    Origins and diversity of invasive brushtail possums (Trichosurus vulpecula) in New Zealand surveyed with mtDNA haplotype and nuclear microsatellite data
    (Taylor and Francis Group on behalf of the Royal Society of New Zealand, 2025-05-07) Pattabiraman N; Morgan-Richards M; Trewick SA; Su J
    The brushtail possum Trichosurus vulpecula is native to Australia where six subspecies exist in distinct regions. A composite invasive population is established in Aotearoa New Zealand, which has since been subject to localised bouts of culling. We surveyed population genetic structure across New Zealand to identify the scale of genetic diversity introduced to New Zealand and the resulting pattern of admixture. Australian brushtail possums have high mitochondrial diversity (17%) and prominent spatial structure. Thirty-eight haplotypes among 25 New Zealand population samples (n = 465) were closely related to 45 haplotypes sampled from Victoria and Tasmania in Australia (n = 120), but just one was shared. High haplotype diversity is consistent with multiple successful introductions and rapid population expansion in New Zealand. Nuclear diversity of microsatellite loci screened in 18 New Zealand population samples (n = 374) comprised five genotypic clusters (K = 5), but these groups did not correlate with geography. An overall signal of genetic partitioning within the invasive population suggests limited mixing but ongoing management towards eradication will influence patterns of population recovery, migration and evolution of traits including toxin resistance. We consider the implications of mixed ancestry of the invasive population in terms of variation in toxin tolerance detected in New Zealand.

    The influence of host receptivity and conformity pressure on the intercultural transformation of Filipino migrants in New Zealand
    (Elsevier B.V., 2024-12-17) Separa LAC; Croucher SM; Hodis GM; Feekery A
    Filipinos are the second fastest-growing Asian population working in dairy farming, healthcare, construction, and other industries in New Zealand. Like other immigrants, Filipinos experience basic and advanced intercultural transformation as they communicate and interact with people in the country. Croucher and Kramer's cultural fusion theory proposes a positive relationship between host receptivity and intercultural transformation and a negative relationship between host conformity pressure and intercultural transformation. Employing a survey of 315 Filipino migrants in New Zealand, this study addresses the extent to which host receptivity and host conformity pressure affect intercultural transformation. Regression analysis is used to assess the hypotheses and research question. Results reveal both host receptivity and host conformity pressure have positive relationships with intercultural transformation. The potential role of media and Filipino values in this study are also discussed.

    A new season for climate change science and praxis?
    (Walter de Gruyter GmbH, 2024-01-29) Glavovic B; Bremer S; Wardekker A
    I write these reflections at the end of the 27th Conference of Parties meeting of governments (COP27), held in Egypt in November 2022, at which governments sought to progress climate action. COP27 was informed by the Sixth Assessment Report (AR6) by the Intergovernmental Panel on Climate Change (IPCC). Established in 1988, the IPCC provides UN member nations with comprehensive assessments of the state of climate change science and its implications. I spent much of 2017–2022 devoted to AR6. I was a Coordinating Lead Author of the chapter on sea-level rise in the IPCC’s Special Report on the Ocean and Cryosphere in a Changing Climate (1), Lead Author of the chapter on Climate Resilient Development, and co-lead for the Cross-Chapter Paper on Cities and Settlements by the Sea, in the Working Group II report (2). How can I convey the gravitas of the climate predicament outlined in AR6? Moreover, where do we stand now – after more than three decades of intensive climate change science-policy interactions? What does this portend for climate change scientists, policy advisors and elected politicians? What does it mean for you and I? And how might answers to these questions inform our understanding about seasons; and how we might navigate impending dangerous climate change?

    Managed retreats by whom and how? Identifying and delineating governance modalities
    (Elsevier B.V, 2021) Hanna C; White I; Glavovic BC
    Managed retreat has become a compelling policy imperative as climate change exacerbates socio-natural hazard risks and imminent harm looms for exposed communities. Retreats may be initiated over different times and scales using various instruments by actors, from the state to the private sector and civil society. However, in the absence of a coherent strategic vision, guiding frameworks, and capacity to manage retreats, at-risk communities, their elected representatives, policy makers, and planners are compelled to embark on retreat governance experiments. Consequently, retreat is perceived as a ‘high regrets’ policy imperative with potentially adverse impacts for community wellbeing, as well as political and professional risks. To help translate managed retreat rhetoric into reality, this paper presents a governance framework that acknowledges the multiplicity of ‘managed retreats.’ Using examples from Aotearoa-New Zealand, we identify and delineate retreat modalities and clarify terminology, converging our framework with the international mobility literature to harness the valuable lessons from decades of human mobility practice.
