    Research Projects Highlights:

    My area of research focuses on plant interactions with their pathogens with an especial focus on the interactions with insect pests. In addition, studies on insect pest prevalence and abundance, along with population genetic analysis will help provide the best strategies for pest elimination. By conducting studies that examine plant gene expression changes I hope to not only elucidate signaling mechanisms used by plants during defense reactions but also to identify genes to be used to in protecting plants from the stresses of pathogen attacks. These genes may come from wild relatives or other species. 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.

    Background:

    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.

    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.

We hope to gain a better understanding of how temperate fish adjust their biochemistry and physiology to compensate for long term changes in environmental temperature in the laboratory and in nature. We have also been exploring the possibility of using a cell culture model to better understand acclimation. I am also interested in the interaction of diet and temperature as they affect growth rate and development in channel catfish. We are investigating the possibility of enhancing growth at less than optimal temperatures by supplementing commercial catfish diets with various lipids. I have recently ventured into aquatic toxicology. We are currently investigating the effects of sublethal levels of manganese on the physiology of brook trout.

    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

    Research Interest:

    Dr. Taylor’s research interests are centered on immunology, specifically the immune responses and tissues in the mucosal layers of the intestine.  Recent projects have included the characterization and analysis of microscopic lymphoid tissues called cryptopatches and isolated lymphoid follicles in the small intestine of wild animals, including field mice (Peromyscus sp.) and fish (C. commersonii).  These tissues have been shown to form and change dramatically in response to diet and inflammation in laboratory animals, but little is known about cryptopatches and isolated lymphoid follicles in wild vertebrates.
    
    Another of Dr. Taylor's research interests is that of host-pathogen interactions and pathogenesis.  To that end, 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 small mammal trapping and handling, dissection and cryopreservation, tissue sectioning, histochemical staining, immunofluorescence microscopy, ELISA, PCR, and cell culture.
