Phytophthora ramorum is an aggressive Oomycete pathogen introduced into western North America and western Europe in the late twentieth century by the ornamental plant trade (Goss et al. 2011, Grünwald et al. 2012, Mascheretti et al. 2008, Prospero et al. 2007). The pathogen attacks a wide range of trees and shrubs, causing foliage blights and bleeding stem lesions both in nurseries and in the f...
Stable isotopes of carbon (δ13C) and oxygen (δ18O) in otolith cores (first 2 mo of age) of young-of-the-year (YOY) yellowfin tuna Thunnus albacares were used as natural tracers to predict the nursery origin of sub-adults (age-1) collected from the Hawaiian Islands. YOY fish were first collected from nurseries throughout the western and central Pacific Ocean (WCPO) to determine whether δ13C and ...
The distribution characteristics of soil organic carbon (SOC) and nutrients under different land-use types in Linyi City, East China, were studied. spatial SOC the relationship between analyzed using remote sensing interpretation sample analyses. results showed that was mainly stored drylands paddy fields. total nitrogen (TN) levels positively correlated for most land use types. There a positiv...
Effects of Marine Reserves versus Nursery Habitat Availability on Structure of Reef Fish Communities
No-take marine fishery reserves sustain commercial stocks by acting as buffers against overexploitation and enhancing fishery catches in adjacent areas through spillover. Likewise, nursery habitats such as mangroves enhance populations of some species in adjacent habitats. However, there is lack of understanding of the magnitude of stock enhancement and the effects on community structure when b...
Summary In order to examine the Summary .growth status or children in Tehran nurseries in comparison to the international standards, height and Weight in 526 boys and 557 girls 3 to 7 year old in 7 nurseries located in the wellto-do areas of the capital were surveyed and compared to the National Center for Health Statistics figures. 54.5% or the children were between -1 SD to + 1 SD weight fo...
Methylisothiocyanate (MITC) and chloropicrin (CP) are alternatives to methyl bromide for soil fumigation. However, surface transport of MITC emission has been cited as the cause for seedling damage in adjacent fields at several bare-root forest-tree nurseries. Field experiments were conducted at nurseries in Wisconsin and Georgia to measure air emissions of MITC and CP after fumigation. Four tr...
INTRODUCTION This study evaluated the expression of nonnutritive sucking habits and the presence of malocclusion in children using day nurseries' facilities. MATERIALS AND METHODS The 195 children (7-40 months) attending 18 public day nurseries were evaluated clinically in Ponta Grossa, Brazil. Statistical package software was used for descriptive, univariate, bivariate, and multiple logistic...
