PALYNOLOGY AND PHYLOGENY OF THE ARACEAE

GRAYUM, MICHAEL HOWARD 01 January 1984 (has links)
An extensive survey of external pollen morphology in the monocot family Araceae was undertaken, using both light and scanning electron microscopy. Pollen of approximately 380 species was examined, representing 103 of the 111 currently recognized genera. The data collected were analyzed to determine polarities for the character-states of each major pollen character. The most primitive pollen in Araceae is regarded as monosulcate, boat-shaped, heteropolar, bilaterally symmetrical and small to medium-sized. It is shed in monads, has foveolate to reticulate exine sculpturing and is probably tectate-columellate. The evolution of pollen exine type in Araceae may be explained in part by pollinator type. The two most advanced exine types--psilate and spinose--are very closely associated with pollination by beetles and flies, respectively. Two embryological aspects of araceous pollen were investigated: nuclear number and starch content. Binucleate, starchless pollen clearly represents the primitive condition in Araceae. The presence of starch in aroid pollen is primarily related to pollen size--i.e., larger grains are much more likely to store starch. The phylogenetic relationships of pertinent infrafamilial aroid taxa were analyzed using pollen and all other available characters, resulting in an informal cladogram and a preliminary new classification for the family. Major deviations of this system from the standard classification of Engler include: the referral of Acorus to its own monotypic family, and of Gymnostachys to its own subfamily; the merger of the subfamilies Pothoideae and Monsteroideae; the dissolution of Calloideae; the radical emendation of the subfamily Lasioideae; the enlargement of the subfamily Philodendroideae to include several tribes from the Lasioideae and Aroideae; a drastic internal rearrangement of the Colocasioideae; the reduction in size of the Aroideae, plus the insertion of Pistia in this subfamily and the consequent abandonment of the subfamily Pistioideae. The relationship of the Araceae to other families was briefly considered. The Araceae are in general considered more closely related to the Alismatiflorae than to the Areciflorae, Typhales or Piperales. The Lemnaceae are not closely related to Pistia, and their relationship to the Araceae in general needs to be reassessed.

Establishing fundamental theories for internet atlas realisation with application in the Brazilian primary education system.

da Silva Ramos, Cristhiane, cristhiane.ramos@rmit.edu.au January 2006 (has links)
This thesis addresses a research programme that aimed to provide an open standard methodology for publishing Brazilian local primary school atlases on the World Wide Web. It also aims to contribute to the use of computer laboratories provided to Brazilian primary schools by the Brazilian government. Using a local school atlas as the source of information, a Web-based prototype of the School Atlas of Rio Claro (SP) was developed in SVG (Scalable Vector Graphics). SVG is a vector-based standard for publishing interactive graphics on the Web validated by the Web Consortium. This prototype was tested with a group of Brazilian primary school teachers. The test was conducted with fourteen teachers, all of them were familiar with the paper version of the School Atlas. During weekly meetings, the participants took notes to discuss and reflect about the practices held in school with local maps. The main test carried out with teachers was to prepare a paper activity based on the atlas content. The idea behind this activity was to foster teachers to leave a passive role as mere users and interact with the product in a more active fashion. In order to enable them to take full advantage of simple digital tools they were briefly trained to capture screen, use image editing software (they were instructed on the use of Paint, an image editing application available in Windows), and to copy text from the atlas. The results demonstrated that the teachers were keen to interact with the product and, although reproducing some common practices of paper atlas use, they revealed a deep interest on the use of the Internet as a medium for education and the prototype itself. A second test was carried out with a group of atlas developers. They were given a time frame of two weeks to develop an SVG-based atlas using the methodology proposed in this research. They completed the task within the time frame proposed however they indicated that more specific training should be desirable; this finding indicates the need to introduce digital map publishing as a subject to be taught in geosciences undergraduate courses in Brazil. It is believed that open standard methodology proposed here can be applied to other cities also developing local atlases for early geographical education.

A computational approach to the cartographic dot distribution problem

Hickey, Mutahar January 1993 (has links)
In the field of cartography, there is occasionally a need to create a distribution of dots on a map. These dots should give an impression of the density of some countable object set. This type of map is called a "Dot Distribution Map".Up to the current time, if the dots are to represent reality at all, they have to be placed by hand by a cartographer using a digitizing tablet or other input device. This is due to the fact that a census of a region gives only a total, yet it is known that the densities vary within that region. A cartographer can look at all the data available about a region and then can make judgements about how the densities will change within the region. He then can place dots which represent his interpretation of reality.This thesis states that there exists an algorithm which would assign dots to a map based upon the common belief that the density will gradate smoothly from one region with one census value to another region with a different census value.The approach taken was to relate the Map regions to polygons and to then subdivide the polygons into triangles. These triangles would then be subdivided into six children recursively and the data stored in a hex-tree. This is the current level of development. the next steps will be:Generate a surface above the 2-D map based upon the known input data of counts for the various regions.From the centroid for each existing leaf on the Hex-Tree, find the corresponding Zi value from the surface information. From each of these leaves, recursively subdivide the triangle further until the number of dots indicated by the Zt. value can be placed on the map. / Department of Computer Science
