BACKGROUND Cupressaceae pollen allergy is a worldwide winter pollinosis. Exposure to cypress pollen has increased enormously during recent decades, and cypress pollen allergy has become a major health problem, especially in Mediterranean countries. OBJECTIVES We aimed to evaluate the prevalence of cypress pollen sensitization and allergy in the Montpellier area and the symptoms presented by s...

Pond-cypress, a deciduous conifer, is a dominant canopy species in depressional wetlands of the southeastern Coastal Plain (SCP). Extensive premature decline and death of pond-cypress trees in central Florida have been attributed to hydroperiod alterations due to excessive withdrawals of ground water from the Floridan aquifer. One factor identified in the decline process is basal decay, which m...

The scaling relationship between height and diameter is important for understanding the dynamic patterns of tree growth and estimating the accrual of tree biomass. Metabolic ecology predicts that tree growth follows a universal scaling invariant relative to the height-diameter relationship (i.e., no variation based on taxonomy or resource availability). Comparing field data for different tree s...

the spherical mealybug (nipaecoccus viridis newsted) is one of the most harmful pest of citrus, oleander and mulberry in green space of shiraz region. this study was carried out to detect the population dynamics of this pest and the role of biotic and abiotic factors on it in 2007-2008. the spherical mealybug, in both years, started its activity from early may on citrus and oleander trees, but ...

Delottococcus aberiae De Lotto (Hemiptera: Pseudococcidae) is a mealybug of Southern African origin that has recently been introduced into Eastern Spain. It causes severe distortions on young citrus fruits and represents a growing threat to Mediterranean citrus production. So far, biological control has proven unsatisfactory due to the absence of efficient natural enemies in Spain. Hence, the m...

BACKGROUND Despite the fact that airborne pollen is an important factor in precipitating asthma attacks, its implication in increases of epidemic asthma in usual meteorological conditions has not been reported. A study was undertaken to estimate the relationship between various types of aeroallergens and seasonal epidemic asthma in the region of Madrid, Spain. METHODS A case-control study was c...

A computer software system is described that uses digitized color information from aerial color infrared transparencies to detect the presence of citrus mealybug (Pseudococcus citri Risso), brown soft scale (Coccus hesperidum L.), and Rio Grande gummosis in individual citrus trees. The color coordinates at each spatial point, and color differences at adjacent points are used to locate the trees...

The effect of storing cooked Bengal and Cypress milled rice at –13, 3, 20, and 36 °C on texture and degree of starch retrogradation was investigated. Cooked rice firmness increased, while stickiness decreased, during storage at –13 and 3 °C. Starch retrogradation, measured with a differential scanning calorimeter, was observed for both cultivars during storage at –13 and 3 °C, but not at 36 °C....

Land use change can result in complex environments of varying habitat quality and permeability that directly indirectly influence the effectiveness natural areas for wildlife conservation. To assess how isolation degradation protected may affect long-term conservation efforts across range a sensitive subspecies, we used multiscale occupancy analysis, species distribution modeling, circuit theor...

Forest structural diversity is related to stability, biodiversity, adaptability and resilience, as well productivity of forest ecosystems. In this study, we characterized the diverse type groups in southeastern Outer Coastal Plains Mixed Province United States. We utilized data from 13,658 Inventory Analysis (FIA) plots across region classified them on basis group (i.e., longleaf-slash pine, lo...
