The relative palatabilities of seven species of heliconiine butterflies from Trinidad studied by Brower, Brower, and Collins (1963) correlate with variables directly related to individual dispersal and presumably inbreeding. The more unpalatable a species, the greater the number of geographic races and the higher the probability that populations will form site-specific roosting aggregations indicative of home-range behavior and inbreeding. These correlations are expected if kin selection has… 

Geographical patterns of evolution in Neotropical Lepidoptera. Systematics and derivation of known and new Heliconiini (Nymphalidae: Nymphalinae)

Analysis of the known and recently discovered differentiation patterns of 58 forest butterfly species in the tribe Heliconiini, including over 300 races and forms, has led to the drawing of a map of core areas for evolution in the group, which indicates a larger number of significant operative refugia than other analyses.

Adaptive radiation and convergence in subdivisions of the butterfly genus Heliconius (Lepidoptera: Nymphalidae)

The process of adaptive radiation and convergence, usually regarded as a feature of macro-evolution, can be seen in the mimetic colour patterns of the butterflies within the confines of the South American genus Heliconius, and the theory that the mimicry between species results solely from close systematic relationships is refuted.

Radiation of the polymorphic Little Devil poison frog (Oophaga sylvatica) in Ecuador

The phylogeographic pattern among color‐divergent populations of the Little Devil poison frog Oophaga sylvatica is explored by analyzing population structure and genetic differentiation to evaluate which processes could account for color diversity within and among populations.

Higher level phylogeny for the passion‐vine butterflies (Nymphalidae, Heliconiinae) based on early stage and adult morphology

A higher level phylogeny for the passion-vine butterflies (Nymphalidae, Heliconiinae) was generated by cladistic analysis of 146 morphological characters from all life stages, and supported the monophyly of all currently recognized genera.

Genetic structure of natural populations ofDryas iulia (Lepidoptera: Nymphalidae) revealed by enzyme polymorphism and mitochondrial DNA (mtDNA) restriction fragment length polymorphism (RFLP)

Analyzing six samples from Southern Brazil in relation to three enzyme systems and their mtDNA RFLP patterns, it is found that they are very similar at the molecular level, and it is concluded that all localities belong to the same population.

The ecology and social behaviour of the Neotropical butterfly Heliconius xanthocles Bates in Colombia

The mimicry, population ecology1, adult behaviour and life cycle of Heliconius xanthocles were studied at two sites in Colombian tropical forest. The results were compared with the known biology of

Unpalatability in anuran larvae as a defense against natural salamander predators

In the laboratory, natural salamanders are used as predators to investigate relative payabilities of the larvae of three species of anurans that differ in their mode of aggregation, finding that unpalatability may be one means by which larvae in conspicuous groups avoid predation.

Evolutionary patterns in chromosome numbers in neotropical Lepidoptera. I. Chromosomes of the Heliconiini (family Nymphalidae: subfamily Nymphalinae).

Chromosome counts in meiotic metaphase plates in the gonads of 67 of the probable 68 species of mimetic neotropical heliconian butterflies (Nymphalidae) revealed a consistent haploid number of n = 21, while deficient pairing was seen in intersubspecific hybrids in Eueides tales and Heliconius sara.

Dispersal and gene flow in a butterfly with home range behavior: Heliconius erato (Lepidoptera: Nymphalidae)

Genetic and dispersal data together show that kin selection is an unlikely mechanism for the evolution of warning color and other supposed altruisms in Heliconius, unless occasional genetic drift is also involved.
