Process recognition in multi-element soil and stream-sediment geochemical data
TL;DR: In this article, the effects of groundwater on element concentrations are more evident in soils than stream sediments, and a "winnowing index" was created using ratios of Th to Al that revealed differing erosional and depositional environments.

TL;DR: This work reports the development of a transcriptional profiling approach to determine age of adult female Aedes aegypti under field conditions that surpasses current cuticular hydrocarbon methods for both accuracy of predicted age as well as the upper limits at which age can be reliably predicted.
Journal ArticleDOI
Implications of Predator Foraging on Aphid Pathogen Dynamics
TL;DR: Although no sporulating infected aphids were completely consumed, both adult and larval ladybirds can still be considered as intraguild predators and the presence of a foraging adult ladybird resulted in a significant increase in transmission of the fungus to healthy aphids.
Journal ArticleDOI
Fingerprinting historical fluvial sediment fluxes
TL;DR: In this article, an overview is provided of the tracer properties that can be used to distinguish between the various sediment sources in a river catchment. From this general compilation, those tracers useful to fingerprint fine-grained floodplain deposits on a historical timescale (decadal to millennial).
Journal ArticleDOI
Understanding perturbation on the simplex: A simple method to better visualize and interpret compositional data in ternary diagrams
TL;DR: Perturbation is an operation defined on the simplex and can be used for centering compositional data in a ternary diagram, applying objective criteria as mentioned in this paper, which is illustrated by some examples using simulated as well as real data.

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.
Journal ArticleDOI
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.
