  • Spatiotemporal Pattern of Phenology Across Geographic Gradients in Insects
    Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2017 Spatiotemporal pattern of phenology across geographic gradients in insects Khelifa, Rassim Abstract: Phenology – the timing of recurrent biological events – influences nearly all aspects of ecology and evolution. Phenological shifts have been recorded in a wide range of animals and plants worldwide during the past few decades. Although the phenological responses differ between taxa, they may also vary geographically, especially along gradients such as latitude or elevation. Since changes in phenology have been shown to affect ecology, evolution, human health and the economy, understanding pheno- logical shifts has become a priority. Although phenological shifts have been associated with changes in temperature, there is still little comprehension of the phenology-temperature relationship, particularly the mechanisms influencing its strength and the extent to which it varies geographically. Such ques- tions would ideally be addressed by combining controlled laboratory experiments on thermal response with long-term observational datasets and historical temperature records. Here, I used odonates (drag- onflies and damselflies) and Sepsid scavenger flies to unravel how temperature affects development and phenology at different latitudes and elevations. The main purpose of this thesis is to provide essential knowledge on the factors driving the spatiotemporal phenological dynamics by (1) investigating how phenology changed in time and space across latitude and elevation in northcentral Europe during the past three decades, (2) assessing potential temporal changes in thermal sensitivity of phenology and (3) describing the geographic pattern and usefulness of thermal performance curves in predicting natural responses.

    The Dragonflies of Bramshill Site of Special Scientific Interest Freshwater Habitats Trust Author Ken Crick Forward Bramshill Site of Special Scientific Interest (SSSI) is a Flagship Pond Site. Part of a network of the very best of Britain’s ponds; sites of exceptional importance for freshwater wildlife and some of our finest freshwater habitats. The Flagship sites can be a single special pond, or more commonly group of ponds, selected because they support rich, often irreplaceable, communities and species at risk of extinction. They represent some of the least impacted, most diverse pond habitats remaining in the country. Many of our nation’s most beautiful and biodiverse waterbodies have degraded irrevocably, and it’s critically important that the remaining sites are well protected and well managed. In 2015, with funding from the Heritage Lottery Fund, Freshwater Habitats Trust launched the Flagship Ponds project, Mats of Water Crowfoot flower on Bramshill working with land managers and community groups to ensure that the most Plantation’s Longwater. critical pond sites in Britain were protected for the long term.

(With Plate 2.) Concerning our fundamental knowledge of the Japanese fauna of dragonflies, we owe to the works of De Selys-Longchamps. His first work appeared some thirty years ago under the title „Les Odonates du Japon“ *); in this monographic list the author enumerates 67 species, of which 27 are represented by Libellulidae. This publication was followed by a second paper entitled „Les Odonates recueillis aux iles Loo-Choo“ 2),* in which 10 additional species are described , and of these 6 are Libellulidae. Needham, Williamson, and Foerster published some studies on Japanese dragonflies in several papers. Quite recently Prof. Matsumura 3) des­ cribes the dragonflies from Saghalin together with other insects occuring on that island. An elaborate work on Libellulidae is in the course of publication4), by which our knowledge on this fauna is widely extended, though I find that many species of this family are yet spared in this work. So far as I am aware, in these works are represented those Japanese dragonflies which are hitherto known. They are 48 species in number. At present our empire is greatly added in its area, so that it is extended from the high parallel of 50° north to the tropic cancer, containing those various parts of locality which are almost not yet explored.

  • ABSTRACT Gregarine Parasitism in Dragonfly Populations of Central
    ABSTRACT Gregarine Parasitism in Dragonfly Populations of Central Texas with an Assessment of Fitness Costs in Erythemis simplicicollis Jason L. Locklin, Ph.D. Mentor: Darrell S. Vodopich, Ph.D. Dragonfly parasites are widespread and frequently include gregarines (Phylum Apicomplexa) in the gut of the host. Gregarines are ubiquitous protozoan parasites that infect arthropods worldwide. More than 1,600 gregarine species have been described, but only a small percentage of invertebrates have been surveyed for these apicomplexan parasites. Some consider gregarines rather harmless, but recent studies suggest otherwise. Odonate-gregarine studies have more commonly involved damselflies, and some have considered gregarines to rarely infect dragonflies. In this study, dragonfly populations were surveyed for gregarines and an assessment of fitness costs was made in a common and widespread host species, Erythemis simplicicollis. Adult dragonfly populations were surveyed weekly at two reservoirs in close proximity to one another and at a flow-through wetland system. Gregarine prevalences and intensities were compared within host populations between genders, among locations, among wing loads, and through time. Host fitness parameters measured included wing load, egg size, clutch size, and total egg count. Of the 37 dragonfly species surveyed, 14 species (38%) hosted gregarines. Thirteen of those species were previously unreported as hosts. Gregarine prevalences ranged from 2% – 52%. Intensities ranged from 1 – 201. Parasites were aggregated among their hosts. Gregarines were found only in individuals exceeding a minimum wing load, indicating that gregarines are likely not transferred from the naiad to adult during emergence. Prevalence and intensity exhibited strong seasonality during both years at one of the reservoirs, but no seasonal trend was detected at the wetland.

  • A Survey of Odonata of the Patoka River National Wildlife Refuge and Management Area
    2012. Proceedings of the Indiana Academy of Science 121(1):54–61 A SURVEY OF ODONATA OF THE PATOKA RIVER NATIONAL WILDLIFE REFUGE AND MANAGEMENT AREA Donald L. Batema* and Amanda Bellian: Department of Chemistry, Environmental Studies Program, University of Evansville, 1800 Lincoln Avenue, Evansville, IN 47722 USA Lindsey Landowski: Mingo National Wildlife Refuge, Puxico, MO. 63960 USA ABSTRACT. The Patoka River National Wildlife Refuge and Management Area (hereafter Patoka River Refuge or the Refuge) represents one of the largest intact bottomland hardwood forests in southern Indiana, with meandering oxbows, marshes, ponds, managed moist-soil units, and constructed wetlands that provide diverse and suitable habitat for wildlife. Refuge personnel strive to protect, restore, and manage this bottomland hardwood ecosystem and associated habitats for a variety of wildlife. The Patoka River National Wildlife Refuge Comprehensive Conservation Plan (CCP) lists many species of management priority (McCoy 2008), but Odonata are not included, even though they are known to occur on the Refuge. The absence of Odonata from the CCP is the result of lack of information about this ecologically important group of organisms. Therefore, we conducted a survey, from May to October 2009, to document their presence, with special attention being paid to rare, threatened, and endangered species. A total of 43 dragonfly and damselfly species were collected and identified. No threatened or endangered species were found on the Refuge, but three species were found that are considered imperiled in Indiana based on Nature Serve Ranks (Stein 2002). Additionally, 19 new odonate records were documented for Pike County, Indiana. The results of this survey will be used by Refuge personnel to assist in management decisions and to help establish priorities for the Patoka River Refuge activities and land acquisition goals.

  • The Superfamily Calopterygoidea in South China: Taxonomy and Distribution. Progress Report for 2009 Surveys Zhang Haomiao* *PH D
    International Dragonfly Fund - Report 26 (2010): 1-36 1 The Superfamily Calopterygoidea in South China: taxonomy and distribution. Progress Report for 2009 surveys Zhang Haomiao* *PH D student at the Department of Entomology, College of Natural Resources and Environment, South China Agricultural University, Guangzhou 510642, China. Email: [email protected] Introduction Three families in the superfamily Calopterygoidea occur in China, viz. the Calo- pterygidae, Chlorocyphidae and Euphaeidae. They include numerous species that are distributed widely across South China, mainly in streams and upland running waters at moderate altitudes. To date, our knowledge of Chinese spe- cies has remained inadequate: the taxonomy of some genera is unresolved and no attempt has been made to map the distribution of the various species and genera. This project is therefore aimed at providing taxonomic (including on larval morphology), biological, and distributional information on the super- family in South China. In 2009, two series of surveys were conducted to Southwest China-Guizhou and Yunnan Provinces. The two provinces are characterized by karst limestone arranged in steep hills and intermontane basins. The climate is warm and the weather is frequently cloudy and rainy all year. This area is usually regarded as one of biodiversity “hotspot” in China (Xu & Wilkes, 2004). Many interesting species are recorded, the checklist and photos of these sur- veys are reported here. And the progress of the research on the superfamily Calopterygoidea is appended. Methods Odonata were recorded by the specimens collected and identified from pho- tographs. The working team includes only four people, the surveys to South- west China were completed by the author and the photographer, Mr.

  • The Phylogeny of the Zygopterous Dragonflies As Based on The
    THE PHYLOGENY OF THE ZYGOPTEROUS DRAGON- FLIES AS BASED ON THE EVIDENCE OF THE PENES* CLARENCE HAMILTON KENNEDY, Ohio State University. This paper is merely the briefest outline of the writer's discoveries with regard to the inter-relationship of the major groups of the Zygoptera, a full account of which will appear in his thesis on the subject. Three papers1 by the writer discussing the value of this organ in classification of the Odonata have already been published. At the beginning, this study of the Zygoptera was viewed as an undertaking to define the various genera more exactly. The writer in no wise questioned the validity of the Selysian concep- tion that placed the Zygopterous subfamilies in series with the richly veined '' Calopterygines'' as primitive and the Pro- toneurinae as the latest and final reduction of venation. However, following Munz2 for the Agrioninae the writer was able to pick out here and there series of genera where the devel- opment was undoubtedly from a thinly veined wing to one richly veined, i. e., Megalagrion of Hawaii, the Argia series, Leptagrion, etc. These discoveries broke down the prejudice in the writer's mind for the irreversibility of evolution in the reduction of venation in the Odonata orders as a whole. Undoubt- ably in the Zygoptera many instances occur where a richly veined wing is merely the response to the necessity of greater wing area to support a larger body. As the study progressed the writer found almost invariably that generalized or connecting forms were usually sparsely veined as compared to their relatives.
