A morphological (non-molecular) cladistic analysis of the Velloziaceae is presented. The terminal taxa are 47 species of Velloziaceae plus four taxa as outgroups: Acanthochlamys bracteata (Acanthochlamydaceae), Encholirium scrutor (Bromeliaceae), Thoracocarpus bissectus (Cyclanthaceae) and Pandanus racemosus (Pandanaceae). The species of Velloziaceae sampled represent a significant proportion of the morphological diversity of the family, including all recognized genera and sections. The analysis revealed two major groups within Velloziaceae, supported mainly by stomata, vascular bundles in the pedicel, aquiferous tissues, filaments, anthers, pollen, stigma, seeds, ploidy and chemical characters. Comparison between this and the previous phylogenetic hypotheses for Velloziaceae, together with the two conflicting current classifications, suggests that there is incompatibility concerning the support of current genera and sections. The only three groups supported in all phylogenies are Barbacenioideae sensu Menezes (= Barbacenia sensu Smith & Ayensu), Xerophyta sect. Barbacenioides and Xerophyta sect. Xerophyta sensu Smith & Ayensu. © 2005 The Linnean Society of London, Botanical Journal of the Linnean Society , 2005, 148 , 157–173. 相似文献

Conventional actions denoting differences in rank are considered a central part of a Mayan ritual honoring a local saint and provide the basis for the formal analysis presented here. The ritual elements—acts drawn from daily etiquette and other ritual contexts—are combined in a way consistent with classic theories of ritual. While providing the basis for a formal argument, ways of designating rank order are not treated as "empty ritual": they pose a moral problem for the participants that contributes to the meaning of the ritual itself. 相似文献

Lessons learned in developing community mental health care
in Latin American and Caribbean countries
DENISE RAZZOUK GUILHERME GREG��RIO RENATO ANTUNES JAIR DE JESUS MARI 《World psychiatry》2012,11(3):191-195
This paper summarizes the findings for the Latin American and Caribbean
countries of the WPA Task Force on Steps, Obstacles and Mistakes to Avoid
in the Implementation of Community Mental Health Care. It presents an overview
of the provision of mental health services in the region; describes key experiences
in Argentina, Belize, Brazil, Chile, Cuba, Jamaica and Mexico; and discusses
the lessons learned in developing community mental health care. 相似文献

Abstract: Fossil testate amoebae and their non‐marine finds are rare so their ecological importance through Earth history is poorly understood. The Lower Jurassic shallow water black‐shales of Trento Platform (north‐east Italy) are rich in micro‐organisms and contain a thecamoebian and ostracod assemblage representing the first known record of Early Jurassic oligohaline forms from the European mainland. The thecamoebians are represented by the genera Difflugia, Pontigulasia and Centropyxis. The present discovery of Lower Jurassic thecamoebians in fine carbonate organic‐rich deposits indicates, for the first time, that these sediments can preserve testate amoebae very well. The occurrence of difflugid testate amoebians confirm a transitional marine‐terrestrial habitat, outside large bodies of water, and suggests occasional eutrophication in ephemeral restricted aquatic environment in the Sinemurian–Pliensbachian Trento Platform. 相似文献
