Baleias, peixes-boi e tartarugas (de água doce e marinhas) estão entre as espécies aquáticas mais valorizadas pelos colonos e exploradores europeus do Atlântico ao longo do período moderno. No processo de contato com a ecologia tropical, com base numa perceção de abundância e de recursos inesgotáveis, estes animais foram selecionados como recursos de subsistência, mas também mercantilizados pelos europeus. Isso aconteceu, muitas vezes, com base na observação da sua utilização e captura pelas sociedades locais para fins de alimentação, transformação em utensílios, ou como elementos integrantes das suas práticas religiosas e culturais. Neste trabalho, iremos abordar algumas das questões da exploração local de recursos aquáticos, construídas sobre perceções locais e indígenas e transformadas pelas estruturas coloniais da época moderna. É discutido o caso de manatins e de tartarugas para a América Central e do Sul a partir das fontes históricas, principalmente, para os impérios ibéricos. Assim, mostramos como os animais aquáticos têm sido sistematicamente apropriados, explorados, transformados e mercantilizados, deixando adivinhar algumas das implicações sociais, políticas, econômicas e ambientais para o Atlântico moderno. Estas interações e relações pré-industriais de longa distância, que designamos como teleconexões oceânicas, são sustentadas na utilização e extrações de animais e impactos em ecossistemas do mar aberto, zonas costeiras e estuarinas.

Sirenia, an iconic marine taxon with a tropical and subtropical worldwide distribution, face an uncertain future. All species are designated ‘Vulnerable’ to extinction by the IUCN. Nonetheless, a comprehensive understanding of geographic structuring across the global range is lacking, impeding our ability to highlight particularly vulnerable populations for conservation priority. Here, we use ancient DNA to investigate dugong (Dugong dugon) population structure, analysing 56 mitogenomes from specimens comprising the known historical range. Our results reveal geographically structured and distinct monophyletic clades characterized by contrasting evolutionary histories. We observe deep-rooted and divergent lineages in the East (Indo-Pacific) and obtain new evidence for the relatively recent dispersal of dugongs into the western Indian Ocean. All populations are significantly differentiated from each other with western populations having approximately 10-fold lower levels of genetic variation than eastern Indo-Pacific populations. Additionally, we find a significant temporal loss of genetic diversity in western Indian Ocean dugongs since the mid-twentieth century, as well as a decline in population size beginning approximately 1000 years ago. Our results add to the growing body of evidence that dugong populations are becoming ever more susceptible to ongoing human action and global climate change.

Diachronically, Mesopotamian data pertaining to the religious spheres point to a transversal notion that deities were considered responsible for every cause–effect event observed/experienced by humans in their natural/cosmic surroundings. Such notion is especially visible on texts pertaining to the restoration of human health, where such an aspect was ultimately considered as a divine prerogative. Yet, these textual data also show how natural elements were basilar to the success of healing practices when thoroughly manipulated by specialists. Their examination through a perspective that intertwines the apparatus of History of Religions and Environmental History thus reveals great potential for contributing to the topic of human/nonhuman entanglements in the longue durée. With this paper, we propose to revisit the uses of aquatic fauna as displayed in Babylonian and Assyrian healing texts dated to the second half of the 2nd millennium and the first half of the 1st millennium BC. Although at a preliminary stage, our research has been guided by the combined theoretical-methodological perspective above-mentioned, aiming at highlighting the great importance conferred to these animals. Ultimately, we aim at stressing the importance of addressing the dependence of Mesopotamian specialists and patients on such elements of Nature to better understand this ancient context.

We contend that the harvest of marine resources played a critical, but as yet underappreciated and poorly understood, role in global history. In a review of the field of marine environmental history and archaeology we conclude that while much progress has been made, especially in the last two decades, fundamental questions remain unanswered. In order to make full use of the rapid growth of Big Data and ongoing methodological breakthroughs there is a need for collaborative and comparative research. Such joint efforts on a global scale must be guided by a focus on common, simple yet challenging, questions. We propose a Human Oceans Past research agenda to call for multi- and trans-disciplinary archaeological, historical and palaeoenvironmental/palaeoecological research to investigate: (1) when and where marine exploitation was of significance to human society; (2) how selected major socio-economic, cultural, and environmental forces variously constrained and enabled marine exploitation; and (3) what were the consequences of marine resource exploitation for societal development. We contend that this agenda will lead to a fundamental revision in our understanding of the historical role of marine resources in the development of human societies.

Como podemos contar uma história humana num mundo mais-do-que-humano? Como se percebem as influências e consequências para pessoas e sociedades do mundo natural e físico que as envolve e do qual dependem para sobreviver, sem esquecer os vários agenciamentos envolvidos e interligados? E como o fazemos no mundo líquido, fluído, azul e profundo dos oceanos e águas costeiras do planeta? A problemática é histórica, mas reflete-se também na atualidade e futuro das sociedades humanas e sua relação e dependência dos ecossistemas e recursos dos mares e oceanos. Nesta nota científica abordo o valor das humanidades para o conhecimento histórico dos oceanos e o seu contributo para aumentar a literacia para os oceanos. Uso o caso de estudo da história natural e exploração de manatins com vista a perceber áreas de distribuição no passado e apresento o projeto interdisciplinar e colaborativo ‘4-Oceans’ e sua agenda de investigação. Para tal, revejo brevemente a história ambiental de manatins e pessoas no Atlântico da época moderna e refiro-me à importância de considerar os seres humanos como agentes ecológicos e outras espécies animais como co-construtores das narrativas históricas.

Listening to a story stimulates children to understand concepts and vocabulary, while developing their background knowledge. Previous research indicates that the use of scientifically accurate literature helps children connect to the natural world. Promoting environmental education (EE) should be of utmost importance in school curricula, providing opportunities to students to improve their knowledge regarding the environment, and how to protect it. Particularly, marine ecosystems have been subject to increasing pressures, highlighting the importance of taking Ocean Literacy (OL) to the classroom. Drawing attention to more relatable environments, like a river, by tailoring OL activities to local contexts and community interests, might be an efficient strategy to raise awareness of ocean problems. A children’s book, written by a MARE (Marine and Environmental Sciences Centre, Portugal) researcher, with a macrobenthic invertebrate as the main character, was the springboard for an outreach project, developed with elementary school students. The project aimed to assess the impact of using a children’s book as a tool to promote environmental awareness, focusing on river basin ecological issues. Researchers conducted reading sessions of the book with 89 female and 87 male elementary school students (ages between 8–10). The target audience were students from two public and two private schools from an urban city and a city with a strong fishing tradition, aiming to assess if the reading session impacted students differently according to their background. A sequential explanatory mixed methodology was applied, using a pretest-posttest design, combined with focus group interviews in the last phase, to measure change in students’ knowledge, before and after the reading. Results demonstrated that there was an overall improvement in students’ knowledge regarding river basin biodiversity and anthropogenic threats they are subjected to. Furthermore, the idea that local impacts on rivers will also reach and influence the ocean was always present throughout the reading sessions. Students’ background, such as the type of school and region influenced higher posttest score results. In particular, students from Lisbon had higher scores in posttest results, while the same was observed for students from private schools. The present research revealed that a children’s book is an effective tool to improve environmental knowledge, while being an entertaining activity for students.

This article addresses broad and plural concepts of landscape, considering its diversity of meanings and uses, which go far beyond its environmental and geographical connotations. It discusses the relationship between humanity and the rest of the natural world as a global process that combines physical and cultural aspects, and it seeks to highlight the contribution of environmental humanities to the understanding of these. Given the multiple conceptual interpretations and meanings of landscapes, we argue that current research trends are good examples of what we can consider as postdisciplinary approaches, challenging both disciplinary and interdisciplinary models of analysis. In this context, we use the recent pandemic scenarios as an example.

Cultural constructions of landscapes, space and environments, and of people’s relationship with nature, have in the Cape Verde Islands a perspective of their own and might have been mediated by the whale. To address perceptions about these marine mammals, historical sources, literature, art, memory and heritage were considered. Whaling influenced history and diaspora and is reflected in literary productions. Remains of whales are found in museums and used as decorative pieces and local art. We found the Cape Verdean seascapes as being culturally and naturally constructed and the whale occupies a true ‘place’ of convergence.

Marine megafauna has always elicited contrasting feelings. In the past, large marine animals were often depicted as fantastic mythological creatures and dangerous monsters, while also arousing human curiosity. Marine megafauna has been a valuable resource to exploit, leading to the collapse of populations and local extinctions. In addition, some species have been perceived as competitors of fishers for marine resources and were often actively culled. Since the 1970s, there has been a change in the perception and use of megafauna. The growth of marine tourism, increasingly oriented towards the observation of wildlife, has driven a shift from extractive to non-extractive use, supporting the conservation of at least some species of marine megafauna. In this paper, we review and compare the changes in the perception and use of three megafaunal groups, cetaceans, elasmobranchs and groupers, with a special focus on European cultures. We highlight the main drivers and the timing of these changes, compare different taxonomic groups and species, and highlight the implications for management and conservation. One of the main drivers of the shift in perception, shared by all the three groups of megafauna, has been a general increase in curiosity towards wildlife, stimulated inter alia by documentaries (from the early 1970s onwards), and also promoted by easy access to scuba diving. At the same time, environmental campaigns have been developed to raise public awareness regarding marine wildlife, especially cetaceans, a process greatly facilitated by the rise of Internet and the World Wide Web. Currently, all the three groups (cetaceans, elasmobranchs and groupers) may represent valuable resources for ecotourism. Strikingly, the economic value of live specimens may exceed their value for human consumption. A further change in perception involving all the three groups is related to a growing understanding and appreciation of their key ecological role. The shift from extractive to non-extractive use has the potential for promoting species conservation and local economic growth. However, the change in use may not benefit the original stakeholders (e.g. fishers or whalers) and there may therefore be a case for providing compensation for disadvantaged stakeholders. Moreover, it is increasingly clear that even non-extractive use may have a negative impact on marine megafauna, therefore regulations are needed.

Objective: Some studies have hypothesized that an unfavourable higher order aberrometric profile could act as an amblyogenic mechanism and may be responsible for some amblyopic cases that are refractory to conventional treatment or cases of “idiopathic” amblyopia. This study compared the aberrometric profile in amblyopic children to that of children with normal visual development and compared the aberrometric profile in corrected amblyopic eyes and refractory amblyopic eyes with that of healthy eyes. Methods: Cross-sectional study with three groups of children – the CA group (22 eyes of 11 children with unilateral corrected amblyopia), the RA group (24 eyes of 13 children with unilateral refractory amblyopia) and the C group (28 eyes of 14 children with normal visual development). Higher order aberrations were evaluated using an OPD-Scan III (NIDEK). Comparisons of the aberrometric profile were made between these groups as well as between the amblyopic and healthy eyes within the CA and RA groups. Results: Higher order aberrations with greater impact in visual quality were not significantly higher in the CA and RA groups when compared with the C group. Moreover, there were no statistically significant differences in the higher order aberrometric profile between the amblyopic and healthy eyes within the CA and RA groups. Conclusions: Contrary to lower order aberrations (e.g., myopia, hyperopia, primary astigmatism), higher order aberrations do not seem to be involved in the etiopathogenesis of amblyopia. Therefore, these are likely not the cause of most cases of refractory amblyopia.

News about exotic large marine animals started to spread around Europe since the second half of the 16th century. These, containing both written and visual information, were typically included in encyclopedias and treaties, but also in pamphlets that easily moved from one person to another, disseminating the available information through distinct nets of knowledge and to different audiences. By the 18th century, both as part of newspapers and pamphlets, information about strange natural events were amply printed and translated in several vernacular languages. These became increasingly of great interest to common people and not only to scholars, naturalists or collectors, but also practitioners and craftsmen. Printed news included records and rare occurrences of local and exotic fauna. The analysis of Portuguese sources contributed with good examples of such events, firstly published in Portugal and then copied and translated to other vernacular tongues. It is the case of a fin whale stranded in the Tagus estuary (Lisbon) reported in the Gazeta de Lisboa 1723 with a detailed description of the specimen, accompanied by an illustration of the whale with its measures, which was afterwards translated and printed in a German pamphlet. Here, the transfer of natural history accounts and communication of new concepts of the natural world was conducted from the periphery to the centre of Europe. Other news of large marine animals stranding on the Portuguese shore and respective illustrations were also produced. All together they seem to show the interest of all levels of the society for such rare and strange events. Moreover, these whales in pamphlets and in other publications contribute to the construction of a modern European concept of the natural world.

Patrick O’Brian inspired this work, with his 1934 book of chronicles “Beasts Royal,” where he gives a voice to animals. Therein, among other animals, we find Skogula, a young sperm whale journeying with his family group across the South Seas and his views on the surrounding world, both underwater and on land. This paper tells a story of historical natural events, from the viewpoint of a fin whale that travelled, rested and stranded in the Tagus estuary mouth (Lisbon, Portugal) during the early 16th century. It allows us to move across time and explore the past of this estuarine ecosystem. What kind of changes took place and how can literature and heritage contribute to understand peoples’ constructions of past environments, local maritime histories and memories? In the second part of this essay we present a fictional short story, supported on historical documental sources and imagery research where Lily, the whale, is the main character. Thus, we see the Tagus estuary as perceived through this whale’s-eye view. Finally, we discuss past earthquakes, whale strandings, the occurrence of seals and dolphins and peoples’ perceptions of the Tagus coastal environment across time. We expect to make a contribution to the field of the marine environmental humanities. We will do so both by addressing, by means of this literary approach, the writing of “new thalassographies,” oceanic historiographies and “historicities” and by including all intervening actors—people, animals and the physical space—in the understanding of the past of more-than-human aquatic worlds.

The former occurrence of the North Atlantic right whale Eubalaena glacialis on the Portuguese coast may be inferred from the historical range of that species in Europe and in NW Africa. It is generally accepted that it was the main prey of coastal whaling in the Middle Ages and in the pre-modern period, but this assumption still needs firming up based on biological and archaeological evidence. We describe the skeletal remains of right whales excavated at Peniche in 2001-2002, in association with archaeological artefacts. The whale bones were covered by sandy sediments on the old seashore and they have been tentatively dated around the 16th to 17th centuries. This study contributes material evidence to the former occurrence of E. glacialis in Portugal (West Iberia). Some whale bones show unequivocal man-made scars. These are associated to wounds from instruments with a sharp-cutting blade. This evidence for past human interaction may suggest that whaling for that species was active at Peniche around the early 17th century.

The history between cetaceans and humans is documented throughout time not only in reports, descriptions, and tales but also in legal documents, laws and regulations, and tithes. This wealth of information comes from the easy spotting and identification of individuals due to their large size, surface breathing, and conspicuous above water behaviour. This work is based on historical sources and accounts accounting for cetacean presence for the period between the 12th and 17th centuries, as well as scientific articles, newspapers, illustrations, maps, non-published scientific reports, and other grey literature from the 18th century onwards. Information on whale use in Portugal's mainland has been found since as early as the 12th century and has continued to be created throughout time. No certainty can be given for medieval and earlier events, but both scavenging of stranded whales or use of captured ones may have happened. There is an increasing number of accounts of sighted, stranded, used, or captured cetaceans throughout centuries which is clearly associated with a growing effort towards the study of these animals. Scientific Latin species denominations only started to be registered from the 18th century onwards, as a consequence of the evolution of natural sciences in Portugal and increasing interest from zoologists. After the 19th century, a larger number of observations were recorded, and from the 20th century to the present day, regular scientific records have been collected. Research on the environmental history of cetaceans in Portugal shows a several-centuries-old exploitation of whales and dolphins, as resources mainly for human consumption, followed in later centuries by descriptions of natural history documenting strandings and at sea encounters. Most cetaceans species currently thought to be present in Portuguese mainland waters were at some point historically recorded.

RESUMO Com uma distribuição geográfica histórica alargada em zonas costeiras, ambientes de transição e fluviais do Oceano Atlântico tropical, o manatim (manati das Índias Ocidentais, peixe-boi ou iguaragua do Brasil colonial) era bastante valorizado. As fontes documentais e iconográficas dos séculos XVI e XVII mostram-nos que era usado como alimento, para fins medicinais, para produzir utensílios ou como animal de estimação, mas seu valor económico e simbólico foi igualmente dominante. A sobre-exploração contínua conduziu ao desaparecimento de muitas populações de manatins, os quais hoje enfrentam o risco de extinção. Pretendemos explorar do ponto de vista da história ambiental marinha o significado pragmático e simbólico dos manatins numa ligação próxima aos valores atribuídos aos rios e cursos de água. Esperamos também contribuir para colocar manatins e o seu ecossistema no centro de uma discussão sobre contextos e interações ambientais e socioculturais das sociedades indígenas e coloniais nas Américas do período moderno.
