This book was released on 2009-08 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: The modified mouthparts group is perhaps the largest of the four major Hawaiian Drosophila clades, yet has received relatively little taxonomic attention during the past 40 years. This study reviews unplaced species and the ceratostoma, freycinetiae, semifuscata, and setiger subgroups, with descriptions of 22 new species. We hope this work encourages greater study of the biology of this important group.

Available in PDF, EPUB and Kindle. Book excerpt: The Hawaiian Islands have been recognized as an ideal place to study evolutionary processes due to their remote location, multitude of ecological niches and diverse biota. As the oldest and largest radiation in the Hawaiian Islands the Hawaiian Drosophilidae have been the focus of decades of evolutionary research and subsequently the basis for understanding how much of the diversity within these islands and other island systems have been generated. This dissertation revolves around the diversification of a large clade of Hawaiian Drosophila, and examines the molecular evolution of this group at several different temporal scales. The antopocerus, modified tarsus, ciliated tarsus (AMC) clade is a group of 90 described Drosophila species that utilize decaying leafs as a host substrate and are characterized by a set of diagnostic secondary sexual characters: modifications in either antennal or tarsal morphologies. This research uses both phylogenetic and population genetic methods to study how this clade has evolved at increasingly finer evolutionary scales, from lineage to population level. The first chapter resolves the relationships within the AMC lineage, delimiting species group and subgroup relationships for the first time. This work complements recent phylogenetic studies focused on other lineages of Hawaiian Drosophila, most notably of the picture wing clade. This dissertation presents the most comprehensively sampled data set for the AMC in terms of both species and phylogenetic characters. The AMC clade is strongly supported as monophyletic and relationships among of the five major lineages in this radiation are proposed. Molecular dating analyses indicate a rapid radiation occurred about four million years ago, giving rise to all the extent lineages of AMC species. Interestingly, the AMC does not strictly follow the progression rule common to many other Hawaiian taxa. By comparing this lineage to other Hawaiian Drosophila lineages it is hypothesized that an initial burst of speciation occurred following colonization of the main Hawaiian Islands ands its magnitude was correlated with sexual selection within each group. Focusing more specifically on the spoon tarsus subgroup within the AMC, I redescribe this subgroup in chapter two. The species boundaries in this group are discussed in light of diagnostic secondary sexual characters of males. Drosophila septuosa Hardy is regarded as a junior synonym of Drosophila percnosoma Hardy. A new species, Drosophila kikalaeleele, is described. Drosophila fastigata Hardy, a species endemic to O`ahu, is added to the species subgroup, bringing the total number of known species to 12. An updated key to species is provided to the spoon tarsus subgroup. I employ several methods to delimit relationships at the species/population interface to get a more refined view of the evolution of this subgroup in chapter three. Eight of the twelve species in this subgroup are found only on the Island of Hawaii, suggesting that they have diverged within the past 500,000 years. This rapid diversification has made determining the relationships within this group difficult. We find widespread agreement between phylogenetic estimates derived from different methods. Notably, our analyses suggest that the spoon tarsus subgroup, as currently defined, is not monophyletic. The last chapter in this dissertation explores how biogeography influences microevolution within the spoon tarsus species, Drosophila waddingtoni, to understand the forces that drive macroevolution within the AMC clade. Previous chapters show that D. waddingtoni originated on the youngest island, Hawaii, and subsequently colonized the older islands of the Maui Nui complex, the opposite direction predicted by the progression rule. The recent origin of Hawaii suggests that this species will provide unique insight into the dynamics of recent island colonization events. Three nuclear and three mitochondrial genes are used to study gene flow and divergence following founder events. Biogeographic patterns, coupled with divergence time estimates suggest that the back colonization to Maui Nui occurred within the past 250,000 years and has since not led to significant population differentiation. These data also demonstrate that while migration between islands is possible and present in this species, it is not frequent enough to homogenize populations. Biogeography is identified as being a major driver in the diversification of this species. The AMC clade is a useful tool in understanding diversification in the Hawaiian Islands and rapid radiations in general. By examining this lineage from several different evolutionary timescales this dissertation research elucidates the processes involved in generating and maintaining diversity at all taxonomic levels. This research is also useful in extrapolating how evolution drives diversity in other Hawaiian Drosophilidae clades and other native Hawaiian lineages as well.

Book excerpt: Concerns about global biodiversity are rising dramatically, yet we are lagging behind in the most basic prerequisite for its understanding and conservation: the inventory. Insect species may make up five or ten times the number of all other plant and animal species combined, and as such they represent one of the major challenges in biosystematic science. World Catalogue of Insects is an initiative aiming at compiling worldscale, authoritative catalogues of monophyletic insect taxa. Volumes in this series contain standard nomenclatoral information on all names pertaining to the taxon treated, including type locality and distribution to the extent this is relevant. Additional information is optional, e.g., location, status and condition of types; biology; bibliographical information; pest status; vector status; etc. This volume nine focuses on Drosophilidae (Diptera).

This book was released on 2013-08-09 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 101 Mecyclothorax carabid beetle species of Tahiti, French Polynesia comprise a very diverse adaptive radiation. Given Tahiti?s surface area of only 1,045 km2, the island?s Mecyclothorax fauna represents the densest, most diverse radiation of species on Earth. Speciation of Tahitian Mecyclothorax has also occurred very rapidly, with closely-related species allopatrically distributed across geographic ranges defined by Tahiti?s incredibly complex geological topography. Such high levels of endemism are useful for conservation management, as continuing presence of these beetles in small areas of Tahitian forest can signify good health of the native biota in those areas. This taxonomic revision includes dichotomous keys and diagnostic photographs supporting identification of all 101 species, over one-quarter newly described in this publication. Each species treatment includes ecological and geographical information. This monograph illuminates an important component of Tahitian biodiversity in support of ongoing efforts to conserve Tahiti?s biological resources.

Book excerpt: Anyone wishing to tap the research potential of the hundreds of Drosophila species in addition to D.melanogaster will finally have a single comprehensive resource for identifying, rearing and using this diverse group of insects. This is the only group of higher eukaryotes for which the genomes of 12 species have been sequenced.The fruitfly Drosophila melanogaster continues to be one of the greatest sources of information regarding the principles of heredity that apply to all animals, including humans. In reality, however, over a thousand different species of Drosophila exist, each with the potential to make their own unique contributions to the rapidly changing fields of genetics and evolution. This book, by providing basic information on how to identify and breed these other fruitflies, will allow investigators to take advantage, on a large scale, of the valuable qualities of these other Drosophila species and their newly developed genomic resources to address critical scientific questions. * Provides easy to use keys and illustrations to identify different Drosophila species* A guide to the life history differences of hundreds of species* Worldwide distribution maps of hundreds of species* Complete recipes for different Drosophila diets* Offers an analysis on how to account for species differences in designing and conducting experiments* Presents useful ideas of how to collect the many different Drosophila species in the wild
