    Research Interests:

    I am primarily interested in how population level processes scale up to the community, as well as related evolutionary drivers. Much of my work centers around how individual and species-specific behaviors, coupled with resource availability, influence niche breadth, overlap, and coexistence. I also apply these questions to urban and agricultural systems to mitigate human-wildlife conflicts and limit the spread of zoonotic diseases. I have a passion for data analysis and use a range of modeling techniques to understand these phenomena.

  • Additional Information

    I have a B.S. & a M.S. in Zoology from the University of Wisconsin-Oshkosh, I received my Ph.D. in 2004 from the University of Toronto. Since completing my Ph.D. I was a post-doc with the Smithsonian Tropical Research Institute, a postdoctoral teaching & research associate at the University of Nevada-Las Vegas and a teaching fellow at the University of Virginia's College at Wise. Since 2008 I have been an assistant professor of biology here at Frostburg State University.

    Courses Taught:

    Throughout my career I have taught a wide range of courses ranging from introductory biology to field ecology to graduate level statistical analysis classes. Currently the main courses I teach are Mammalogy, Animal Behavior and non-majors introductory biology.

    Research Project Highlights:

    My research has largely focused on small mammal ecology. Specifically how anthropogenic changes in habitat structure impact small mammal community structure and in turn how changes in small mammal community structure can impact overall biodiversity through changes in seed predation and seed dispersal. Largely these projects have been conducted in the Tropics, with past research being done in Panama, Venezuela & Brazil. However my interests are not limited to the tropics and I am activity seeking to conduct more research in temperate regions. Additionally I am not only interested in small mammals but have recently begun several projects looking at deer browsing and the potential impacts of coyotes on deer populations.

    Research Interest:

    My research interests include:

    -Study of Mesozoic and Paleozoic fossil plants in tracing the origin of flowering plants

    -Study of both living and fossil Carnivorous Plants with their morphology, ecology, and origin
    Other biological studies, from interested molecules (using GC-MS and THertz Spectroscopy) to plant therapeutical properties

    - Other biological studies, from interested molecules (using GC-MS and THertz Spectroscopy) to plant therapeutical properties.

    Paleobotanic Research Interests:

    My research interests are mainly focused on the "origin of angiosperms" that has been an "abominable mystery" since Darwin. Currently, we still do not know when, where, and from which plants the flowering plants originated, while the confirmed, earliest angiosperm megafossils are 125 million years old, found from the Yixian Formation, Lower Cretaceous, Liaoning, northeastern China.

    I have published three papers on three different fossil flowering plants found from the Yixian Formation, including Archaefructus eoflora (Ji et al., 2004), Archaeamphora longicervia (Li, 2005) and Hyrcantha decussata (Dlicher et al., 2007). Considering that angiosperms had highly diversified during the Early Cretaceous, the origin of angiosperms must be much earlier.

    To trace the possible PreCretaceous angiosperms, I am applying two approaches, studying the plant morphology and anatomy and analyzing fossil molecules from 1) angiosperms collected form the Yixian Formation of the Early Cretaceous, northeastern China; 2) possible angiosperm fossil plants collected form the Middle-Late Jurassic, northeastern China; 3) fossil plants that have some angiosperm characteristics, collected form the Late Triassic- Early Jurassic, northern and southern China; and 4) Permian gigantopterids (250-290 million years ago) from China and USA.

    I have been studying Chinese gigantopterids since 1983 and found their morphology (e.g., broad leaves, complex reticulate venation) and anatomy (e.g., paracytic stomata, vessels. 1996 Science) make them resemble angiosperms the most among all living and fossil seed plants, and their Permian age well matches the origin time of angiosperms suggested by molecular clock studies (see my gigantopterid-related-papers published in 1990, 1994, 1996, 1998, and 1999). However, because the confirmed earliest angiosperms are only about 125 million years old, I have been hesitating to further correlate gigantopterids with angiosperms, unless I obtain some more convincing evidence.

    Because there is no DNA or RNA preserved in PreCretaceous fossil plants, we have to use other stable fossil molecules to trace lineage of angiosperms. Oleanane appears to be an ideal angiosperm biomarker because it has been found in most angiosperm families, and its increase matches well with the diversification of flowering plants during Cretaceous.

    From the Yixian Formation, I have reported a species flowering plant, Archaefructus eoflora (Ji et al., 2004). More excitingly, I also have found fossil pitcher plants from the same place in the same fossil flora (Li, 2005). The fossil pitcher plants of Archaeamphora longicervia share many characteristics with modern sarraceniacean pitcher plants of America. Since Sarraceniaceae are placed within the crown group of angiosperms, the discovery of the sarraceniacean-like fossil pitcher plants suggests the basal angiosperms should have originated much earlier, possibly as 280 million years ago as recent molecular clock studies suggested. I have found oleanane from the Chinese gigantopterids of Permian (Taylor et al., 2006, Paleobiology 32(2): 179-190). Nature editor Dr. Henry Gee pointed out that, "If they (gigantopterids) are found to be closer to the flowering plants, the lineage leading to flowering plants will be put securely back into the Permian period" (http://www.nature.com/nsu/991209/991209-8.html).

    Carnivous Plants Research Interests:

    The Archaeamphora longicervia found from the Lower Cretaceous is actually a fossil pitcher plant that shares many morphological and anatomical characteristics with modern sarraceniacean pitcher plants of America (Li, 2005). This conclusion is also supported with the discovery of angiosperm biomark molecule oleanane from Archaeamphora specimens. Since Sarraceniaceae are placed within the crown group of angiosperms, this is the earliest fossil record of carnivorous plants and the earliest fossil record of crown group of angiosperms.

    My discovery of fossil pitcher plant Archaeamphora also inspired my interests in study of modern carnivorous plants, including their origin, phytogeography, morphology, ecology, conservation, and molecular as well as medicinal studies. I had one graduate student complete his master degree research on a comprehensive investigation of local populations of Sarracenia purpurea. Beside these, I have organized the 6th Conference of International Carnivorous Plant Society, hosted at Frostburg State University, June 1-5, 2006.

    Other Biological Studies:

    When I was working on modern pitcher plants and trying to find out some special molecules that could be used as specific biomarkers, I found many of them yield mocule plumbagin that have studied as a potential anticancer agent. That lead me to further expanded my research into examine plumbagin and other molules, with a new technology, T-Hertz Spectrascopy, and ended with several publications.

    Therefore, I study not only fossil plants, but also modern plants. In particular, when I cannot find some morphology/anatomy of a modern plant from literature, I will dissect the plant and use my own observation to clarify some characteristics in related fossil plants. For example, when I study the earliest, anatomically preserved fossil cycad, I dissected living cycad material to obtain a comprehensive understanding of anatomy of cycads. These studies may lead to important discoveries to clarify some evolutionary problems.

    Research Interest:

    As a researcher, I am interested in studying pathogenicity, antibiotic resistance and molecular characteristics of clinically important bacteria to understand their natural ability of transferring extrachromosomal genetic elements. My research findings will help us to understand large-scale questions about bacterial mutations and multidrug resistance of the fast-emerging bacteria. I work on real time PCR products and analyze them by agarose gel electrophoresis and DNA Sequencing in which amplification of DNA is performed using the Dideoxynucleotide method with an AmpliTAQ FS Big Dye Terminator cycle sequencing kit and ABI Prism 310 genetic analyzer. Phylogenetic trees are constructed based on maximum likelihood, and the GenBank database with BLAST is used to identify phylogenetically close relatives of isolated bacteria.

    Research Projects Highlights:

    Most recently my research has moved to the genetic and chemical profiling of hemp (Cannabis sativa). A great team of undergraduate students and I are cataloging microsatellite profiles of hemp varieties along with correlating those to CBD, THC, terpene and other cannabinoid levels. In addition to hemp, my research also focuses on plant interactions with their pathogens with a special focus on the interactions with insect pests. One specific plant pest that is of interest is whiteflies. These phloem feeding insects remove photoassimilates along with vectoring viruses. The long-term goal of experiments will be to breed and create plant germplasm that is resistant to or tolerant of these devastating pests.

    A large portion of Dr. Serfass's research and conservation activities have focused on the design, implementation, and evaluation of wildlife restoration programs and recovering wildlife populations—particularly mesocarnioves. Tom conceived and coordinated the successful Pennsylvania River Otter (Lontra canadensis) and Fisher (Martes pennanti) Reintroduction Projects, and has authored over 40 journal, proceedings, popular articles, and book chapters dealing specifically about river otters, fishers, and wildlife reintroductions. During the past 14 years Tom has mentored the completion of 38 MS and PhD students, conducting research ranging from evaluating the fates of river otters reintroduced in western New York to assessing the natural history and conservation value (potential as flagship species) of spotted-necked otters (Lutra maculicollis) and other wildlife at Rubondo Island National Park, Lake Victoria, Tanzania. Tom is the North American Coordinator of the International Union for the Conservation of Nature and Natural Resources’ Otter Specialist Group.

    Note: Tom is not currently accepting new graduate students except for those with an international research interest in carnivore conservation and having funding to support those interests.

    Research Interest:

    Ecological parasitology, plastics ecology, and their interactions in natural systems. I am interested in understanding the roles that both parasites and plastic pollution play in shaping the trophic relationships of organisms in freshwater, estuarine, and marine systems. Much of the research I conduct is collaborative in nature, and employs sophisticated taxonomic, biochemical, and spatio-statistical methods to learn about the ways that our planet is changing. I often work on avian-parasite systems, with particular emphasis on waterbirds that live in freshwater, coastal, and pelagic systems.

    Special Topics: Host-Pathogen Interactions


    Dr. Taylor's research interests are centered on immunology, especially host-pathogen interactions and mucosal immunology. Currently, Dr. Taylor and several undergraduate and graduate students are currently investigating the prevalence of Borrelia burgdorferi, the causative agent of Lyme disease, in Western Maryland. Ticks are collected and tested for the presence of Borrelia by PCR analysis, and blood and tissue samples from wild mice are also tested by ELISA and PCR. These data along with environmental information will allow a broad picture of the emergence of Lyme in the regional area.

    Dr. Taylor mentors undergraduate and graduate students who have an interest in learning advanced biological techniques such as fluorescence microscopy, scanning electron microscopy, dissection and cryopreservation, tissue sectioning, histochemical staining, ELISA, PCR, and cell culture.

    My current research focuses on rare plants and ecosystems throughout Appalachia and the mid-Atlantic region. I have strong interests in the biogeography and evolutionary ecology of insular ecosystems and endemic plant species, as well as the resilience of these biodiversity hotspots towards anthropogenic impacts, shifts in disturbance regime, and climate change.
