Rensch’s Rule in Dichroplus pratensis: A Reply to Wolak
(Oxford University Press, 2019)
B chromosomes and Robertsonian fusions of Dichroplus pratensis (Acrididae): intraspecific support for the centromeric drive theory
(Karger, 2004-12)
We tested the centromeric drive theory of karyotypic evolution in the grasshopper Dichroplus pratensis, which is simultaneously polymorphic for eight Robertsonian fusions and two classes of B chromosomes. A logistic ...
Rensch’s Rule in Dichroplus pratensis: A Reply to Wolak
(Oxford University Press, 2008)
Geographic and climatic factors related to a body-size cline in Dichroplus pratensis Bruner, 1900 (Acrididae, Melanoplinae)
(Orthopterists' Society, 2008-12)
We studied geographic body size variation in males and females of 25 populations of the South American melanopline grasshopper Dichroplus pratensis Bruner, 1900, along more than 22 degrees of latitude (S) and between 0 and ...
FISH detection of ribosomal cistrons and assortment-distortion for X and B chromosomes in Dichroplus pratensis (Acrididae)
(Karger, 2004-12)
Assortment-distortion with respect to the X and NOR activity of a rare mitotically stable B chromosome (BN), was examined in 16 males of Dichroplus pratensis (Acrididae: Melanoplinae) from Argentine populations. In 1B ...
Variability along a latitudinal gradient in the chiasma frequency and morphological characters of Dichroplus pratensis (Orthoptera: Acrididae)
(Czech Academy of Science, 2005-03)
The grasshopper Dichroplus pratensis Bruner is polymorphic and polytypic for a complex Robertsonian system. In this species, centric fusions induce changes in number and position of chiasmata, and thus potentially affect ...
A test of Allen’s rule in ectotherms: the case of two south American melanopline grasshoppers (orthoptera: acrididae) with partially overlapping geographic rangesUn test de la regla de Allen en ectotermos: el caso de dos saltamontes melanoplinos (orthoptera: acrididae) sudamericanos con distribuciones geográficas parcialmente solapadas
(Sociedade Entomológica do Brasil, 2008-12)
We studied the geographic variation of three morphometric characters in relation to body size in two South American grasshoppers (Acrididae), Dichroplus vittatus Bruner and D. pratensis Bruner to test Allen’s rule in these ...
The central-marginal hypothesis in acridid Orthoptera: a critique of Colombo's (2012) article
(Czech Academy of Sciences, 2013-02)
We discuss and criticise the contention of Colombo (2012) that the central-marginal model does not apply to three species of chromosomally polymorphic acridid grasshoppers, and that chromosomal clines in these species are ...
