New Zealand is an island continent that completed its split from the Gondwanan continent at 52 Ma, harbouring an iconic biota of tuatara, kiwi and weta. The sooty mould community is a distinctive trophic element of New Zealand forest ecosystems that is driven by plant-feeding sternorrhynchan Hemiptera. These produce honeydew, which supports fungal growth, which in turn supports numerous endemic invertebrates, including endemic New Zealand beetle families. Ancient New Zealand insect fossils are rare but a single fossil of a sooty mould cyclaxyrid was recently described from Cretaceous Burmese amber, a family that was previously known from two extant New Zealand species. Well-preserved fossils like this one are recasting Earth history, and, based on a wealth of additional specimens, we re-evaluate the taxonomy of Cretaceous cyclaxyrids and one Eocene species here transferred to Cyclaxyridae. Cyclaxyridae are highly tied to the sooty mould community and have now been discovered to occur in disparate biogeographic realms in deep time. Our discovery indicates that the family, and perhaps the sooty mould community in general, was widespread in Pangaea from at least the Cretaceous and survived as a relict in New Zealand. Persistence of a sooty mould ecosystem in New Zealand and fungal specialization may not necessarily be an evolutionary ‘dead-end’ for cyclaxyrids and other insects.

This chapter analyses the earliest of the New Zealand coming-of-age feature films, an adaptation of Ian Cross’s novel The God Boy, to demonstrate how it addresses the destructive impact on a child of the puritanical value-system that had dominated Pākehā (white) society through much of the twentieth century, being particularly strong during the interwar years, and the decade immediately following World War II. The discussion explores how dysfunction within the family and repressive religious beliefs eventuate in pressures that cause Jimmy, the protagonist, to act out transgressively, and then to turn inwards to seek refuge in the form of self-containment that makes him a prototype of the Man Alone figure that is ubiquitous in New Zealand fiction.

To date, the majority of research on migrant identity negotiation and adjustment has primarily focused on adults. However, identity- and adjustment-related issues linked with global migration are not only related to those who have recently arrived, but are also relevant for their subsequent descendants. Consequently, there is increasing recognition by that as a particular group, the “1.5 generation” who were born in their home country but came to new countries in early childhood and were educated there. This research, therefore, investigates 1.5 generation South Koreans’ adjustment and identity status in New Zealand. More specifically, this study explores two vital social spaces—family and school—which play a pivotal role in modulating 1.5 generation’s identity and adjustment in New Zealand. Drawing upon in-depth interviewing with twenty-five 1.5 generation Korean-New Zealanders, this paper reveals that there are two different experiences at home and school; (1) the family is argued to serve as a key space where the South Korean 1.5 generation confirms and retains their ethnic identity through experiences and embodiments of South Korean traditional values, but (2) school is almost the only space where the South Korean 1.5 generation in New Zealand can acquire the cultural tools of mainstream society through interaction with English speaking local peers and adults. Within this space, the South Korean 1.5 generation experiences the transformation of an ethnic sense of identity which is strongly constructed at home via the family. Overall, the paper discusses that 1.5 generation South Koreans experience a complex and contradictory process in negotiating their identity and adjusting into New Zealand through different involvement at home and school.

Abstract Burmese amber continues to provide unique insights into the terrestrial biota inhabiting tropical equatorial forests during mid-Cretaceous time. In contrast to the large amount and great diversity of terrestrial species retrieved so far, aquatic biota constitute rare inclusions. Here we describe the first freshwater snail ever preserved in amber. The new species Galba prima sp. nov. belongs in the family Lymnaeidae, today a diverse and near globally distributed family. Its inclusion in terrestrial amber is probably a result of the amphibious lifestyle typical of modern representatives of the genus. The finding of a freshwater snail on the Burma Terrane, back then an island situated at some 1500 km from mainland Asia, has implications for the dispersal mechanisms of Mesozoic lymnaeids. The Cenomanian species precedes the evolution of waterfowl, which are today considered a main vector for long-distance dispersal. In their absence, we discuss several hypotheses to explain the disjunct occurrence of the new species.

This article considers children’s right to participate in the context of private law disputes concerning their post-separation, day-to-day care and contact arrangements. In New Zealand the approach to ascertaining children’s views has been both long-standing and systematic for contested proceedings within the Family Court (via children’s legal representatives and judicial meetings with children). However, major reform of the family justice system in 2014 shifted the emphasis to new out-of-court processes for resolving post-separation parenting arrangements. The reforms were disappointingly silent on the issue of children’s participation in the new Family Dispute Resolution services, particularly mediation. A disparity has thus arisen between opportunities for children’s engagement in New Zealand’s in-court and out-of-court dispute resolution processes. Research evidence and international developments in Australia and England and Wales are reviewed for the guidance they can offer in remedying this in New Zealand and elsewhere.

<p><b>Epiphytes and other structurally-dependent plants have a spatial ecology and community structure intrinsically linked to that of the host trees in the forest, unlike fully terrestrial plants. Understanding of the ecological implications of this from a theoretical perspective is in its infancy. New Zealand’s south temperate rainforest, whilst not as species rich as tropical forests, hosts one of the richest temperate epiphyte floras. Our understanding of the ecological processes structuring the epiphyte communities of New Zealand forests is however lacking. Here, I present four key studies seeking to add to our knowledge of epiphyte community structure, host specificity and spatial ecology in the New Zealand eco-region.</b></p> <p>First, I tested if seed size determined the likelihood of woody plant species occurring epiphytically on tree ferns (their arboreality) – Chapter 2. Arboreality was negatively related to seed size, with only smaller-seeded species commonly occurring on tree ferns. However, the effect of seed size reduced in later life history stages, as expected. These small-seeded species, most notably Weinmannia racemosa, appear to be utilising an alternative recruitment strategy by establishing epiphytically on the tree fern trunks.</p> <p>Second, on Cyathea dealbata host tree ferns, I tested patterns of species accumulation, metacommunity network structure, and differences in vertical stratification (Chapter 3). Epiphytes and climbers followed a species accumulation model of succession between tree ferns of different sizes and between older and younger portions of the tree fern. The metacommunity network showed patterns of species co-occurrence and nestedness consistent with null expectations. Epiphytes of different habits and different dispersal syndromes show different vertical profiles of occurrence, with bird-dispersed species occurring more often near the top of the tree fern than other taxa.</p> <p>To understand an unusual pattern in epiphyte between-host structuring, I quantified the relationship between epiphytic plant and sooty mould assemblages in New Zealand montane beech forest (Chapter 4). Due to the presence of host specific scale insects, the sooty mould was limited to two of three co-dominant canopy tree species. On these two host species, epiphyte richness was significantly reduced. The host size-richness relationship in these two species was also removed, with species composition significantly altered compared to the mould free host species. My results are consistent with the sooty mould amensally excluding the epiphytes and it can be considered as a part of a keystone species complex (with the host beeches and scale insects). This produces a strong pattern of parallel host specificity otherwise not seen in epiphyte assemblages.</p> <p>Lastly, I compared the differences in spatial niche and host species diversity between three arboreal plants, with divergent ecophysiology, on Lord Howe Island (Chapter 5). These focal species were a dwarf mistletoe, an epiphytic orchid and an epiphytic fern. The mistletoe was restricted to thinner branches, and had a significantly different niche to both epiphyte taxa. The host diversity of the mistletoe and orchid both differed significantly from null model expectations. However, the epiphytic fern (Platycerium bifurcatum) had a host diversity consistent with null expectations.</p> <p>Taken together, these studies increase our understanding of epiphyte community assembly in New Zealand and provide a platform to encourage further work in this field. They also provide results that expand understanding of spatial patterns between host and up vertical clines.</p>

<p>This thesis explores the topic of families during the First World War through a single New Zealand family and its social networks. The family at the core of the thesis, the Stewarts, were a well-to-do Dunedin family who moved in the most exclusive circles of colonial society. As members of the elite, and as prominent figures in the leadership of wartime patriotic organisations, they conceived of their wartime role as one of public benevolence and modelling patriotic virtue for others. Yet, like countless other families, their personal lives were shattered by the war. Drawing upon the extensive records left behind by the Stewart family, as well as associated archives, the thesis advances a number of larger arguments.  It is the overarching claim of this study that families – in their emotional, material and symbolic manifestations – formed an integral part of the war experience and provide a significant way of understanding this global event and its devastating human consequences. The Stewart family’s extensive surviving archive of personal correspondence provides a window into the innermost emotions, beliefs and values of the family’s individual members. Episodes in their wartime lives shape the wider thesis themes: the impact of family separations, grief and bereavement, religious faith, duty and patriotism, philanthropy, the lingering shadow of war disability – and the inflection of all of these by gender and class. Analysing the letters that the family exchanged with other correspondents demonstrates the embeddedness of family in larger networks of association, as well as identifying the aspects of their world view they shared with others in their predominantly middle- and upper-class circles. The records of patriotic organisations members of the family were associated with provide a means of examining how they translated their private beliefs into public influence.  The continual interplay between mobility and distance forms another of the study’s substantive themes. The distance created by the geographical separation between battlefronts and homefronts was a defining feature of the war for families in far-flung dominions such as New Zealand. But distance could be overcome by mobility: through the flow of things, money and people. Such movements, the thesis argues, blurred the boundaries between home and front. Thus, the correspondence members of the Stewart family exchanged during the war enabled them to sustain intimate ties across distance and helped them to mediate their own particular experience of wartime bereavement. The informal personal and kinship networks sustained by the female members of the family formed an important constituent of wartime benevolence, providing a conduit for the flow of information, goods and financial aid across national boundaries. During the war, the leadership of women’s patriotic organisations promoted an essentialised vision of feminine nature to justify their organisations’ separate existence and to stake a claim for women’s wider participation in the war effort. In doing so, they drew upon enlarged notions of kinship to argue that their female volunteers were uniquely qualified to bridge the distances of war, and to bring the emotional and practical comforts of home to frontline soldiers.  An alternative perspective to the Stewart family’s story of war is provided in this thesis through counterpoints from casefiles of the Otago Soldiers’ and Dependents’ Welfare Committee, with which the Stewarts were involved. Here, the economic interdependence and mutual reliance of working-class families is laid bare in ways that differ markedly from the experience of the Stewarts, but which nevertheless underscores the centrality of the family as an institution for people of all social backgrounds. For some families the geographical separation imposed by the exigencies of war proved insurmountable. The very different kinds of families in this thesis illustrate that whether through their successes, or the sometimes dire consequences of their failures, families are nonetheless indispensable to understanding the First World War.</p>
