O tempo geológico nas narrativas de museus de história natural: uma análise comparativa / The Geological Time in Natural History Museum\'s narrative: a comparative analysis

Rebeca Ribeiro Bombonato 30 August 2016 (has links)
Esta pesquisa visa analisar a utilização do tema \"Tempo Geológico\" nas narrativas de museus de História Natural através da análise de exposições em museus em quatro países: Alemanha, o Museum für Naturkunde de Berlim; Inglaterra, o Natural History Museum, em Londres; França, o Muséum National d\'Histoire Naturelle de Paris; Brasil, o Museu de Ciências Naturais e Museu de Ciência e Tecnologia, ambos em Porto Alegre. Foram analisadas três exposições no museu em Berlim: \"Mundo dos Dinossauros\" (Saurierwelt), \"Cosmos e o Sistema Solar\" (Kosmos und Sonnesystem) e \"Evolução em Ação\" (Evoluion in Aktion). No museu de Londres, foi estudada uma exposição na zona vermelha, \"Desde o Início\" (From the beginning). No museu francês, duas galerias foram estudadas, a Grande Galerie d\'Evolution and a Galerie d\'Anatomie comparée et Paléontologie. A primeira Galeria, a exposição \"Evolução da vida\" (L\'evolução de la vie) foi estudada, enquanto na Galeria de Paleontologia, foram analisadas as exposições \"Os Vertebrados\" (Les Vertèbres) e \"Os Invertebrados\" (Les Invertébrès). No Museu de Ciências Naturais em Porto Alegre, a exposição permanente foi explorada, em que a evolução da vida na Terra é o foco. Quanto ao Museu de Ciência e Tecnologia, foram analisadas as exposições \"Planeta Terra\" e \"Milhões de Anos\". É proposta uma análise qualitativa utilizando os dados da documentação literatura e disponíveis, bem como registos das exposições. Museus de História Natural tem um papel importante como instituições de extensão, apresentando os processos naturais da Terra. O Tempo Geológico é uma ferramenta chave para esse entendimento. O objetivo da presente pesquisa é comparar diferentes exposições (sua forma, organização e narrativas) para avaliar a abordagem de Tempo Geológico e também o seu potencial de integração normalmente tratados como áreas separadas em instituições de História Natural: Ciências da Terra e ciências da vida. / This research seeks to examine how the theme \"Geological Time\" is addressed in the narratives of Natural History Museums through the analysis of exhibits in museums in four countries: Germany, the Museum für Naturkunde in Berlin; England, the Natural History Museum in London; France, the Muséum National d\'Histoire naturelle in Paris; Brazil, the Museu de Ciências Naturais and the Museu de Ciência e Tecnologia, both in Porto Alegre. The authors analysed three exhibits in the museum in Berlin: Saurierwelt (World of Dinosaurs), Kosmos und Sonnesystem (Cosmos and the Solar System) and Evolution in Aktion (Evolution in Action). In the museum in London, the authors studied one exhibit in the red zone, From the beginning. In the French museum, two galleries were studied, the Grand Galerie d\'Evolution and the Galerie d\'Anatomie comparée et Paléontologie. From the first Gallery, the exhibit L\'evolution de la vie (Evolution of life) was studied, while in the Paleontology Gallery the exhibits Les vertébrès (The vertebrates) and Les invertébrès (The invertebrates) were analysed. In the Museu de Ciencias Naturais in Porto Alegre, the permanent exhibit was explored, in which the evolution of life on Earth is the focus. As for the Museu de Ciência e Tecnologia, the Paleontology exhibit was analysed. We propose a qualitative analysis using data from the literature and available documentation as well as records of the exhibitions. Natural History Museums have an important role as outreach institutions presenting the natural processes on Earth. The Geological Time is a key tool for this understanding. The goal of the present research is to compare the exhibits (its form, organization and narratives) in three of the most traditional European Natural History Museums with two Brazilian ones. We aim to evaluate the approach of geological time and also its potential for integrating usually treated as separate areas in natural history institutions: Earth sciences and life sciences.

História natural das aves em um parque urbano no Sudeste do Brasil / Natural history of the birds at urban park in a Southeastern Brazil

D'Angelo, Giulia Bagarolli, 1982- 03 December 2014 (has links)
Orientador: Ivan Sazima / Dissertação (mestrado) - Universidade Estadual de Campinas, Instituto de Biologia / Made available in DSpace on 2018-08-24T19:31:06Z (GMT). No. of bitstreams: 1 D'Angelo_GiuliaBagarolli_M.pdf: 26225858 bytes, checksum: a6b9b77b3bd66a3d80fd5d3157a3fef5 (MD5) Previous issue date: 2014 / Resumo: O processo de urbanização no Brasil aumenta rapidamente e as áreas verdes fornecem refúgio para a fauna local, na qual as aves são o elemento mais evidente. Aves são agentes importantes de dispersão e polinização, controle de pragas, além de ciclagem de nutrientes e adubação do solo, exercendo diversos serviços ambientais. Embora essas funções possam ser vistas como tendo pouca importância no ambiente urbano, aves apresentam grande mobilidade, o que significa que suas funções podem ser transportadas de uma área verde para outra. Estudamos a história natural das aves em um parque urbano em Campinas, São Paulo. Alimentação, reprodução e repouso foram os focos deste estudo, além de outras atividades como higiene e conforto. As atividades alimentares que observamos seguem, em linhas gerais, o que está relatado na literatura sobre aves brasileiras. Entretanto, observamos alguns fenômenos não relatados ou pouco conhecidos Associações alimentares de aves piscívoras seguindo lontras em atividade de caça não estavam relatadas para América do Sul. Disputa por área de caça entre fêmeas de biguatinga Anhinga anhinga foi outra novidade relacionada à atividade alimentar, assim como a predação de um bivalve asiático invasor por aves aquáticas. A inclusão de uma categoria de presa (répteis) na dieta do sabiá Turdus leucomelas também representou uma novidade. As atividades reprodutivas que observamos no parque também seguem, em linhas gerais, as informações disponíveis na literatura sobre aves brasileiras. Todavia, observamos eventos pouco conhecidos ou não relatados na literatura. A corte do urubu Coragyps atratus está relatada para a América do Norte apenas. Também pouco conhecida é a disputa territorial "simbólica" entre fêmeas do pica-pau Colaptes melanochloros, comportamento relatado para machos de outras espécies. Outra novidade foi a pressão de predação pelo lagarto Salvator merianae em ninhos de aves que nidificam no chão ou em vegetação próxima a margem de lagoa. Atividades de higiene e conforto são bem conhecidas e ilustradas na literatura e acreditamos que não tenhamos observado algum comportamento de higiene e conforto que não esteja relatado, ainda que de passagem, para as aves brasileiras. Estudos sobre história natural de aves proporcionam um conhecimento mais adequado das relações entre as aves, o ambiente urbano e a população humana. Em parques e áreas verdes, as aves representam uma parcela de lazer para a população urbana. O número de observadores de aves aumenta no Brasil e, paralelamente, há uma valorização da conservação ambiental. Portanto, estudos em parques urbanos resultam em conhecimento sobre a avifauna, além de valorizar as áreas verdes e popularizar o conhecimento sobre as aves e a sua importância biológica / Abstract: The urbanization process in Brazil is quickly changing the landscape and so called green areas provide refuge for the local fauna, of which birds are the most conspicuous part. Birds are important agents of plant dispersal and pollination, pest control, as well as nutrient cycling and soil fertilizing, which result in ecosystem services. Although these functions may be viewed as having little or no importance in the urban landscape, birds are highly mobile and their functions may connect several green areas. We studied the natural history of birds in an urban park in Campinas, São Paulo, Southeastern Brazil. We focused on feeding, reproducing, and resting, besides preening and comfort activities. In general, feeding activities we observed followed what is published about Brazilian birds. However, we observed a few little known or until recently unpublished events. Feeding associations of piscivorous birds following foraging otters were unreported for South America. Contests for hunting area between females of the darter Anhinga anhinga was another novelty related to feeding activity, as well as the predation of an Asiatic invasive clam by water birds. Predation of reptiles by the thrush Turdus leucomelas was also a novelty. In general, reproductive activities we observed followed what is published for Brazilian birds. However, we observed a few little known or unpublished behaviors. For example the courtship of the vulture Coragyps atratus is reported for the North America only. Also little known is the territorial "symbolic" contest between females of the woodpecker Colaptes melanochloros, a behavior reported for males of other species. Another novelty was the predation pressure on birds that nest on the ground or bank vegetation by the large lizard Salvator merianae. Preening and comfort behaviors are well known and illustrated in literature and we believe that we did not record any behavior that is not reported in the literature on Brazilian birds, even if en passant. Studies on natural history of birds provide a better knowledge on the relationships between the birds, the urban landscape, and the human population. In urban parks and green areas, birds are part of leisure activities for urban people. The number of birdwatchers is increasing in Brazil and, at the same time, there is a growing awareness of environment conservation among people who are in contact with nature. Therefore, studies on natural history of birds in urban parks and other green areas result in knowledge of the bird fauna, besides increasing the intrinsic value of these environments and making available details of the life of birds and their biological significance / Mestrado / Biodiversidade Animal / Mestra em Biologia Animal

The forgotten beasts in medieval Britain : a study of extinct fauna in medieval sources

Raye, Lee January 2016 (has links)
This thesis identifies and discusses historical and literary sources describing four species in the process of reintroduction: lynx (Lynx lynx), large whale (esp. Eubalena glacialis), beaver (Castor fiber) and crane (Grus grus). The scope includes medieval and early modern texts in English, Latin, and Welsh written in Britain before the species went extinct. The aims for each species are: (i) to reconstruct the medieval cultural memory; (ii) to contribute a cohesive extinction narrative; and (iii) to catalogue and provide an eco-sensitive reading of the main historical and literary references. Each chapter focuses on a different species: 1. The chapter on lynxes examines some new early references to the lynx and argues that the species became extinct in south Britain c.900 AD. Some hard-to-reconcile seventeenth century Scottish accounts are also explored. 2. The chapter on whales attributes the beginning of whale hunting to the ninth century in Britain, corresponding with the fish event horizon; but suggests a professional whaling industry only existed from the late medieval period. 3. The chapter on beavers identifies extinction dates based on the increasingly confused literary references to the beaver after c.1300 in south Britain and after c.1600 in Scotland, and the increase in fur importation. 4. The chapter on cranes emphasises the mixed perception of the crane throughout the medieval and early modern period. Cranes were simultaneously depicted as courtly falconers’ birds, greedy gluttons, and vigilant soldiers. More generally, the thesis considers the levels of reliability between eyewitness accounts and animal metaphors. It examines the process of ‘redelimitation’ which is triggered by population decline, whereby nomenclature and concepts attached to one species become transferred to another. Finally, it emphasises geographical determinism: species generally become extinct in south Britain centuries before Scotland.

'n Benadering vir die realisering van omgewingsopvoeding in die algemene wetenskap sillabus van graad sewe tot nege

Uys, Dirk Pieter. 13 August 2012 (has links)
D.Ed. / Man is dependant on the environment for his essential requirements and welfare. In the current technological era our world is being irreversibly damaged through the lack of long term vision, due mainly to ignorance of the surroundings man finds himself in. This research focuses on the feasibility of Environmental Education as a perspective on the content of General Science of the compulsory school phase. The researcher feels confident that Environmental Education would indeed add a positive dimension to the future teaching of General Science. The researcher points out that Environmental Education is essential to future generations. Research is directed towards the attainability of Environmental Education in formal Education. A new-found demand faces the General Science teacher. The researcher points out that change is irrevocably due to the technological advances and development together with the adjoining dynamic expectations and demands of society. Mankind's and environment's history has clearly shown that the environment is secondary to progress. The environment must satisfy man's ever growing demands. The contrary hasn't been proven up to date. Man is insensitive to and ignorant about the demands of the environment. The corruption of a once healthy interaction between man and environment is unfortudately a result of man's impetance, insensitivity and ignorance of the environment. Therefore man must take the initiative to restore the environment to a sustainable system where man and his environment can flourish. This research proves a lack of legislation in the necessary nationwide Environmental Education. Environmental Education is far removed from its rightful place in education, not featuring in General Science but through the inclusion of the biophysical surroundings. General Science finds its roots in the biophysical dimension of the environment. The researcher has found that the total environment is only casually referred to in its political, economical and social dimensions.

The pursuit of nature : defining natural histories in eighteenth-century Britain

Gibson, Susannah January 2012 (has links)
Many histories of natural history see it as a descriptive science, as a clear forerunner to modern studies of classification, ecology and allied sciences. But this thesis argues that the story of unproblematic progression from eighteenth-century natural history to nineteenth-century and modern natural history is a myth. Eighteenth-century natural history was a distinct blend of practices and theories that no longer exists, though many individual elements of it have survived. The natural history that I discuss was not solely about collecting, displaying, naming and grouping objects. Though these activities played an important part in natural history (and in many histories of natural history) this thesis focuses on some other key elements of natural history that are too often neglected: elements such as experimenting, theorising, hypothesising, seeking causes, and explaining. Usually these activities are linked to natural philosophy rather than natural history, but I show how they were used by naturalists and, by extension, create a new way of understanding how eighteenth-century natural history, natural philosophy and other sciences were related. The first chapter is about the end of eighteenth-century natural history and looks at the role of the Linnean Society of London. It argues that this society tried to homogenise British natural history through the promotion of the Linnean sexual system of plant classification and through the suppression of the kinds of experimental and theoretical work described in this thesis. To understand that experimental and theoretical work, and to see what British natural history really entailed in this period, three central chapters focus on specific case studies. The second chapter shows how English-based naturalists such as John Ellis (1710-1776) approached the problem of distinguishing plants from animals, and especially about how they used chemical experiments to decide whether things such as coral and corallines should be placed in the animal or plant kingdom. The third chapter discusses sensitive plants and the overlaps between natural history and natural philosophy. It draws on case studies of naturalists who investigated things like plant motion and apparent plant sensitivity with different observational and experimental methods, and tried to explain them using various mechanical and vitalist explanations. The fourth chapter focuses on the controversy over whether plants (like animals) can be male or female and shows the theoretical and experimental tools that naturalists used to address this issue. Together, these chapters give a very detailed insight into the everyday practices and theories used by eighteenth-century naturalists and show the variety of activities that made up the field. The next two chapters focus on the identity and interactions of naturalists and show how they created a distinctive science: the fifth chapter is about how someone in England could go about becoming an authority on natural history in the late eighteenth century; and the final chapter looks outwards from Britain and examines how British natural history influenced, and was influenced by, European natural history; it uses correspondence to examine how British naturalists communicated with their overseas counterparts and what each party gained from those exchanges.

A reinterpretation of the small Captorhinid Reptile Captorhinikos Parvus Olson as a new genus, reanalysis of its cranial anatomy, and a phylogenetic analysis of the basal reptilian family Captorhinidae

Albright, Gavan McBride 01 January 2003 (has links)
The cranial anatomy of the basal captorhinid reptile Captorhinikos parvus (Reptilia, Captorhinidae), is reinterpreted here based on analysis of a group of new specimens recovered subsequent to its original diagnosis as well as further analysis of the original specimens utilized in E.C. Olson's original characterization of the species. Structural features inconsistent with the generic description suggest the redefinition of C. parvus as a new genus, Rhodotheratus parvus. Analyses of basal members and selected derived members support the characterization of Rhodotheratus as a distinct taxon.

The Biogeographic Distribution of Caddisflies (Insecta: Trichoptera) within the South-Central United States

Perry, Heather Ann 05 1900 (has links)
Through the use of natural history records, published literature, and personal sampling (2011-2016) a total of 454 caddisfly species represented by 24 families and 93 genera were documented from the south-central United States. Two Hydroptilidae species were collected during the 2011-2016 collection efforts that are new to the region: Hydroptilia scheringi and Mayatrichia tuscaloosa. Eightteen species are endemic and 30 are considered species of concern by either federal or state agencies. The majority of each of these groups is Hydroptilidae, or microcaddisflies. Trichoptera community structure, by minimum number of species, was analysed in conjunction with large-scale geographical factors to determine which factor illustrated caddisfly community structure across the region. Physiographic provinces compared to other geographic factors analyzed best-represented caddisfly communities with a minimum of 10 or more species. Statistically, Hydrologic Unit Code 4 (HUC 4) was the most significant geographical factor but low number of samples representing this variable rendered it less representative of caddisfly community structure for the study area.

Navajo Baskets and the American Indian Voice: Searching for the Contemporary Native American in the Trading Post, the Natural History Museum, and the Fine Art Museum

Howe, Laura Paulsen 18 July 2007 (has links) (PDF)
This thesis examines the display of Navajo baskets and examines some of the possible meanings Navajo baskets can reveal. Acknowledging that the meaning of a work of art changes when it is placed in different environments, the thesis explores what meanings are revealed and what meanings are concealed in basket displays in three venues: the trading post, the natural history museum, and the fine art museum. The study concludes that the fine art museum has the most potential to foster a dialogue about the contemporary Navajo, whose identity is a product of continuity and change. Chapter one discusses the basket's connotation as one of continuity and change, a meaning essential to understanding the contemporary Navajo. It becomes clear that when looking for the meaning of tradition and adaptation, the institutional utterance of an exhibition venue must be one that allows a complex modern Navajo identity to emerge. Chapter two examines the institutional utterance of the trading post. In such a setting, meanings of a mythical past emerge from the basket. The environment of the trading post reveals a romantic view of the Old West that hides the meaning of the contemporary Navajo from patrons and viewers. Chapter three focuses on the natural history museum and the effects of its institutional utterance on the Navajo basket's significance. In this learning environment, the Navajo basket acts as an artifact and meanings emerge about Navajo ritual and history. However, natural history museums often educate audiences through means like curiosity cabinets and living history displays that distance the contemporary Navajo. It is the fine art museum that has the most potential to reveal the adaptive, contemporary Navajo, discussed in chapter four. Art museums validate baskets as art objects when they exhibit them with Western painting and sculpture. Such displays can hide the contemporary Navajo in a discussion of formal elements. However, when an art museum exhibits a basket as a meaningful object, it allows the basket to reveal the Dine's desire for cultural continuity and the long Navajo history of adapting to changing environments.
