title: Co- variation in soil biodiversity and biogeochemistry in northern and southern Victoria Land, Antarctica

authors: Barrett, John E.

subjects: habitat suitability

abstract: Data from six sites in Victoria Land (72–77°S) investigating co-variation in soil communities (microbial and invertebrate) with biogeochemical properties showthe influence of soil properties on habitat suitability varied among local landscapes as well as across climate gradients. Species richness of metazoan invertebrates (Nematoda, Tardigrada and Rotifera) was similar to previous descriptions in this region, though identification of three cryptic nematode species of Eudorylaimus through DNA analysis contributed to the understanding of controls over habitat preferences for individual species. Denaturing Gradient Gel Electrophoresis profiles revealed unexpectedly high diversity of bacteria. Distribution of distinct bacterial communities was associated with specific sites in northern and southern Victoria Land, as was the distribution of nematode and tardigrade species. Variation in soil metazoan communities was related to differences in soil organic matter, while bacterial diversity and community structure were not strongly correlated with any single soil property. There were no apparent correlations between metazoan and bacterial diversity, suggesting that controls over distribution and habitat suitability are different for bacterial and metazoan communities. Our results imply that top-down controls over bacterial diversity mediated by their metazoan consumers are not significant determinants of bacterial community structure and biomass in these ecosystems.

title: Queering public transport: Understanding access for Aotearoa queer communities

authors: Crossland, Kiri

subjects: Public transport

abstract: Queer people face inequitable access to public transport. International literature suggests that queer people are more likely to be transit dependent, but at the same time more likely to experience discrimination, harassment or violence while using it. However, little is known about what makes public transport attractive or accessible to this group. This thesis seeks to address this through a survey of 347 public transport users (half of whom are queer) to understand this issue in an Aotearoa context. The results show the main factors influencing the attractiveness and accessibility of public transport to queer people are not feeling safe, lack of transport choice, long journey times, and affordability. Straight people are also influenced by these factors, however at lower rates. Interventions that could improve public transport attractiveness and accessibility for queer people were also identified. Safety improvements such as more frequent services, safety interventions along walking routes to public transport, and staff training are key to improving queer public transport access. Improving travel times to reduce queer exposure to discrimination and harassment is also important. Engagement with queer people is key to ensuring interventions are appropriate for local contexts. The survey also showed that police presence is unlikely to improve queer feelings of safety. This research was the first study of queer people’s access to public transport in Aotearoa and offers important practical insights as to how planners can support a just transition to a low emissions transport future.

title: Breaking barriers and empowering perspectives: Centering women's voices in the mongrel mob wāhine toa

authors: Arnold, Annaliese

subjects: gang research

abstract: Gang communities in Aotearoa New Zealand have traditionally been sites of masculinity where specific forms of 'maleness' - including resistance to authority, antisocial behaviour, and expressions of violence - are embraced, expressed, and enforced through various internal cultural norms and reactions to the outside world. The dominant narrative that informs public perceptions of New Zealand gangs is often centered on crime, poverty, and Indigeneity. Much less is known about the role of women in these communities, particularly as their voices have only recently emerged from one of the largest gang chapters in the country. This research, conducted in close collaboration with wāhine within the Mongrel Mob Kingdom's first female-only chapter, Mongrel Mob Wāhine Toa, uses a participatory action research approach with photovoice methodology. Drawing on the personal narratives of six wāhine, this study aims to better understand their perspectives and experiences of contributing to a fledgling movement that privileges women within a predominantly male-centered gang environment. Photovoice is used alongside semi-structured interviews to provide depth and breadth to the data, allowing the wāhine to visually and verbally express their experiences and perspectives. Themes include navigating marginality, empowerment, and resistance. The long-range goal of this work is to inform context-sensitive policies and interventions for wāhine in gangs in Aotearoa. By foregrounding the perspective of wāhine, this study contributes to breaking down barriers and reshaping discourses around women in gangs, with implications for well-being and empowerment.
