Internship Projects with the Thompson Collection

Volunteers and students enrolled in the BIO195/196 internship course have a variety of projects to choose from to address the preservation, organization, and educational reach of the near-300,000 specimens housed in the Thompson Zoological Collections. In the first semester it was offered, interns working alone or in teams took up ongoing projects of inventorying and digitizing the collections, as well as established new insect and vertebrate teaching collections to assist much needed hands-on learning in the biology department. Read about their goals and progress below.

Vertebrate Teaching Collection Spring 2023

As part of the vertebrate teaching collection team, we work with a variety of vertebrate specimens from all different Orders including Carnivora, Rodentia, Artiodactyla, Lagomorpha and more. Our aim is to identify and catalog new specimens, organize the existing collection, and articulate complete skeletons. Cataloging involves assigning each specimen a unique number and recording its taxonomic information, then inputting that data into our virtual database. Articulation includes processing bones to remove any remaining flesh and grease before using materials such as glue, wire, and wooden supports to pose the skeletons. These specimens are not only useful teaching tools but also are valuable for research purposes, allowing scientists from all over the world to access our digitized samples.

Sydney Madera - Sophomore Animal Science Major. I joined the Natural History Collections because I thought it would be a unique way to get some hands-on experience with different animal specimens. Next year, I plan on starting research about how climate change may be causing animals to shrink in size and will be using Natural History Collection data to do this research. 

Colby Carach - Senior Biology Major. I was interested in joining the Natural History collections because it provides a great opportunity to get real world experience working with skeletal specimens, be part of a collaborative team, and be granted some freedom when it comes to your project. 

Rachel Ford - Sophomore Animal Science Major. I joined the Natural History Collections to gain experience with museum preservation and to learn about research done with historical specimens. Next year I will start my Honors thesis researching ectoparasites gathered from local vertebrates using recent collection data and older specimens from the museum.

As part of the vertebrate teaching collection team, we work with a variety of vertebrate specimens from all different Orders including Carnivora, Rodentia, Artiodactyla, Lagomorpha and more. The collection includes everything from furs/skins to skulls to entire skeletons and are largely donated from private collectors. Our aim is to identify and catalog new specimens, organize the existing collection, and articulate complete skeletons. Cataloging involves assigning each specimen a unique number and recording its taxonomic information, then inputting that data into our virtual database. We have recently started a museum catalog document that includes every specimen and that is ordered by their Class down to their Species. This document will be used as a guide in organizing the layout of the specimens in order to facilitate simple and easy location of any individual within the collection. The specimens within the collection must also be maintained and repaired as damage happens and many teeth become loose over time. Another one of our tasks is articulation which includes processing bones to remove any remaining flesh and grease as well as whitening them before using materials such as glue, wire, and wooden supports to pose the skeletons. The specimens in this collection are mainly used for teaching purposes in classes offered at UVM but can also be used by other scientists around the world with the implementation of digitized samples. They allow students to learn about the anatomical features that differentiate Classes and Orders as well as grant researchers with a plethora of data that is accessible remotely.

Pember Egg Collection Spring 2023

Vermont State Ornithologist (1923-1928) Karl Pember collected bird egg shells from as early as the late 1800s until his death in 1928. His collection was donated to the University of Vermont, containing over three thousand eggs which represent over 250 different species and 57 families. Currently, the collection is in the process of being digitally cataloged and entirely rehoused in new containers. The collection includes eggs from several endangered species, and the age of many of the specimens makes them vital for understanding the effects of recent environmental changes, such as the introduction and widespread use of the pesticide DDT, on avian species.

Megan Schestag (‘26) is a Wildlife and Fisheries Biology major, originally from Grand Rapids, Michigan. Their hobbies include birding, listening to lots of music, and playing with their pet gerbils.

The Pember Egg Collection contains over 3,000 hollowed and preserved egg shells acquired by Karl Pember (Vermont State Ornithologist 1923-1928), along with his friends and colleagues, from the late 1800s into the beginning of the 20th century. The species represented by the collection include most (if not all) birds native to the state of Vermont, along with many others found in the United States and abroad. The eggs of several threatened or endangered species also feature in the collection, making it an essential and unique resource for the study of avian species.

Due to the many times this collection changed hands before reaching UVM and the rapid relocation of the Natural History Collections’ materials from Torrey Hall during the fire in 2017, almost all of the eggs were shuffled around to some degree. The drawers containing eggs and nests ranged in states of disarray from mostly organized to complete mess. Currently, student interns and museum staff are working to catalog, organize, and rehouse the entire Pember Egg Collection so that it may remain as intact as possible and be accessed by the greater scientific community for years to come.

Hymenoptera Organization Spring 2023

We have been phylogenetically organizing the Hymenoptera in the Insect Collection, and updating the online inventory with species classifications and specimen counts. This makes the collection more navigable, and accessible for researchers and students. We have also been working on identifying the unclassified Hymenoptera, and adding them to the collection. Having an organized collection and historic record of these insects can give researchers a glimpse into how changes in the environment affect these incredibly important organisms, and how their populations change over time. This, in turn, informs future research and broadens our understanding of the natural world!

Will Sheldon, Forestry, Freshman: I chose to intern at the collections because it is a great space to learn basic entomological skills and collections knowledge, and the collection is very impressive. My hobbies include herping, birding, and climbing.

Erin O’Mara, Environmental Science, Senior: I interned this semester because I wanted to learn more about museum collections, and what that research in this space looks like. I love being outside and exploring my surroundings, and so to see all these species I identify in the outdoors in a museum setting has been really interesting.

We have been phylogenetically organizing the Hymenoptera in the Insect Collection, and updating the online inventory with species classifications and specimen counts. This makes the collection more navigable, and accessible for researchers and students. The collection has specimens from all over, but of course, the majority of the inventory is Hymenopterans from Vermont. Many Hymenopterans are pollinators and parasites that play vital roles in ecosystems, but many families remain severely under-researched. We hope the collection aids in the research of the lesser-known families as well as the recognized ones.

At this point, all of the labeled specimens have been organized (although there may be incorrect labels). Now, we are working on identifying the unclassified Hymenoptera and adding them to the collection. In the future, as more specimens are added to the collection, we hope that the updated inventory and new method of organization will aid in a smooth integration process.

Digital Guard Hair Catalogue Spring 2023

The mammal hair catalogue is a collection of hairs from species ranging from muskrats (Ondatra zibethicus) shrews (genus Sorex). The hairs were collected from the scruffs of small mammals specimens from the Zadock Thompson Zoological Collection, placed on slides, barcoded and catalogued, before finally being photographed and uploaded to a digital catalogue. With the catalogue, we aim to assist in mammal hair identification by creating a collection of sample hairs complete with diagnostic traits. Hairs are relatively durable, sometimes remaining one of the only signs in the stomach or scat showing what an animal has eaten. This makes them an important tool for predator-prey studies and hair trapping.

Pia Carman is a first-year Animal Science major with a passion for animal and environmental health and conservation. Working with animals in UVM’s Natural History Collections has been an incredible opportunity for working on research with Vermont’s local mammals.

Alexis Mancha is a fourth-year Biology major with interests in studying mammals in Madagascar. Learning about the broad range of research that is capable with a natural history collection has peaked her curiosity about opportunities linked with collections.

The small mammal specimens used were accessed from UVM’s Zadock Thompson Zoological Collection, a catalogue of animals collected by a range of UVM researchers, faculty, and public donations. All mammals studied for the digital mammal hair catalogue are either from Vermont or from former lab colonies, including deer mice, voles, shrews, rats, and muskrats. A few particularly interesting specimens included two common shrews (Sorex cinereus), who were especially tiny at about nine centimeters long including their tails, and one smoky shrew (Sorex fumeus) who was even smaller.

All hairs collected were guard hairs, the durable hairs from the scruffs of mammals. These hairs were mounted on slides to be seen under a microscope, with which we took images of the internal structure called the medulla. We want to analyze these hairs for future research on predator-prey interactions. We eventually want to make a dichotomous key to help identify what hair the species belongs to.

Invertebrate Donations Spring 2023

My project has been bringing donated specimens into our museum’s database by logging them in an Excel spreadsheet and giving them QR code labels so they can easily be searched up. I’m not working with any particular taxon, but since I’m in the invertebrate wing I’ve been doing arthropods, mostly insects but a few arachnids and myriapods get in there too. After I’m done with the specimens I’m working with, they will be further integrated into the collection and put in drawers; this will make them easier to find when experts borrow them to identify them. Each specimen is an important data point that tells us that a species was present at a certain date in a certain location, which can help us understand how species’ ranges are changing in a changing world.

My name is Corey Seeley, and I am a student with junior standing majoring in Zoology. This is my first semester working in the Natural History Collections at UVM, and this internship was recommended to me by a professor last semester because she noticed my commitment to the study of life on earth and thought it would be a good fit.

In my project processing donated specimens, I was working in the invertebrate wing of the collection. The specimens I logged were all terrestrial arthropods, the vast majority being insects. A lot of the specimens had been donated by Ross Bell or Michael Sabourin, but they were not the only collector whose specimens I logged and barcoded. Most specimens were collected in Vermont, but there were some that were collected in other states or in Canada. Out of the many specimens I processed, a few stand out; I saw multiple specimens of an insect I had seen in my apartment, identified as boxelder bugs, as well as a really cool specimen of a grasshopper with its wings spread.

The invertebrate wing has a considerable backlog of boxes full of donated specimens, so I’d grab a box and then process each individual specimen. For each specimen, I would log any information on its pin in a spreadsheet; usually it was just collection information, but some specimens had identification information as well. Then I would have barcodes printed and give a barcode to each specimen and indicate in the spreadsheet the number on the specimen’s barcode label. Processing these donations is important because every individual data point of where and when a species was collected helps paint a bigger picture of the species’ range and habitat, and how it might have changed over time. The data from donated specimens also paints a more complete picture of the biodiversity of a given location.

Lepidoptera Organization Spring 2023

We are currently inventorying, cataloging, and labeling all the Lepidoptera specimens in the collection. The specimens that from Vermont have all their label information entered onto a digital master list and given an additional label with a QR code. The labeling and cataloging are for the 2023 Vermont Butterfly Atlas, which is looking at distribution and densities of Lepidoptera populations in Vermont. The historical data from the Natural History Museum’s Lepidoptera collection as well as the surveying conducted by the Vermont Butterfly Atlas can help to identify species that might need conservation status and climate impacts on range and density.

Our group is working with the Lepidoptera collection. Our task was to inventory and label all of the Leipoptera specimens from Vermont in our collection, so we could document those specimens in the Vermont Butterfly Atlas. We have been working on the cabinets and drawers with Lepioptera to catalog their genus, family, and species name along with the collector, identifier, and the location of the specimens. All of the Lepidoptera specimens come from a range of collectors and countries. There are some beautiful butterflies and moths from Peru and Fiji. There are some individuals who contributed hundreds of specimens and others came from students here.

Juliet Hoven: I am a senior zoology major with a minor in ecological sciences! I'm interested in animal behavior related to climate change and want to work with marine arthropods or reptiles. I started working in the collections because I enjoyed taking behavioral ecology with Dr. Sara Cahan and wanted to continue working with her. Now I just enjoy working with and learning the importance of the bug specimens we have at the museum.

Fischer Morrissey: I am a junior agroecology major. I’m interested in pest ecology particularly with moths and Lepidoptera in agriculture. With climate change I am also interested in conservation of insects and range shifts. I started working in the collection in hopes to become more familiar with Lepidoptera taxonomy and phylogeny!

Maeve Tomas: I am a senior biology major with a minor in psychological science. I am most interested in ecology and conservation of biodiversity in both plant and animal systems and how plants and animals interact with each other to form these relationships. I hope to work with a conservation organization aimed at combatting ecological problems brought on by climate change. I started working in the collections after realizing how important these resources are for research and environmental history data and wanted to learn first hand how to work with the collections.

Parasite Digitization Spring 2023

This project focuses on imaging of ectoparasites collected from small mammals in order to better aid future research and identification of parasites. Ectoparasites are often very difficult to accurately identify, so this project will clearly photograph a large sample of fleas and ticks for use by other researchers. By adding to parasite image databases, researchers can use our images as keys for identification of their collected parasites for simple and accurate analyses.

The parasite imaging is being completed by Matt Heilbronn. Matt is a senior microbiology major in the College of Agriculture and Life Sciences at UVM with minors in wildlife biology and zoology. Matt is also a senior undergraduate researcher in the UVM Wildlife Pathogens Lab, where he studies the spillover of avian malaria parasites into invasive bird species.

Ectoparasites were collected off small mammals sourced from graduate student research and ecological monitoring projects such as the Colby Hill Ecological Project.  The vast majority of the ectoparasites are fleas, where sampled mammals ranged from one or two fleas to over a dozen on a single host! This project has been exciting as I had been able to advance my skills under the microscope and gain experience in identifying key structural components in ectoparasite identification.

Small Mammal Specimen Preparation Spring 2023

The project I am working on is various types of specimen preparation. I work with small mammals; this includes members of the orders Rodentia and Eulipotyphla, specifically the Talpidae and Soricidae families. I started with the preparation of skulls, and later moved on to occasional tissue and skin preparation along with the skulls. Most of my work goes into the UVM natural history collection for future reference, but tissue samples are being used currently for pathogen research.

My name is Reece Mashia; I'm a senior zoology BS major. Being hands on with animals and contributing to a collection that assists many in their research was a good way to wrap up my college career.

The project I was working on was various types of specimen preparation. Most of these small mammal specimens were donated by ecological monitoring programs such as the Vermont Herp Atlas and the Colby Hill Ecological Project. I started with the preparation of skulls, and later moved on to occasional tissue and skin preparation along with the skulls. The Specimens can be used in different types of biological research such as tissue samples contributing to pathogen research, and the skins and skulls grow the natural history collection here at UVM.

Most of the work was a bit grisly at first as working with fully intact specimens was unfamiliar. Skull preparation was the simplest as it was the job with the least scissor work and required little understanding of the anatomy of the specimen. Tissue collection was the most involved with the animals’ anatomy but as soon as it was done a few times; every specimen’s heart and liver were in the same place so getting to them was not terribly hard. Skin preparation was very difficult as it was a gentle process that required a lot of getting used to, although I found this the most enjoyable, albeit I was a bit rough in this domain.

Arthropod Collection Digitization Fall 2022

The Zadock Thompson Zoological Insect Collection has hundreds of thousands of specimens that need to be brought into the 21st century. Digitizing the ZTZIC consists of photographing the specimen; translating data attached to the collection (species, collection location, etc) into a digital version; and linking the collection to a barcode in order to make it easy to find in the Symbiota Collections of Arthropods Network. Digitizing a collection creates a redundancy in the event of disaster and makes scientific collaboration and global use of collections easier. From September to December 2022, just over 200 specimens have been uploaded to the database.

This project was carried out by Brady Miller and Rho Kackley. Brady is a sophomore majoring in Biology with a minor in Wildlife Biology from Charlotte, NC. In her free time she enjoys crocheting, cooking, and playing with animals. Rho is a junior studying Plant Biology, with an emphasis on non-vascular plants, from Chicago, IL. They spend their free time practicing martial arts and playing tabletop games with their friends. Digitizing an entire collection is no easy task. The Zadock Thompson Zoological Insect Collection has hundreds of thousands of species from around the globe in need of digitizing and this project only began to chip away at the workload. In order to photograph the specimens, a lightbox was used with lights on the top and sides. The specimen was placed in the lightbox on a pedestal with the barcode in front. Dinocapture was used to read and attach the barcode to the specimen as an image was taken. Data attached to the specimens’ pins, such as where and when they were collected and by whom, were entered into a spreadsheet and associated with the specimen’s barcode. This was uploaded to Symbiota Collections of Arthropods Network (SCAN) with the corresponding collections data. This semester was focused on digitizing order Coleoptera, with Brady digitizing and uploading 114 specimens to the database. She focused on the family Dytiscidae, zooming in on the subfamily Agabinae. Some of the more notable specimens she uploaded were a beetle found in Oaxaca (her favorite place to vacation), as well as several that were found frozen in a temperate pool. Rho concentrated on the family Anthicidae, the ant-like beetles, and uploaded 105 specimens. Over half of those specimens are Notoxus anchora, almost all of which were collected on two days in the 1980s in Burlington and Colchester, Vermont. Such abundance creates a wealth of information to draw on in future studies of Vermont’s entomological fauna and ecology. The digitization of collections enables global collaboration and further interconnectedness of natural history work by allowing global researchers to compare worldwide specimens from the past, which can be useful for understanding trends in populations and communities over time, which can translate into conserving these species. Natural history collections like the Zadock Thompson collection make disciplines like entomology and botany a science, rather than a collection of fun facts.

Mammal Collection 3D Photogrammetry Fall 2022

The 3D mammalogy project aims to create enlarged 3D models of tiny mammal skulls for use in teaching settings. Many mammal skulls and bones are too small to thoroughly identify and properly understand their respective morphological characteristics. Our team has been working to photograph these skulls and transfer the photos into a 3D modeling software, Agisoft Metashape. Our goal is to render accurate 3D models and print larger versions of them using a 3D printer. We hope to make these tools more helpful and accessible to students studying mammalogy.

      My name is Eve Phillips and I am a senior studying Biology and Reporting and Documentary Storytelling. This is my first semester working in the Natural History Collections at UVM, and this internship has quickly become one of my favorite projects I have ever worked on! I plan on continuing this project next semester in the museum.
      My name is Grace Ushay and I am a junior studying Animal Science and Wildlife and Fisheries Biology. This is my first semester interning for UVM’s Natural History collection, and I have already learned so much from working on this project!
      Led by junior Lily Duerr, this project designed procedures to clearly capture photos of the entire surface of a tiny mammal skull to then be uploaded and processed. The 3D skull photogrammetry project aims to create enlarged 3D models of small mammal skulls for use in teaching settings, specifically for UVM’s Mammalogy class lab. These models could also be used in other teaching collections like Anatomy & Physiology and Comparative Vertebrate Anatomy and Physiology. Some skulls such as the shrew or field mouse are too small to thoroughly identify and properly understand their respective morphological characteristics. Therefore, we aim to create identical models that are scaled up, less fragile, and less valuable than the original specimens. Using a macro lens camera, we took high-resolution photos of the skulls rotating around a center point from multiple angles. Powerful lights were used to pick up the miniscule details in the skulls, such as teeth, fossa, and foramen. This was perhaps the most challenging part of the project, as ensuring a smooth, uninterrupted rotation of the skulls required a stable stage and consistent lighting. Once the skulls were fully photographed, the photos were organized by angle and uploaded to Agisoft Metashape. Within this software we created masks of the skulls, removing the background of the photos entirely, and aligned tie points in the series of images to render a 3D model. Building, texturing, and aligning the different skull perspectives was also done in order to complete a continuous and authentic model. Our goal has been to render as many accurate 3D models as we can to eventually print using a 3D printer in the library. From this project we learned how to 3D render a model on the computer, and we hope to begin printing skulls next semester.
      Next semester, we are hoping to complete 3D renders for remaining skulls and begin the 3D printing process! The UVM Howe Multimedia Lab utilizes the software, Ultimaker Cura for 3D printing. Our next steps will be to transfer our models into this software and begin printing! 3D printing can be a tricky process, but we are excited to tackle the next leg of this project!

Insect Teaching Collection Fall 2022

Teaching collections give students the opportunity to see, touch, and experience specimens up close, which is especially important in entomology since insect identification requires close inspection. To that end, we are overhauling the insect teaching collection, drawing from student collections from Field Zoology classes past and ensuring each specimen is properly identified to family. We intend to prepare teaching collections for eight major orders of insects: Coleoptera, Lepidoptera, Hymenoptera, Diptera, Orthoptera, Odonata, Homoptera, and Hemiptera.

My name is Lena Heinrich and I’m a senior Zoology major with a Plant Biology minor. In the past, I’ve done behavioral ecology research with native bees and wasps, but I now study plants and I am currently applying to go to graduate school in labs that study plant-animal interactions! In the museum, I am working with James Grant, a recent graduate from UVM, to create an insect teaching collection for entomology courses at UVM. 
      For many years, students have been making insect collections as a part of these classes; to create the teaching collections, we have been sifting through these old student collections as well as materials the museum already had. Working through as many orders of insects as we can, we are picking out specimens that are in good condition, identifying them to family, and organizing them into display boxes that can be taken out and passed around in classes, giving specimens that are on pins new labels. Ultimately, we would like to have as many families represented for each order as possible to give a sense of the breadth of diversity within those groups.
I specifically worked on the Hymenoptera (bees and wasps), Lepidoptera (butterflies and moths), Odonata (dragonflies and damselflies), and Orthoptera (grasshoppers, locusts, and crickets). James is working on Diptera (flies), Hemiptera (true bugs), and Coleoptera (beetles). Hymenoptera and Lepidoptera were both very abundant in the collections, and Hymenoptera were particularly tricky to identify, so these took substantially more time. Most specimens in the teaching collection were collected in Vermont, with some boxes from South America (perhaps for a graduate student project).
      This project has allowed me to develop my insect identification skills. In the future, these teaching collections will help other students gain identification skills with insects, which are notoriously difficult and often require manipulation under a microscope or with a hand lens to assess different key characteristics such as wing venation. Because of the teaching collections, many fascinating specimens will see the light of day and be used for educational purposes that otherwise would have been hidden away on shelves and in boxes in the museum—in particular, many tropical Lepidoptera and Hymenoptera that will be novel for many students in Vermont, including bullet ants, oil- and resin-collecting bees, etc. While sifting through specimens in the museum I was also able to assess the state of specimens and begin addressing different pest issues before they became too degraded. Finally, UVM’s natural history museum has a large collection of meticulously crafted framed butterflies and moths: while sorting through these specimens, I could pick out redundant specimens that lack the necessary data to be scientifically useful, allowing the museum to use them for other purposes such as decorative displays or to sell in museum fundraisers, exposing the general public to museum specimens.
