Southeastern Mixed Forest Province 3 Why support pollinators? In theIr 1996 book, the Forgotten PollInators, Buchmann and Nabhan estimated that animal pollinators are needed for the reproduction “ Farming feeds of 90% of flowering plants and one third of human food crops. Each of us depends on these industrious pollinators in a practical way to provide us with the wide range of foods we eat. In addition, pollinators are part of the the world, and intricate web that supports the biological diversity in natural ecosystems that helps sustain our quality of life. Abundant and healthy populations of pollinators can improve fruit set we must remember and quality, and increase fruit size. In farming situations this increases production per acre. In the wild, biodiversity increases and wildlife food sources increase. that pollinators Peaches, strawberries, watermelon, and cauliflower are some of the crops raised in the Southeastern Mixed Forest that rely on honey bees and native bees for pollination. Domestic honey bees pollinate approximately $10 are a critical billion worth of crops in the U.S. each year. Unfortunately, the numbers of both native pollinators and domesticated link in our food bee populations are declining. They are threatened by habitat loss, disease, and the excessive and inappropriate use of pesticides. The loss of commercial bees to Colony Collapse Disorder (CCD) has highlighted how severe the issues of proper hive management are to reduce stresses caused systems.” by disease, pesticide use, insufficient nutrition, and transportation practices. -- Paul Growald, Currently, the pollination services that the commercial beekeeping industry provides are receiving much needed research and conservation resources. Co-Founder, The efforts to understand the threats to commercial bees should help us Pollinator partnership understand other pollinators and their roles in the environment as well. It is imperative that we take immediate steps to help pollinator populations thrive. The beauty of the situation is that by supporting pollinators’ need for habitat, we support our own needs for food and support diversity in the natural world. Thank you for taking time to consult this guide. By adding plants to your landscape that provide food and shelter for pollinators throughout their active seasons and by adopting pollinator friendly landscape practices, you can make a difference to both the pollinators and the people that rely on them.

  • APPROVED PLANT LIST Midtown Alliance Tree Well Adoption Program
    APPROVED PLANT LIST Midtown Alliance Tree Well Adoption Program Midtown Alliance launched the Tree Well Adoption program with the primary goal of enriching the experience of Midtown’s workers and residents while encouraging sustainability through the use of low-water, urban tolerant plant species. This list of plants was created to aid individuals and organizations in selecting plant material to plant in their adopted tree wells. This plant list is intended to encourage individual character in the tree wells, rather than restrict creativity in the selection of plants. The plants on the approved list were selected based on the following criteria: • Perennial. All plants listed are perennial, meaning they last for two or more growing seasons. Once established, these plants will require less water to maintain than annuals. • Heat tolerant. Plants in tree wells are exposed to high temperatures caused by vehicles and heat reflected from surrounding buildings, asphalt, and other urban surfaces. They must also be tolerant to high daytime temperatures, typical of Atlanta’s summer months, and cold hardy in the winter months. Atlanta is located in USDA Plant Hardiness Zone 7b/8a. • Water wise. Urban tree wells are surrounded by impervious surfaces and thus, are highly susceptible to periods of drought. Suitable plants must be able to survive periods of low rainfall. • Pollution tolerant. Vehicle exhaust may leave deposits and pollutants on plant foliage, which can kill sensitive plants. • Encourage wildlife. Flowering plants attract insects such as butterflies while others provide food sources for birds and other wildlife. • Grown locally. Many of the plants listed are native to the Atlanta area, and all can be found at local nurseries.

ISSN 2153 733X BARCODING THE ASTERACEAE OF TENNESSEE, TRIBE COREOPSIDEAE EDWARD E. SCHILLING, NICHOLAS MATTSON, AARON FLODEN Herbarium TENN Department of Ecology & Evolutionary Biology University of Tennessee Knoxville, Tennessee 37996 [email protected]; [email protected] ABSTRACT Results from barcoding studies of tribe Coreopsideae for the Tennessee flora using the nuclear ribosomal ITS marker are presented and include the first complete reports for 2 of the 20 species of the tribe that occur in the state, as well as updated reports for several others. Sequence data from the ITS region separate most of the species of Bidens in Tennessee from one another, but species of Coreopsis, especially those of sect. Coreopsis, have ITS sequences that are identical (or nearly so) to at least one congener. Comparisons of sequence data to GenBank records are complicated by apparent inaccuracies of older sequences as well as potentially misidentified samples. Broad survey of C. lanceolata from across its range showed little variability, but the ITS sequence of a morphologically distinct sample from a Florida limestone glade area was distinct in lacking a length polymorphism that was present in other samples. Tribe Coreopsideae is part of the Heliantheae alliance and earlier was often included in an expanded Heliantheae (Anderberg et al. 2007) in which it was usually treated as a subtribe (Crawford et al. 2009). The tribe shows a small burst of diversity in the southeastern USA involving Bidens and Coreopsis sect.

Daniel, Chair H.D. ‘Toby’ Bradshaw Janneke Hille Ris Lambers Program Authorized to Offer Degree: Biology ©Copyright 2017 Eric Octavio Campos University of Washington Abstract Plant-Pollinator Interactions in an Ecological and Evolutionary Context: The Promising Role of 3D-Printing Technology and Mathematical Modeling Eric Octavio Campos Co-Chairs of the Supervisory Committee: Professor H.D. ‘Toby’ Bradshaw Department of Biology Professor Thomas L. Daniel Department of Biology This dissertation concerns itself with the role of flower shape in affecting the foraging performance of pollinating animals. The pollinator used in this study is a model organism representing crepuscular hawkmoths in research involving the study of flight neuromuscular physiology and plant-pollinator interactions, Manduca sexta (hereafter Manduca). The broader goal of the work is to develop a new experimental framework for investigating the ecological and evolutionary consequences of plant-pollinator interactions. To that end, I have combined 3D-printing technology and mathematical modelling to construct artificial flowers, which can be manufactured with great precision and with objective, quantitatively describable shapes. First, I present a proof-of-concept study to demonstrate the feasibility of collecting foraging data from a real animal pollinator attempting to feed from 3D-printed artificial flowers. I show that Manduca’s foraging performance is extremely sensitive to variation in floral corolla curvature and nectary diameter.
