Museum specimens serve as more than relics; they are vital to understanding the biodiversity of the past and shaping conservation efforts for the future. Each specimen, carefully preserved, provides a glimpse into the genetic, environmental, and ecological aspects of different eras. Through the Discovery Lecture Series: Using museum specimens to look into the past and to inform the future, scientists explore the multitude of ways these collections aid research and conservation.
Globally, museum collections house millions of specimens collected over centuries. These specimens, encompassing a broad array of flora and fauna, offer unparalleled insights into historical biodiversity and evolutionary trends. By examining morphological characteristics, scientists can trace the evolutionary changes within species, offering an understanding of how various life forms have adapted—or failed to adapt—to environmental shifts. Such studies enrich our comprehension of the natural world, revealing patterns of extinction and survival that are crucial for predicting future biodiversity changes.
Museum specimens are crucial in informing future conservation efforts. As biodiversity faces unprecedented threats from climate change, deforestation, and human expansion, understanding past ecosystem changes becomes vital. Historical specimens serve as benchmarks, enabling scientists to identify shifts in species distributions, population dynamics, and genetic diversity over time. This information guides the development of effective conservation strategies, focusing on habitat preservation, restoration efforts, and biodiversity maintenance. With this data, conservationists can weigh historical baseline conditions against current states, allowing for data-driven initiatives to mitigate biodiversity loss.
Zoological specimens are indispensable for researching environmental changes and their impacts. Specimens collected from diverse habitats record the environmental conditions of their time. By studying certain species’ tolerance and adaptability, researchers can predict how current and future species might respond to ongoing ecological changes. Moreover, these specimens provide a historical record of pollutants, offering invaluable data to assess human impacts on ecosystems. This scientific foundation is critical to creating policies and initiatives targeting ecosystem health and integrity.
The integration of modern technology amplifies the research potential of historic collections. Advanced techniques such as DNA sequencing, X-ray imaging, and isotopic analysis breathe new life into older specimens. DNA analysis allows researchers to explore genetic variations and evolutionary relationships across time. X-ray imaging reveals anatomical features without damaging the specimen, while isotopic analysis can provide data on past diets and habitats. Collectively, these technologies offer a comprehensive understanding of species’ life histories, promoting informed conservation practices and facilitating cutting-edge research in evolutionary biology.
Collaboration among museums, zoos, and conservation bodies plays a significant role in biodiversity studies. Each institution brings unique strengths and perspectives, creating a synergistic approach to research and conservation efforts. Zoos provide living populations for behavioral and ecological studies, while museums offer extensive historical datasets through their collections. International collaborations foster information-sharing and resource-pooling, enhancing research capabilities and conservation successes. This united front is essential to tackling biodiversity challenges globally, promoting the sustainable management of natural resources and ensuring the survival of diverse species.
In summary, museum specimens are invaluable assets, bridging the past and future in biodiversity research and conservation. As we continue to navigate environmental challenges, the insights gleaned from historical collections guide our understanding and actions, fostering a sustainable relationship with the natural world. The Discovery Lecture Series encapsulates the unprecedented importance of these specimens in informing our ecological future, inspiring continued investigation and collaboration across sectors and disciplines.

Source Description
Natural history museums inspire wonder and awe amongst the public. Displays and dioramas detail the diversity of life on our planet, living in various habitats and on different continents. Fossil skeletons of dinosaurs and other extinct creatures highlight life that was once abundant, but is no longer with us as a result of our constantly changing planet. But in addition to the information that is showcased to the public, there is another side of museums, one that is rarely seen by most visitors, but is where the discoveries that are presented to the public are revealed. This talk will focus on the other side of natural history museums – the behind-the-scenes scientific collections and the science that is conducted using them. The importance of museum collections, why we have them and maintain them, and what they are used for will be discussed, specifically focusing on the fish collection at the Natural History Museum of Los Angeles County (NHMLA). Traditional uses of museum collections will be presented with stories of new species discoveries and efforts to untangle the fish Tree of Life. Surprising new uses of museum specimens will also be discussed with a fascinating example of using preserved fishes to understand the impacts that microplastics have had on our local southern California marine ecosystems over the past 80 years. This project involves several different fish species that are locally abundant and that serve different ecological roles in their communities, ranging from toothy deep-sea predators, to blue-eyed friendly herbivores. The talk will conclude with a discussion on how museums and the specimens they house can help inform public policy and lead us to a more sustainable relationship with the natural world around us.
Dr. William (Bill) Ludt is the Associate Curator of Fishes at the Natural History Museum of Los Angeles County, a position he has held since 2019. He holds a B.S. from the University of Arizona, a M.S. from the University of Texas at Austin where he worked primarily at the UT Marine Science Institute, and a Ph.D. from Louisiana State University. Prior to starting at the NHMLA he was the first Collette Postdoctoral Fellow in Systematic Ichthyology at the Smithsonian National Museum of Natural History. His research aims to determine the factors that have influenced the biodiversity of fishes that we see on our planet and determine how patterns of fish biodiversity have changed over time. He also is interested in conserving and protecting marine biodiversity by understanding the impact that we have on our marine environments. To better understand fish biodiversity and answer the questions he is interested in, he leverages the variety of data that can be obtained from museum specimens, and also actively travels to conduct field work and add specimens to museum collections worldwide.
