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. -

E-mail: [email protected] 4Corresponding author: [email protected] Abstract A new genus and species of damselfly, Burmagrion marjanmatoki, gen. et sp. nov., is described from Early Cretaceous Burmese amber. It is attributed to the basal stem group of Coenagrionoidea. The inclusion of five wings from the same species suggests that the amber piece contains the remains of a mating pair of damselflies. Key words: damselfly, Coenagrionoidea, fossil insect, Cenomanian Introduction Even though numerous Odonata have been described from Cretaceous sedimentary deposits, including representatives from at least 16 families from the Lower Cretaceous Santana Formation in Brazil (Bechly 1996a, 1998b, 2007, 2010) and numerous taxa from Lower Cretaceous deposits in England (Jarzembowski et al. 1998) and France (Nel et al. 2008), and even though odonate fossils are well represented in Tertiary amber (Bechly 1993, 1996b, 1998a, 2000; Bechly & Wichard 2008), descriptions of damselflies in Cretaceous amber were very rare until the recent boom of paleoentomological studies on Burmese amber. -
Quadratum Selys, with a Key to Theknown Larvae
Odonatologica 38(4): 321-328 December 1, 2009 Description of thelarva of Acanthagrion quadratum Selys, with a key to theknown larvae of the genus (Zygoptera: Coenagrionidae) R. Novelo-Gutiérrez Systematics Network, Institute de Ecología, A.C., Apartado Postal 63, MX-91070 Xalapa,Veracruz, Mexico [email protected] Received 18 August 2009 / Reviewed and Accepted 5 September 2009 The larva is described, illustrated, and compared with other described congeneric larvae. A. quadratumis distinguished from all others by possessing 3 premental setae, 4 setae on labial palp, and caudal lamellae 8-10 times longer than their widest part. A key tothe 9 known congeneric larvae is provided INTRODUCTION The neotropical genus Acanthagrion Selys, 1876 comprises 40 known species ELLENRIEDER & (VON LOZANO, 2008), A. inexpectum Leonard and A. quadratum Selys occur in Mexico (GONZAlEZ-SORIANO & NOVELO-GU- TIERREZ, 2007). The genus was redefined by VON ELLENR1EDER & LOZ- ANO (2008), who diagnosed the larvae from those of Oxyagrion by their markedly lanceolate caudal lamellae, with width/length ratio 0.18 or less, and longer than abdomen (1.02 or more). Despite the speciose nature of the genus, larvae of only eight species (20% of genus) have been described: A. ascendens Calvert (GEIJS- KES, 1941), A. adustum Williamsonand A. indefensum Williamson(GEIJSKES, 1943), A. fluviatile De Marmels (DE MARMELS, 1990), A. apicale Selys (DE MARMELS, 1992), A. hildegarda Gloger (MUZON et al. 2001), A. vidua Selys (DE MARMELS, 2007), and A. aepiolum Tennessen (LOZANO et al., 2007). WESTFALL & MAY (1996) keyed the larva of A. quadratum, providing some but did include figures, not a description. -

Biogeography of Dragonflies and Damselflies: Highly Mobile Predators
14 Biogeography of Dragonflies and Damselflies: Highly Mobile Predators Melissa Sánchez-Herrera and Jessica L. Ware Department of Biology, Rutgers The State University of New Jersey, Newark Campus, USA 1. Introduction Dragonflies (Anisoptera) damselflies (Zygoptera) and Anisozygoptera comprise the three suborders of Odonata (“toothed ones”), often referred to as odonates. The Odonata are invaluable models for studies in ecology, behavior, evolutionary biology and biogeography and, along with mayflies (Ephemeroptera), make up the Palaeoptera, the basal-most group of winged insects. The Palaeoptera are thought to have diverged during the Jurassic (Grimaldi and Engel, 2005; Thomas et al., 2011), and as the basal-most pterygote group, odonates provide glimpses into the entomological past. Furthermore, few other insect groups possess as strong a fossil record as the Odonata and its precursors, the Protodonata, with numerous crown and stem group fossils from deposits worldwide. Their conspicuous behavior, striking colors and relatively small number of species (compared to other insect orders) has encouraged odonatological study. Odonates are important predators during both their larval and adult stages. They are often the top predators in freshwater ecosystems, such as rivers and lakes. One of their most remarkable traits, however, is their reproductive behavior, which takes place in a tandem position with the male and female engaging in a “copulatory wheel” (Fig. 1). Fig. 1. Odonata copulatory wheel (modified from Eva Paulson illustration Aug, 2010). www.intechopen.com 292 Global Advances in Biogeography During the last 5 decades, our understanding about the ecology and evolution of Odonata has increased dramatically (e.g., Cordoba-Aguilar, 2008). A fair odonate fossil record coupled with recent advances in molecular techniques, have inspired several biogeographical studies of Odonata. -

E-mail: [email protected] Abstract Drepanosticta machadoi sp. nov. (Holotype ♂: Dablin Creek, Hindenburg Range) from Papua New Guinea is described. The new species is a predominantly black damselfly, the male with four pale/bright pattern elements on each side of the synthorax, dorsum of segments 9 and 10 largely bright blue, and a uniquely shaped posterior lobe of the pronotum which is a wide-angled fork with rather straight, narrow finger-like prongs. It is referred to the Drepanosticta conica group of species and a key to the males of the D. conica group is provided. Key words: Odonata, damselfly, Platystictidae, Drepanosticta, New Guinea, new species, key Introduction Sixteen species of the platystictid genus Drepanosticta Laidlaw, 1917, are known from the island of New Guinea. They were described by Selys (1878), Martin (1909), Laidlaw (1917), Lieftinck (1932, 1938, 1949), and Theischinger & Richards (2005, 2014). -

An Overview of Molecular Odonate Studies, and Our Evolutionary Understanding of Dragonfly and Damselfly (Insecta: Odonata) Behavior
International Journal of Odonatology Vol. 14, No. 2, June 2011, 137–147 Dragons fly, biologists classify: an overview of molecular odonate studies, and our evolutionary understanding of dragonfly and damselfly (Insecta: Odonata) behavior Elizabeth F. Ballare* and Jessica L. Ware Department of Biological Sciences, Rutgers, The State University of New Jersey, 195 University Ave., Boyden Hall, Newark, NJ, 07102, USA (Received 18 November 2010; final version received 3 April 2011) Among insects, perhaps the most appreciated are those that are esthetically pleasing: few capture the interest of the public as much as vibrantly colored dragonflies and damselflies (Insecta: Odonata). These remarkable insects are also extensively studied. Here, we review the history of odonate systematics, with an emphasis on discrepancies among studies. Over the past century, relationships among Odonata have been reinterpreted many times, using a variety of data from wing vein morphology to DNA. Despite years of study, there has been little consensus about odonate taxonomy. In this review, we compare odonate molecular phylogenetic studies with respect to gene and model selection, optimality criterion, and dataset completeness. These differences are discussed in relation to the evolution of dragonfly behavior. Keywords: Odonata; mitochondrion; nuclear; phylogeny; systematic; dragonfly; damselfly Introduction Why study Odonata? The order Odonata comprises three suborders: Anisozygoptera, Anisoptera, and Zygoptera. There are approximately 6000 species of Odonata described worldwide (Ardila-Garcia & Gregory, 2009). Of the three suborders Anisoptera and Zygoptera are by far the most commonly observed and collected, because there are only two known species of Anisozygoptera under the genus Epiophlebia. All odonate nymphs are aquatic, with a few rare exceptions such as the semi-aquatic Pseudocordulia (Watson, 1983), and adults are usually found near freshwater ponds, marshes, rivers (von Ellenrieder, 2010), streams, and lakes (although some species occur in areas of mild salinity; Corbet, 1999). -

E-mails: [email protected]; [email protected] Abstract The development of the nymphal stages of Acanthagrion viridescens Leonard was examined under laboratory conditions. Based on specimens collected in Minas Gerais state (Brazilian Southeastern Region), we described and illustrated the last- instar nymph and illustrated the egg and other nymphal stages. The nymphs of A. viridescens went through 11 instars, each of them with an average duration of approximately 13 days. The combinations of the following characteristics distinguish the last-instar nymph of A. viridescens from congeners: prementum with 2+1 setae in each side; labial palp with six apical denticles; mandibular formula L 1+2 3 4 5 y a, R 1+2 3 4 5 y- a b; presence of trifid spine in the ventral distal region of the tibia and in the tarsi; format of the male and female gonapophyses; and the distinctive pattern of the tracheae in the caudal gills. This also represents the first record of this species from southeastern Brazil. Key words: damselflies, aquatic insects, life cycle, taxonomy Introduction The Neotropical genus of damselflies Acanthagrion Selys, 1876 has 40 described species (Garrison & von Ellenrieder 2014), and its distribution ranges from south-central United States (Texas) to central Argentina.
