Spreading of heterochromatin and karyotype differentiation in two Tropidacris Scudder, 1869 species (Orthoptera, Romaleidae)
Although the chromosome number and morphology are conserved in the genus, Tropidacris cristata grandis substantially differs from Tropid ACris collaris in terms of the distribution of repetitive sequences, which could contribute to speciation within the genus. Expand
Chromosome mapping in Abracris flavolineata (De Geer, 1773) (Orthoptera) from the Iguaçu National Park – Foz do Iguaçu, Paraná, Brazil
The results added to the existing cytogenetic studies provided evidence of great karyotypic plasticity in the species, which may be the result of vicariant events related to the geographical distribution of different populations of A. flavolineata. Expand
Evolutionary Dynamics of Tropisternus Karyotype (Coleoptera: Hydrophilidae: Hydrophilini) from Southern Brazil
This paper analyzes seventeen specimens of Tropisternus mutatus sapucay Fernández & Bachman from rivers from two localities in Southern Brazil and discusses the basal number and the possible divergence among the different Hydrophilidae species analyzed to date. Expand
Cytomolecular analysis of the male sex chromosome of Tropidacris cristata grandis (Thunberg, 1824) (Orthoptera: Romaleidae)
Based on the hybridization pattern, it is possible that the autosomes and sex chromosomes of T. c. Expand
