Critical Species of Odonata in Eastern Africa
--- Guardians of the watershed. Global status of dragonflies: critical species, threat and conservation --- Critical species of Odonata in eastern Africa Viola Clausnitzer Liebenauer Stra~e 180, D-0611 0 Halle/Saale, Germany. <violacl®gmx.de> Key words: Odonata, dragonfly, IUCN, critical species, conservation, eastern Africa. ABSTRACT From eastern Africa, ranging from Somalia and Ethiopia south to Mozambique and Zimbabwe and west to eastern Democratic Republic of Congo and Botswana, ca 500 species of Odonata are known. Comments on species and sites of conserva tion concern are given as well as recommendations for future research and conservation activities. Due to the rapid and ongoing destruction of forests, especially of coastal, Guineo-Congolian and Eastern Arc forests, species confined to these habitats are the most threatened. REGIONAL DEFINITION Eastern Africa is not a fixed political or geographical description for a specific area. Here the term is used for the region comprising the Rift Valley from Ethiopia south ward to Mozambique and northern Botswana and westward to eastern Democratic Republic of Congo and eastern Angola. The neighbouring regions are covered to the south by Sam ways (2004 ), to the southwest by Suhling et al. (2004 ), to the west by Dijkstra & Vick (2004) and to the north by Jodicke et al. (2004). As biogeo graphy and faunistic distributions do not follow political borders, there may be overlaps with neighbouring regions. The area considered here covers some of the most important centres for endemism and regions of high biodiversity in Africa, namely forested mountain chains along the Albertine Rift and the Eastern Arc and coastal forests (e.g. -
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. -
Description of the Final Stadium Larva of Erythrodiplax Media (Odonata
International Journal of Odonatology, 2018 Vol. 21, No. 2, 93–104, https://doi.org/10.1080/13887890.2018.1462260 Description of the final stadium larva of Erythrodiplax media (Odonata: Libellulidae) with preliminary key to known South American larvae in the genus Marina Schmidt Dalzochio a∗, Eduardo Périco a, Samuel Renner a and Göran Sahlén b aLaboratório de Ecologia e Evolução, Universidade do Vale do Taquari – UNIVATES, Lajeado, RS, Brazil; bEcology and Environmental Science, The Rydberg Laboratory for Applied Sciences (RLAS), Halmstad University, Halmstad, Sweden (Received 25 July 2017; final version received 6 March 2018) The larva of Erythrodiplax media is described and illustrated based on two exuviae of reared larvae and one final stadium larva collected in Xangri-lá, State of Rio Grande do Sul, Brazil. The larva of E. media can be distinguished from other species of Erythrodiplax by the presence of lateral spines on S8 and S9, the number of premental setae (n = 22), palpal setae (n = 7) and by the mandibular formula. We also provide a preliminary key to known South American larvae in the genus. Keywords: Brazil; coastal wetlands; dragonfly; exuvia; Anisoptera Introduction Erythrodiplax Brauer, 1868 is an American genus that includes 60 species (Schorr & Paulson, 2017), of which 40 are known to occur in Brazil (Pinto, 2017) and 18 are hitherto reported from the state of Rio Grande do Sul (Consatti, Santos, Renner & Périco, 2014;Costa,1971; Hanauer, Renner & Périco, 2014; Kittel & Engels, 2016; Renner, Périco & Sahlén, 2013, 2016; Renner, Périco, Sahlén, Santos & Consatti, 2015; Teixeira, 1971). The genus consists of many rather similar species, which makes diagnosis difficult. -

Annual Report 2012 English
Annual Report 2012 Annual Report 2012 The Mohamed bin Zayed Species Conservation Fund provides financial support to species conservation projects worldwide. In 2012, The Mohamed bin Zayed Species Conservation Fund supported 217 projects in 75 countries with more than $1.5m. More than $1.36m was granted to species listed as Critically Endangered, Endangered, or Vulnerable by the IUCN Red List. Your Highness In 2012 the Fund has been able to greatly aid the global effort to conserve the diversity of life by continuing its success and giving $1.5m to more than 200 projects worldwide. Since its inception, the Fund has now disbursed more than $8.7m to targeted species conservation work, implemented through nearly 825 projects in more than 125 countries across six continents. The impact of the Fund continues to amaze me. Among the more than 200 projects supported in 2012, the financial support provided by the Fund helped train a pilot in Kenya who is now patrolling rhino habitat for poachers; it helped locate the breeding grounds of a sea bird previously thought to be extinct; it aided in the discovery of several new tree species in Mexico and many new species of spiders in India; it protected the habitat of a butterfly in Nepal and that of a cave-dwelling amphibian in Croatia. The stories of success are replicated across many species, in many locations across the globe. In 2012, the Fund received more than 1,500 grant applications – a statistic clearly indicating the global urgency of species conservation and the popularity of the Fund. -

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. -
