Multivariate analysis of morphometry effect on race performance in Thoroughbred horses
(Brazilian Journal of Animal Science, 2023)
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 ...
Application of morphometric measures in estimation of body weight and discrimination of Astyanax lacustris and Astyanax fasciatus
(2019-01-01)
The objective of this study was to verify the direct and indirect correlation between morphometric measures, ratios, body weight and yield in two lambari species Astyanax lacustris and Astyanax fasciatus and whether the ...
Testing repeatability, measurement error and species differentiation when using geometric morphometrics on complex shapes: a case study of Patagonian lizards of the genus Liolaemus (Squamata: Liolaemini)
(Wiley Blackwell Publishing, Inc, 2020-07-14)
The repeatability of findings is the key factor behind scientific reliability, and the failure to reproduce scientificfindings has been termed the "replication crisis". Geometric morphometrics is an established tool in ...
Geographic variation of Africanized honey bees (Apis mellifera L.) in Brazil: Multivariate morphometrics and racial admixture
(1996-06-01)
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 ...

(1996-06-01)
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 ...
Total length estimation of the Brazilian flathead Percophis brasiliensis, using morphometric relationships of skull, pectoral girdle bones, otoliths and specific body measures, in Argentine waters
(Wiley Blackwell Publishing, Inc, 2013-03)
Predictive regression equations were generated to estimate total length of the Brazilian flathead (Percophis brasiliensis) fish using skull and pectoral girdle bones as well as specific body and otolith lengths. All ...
Evaluation of Lingual Frenulum Using Geometric Morphometrics
(Sociedad Chilena de Anatomía, 2011)
Genetic and morphometric differentiation between island and mainland southern elephant seal populations
(The Royal Society, 2001-02)
We compare genetic (both nuclear and mitochondrial) and morphometric measures between two putative populations of southern elephant seal (Mirounga leonina), and interpret the results in the context of data from mark-recapture ...
