Are there evidences of a complex mimicry system among Asclepias curassavica (Apocynaceae), Epidendrum fulgens (Orchidaceae), and Lantana camara (Verbenaceae) in Southern Brazil?
The goal of this paper was to test the presence of mimicry in Asclepias curassavica L., Epidendrum fulgens Brong., and Lantana camara L. The study was carried out at the Parque Estadual de Itapeva,Expand

Kin recognition in immatures of Heliconius erato phyllis (Lepidoptera; Nymphalidae)
Females of the neotropical butterfly Heliconius erato phyllis lay eggs individually, which, after hatching into caterpillars, can be cannibalistic towards neighboring eggs. Laboratory experimentsExpand

It is a matter of taste: chemical signals mediate nuptial gift acceptance in a neotropical spider
Nuptial gift offering is a courtship trait found among several insect orders and some spider families. Recent studies indicate that this gift-giving behavior in spiders represents the male matingExpand

Spreading the evolutionary synthesis: Theodosius Dobzhansky and genetics in Brazil
The so-called Evolutionary Synthesis, the present paradigm for evolutionary explanations, was established during the 1920s, 1930s and 1940s. One of the leading scientists contributing to this wasExpand

Analysis of the mating behavior and some possible causes of male copulatory success in Dryas iulia alcionea (Lepidoptera, Nymphalidae, Heliconiinae)
In this study we examined the mating behavior of Dryas iulia and the acceptance and rejection mechanisms of females during courtship activity. An ethogram of mating behavior was organized on theExpand

The relationship between altitude and cyanogenesis in white clover (Trifolium repens, L.)
SUMMARYA total of 694 plants of Trifolium repens were collected in 17 samples to investigate the effect of altitude on the frequency of cyanogenic plants; the area chosen for this purpose was NorthExpand

Courtship behavior of Heliconius erato phyllis (Lepidoptera, Nymphalidae) towards virgin and mated females: conflict between attraction and repulsion signals?
Previous observations of Heliconius erato phyllis females being intensively courted a few days after mating contradict the proposal of sexual repulsion caused by a male-transferred antiaphrodisiac.Expand

Phylogenetic relationships and the evolution of mimicry in the Chauliognathus yellow-black species complex (Coleoptera: Cantharidae) inferred from mitochondrial COI sequences
The phylogenetic relationships of twelve species of Chauliognathus were investigated by studying the mitochondrial cytochrome oxidase I gene. A 678 bp fragment of the COI gene was sequenced to testExpand
