This study aimed to identify potential factors responsible for geographically structured morphological variation within the widespread Australian frogs Limnodynastes tasmaniensis Gunther and L. peronii Dumeril & Bibron. There was support for James's rule, and both latitude and present climate explained large amounts of the variation in body size and shape (particularly in L. peronii). There was also some support for the influence of several biogeographical barriers. Finally, both species were sexually dimorphic for body size and the degree of sexual size dimorphism (SSD) varied geographically. Climate was an important explanation for SSD variation in L. peronii, while latitude was most important for L. tasmaniensis. Geographical variations in sexual selection via male-male physical competition and climate-related resources are suggested as potential explanations for SSD variation in L. peronii.

Este estudo surgiu da inquietação da autora sobre a eficiência da comunicação no ensino e orientação sexual nas comunidades religiosas. E como se dá tal ensino nas Organizações Ecumênicas. Para tanto, foram escolhidas organizações ecumênicas que tem como um de seus objetivos a educação à população e desenvolvem efetivo trabalho na área de educação e orientação sexual. As organizações ecumênicas, objeto deste estudo são: Conselho Latino Americano de Igrejas-CLAI, KOINONIA -Presença Ecumênica e Serviço, Coordenadoria Ecumênica de Serviço-CESE e Diaconia. Tal escolha não foi ao acaso, mas pelo fato das referidas organizações comporem a RES-Rede Evangélica de Solidariedade. Ao longo do estudo dos folhetos e livretos disponibilizados às Igrejas membros foi possível perceber a dificuldade de diálogo entre ciência e bíblia quando o assunto é sexualidade. Levantou-se a necessidade de novas teorias que dê conta de explicações coerentes sobre o que é sexualidade e como transmiti-la à comunidade religiosa, tornando, esse ensino, enriquecedor, verdadeiro e livre de preconceitos e discriminações. Verificou-se que a comunidade religiosa tem em sua forma de pensar alguns preceitos doutrinários, porém a aplicação de tais preceitos nem sempre é possível por viverem em uma sociedade que oferece possibilidades de práticas sexuais livres, mesmo sendo essas reprovadas pelo estilo de vida escolhido pelos cristãos. Eles, os cristãos, não estão imunes de tais práticas. Necessitando assim orientações esclarecedoras de seus lderes sobre o assunto, uma vez que esses são vistos como os que têm legitimidade para tratar qualquer assunto na comunidade.(AU)

This thesis provides the first detailed study of maximal oxygen consumption of turbot on a fish farm over a range of fish sizes and temperatures. Also provided is a study of the diets used in turbot farming and the development of a diet that contains no fresh fish. A detailed study of previous research on flatfish nutrition, identified fresh fish, sprat in particular, as the optimum diet for turbot farming. A series of experiments was undertaken that confirmed this and also identified one possible explanation for the optimum performance of sprat, as a function of high non-protein energy ratios in sprat. This factor was exploited in the production of a diet containing no fresh fish and which produced superior results to diets containing fresh fish; the optimum level of lipid in the diet was determined as 18%. The study of oxygen consumption was on fully-fed fish so that maximum demand could be quantified. Continuous monitoring of tank water oxygen levels enabled the calculation of the Specific Dynamic Action (SDA) effect in turbot and the relation of it to dietary energy. Variation of SDA with the dietary energy profile was identified as a contributing factor to differential fish growth on various diets. Finally, the implications of this work to fish farming were considered. Economic appraisal and comparison of the diets routinely used in turbot farming identified that the diet developed as a result of this work, ie the diet containing no fresh fish protein, was more cost effective on the basis of the production of one tonne of turbot. The study of oxygen consumption enables water supply to be calculated for any fish size between 1g and 1000g between the temperatures of 7® C and 16® C. The quantification of SDA enables correct adjustment of oxygen flows according to the feeding status of the fish.

Brazilian pepper (Schinus terebinthifolius) is an exotic shrub or small tree that has become well established as an invasive and highly competitive species through much of southern Florida. Love vine (Cassytha filiformis), a native parasitic plant, was noted parasitizing Brazilian pepper, apparently affecting its health. The objective of this study was to investigate the nature of this parasitic interaction in southern Florida. Brazilian pepper populations were studied to determine whether parasitism by love vine may affect growth and reproduction. Anatomical studies of love vine parasitizing Brazilian pepper determined physical aspects of the parasitic interaction at the cell and tissue level. Physiological aspects of this interaction were investigated to help describe love vine resource acquisition as a parasite on host Brazilian pepper plants, and as an autotrophic plant. An investigation of ecological aspects of this parasitic interaction was done to determine whether physical or biological aspects of habitats may contribute to love vine parasitism on Brazilian pepper. These studies indicated that: (1) parasitism by love vine significantly decreased growth and reproduction of Brazilian pepper plants; (2) anatomical and physiological investigations indicated that love vine was primarily a xylem parasite on Brazilian pepper, but that some assimilated carbon nutrients may also be acquired from the host; (3) love vine is autotrophic (i.e., hemiparasitic), but is totally dependent on its host for necessary resources; (4) the occurrence of love vine parasitism on Brazilian pepper is mediated by physical characters of the biological community. ^
