The Reproductive Biology, Natural Enemies and Biological Control of Delairea Odorata Lem
The Reproductive Biology, Natural Enemies and Biological Control of Delairea odorata Lem. by Carol Ann Rolando Submitted in fulfilment of the requirements for the degree of Master of Science in the School of Botany and Zoology, University of Natal, Pietermaritzburg, March 2000 ABSTRACT Delairea odorata Lem., an asteraceous perennial vine indigenous to southern Africa, has become naturalised and invasive in many subtropical regions including California, South Australia and Hawaii. Biological control offers a potential long term solution to the management of this species in exotic locations. This study analysed aspects ofthe biology ofD. odorata in its native environment to determine its suitability to classical biological control. To this end an examination of the reproductive biology and natural enemies of D. odorata was made. A study of the pyrrolizidine alkaloid profile was also conducted. Reproductive biology: Delairea odorata reproduces both sexually by seeds and asexually by stolons. The flowering season occurs over the autumn months from April to June. Results ofthe pollination trials indicate thatD. odorata is a cross compatible species and an obligate outbreeder. There is no specialised pollination system and the predorninant pollinators belong to the families Apidae, Syrphidae and Calliphoridae. Following pollination, numerous small achenes are produced. Laboratory trials indicate that these achenes germinate readily between 10 and 25 QC and, although germination occurs in both the light and dark, light clearly stimulates seed germination. Greenhouse trials conducted to determine the effect of light on growth and reproduction indicate that D. odorata is a shade tolerant species which shows plasticity in terms ofgrowth form and deployment ofbiomass in response to changes in light intensity. -
The Radiation of Satyrini Butterflies (Nymphalidae: Satyrinae): A
Zoological Journal of the Linnean Society, 2011, 161, 64–87. With 8 figures The radiation of Satyrini butterflies (Nymphalidae: Satyrinae): a challenge for phylogenetic methods CARLOS PEÑA1,2*, SÖREN NYLIN1 and NIKLAS WAHLBERG1,3 1Department of Zoology, Stockholm University, 106 91 Stockholm, Sweden 2Museo de Historia Natural, Universidad Nacional Mayor de San Marcos, Av. Arenales 1256, Apartado 14-0434, Lima-14, Peru 3Laboratory of Genetics, Department of Biology, University of Turku, 20014 Turku, Finland Received 24 February 2009; accepted for publication 1 September 2009 We have inferred the most comprehensive phylogenetic hypothesis to date of butterflies in the tribe Satyrini. In order to obtain a hypothesis of relationships, we used maximum parsimony and model-based methods with 4435 bp of DNA sequences from mitochondrial and nuclear genes for 179 taxa (130 genera and eight out-groups). We estimated dates of origin and diversification for major clades, and performed a biogeographic analysis using a dispersal–vicariance framework, in order to infer a scenario of the biogeographical history of the group. We found long-branch taxa that affected the accuracy of all three methods. Moreover, different methods produced incongruent phylogenies. We found that Satyrini appeared around 42 Mya in either the Neotropical or the Eastern Palaearctic, Oriental, and/or Indo-Australian regions, and underwent a quick radiation between 32 and 24 Mya, during which time most of its component subtribes originated. Several factors might have been important for the diversification of Satyrini: the ability to feed on grasses; early habitat shift into open, non-forest habitats; and geographic bridges, which permitted dispersal over marine barriers, enabling the geographic expansions of ancestors to new environ- ments that provided opportunities for geographic differentiation, and diversification. -
Do Butterflies Use “Hearing Aids”? Investigating the Structure and Function of Inflated Wing Veins in Nymphalidae
Do butterflies use “hearing aids”? Investigating the structure and function of inflated wing veins in Nymphalidae by Penghui (Carrie) Sun A thesis submitted to the Faculty of Graduate and Postdoctoral Affairs in partial fulfillment of the requirements for the degree of Master of Biology in Biology Carleton University Ottawa, Ontario © 2018 Penghui (Carrie) Sun Abstract Many butterfly species within the subfamily Satyrinae (Nymphalidae) have been informally reported to possess a conspicuous “inflated” or “swollen” subcostal vein on each forewing. However, the function and taxonomic diversity of these structures is unknown. This thesis comprises both experimental and comparative approaches to test hypotheses on the function and evolution of these inflated veins. A laser vibrometry study showed that ears in the common wood nymph, Cercyonis pegala, are tuned to sounds between 1-5 kHz and the inflated subcostal vein enhances sensitivity to these sounds. A comparative study showed that all species with inflated veins possess ears, but not all species with ears possess inflated veins. Further, inflated veins were better developed in smaller butterflies. This thesis provides the first evidence for the function of inflated wing veins in butterflies and supports the hypothesis that they function as aids to low frequency hearing. ii Acknowledgements I thank my supervisor Dr. Jayne Yack for the continued guidance and support, throughout my academic program and in beginning my career, as well as an inspired and newfound appreciation I never knew I could have for insects.

Tropical Birding Trip Report SOUTH AFRICA SEPTEMBER 2016 South Africa: Fairest Cape to Kruger 9-24 September, 2016 Barrier of Spears extension 25 September - 1 October TOUR LEADER: Charley Hesse Report and photos by Charley Hesse. All photos were taken on this tour The Fynbos endemic Orange-breasted Sunbird feeding on a Protea flower This tour gave clients a wonderful introduction to the birds, mammals and landscapes of this beautiful and varied country. The effects of a nationwide, prolonged drought were particularly evident in Kruger and Mkuze where bird numbers were down considerably. Ironically, our birding was rained out at other sites, meaning that we lost some birding time. Despite these setbacks, we still did well for birds and even had a few surprises, including the rare Mangrove Kingfisher at Umlalazi and Southern Pied Babbler north of Pretoria. We did particularly well on mammals and saw 58 species, including Cheetah, African Wildcat and Cape Porcupine. The diversity of landscapes and natural beauty of the country was an surprise to all the clients and it was certainly an unforgettable trip. www.tropicalbirding.com +1-409-515-9110 [email protected] Tropical Birding Trip Report SOUTH AFRICA SEPTEMBER 2016 9th September – Cape Town area Today was supposed to be the arrival day, but as all the participants had arrived early, it meant that we had the whole day to go birding. Everybody had arrived late last night so after breakfast at a reasonable hour, we started our birding at the world-famous Kirstenbosch Botanical Gardens. As we walked through the beautiful gardens, we quickly found many Cape specialties including: Cape Francolin, Bulbul, White-eye, Robin-Chat & Canary. -

Date: March 2021 Copyright © 2021 Stellenbosch University All rights reserved ii Stellenbosch University https://scholar.sun.ac.za Summary Wetlands are socioeconomically important, providing valuable goods and services, and supporting high levels of biodiversity, making them a top conservation priority. KwaZulu-Natal agroforestry plantations have large ecological networks of remnant land, rich in wetlands and ponds, having similar biodiversity value to protected areas. It is important that we continue to make wetlands a priority by developing efficient conservation and land management techniques. More knowledge is required to make recommendations not only to protect water sources but also freshwater biodiversity. Biological surrogates are useful in conservation planning. However, they need to be easy and cost- effective to sample, show high sensitivity to anthropogenic change, and ideally have similar assemblage patterns to other taxa. -

Eskom Holdings Limited ENVIRONMENTAL IMPACT ASSESSMENT FOR THE PROPOSED NUCLEAR POWER STATION (‘NUCLEAR-1’) AND ASSOCIATED INFRASTRUCTURE Terrestrial Invertebrate Assessment Ecocheck February 2014 EXECUTIVE SUMMARY During the two field surveys of August – September 2012 and December 2013, 605 invertebrate species were collected at the 51 sample points at Duynefontein, Bantamsklip and Thyspunt. Of the 605 species, 138 species were only found at Duynefontein, 205 species only at Bantamsklip and 166 species were only sampled at Thyspunt. Twenty-seven species were only found within the Western Strandveld area (including Duynefontein and Bantamsklip only), and 69 eurytopic species (wide geographic distribution) were sampled. The invertebrates found during the two field investigations included snails, centipedes, millipedes, amphipods, ticks, scorpions, spiders and insects. Most of the species were identified to family level; 133 species were identified to genus or species level. A Wishbone Trapdoor Spider of the genus Spiroctenus Simon, 1889 was collected at the Bantamsklip site during the December 2013 field investigation. A very good series of live specimens were sent to specialist Ian Engelbrecht, including several sub-adult males. The species is likely to be an undescribed species of Spiroctenus Simon, 1889 (it is impossible to be certain until the sub-adult males have reached maturity); the same species was misidentified during the first survey as a species of Ancylotrypa Simon, 1889 (Wafer-lid Trapdoor Spider). A species of Common Baboon Spider of the genus Harpactira Ausserer, 1871 was also collected at the Bantamsklip site. The specimen collected is designated as Harpactira cf. cafreriana (Walckenaer, 1837), the Cape Orange Baboon Spider, but positive identification is not possible until adult males of the population at Bantamsklip are collected (only a female was collected during the December 2013 field investigation). -
