The freshwater fish fauna of southern Australia is characterised by low species richness and high endemism in groups displaying southern temperate, temperate-subtropical or temperate-tropical distributions. Comparatively few studies in Australia have incorporated modern molecular techniques to delineate species boundaries and define within-species conservation units. This is problematic because freshwater fishes are likely to show high levels of cryptic speciation and marked spatial sub-structure, and is information which is needed to conserve biological diversity and maintain the integrity of ecological communities and processes. The current study uses a ‘combined evidence’ approach, led principally by a set of nuclear genetic markers (allozymes), to assess species boundaries, spatial sub-structure and conservation units in obligate freshwater fishes from southern Australia. A literature review (Chapter 2) concerns the nature and effects of fragmentation in freshwater environments. It considers the implications for freshwater fishes and the types of extrinsic and intrinsic characteristics, both natural and human accelerated, that might drive population fragmentation and divergence. This theoretical framework is then applied to a suite of six largely co-occurring species groups with contrasting biological characteristics, and derive hypotheses about expected levels of genetic divergence across and within different drainages. Major findings Species of Retropinna (Chapter 3) are widespread and generally regarded as ‘common’ and mobile. Allozyme analyses revealed species-level and population-level sub-divisions, including five distinct species with contiguous ranges and no evidence of genetic exchange. Three occur along the eastern seaboard (including three instances of sympatry), another in coastal and inland southeastern Australia and Tasmania, and a fifth in the Lake Eyre Basin. There is no indication of a simple ‘tasmanica’ versus ‘semoni’ dichotomy, but instead a complex pattern involving discrete clusters for the Upper Murray plus Darling rivers, Lower Murray, Glenelg River and Tasmanian regions. These findings have implications for biodiversity, conservation and ecology. This chapter has been published in modified form (Marine and Freshwater Research 58, 327- 341). Nannoperca obscura (Chapter 4) is a small demersal fish with specialised habitat requirements. It is under threat of extinction, particularly in the western section of its range. Combined nuclear and matrilineal genetic data identified congruent within-species sub-structure, divided by patternsof distribution and biogeography. Four monophyletic mtDNA lineages, each distinct at multiple nuclear loci, indicate four Evolutionarily Significant Units (ESUs), namely (1) Lake Alexandrina in the Murray-Darling Basin (MDB), (2) Glenelg River, Millicent Coast River Basin and the outlying Mt Emu Creek, (3) Merri River and associated coastal streams, and (4) the eastern range section. Additional genetic and ecological data support multiple Management Units (MUs) within ESUs for individual or groups of river basins separated by marine barriers. Nannoperca australis (Chapter 5) has a similar character to its aforementioned congener, except that it occurs across a much wider area. Although generally common, particular populations are threatened, especially in the MDB. Allozyme analyses of 57 populations confirm the presence of two divergent species, with an eastern species containing two ESUs: (1) Gippsland and Flinders Island, and (2) Ansons River in northeastern Tasmania. The western species shows sub-structure across its range, including a separation of MDB and coastal populations as two heterogenous ESUs. The Lower Murray region (Mount Lofty Range streams and the Lower Lakes) harbours a remarkable level of between- and within-population diversity, underscoring its importance for conserving evolutionary potential. Mogurnda adspersa (Chapter 6) has been presumed extinct in South Australia since the early 1970s and has also been assumed lost from the southern MDB. This chapter reports on the rediscovery of M. adspersa from a wetland near the terminus of the Lower Murray, some 2500 river kilometres from the nearest known population. The nature and basic ecology of this population is documented, but the combined effects of drought and water abstraction recently have led to the probable extirpation of the wild population. A combined allozyme and mtDNA dataset confirmed the ‘nativeness’ of the population as a distinct sub-population (and MU), with a moderate level of allele heterogeneity. This information provides a platform for captive breeding as a conservation measure. The endemic genus Philypnodon (Chapter 7) contains two nominal species: P. grandiceps and the long recognised but only recently described P. macrostomus. The former is considered widespread and common (near ubiquitous), whereas the latter is more patchily distributed. Some tolerance to marine conditions is indicated, suggesting that there may be less sub-structure, but allozyme analyses of 269 individuals indicate the presence of multiple, species-level taxa within both described species. This obscures interpretations of existing ecological data. Although the presence of genetically-similar populations within and across some drainage divides indicates higher levels of gene flow, the pattern is complex and suggests historic genetic exchange between some but not other geographically-adjacent taxa. The freshwater blackfish genus Gadopsis (Chapter 8) has been a problem group for taxonomists, and it is unclear where the group is placed phylogenetically and how many species occur. Northern and southern forms on respective sides of the Great Dividing Range have been proposed, but with limited supporting evidence. Its dispersal ability (hence predicted genetic structure) is obscured by opposing life-history traits, including large body size (i.e. good swimming ability) versus habitat specialisation, demersal larvae and restricted home ranges. This chapter provides a genetic overview incorporating 61 locations across the range, and demonstrates unequivocally the presence of distinct northern and southern species of G. ‘marmoratus’. Moreover, distinct genetic discontinuities involving geographically abutting lineages indicate the likely presence of multiple ESUs within each species. A comparison of the allozyme data with previous mtDNA studies also identified two ESUs within G. bispinosus. Overall, considerable complexity is demonstrated signalling the need for a review of how the southern Australian fish fauna should be viewed, studied and protected. The genetic data also provide insight into the interplay of intrinsic biological characters (e.g. dispersal ability, population ecology) with historic and contemporary extrinsic environmental factors (e.g. fragmentation, biogeographic processes). Comparisons between and within traditionally-defined species are problematic, however, owing to multiple species-level splits and other genetic divisions that may have matching biological counterparts. Together with other reports in the literature, the findings presented herein have significant conservation implications, particularly given the rapid pace of human-mediated change in some regions that house high species and genetic diversity and unique evolutionary components, notably southeastern Queensland (especially the Mary River) and the lower River Murray in South Australia. Other regions displaying high genetic substructure or divergent populations include the Clarence River and Lachlan River in New South Wales; Gippsland, Goulburn River, Glenelg River and Mt Emu Creek in Victoria, and the Macquarie River and Ansons River in Tasmania. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1339749 / Thesis (Ph.D.) - University of Adelaide, School of Earth and Environmental Sciences, 2008

The objective of this thesis is to develop an ecological economic framework for the assessment and establishment of protected areas (PAs) that are aimed at conserving forests and biodiversity. The framework is intended to be both rigorous and relevant to the decision-making process. Constructivism is adopted as the paradigm guiding the research process of the thesis, after firstly examining also positivist philosophy and ???post-normal??? scientific methodology. The tenets of both ecological and environmental economics are then discussed. An expanded model of human behaviour, which includes facets derived from institutional economics and socioeconomics as well as aspects of neoclassical economics, is outlined. The framework is further developed by considering, from a contractarian view point, the implications of intergenerational equity for biodiversity conservation policies. The issues of intragenerational distribution and allocation are then considered. In this regard, cost-benefit analysis (CBA), as applied to the valuation of forests, PAs, and biodiversity, is critically reviewed. A participatory approach to decision-making, which may also include CBA, is then proposed. The resulting ecological economic framework may be thus summarised: (a) ecosystem use patterns should be chosen on the basis of their sustainability, distributional, and efficiency aspects; (b) systems of PAs should be established in order to achieve minimal intergenerational equity; (c) intragenerational equity requires the correction of the asymmetrical distribution of the costs and benefits arising from the establishment of PAs; (d) the institutional features relevant to the environmental-economic issues being analysed should be considered; and (e) the decision-making process should be participatory and action oriented. The framework is applied to two case studies in Vanuatu. These applications detail (a) stakeholders??? views and trade-offs faced in relation to forest management (b) modes of participatory research and decision-making, (c) forms of compensation that may be adopted in correcting asymmetrical distributions of the costs and benefits of PAs, and (d) institutional influences on ecosystems use and implications for conservation projects. The institutional arrangements developed for the establishment of the PAs are presented. The application of this ecological economic framework has resulted in the formal establishment of one PA and the identification and assessment of five other PAs.

Orientador: Valdemir Antonio Rodrigues / Banca: Antônio de Pádua Sousa / Banca: Luiza Helena Duenhas / Abstract: The preservation of the biodiversity of the vegetation in the micro watershed is of basic importance for the maintenance of the animal and vegetal wild life, ambient services and protection of the biosfera. The morphometry is a tool of great importance as diagnostic of susceptibility to the ambient degradation or conservation and guides the planning and handling of the micro watershed. The present study had as objective the morphometric characterization and analysis of biodiversity in the micro watershed of the Edgárdia Farm, Botucatu - SP. The micro watershed of the Edgárdia Farm belongs to the College of Agronomicas Ciencias/UNESP, city of Botucatu - SP. The program used for the attainment of the morphometrical variable was the ILWIS 3.2 version and the topographical letter of the IBGE with 1:50.000 scale. In the study of biodiversity four transects in the micro watershed had been installed, in the parts high (superior third), medium high and medium low (medium third) and low (inferior third) of the micro watershed, in which parcels of 10 x 5 meters had been installed. In the four transects, the forest species had been quantified and commanded in popular and classified families, species, names in its respective ecological successions (pioneer, secondary or climax). It was measured in each tree the height and the diameter in the height of the chest (DAP). The morphometrical variable and the results were: area of 7,205 kmø; perimeter of 11,59 km; length and width of micro watershed 3,578 the equal 3,016 km; length of the draining net and quotas of 15,68 km and 1100,00 km; factor of form 0,79, considered very high; density of draining of 2,18 km.kmø, classified as average; the high declivity of 76,98%, in accordance with the classes of declivities and types of relief of the micro watershed, was classified as scarped; frequency of rivers the 3,19 segments of rivers...

This conflict is materialized by means of the practice known as biopiracy, which involves as much the genetic resource as the knowledge related to the mentioned resource, damaging mostly countries like Brazil. With the ratification of the Convention of Biological Diversity in 1994 and the edition of the legislation MP nº 2.186-16 in 2001, Brazil regulated affairs that involve the traditional knowledge related to genetic resource. But will this legislation take into account the interests of traditional populations? With the aim to analyse the applicability of Brazilian legislation which regulates the acess to traditional knowledge related to genetic resource of two native populations who inhabit the surroundings of Benjamin Constant city, located in the region of High Solimões River, in Amazonas, Brazil, one denominated Aldeia Kokama, of Kokama ethnic group, and the other Native community of Novo Paraíso, of Ticuna ethnic group. This research founded on the Sociological concept of Law, developed by Bourdieu (1989), and as logical sustainability the systemic abordage of Morin (2002), and employing the case study methodology, more specifically of two cases: the legislation and the human group. Thus, with the development of the research, it was been observed that Brazilian legislation, the MP nº 2.186-16, presents conceptual inaccuration and lack of practicability. With regard to the native populations of Nova Aliança and of Novo Paraíso, it was observed that these human groups develop a relation of community and live daily in an environment little modified in a region of Amazonian Forest which contains high concentration of biodiversity, demonstrating a great knowledge on the genetic resources that sorround them. Nevertheless, their lack of information and of legislative knowledge render impossible the application of such legislation rules and, consequently, the demand of their rights. The analysis of Brazilian legislation which regulates the acess to traditional knowledge related to genetic resource and of the native populations of Nova Aliança and of Novo Paraíso showed the correspondence between both, but with sorrowful confirmation of the inapplicability of the legislation for these people, caused mainly by the lack of information they showed regarding the rights due to them. / Com o dilema internacional formado, de um lado os países detentores de tecnologia, apoiados nos dispositivos do Acordo sobre Aspectos dos Direitos de Propriedade Intelectual Relacionados com o Comércio (TRIPS), da Organização Mundial do Comércio (OMC), para garantir que os recursos genéticos sejam considerados patrimônio comum da humanidade, e de outro os países de origem de recursos genéticos, agarrados à Convenção sobre Diversidade Biológica (CDB), baseada no princípio de soberania dos Estados para explorar seus próprios recursos, o Direito torna-se de fundamental importância na intermediação de interesses tão antagônicos. Esse conflito é materializado pela prática conhecida como biopirataria, a qual engloba tanto o recurso genético propriamente dito como o conhecimento que o envolve e, por isso, atinge sobremaneira países como o Brasil. Com a ratificação da CDB em 1994 e a edição da MP nº 2.186-16 em 2001, o Brasil regulamentou questões que envolvem o conhecimento tradicional associado ao recurso genético. Mas será que essa legislação mantém correspondência com os interesses das populações tradicionais? Com o intuito de analisar a aplicabilidade da legislação brasileira que regulamenta o acesso ao conhecimento tradicional associado ao recurso genético em duas populações indígenas localizadas no município de Benjamin Constant, região do Alto Solimões do estado do Amazonas, autodenominadas Aldeia Kokama Nova Aliança, de etnia kokama, e Comunidade Indígena Novo Paraíso, de etnia tikuna, utilizamos como base teórica desta pesquisa o conceito sociológico de Direito desenvolvido por Bourdieu (1989) e como sustentabilidade lógica a abordagem sistêmica de Morin (2002), tendo sido empregada a metodologia estudo de caso, mais especificamente de dois casos: a legislação e o grupo humano. Nesse sentido, com o desenvolvimento do estudo, pode-se dizer que a legislação brasileira, aqui representada pela MP nº 2.186-16, apresenta imprecisão conceitual e falta de executividade. No que tange às populações indígenas de Nova Aliança e de Novo Paraíso, afirma-se que são grupos humanos que transmitem uma relação de coletividade e por conviverem diariamente com um ambiente natural pouco modificado, em uma zona da F loresta Amazônica de alta concentração de biodiversidade, demonstram ter um grande conhecimento sobre os recursos genéticos que os cercam. No entanto, a falta de informação e preparação legislativa desses povos impossibilita a aplicação de tais normas e, conseqüentemente, a exigência de seus direitos. A análise da legislação brasileira que regulamenta o acesso ao conhecimento tradicional associado ao recurso genético e das populações indígenas de Nova Aliança e de Novo Paraíso demonstrou correspondência entre ambas, mas com a triste constatação de negativa de aplicabilidade da legislação a esses povos, ocasionada principalmente pela falta de informação que evidenciaram quanto aos direitos assegurados a eles

The riparian zone is a changeable and species-rich habitat with important ecological functions that have long been affected by human activities such as hydropower and forestry. Rivers and their adjacent riparian zones also constitute a transport route for plant parts and seeds in a form of passive transport, called hydrochory, which can contribute to the establishment of plants or the preservation of diversity in the riparian zone. Theories such as "the river collector hypothesis" state that the diversity of plants increases with distance from the source of a river and this study aims to investigate a specific part of this theory, namely the effect of tributaries on the accumulation of plants in the riparian zone. Plant surveys have been carried out upstream and downstream of the outlets of several tributaries to Vindelälven (unregulated) and Umeälven (regulated) in Västerbotten County, Sweden, to compare these locations with each other. Species numbers and effective species numbers for upstream and downstream surveys were analysed using paired t-tests with the expectation that both species numbers and effective species numbers would be higher downstream of tributaries than upstream. The results showed no significant differences between the upstream and downstream inventories. When examining the data, there was an indication of a trend of higher species numbers and effective species numbers downstream of tributaries in the Umeälven, but further research is needed to investigate possible connections. The explanation of the effect of tributaries on the diversity of plants in the riparian zone may be more complicated than can be explained only by theories of the accumulation of plants from hydrochory. Alternatively, the effect from the tributaries is small in relation to the longitudinal build-up of plants that occurs in longer free-flowing stretches of the rivers, which may hide the effect of the tributaries. / Strandzonen är ett föränderligt och artrikt habitat med viktiga ekologiska funktioner som under lång tid har påverkats av mänskliga verksamheter som vattenkraft och skogsbruk. Älvar och dess angränsande strandzoner utgör även en transportsträcka för växtdelar och fröer i en form av passiv transport, benämnd hydrochori, som kan bidra till etableringen av växter eller bevarandet av mångfalden i strandzonen. Teorier som ”the river collector hypothesis” säger att mångfalden av växter ökar med avstånd från källan i en älv och den här studien har som mål att undersöka en specifik del av denna teori, nämligen vilken effekt biflöden har på ansamlingen av växter i strandzonen. Växtinventeringar har genomförts uppströms och nedströms om flera biflödens utlopp till Vindelälven (oreglerad) och Umeälven (reglerad) i Västerbottens län för att jämföra dessa lokaler med varandra. Artantal och effektivt artantal för uppströms- och nedströmsinventeringar analyserades med parade t-tester med förväntningen att både artantalet och det effektiva artantalet skulle vara större nedströms om biflöden än uppströms. Resultaten visade inga signifikanta skillnader mellan uppströms- och nedströmsinventeringarna. Vid granskning av data fanns en antydan till en trend med större artantal och effektivt artantal nedströms om biflöden i Umeälven men ytterligare undersökningar behövs för att utreda eventuella samband. Förklaringen till vilken effekt biflöden har på mångfalden av växter i strandzonen kan vara mer komplicerad än att det på egen hand kan förklaras med teorier om ansamling av växter från hydrochori. Alternativt är effekten från biflödena liten i relation till den longitudinella uppbyggnaden av växter som sker i längre fritt flödande sträckor av älvarna vilket skulle kunna dölja biflödenas effekt.
