Chromosomal evolution in the South American Riodinidae (Lepidoptera: Papilionoidea).
We give the haploid chromosome numbers of 173 species or subspecies of Riodinidae as well as of 17 species or subspecies of neotropical Lycaenidae for comparison. The chromosome numbers of riodinids have thus far been very poorly known. We find that their range of variation extends from n = 9 to n = 110 but numbers above n = 31 are rare. While lepidopterans in general have stable chromosome num...
متن کاملChromosomal Diversity and Karyotype Evolution in South American Macaws (Psittaciformes, Psittacidae)
Most species of macaws, which represent the largest species of Neotropical Psittacidae, characterized by their long tails and exuberant colours, are endangered, mainly because of hunting, illegal trade and habitat destruction. Long tailed species seem to represent a monophyletic group within Psittacidae, supported by cytogenetic data. Hence, these species show karyotypes with predominance of bi...
متن کاملRecurrent Evolution of Melanism in South American Felids
Morphological variation in natural populations is a genomic test bed for studying the interface between molecular evolution and population genetics, but some of the most interesting questions involve non-model organisms that lack well annotated reference genomes. Many felid species exhibit polymorphism for melanism but the relative roles played by genetic drift, natural selection, and interspec...
متن کاملChromosomal Evolution in Chiroptera
Chiroptera is the second largest order among mammals, with over 1300 species in 21 extant families. The group is extremely diverse in several aspects of its natural history, including dietary strategies, ecology, behavior and morphology. Bat genomes show ample chromosome diversity (from 2n = 14 to 62). As with other mammalian orders, Chiroptera is characterized by clades with low, moderate and ...
متن کاملChromosomal Evolution
The possibility that the Peromyscus maniculatus complex of deer mice arose via the process described as "centrifugal speciation" (Brown, 1957) has been discussed by Bowers et a l . , 1973, Lawlor, 1974, Baker et al., 1975, and Greenbaum et a l . , 1978. This study was designed to yield additional da ta on the cytogenetics of three species of this complex in order to evaluate the "centrifugal sp...
