the larger network of dark habitats for bats and other nocturnal species in cities.</p>
Data from: Interactions between demography, genetics, and landscape connectivity increase extinction probability for a small population of large carnivores in a major metropolitan area
The extinction vortex is a theoretical model describing the process by which extinction risk is elevated in small, isolated populations owing to interactions between environmental, demographic, and genetic factors. However, empirical demonstrations of these interactions have been elusive. We modelled the dynamics of a small mountain lion population isolated by anthropogenic barriers in greater Los Angeles, California, to evaluate the influence of demographic, genetic, and landscape factors on extinction probability. The population exhibited strong survival and reproduction, and the model predicted stable median population growth and a 15% probability of extinction over 50 years in the absence of inbreeding depression. However, our model also predicted the population will lose 40–57% of its heterozygosity in 50 years. When we reduced demographic parameters proportional to reductions documented in another wild population of mountain lions that experienced inbreeding depression, extinction probability rose to 99.7%. Simulating greater landscape connectivity by increasing immigration to greater than or equal to one migrant per generation appears sufficient to largely maintain genetic diversity and reduce extinction probability. We provide empirical support for the central tenet of the extinction vortex as interactions between genetics and demography greatly increased extinction probability relative to the risk from demographic and environmental stochasticity alone. Our modelling approach realistically integrates demographic and genetic data to provide a comprehensive assessment of factors threatening small populations.
Data from: Ambient noise tomography of upper crustal structures and Quaternary faults in the Seoul metropolitan area and its geological implications
<p class="0"><span><span><span>We investigate the upper-crustal seismic velocity structure in the Seoul metropolitan</span> <span>area, where about 20 million people live.
