  • 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-mail: [email protected] Abstract Syncordulia (Odonata: Anisoptera: Libelluloidea) inhabits mostly cool mountainous streams in the Cape Floristic Region of South Africa. It is found at low densities in geographically restricted areas. Syncordulia is endemic to South Africa and, until recently, only two species were known, S. venator (Barnard, 1933) and S. gracilis (Burmeister 1839), both considered Vulnerable by the World Conservation Union (IUCN). Two new species, S. serendipator Dijsktra, Samways & Simaika 2007 and S. legator Dijsktra, Samways & Simaika 2007, were described from previously unrecognized museum specimens and new field collections. Here we corroborate the validity of these two new species using multiple genes and propose intergeneric relationships within Syncordulia. Molecular data from two independent gene fragments (nuclear 28S and ribosomal and cytochrome oxidase subunit I mitochondrial data) were sequenced and/or downloaded from GenBank for 7 libelluloid families, including 12 Syncordulia specimens (2 Syncordulia gracilis, 4 S. serendipator, 2 S. legator and 4 S. venator). The lower libelluloid group GSI (sensu Ware et al. 2007), a diverse group of non– corduliine taxa, is strongly supported as monophyletic.

  • A Review of the Impacts and Opportunities for African Urban Dragonflies
    insects Review A Review of the Impacts and Opportunities for African Urban Dragonflies Charl Deacon * and Michael J. Samways Department of Conservation Ecology and Entomology, Stellenbosch University, Matieland, Stellenbosch 7600, South Africa; [email protected] * Correspondence: [email protected] Simple Summary: The expansion of urban areas in combination with climate change places great pressure on species found in freshwater habitats. Dragonflies are iconic freshwater organisms due to their large body sizes and striking coloration. They have been widely used to indicate the impacts of natural and human-mediated activities on freshwater communities, while also indicating the mitigation measures required to ensure their conservation. Here, we review the major threats to dragonflies in southern Africa, specifically those in urban areas. We also provide information on effective mitigation measures to protect dragonflies and other aquatic insects in urban spaces. Using three densely populated areas as case studies, we highlight some of the greatest challenges for dragonflies in South Africa. More importantly, we give a summary of current mitigation measures which have maintained dragonflies in urban spaces. In addition to these mitigation measures, public involvement and raising awareness contribute greatly to the common cause of protecting dragonflies around us.

    Copyedited by: OUP Insect Systematics and Diversity, 1(1), 2017, 73–80 doi: 10.1093/isd/ixx005 Paleontology Research Relevant Relicts: The Impact of Fossil Distributions on Biogeographic Reconstruction Phillip Barden,1,3 and Jessica L. Ware2 1New Jersey Institute of Technology, Newark, NJ, 2Rutgers, The State University of New Jersey, Newark, NJ, and 3Corresponding author, e-mail: [email protected] Subject Editor: James Whitfield Received 16 May 2017; Editorial decision 9 September 2017 Abstract Localized extinction can play a significant role in obscuring reconstructions of historical biogeography. Insects, one of the most diverse clades in the tree of life, have complex patterns of local endemism, patterns of relictual distributions, and clades which are rather widespread and cosmopolitan. At the same time, insects have a rich fossil record that can contribute to the inference of ancestral geographical distributions, in light of present ranges. Here, we review current and ancestral insect distributions to explore the impact of fossil ranges on ancestral area reconstruction. Known examples of relictual distributions within Phasmatodea and termites are discussed, while we test the impact of fossil inclusion on biogeographic reconstruction within ants and dragonflies. The inclusion of fossil distributions increases the breadth of ancestral ranges across several nodes in ant and dragonfly phylogenies, which has implications for biogeographically based interpretations of past evolutionary ecology for these groups. More broadly, the incorporation of fossil data into estimates of ancestral distributions will not only improve the accuracy of those estimates but also provide additional temporal context. Key words: biogeography, dragonfly, fossil, termite, ant Present-day distributions of organisms are the direct consequence biogeographic history of organisms remains unclear given available of past instances of dispersal, vicariance, and extinction (Wiens and methodology.

Ninety-three ingroup taxa and six outgroup taxa were amplified for the 28S fragment; 78 ingroup taxa and five outgroup taxa were amplified for the 16S fragment.
