Sex chromosomes have evolved independently many times across eukaryotes. Despite a
considerable body of literature on sex chromosome evolution, the causes and …

Sex chromosomes have evolved many times from morphologically identical autosome pairs,
most often presenting several recombination suppression events, followed by accumulation …

Abstract The American dragonfly genus Orthemis Hagen, 1861 is mainly found in the
Neotropical region. Seven of 28 taxonomically described species have been reported from …

Background Neo-sex chromosome systems arose independently multiple times in evolution,

In an attempt to track the chromosomal differentiation in the Dichroplus elongatus species
group, we analyzed the karyotypes of four species with classical cytogenetic and mapping …

South American melanopline grasshoppers display a disproportionate number of derived
karyotypes, including many cases of neo-sex chromosome systems. This is especially true of …

Orthopterans are a fascinating group of insects in multiple ways. My own research focuses
on the evolutionary relationships of South American acridoid grasshoppers with emphasis in …
