About:

Dr. Terry received his Ph.D. in Botany from the University of Wyoming in 1996. His dissertation research examined the phylogenetic relationships in Bromeliaceae (pineapple family). This was followed by postdoctoral research with Drs. Robert Nowak and Robin Tausch at the University of Nevada Reno, where he studied hybridization in Juniperus (Cupressaceae). Dr. Terry joined the Biology Department at 91自拍论坛 in 2000 following three years as a Visiting Assistant Professor at the University of Montana

Research Interests:

Research in my lab uses molecular data to examine phylogenetic relationships and hybridization in gymnosperms. Our focus since 2012 has been on relationships and species boundaries in cypresses (Cupressus/Hesperocyparis;Cupressaceae). We have also used phylogenics to examine the biogeographic history of the New World cypresses, and to assess taxonomic boundaries in the cypresses of California, a group of six species endemic to the state, some of which are threatened or endangered. Past studies have used nuclear and chloroplast DNA sequences combined with morphological features to assess hybridization in junipers. In addition to molecular phylogenetics, we sometimes conduct floristic surveys of lands of conservation concern, mostly in or adjoining the Big Thicket National Preserve.


Current Research Projects:

  1. We are studying hybridization between two species of juniper (Juniperus osteosperma and J. occidentalis) from the western United States. About 220 individuals were collected from 35 populations in Utah, Nevada, California, and Oregon during the summer of 2001. We are scoring this material for variation in growth habitat (e.g. branch number, branch angle, and plant height), reproductive (cone and seed), vegetative (leaf), and genetic (nuclear and cytoplasmic genes) characteristics. These data are being used to more clearly delimit the parental lineages and their putative hybrids from western Nevada and adjacent California.
  2. We are studying the phylogenetic relationships among the subfamilies of Bromeliaceae using DNA sequences. Sequence variation from both coding and noncoding regions of the chloroplast genome is being combined in an effort to build well-supported relationships. These data define four primary lineages in the family and provide insight into the origin of epiphytic forms of the group.
