LLOYD2,3,JUAN MANUEL PERILLALÓPEZ4, VANESSA L. GONZÁLEZ2, ARIANNA THOMAS-CABIANCA5 andTORSTEN DIKOW2 1Museum für Naturkunde, Leibniz Institute for Evolution and Biodiversity Science, Berlin, Germany, 2National Museum of Natural History, Smithsonian Institution, Washington, DC, U.S.A., 3The Jackson Laboratory, Bar Harbor, ME, U.S.A., 4Department of Biological Sciences, Wright State University, Dayton, OH, U.S.A. and 5Department of Environmental Science and Natural Resources, University of Alicante, Alicante, Spain Abstract. The diverse superfamily Oestroidea with more than 15 000 known species includes among others blow flies, flesh flies, bot flies and the diverse tachinid flies. Oestroidea exhibit strikingly divergent morphological and ecological traits, but even with a variety of data sources and inferences there is no consensus on the relationships among major Oestroidea lineages. Phylogenomic inferences derived from targeted enrichment of ultraconserved elements or UCEs have emerged as a promising method for resolving difficult phylogenetic problems at varying timescales. To reconstruct phylogenetic relationships among families of Oestroidea, we obtained UCE loci exclusively derived from the transcribed portion of the genome, making them suitable for larger and more integrative phylogenomic studies using other genomic and transcriptomic resources. We analysed datasets containing 37–2077 UCE loci from 98 representatives of all oestroid families (except Ulurumyiidae and Mystacinobiidae) and seven calyptrate outgroups, with a total concatenated aligned length between 10 and 550 Mb. About 35% of the sampled taxa consisted of museum specimens (2–92 years old), of which 85% resulted in successful UCE enrichment.

This review is a compilation of the currently known occur- rence of blow fly species in Thailand, the fly’s medical importance and its morphological identification in all stages. So far, the 93 blow fly species identified belong to 9 subfamilies, including Subfamily Ameniinae, Calliphoridae, Luciliinae, Phumosiinae, Polleniinae, Bengaliinae, Auchmeromyiinae, Chrysomyinae and Rhiniinae. There are nine species including Chrysomya megacephala, Chrysomya chani, Chrysomya pinguis, Chrysomya bezziana, Achoetandrus rufifacies, Achoetandrus villeneuvi, Ceylonomyia nigripes, Hemipyrellia ligurriens and Lucilia cuprina, which have been documented already as medically important species in Thailand. According to all cited reports, C. megacephala is the most abundant species. Documents related to morphological identification of all stages of important blow fly species and their medical importance also are summarized, based upon reports from only Thailand.

  • Oecophylla Longinoda, an Ant Predator of Anomma Driver Ants (Hymenoptera Formicidae)* by William H
    OECOPHYLLA LONGINODA, AN ANT PREDATOR OF ANOMMA DRIVER ANTS (HYMENOPTERA FORMICIDAE)* BY WILLIAM H. COTWALD, JR. Department o Biology, Utica College o Syracuse University Utica., New York, I35O2 Ants o the subgenus A nomma, one ot 6 subgenera composing the genus Dorylus, are commonly reerred to as "driver ants." The driver ant receives its name appa.rently because it "drives everything before it capable o muscular movement, so ormidable is it rom its numbers and bite ." (Savage, 847). O the Dorylus subgenera, Anomma is most conspicuous. Its species are aggressive, primarily epigaeic oragers (i.e. surface adapted as opposed to subterranean) with colo.nies consisting ot up to 22 million individuals (Raignier and van Boven, 955). Although the erocity ot the Anomma driver ants has been fictionalized and tales o their behavior are in- corporated into Arican olklo.re, their pugnacity has been repeatedly documented (Loveridge, 922 Raignier and van Boven, 9.55 Savage, 847, 849; Wheeler 9o, 922). The driver ants have also been described as clearly dominant animals (Weber, 943). Without a doubt, they appea.r as efficient predato,rs, having evolved a system o group predation o significant adaptive advantage in trop- ical environments. However, these carnivores are themselves no.t without predators. Bequaert (922) reports Anomma species rom the stomachs ot 4 species o.x Arican toa.ds (genus Bufo) and 3 species, ot Arican rogs (in the genera Rana, Kassina, Hemisus). He also reports that driver ants are commonly eaten by Arican skinks o the genus Mabuya and by pangolins (scaly anteaters) o the genus Manis.

  • Pollination and Germination As Limiting Factors in the Propagation of Threatened Cycads, Encephalartos (Zamiaceae)
    Pollination and germination as limiting factors in the propagation of threatened cycads, Encephalartos (Zamiaceae) Phakamani M’Afrika Xaba A thesis submitted in partial fulfilment of the requirements for the degree of Magister Scientiae in the department of Biodiversity and Conservation Biology of the University of Western Cape. Date of submission: 12 November 2014 KEY WORDS Encephalartos latifrons Encephalartos altensteinii Pollen viability Pollen storage Pollen germination Artificial wet pollination Artificial dry pollination Seed storage Seed pre-treatment Seed germination i ABSTRACT Cycads are the most threatened living organisms assessed to date (IUCN, 2010). Encephalartos is an African cycad genus which in South Africa has a high diversity but threatened status. This study focuses on the Critically Endangered cycad Encephalartos latifrons, which exhibits low seed viability (< 10) in ex situ living collections in the Kirstenbosch National Botanical Garden (KNBG). This is the largest known ex situ collection of E. latifrons, and the conservation programme of this species has been negatively affected by the unknown cause of low seed germination. This study hypothesised that low seed germination in E. latifrons at KNBG was caused by: firstly, low pollen viability as a result of storage or environmental conditions; secondly by factors with the wet artificial pollination method and its synchronous application to the diurnal formation of pollination droplets in ovules; thirdly, seed storage factors (period and environmental conditions) and the lack of seed pre-treatment (scarification and hormone). This study compared E. latifrons to a more common cycad E. altensteinii with high seed viability (> 60%) at KNBG. Encephalartos latifrons pollen viability results show that fresh and stored pollen of specimens cultivated at KNBG was high (>60%) and comparable to pollen from the wild, that was above the recommended standard (>40%) (Stanley & Linskens, 1974), and only started losing viability after three years.

(Signed) BOMO EDITH EDNA MOLEWA MINISTER OF WATER AND ENVIRONMENTAL AFFAIRS Page 1 of 46 SCHEDULE BIODIVERSITY MANAGEMENT PLAN FOR ENCEPHALARTOS LATIFRONS environmental affairs Department: Environmental Affairs REPUBLIC OF SOUOTH AFRICA Page 2 of 46 EXECUTIVE SUMMARY Cycads are special botanical features in South Africa's rich biodiversity. They are naturally rare, relatively slow growing, attain very old age and are structurally very appealing. Many of the species that occur in southern Africa are local endemics and their reproductive ecology, i.e. the need for coning synchronicity and the presence of pollen and seed vectors within their habitat, exacerbates this naturally rare status. In addition to this they have also attracted the attention of avid collectors and traders who are not satisfied with obtaining seedlings from breeding programmes, but who prefer the immediate gratification of being able to obtain mature specimens. Due to their slow growth rates, these then tend to be removed from natural populations within their natural distribution range to satisfy this demand.
