Secular and Faith-based Organisations as Reliable Information Sources for Residents of Environmentally Stressed Neighbourhoods

A sample of 873 residents of Accra, Ghana, and 504 residents of the state of New Jersey, USA, stratified by type of neighbourhood was gathered in order to determine the sources of information residents rely on for accurate information about their neighbourhoods. In both countries residents relied most heavily on personal contacts, television and radio, and much less on community organisations. Residents who rely on many sources for reliable information tend to have lived in their neighbourhood for a long time and to be more engaged in neighbourhood activities than those who reach out to fewer sources. Those who rely on secular community organisations tend to mistrust science, experts and local officials. Those who rely on faith-based organisations are much more trusting of local officials but are even less trusting of science and experts than their counterparts. The implications of these results for building and sustaining community organisations are discussed.     

The BOR syndrome and renal agenesis-prenatal diagnosis andfurther clinical delineation

This is the first report of prenatal diagnosis of a fetus with brachio-oto-renal dysplasia (BOR) syndrome with right-sided renal agenesis and severe left hypoplasia. The father of this fetus had malformed external ears, a left-sided preauricular pit and branchial cyst, and bilateral mild to moderate deafness without a demonstrable renal anomaly. This family highlights the variable expressivity seen in the autosomal dominant BOR syndrome, the importance of genetic counselling for families with BOR syndrome, and the aetiologic heterogeneity of renal agenesis.     

Spontaneous resolution of a cystic hygroma in a fetus with Turner syndrome

The prenatal detection of a cystic hygroma (CH) in a fetus with a 45,X karyotype is described. The cystic hygroma underwent spontaneous resolution and a healthy baby with Turner syndrome was subsequently born. The implications for genetic counselling are discussed.     

Responses of three grass species to creosote during phytoremediation

Phytoremediation of creosote-contaminated soil was monitored in the presence of Tall fescue, Kentucky blue grass, or Wild rye. For all three grass species, plant growth promoting rhizobacteria (PGPR) were evaluated for plant growth promotion and protection of plants from contaminant toxicity. A number of parameters were monitored including plant tissue water content, root growth, plant chlorophyll content and the chlorophyll a/b ratio. The observed physiological data indicate that some plants mitigated the toxic effects of contaminants. In addition, in agreement with our previous experiments reported in the accompanying paper (Huang, X.-D., El-Alawi, Y., Penrose, D.M., Glick, B.R., Greenberg, B.M., 2004. A multi-process phytoremediation system for removal of polycyclic aromatic hydrocarbons from contaminated soil. Environ. Poll. doi: 10.1016/j.envpol.2003.09.031), PGPR were able to greatly enhance phytoremediation. PGPR accelerated plant growth, especially roots, in heavily contaminated soils, diminishing the toxic effects of contaminants to plants. Thus, the increased root biomass in PGPR-treated plants led to more effective remediation.     

Preferences for alternative risk management policies at the United States major nuclear weapons legacy sites

A survey of 1351 people who lived within 50 miles of one of six US Department of Energy nuclear weapon sites showed that the vast majority of residents prefer strong public health surveillance and land use controls. The sample was stratified so that the same number of responses was obtained at each site. The strongest correlates of wanting the DOE to restrict on-site activities and maintain and expand its surveillance programs were worries about DOE activities on the site, as well as how those activities could damage the off-site environment. Notably, the exceptions, that is, those who demanded less from the DOE and were not particularly worried about the DOE's activities, tended to live near the site, many worked there or knew people who did, and had high socio-economic status, and trusted the DOE. The findings are mostly, but not entirely, consistent with expectations drawn from the risk perception and organizational trust literatures. The challenge is how to establish a stewardship program that represents a consensus among state and local government, community advisory boards and the public that remediation can go on at the same time that some waste is managed on-site until suitable technologies can be safely deployed, which at some sites means 100 years or in perpetuity.     

How much do people who live near major nuclear facilities worry about those facilities? Analysis of national and site-specific data

Large nuclear waste management, laboratory and electric power generating complexes are a daunting challenge for state, regional and local planners. A survey of 2101 residents who lived near 11 nuclear power plants and US Department of Energy (DOE) nuclear waste management sites and laboratories was conducted to determine how much nearby residents worried about accidents and chronic emissions at the nuclear sites, how much they trusted the sites’ responsible parties, and actions that they wanted responsible parties to take to reduce public concern. Six hundred other people who lived elsewhere in the US were a comparison group. Nuclear site-related issues were a greater concern among the 2101 who lived near the sites than the comparison group. Yet many were more concerned about global warming, traffic congestion, and loss of open space than nuclear technologies. Monitoring the environment and people were the actions deemed most likely to reduce public concern. The results pose a challenge to owner-operators of nuclear facilities, government entities and especially to locally based environmental planners and managers to establish partnerships with each other and diverse communities that will allow them to manage some of these risks for decades and in some cases into perpetuity.     

Guidance for determining the best disposition of large tracts of decommissioned land

Many government agencies and other organizations hold large tracts of surplus land. Some are investigating ways to lower expenses by selling the land or transferring management responsibility. There is no generally recognized process used to decide what land can be decommissioned and what future use would be best. This paper provides guidance for land‐use decisions in the form of a checklist. The checklist questions address both the socio‐economic resources and current land use in the region, and the ecological resources and suitability of the tract itself. The answers will clarify regional public needs and the economic and ecological values of the land.     

Search behavior of the checker-throated antwren foraging in aerial leaf litter

Summary Checker-throated antwrens (Formicariidae: Myrmotherula fulviventris) live in lowland neotropical forests and forage from dead curled leaves in the understory. Because they search each leaf individually they provide an opportunity to study the use of potential visual cues by an insectivorous bird. Long and highly curled leaves contain the most arthropods and checker-throated antwrens were more successful when foraging at those leaves. Yet, they used leaves at random with respect to these potential cues. Antwrens spent longer searching for arthropods in each highly curled leaf than in less curled leaves. Because of this additional search time, prey capture success per unit foraging time was only slightly greater for highly curled leaves than at the average dead leaf in the aerial leaf litter. Thus, the cues that antwrens could use to locate richer leaves are those features that obscure the prey from avian predators. Unlike other foraging systems, the antwrens appear to have no reliable cues indicating more profitable foraging sites.Address for correspondence     

Allozyme and morphological evidence for a newly introduced species of Aurelia in San Francisco Bay,California

The jellyfish Aurelia aurita (Linnaeus, 1758) is usually considered to be a cosmopolitan species. Aurelia sp. medusae observed at Foster City, San Francisco Bay, California, USA, since 1988 are morphologically distinct from Aurelia sp. collected 200 km away in Monterey Bay, but are morphologically similar to aquarium-cultured Aurelia sp. from Japan. They differ consistently in radial canal morphology. In allozyme electrophoresis, significant differences at 12 of 14 polymorphic loci strongly suggest that Aurelia sp. from Foster City and Tokyo Bay belong to one species, while Aurelia sp. from Monterey Bay and Vancouver Island belong to a second species. We propose that Aurelia sp. at Foster City is a recent introduction, possibly from Japan via ships' ballast water. The identities and taxonomic affinities of the two Aurelia defined in this study, and their relationships with the Linnaen A. aurita described from the North Atlantic, will require genetic and morphological study of the currently recognized species A. aurita and A. limbata (Brandt, 1838) from several zoogeographical provinces.     

On the Decline of the Rusty Blackbird and the Use of Ornithological Literature to Document Long-Term Population Trends

Abstract: Unlike most North American blackbirds, Rusty Blackbirds (  Euphagus carolensis ) have shown steep population declines. Declines of approximately 90% are indicated for three recent decades from the Breeding Bird Survey, Christmas Bird Counts, and Quebec Checklist Program. Analyses of abundance classifications in bird distribution books and annotated checklists reveal an overlooked but long-term decline dating back to at least the early part of this century. Rusty Blackbirds were described as very common to abundant in 56% of the pre-1920 published accounts, 19% of the 1921–1950 accounts, and only 7% of the post-1950 accounts. Rusty Blackbirds were described as uncommon in none of the pre-1950 accounts, 18% of the 1951–1980 accounts, and 43% of the post-1980 accounts. A similar pattern was found for analyses based on local checklists. Destruction of wooded wetlands on wintering grounds, acid precipitation, and the conversion of boreal forest wetlands could have contributed to these declines. Systematic analysis of regional guides and checklists provides a valuable tool for examining large-scale and long-term population changes in birds.
