Full textDragonflies (Odonata) are one of the ancestral groups of extant insects. They represent one of the three most basal branches in the phylogeny of winged insects. The other two groups are the Ephemeroptera, mayflies, and Neoptera, the latter which covers the remaining winged insects. The first paper is about the phylogenetic position of Odonata in relation to the other basal insect clades using 18S and 28S rDNA sequences. It was demonstrated that there are under certain parameters a strong statistical support for a sister-group relationship between Odonata and Neoptera forming the group Palaeoptera. The second paper is about the phylogeny of the Holarctic dragonfly Leucorrhinia. Dragonfly larvae are frequently equipped with spines on the abdomen, with great variation in spinyness between species. From an analysis of sequences of ITS and 5.8S rDNA it was found that spines have been lost at least twice in Leucorrhinia, in the European L. rubicunda and again in a clade of North American species. The third paper is on the subfamily Ischnurinae (Odonata: Coenagrionidae), a group dominated by the two larger genera Ischnura and Enallagma along with several mono- or oligotypic genera. From the presented molecular study, using mitochondrial 16S rDNA and COII sequences, it is demonstrated that Ischnurinae, and Ischnura are monophyletic. Enallagma is not monophyletic, and the genus name Enallagma should be restricted to the E. cyathigerum clade. he fourth paper is a catalog of the genus Coenagrion, with full information on synonymy, type material and bibliographical data. The fifth paper is an appeal to the International Commission on Zoological Nomenclature to suppress the genus group name Agrion. The letter of appeal elucidates the priority of Agrion, and demonstrates why it has fallen out of use. A case if made for why Agrion should be placed on the list of unavailable names, and Calopteryx given full validity.

During nitrification there is an exchange of oxygen atoms between water and nitrite, causing the [delta]¹⁸O of nitrate produced by nitrification to be closer to the [delta]¹⁸O of water than expected. A series of lab and field experiments were set up in order to quantify the exchange, and then calculate the [delta]¹⁸O of nitrate with these values. The lab experiments tested the exchange in ammonia oxidation, using ammonia oxidizing bacteria, Nitrosomonas sp. C113a and Nitrococcus oceani, and nitrite oxidation using cultures of the nitrite oxidizing bacterium, Nitrosococcus mobilis. The exchange value in the ammonia oxidation experiments could not be calculated because of unexpected complications in the analysis in the [delta]¹⁸O of nitrite. Although we weren't able to obtain a confident value for the exchange we were able to find a way to correct the [delta]¹⁸O of nitrite, for blank and exchange that affects the sample [delta]¹⁸O value for nitrite measured by the mass spectrometer. The exchange in the nitrite oxidation experiment could not be measured because there was full abiotic exchange in the bottle preventing us from calculating biotic exchange. A control experiment was successful in eliminating this exchange by adjusting the pH to a value higher than 8 prior to inoculation of the media during the experiment. In a future nitrite oxidation experiment this change in experimental design would make it possible to measure the exchange during nitrite oxidation. The experiments were a good step toward developing the best way to measure microbially-catalyzed exchange, and hopefully this value can be quantified in future analysis.

Klak, Cornelia. "Systematics of psilocaulon N.E.BR. (Aizoaceae)." Master's thesis, University of Cape Town, 1997. http://hdl.handle.net/11427/17246.
Full textOn the basis of herbarium, living and pickled material the morphology and systematics of Psilocaulon N. E. Brown sensu Ihlenfeldt & Bittrich is investigated. Thirteen species (including one insufficiently known species) are recognized: P. articulatum, P. bicorne, P. coriarium, P. dimorphum, P. dinteri, P. foliosum, P. gessertianum, P. granulicaule, P. junceum, P. leptarthron, P. parviflorum, P. salicornioides, P. subnodosum. Species of Mesembryanthemum, Prenia, Brownanthus, Aspazom and Aptenia are used as outgroups in a cladistic analysis of Psilocaulon. The monophyly of Psilocaulon is demonstrated. As a result P. rapaceum Jacq. is excluded and transferred to Caulipsolon Klak gen. nov. The position of Psilocaulon and the monotypic genus Caulipsolon within the subfamily Mesembryanthemoideae is discussed. However, relationships of Psilocaulon and Caulipsolon to other genera remain obscure, since no synapomorphies were found to indicate sister relationships. More sampling among outgroups and/or a future molecular study may help to elucidate relationships among the genera of the Mesembryanthemoideae. Geographical distribution patterns for all species and the number of species per half-degree grid square are given. It is discussed how species diversity and geographical distribution in Psilocaulon contrasts with or corroborates existing ideas of centres of diversity and distribution patterns in the Mesembryanthema. Each species is described in detail. A description of the genera Psilocaulon and Caulipsolon is given and a key to the species is provided. Material examined is cited and full synonomy is given.
Tshiila, Aluwani Athalia. "Systematics of Ficinia clade (Cyperaceae)." Master's thesis, University of Cape Town, 2012. http://hdl.handle.net/11427/11667.
Full textIncludes bibliographical references.
Cyperaceae is a cosmopolitan graminoid family comprising about 110 genera and over 5500 species, represented in Southern Africa by 30 genera and over 500 species. The family is an integral part of wetland and grassland vegetations, a number of species have various local uses, and several species are notorious weeds in agriculture. The Ficinia clade includes five genera, namely Isolepis, Ficinia, Scirpoides, Dracoscirpoides and Hellmuthia. The clade has a centre of diversity in the Cape Floristic Region (CFR), where over 70% (113 species) of the species occur, with several taxa dispersed into alpine areas of Africa, and to Australasia, Europe and the Americas. This study aims to infer the phylogenetic relationships and patterns of macroevolution in Ficinia clade; to estimate the divergence dates and investigate the role of ecology the speciation of sister species of the genus Ficinia; and to revise the taxonomy of the species in the Ficinia indica complex (F. indica, F. dunensis, F. elatior, F. aff. indica R and F. aff. indica MF).

Full textA member of the Senecioneae subtribe Othonninae, Othonna L. is a genus of some 120 species mainly concentrated in the Greater Cape Floristic Region (GCFR) of South Africa, with a few species extending into southern Namibia, Angola and Zimbabwe. The South African species of Othonna were last revised by Harvey in 1865. Consequently many species, particularly in the winter rainfall-region, remain poorly understood. As a start to ultimately producing a complete revision of this priority genus, this study focussed on a group of some 26 tuberous geophytic species. The geophytic species were subdivided into two species groups: (1) the 'O. bulbosa' group with 23 spp., distinguished by a tuberous rootstock and well-developed stem with leaves cauline, and (2) the 'O. auriculifolia' group with ca. 3 spp., characterized by a rosulate habit with a short, condensed caudex.
