Asymmetry of plant-mediated interactions between specialist aphids and caterpillars on two milkweeds
1. Plant-mediated interactions between co-occurring herbivores play an important role in insect herbivore communities. Although induced resistance pathways associated with jasmonic acid and salicylic acid are often implicated in such plant-mediated interactions, there are few examples from non-model systems involving specialized herbivores that regularly interact in nature. 2. Here, we tested r...
this thesis seeks to present a critical reading of virginia woolf’s mrs. dalloway and michael cunningham’s the hours in terms of an intertextual approach, concentrating on dialogic imagination, negativity, transposition and allusion. this study attempts to evaluate cunninghams perception of woolfs life and work by adopting kristevas conception of intertextuality and her consideration of the hou...
Plants respond to various types of herbivore and pathogen attack using well-developed defensive machinery designed for self-protection. Infestation from phloem-sucking insects such as whitefly and aphid on plant leaves was previously shown to influence both the saprophytic and pathogenic bacterial community in the plant rhizosphere. However, the modulation of the root microbial community by pla...
Recently obtained evidence points to the involvement of the lateral habenular nuclei (LHb) in the mediation of coping defensive responses to threatening/stressful stimuli. Nevertheless, the role of this brain area in the regulation of defensive responses that have been associated with specific subtypes of anxiety disorders recognized in clinical settings is presently unknown. To address this qu...
iv abstract this study examined the linguistic behaviors of two iranian efl teachers each of them teaching learners of two similar proficiency levels, a beginner level and an intermediate level, to investigate the relationship between the learners proficiency levels and the amounts and purposes for l1 use by the two teachers. the study was carried out to investigate whether there were differe...
Fertility, developmental time and adult longevity of walnut aphid, Chromaphis juglandicola (Kalt.) and its parasitoid wasp, Trioxys pallidus (Hal.) were studied under controlled conditions with a constant temperature of 26±2oC, relative humidity of 60±5%, and 16:8 (L:D) photoperiod. Populations of walnut aphid and parasitoid wasp were reared on walnut seedling in a growth chamber. The mean deve...
This study examined developmental change associated with mature kicking by children in grades K-8. We tested children (Grades k-8) on the kicking subtest of the Ohio State University Scale of Intra-Gross Motor Assessment (OSU-SIGMA) 5 times over 9 years. Hierarchical nonlinear modeling was used to analyze the data. The principal findings included: a) significant differences in mean initial stat...
