Chondrostereum Purpureum

Chondrostereum purpureum is a basidiomycete fungus that is being investigated as an inundative biological control agent for invasive woody weeds This study was conducted to assess the susceptibility of seven species of weeds to C purpureum The species that were inoculated in this trial were broom (Cytisus scoparius) gorse (Ulex europeaus) buddleia (Buddleja davidii) Himalayan honeysuckle (Leycesteria formosa) hawthorne (Crataegus monogyna) poplar (Populus trichocarpa) and willow (Salix matsudana) Two isolates of C purpureum and a control were used and were each replicated 12 times All plants were potted and the trial took place under nursery conditions Mortality and canker size were measured 6 months after inoculation Data were analysed using SAS The highest mortality (50) was recorded for broom with one isolate but very little mortality was observed across the other species A highly significant weed by isolate interaction was observed with regards to lesion length with weed species susceptibility varying with respect to one of the C purpureum isolates Hawthorn and willow had greater lesion lengths after inoculation with the same isolate that had caused mortality in broom The results from this trial are being used to direct a larger field trial

Chondrostereum Purpureum

The mitochondrial DNA (mtDNA) of Chondrostereum purpureum (Pers.:Fr.) Pouzar was extracted and purified, and the size ranged from 51.8 to 66.4 kb. One isolate each from British Columbia, Alberta, Finland, the Netherlands, and New Zealand were found to have identical BamHI mtDNA restriction patterns, resulting in a mitochondrial genome of 63.8 kb. An additional isolate from British Columbia and one from Switzerland had different banding patterns, however, resulting in mitochondrial genomes of 66.4 kb and 51.8 kb, respectively. A sequence-characterized amplified region (SCAR) assay, based on a polymerase chain reaction, was developed to rapidly screen a larger population of 84 isolates from North America, Europe, and New Zealand. Two SCARs, one encoding the NADH 4 gene (3 kb) and the second encoding the ATPase VI and cytochrome b genes (5.1 kb), were digested with 24 restriction enzymes. There were no polymorphisms in the NADH 4 containing SCAR, while a single polymorphism was detected by NsiI in the ATPase VI - cytochrome b containing SCAR. Two mitochondrial haplotypes that were distributed throughout the sample population were thus identified. The coancestry coefficient (<$Q7A0D00000010446D80BFFEFF88A524F5343905055B98C420120907B4DDA9ECB1F0>) for all subpopulations of the sample population was calculated to be 0.0353. The level of gene diversity in the mtDNA ofC. purpureum suggested that the chance introduction of novel mitochondrial genes following biological control applications of the fungus is relatively low.

Coccinella Undecimpunctata

The introduction of the eleven-spotted ladybird Coccinella undecimpunctata to New Zealand in 1874 has been widely quoted as the first importation of an insect for biological control in New Zealand and one of the first anywhere. However, searches of historical records show no evidence that such an introduction was made or attempted. Instead, there is clear evidence that the presently accepted record arose by a process of cumulative misreporting. An account of discussions in the Entomological Society of London in December 1873 about possible introductions of various beneficial insects to New Zealand was misreported by the American entomologist C. V. Riley, and several subsequent authors restated his version with further modifications and additions. This created the record of the introduction of C. undecimpunctata to New Zealand in 1874 that has been accepted and repeated ever since.

Kia ora and welcome to the second issue of BackStory. The members of the Backstory Editorial Team were gratified by the encouraging response to the first issue of the journal. We hope that our currentreaders enjoy our new issue and that it will bring others to share our interest in and enjoyment of the surprisingly varied backstories of New Zealand’s art, media, and design history. This issue takes in a wide variety of topics. Imogen Van Pierce explores the controversy around the Hundertwasser Art Centre and Wairau Māori Art Gallery to be developed in Whangarei. This project has generated debate about the role of the arts and civic architecture at both the local and national levels. This is about how much New Zealanders are prepared to invest in the arts. The value of the artist in New Zealand is also examined by Mark Stocker in his article about the sculptor Margaret Butler and the local reception of her work during the late 1930s. The cultural cringe has a long genealogy. New Zealand has been photographed since the 1840s. Alan Cocker analyses the many roles that photography played in the development of local tourism during the nineteenth century. These images challenged notions of the ‘real’ and the ‘artificial’ and how new technologies mediated the world of lived experience. Recorded sound was another such technology that changed how humans experienced the world. The rise of recorded sound from the 1890s affected lives in many ways and Lewis Tennant’s contribution captures a significant tipping point in this medium’s history in New Zealand as the transition from analogue to digital sound transformed social, commercial and acoustic worlds. The New Zealand Woman’s Weekly celebrates its 85th anniversary this year but when it was launched in 1932 it seemed tohave very little chance of success. Its rival, the Mirror, had dominated the local market since its launch in 1922. Gavin Ellis investigates the Depression-era context of the Woman’s Weekly and how its founders identified a gap in the market that the Mirror was failing to fill. The work of the photographer Marti Friedlander (1908-2016) is familiar to most New Zealanders. Friedlander’s 50 year career and huge range of subjects defy easy summary. She captured New Zealanders, their lives, and their surroundings across all social and cultural borders. In the journal’s profile commentary Linda Yang celebrates Freidlander’s remarkable life and work. Linda also discusses some recent images by Friedlander and connects these with themes present in the photographer’s work from the 1960s and 1970s. The Backstory editors hope that our readers enjoy this stimulating and varied collection of work that illuminate some not so well known aspects of New Zealand’s art, media, and design history. There are many such stories yet to be told and we look forward to bringing them to you.

This is a biography of Ta’isi O. F. Nelson, the Sāmoan nationalist leader who fought New Zealand, the British Empire and the League of Nations between the world wars. It is a richly layered history that weaves a personal and Pacific history with one that illuminates the global crisis of empire after World War One. Ta’isi’s story weaves Sweden with deep histories of Sāmoa that in the late nineteenth century became deeply inflected with colonial machinations of Germany, Britain, New Zealand and the U. S.. After Sāmoa was made a mandate of the League of Nations in 1921, the workings and aspirations of that newly minted form of world government came to bear on the island nation and Ta’isi and his fellow Sāmoan tested the League’s powers through their relentless non-violent campaign for justice. Ta’isi was Sāmoa’s leading businessman who was blamed for the on-going agitation in Sāmoa; for his trouble he was subjected to two periods of exile, humiliation and a concerted campaign intent on his financial ruin. Using many new sources, this book tells Ta’isi’s untold story, providing fresh and intriguing new aspects to the global story of indigenous resistance in the twentieth century.
