Forested wetlands are in decline, as are many species that are obligate residents. Big Cypress fox squirrels (BCFS; Sciurus niger avicennia) are a threatened endemic to wet pine and cypress forests in southwestern Florida. The region is characterized by development resulting in habitat loss, habitat fragmentation, and hydrological change that influence the quality of these wet forests. Through ...
BACKGROUND non-injective routes of immunotherapy in respiratory allergy have being proposed as an alternative to conventional immunotherapy. We carried out a study to evaluate the clinical efficacy and effects sublingual immunotherapy (SLIT) in patient with Cupressaceae pollen respiratory allergy. METHODS twenty patients with Cupressaceae pollen (C. sempervirens) rhinoconjunctivitis, mild ast...
Interpopulational gene flow within a species can reduce population differentiation due to genetic drift, whereas genetic exchange among taxa can impede speciation. We used allozyme data to estimate gene flow within and among geographic races and species of perennial herbs in the Ipomopsis aggregata complex (Polemoniaceae). Estimates of interpopulational gene flow within taxa from two methods (F...
OBJECTIVES In this multicenter survey, we assessed the impact of sensitization to cypress in atopic patients in Italy and determined whether cypress pollen concentration changed over time. METHODS Allergists were required to collect the results of 100-200 consecutive skin prick tests (SPTs) performed during 2012. Seasonal symptoms were also recorded, as were airborne cypress pollen concentrat...
The impetus behind this study is to discover the aesthetic and semantic patterns of the cypress tree and show how this element has been employed by Iranian artists. The question of this research is how a constant element (the cypress tree) has been transfigured in different Iranian arts. Four categories of miniature, carpet, textile and architecture decoration. The present research is qual...
The morphology of silk produced by recluse spiders (Loxosceles arizonica) was investigated by scanning electron microscopy, atomic force microscopy, and transmission electron microscopy. This silk consisted entirely of very long, thin ribbons of width 2-4 microm and thicknesses of no more than 40 nm. The correspondence in shape and dimension between the silk ribbons and the elongated aperture o...
Let X/K be an absolutely simple abelian variety over a number field; we study whether the reductions Xp tend to be simple, too. We show that if End(X) is a definite quaternion algebra, then the reduction Xp is geometrically isogenous to the self-product of an absolutely simple abelian variety for p in a set of positive density, while if X is of Mumford type, then Xp is simple for almost all p. ...
The widely distributed Pinus subsection Ponderosae is a species complex that has a transition zone among taxa in the southwestern United States. In southern Arizona and New Mexico at least two recognized taxa, Pinus ponderosa var. scopulorum and Pinus arizonica or P. ponderosa var. arizonica, are known to coexist in close proximity. In this study, we report the existence of populations where th...
Fifteen cypress domes located within an extensively managed slash pine plantation were characterized according to the presence and nature of ditches and berms. Mean water depth and hydroperiod for the year 1978-79 were generally greater in the domes without these alterations. Cypress importance values were significantly higher in the unaltered, wet domes whereas hardwood importance values and s...
Rice blast, an erratic niche disease incited by Magnaporthe grisea Cav., frequently limits rough rice yields and grower cultivar options in Arkansas rice production areas. Scientists poorly understand why some blast-susceptible varieties such as ‘Newbonnet’, ‘LaGrue’, ‘Mars’, and ‘Cypress’ become increasingly more blast resistant if grown in continuously flooded soil. A greenhouse depth-of-floo...
