Herbivory by a phloem-feeding insect inhibits floral volatile production
Martín Pareja,Erika Qvarfordt,Ben Webster,Patrick Mayon,John A. Pickett,Michael A. Birkett,Robert Glinwood +6 more
TL;DR: It is shown that herbivory by phloem-feeding aphids inhibits floral volatile emission in white mustard Sinapis alba measured by gas chromatographic analysis of headspace volatiles, and that the outcome of interaction between Herbivory and floral chemistry may differ depending on the herbivore's feeding mode and degree of specialisation.

Does sward height affect feeding patch choice and voluntary intake in horses
Nadège Edouard,Nadège Edouard,Géraldine Fleurance,Géraldine Fleurance,Bertrand Dumont,René Baumont,Patrick Duncan +6 more
TL;DR: The results show that horses choose between vegetative patches of a good and similar quality according to the predictions from optimal foraging models, and select the one that they can ingest faster.

The resolution of a compositional data set into mixtures of fixed source compositions
TL;DR: In this article, a compositional data set X (n x p) consisting of the measurements on p variables for each of n specimens, but without any prior knowledge on the formation of X, is presented.
Journal ArticleDOI
Compositional data analysis of some alkaline glasses
TL;DR: In the context of exploratory methods of multivariate analysis, such as principal component analysis (PCA) as mentioned in this paper, traditional methods can produce more interpretable results than the log-ratio approach, since traditional methods often detect certain kinds of structure in the data that correspond to structure on a ratio scale.
Journal ArticleDOI
Forest fragmentation is associated with primary brood sex ratio in the treecreeper (Certhia familiaris).
TL;DR: Evidence that male nestlings were more costly to produce, since they suffered twofold higher nestling mortality and were larger in body size than females is found, and habitat quality as measured by habitat characteristics is associated with sex allocation in free–living birds.

Problems of relative growth
TL;DR: This detailed study of the different rates of growth of parts of the body relative to the body as a whole represents Sir Julian Huxley's great contribution to analytical morphology, and it is still a basis for modern investigations in morphometrics and evolutionary biology.

Experiments with Mixtures: Designs, Models and the Analysis of Mixture Data
TL;DR: In this paper, the original Mixture Problem is described and models for exploring the Entire Simplex Factor Space are presented, including matrix algebra, least squares, and the analysis of variance.
New statistical methods for allometry with application to
TL;DR: In this paper, Mosimann et al. presented new statistical methods for the study of size and shape, and used these methods to study the morphology of red-winged blackbirds, Agelaius phoeniceus breeding in Florida.

Analysis of dispersion on a sphere
TL;DR: In this article, a series of approximate tests of significance is given for hypotheses about the precision constant K and the polar vector on a sphere, where 8' is the angle between the polar and observation vectors.
