The CAT-SIR is out of the bag: tumors prefer host rather than dietary nutrients

The extent to which tumors acquire nutrients from dietary sources as opposed to from the breakdown of host tissues is not known. In this issue of BMC Biology, Holland et al. report an approach where food sources with different isotope labeled carbon ratios can be used to answer this question, and find that tumors arising in Drosophila melanogaster procure most of their nutrients from the host.

Genotypes of the Cacoecia Podana Sc. Larvae in the Aes-1 Esterase Locus Differ in Their Food Micro-Niches

Intergenotypic differentiation of trophic niche was studied in the system “apricot (Prunus armeniaca L.) - Cacoecia podana Sc.”. C. podana larvae, carried alternative Aes-1 genotypes, were found to prefer host plant leaves, differing by length and stiffness, in their diets. Trophic micro-niches for each genotype coincided with the whole population niche in width, but differed by their optimums. There data are discussed in respect to the herbivore food specialization and population dynamics.

Consumer Acculturation and Implications for Brand Preferences

This research investigates whether established theories of acculturation are applicable to British Indians and what impact acculturation has on their consumer behaviour. After classifying British Indians according to the acculturation framework devised by Berry (1980), the chapter considers whether membership of these acculturation categories has a bearing on British Indians' consumer behaviour, as indicated by their brand preferences for a range of host and ethnic products and services. The findings reveal that separated consumers prefer ethnic brands more than host brands, assimilated consumers prefer host brands more than ethnic brands and integrated consumers have brand preferences falling between these two. Acculturation category thus has POTENTIAL for use as a segmentation variable. Demographic factors have also been shown to influence patterns of acculturation (Berry 1997). This study therefore also examines the relationships between different acculturation categories, demographic variables and preferences for a range of ethnic and host brands. Overall, this research provides some interesting insights about buying preferences of Indian diaspora (a developing country) in the UK and is particularly relevant from an International marketing perspective.
