Phylogenetic factorization of compositional data yields lineage-level associations in microbiome datasets
Alex D. Washburne,Justin D. Silverman,Jonathan W. Leff,Dominic J. Bennett,John L. Darcy,Sayan Mukherjee,Noah Fierer,Lawrence A. David +7 more
TL;DR: This work uses the method, “phyl ofactorization,” to re-analyze datasets from the human body and soil microbial communities, demonstrating how phylofactorization is a dimensionality-reducing tool, an ordination-visualization tool, and an inferential tool for identifying edges in the phylogeny along which putative functional ecological traits may have arisen.

Multivariate Fractional Regression Estimation of Econometric Share Models
TL;DR: The paper discusses the stochastic aspects of share definition and measurement, and summarizes important features of the existing literature on econometric strategies for share model estimation, and proposes an extended fractional regression methodology proposed by Papke and Wooldridge.
Journal ArticleDOI
Effective use and interpretation of lithogeochemical data in regional mineral exploration programs: application of Geographic Information Systems (GIS) technology☆
TL;DR: In this paper, the authors used a Geographic Information System (GIS) in concert with statistical and geostatistical software to compile, manipulate, analyze and visualize a large lithogeochemical dataset collected from the Archean age Swayze greenstone belt (SGB) located in northern Ontario, Canada.

Linking abundances of the dung fungus Sporormiella to the density of bison: implications for assessing grazing by megaherbivores in palaeorecords
Jacquelyn L. Gill,Kendra K. McLauchlan,Adam M. Skibbe,Simon Goring,Chad R. Zirbel,Chad R. Zirbel,John W. Williams +6 more
TL;DR: The use of Sporormiella is refined as a proxy for local megaherbivore presence, especially in grassland systems to help elucidate the past drivers of grassland dynamics, including the possible role of bison in mediating grass–forb interactions during the variable moisture regimes of the last 12,000 years.
Journal ArticleDOI
Positive genetic correlation between female preference and offspring fitness
TL;DR: It is shown that females of Drosophila serrata prefer extreme male cuticular hydrocarbon (CHC) blends, and that this preference affects offspring fitness, indicating that females have gained genetic benefits from their choice of males.

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.
