Conservation plantings of native wildflowers were established adjacent to highbush blueberry (Vaccinium corymbosum L.) fields to test the hypothesis that provision of resources for natural enemies increases their abundance in adjacent crop fields without increasing the abundance of pest insects. For two growing seasons, natural enemies and herbivorous insects were sampled in fields with flower...
A mail survey of residents in suburban northern Westchester County, New York was conducted to determine the nature and extent of deer damage in the county, the importance of deer damage relative to other deer-human interactions, and residents' perceptions of costs and benefits associated with the deer herd. The estimated cost of damage to plantings was quite high, $6.4 million to $9.5 million (...
The developmental and temporal succession patterns and disturbance responses of phyllosphere bacterial communities are largely unknown. These factors might influence the capacity of human pathogens to persist in association with those communities on agriculturally-relevant plants. In this study, the phyllosphere microbiota was identified for Romaine lettuce plants grown in the Salinas Valley, C...
Solid waste landfills have become rather commonplace in urbanized and industrialized regions of the world. If designed, managed, and restored properly, they can be converted to useful land uses. However, restoration of woody vegetation can be difficult when animal damage occurs. Numerous species of voles occur throughout the northern hemisphere and several may become serious pests of restoratio...
Increased homogeneity of agricultural landscapes in the last century has led to a loss of biodiversity and ecosystem services. However, management practices such as wildflower borders offer supplementary resources to many beneficial arthropods. There is evidence that these borders can increase beneficial arthropod abundance, including natural enemies of many pests. However, this increase in loc...
Polybrominated diphenyl ethers (PBDEs) are potentially harmful and persistent environmental pollutants. Despite evidence that soils are a major sink for PBDEs, little is known regarding their behavior in this medium. An environmentally relevant level of a commercial penta-BDE mixture (75 microg kg(-1)) was added to topsoil, and the extractability of three congeners (BDE-47, -99, and -100) was m...
Stepping-stone restoration plantings can reconcile conservation goals and local land-use needs in highly fragmented ecosystems. We explored how initial planting composition influences recruiting plant species density, diversity, abundance, forest structure a 13-year-old experiment Los Tuxtlas, Veracruz, Mexico. Treatments included eight fenced with animal-dispersed species, wind-dispersed unpla...
Community orchards could play a valuable role as nature-based solutions to complex challenges we face today. In these unique plantings, variety of nut- and fruit-producing trees berry shrubs are often established together on public spaces provide the community with healthy, fresh food. Interest in plantings has been increasing United States, even more so since COVID-19 pandemic highlighted vuln...
