Endemic Plants of St. Helena: Potential for Rescue, Inherent Variation Within Species, and the Future of Babies’ Toes and the Lowland Desert Habitat Endemic Plants of St. Helena: Potential for Rescue, Inherent Variation within Species, and the Future of Babies’ Toes and the Lowland Desert Habitat https://sthelenaisland.info/flora/scrubwood/ Melissa Starkey August 2020 Thesis submitted in partial fulfillment of the MSc in the Biodiversity and Taxonomy of Plants. Acknowledgements Special thanks to my supervisor, Dr. Alan Gray, for his guidance, support, expertise, and good discussions. His enthusiasm about St. Helena was contagious from the start. Thanks also to my co-supervisor, Dr. Greg Kenicer for helpful comments and feedback on my project. I am indebted to Gerrie, Scott, and Kay, for their unwavering support both at home and from afar. i Abstract St. Helena is a remote volcanic island in the South Atlantic Ocean with a diverse topology and a rich endemic flora. Due to anthropogenic factors, many plant species have been reduced to small, severely fragmented populations, resulting in genetic erosion and a more limited ability to adapt to environmental pressures. This thesis addresses conservation of St. Helena’s endemic flora relating to themes of genetic variation and climate change. Chapter one introduces the island and its flora. Chapter two reviews the literature on genetic rescue in plants and shows that it can be beneficial for small, fragmented populations, though additional research is needed. Chapter three conceptually applies the genetic rescue approach to St. Helena’s critically endangered endemic plants, many of which are promising candidates for the strategy and are predicted to be heading rapidly towards extinction. Chapter four assesses historical levels of variation through morphometric analysis using herbarium specimens of three endemic St. Helena genera: Carex L., Phylica L., and Wahlenbergia Schrad. ex Roth; proposes areas for further research and conservation, and addresses taxonomic issues for Carex. Chapter five discusses potential impacts from climate change and increased tourism in St. Helena’s lowland desert habitat and proposes conservation actions and future research directions. Chapter six provides a brief conclusion to the thesis, which will contribute valuable insights for informing conservation decisions on St. Helena. ii Table of Contents Acknowledgements ......................................................................................................................................................... i Abstract ................................................................................................................................................................................. ii Chapter 1: Introduction and Aims .......................................................................................................................... 1 The Island of Saint Helena ......................................................................................................................................... 1 The Flora of Saint Helena ........................................................................................................................................... 2 Extinction of and Threats to St. Helena’s Flora ................................................................................................. 4 Conservation Efforts on St. Helena ......................................................................................................................... 7 Thesis Aims ...................................................................................................................................................................... 8 Chapter 2: Genetic Rescue as a Conservation Strategy ............................................................................. 9 Introduction ..................................................................................................................................................................... 9 Genetic Rescue: One Potential Solution ............................................................................................................ 10 What Can Go Wrong?

We conducted an experiment using potted seedlings grown without shade, or under low, KEY WORDS moderate, or heavy shade enclosures. Shade did not affect revegetation, coastal strand, propagation, light shoot growth, or leaf or stem dry mass. Plants subjected to all levels of shade, however, had 40% to 70% less root dry NOMENCLATURE mass and about 50% lower root-to-shoot ratios than non- ITIS (2002) shaded plants.

  • Vestured Pits in Wood of Onagraceae: Correlations with Ecology, Habit, and Phylogeny1
    VESTURED PITS IN WOOD OF Sherwin Carlquist2 and Peter H. Raven3 ONAGRACEAE: CORRELATIONS WITH ECOLOGY, HABIT, AND PHYLOGENY1 ABSTRACT All Onagraceae for which data are available have vestured pits on vessel-to-vessel pit pairs. Vestures may also be present in some species on the vessel side of vessel-to-ray pit pairs. Herbaceous Onagraceae do not have fewer vestures, although woods with lower density (Circaea L. and Oenothera L.) have fewer vestures. Some Onagraceae from drier areas tend to have smaller vessel pits, and on that account may have fewer vestures (Epilobium L. and Megacorax S. Gonz´alez & W. L. Wagner). Pit apertures as seen on the lumen side of vessel walls are elliptical, occasionally oval, throughout the family. Vestures are predominantly attached to pit aperture margins. As seen from the outer surfaces of vessels, vestures may extend across the pit cavities. Vestures are usually absent or smaller on the distal portions of pit borders (except for Ludwigia L., which grows consistently in wet areas). Distinctive vesture patterns were observed in the several species of Lopezia Cav. and in Xylonagra Donn. Sm. & Rose. Vestures spread onto the lumen-facing vessel walls of Ludwigia octovalvis (Jacq.) P. H. Raven. Although the genera are presented here in the sequence of a recent molecular phylogeny of Onagraceae, ecology and growth forms are more important than evolutionary relationships with respect to abundance, degree of grouping, and morphology of vestured pits. Designation of vesture types is not warranted based on the distribution of named types in Onagraceae and descriptive adjectives seem more useful, although more data on vesturing in the family are needed before patterns of diversity and their extent can be fully ascertained.
