Ichthyological surveys have traditionally been conducted using whole specimen capture-based sampling with varied, but conventional fishing gear. Recently, environmental DNA (eDNA) metabarcoding has emerged as a complementary, and possible alternative, approach to whole specimen approaches. In the tropics, where much of the diversity remains undescribed, vast reaches remain unexplored, and anthropogenic activities are constant threats; there have been few eDNA attempts for ichthyological inventories. We tested the discriminatory power of eDNA using the 12S rRNA MiFish primers with existing public reference libraries and compared this with capture-based methods in two distinct ecosystems in the megadiverse Amazon basin. eDNA provided an accurate snapshot of the fishes at higher taxonomic levels and corroborated the effectiveness of eDNA to detect specialized fish assemblages. Some flaws in fish metabarcoding studies are routine issues addressed in natural history museums. Thus, by expanding their archives to include eDNA and adopting a series of initiatives linking collection-based research, training and outreach, natural history museums can enable the effective use of eDNA to survey Earth′s hotspots of biodiversity before taxa go extinct. Our project surveying poorly explored rivers and using DNA vouchered archives to build metabarcoding libraries for Neotropical fishes can serve as a model of this protocol.

Natural history museums are unique spaces for interdisciplinary research and educational innovation. Through extensive exhibits and public programming and by hosting rich communities of amateurs, students, and researchers at all stages of their careers, they can provide a place-based window to focus on integration of science and discovery, as well as a locus for community engagement. At the same time, like a synthesis radio telescope, when joined together through emerging digital resources, the global community of museums (the ‘Global Museum’) is more than the sum of its parts, allowing insights and answers to diverse biological, environmental, and societal questions at the global scale, across eons of time, and spanning vast diversity across the Tree of Life. We argue that, whereas natural history collections and museums began with a focus on describing the diversity and peculiarities of species on Earth, they are now increasingly leveraged in new ways that significantly expand their impact and relevance. These new directions include the possibility to ask new, often interdisciplinary questions in basic and applied science, such as in biomimetic design, and by contributing to solutions to climate change, global health and food security challenges. As institutions, they have long been incubators for cutting-edge research in biology while simultaneously providing core infrastructure for research on present and future societal needs. Here we explore how the intersection between pressing issues in environmental and human health and rapid technological innovation have reinforced the relevance of museum collections. We do this by providing examples as food for thought for both the broader academic community and museum scientists on the evolving role of museums. We also identify challenges to the realization of the full potential of natural history collections and the Global Museum to science and society and discuss the critical need to grow these collections. We then focus on mapping and modelling of museum data (including place-based approaches and discovery), and explore the main projects, platforms and databases enabling this growth. Finally, we aim to improve relevant protocols for the long-term storage of specimens and tissues, ensuring proper connection with tomorrow’s technologies and hence further increasing the relevance of natural history museums.

Society in general is distant from scientific culture, it is required to bring scientific knowledge closer to the population. In this context, an effective and attractive way for scientific dissemination is the establishment of natural history museums, which are institutions of knowledge, displaying the past. Natural history museums have the natural world as their object of study; and their collections may contain the most diverse types of materials (local and/or from various parts of the world), such as zoological, botanical, geological, archaeological, among others. Scientific collections are the largest and most important source of authoritative biodiversity data, contributing to studies of biodiversity composition, evolutionary (morphological and genetic), biogeographical, phenological, as well as geological. The materials present in these collections may serve for temporal comparison, being useful to produce predictive models. Likewise, they have a fundamental role in safeguarding type specimens, i.e. the first organisms identified to describe and name a new species. In addition, there is the component available to visitors in general, in order to raise public awareness on the preservation of the local fauna and flora and of other places in the world. In this way, the museums serve both the academic-scientific public and visitors who come to these sites for recreational purposes. It is intended to promote, in Vila Nova de Cerveira, the Natural History Museum of the Iberian Peninsula - NatMIP (“Museu de História Natural da Península Ibérica”), which intends to collect materials for scientific purposes, mainly Iberian.

Abstract This paper will explore the significance of the expeditions under- taken by Wanda Hanke (1893-1958) in South America, of the networks she established in the region, as well as of her contributions to ethnological studies, in particular her compilation of extensive data and collections. Through Hanke's experience, it is possible to elucidate aspects of the history of ethnology and that of the history of museums in Brazil, as well as to emphasize the status of female participation in these areas. Wanda Hanke spent 25 years of her life studying the indigenous groups of Argentina, Bolivia, Brazil and Paraguay and collecting ethnological objects for natural history museums. Trained in medicine and philosophy, she began to dedicate herself to ethnological studies in her forties, and she travelled alone, an uncommon characteristic among female scientists in the 1940s, in Brazil.
