Cascading Chromosomal Speciation in Lizards: A Second Look

Sites, Jack W Jr; Thompson, Pamela; Porter, Calvin A (University of Hawaii Press, 1988)

The extent of Robertsonian chromosomal variation in the iguanid lizard Sceloporus grammicus of Mexico is exceptional among lower vertebrates, and this case has been the basis for the cascading chromosomal speciation ...
Constitutive Heterochromatin Differentiation and Evolutionary Divergence of Karyotype in Oriental Anopheles (Cellia)

Baimai, Visut (University of Hawaii Press, 1988)

Analysis of the mitotic karyotype of two clusters of closely related species of oriental Anopheles, the A . balabacensis and A. maculatus complexes, has revealed interspecific differences in the amount and distribution ...
Contrasting Patterns of Differentiation Inferred from Traditional Genetic Markers in the Process of Speciation

Sene, Fabio Melo; Pereira, Maria Augusta Querubim Rodrigues; Vilela, Carlos Ribeiro (University of Hawaii Press, 1988)

Populations of Drosophila serido from various geographic origins were characterized using four markers: morphology of male genitals, inversions in polytene chromosomes, morphology and heterochromatin of metaphase chromosomes, ...
Evolutionary Relationships of the Hawaiian and North American Telmatogeton (Insecta; Diptera: Chironomidae)

Newman, Lester J (University of Hawaii Press, 1988)

Species of Telmatogeton and the closely related genus Paraclunio generally live on the rocky shores of the intertidal zone. Species of Telmatogeton have evolved from the marine environment into torrential freshwater streams ...
Identification of Mullerian Chromosomal Elements in Hawaiian Drosophila by in situ DNA Hybridization

Jeffery, Duane E; Farmer, James L; Pliley, Michael (University of Hawaii Press, 1988)

We have hybridized Drosophila melanogaster DNA sequences to polytene chromosomes of D. silvestris. The results support Muller's hypothesis that the chromosomal elements have been largely conserved in the evolution of ...

Mating Asymmetries and Phylogeny in the Drosophila melanogaster Species Complex

Robertson, Hugh M (University of Hawaii Press, 1988)

The propensities for interspecific courtship and mating among the four species of the Drosophila melanogaster species complex were studied to examine Kaneshiro's hypothesis relating asymmetrical interspecific mating ...
On Defining Species in Terms of Sterility: Problems and Alternatives

Paterson, Hugh (University of Hawaii Press, 1988)

Despite its historic role as a criterion of species status, intersterility sensu lato is not an acceptable characteristic for delineating the genetic species or field of gene recombination. This conclusion is not new ...
The Role of Heterochromatin in Karyotype Variation Among Hawaiian Picture-Winged Drosophila

Clayton, Frances E (University of Hawaii Press, 1988)

A comparison is made of the amount and distribution of heterochromatin in the mitotic chromosomes of species of the Hawaiian picture-winged Drosophila, and metaphase configurations among these species are compared with ...
Sex Determiners and Speciation in the Genus Chironomus

Martin, Jon; Lee, BTO (University of Hawaii Press, 1988)

In a group of closely related Australian Chironomus species, the position of the sex-determining region is variable, not only in different species (or forms) but , in at least one case, also within the same form. This ...
Speciation in the Neotropics and the Founder Principle

do Val, Francisca C (University of Hawaii Press, 1988)

The association of bottleneck effects and speciation patterns observed in South American flies Drosophila paulistorum, lizards Anolis chrysolepis and Mabuya arajara, and frogs in the genus Cycloramphus is briefly ...
