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 ...
Grassland connectivity explains entomophilous plant species assemblages in an agricultural landscape of the Pampa Region, Argentina
(Wiley Blackwell Publishing, Inc, 2017-06)
The Pampa grassland of Argentina is one of the most highly threatened biomes in the world. A high proportion of the original grassland cover has been transformed into land for agriculture or degraded. In the southern part ...

Is xenodontine snake reproduction shaped by ancestry, more than by ecology?
(Wiley, 2017-01)
One of the current challenges of evolutionary ecology is to understand the effects of phylogenetic history (PH) and/or ecological factors (EF) on the life-history traits of the species. Here, the effects of environment and ...
Analytical attitude propagation with non-singular variables and gravity gradient torque for spin stabilized satellite
(Elsevier B.V., 2007-01-01)
An analytical approach for the spin stabilized satellite attitude propagation is presented using the non-singular canonical variables to describe the rotational motion. Two sets of variables were introduced for Fukushima ...

Phenotypic variation of south-western Atlantic clam Mactra isabelleana (Bivalvia: Mactridae)
(Cambridge University Press, 2012)
The phenotypic shell shape variation of Mactra isabelleana was tested using the geometric morphometric method. Four localities were sampled along the Río de la Plata estuary and the coast of Buenos Aires province. Principal ...
