Multivariate morphometrics and allometry and allometry in a polymorphic ant
(Birkhauser Verlag Ag, 1994-01-01)
In this paper we describe how morphological castes can be distinguished using multivariate statistical methods combined with jackknife estimators of the allometric coefficients. Data from the polymorphic ant, Camponotus ...
Geographic variation of Africanized honey bees (Apis mellifera L.) in Brazil: Multivariate morphometrics and racial admixture
The correspondence between morphometric and isozymic geographic variation patterns of Africanized honey bees in Brazil was analyzed. Morphometric data consisted of mean vectors of 19 wing traits measured in 42 local ...
MULTIVARIATE MORPHOMETRIC ANALYSIS OF SELECTED PROISOTOMA SPECIES (COLLEMBOLA, ISOTOMIDAE)
(Gustav Fischer VerlagJenaAlemanha, 1991)
Landmark-based morphometric analysis in selected species of serranid fishes (Perciformes : Teleostei)
(Acad Sinica Inst Zoology, 1999-07-01)
Morphological differences among 6 species of marine fishes belonging to 2 subfamilies of the family Serranidae (Serraninae: Dules auriga, Diplectrum formosum, and D, radiale; Epinephelinae: Epinephelus marginatus, Mycteroperca ...
Evolution and population structure of africanized honey bees in Brazil: Evidence from spatial analysis of morphometric data
(Soc Study Evolution, 1995-12-01)
In recent years, studies based on isoenzymatic patterns of geographic variation have revealed that what is usually called the Africanized honey bee does not constitute a single population. Instead, several local populations ...
GEOGRAPHIC-VARIATION IN APIS-CERANA-INDICA F - A SPATIAL AUTOCORRELATION ANALYSIS OF MORPHOMETRIC PATTERNS
(Int Bee Research Assoc, 1993-01-01)
Spatial patterns of morphometric variation in Apis cerana indica were analysed. Factor and spatial autocorrelation analyses were applied to 29 characters, measured in 17 populations in India. Correlograms showed that 15 ...
