Native Plants for Your Backyard
U.S. Fish & Wildlife Service Native Plants for Your Backyard Native plants of the Southeastern United States are more diverse in number and kind than in most other countries, prized for their beauty worldwide. Our native plants are an integral part of a healthy ecosystem, providing the energy that sustains our forests and wildlife, including important pollinators and migratory birds. By “growing native” you can help support native wildlife. This helps sustain the natural connections that have developed between plants and animals over thousands of years. Consider turning your lawn into a native garden. You’ll help the local environment and often use less water and spend less time and money maintaining your yard if the plants are properly planted. The plants listed are appealing to many species of wildlife and will look attractive in your yard. To maximize your success with these plants, match the right plants with the right site conditions (soil, pH, sun, and moisture). Check out the resources on the back of this factsheet for assistance or contact your local extension office for soil testing and more information about these plants.

Wood Anatomy of Calycanthaceae Sherwin Carlquist

Available at: http://scholarship.claremont.edu/aliso/vol10/iss3/6 ALISO 10(3), 1983, pp. 427-441 WOOD ANATOMY OF CALYCANTHACEAE: ECOLOGICAL AND SYSTEMATIC IMPLICATIONS Sherwin Carlquist INTRODUCTION Wood anatomy of Calycanthaceae has not been studied as a unit. Wood features ofthe family have been summarized by Metcalfe and Chalk (1950); various authors have mentioned one or more traits in studies dealing with Calycanthaceae (e.g., Wilson 1979) or other families (e.g., Garratt 1934). In view of recent interest in Idiospermum australiense (Diels) Blake, a new comparative study is needed. One goal of the present study is clarification of relationships of Idiospermum to Calycanthus and Chimonanthus. Wood anatomy of Idiospermum was described by Blake ( 1972) and Wilson ( 1979); a new description is offered here to provide more quantitative data. De scriptions of the wood of Calycanthus and Chimonanthus provided here incorporate such quantitative data, but also modify earlier descriptions with respect to some important qualitative features. Material of the recently de scribed genus Sinocalycanthus (Cheng and Chan 1964) was not available, although the description of that genus suggests it is not strongly different from Calycanthus or Chimonanthus. The present study incorporates material of Calycanthus floridus L. var. floridus, C. -
Eastern North American Plants in Cultivation
Eastern North American Plants in Cultivation Many indigenous North American plants are in cultivation, but many equally worthy ones are seldom grown. It often ap- pears that familiar native plants are taken for granted, while more exotic ones - those with the glamor of coming from some- where else - are more commonly cultivated. Perhaps this is what happens everywhere, but perhaps this attitude is a hand- me-down from the time when immigrants to the New World brought with them plants that tied them to the Old. At any rate, in the eastern United States some of the most commonly culti- vated plants are exotic species such as Forsythia species and hy- brids, various species of Ligustrum, Syringa vulgaris, Ilex cre- nata, Magnolia X soulangiana, Malus species and hybrids, Acer platanoides, Asiatic rhododendrons (both evergreen and decidu- ous) and their hybrids, Berberis thunbergii, Abelia X grandi- flora, Vinca minor, and Pachysandra procumbens, to mention only a few examples. This is not to imply, however, that there are few indigenous plants that have "made the grade," horticulturally speaking, for there are many obvious successes. Some plants, such as Cornus florida, have been adopted immediately and widely, but others, such as Phlox stolonifera ’Blue Ridge’ have had to re- ceive an award in Europe before drawing the attention they de- serve here, much as American singers used to have to acquire a foreign reputation before being accepted as worthwhile artists. Examples among the widely grown eastern American trees are Tsuga canadensis; Thuja occidentalis; Pinus strobus (and other species); Quercus rubra, Q. palustris, and Q. -

Relative Resistance Or Susceptibility of Landscape-Suitable Elms (Ulmus Spp.) to Multiple Insect Pests
236 Potter and Redmond: Elm Resistance to Insect Pests Arboriculture & Urban Forestry 2013. 39(5): 236–243 Relative Resistance or Susceptibility of Landscape-suitable Elms (Ulmus spp.) to Multiple Insect Pests Daniel A. Potter and Carl T. Redmond Abstract. The National Elm Trial is a cooperative project to assess landscape suitability of Dutch elm disease-resistant elms (Ulmus spp.) in various regions of the United States. Researchers evaluated 20 cultivars of American, Asian, and hybrid elms for relative resistance or susceptibility to multiple insect pests in central Kentucky over seven years. Ratings for Japanese beetle, European elm flea weevil (EEFW), and several other pests were previously published. This paper reports data for seven additional pests, including honeydew-excreting scale insects (Parthenolecanium corni, Eriococcus spuria, and Pulvinaria innumerabilis), leaf-distorting woolly elm and woolly apple aphids (Eriosoma spp.), elm cockscomb gall aphid (Colopha ulmicola), and an invasive weevil (Oedophrys hilleri) not previously known to damage elms. Rankings for all 12 of the monitored pests are summarized. Most U. americana cultivars were relatively susceptible to the scale insects and likewise, Eriosoma spp. and C. ulmicola only infested the American elms. O. hilleri is a new state record for Kentucky. Its adults, active in mid- to late summer, chewed notches in edges of leaves. Cultivars of the Asian species U. parvifolia and U. propinqua, including ‘Athena Classic Lacebark’, ‘Everclear Lacebark’, ‘Emer II Allee’, and ‘Emerald Sunshine’ were top-rated for insect resistance. They were nearly pest-free except for foliar damage by EEFW, to which nearly all elms were susceptible. Insect resistance should be considered when re-introducing elms to urban landscapes. -
Sociality in Caterpillars: Investigations Into the Mechanisms Associated with Grouping Behaviour, from Vibroacoustics to Sociogenomics
Sociality in Caterpillars: Investigations into the Mechanisms Associated with Grouping Behaviour, from Vibroacoustics to Sociogenomics by Chanchal Yadav A thesis submitted to the Faculty of Graduate and Postdoctoral Affairs in partial fulfillment of the requirements for the degree of Doctorate of Philosophy in Biology Carleton University Ottawa, Ontario © 2020, Chanchal Yadav Abstract Social grouping is widespread among larval insects, particularly in a number of phytophagous larval Lepidoptera (caterpillars). Although the benefits of social grouping are widely recognized, the proximate mechanisms mediating grouping behaviour, such as group formation and maintenance, are poorly understood. My Ph.D. thesis takes a pioneering approach to understanding these mechanisms, specifically, by studying the roles of vibroacoustics and sociogenomics, using the masked birch caterpillar, Drepana arcuata (Lepidoptera: Drepanoidea), as a model. There are two main objectives of my thesis - (i) to test the hypothesis that caterpillars employ plant-borne vibratory signals to recruit conspecifics to social groups; and (ii) to test the hypothesis that differential gene expression is associated with developmental transitions from social to solitary behavioural states. For the first objective, I documented morphological and behavioural changes in the larvae, showing that there are five larval instars, and developmental changes in social and signalling behaviour. Specifically, early instars (I, II) live in small social groups, and late instars (IV, V) live solitarily, with third instars (III) being transitional. Instars I-III generate four signal types (AS, BS, MS, MD), instars IV, V generate three signals (AS, MS, MD). I then used an experimental approach to test if early instars employ vibrations during social recruitment, and found that vibratory signals are used to advertise feeding and silk shelters, leading to recruitment, with higher signalling rates resulting in faster joining times by conspecifics. -
