Belk, Chair Seth M. Bybee Jerald B. Johnson Steven L. Peck G. Bruce Schaalje Department of Biology Brigham Young University Copyright © 2018 Ashlee Nichole Momcilovich All Rights Reserved ABSTRACT The Evolutionary Significance of Body Size in Burying Beetles Ashlee Nichole Momcilovich Department of Biology, BYU Doctor of Philosophy Body size is one of the most commonly studied traits of an organism, which is largely due to its direct correlation with fitness, life history strategy, and physiology of the organism. Patterns of body size distribution are also often studied. The distribution of body size within species is looked at for suggestions of differential mating strategies or niche variation among ontogenetic development. Patterns are also examined among species to determine the effects of competition, environmental factors, and phylogenetic inertia. -

Aquatic Vascular Plant Species Distribution Maps
Appendix 11.5.1: Aquatic Vascular Plant Species Distribution Maps These distribution maps are for 116 aquatic vascular macrophyte species (Table 1). Aquatic designation follows habitat descriptions in Haines and Vining (1998), and includes submergent, floating and some emergent species. See Appendix 11.4 for list of species. Also included in Appendix 11.4 is the number of HUC-10 watersheds from which each taxon has been recorded, and the county-level distributions. Data are from nine sources, as compiled in the MABP database (plus a few additional records derived from ancilliary information contained in reports from two fisheries surveys in the Upper St. John basin organized by The Nature Conservancy). With the exception of the University of Maine herbarium records, most locations represent point samples (coordinates were provided in data sources or derived by MABP from site descriptions in data sources). The herbarium data are identified only to township. In the species distribution maps, town-level records are indicated by center-points (centroids). Figure 1 on this page shows as polygons the towns where taxon records are identified only at the town level.

BACKGROUND and PURPOSE In an effort to encourage the protection of native Maine plants that are naturally reduced or low in number, the State Planning Office has compiled a list of endangered and threatened plants. Of Maine's approximately 1500 native vascular plant species, 155, or about 10%, are included on the Official List of Maine's Plants that are Endangered or Threatened. Of the species on the list, three are also listed at the federal level. The U.S. Fish and Wildlife Service. has des·ignated the Furbish's Lousewort (Pedicularis furbishiae) and Small Whorled Pogonia (lsotria medeoloides) as Endangered species and the Prairie White-fringed Orchid (Platanthera leucophaea) as Threatened. Listing rare plants of a particular state or region is a process rather than an isolated and finite event. -
Aquatic Invasive Plants Information and Identification Tips
AQUATIC INVASIVE PLANTS INFORMATION AND IDENTIFICATION TIPS Alberta Lake Management Society PO Box 4283, Edmonton AB T6E 4T3 www.alms.ca INTRODUCTION This document is intended to provide an identification resource for aquatic invasive plants and encourage Alberta lake-users to watch for these species. The importance and issues associated with all aquatic plants are outlined and the implications of infestations of invasive species are discussed. We highlight four invasive aquatic plant species of concern for Alberta lakes: • Hydrilla • Curly-leafed Pondweed • Eurasian Water milfoil • Flowering Rush Detailed information on the plant is included for each species as well as a comparison between the invasive species and a similar species native to Alberta. Major distinguishing characteristics are in blue font while glossary words are underlined. If you believe you have found an invasive aquatic plant in your lake please contact us via www.alms.ca. AQUATIC VEGETATION: BENEFITS AND ISSUES What do aquatic plants do for the lake? Aquatic vegetation has many important functions within an aquatic ecosystem. Many aquatic plants provide food for fish or aquatic invertebrates, and are a key member in the food chain for these ecosystems. Many small aquatic invertebrates feed from and lay their eggs on macrophytes. In addition to food sources, aquatic plants provide shelter for young and small fish from larger predators. They are also used as spawning areas for fish and amphibians. Emergent aquatic plant such as cattails, sedges and rushes improve shoreline stability and reduce shoreline erosion. The presence of these emergent plants as well as submerged varieties, aid improving water clarity due to the binding of roots with the lake’s substrate. -

Adhesion Performance in the Eggs of the Philippine Leaf Insect Phyllium Philippinicum (Phasmatodea: Phylliidae)
insects Article Adhesion Performance in the Eggs of the Philippine Leaf Insect Phyllium philippinicum (Phasmatodea: Phylliidae) Thies H. Büscher * , Elise Quigley and Stanislav N. Gorb Department of Functional Morphology and Biomechanics, Institute of Zoology, Kiel University, Am Botanischen Garten 9, 24118 Kiel, Germany; [email protected] (E.Q.); [email protected] (S.N.G.) * Correspondence: [email protected] Received: 12 June 2020; Accepted: 25 June 2020; Published: 28 June 2020 Abstract: Leaf insects (Phasmatodea: Phylliidae) exhibit perfect crypsis imitating leaves. Although the special appearance of the eggs of the species Phyllium philippinicum, which imitate plant seeds, has received attention in different taxonomic studies, the attachment capability of the eggs remains rather anecdotical. Weherein elucidate the specialized attachment mechanism of the eggs of this species and provide the first experimental approach to systematically characterize the functional properties of their adhesion by using different microscopy techniques and attachment force measurements on substrates with differing degrees of roughness and surface chemistry, as well as repetitive attachment/detachment cycles while under the influence of water contact. We found that a combination of folded exochorionic structures (pinnae) and a film of adhesive secretion contribute to attachment, which both respond to water. Adhesion is initiated by the glue, which becomes fluid through hydration, enabling adaption to the surface profile. Hierarchically structured pinnae support the spreading of the glue and reinforcement of the film. This combination aids the egg’s surface in adapting to the surface roughness, yet the attachment strength is additionally influenced by the egg’s surface chemistry, favoring hydrophilic substrates.
