Life-History Study of Libellula Incesta with Emphasis on Egg Development As Influenced by Controlled Temperature (1971) Directed By: Dr
PITTMAN, ANNETTE ROGERS. Life-History Study of Libellula incesta with Emphasis on Egg Development as Influenced by Controlled Temperature (1971) Directed by: Dr. Paul E. Lutz. pp. 75. A field and laboratory study was carried out with Libellula incesta to investigate the effects of controlled temperature and photoperiod on egg development and to determine various aspects of the life cycle. Eggs collected from mating females were subjected to two photoperiods (11 and 14 hours) at each of six different temperatures (15, 20, 25, 30, 35, and 40°C). Libellula incesta eggs were not effected by difference in photoperiods, but total development time decreased with increases in temperature. Information concerning the life-history was obtained by sampling the larval population and field observation throughout the year. It was established that the eggs of Libellula incesta experienced direct development in about one to two weeks. In addition it was found that Libellula incesta is a univoltine summer species which overwinters in one of four instars prior to the final. Emergence began in mid-May and individuals flew until mid-October. Throughout this flight season the reproductive activity was observed. Males established territories in which they interacted with other males and mated with females. The females frequented the water only to mate and to exophytically oviposit large quantities of eggs.

In 1970 the shingle beach, now owned by the Environment Agency , was declared a Local Nature print out in booklet Reserve (LNR) by the County Council, who also appointed a form so that you can Management Committee to administer the LNR. This was the beginning of Rye Harbour Local Nature Reserve. Since then further make your own. land has been added by agreement with neighbouring landowners and the County Council and by purchase of land by the Sussex Wildlife Trust with the help of the Friends of Rye Harbour Print on both sides of Nature Reserve . It is hoped that further areas of the SSSI will become part of the Nature Reserve and so this report covers the 14 sheets of A4 paper. whole area. The present extent of the Nature Reserve includes the seaward shingle ridges extending inland to, and including, the gravel pit known as Ternery Pool and the nearby excavation known as the Quarry (Beach Reserve), a large gravel pit (Castle Water), a large area of meadow land and shingle ridges around Camber Castle (Castle Farm) and a small area of saltmarsh fringing the western bank of the River Rother between Rye Harbour and the river mouth. -
Aquatic and Terrestrial Vegetation Influence
AQUATIC AND TERRESTRIAL VEGETATION INFLUENCE LACUSTRINE DRAGONFLY (ORDER ODONATA) ASSEMBLAGES AT MULTIPLE LIFE STAGES By Alysa J. Remsburg A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy (Zoology) at the UNIVERSITY OF WISCONSIN – MADISON 2007 i ACKNOWLEDGMENTS Reflecting on the contributions of my colleagues and friends during my graduate studies gives me a strong sense of gratitude for the community of support that I have enjoyed. The people who surround and support me deserve more thanks than I can describe here. Friends and family have supported my graduate studies by generously accommodating my tight schedule and warmly offering encouragement throughout the process. Monica Turner guided my graduate studies in numerous ways. It was her trust in my abilities and willingness to learn about a new study organism that first made this research possible. She encouraged me to pursue the research questions that most interested and inspired me, although it meant charting territory that was new to both of us. Monica served as the ideal mentor for me by requiring clear communication, modeling an efficient and balanced work ethic, providing critical reviews, and listening compassionately. This research benefited from the expertise and generosity of outstanding Wisconsin ecologists. Members of my graduate research committee, Steve Carpenter, Claudio Gratton, Tony Ives, Bobbi Peckarsky, and Joy Zedler, all offered useful suggestions and critiques on experimental design, pressing research questions, and the manuscripts. Cecile Ane provided additional statistical advice and smiles. Bill Smith, Bob DuBois, and Robert Bohanan answered (or reassured me that I should try to answer) many questions about field methods, Odonata biology, and species identification. -
Adhesion Performance in the Eggs of the Philippine Leaf Insect Phyllium Philippinicum (Phasmatodea: Phylliidae)

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. -

Localizada Una Nueva Zona De Cría De Lestes Dryas Kirby, 1890 (Odonata: Lestidae) En Andalucía
Boletín Sociedad Entomológica Aragonesa, n1 36 (2005) : 262. NOTAS BREVES Localizada una nueva zona de cría de Lestes dryas Kirby, 1890 (Odonata: Lestidae) en Andalucía Francisco Jesús Cano Villegas Departamento de Ciencias Ambientales, Área de Zoología, Universidad Pablo de Olavide, 41013 (Sevilla). [email protected] Resumen: Se comunica el hallazgo de una nueva zona de cría de Lestes dryas Kirby, 1890, un odonato considerado raro en toda Europa, en Andalucía y la tercera cita de adultos para Andalucía. Palabras clave: Lestes dryas, Lestidae, Odonata, Andalucía. Lestes dryas se caracteriza por tener una distribución holártica, estando presente tanto en América del Norte como en Europa y Asia. En Europa, sus poblaciones son más escasas conforme se desciende en latitud, de forma que en la región mediterránea se encuentra principalmente en zonas montañosas (Askew, 1988). En el norte de África se ha observado sólo en zonas montañosas del Rif y el Atlas marroquí (Jacquemin & Boudot, 1999). Existen citas de L. dryas en toda la Península Ibérica, pero en la mitad sur sus poblaciones conocidas son muy escasas (Ocha- ran Larrondo, 1987). En Andalucía existen datos referentes a varias capturas de adultos realizadas a finales de la década de los setenta, las primeras observaciones corresponden a 1977 en varias charcas cercanas a El Rocío, en Huelva (Dufour, 1978); posterior- mente sólo existe otra cita en junio de 1978 en el arroyo Parrilla (La Granjuela, Córdoba) (Ferreras Romero, 1982). Asimismo hay una cita de recolección de larvas en el río Guaduares en 1988 (Villalu- enga del Rosario, Cádiz) (Jödicke, 1996). El medio fluvial no parece el habitual de las poblaciones de esta especie que, en el resto de su área de distribución, están asociadas a pozas poco profundas, charcas temporales y pequeños embalses (Askew, 1988). -

E-mail : [email protected] RÉSUMÉ.— Les Odonates de l’Oued Isser (Kabylie, Algérie) : statut et déterminants environnementaux de leur distribution.— Une étude odonatologique a été réalisée durant six mois successifs, de mai à octobre 2013 à l’Oued Isser, situé dans le nord centre algérien, une région pratiquement inexplorée auparavant. Un total de 19 espèces d’Odonates a été enregistré durant l’échantillonnage mensuel de six stations. Il est à noter la présence de Lestes numidicus et de Platycnemis subdilatata, endémiques du Maghreb. Nos résultats étendent considérablement vers l’ouest la distribution connue de L. numidicus, ayant un statut « données insuffisantes » (DD) sur la liste rouge de l’UICN. À la lumière de la présente étude, on ne propose aucun changement de la classification de la Liste Rouge de l’IUCN à l’exception de L. numidicus qui devrait être classé comme quasi menacé (NT), dans l’attente de nouvelles prospections.
