    ABSTRACT CULATTA, KATHERINE EMILY. Taxonomy, Genetic Diversity, and Status Assessment of Nuphar sagittifolia (Nymphaeaceae). (Under the direction of Dr. Alexander Krings and Dr. Ross Whetten). Nuphar sagittifolia (Walter) Pursh (Nymphaeaceae), Cape Fear spatterdock, is an aquatic macrophyte considered endemic to the Atlantic Coastal Plain and of conservation concern in North Carolina, South Carolina, and Virginia. The existence of populations of unclear taxonomic identity has precluded assessment of the number of populations, distribution, and conservation needs of N. sagittifolia. Thus, the first objective of this thesis was to re-assess the circumscription of the species by evaluating four taxonomic hypotheses: 1) Populations of Nuphar in the N. sagittifolia range, including morphological intermediates, are members of a single polymorphic species; 2) Morphological intermediates in the N. sagittifolia range are hybrids between N. advena subsp. advena and N. sagittifolia; 3) Morphological intermediates are variants of N. advena subsp. advena or N. sagittifolia; 4) Intermediates, distinct from both N. advena subsp. advena and N. sagittifolia, are either disjunct populations of N. advena subsp. ulvacea or members of an undescribed taxon. The second objective was to summarize information on the taxonomy, biology, distribution, and genetic diversity of N. sagittifolia s.s to inform conservation decisions. Approximately 30 individuals from each of 21 populations of Nuphar across the N. sagittifolia range, and the type populations of N. advena subsp. advena, N. advena subsp. ulvacea, and N. sagittifolia were included in genetic and morphological analyses. Individuals were genotyped across 26 SNP loci identified for this study, and 31 leaf, flower and fruit morphological characters were measured. STRUCTURE analysis identified three genetic groups with corresponding morphological differences in the N.

The NatureServe network is more than 30 years old and shares a common conservation data methodology. The AC CDC was founded in 1997, and maintains data for the jurisdictions of New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland and Labrador. Although a non-governmental agency, the AC CDC is supported by 6 federal agencies and 4 provincial governments, as well as through outside grants and data processing fees. Upon request and for a fee, the AC CDC queries its database and produces customized reports of the rare and endangered flora and fauna known to occur in or near a specified study area.

The possi­ ble use of lady beetles to aid in the control of arthropod pests has had cosmopolitan consideration, for example, Britton 1914, Lipa and Sem'yanov 1967, Rojas 1967, and Sacharov 1915. Although prey are mainly aphids and coccids, lady beetles may also feed upon other arthropods. The biology of the family Coccinellidae has been sum- merized by Balduf 1935, Clausen 1940, Hagen 1962, and Hodek 1967. Hippodamia parenthesis and Hippodamia tredecimpunctata are two of the species of coccinellids which feed on potato infesting aphids in Maine. In attempting to determine the effect of these coccinellids on the populations of potato infesting aphids, it is necessary to know which other arthropods would serve as possible food sources. Lady beetles have certain food preferences, and the food source has an effect on de­ velopment.

  • Water Lilies As Emerging Models for Darwin's Abominable Mystery
    OPEN Citation: Horticulture Research (2017) 4, 17051; doi:10.1038/hortres.2017.51 www.nature.com/hortres REVIEW ARTICLE Water lilies as emerging models for Darwin’s abominable mystery Fei Chen1, Xing Liu1, Cuiwei Yu2, Yuchu Chen2, Haibao Tang1 and Liangsheng Zhang1 Water lilies are not only highly favored aquatic ornamental plants with cultural and economic importance but they also occupy a critical evolutionary space that is crucial for understanding the origin and early evolutionary trajectory of flowering plants. The birth and rapid radiation of flowering plants has interested many scientists and was considered ‘an abominable mystery’ by Charles Darwin. In searching for the angiosperm evolutionary origin and its underlying mechanisms, the genome of Amborella has shed some light on the molecular features of one of the basal angiosperm lineages; however, little is known regarding the genetics and genomics of another basal angiosperm lineage, namely, the water lily. In this study, we reviewed current molecular research and note that water lily research has entered the genomic era. We propose that the genome of the water lily is critical for studying the contentious relationship of basal angiosperms and Darwin’s ‘abominable mystery’. Four pantropical water lilies, especially the recently sequenced Nymphaea colorata, have characteristics such as small size, rapid growth rate and numerous seeds and can act as the best model for understanding the origin of angiosperms. The water lily genome is also valuable for revealing the genetics of ornamental traits and will largely accelerate the molecular breeding of water lilies.

Grayson, March 10, 2008 On behalf of my sisters, our mother, and the rest of our family, I want to thank you – each of you – for being here with us today to celebrate the life of a man who was incredibly dear to us and, I suspect, most of you as well. So many people have come up to us in recent years to tell us how much they admired and appreciated daddy. They’ve recounted wonderful stories that we’ve loved hearing. Almost invariably, what has come through most strongly in these stories and memories is his deep integrity, his fairness in dealing with people, and his lack of pretension. Daddy really did value people for their character and accomplishments, not for their looks or their money or their social standing. He didn’t have much truck with people who put on airs or thought overly well of themselves. He had a particularly fine sense of proportion regarding life’s values and priorities that stemmed in part, I think, from his upbringing in the mountains of Southwest Virginia. Daddy grew up on a farm near Austinville in Wythe County and, for the first eight grades, went to school in a one-room schoolhouse.

  • Lady Beetles of Nebraska
    EXTENSION EC1780 Lady Beetles of Nebraska Alexander P. Cunningham, Graduate Assistant, Entomology James R. Brandle, Professor, School of Natural Resources Stephen D. Danielson, Associate Professor, Entomology Thomas E. Hunt, Extension Entomologist EXTENSION Lady beetles are some of the most noticeable and popular insects found in the garden and on the farm. This publication will help the farmer, gardener, or amateur naturalist to better understand and identify lady beetles found in Nebraska. Biology Lady beetles are in the family Coccinellidae, of which nearly all members are predators. Most lady beetles are recognizable by their black-on-red spotted pattern and hemispherical shape (Figure 1). Other beetles, includ- Figure 1. Adult Seven-Spotted lady beetle searching for prey ing Scymnus species, are smaller and black, and are often beneficial in controlling spider mites and small insects. Lady beetles undergo complete metamorphosis, passing through the developmental stages of egg, larva, pupa, and adult. Both larvae and adults feed voraciously on aphids, mealybugs, and other soft-bodied insects. They may also feed on insect eggs, pollen, and other protein sources. Lady beetles often lay their eggs on vegetation. They deposit them upright in clusters of 5 to 50 bright yellow eggs (Figure 2). Just before hatching, the eggs darken. Once the tiny larvae hatch, they eat their eggshells, usu- ally staying clumped together for a day or so before they crawl off in search of prey. They grow in four discrete larval stages called instars, and molt between each stage. Figure 2. Lady beetle egg cluster on a leaf (photo by Dori Porter) Extension is a Division of the Institute of Agriculture and Natural Resources at the University of Nebraska–Lincoln cooperating with the Counties and the United States Department of Agriculture.
