Alfred Russel Wallace and the Darwinian Species Concept
Gayana 73(2): Suplemento, 2009 ISSN 0717-652X ALFRED RUSSEL WALLACE AND THE Darwinian SPECIES CONCEPT: HIS paper ON THE swallowtail BUTTERFLIES (PAPILIONIDAE) OF 1865 ALFRED RUSSEL WALLACE Y EL concepto darwiniano DE ESPECIE: SU TRABAJO DE 1865 SOBRE MARIPOSAS papilio (PAPILIONIDAE) Jam ES MA LLET 1 Galton Laboratory, Department of Biology, University College London, 4 Stephenson Way, London UK, NW1 2HE E-mail: [email protected] Abstract Soon after his return from the Malay Archipelago, Alfred Russel Wallace published one of his most significant papers. The paper used butterflies of the family Papilionidae as a model system for testing evolutionary hypotheses, and included a revision of the Papilionidae of the region, as well as the description of some 20 new species. Wallace argued that the Papilionidae were the most advanced butterflies, against some of his colleagues such as Bates and Trimen who had claimed that the Nymphalidae were more advanced because of their possession of vestigial forelegs. In a very important section, Wallace laid out what is perhaps the clearest Darwinist definition of the differences between species, geographic subspecies, and local ‘varieties.’ He also discussed the relationship of these taxonomic categories to what is now termed ‘reproductive isolation.’ While accepting reproductive isolation as a cause of species, he rejected it as a definition. Instead, species were recognized as forms that overlap spatially and lack intermediates. However, this morphological distinctness argument breaks down for discrete polymorphisms, and Wallace clearly emphasised the conspecificity of non-mimetic males and female Batesian mimetic morphs in Papilio polytes, and also in P. -

Patel1,2,6,* ABSTRACT INTRODUCTION The wings of butterflies and moths (Lepidoptera) are typically covered The wings of butterflies and moths (Lepidoptera) have inspired with thousands of flat, overlapping scales that endow the wings with studies across a variety of scientific fields, including evolutionary colorful patterns. Yet, numerous species of Lepidoptera have evolved biology, ecology and biophysics (Beldade and Brakefield, 2002; highly transparent wings, which often possess scales of altered Prum et al., 2006; Gilbert and Singer, 1975). Lepidopteran wings morphology and reduced size, and the presence of membrane are generally covered with rows of flat, partially overlapping surface nanostructures that dramatically reduce reflection. Optical scales that endow the wings with colorful patterns. Adult scales are properties and anti-reflective nanostructures have been characterized chitin-covered projections that serve as the unit of color for the wing. for several ‘clearwing’ Lepidoptera, but the developmental processes Each scale can generate color through pigmentation via molecules underlying wing transparency are unknown. Here, we applied that selectively absorb certain wavelengths of light, structural confocal and electron microscopy to create a developmental time coloration, which results from light interacting with the physical series in the glasswing butterfly, Greta oto, comparing transparent nanoarchitecture of the scale; or a combination of both pigmentary and non-transparent wing regions. -

Mimicry - Ecology - Oxford Bibliographies 12/13/12 7:29 PM Mimicry David W. Kikuchi, David W. Pfennig Introduction Among nature’s most exquisite adaptations are examples in which natural selection has favored a species (the mimic) to resemble a second, often unrelated species (the model) because it confuses a third species (the receiver). For example, the individual members of a nontoxic species that happen to resemble a toxic species may dupe any predators by behaving as if they are also dangerous and should therefore be avoided. In this way, adaptive resemblances can evolve via natural selection. When this phenomenon—dubbed “mimicry”—was first outlined by Henry Walter Bates in the middle of the 19th century, its intuitive appeal was so great that Charles Darwin immediately seized upon it as one of the finest examples of evolution by means of natural selection. Even today, mimicry is often used as a prime example in textbooks and in the popular press as a superlative example of natural selection’s efficacy. Moreover, mimicry remains an active area of research, and studies of mimicry have helped illuminate such diverse topics as how novel, complex traits arise; how new species form; and how animals make complex decisions. General Overviews Since Henry Walter Bates first published his theories of mimicry in 1862 (see Bates 1862, cited under Historical Background), there have been periodic reviews of our knowledge in the subject area. Cott 1940 was mainly concerned with animal coloration. Subsequent reviews, such as Edmunds 1974 and Ruxton, et al. 2004, have focused on types of mimicry associated with defense from predators. -

In view of the importance of sampling these areas, the present study conducted the first butterfly inventory of a coastal area in the state of Paraná. Samples were taken in the Floresta Estadual do Palmito, from February 2014 through January 2015, using insect nets and traps for fruit-feeding butterfly species. A total of 200 species were recorded, in the families Hesperiidae (77), Nymphalidae (73), Riodinidae (20), Lycaenidae (19), Pieridae (7) and Papilionidae (4). Particularly notable records included the rare and vulnerable Pseudotinea hemis (Schaus, 1927), representing the lowest elevation record for this species, and Temenis huebneri korallion Fruhstorfer, 1912, a new record for Paraná. These results reinforce the need to direct sampling efforts to poorly inventoried areas, to increase knowledge of the distribution and occurrence patterns of butterflies in Brazil. Key words: Atlantic Forest, Biodiversity, conservation, inventory, species richness. INTRODUCTION the importance of inventories to knowledge of the fauna and its conservation, the present study inventoried the species of Faunal inventories are important for providing knowledge butterflies of the Floresta Estadual do Palmito. -

Polymorphism Under Apostatic
Heredity (1984), 53(3), 677—686 1984. The Genetical Society of Great Britain POLYMORPHISMUNDER APOSTATIC AND APOSEMATIC SELECTION VINTON THOMPSON Department of Biology, Roosevelt University, 430 South Michigan Avenue, Chicago, Illinois 60805 USA Received31 .i.84 SUMMARY Selection for warning colouration in well-defended species should lead to a single colour form in each local population, but some species are locally polymor- phic for aposematic colour forms. Single-locus two-allele models of frequency- dependent selection indicate that combined apostatic and aposematic selection may maintain stable polymorphism for one, two or three aposematic forms, provided that at least one form is subject to net apostatic selection. Frequency- independent selective differences between colour forms broaden the possibilities for aposematic polymorphism but lead to monomorphism if too large. Concurrent apostatic and aposematic selection may explain polymorphism for warning colouration in a number of jumping or moderately unpalatable insects. 1. INTRODUCTION Polymorphism for warning colouration poses a paradox for evolutionists because, as Fisher (1958) seems to have been the first to note, selection for warning colouration (aposematic selection) should lead to monomorphism. Under aposematic selection predators tend to avoid previously encountered phenotypes of undesirable prey, so that the fitness of each phenotype increases as it becomes more common. Given the presence of two forms, each will suffer at the hands of predators conditioned to avoid the other and one will eventually prevail because as soon as it gets the upper hand numerically it will drive the other to extinction. Nonetheless, many species are polymorphic for colour forms that appear to be aposematic. The ladybird beetles (Coccinellidae) furnish a number of particularly striking examples (Hodek, 1973; and see illustration in Ayala, 1978).
