A chemical level in the coevolutionary arms race between an ant social parasite and its hosts.
TL;DR: It is shown that in behavioural aggression trials, host colonies could indeed discriminate between invading slaves, which commonly accompany slavemakers on raids, and free‐living conspecifics, presumably to reduce the costs of defence.
Journal ArticleDOI
Interactions between two aphid natural enemies, the entomopathogenic fungus Erynia neoaphidis Remaudiere & Hennebert (Zygomycetes: Entomophthorales) and the predatory beetle Coccinella septempunctata L. (Coleoptera: Coccinellidae)
TL;DR: Ladybird foraging on E. neoaphidis -infected aphids and their ability to vector infective conidia to susceptible aphid populations is discussed in relation to the epizootiology of the fungus and its implications for the manipulation of natural enemies in integrated management strategies.
Journal ArticleDOI
Modelling the joint variability of grain size and chemical composition in sediments
M.R. Bloemsma,Matthias Zabel,Jan-Berend W Stuut,Rik Tjallingii,James A Collins,Gert Jan Weltje +5 more
TL;DR: In this paper, a mathematical method was proposed to decompose the total geochemical variability of a series of genetically related specimens into a grain-size dependent (the shared signal) and a grain size independent part (the residual signal).
Journal ArticleDOI
Compositional Kriging: A Spatial Interpolation Method for Compositional Data
TL;DR: In this paper, compositional kriging is introduced as a straightforward extension of ordinary Kriging that complies with the constant sum and non-negativity constraints of compositional data.
Journal ArticleDOI
Home range size and daytime habitat selection of leopards in Huai Kha Khaeng Wildlife Sanctuary, Thailand
TL;DR: In this paper, the authors used radio telemetry to investigate seasonal variation in habitat selection and home range size of leopards in Huai Kha Khaeng Wildlife Sanctuary, Thailand.

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.
