MoSyD-Jahresbericht 2012 : Drogentrends in Frankfurt am Main : Monitoring-System Drogentrends
(2013)
Hauptziel der Untersuchung war die Erhebung von Daten zur Verbreitung von S. arcti-cain den 17 ausgewählten Moorgebieten entlang der polnischen Ostseeküste und in der Pommerschen Seenplatte. Im Rahmen dieser Studie in odonatologisch bisher wenig bearbeiteten Gebieten wurden drei neue Fundorte von S.arctica gefunden, in denen diese Art kleine, aber beständige Populationen bildet. Zwei dieser Gebiete liegen weit von den bisher bekannten Vorkommen entfernt. Für zukünftige Arbeiten ist es wichtig zu untersuchen, ob diese Fundorte populationsökologisch isoliert sind oder ob S. arctica auch in den geographisch dazwischen liegenden Biotopen vorkommt. Ein weiteres Ziel des Vorhabens war eine Verbesserung des allgemeinen Wissens zur regionalen Libellenverbreitung. Die Studie dokumentiert für diese odonatologisch bisher nicht bearbeiteten Gebiete eine hohe Libellendiversität. Hinzu kommt, dass in 15der 17 untersuchten Gebiete mindestens eine rechtlich geschützte Libellenart vorkommt. Dies lässt vermuten, dass die Renaturierungsmaßnahmen eine positive Auswirkung für die seltenen und lebensraumspezialisierten Libellenarten haben. Diese Studie stellt somit eine Grundlage für zukünftige Analysen zur Bewertung des Erfolges der aktiven Moorschutzmaßnahmen auf Basis der Libellen dar.
A two week trip to Costa Rica was conducted between 26 May and 8 June 2013, sampling odonates in several provinces along the center to the pacific southern portionof the country. A total of 86 species in 34 genera were found, including 16 species of the genus Argia. Lists of all species by locality, photographs of live specimens, and illustrations and notes of described species of Argiaare presented to facilitate identification to other collectors.
Odonata survey was conducted in Talaingod, Davao del Norte, Mindanao Island. Four major sites were explored in Barangay Santo Niño from December 26 – 30, 2012. Thirty five species under eleven families including one new species were found representing the first odonatological record in the province of Davao del Norte. Three species need further study while Orthetrum glaucum represents a new record for the island of Mindanao. Coeliccia exoleta population, a vulnerable species in the IUCN Red List of Threatened Species, was found.
The Odonata fauna of Balabac Island, Philippines was studied in March 2013. A total of 41 species under 33 genera were recorded. Twenty-eight species were recorded for the first time in the island. One genus – Mortonagrion was recorded for the first time in the Philippines. Mortonagrion astamii spec. nov. and Prodasineura poncei spec. nov. are new to science and are described. Three previously recorded species remained elusive and not seen during the survey.
Dragonflies from mainland Yemen and the Socotra Archipelago : additional records and novelties
(2013)
The odonatological results of two field trips to mainland Yemen carried out mainly in summer 2005 and winter 2007, and to Socotra in winter 1999 are put on record. At 30 localities, 33 dragonfly species were collected, respectively observed. One species,Azuragrion somalicum, is new for mainland Yemen, and a second, Pseudagrion niloticum, is new for mainland Yemen and the Arabian Peninsula. Three species, Azuragrionsomalicum, Orthetrum julia, and Sympetrum fonscolombiiare new records for Socotra.
A survey of Odonata in North Ethiopia, on the route Debre Libanos – Bahir Dar – Woldia – Hayk – Mile – Awash – Debre Zeyit crossing the provinces of Oromia, Amhara and Afar, in July 29 - August 10, 2012 yielded 38 species, including two endemics of Ethiopia and five species not hitherto reliably reported for this country in the literature: Pseudagrion commoniae (Forster, 1902), P. hamoni Fraser, 1955, P. salisburyense Ris, 1921, Bradinopyga strachani (Kirby, 1900) and Ictinogomphus ferox (Rambur, 1842). The number of Odonata species recorded in Ethiopia thus reached 104. Seventeen main localities were visited, on average showing 4.9 species per locality. A small branch of Jara River, Amhara, was the richest one (15 species). Comments on specimens of Pseudagrion spernatum Selys, 1881 and Nesciothemis farinosa (Forster, 1898) and notes on the country in general and particular habitats of Odonata are provided.
