The Family

Aspleniaceae is one of the largest fern families. It is species-rich in Australasia and the south-western Pacific (ASWP), where approximately 115 species occur. In the current study, the chloroplast regions rbcL, trnL–trnF and rps4–trnS were sequenced for 100 Aspleniaceae samples from ASWP. These data were combined with published sequences for species from New Zealand and other regions for phylogenetic analyses. Species of Aspleniaceae from ASWP were placed in six of the eight previously identified inter-continental clades. The majority of species from ASWP were placed in two of these clades, with the remaining four clades each being represented by three or fewer species. Strong biogeographic affinities with South-east Asia were observed and immigration, rather than local radiations of endemic taxa, appears to have made a more important contribution to patterns of diversity in ASWP. This study supports the current taxonomic practice of recognising two genera, Asplenium L. and Hymenasplenium Hayata, in Aspleniaceae, and identifies future taxonomic work required for the family in this region, including potential synonymising of species, and revision of species complexes or widespread species that are demonstrably non-monophyletic.

The South-east Asian and Oceanian fauna of the ant genus Calyptomyrmex is revised. Sixteen species are known from this region, 14 of which are newly described. These include asper sp. n., beccarii Emery, caledonicus sp. n., danum sp. n., fragarus sp. n., fritillus sp. n., grammus sp. n., lineolus sp. n., loweryi sp. n., ocullatus sp. n., rectopilosus Dlussky & Radchenko, retrostriatus sp. n., ryderae sp. n., sabahensis sp. n., sparsus sp. n. and taylori sp. n. The names emeryi Forel and glabratus Viehmeyer are synonymised under beccarii, the only widespread species in the region. All species are associated with rainforest habitats and most have been collected a limited number of times.

Widespread Species

A morphometric study was undertaken to survey taxa in the genus Euchiton Cass., distributed across Australia, New Zealand and South-east Asia. Phenetic analyses of herbarium specimens showed several taxa to be well delimited, including E. brassii (Mattf.) Anderb., E. breviscapus (Mattf.) Anderb., E. lateralis (C.J.Webb) Breitw. & J.M.Ward, E. limosus (D.G.Drury) Holub, E. litticola A.M.Buchanan, E. traversii (Hook.f.) Holub and E. umbricola (J.H.Willis) Anderb. However, the analyses showed that the remainder of Euchiton taxa are not yet satisfactorily resolved taxonomically. The distributions of E. involucratus (G.Forst.) Holub and E. sphaericus (Willd.) Holub were elucidated, although these widespread species would benefit from more research. Further research is necessary into species delimitation between E. paludosus (Petrie) Holub and E. polylepis (D.G.Drury) Breitw. & J.M.Ward and within the E. japonicus complex, including E. audax (D.G.Drury) Holub, E. collinus Cass., E. delicatus (D.G.Drury) Holub, E. ensifer (D.G.Drury) Holub, E. japonicus (Thunb.) Holub and E. ruahinicus (D.G.Drury) Breitw. & J.M.Ward. Recognition of a proposed taxon E. ‘gracilis’ was not supported and description at this point is not recommended. The New Zealand material of E. audax, E. delicatus and E. ensifer was shown to differ from the Australian material in the micromorphology of the cypselae. Euchiton collinus is considered a synonym of E. japonicus, which also includes the Australian material attributed to E. audax, E. delicatus and E. ensifer. The presence of E. limosus in Australia was confirmed, with it differing from E. involucratus in having glabrous cypselae with paired papillae in both Australian and New Zealand material. Generic boundaries of Euchiton are problematic. The generic placement of Gnaphalium clemensiae Mattf. and E. umbricola remains unresolved. Insufficient data were available to make taxonomic conclusions regarding the generic placement of G. chiliastrum (Mattf.) P.Royen and G. heleios P.Royen from New Guinea.

Market Learning

A model of market behavior as a learning process was explored using artificial neural networks. Market and currency data from the period before and during the South-East Asia crisis of 1997 relating to Indonesia, the Philippines, Malaysia, Thailand, Australia, and New Zealand was used to train neural networks. Time series of changes in neural networks' connection weights were generated whilst making a series of forecasts over time. Changes in connection weights captured the changing importance of these Asian markets to those of Australia and New Zealand as the crisis unfolded, and could be regarded as a measure of market learning.

At Home

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.
