“…These included subgroups formed based upon scores on the Tallal Repetition test ("low" rep group score 15 and less, "high' rep group score > 15) and another subgrouping based on the syntax scores (low syntax < 3, high syntax 2 3). For all betweensubject ANOVAs the standard parametric model for analysis of unequal n designs was used (Herr, 1986) when necessary. For the auditory recovery cycle data the ERPs were quantified by taking the latency, peak amplitude, and mean area within 50-200, 200-350, and 350-600 msec.…”

Clinical, behavioral, and neurophysiological studies of developmental language impairment (LI), including reading disability (RD), have variously emphasized different factors that may contribute to this disorder. These include abnormal sensory processing within both the auditory and visual modalities and deficits in linguistic skills and in general cognitive abilities. In this study we employed the event-related brain potential (ERP) technique in a series of studies to probe and compare Merent aspects of functioning within the same sample of LI/RD children. Within the group multiple aspects of processing were affected, but heterogeneously across the sample. ERP components linked to processing within the superior temporal gyrus were abnormal in a subset of children that displayed abnormal performance on an auditory temporal discrimination task. An early component of the visual ERP was reduced in amplitude in the group as a whole. The relevance of this effect to current conceptions of substreams within the visual system is discussed. During a sentence processing task abnormal hemispheric specialization was observed in a subset of children who scored poorly on tests of grammar. By contrast the group as a whole displayed abnormally large responses to words requiring contextual integration. The results imply that multiple factors can contribute to the profile of language impairment and that different and specific deficits occur heterogeneously across populations of LI/RD children.

“…Type III ANOVA, which tests for the presence of an effect, given the other effects and the interactions (Herr, 1986), was used to assess the effect of host plant species (grapevine, oak, hornbeam and chestnut), sampling date (May, July, October), edge (habitat centre or edge) and their interactions on foliar OTU richness. Sampling site was included in the model as a random factor.…”

BackgroundDispersal events between habitat patches in a landscape mosaic can structure ecological communities and influence the functioning of agrosystems. Here we investigated whether short-distance dispersal events between vineyard and forest patches shape foliar fungal communities. We hypothesized that these communities homogenize between habitats over the course of the growing season, particularly along habitat edges, because of aerial dispersal of spores.MethodsWe monitored the richness and composition of foliar and airborne fungal communities over the season, along transects perpendicular to edges between vineyard and forest patches, using Illumina sequencing of the Internal Transcribed Spacer 2 (ITS2) region.ResultsIn contrast to our expectation, foliar fungal communities in vineyards and forest patches increasingly differentiate over the growing season, even along habitat edges. Moreover, the richness of foliar fungal communities in grapevine drastically decreased over the growing season, in contrast to that of forest trees. The composition of airborne communities did not differ between habitats. The composition of oak foliar fungal communities change between forest edge and centre.DiscussionThese results suggest that dispersal events between habitat patches are not major drivers of foliar fungal communities at the landscape scale. Selective pressures exerted in each habitat by the host plant, the microclimate and the agricultural practices play a greater role, and might account for the differentiation of foliar fugal communities between habitats.

“…Thus, in a post-hoc analysis this resulted in unbalanced designs. For 2 Â 2 ANOVA design as shown in Table 3c Type III sums of squares (Herr, 1985(Herr, , 1986Langsrud, 2003) were used. Due to the absence of local or global spatial autocorrelation (Anselin, 1995) in the soil samples only a simple ANOVA was performed (Dutilleul, 1993;Legendre et al, 2002).…”
