The Vegetation of Whale Island. Part II. Species List of Vascular Plants, By Tane (1971) 17:39-46 39 THE VEGETATION OF WHALE ISLAND PART II. SPECIES LIST OF VASCULAR PLANTS by B.S. Parris* ABSTRACT A list of vascular plants found on Whale Island is presented together with the abundance of each species and the plant communities in which it occurs. INTRODUCTION This list was drawn up during the July visit and only a few species were added on the August visit. Further collections at more favourable seasons would probably add more species, particularly adventive annuals, to the list. The plant communities are as in Parris et al. (1971). Specimens of most species are lodged in the herbarium of the Auckland Institute and Museum. Nomenclature is as follows: indigenous dicotyledons and ferns, 'Flora of New Zealand' Vol. 1 by H.H. Allan (1961); indigenous monocotyledons, 'Flora of New Zealand' Vol. 2 by L.B. Moore and E. Edgar (1970); adventive species, 'Handbook of the Naturalised flora of New Zealand' by H.H. Allan (1941) and 'A Guide to the Identification of Weeds and Clovers' by A.J. Healy (1970).

  • The New Zealand Rain Forest: a Comparison with Tropical Rain Forest! J
    The New Zealand Rain Forest: A Comparison with Tropical Rain Forest! J. W. DAWSON2 and B. V. SNEDDON2 ABSTRACT: The structure of and growth forms and habits exhibited by the New Zealand rain forest are described and compared with those of lowland tropical rain forest. Theories relating to the frequent regeneration failure of the forest dominants are outlined. The floristic affinities of the forest type are discussed and it is suggested that two main elements can be recognized-lowland tropical and montane tropical. It is concluded that the New Zealand rain forest is comparable to lowland tropical rain forest in structure and in range of special growth forms and habits. It chiefly differs in its lower stature, fewer species, and smaller leaves. The floristic similarity between the present forest and forest floras of the Tertiary in New Zealand suggest that the former may be a floristically reduced derivative of the latter. PART 1 OF THIS PAPER describes the structure The approximate number of species of seed and growth forms of the New Zealand rain plants in these forests is 240. From north to forest as exemplified by a forest in the far north. south there is an overall decrease in number of In Part 2, theories relating to the regeneration species. At about 38°S a number of species, of the dominant trees in the New Zealand rain mostly trees and shrubs, drop out or become forest generally are reviewed briefly, and their restricted to coastal sites, but it is not until about relevance to the situation in the study forest is 42°S, in the South Island, that many of the con­ considered.

    Biodiversity Summary for NRM Regions Species List What is the summary for and where does it come from? This list has been produced by the Department of Sustainability, Environment, Water, Population and Communities (SEWPC) for the Natural Resource Management Spatial Information System. The list was produced using the AustralianAustralian Natural Natural Heritage Heritage Assessment Assessment Tool Tool (ANHAT), which analyses data from a range of plant and animal surveys and collections from across Australia to automatically generate a report for each NRM region. Data sources (Appendix 2) include national and state herbaria, museums, state governments, CSIRO, Birds Australia and a range of surveys conducted by or for DEWHA. For each family of plant and animal covered by ANHAT (Appendix 1), this document gives the number of species in the country and how many of them are found in the region. It also identifies species listed as Vulnerable, Critically Endangered, Endangered or Conservation Dependent under the EPBC Act. A biodiversity summary for this region is also available. For more information please see: www.environment.gov.au/heritage/anhat/index.html Limitations • ANHAT currently contains information on the distribution of over 30,000 Australian taxa. This includes all mammals, birds, reptiles, frogs and fish, 137 families of vascular plants (over 15,000 species) and a range of invertebrate groups. Groups notnot yet yet covered covered in inANHAT ANHAT are notnot included included in in the the list. list. • The data used come from authoritative sources, but they are not perfect.

  • PLANT of the MONTH – LITSEA CALICARIS Plant of the Month for September Is Litsea Calicaris (Mangeao, Tangeao)
    E-newsletter: No 106. September 2012 Deadline for next issue: Monday 15 October 2012 President’s message The New Zealand Plant Conservation Network will be 10 years old in April! It is hard to believe that the Network will have been in place for a decade, but so much has been achieved in that time. Around 2,000 people read this newsletter and our website use is huge. The 7,300 plant species pages, 23,000 plant images, 1.4 million plant distribution records and other website information/features provide a very valuable plant conservation resource that did not exist before the Network began. We will be celebrating this birthday with a conference, so book that May date in your diaries (see later in this newsletter). Also in this edition, are details of another major celebration (75 years this time!)— Auckland Botanical Society’s Diamond Jubilee Celebrations will feature a programme of lectures and a celebration dinner in late October (see Events for more information). This month, we have an article about a fantastic find on Banks Peninsula. Pittosporm obcordatum has been rediscovered after 170 years—well done Melissa. Two new features have been added to the website; an illustrated glossary and species pages of all of New Zealand’s marine algae, so check them out. We are calling for nominations for the NZPCN Plant Conservation Awards. I’m sure that you know of a person, group, council, school or nursery that you could nominate for the great work they are doing for plant conservation. Finally, look out for our AGM invitation in the next newsletter.

Introduction Rushes (family Juncaceae) are a common component of New Zealand wetland vegetation and species within this family appear very similar. With over 50 species, Juncus are the largest component of the New Zealand rushes and are notoriously difficult for amateurs and professionals alike to identify to species level. This key and accompanying factsheets have been developed to enable users with a diverse range of botanical expertise to identify Juncus to species level. The best time for collection, survey or identification is usually from December to April as mature fruiting material is required to distinguish between species.

  • Tri-Trophic Interactions of a Predator- Parasite-Host Assemblage in New Zealand
    Tri-trophic interactions of a predator- parasite-host assemblage in New Zealand BY KIRSTY JANE YULE A thesis submitted to Victoria University of Wellington in fulfilment of the requirements for the degree of Doctor of Philosophy Victoria University of Wellington (2016) 1 2 This thesis was conducted under the supervision of Associate Professor Kevin Burns (Primary Supervisor) Victoria University of Wellington, New Zealand 3 4 Abstract Parasites are ubiquitous and the antagonistic relationships between parasites and their hosts shape populations and ecosystems. However, our understanding of complex parasitic interactions is lacking. New Zealand’s largest endemic moth, Aenetus virescens (Lepidoptera: Hepialidae) is a long-lived arboreal parasite. Larvae grow to 100mm, living ~6 years in solitary tunnels in host trees. Larvae cover their tunnel entrance with silk and frass webbing, behind which they feed on host tree phloem. Webbing looks much like the tree background, potentially concealing larvae from predatory parrots who consume larvae by tearing wood from trees. Yet, the ecological and evolutionary relationships between the host tree, the parasitic larvae, and the avian predator remain unresolved. In this thesis, I use a system-based approach to investigate complex parasite-host interactions using A. virescens (hereafter “larvae”) as a model system. First, I investigate the mechanisms driving intraspecific parasite aggregation (Chapter 2). Overall, many hosts had few parasites and few hosts had many, with larvae consistently more abundant in larger hosts. I found no evidence for density- dependent competition as infrapopulation size had no effect on long-term larval growth. Host specificity, the number of species utilised from the larger pool available, reflects parasite niche breadth, risk of extinction and ability to colonise new locations.
