The capability to fight against them is of great advantage, but may also be traded off with other traits. Although often observed at the phenotypic level, our knowledge of the extent to which such trade-offs are genetically determined is relatively poor. We tested this possibility with a farmed rainbow trout population suffering from natural Diplostomum spp. infections that cause cataracts in fish. We estimated the heritability of cataract severity and examined phenotypic and genetic correlations between cataract and a set of performance traits measured three times during a 3-year rearing period. A cataract score was used as an indicator of the host's capability to resist and/or tolerate the parasite. Our results showed moderate heritability for the cataract. Nevertheless, we found no evidence for a genetic or phenotypic trade-off between parasite resistance/tolerance and the measured performance traits. Initial body weight was not correlated with the cataract score. Phenotypic and genetic correlations of cataract severity with body mass and condition measured in the second and third year were strongly negative, indicating reduced growth and condition in fish with a high cataract score. The reduced body size and condition in cataract-bearing fish were probably reflected in the phenotypic association between a high cataract score and delayed maturity age in females. Put together, our study did not provide evidence of genetic or phenotypic trade-offs between Diplostomum resistance/tolerance and a number of performance traits. Therefore, selection for lessened Diplostomum-caused cataracts is unlikely to have a negative impact on the studied performance traits.第三个:也是2009年的Cataract Symptom Scale: Clarifying measurementAbstractAim: Previous psychometric evaluation of the Cataract Symptom Scale (CSS) focused on classic assessments of reliability and validity. Our aim was to investigate the psychometric properties of the CSS using the Rasch measurement : 243 patients drawn from the Flinders Eye Centre cataract surgery waiting list self-administered the CSS. Rasch analysis was used to investigate the following properties of the CSS: measurement a single construct (unidimensionality), discrimination between strata of patient ability (person separation) and targeting of item difficulty to person : The CSS discriminated four strata of patients. However, some items did not contribute towards measurement of a single construct indicating a secondary dimension. This comprised three mobility items, which formed a separate valid subscale. Elimination of these items resulted in the CSS being a unidimensional measure. However, further item deletion was required as some more items did not appear to measure the same construct. The resultant 9-item measure was : The CSS consists of two separate unidimensional constructs: mobility and visual disability. The reduced 9-item measure has good psychometric properties and is unidimensional. The CSS is essentially a measure of visual disability and not cataract symptoms as it is claimed to be.如果觉得不够,我再找
