Six populations of Sinipta dalmani from the provinces of Buenos Aires and Entre Rios (Argentina) were analyzed. The populations of "El Palmar" National Park (Entre Rios) were polymorphic for pericentric inversions in pairs M4 and M7 and for a centric fusion involving pair M5 and the X chromosome. The M4 inversion remained similar over time and the karyomorphic frequencies did not depart from those expected according to the Hardy-Weinberg equilibrium. The analysis of chiasma frequency and… Expand

Phenotypic pattern over centric fusion clinal variation in the water-hyacinth grasshopper, Cornops aquaticum (Orthoptera: Acrididae)
There is a strong inverse correlation of fusion frequency with temperature, which indicates that these polymorphisms may be related to increased tolerance of colder climates in this originally tropical species, or some other correlated variable. Expand
Micro-Evolution in Grasshoppers Mediated by Polymorphic Robertsonian Translocations

It is concluded that Robertsonian polymorphic grasshopper species share some properties with inversion polymorphic species of Drosophila, such as the central-marginal pattern (marginal populations are monomorphic, central populations are highly polymorphic). Expand
Discriminating species of Sinipta Stål (Orthoptera: Acrididae) from Uruguay based on morphological, ethological and molecular data
Two species of the genus Sinipta, S. dalmani and S. hectorisperonii, exist in Uruguay and the combined results suggest that the two studied taxa are distinct species, and point to features suitable for their identification. Expand
Evolution of a supergene that regulates a trans-species social polymorphism
Analysis of whole-genome sequences of males from native populations of six fire ant species shows that variation in social organization is under the control of a novel supergene haplotype (termed Sb), which evolved by sequential incorporation of three inversions spanning half of a ‘social chromosome’.

Chromosome polymorphism in populations of the grasshopper Trimerotropis pallidipennis from southern Argentina
Three populations of the grasshopper Trimerotropis pallidipennis from southern Argentina have been studied cytologically. A very characteristic B-chromosome was found in all three. They also showedExpand
Geographical variability in the pericentric inversion system of the grasshopper Trimerotropis pseudofasciata
It is argued that it is the gene sequence on only the inversion chromosome that is important in Trimerotropis, which contrasts with the “co-adapted” pattern seen in Drosophila where the gene sequences on both chromosomes in the inversions heterozygote are simultaneously important. Expand
Cytogenetic Studies in Sinipta Dalmani Stål (Orthoptera: Acrididae). I. Effects of a Pericentric Inversion on Chiasma Conditions
Two populations of Sinipta dalmani from Entre Rios Province (Argentina) are polymorphic for a pericentric inversion in pair M4, where the inversion precludes the crossing over within its limits in the heterozygous condition and increases terminal chiasma frequency in homozygosis. Expand
Geographic patterns of chromosomal variation in populations of the grasshopper (Trimerotropis pallidipennis) from southern Argentina
A cluster analysis indicated strong chromosomal differentiation between the almost monomorphic populations in the Andes' "precordillera" and the highly polymorphic populations in more eastern locations and showed that chromosome similarity between populations could be predicted by geographic proximity.

Chromosome polymorphisms affecting recombination and exophenotypic traits in Leptysma argentina (Orthoptera): a populational survey
The frequencies of the fusion, segment Si and the B-chromosome follow a geographical pattern, and no significant effects were detected for segments but Si is geographically widespread, arguing against its neutrality, while the low frequency and even frequency distribution of Sp suggests maintenance by mutation.

Effects of chromosome rearrangements on sperm formation in Sinipta dalmani (Orthoptera: Acrididae)
The DNA content of giant spermatids was mainly 2c, suggesting that there may be any meiotic misbehaviour during meiosis, and other mechanism, such as cell fusion, may be involved in the production of abnormal sperm. Expand

The results indicate that the polymorphic mutation has an effect on intrachromosomal recombination, which would have adaptive significance, in contrast with the situation of spontaneous fusion which rarely persists in the population. Expand
Effects of centric-shift polymorphisms on chiasma conditions inTrimerotropis pallidipennis (Oedipodinae:Acrididae)
Two populations ofTrimerotropis pallidipennis from Mendoza and Uspallata (UA) (Argentina), polymorphic with respect to centric shifts and B-chromosomes, were cytologically analysed and showed a clear tendency towards chiasma localisation and a redistribution of chiasmata, which could increase genetic recombination.

Effects of centric fusions on chiasma frequency and position in Leptysma argentina (Acrididae: Orthoptera) I. Spontaneous and stable polymorphic centric fusions
The results suggest that proximal and interstitial chiasma reduction observed in trivalent 3-3/6-6 of L. argentina is due to a later adaptation to the polymorphic condition or a fortuitous genetic condition present in the original mutant, rather than to a direct effect of the fusion itself on chiasMA distribution.

Inter-population sex chromosome polymorphism in the grasshopper Podisma pedestris
The montane grasshopper Podisma pedestris exists in Europe in two chromosomally distinct kinds of population. One has an XO/XX sex chromosome mechanism and a diploid chromosome number of 23 male, 24Expand
