Chloropicrin fumigation, Eptam 7-E (EPTC) herbicide, and Paenibacillus macerans seed treatments were evaluated as alternatives to fumigation with methyl bromide/chloropicrin for loblolly pine (Pinus taeda L.) seedling production at three nurseries in the southern United States. A treatment of metam sodium/chloropicrin was also evaluated at one nursery. Seedling density was unaffected by fumigat...

Pythium species are important soilborne pathogens occurring in the forest nursery industry of the Pacific Northwest. However, little is known about their genetic diversity or population structure and it is suspected that isolates are moved among forest nurseries on seedling stock and shared field equipment. In order to address these concerns, a total of 115 isolates of three Pythium species (P....

Exposure to bioaerosols in occupational settings is associated with a range of adverse health effects. The aim of this study was to investigate the exposure levels to dust and endotoxin of people working in two cucumber nurseries and two tomato nurseries. Exposure was measured for greenhouse workers (n = 70) mainly working on harvesting cucumbers and tomatoes and clearing the plants after the h...

Smalltooth sawfish Pristis pectinata use southwest Florida nurseries during at least their first 2 to 3 yr, and understanding region-specific habitat use patterns is important for effective management. Research occurred in 2 nurseries within the Charlotte Harbor estuarine system: the Caloosahatchee River, a highly human-altered nursery, and a more natural nursery, the Peace River. Between 2010 ...

OBJECTIVE To determine longitudinal outcomes and contributors to parental stress and coping in mothers of very low-birth-weight (VLBW) children. DESIGN Prospective cohort follow-up of high-risk VLBW children (n = 113), low-risk VLBW children (n = 80), and term children (n = 122) and their mothers from birth to 14 years. SETTING Recruitment from level III neonatal intensive care and term nur...

Few criteria exist for identifying which babies merit special nursing care, and many asymptomatic babies are offered such care unnecessarily. Birth weight is usually used to identify babies in need of special care at birth, but gestational age is a better discriminator. Babies of more than 35 weeks' gestation do not normally require admission to a special care nursery. Those preterm babies who ...
