RESUMEN

This study investigates nineteenth century natural history practices through the lens of the Actor-Network Theory, which posits that scientific practice is shaped by an intricate network of interactions between human and non-human actors. At the core of this research is the analysis of correspondence between Charles Darwin and his collaborators during the Cirripedia Project, which unveils a complex landscape of negotiations with illustrators, funders, specimen owners, and translators, among other stakeholders and interested parties. The study goes beyond the final outcomes of scientific research, delving into behind-the-scenes interactions, and hidden constructions, shedding light on the complex dynamics and actors that conventional scientific narratives often overlook. In general, this approach provides a detailed and insightful view of the underlying processes of nineteenth-century scientific practice, underscoring the importance of epistolary correspondence as a central element in producing scientific knowledge at the time, and in particular it reveals to us how much Darwin was himself involved in the production of his famous work on barnacles. By emphasizing the intricacies of research, this study enriches our understanding of Darwin's work as well as natural history practices in the 19th century, highlighting the complexity and diversity of actors and agents involved in shaping scientific knowledge.

RESUMEN

By the mid-seventeenth century, images of natural elements that originated in Dutch Brazil circulated in Europe. These were often included in art collections (the Libri Picturati) and natural history treatises (the Historia Naturalis Brasiliae and the India Utriesque re Naturale et Medica, 1658). The plant woodcut images in these books constituted (icono) type specimens and played a significant role in disseminating scientific botanical knowledge. We present a systematic analysis of their origins by cross-referencing the visual and textual sources related to Dutch Brazil. To do so, we used our previous botanical identifications of the portrayed plants, published sources, and digital archival material. The plant woodcuts accounted for 529 images, which corresponded to 426 taxa. We created a PDF booklet to visualize the (dis-) similarities of the woodcuts with the Libri Picturati and other visual sources. Substantial differences in the visual-making methodology exist between the two treatises (1648, 1658). In the first book, most of the images were available from Dutch Brazil and carved into the woodcuts, while most of these woodcuts were reused in the second one. The Indigenous Tupi-based plant names accompanying the images were crucial when arranging the sources, and portraying as much botanical information as possible was commonly the goal. Freshly picked, living plants, dried branches, fruits, and seeds were used to represent the megadiverse Brazilian flora, even when these belonged to species originating from other regions. Despite not being recognized for their contribution, Indigenous Brazilians and enslaved Africans were essential in the visual knowledge-making processes that later resulted in these natural history collections. As several sources remain lost and many histories yet untold, further archival studies and collaborative projects are pertinent to reveal the missing pieces of this conundrum.

RESUMEN

The long 19th century was a period of many developments and technical innovations in agriculture and animal biology, during which actors sought to incorporate new practices in light of new information. By the middle of the century, however, while heredity steadily became the dominant concept in animal husbandry, some policies related to livestock improvement in Brazil seemed to have been tailored following a climate-deterministic concept established in the mid-18th century by the French naturalist Georges-Louis Leclerc, the Comte de Buffon. His theory of animal degeneration posited, among other things, the necessity of recurrent crossbreeding to preserve animal species living in nonnative environments from climate-induced degeneration. Although largely discredited by the early 19th century, the teachings of the French naturalist seem to have found supporters in a Brazilian program to modernize national agriculture through the application of the natural sciences. Herein I examine the revival of Buffon's theories in that government-sponsored program to improve animal husbandry and breeding techniques, including actual applications of this theory in the real world. Ultimately, I argue that Buffon's theory of degeneration was used to tailor public policies and funding for the improvement of domesticated animals in Brazil between 1856 and 1860.

RESUMEN

BACKGROUND: This work reunites many women naturalists who registered knowledge about native flora in scientific expeditions around the globe between the seventeenth and nineteenth centuries. Since male naturalists are more recognized in this period of time, we aimed to list female naturalists that published plant descriptions and observations, focusing on the work of Maria Sibylla Merian and to analyze her trajectory as an example to discuss the patterns of the suppression of women scientists. A second aim was to inventory the useful plants described in Maria Sibylla's Metamorphosis Insectorum Surinamensium and find pharmacological evidence about the traditional uses described for those plants cited as medicinal and toxic. METHODS: A survey of female naturalists was carried out by searching information in Pubmed, Scielo, Google Scholar and Virtual Health Library. Once Maria Sibylla published her book Metamorphosis Insectorum Surinamensium by her own, without male co-authors, and also this book is one of the only to have text and illustrations altogether and there are reports indicating information on useful plants in this work, she and her book were chosen as subject of this research. All the information was tabulated by dividing the plants into food, medicinal, toxic, aromatic or other uses. Finally, with the combinations of the scientific name of medicinal and toxic plants with information about their popular uses, a search was carried out in databases in order to indicate current pharmacological studies that reported evidences about the traditional uses described. RESULTS: We found 28 women naturalists who participated in scientific expeditions or trips, or in a curiosity cabinet, or who were collectors of Natural History between the seventeenth and nineteenth centuries. All these women illustrated botanical species and/or recorded their everyday or medicinal use or reported their observations in the form of a published work, letters or diaries. Also, the trajectory of Maria Sibylla Merian revealed that her scientific relevance has been neglected from the eighteenth century by mechanisms of suppression, most of the time by male depreciation, which can be seen as a pattern for suppression of women in science. However, Maria Sibyllas' contributions have been valued again in the twenty-first century. In Maria Sibylla's work, 54 plants were identified, 26 of them used for food, 4 of them aromatic, 8 medicinal, 4 toxic and 9 other uses. CONCLUSION: This study evidences that there are female naturalists whose work could be an important source for ethnopharmacological studies. Researching about women scientists, talking about them and highlighting the gender bias present in the scientific academy about the way the history of science is told is essential for the construction of a more diverse and richer scientific academy. The traditional use of 7 of 8 medicinal plants and 3 of 4 toxic plants reported was correlated with pharmacological studies, highlighting the importance of this historical record and its potential to direct strategic research in traditional medicine.

RESUMEN

Francisco Antônio de Sampaio worked as a surgeon for over two decades in Cachoeira, in the captaincy of Bahia, Brazil. In this village, he produced writings on natural history, which he sent to the Lisbon Academy of Science, although he had no specific training in this area. This article analyzes his scientific output and healing practices, especially the uses and descriptions of local plants and his relationships with different agents, such as the "local commoners" and the naturalist and magistrate Joaquim de Amorim e Castro. His production of knowledge is interpreted here both from the perspective of the construction of scientific authority and through his interactions with local and metropolitan agents.

Francisco Antônio de Sampaio atuou como cirurgião por mais de duas décadas em Cachoeira (BA). Nessa vila, produziu e enviou à Academia das Ciências de Lisboa escritos de história natural, embora não tivesse formação específica para esses estudos. Neste artigo analisamos sua produção científica e suas práticas de cura, em particular os usos e descrições das plantas locais e sua relação com diferentes agentes, a exemplo das pessoas do "vulgo local" e do naturalista e juiz de fora Amorim e Castro. Buscamos interpretar sua produção de conhecimento, tanto do ponto de vista da construção de autoridade científica quanto de sua interação com os agentes locais e metropolitanos.

RESUMEN

From records on plants and herbs made by doctors, healers, missionaries, and colonial administrators in the seventeenth and eighteenth centuries, this article explores ways of constructing knowledge about flora using the concept of circulation proposed by Kapil Raj. The distinct experiences and documents analyzed demonstrate the process of observing, collecting, systematizing, and circulating knowledge, and the influence of natural history and the Hippocratic tradition on the classification of herbs and plants and on the descriptions adopted in these texts. From printed books to notes scattered through travel diaries, usefulness of these species to humankind was the element valued by those who directly observed the potential of American plants, fruits, and herbs.

A partir dos registros sobre plantas e ervas de médicos, agentes de cura, missionários, administradores coloniais nos séculos XVII e XVIII, o artigo explora as formas de construção do conhecimento sobre a flora, utilizando o conceito de circulação proposto por Kapil Raj. As experiências distintas e os documentos analisados demonstram o processo de observação, coleta, sistematização e circulação do conhecimento e a influência da história natural e da tradição hipocrática na classificação das ervas e plantas e na descrição adotada nos textos reunidos neste artigo. Desde livros impressos até anotações dispersas em diários de viagens, os usos das espécies para a vida humana foi o elemento valorizado por aqueles que observaram diretamente o potencial de plantas, frutos e ervas americanas.

RESUMEN

The article intends to contribute to the history of science, indigenous history and the history of Portuguese America. We begin with the methodological assumptions of Dominique Pestre and the historiography on Portuguese America to investigate a network of indigenous settlements, the work of civil servants with naturalist knowledge, the shipment of botanical species for analysis in Portugal and, finally, the foundation of a botanical garden in the captaincy of Guayases (Goiás) from 1772 to 1806. We describe the indigenous contribution to the construction of natural history knowledge, and discuss the influence of Enlightenment concepts on the reform of the Portuguese colonial system in the captaincy based on Portuguese administrative documentation, letters and study of the application of laws and instructions.

O artigo pretende contribuir com a história das ciências, a história indígena e a história da América portuguesa. Parte-se dos pressupostos metodológicos de Dominique Pestre e da historiografia sobre a América portuguesa para interrogar a existência de uma rede de aldeamentos indígenas, a atuação de funcionários com saberes naturalistas, o envio de espécies botânicas para análise em Portugal e, por fim, a fundação de um horto botânico na capitania de Guayases (Goiás) entre 1772 e 1806. Apresenta-se a contribuição indígena na construção dos conhecimentos da história natural e discutem-se as influências de concepções da Ilustração na reforma do sistema colonial português na capitania a partir de documentação administrativa portuguesa, cartas e do estudo da aplicação de leis e instruções.

RESUMEN

More than a century ago, Edward W. Nelson and Edward A. Goldman spent 14 years (1892-1906) traveling across much of Mexico in one of the most critical biological expeditions ever undertaken by two naturalists. This long-term survey was a cornerstone in Mexican mammalogy development; however, their specific role in discovering taxa that were practically unknown before the expedition is not yet necessarily recognized. In a time when the historical aspect of knowledge on mammals is being ignored for the new generations of mammalogists, a detailed analysis of the legacy of the survey is essential. Here I focus on shrews (Eulipotyphla, Soricidae) to analyze how the fieldwork and the specimens they collected have contributed to the current knowledge of shrews in the country. Nelson and Goldman collected 474 specimens of shrews, representing 31 of the 40 species that have currently been recognized. This collection has been key to building taxonomic, evolutionary, and biogeographic knowledge of shrews in the country. The success of the expedition was primarily due to the epistemic role of novel methods and approaches in natural history research at the time. The collection also offers the opportunity to document the loss of species and ecological interactions as indirect consequences of human activities, especially in montane regions. I argue that the value of this expedition can still increase with the use of modern biodiversity study tools and the digitization and access of ancient material such as photographs, field notes, and correspondence.

RESUMEN

This paper is intended as a contribution to the study of science and religion in late modern Catholic societies. I explore the treatment of natural philosophy vis-à-vis religious (Roman Catholic) authority, the teaching of Biblical geology, and the use of natural theology in texts from Río de la Plata in the transition from late colonial to early independent times (1770-1815). After reviewing the assimilation of modern science into scholastic teaching and the articulation of reason and religious authority, the article considers the handling of the early history of the Earth in the theses of scholastic teachers and in the geological memoirs of the naturalist priest from Montevideo Dámaso Larrañaga. The core of the paper is devoted to the treatment of natural theology in Larrañaga's Diary of Natural History and in the speeches and documents of enlightened crown bureaucrats. The conclusion is reached that the harmonious character of the relationships between science and religion in this period and location harboured tensions (such as the blurred frontier between natural theology and natural religion) which could be accounted for in terms of the inherent inconsistencies in the programme of Catholic Enlightenment.

RESUMEN

Several problems with Hegel's conception of the organism in the Encyclopaedia are due to the separation between individual life in Nature and the universal life of the Concept. This discontinuity between ontogenesis and phylogenesis in his dialectics of organic life will be studied here by following his presentation of physiological development, especially reproduction, and by reconstructing the historical model he criticizes-Leibniz's organic machines and their development in Buffon's Natural History-a model that was also of crucial importance to the philosophy of nature of Schelling and his followers.

RESUMEN

This paper analyzes biological and scientific discourses about the racial composition of the Brazilian population, between 1832 and 1911. The first of these dates represents Darwin's first arrival in the South-American country during his voyage on H.M.S. Beagle. The study ends in 1911, with the celebration of the First universal Races congress in London, where the Brazilian physical anthropologist J.B. Lacerda predicted the complete extinction of black Brazilians by the year 2012. Contemporary European and North-American racial theories had a profound influence in Brazilian scientific debates on race and miscegenation. These debates also reflected a wider political and cultural concern, shared by most Brazilian scholars, about the future of the Nation. With few known exceptions, Brazilian evolutionists, medical doctors, physical anthropologists, and naturalists, considered that the racial composition of the population was a handicap to the commonly shared nationalistic goal of creating a modern and progressive Brazilian Republic.

RESUMEN

During the nineteenth century, scientific expeditions travelled across Brazil investigating its fauna, flora and natural geological resources. By examining letters, reports, travelogues and illustrations of that time, it is possible to picture those expeditions, the naturalists themselves and the assistants who accompanied them, as well as something of society in nineteenth century Brazil. Our research focuses on the iconography of these travelers. These images help us to understand the way these traveling naturalists viewed nature, the men living in the interior and the indigenous peoples. By comparing eight images selected to illustrate the travelers' campsites we sought to observe their similarities and differences, revealing what they tell us about these travelers, their expeditions and the context in which they worked.

RESUMEN

Conventional wisdom has had it that the naturalist Alfred Russel Wallace and his colleague Henry Walter Bates journeyed to the Amazon in 1848 with two intentions in mind: to collect natural history specimens, and to consider evidential materials that might reveal the causal basis of organic evolution. This understanding has been questioned recently by the historian John van Wyhe, who points out that with regard to the second matter, at least, there appears to be no evidence of a "smoking gun" variety proving it so. In the present essay the circumstances of Wallace's interest in the matter are reviewed, and van Wyhe is taken to task with alternate explanations for the facts he introduces in his argument. The conclusion is that Wallace almost certainly did have the second objective in mind when he left for both the Amazon, and the Far East.

RESUMEN

Barro Colorado Island (BCI), Panama, may be the most studied tropical forest in the world. A 1,560-hectare island created by the flooding of the Panama Canal, BCI became a nature reserve and biological research station in 1923. Contemporaries saw the island as an "ark" preserving a sample of primeval tropical nature for scientific study. BCI was not simply "set aside," however. The project of making it a place for science significantly reshaped the island through the twentieth century. This essay demonstrates that BCI was constructed specifically to allow long-term observation of tropical organisms--their complex behaviors, life histories, population dynamics, and changing species composition. An evolving system of monitoring and information technology transformed the island into a living scientific "archive," in which the landscape became both an object and a repository of scientific knowledge. As a research site, BCI enabled a long-term, place-based form of collective empiricism, focused on the study of the ecology of a single tropical island. This essay articulates tropical ecology as a "science of the archive" in order to examine the origins of practices of environmental surveillance that have become central to debates about global change and conservation.

RESUMEN

A formação e o estudo de coleções de história natural e de paleontologia participaram da instauração da ordem política do Império do Brasil, delineando também uma ordem científica. A simbiose entre ciência e nação encontrou em Peter W. Lund, iniciador dos estudos de paleontologia em nosso país, um agente ativo e constante. As coleções e escritos desse naturalista deram amparo à visualização do passado e à escrita da história em museus, instituições científicas e culturais brasileiras e europeias. As disputas pelo ordenamento político sob as Regências e a Maioridade foram acompanhadas de perto pelo estudo e a explicação das formas de vida e do globo no passado.

The formation and study of natural history and paleontology collections was part of the installation of political order under the Empire of Brazil, as well as the establishment of a scientific program. The symbiosis between science and the nation was actively promoted by Peter W. Lund, pioneer of paleontology studies in the country. The collections and writings produced by the naturalist lent support to the visualization of the past and the writing of history in Brazilian and European scientific and cultural institutions and museums. The disputes over the political order under the Regencies and the Majority were closely accompanied by the study and explanation of the forms of life and the planet found in the past.
