Mesocarnivores are increasingly recognized as key drivers of community dynamics, but the effects of bottom-up and abiotic factors on mesocarnivore populations remain poorly understood. We evaluated the effects of snow conditions, prey abundance, and habitat type on the distribution of five sympatric mesocarnivore species in interior Alaska using repeated snow track surveys and occupancy modelli...
Abstract: as magnetic materials, semiconductors, pigments, catalysts, refractories and electronic ceramics. In this paper, wereported the preparation of NiAlThe resulting powder was chracterized by XRD, particle size analysis and SEM. The XRD patterns show that thecombustion technique was excellent to prepare single – phased cubic NiAlfound to be around 14 nm. From the particle size analysis, i...
Studies of the cellular pathogenesis mechanisms of pathogenic yeasts such as Candida albicans, Histoplasma capsulatum, and Cryptococcus neoformans commonly employ infection of mammalian hosts or host cells (i.e. macrophages) followed by yeast quantification using colony forming unit analysis or flow cytometry. While colony forming unit enumeration has been the most commonly used method in the f...
INTRODUCTION Bioaerosols are agents that can cause infection, allergy or induce other toxic effects in the human body. If the person exposed to such particles is not capable of their destruction or elimination from the body, the established chemical and physiological disorders can result in disease or death. The aim of this study was to assess the concentrations of bioaerosols in several wards ...
The Grain Impact Analyzer and Dust Accumulator (GIADA) instrument on board ESA’s Rosetta mission is constraining the origin of the dust particles detected within the coma of comet 67 P/Churyumov–Gerasimenko (67P). The collected particles belong to two families: (i) compact particles (ranging in size from 0.03 to 1 mm), witnessing the presence of materials that underwent processing within the so...
Factors that influence fungal communities in ambrosia beetle mycangia are poorly understood. The beetle that is responsible for spreading laurel wilt in SE USA, Xyleborus glabratrus, was examined at three sites along a 500 km N-S transect in Florida, each populated by host trees in the Lauraceae. Fungal phenotypes were quantified in mycangia of individual females that were collected from a site...
Fungal mycelia are exposed to heterogenic substrates. The substrate in the central part of the colony has been (partly) degraded, whereas it is still unexplored at the periphery of the mycelium. We here assessed whether substrate heterogeneity is a main determinant of spatial gene expression in colonies of Aspergillus niger. This question was addressed by analyzing whole-genome gene expression ...
Cordyceps militaris has recently been used as a functional food in China and is commonly used as a Traditional Chinese Medicine. The formation of C. militaris fruiting bodies is unstable and is a limiting factor for industrial production. Fruiting body formation and quantities of adenine, adenosine and cordycepin differed significantly between the phenotypes. Orange chrome colonies produced fru...
Nosema ceranae as a fungal parasite has been reported from the Apis mellifera in all continents. It causes reduced longevity, depopulation, decreased production, and colony losses honeybee colonies. This study aimed to determine prevalence of N.ceranae apiaries Mazandaran province. In this study, we randomly selected 320 hives thirty-two collected twenty old honeybees apiaries. The samples were...
