The Natural Science Research Laboratory (NSRL) is a division of the Museum of Texas Tech University committed to the mission of building and preserving a library of our planet's natural heritage for education and research purposes. The NSRL has been recognized as a leader in the development and use of innovative methodologies for biological collections care and data management.

The NSRL maintains four major natural history collections:  Mammals, Birds, Invertebrates, and Genetic Resources.  These collections are available to researchers at academic, scientific, and government institutions around the world for scientific investigation, discovery, and problem-solving in the natural sciences.  The causes and impacts of animal-borne diseases, parasites, climate change, habitat loss, geographic isolation, and natural evolutionary processes and speciation are just a few examples of the investigations that can be conducted utilizing specimens and tissues archived in the NSRL's collections.  Further, the resources of the NSRL are utilized by the academic and scientific communities to train and educate students at the undergraduate and graduate levels for careers in the natural sciences as well as museum science.  


March 2024  The Spring 2024 edition of NSRL News is now available!  Check it out for updates on the latest NSRL happenings.

March 2024  The NSRL Ornithology Collection database is now available online. Dr. Nancy McIntyre, Curator of Ornithology, and Ashley Kempken, former graduate student in the Museum Science Program at the Museum of Texas Tech, in collaboration with NSRL Curator of Collections Heath J. Garner and Curator of Invertebrate Zoology Dr. Jennifer C. Girón, made the records of the Ornithology Collection available online through the portal Consortium of Small Vertebrate Collections (CSVColl) and the Global Biodiversity Information Facility (GBIF). The data can also be searched through the NSRL vertebrate database. More than 6,000 records of birds, with an emphasis on Texas species, are now publicly available.

September 2023 We are pleased to announce that Dr. Jennifer Girón has been appointed as the NSRL's Curator of Invertebrate Zoology!  In her previous part-time position as Acting Collections Manager, Jennifer was already performing many important duties in the Collection, including processing incoming and outgoing loans, digitizing the collection, supervising student workers, and conducting outreach and engagement activities.  Her appointment as Curator fills a vital role at the NSRL and the Museum, and we are excited for the future of the collection in terms of its on-going care, enhancement, research potential, and education and outreach value with Jennifer as Curator.  The Invertebrate Zoology Collection is in good hands!

July 2023  Dr. Jennifer Girón, Acting Collections Manager of the Invertebrate Zoology Collection coauthored a paper describing 38 new species of Neotropical water scavenger beetles. The paper is published in the Open Access journal ZooKeys:  Short AEZ, Girón JC (2023) Revision of the Neotropical water scavenger beetle genus Novochares Girón & Short (Coleoptera, Hydrophilidae, Acidocerinae). ZooKeys 1171:1-112. https://doi.org/10.3897/zookeys.1171.104142.  Seventeen specimens included in this taxonomic revision (eight of them paratypes), are now housed at the Invertebrate Zoology Collection. Their data can be accesed via ecdysis.

June 2023  After ten years of managing the specimen data of the Invertebrate Zoology Collection via the SCAN (Symbiota Collections of Arthropods Network) portal, we have moved to the Symbiota ecdysis portal for day-to-day digitization activities. The data available in ecdysis include all the past records that were available in SCAN. Ecdysis has additional functions and tools that make data entry and management easier and more efficient. You can find our most up-to-date database at https://ecdysis.org/collections/misc/collprofiles.php?collid=80. The data available in SCAN will be updated monthly.

May 2023  Did you know?  A few years ago, NSRL curators, staff, and students, with help from others on campus, led the efforts to establish The Arroyo at the front of the Texas Tech Museum.  This naturalized landscape of native plants was designed to mimic the arroyo habitats that are typical along the caprock of the Llano Estacado.  The Museum Arroyo includes signage about Llano Estacado habitats, plants, and wildlife.  Not only an attractive and educational component of the Museum entrance, the arroyo also functions as natural habitat for a great diversity of native invertebrate species, including pollinator species that are such critical components of an ecosystem, as well as birds.  NSRL volunteers Carl Seaquist and Catherine Galley, who work tirelessly to maintain the arroyo by removing non-native plants and clearing out debris, have been documenting the plants and the invertebrates of the Arroyo and the surrounding Museum grounds on two iNaturalist pages, https://www.inaturalist.org/projects/ttu-museum-plants and https://www.inaturalist.org/projects/ttu-museum-invertebrates-lubbock-tx.  iNaturalist is a citizen-science website that allows people, world-wide, to post their photographic observations of biodiversity and to share them with fellow naturalists and the research community.  Similarly, Catherine is involved in documenting the biodiversity of the Lubbock Lake Landmark at their iNaturalist site, https://www.inaturalist.org/projects/lubbock-lake-landmark.  Check out the sites, and join the effort by posting your photos and identifications!

April 2023   Students who have been working with specimens and samples housed at the NSRL presented their research projects at the 2023 Texas Tech University Undergraduate Research Conference. Representing the Invertebrate Zoology Collection: Trier Hodge (Senior Student, Department of Biological Sciences), Sofia Rodriguez (First Year Student, Plant and Soil Science Department), and Joshua Winsauer (Third Year Student, Department of Natural Resources Management). Rodriguez got the First Place Impact Award in the Energy and Environment category.  Representing the Mammal Collection and Dr. Bradley's laboratory in Biological Sciences: Georgina Brugette, Madison Reddock, and Savannah Ticknor.

March 2023  Students in the Department of Biological Sciences and Research Associates of the NSRL at the Museum of Texas Tech published new research in the journal Insectes Sociaux. Using whole-genome data to study relatedness in three species of North American carpenter ants (genus Camponotus), researchers found that in these species members of the same colony are full sisters, which indicates that colonies are founded by one, single-mated queen. These results are supported by mtDNA data, allele frequency-free methods, and allele frequency-dependent methods. Specimens from the colonies used in this study are now housed at the Invertebrate Zoology Collection. The complete paper is available open access at: https://doi.org/10.1007/s00040-023-00906-7.

February 2023  Texas Tech students conducting NSRL-based research had a very good showing at the annual meeting of the Texas Society of Mammalogists, held 10-12 February 2023 at the TTU Center at Junction.  Danielle Deming, a Master's student of Dr. Warren Conway (conducting her research in the lab of Dr. Robert Bradley), won the TSM award for her oral presentation, “Coyote population estimation in the Mojave Desert region using noninvasive genetic sampling.”  Isham Azhar, a Master's student of Dr. Tigga Kingston (conducting his research in the lab of Dr. Caleb Phillips), won the Vernon Bailey Graduate Award for his poster, “Functional diversity of forest interior insectivorous bat communities decreases following forest fragmentation.”  And Sufia Neha, a Master's student of Dr. Bradley, won the Clyde Jones Graduate Award for her poster, “The effect of host phylogeny and diet on the rodent gut microbiome.”  In addition, Emily Wright, PhD candidate in the lab of Dr. Bradley, won the Mammal Challenge quiz!  Congratulations to all!

January 2023  On January 11, the NSRL marked its 50-year anniversary (1973–2023) with a celebration at the Museum.  The event included presentations by Dr. Robert D. Bradley, Director of the NSRL, and guest speaker Dr. Rodney L. Honeycutt, Professor Emeritus, Pepperdine University.  A report about the NSRL's 50 years of contributions in research, education, scholarship, collections growth and management, and engagement also was produced, as well as a timeline of the history of the NSRL.  The NSRL extends a warm thank you to those who attended, and to all of our additional friends, supporters, and colleagues who have helped make the NSRL a successful and productive program.  We look forward to the next 50 years and beyond!

December 2022  Collaborative research by Dr. Robert D. Bradley, Director of the NSRL, Dr. Daniel M. Hardy of the Department of Cell Biology and Biochemistry at TTUHSC, two of Bradley's graduate students (Emma Roberts, now a post-doc in Dr. Bradley's lab and Emily Wright, PhD candidate), and Steve Tardif, a post-doc in Hardy's lab, was recently featured in the TTUHSC "Daily Dose", https://dailydose.ttuhsc.edu/2022/november/gene-evolution-research-genome-biology.aspx.  The article highlights the recent publication by Roberts et al. in Genome Biology https://genomebiology.biomedcentral.com/articles/10.1186/s13059-022-02721-y about their discovery of the first known prezygotic speciation gene (zonadhesin) in mammals. This research investigates the origin of a speciation gene across vertebrates, integrating a wide breadth of tissues from the NSRL. The team is also characterizing zonadhesin's role in speciation among mammals at different stages of divergence (older species, sister taxa, and hybrid individuals).

December 2022 On 9 December, during the Third (Virtual) Symposium and Annual General Meeting of The Coleopterists Society, undergraduate student Shelby Hernandez and Acting Collections Manager Dr. Jennifer Girón presented talks about their beetle-related projects. The talks are available for viewing:


September 2022 On 13 September, the Museum and Texas Tech University Press hosted a book signing and presentation, open to the public, to celebrate the release of Texas Natural History in the 21st Century, authored by alumni and former TTU President Dr. David J. Schmidly, NSRL Director Dr. Robert D. Bradley, and NSRL Research Associate Lisa C. Bradley.  This book is a second, significantly updated, edition of Texas Natural History: A Century of Change (2002), and tells the story of Texas' biodiversity, current conservation challenges, and potential solutions to those challenges.  The well-attended event included a presentation by Dr. Schmidly and Dr. Bradley and a tour of the Museum's exhibit hall, "Biodiversity of the Llano Estacado."  Books were available for sale by TTU Press, and can be purchased online here.  


July 2022 Research Associates of the Natural Science Research Laboratory (NSRL) at the Museum of Texas Tech published new research on carpenter ants and their endosymbionts. Endosymbionts are microorganisms that live inside other organisms, and in many cases helping their hosts obtain nutrients. The team studied the effect of the demography and evolutionary history of the host ants on the molecular evolution of their endosymbionts. Representative specimens from the ant colonies used in this study are now housed at the Invertebrate Zoology Collection of the Museum of Texas Tech. The paper was published in the journal Ecology and Evolution and authored by Dr. Joseph Manthey, professor of the Biology Department at TTU, Jack Hruska, doctoral candidate of the Biology Department at TTU, and Dr. Jennifer Girón, acting collections manager of the Invertebrate Zoology Collection of the Museum of Texas Tech. The complete paper is available open access at: https://doi.org/10.1002/ece3.9026
