Última Elytra colour polymorphism and randomness of matings in Chauliognathus fallax Germar 1824 from southern Brazil (Coleoptera, Cantharidae) Rev. Bras. entomol. Machado,Vilmar; Araújo,Aldo Mellender de. Beetles of the species Chauliognathus fallax Germar 1824 are polymorphic for elytron colouration with six morphs distinguished on the basis of black pigmentation on a yellow background. We investigated samples of C. fallax taken in eight consecutive weeks aiming to determine the frequency of the morphs which were grouped, for statistical analysis, into three classes according to elytra pigmentation as well as the possible occurrence of assortative mating. Our results showed a variation in the frequency of the classes throughout the season, both in males and females, with the maximum frequency of each class at the fourth and fifth week. The three classes (A, B, C) showed the same pattern of variation, and class B was always the more frequent. To test...

Bras. Zool. Dias,Tailise M.; Prado,Cynthia P.A.; Bastos,Rogério P.. ABSTRACT Anuran males and females adopt different reproductive and behavioral strategies in different contexts. We investigated the reproductive ecology and territorial behavior of the treefrog Boana goiana (B. Lutz, 1968) from the Brazilian Cerrado. We hypothesized that competitor density/proximity would increase the behavioral responses of B. goiana males, and that mating would be assortative. We also tested if the number of eggs correlates with female size and if there is a trade-off between clutch size and egg size. We conducted two territoriality experiments to test the effects of male size, competitor proximity and competitor density. Larger males called more in the presence of a second male. In the second experiment, the largest males emitted more...

Ano: 2021 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1984-46702021000100307 Color polymorphism in Chauliognathus flavipes Fabricius (Coleoptera, Cantharidae): II. Patterns of emergence of morphs and mating system Zoologia Machado,Vilmar; Araújo,Aldo Mellender de. This study presents data on the color polymorphism in Chauliognathus flavipes Fabricius 1781 (Coleoptera, Cantharidae), analysing the variations in the emergence pattern of phenotypic classes for elytra color and mating system. The frequency of the phenotypic classes varies significantly throughout the season (males:X² = 59,705; females: X² = 61,017; 10 gl; p<0.001) being similar in males and females. The frequency of classes does not differ significantly among the insects that were copulating and those that were not copulating at the time of collection, i.e., the matings are random for elytra color patterns. The variations observed in frequency of phenotypic classes are not influenced by factors associated with sex. Furthermore, the elytra color...
