Bibliography: leaves 107-117. This thesis examines the rationale for managing biological diversity on a regional basis and develops recommendations for the use of two computational methods in biodiversity management planning by conducting a case study in the Flinders Ranges, centred on the Yellow-footed Rock Wallaby (abstract)

This parental care deficits is crucial to offspring s emancipation that involve abilities development to they survive independently. In this work we observe 16 Red-footed boobies chick (Sula sula) on different stages of development, at area of Parque Nacional Marinho of Fernando de Noronha s archipelago, from August to October of 2005. Our data show the parents presence decrease during chick development and an activity frequency modification, in move and fly, which suggest the emancipation s chick development. We observe also the action of Kleptoparasits and the influence with offspring parental care. Our data show consistency with the literature. However, we consider that studies carried through during the peak of the reproductive station can support the hypothesis of that the conflicts, together with the initial period of development of the flight, can be representative in terms of mortality of chicks for the studied species / Os custos do cuidado parental tendem a aumentar com o decorrer do tempo, principalmente devido ? incapacidade dos pais atenderem ?s crescentes necessidades alimentares da prole. Esse d?ficit no cuidado parental ? crucial para a emancipa??o da prole no que se refere ao desenvolvimento de suas habilidades para sobreviver independentemente. Neste trabalho observamos 16 filhotes de Atobas-de-p?s-vermelhos (Sula sula) em diferentes est?gios de desenvolvimento durante o per?odo de agosto at? outubro de 2005, na ?rea do Parque Nacional Marinho do Arquip?lago de Fernando de Noronha / PE. Os dados apontaram a diminui??o da presen?a dos pais ao longo dos est?gios de desenvolvimento do filhote, juntamente com altera??es nas freq??ncias de atividades como deslocamento e v?o, que sugerem o desenvolvimento da emancipa??o do filhote. Ainda observamos a a??o de cleptoparasitas e sua influ?ncia no cuidado com a prole. Os dados mostraram-se consistentes com a literatura. Contudo, propomos que estudos realizados durante o pico da esta??o reprodutiva podem sustentar a hip?tese de que os conflitos, juntamente com o per?odo inicial de desenvolvimento do v?o, podem ser representantes em termos de mortalidade de filhotes para a esp?cie estudada

5 ABSTRACT This doctoral thesis is focused on flat-footed fly families Opetiidae, Platypezidae and genus Microsania (Insecta: Diptera). The thesis consists of general introduction to the systematics, taxonomy, diversity, zoogeography, phylogeny, and biology of the flat-footed flies. Systematics and taxonomy are summarized based on historical as well as recent literature. Each important taxon is shortly introduced and information about its taxonomy, morphology, diversity, distribution, and biology is provided. The next two chapters deal with fossil species and research on species diversity. The following part is a summary and plan for future research. Final chapter consists of 9 published peer-reviewed articles (5 in impacted international journals and 4 in journals without impact factor). The first article is a molecular phylogeny study of relationships between genera of flat- footed flies. The results show Platypezidae consisting of two well-supported clades, the first with the subfamilies Melanderomyiinae + Callomyiinae and the second formed by subfamily Platypezinae. Genus Microsania was resolved as a separate lineage distant from Platypezidae which clustered with Opetiidae as its sister group, both together forming a sister group to Platypezidae. The genus Agathomyia proved to be paraphyletic....
