Shell-shape variation along the latitudinal range of the Chilean blue mussel Mytilus chilensis (Hupe 1854)
(Blackwell Publishing Ltd, 2007)
Shell-shape variation in the Chilean blue mussel
Mytilus chilensis was examined in eight populations
covering the totality of its distribution range,
which represents over 1800 km of latitudinal gradient
in the ...
Distribution related to temperature and salinity of the shrimps Acetes americanus and Peisos petrunkevitchi (Crustacea: Sergestoidea) in the south-eastern Brazilian littoral zone
(2013-05-01)
The abundance and ecological distribution of Acetes americanus and Peisos petrunkevitchi were investigated from July 2006 to June 2007, in Ubatuba, Brazil. Eight transects were identified and sampled monthly: six of these ...

A survey of shape variation in keratinized labial teeth of anuran larvae as related to phylogeny and ecology
(Oxford University Press, 2010-11)
Labial teeth of anuran tadpoles are keratinized structures derived from the activity of a single epidermal cell of the oral labia; they are not homologous with adult anuran teeth, nor with teeth of other vertebrates. The ...
Canonical discriminant analysis applied to broiler chicken performance
(CAMBRIDGE UNIV PRESS, 2008)
The mechanisms involved in the control of growth in chickens are too complex to be explained only under univariate analysis because all related traits are biologically correlated. Therefore, we evaluated broiler chicken ...

(BioMed Central, 2017)
Abstract
Background
Culex nigripalpus has a wide geographical distribution and is found in North and South America. Females are considered ...
Description of two new species closely related to Doryctobracon areolatus (Szépligeti, 1911) (Hymenoptera, Braconidae), based on morphometric and molecular analyses
(Magnolia Press, 2017-11)
This study clarifies the identity of two morphs that appear similar but not identical to the braconid wasp Doryctobracon areolatus (Szépligeti), by analyses of fore wing morphometry and the ITS2 and D2 region of 28S ribosomal ...
Geographic polymorphism of P element in populations of Drosophila sturtevanti
(Sociedade Brasileira de Genética, 2003-01-01)
The aim of this report was to detect full-sized P element sequences in eight strains of Drosophila sturtevanti populations from distant geographic regions and to assess the structural geographic variation among P element ...
