(2019), Data from: Dissecting biodiversity in a global hotspot: uneven dynamics of immigration and diversification within the Cape Floristic Region of South Africa, v2, Dataset, https://doi.org/10.5061/dryad.1cs77qn Abstract Aim: Fragmented distributions should show immigration and diversification dynamics consistent with the predictions of island biogeography theory. We test whether this applies to the fragmented Cape fynbos vegetation. Location: Southern Africa, Cape Floristic Region (CFR) Taxon: Angiosperms, Restionaceae (restios) Methods: We used a large occurrence dataset and environmental layers to characterize an existing regionalization and the intervals between the regions ecologically and spatially. We extended the available phylogeny for restios and inferred their historical biogeography using models implemented in BioGeoBEARS. We then measured the relative contribution of immigration and in situ speciation to the species richness of each region within the CFR. We used standard statistical methods to test Dryad Page 1 of 6 Wüest, Rafael O et al. ... doi:10.5061/dryad.1cs77qn the predictions of the island biogeography theory. Results: The area and environmental heterogeneity of the seven regions of the CFR are positively correlated with in situ speciation rate. Furthermore, more isolated areas, and areas colonized more recently, have proportionally higher immigration rates, and more central and older areas proportionally higher in situ speciation rates. Main Conclusions: The variation in immigration and diversification dynamics among the regions within the CFR is extensive and consistent with the archipelago model of island biography theory. This dynamic may contribute significantly to the diversity of the Cape flora. Such a model could be generally useful for understanding the generation and maintenance of diversity in biodiversity hotspots, and may even scale up to explain continental biodiversity. Usage Notes Restionaceae georeferenced occurrence data for the Cape Floristic Region The tab-delimited data contain 12903 georeferenced occurrence records of the Restionaceae occurring in the South African Cape Flora. The columns give the species names (column "GenusSpecies"; with the binary scientific names separated by underscore), the date of collection (column "Date"), the coordinates in WGS84 geographic projection (EPSG:4326; columns "Longitude" and "Latitude"), the locality (column "Locality"). Further, we indicate whether the data represents a single occurrence ("specimen") or is part of a plot-releve ("plot"; indicated in column "RecordType"). In the latter case, we indicate the plot-id in the column "PlotID". In case of specimen-data, we indicate the collector (column "Collector") and collection number ("CollectorNumber"). Where available, we also indicate simple site- characteristics in terms of rockiness (column "Rockyness"; three levels "none", "pebblesboulders", "bedrock"), soil-type (column "SoilType"; three levels "organic", "fine", "coarse"), drainage (column "Drainage"; three levels "dry", "damp", "wet"), and aspect (column "Aspect"; with "level" for flat sites and all possible combinations of "n" for North, "e" for East, "s" for South, "w" for West). restio_georef_data.txt Geology of the Cape Floristic Region The zip-archive contains a shapefile in WGS84 geographic projection (EPSG:4326) that holds (in the column "geology") spatially explicit information on six major geological classes ("calcrete", "granite", "recent sand", "silcrete", "sandstones", "shale", and "others" including water-bodies). The column "UQ_GEOL" contains the original geological class according to the South African Council for Geoscience, and "geol_num" is a numerical representation of the classes coded in column "geology". cape_geology.zip Dryad Page 2 of 6 Wüest, Rafael O et al. ... doi:10.5061/dryad.1cs77qn Environment of the Cape Floristic Region The environmental data used in this study, provided as geo-tiffs.

  • 1 March 27 a Few Days Ago, While Finding Refuge Indoors
    1 March 27 A few days ago, while finding refuge indoors from the strong wind (mainly due to the dust factor), I was quite amazed how the dynamics of the landscape seem to change with wind. Although the wind was predominately from the west, the trees and other plants would sway in all directions. They would bend to the east, straighten up and then without hesitation sway to the south and then to the north! Confusing to try and determine the actual directional source but be that as it may there was another exciting element to it all. It was the graceful dance of continuity that had no formality or predetermined steps. I so enjoy seasonal changes as each one brings something different which is a requirement of our natural world. Changes in light and temperature wake some plants up while others take a break or just go to sleep. I often think wind is an overlooked characteristic of seasonal change and for many it is just another windy day resulting in irritation and inconvenience. We can’t live without it as it is responsible for rain, spreading fire, moving soils, seed, pollen, insects, bird migration and disease. It is the power behind land, sea and air travel and the smallest of gusts can take your hat off. Like so much of the natural world we cannot control it…thankfully. Movement brings life to the garden physically and through colour as leaves flutter and show the variation between top and underside. Unfortunately, this wonderful phenomenon, is rather lost in formal gardens due to the stiffness of man made lines and unnatural shapes.

Hertweck A candidate for the degree of Doctor of Philosophy And hereby certify that, in their opinion, it is worthy of acceptance. Dr. J. Chris Pires Dr. Lori Eggert Dr. Candace Galen Dr. Rose‐Marie Muzika ACKNOWLEDGEMENTS I am indebted to many people for their assistance during the course of my graduate education. I would not have derived such a keen understanding of the learning process without the tutelage of Dr. Sandi Abell. Members of the Pires lab provided prolific support in improving lab techniques, computational analysis, greenhouse maintenance, and writing support. Team Monocot, including Dr. Mike Kinney, Dr. Roxi Steele, and Erica Wheeler were particularly helpful, but other lab members working on Brassicaceae (Dr. Zhiyong Xiong, Dr. Maqsood Rehman, Pat Edger, Tatiana Arias, Dustin Mayfield) all provided vital support as well. I am also grateful for the support of a high school student, Cady Anderson, and an undergraduate, Tori Docktor, for their assistance in laboratory procedures. Many people, scientist and otherwise, helped with field collections: Dr. Travis Columbus, Hester Bell, Doug and Judy McGoon, Julie Ketner, Katy Klymus, and William Alexander. Many thanks to Barb Sonderman for taking care of my greenhouse collection of many odd plants brought back from the field.

Published by the University of Cape Town (UCT) in terms of the non-exclusive license granted to UCT by the author. University of Cape Town Abstract Rhodocoma gigantea and Rhodocoma foliosus have been recognised by earlier authors as separate species on the basis of perianth length and shape. Linder (1985) .s perficially lumped these two species under Rhodocoma gigantea arguing that the difference between the two appear to be brought by ecological gradient. Numerical phenetic analyses of 19 quantitative floral morphological characters investigated from 33 herbarium specimens reveal that Rhodocoma gigantea complex consists of two groups. One group correspon(Jo Rhodocoma gigantea, having longer and wider spikelets, perianth segments and bracts, while the other correspond to Rhodocoma foliosus having shorter and thinner female spikelets, bracts and perianth segments than the former. Minimum spanning tree also reveal the two groups are geographically isolated. The former group occur in the western part of the south coast along the Langeberg in Swellendam and Riversdale districts and the latter is widely distributed on the Outeniekwaberg, Tsitsikama mountains to Zuurberg with outliers reaching as far as Uitenhage. 8ritz river appears to be the geographical barrier between these two species.

  • Vicariance, Climate Change, Anatomy and Phylogeny of Restionaceae
    Botanical Journal of the Linnean Society (2000), 134: 159–177. With 12 figures doi:10.1006/bojl.2000.0368, available online at http://www.idealibrary.com on Under the microscope: plant anatomy and systematics. Edited by P. J. Rudall and P. Gasson Vicariance, climate change, anatomy and phylogeny of Restionaceae H. P. LINDER FLS Bolus Herbarium, University of Cape Town, Rondebosch 7701, South Africa Cutler suggested almost 30 years ago that there was convergent evolution between African and Australian Restionaceae in the distinctive culm anatomical features of Restionaceae. This was based on his interpretation of the homologies of the anatomical features, and these are here tested against a ‘supertree’ phylogeny, based on three separate phylogenies. The first is based on morphology and includes all genera; the other two are based on molecular sequences from the chloroplast genome; one covers the African genera, and the other the Australian genera. This analysis corroborates Cutler’s interpretation of convergent evolution between African and Australian Restionaceae. However, it indicates that for the Australian genera, the evolutionary pathway of the culm anatomy is much more complex than originally thought. In the most likely scenario, the ancestral Restionaceae have protective cells derived from the chlorenchyma. These persist in African Restionaceae, but are soon lost in Australian Restionaceae. Pillar cells and sclerenchyma ribs evolve early in the diversification of Australian Restionaceae, but are secondarily lost numerous times. In some of the reduction cases, the result is a very simple culm anatomy, which Cutler had interpreted as a primitively simple culm type, while in other cases it appears as if the functions of the ribs and pillars may have been taken over by a new structure, protective cells developed from epidermal, rather than chlorenchyma, cells.

The eradication and control of invasive alien plants (IAP) is essential for the restoration of native plant communities. Understanding ecological impacts and potential invasive risks of IAP is important for their effective management, particularly for prioritisation. Most studies concerning impacts on vegetation structure and plant-pollinator interactions have measured few ecological metrics, resulting in a superficial understanding of plant species invasion.
