title: Watching for invasive species: public engagement

authors: Burton, Tracey

abstract: Invasive species continue to be one of the greatest threats to the Rotorua lakes and include not only water weeds and wallabies, but other organisms too. Invasive molluscs such as zebra and quagga mussels have the potential to cause wide spread devastation to our freshwater ecosystems and are just one example of other invasive aquatic species not yet found in our New Zealand lakes.
The management of invasive species is a shared problem that requires the cooperation and support of a diverse range of stakeholders, interest groups and members of the general public. The early detection of an invasive species is critical and may make the difference in being able to appropriately manage, control or eradiate a species before it has a chance to spread.
Anyone can help prevent the incursion and spread of invasive species into our lakes. In New Zealand, we can learn from the success of programmes in other countries where they are recruiting citizen scientists to look for anything new or unusual. Citizen science,
broadly defined as the involvement of volunteers in research, provides a means of combining research activities with environmental education and public engagement in science. Volunteers are able to increase their knowledge and understanding of the environment, learn more about local issues of importance, and contribute to science based recommendations. In addition, observations collected by citizen scientists can provide valuable records and knowledge that otherwise wouldn’t have been available.

title: Towards a radiocarbon calibration for oxygen isotope stage 3 using New Zealand kauri (Agathis australis)

authors: Turney, Chris S.M.

subjects: New Zealand kauri

abstract: It is well known that radiocarbon years do not directly equate to calendar time. As a result, considerable effort has been devoted to generating a decadally resolved calibration curve for the Holocene and latter part of the last termination. A calibration curve that can be unambiguously attributed to changes in atmospheric ¹⁴C content has not, however, been generated beyond 26 kyr cal BP, despite the urgent need to rigorously test climatic, environmental, and archaeological models. Here, we discuss the potential of New Zealand kauri (Agathis australis) to define the structure of the ¹⁴C calibration curve using annually resolved tree rings and thereby provide an absolute measure of atmospheric ¹⁴C. We report bidecadally sampled ¹⁴C measurements obtained from a floating 1050-yr chronology, demonstrating repeatable ¹⁴C measurements near the present limits of the dating method. The results indicate that considerable scope exists for a high-resolution ¹⁴C calibration curve back through OIS-3 using subfossil wood from this source.

title: Mates at the school gates:Investigating peer relationships among rangatahi Māori

authors: Knowles, Anthea Heather

subjects: school attendance

abstract: As a teacher, I have found that while some rangatahi feel connected to school, many others do not. In an attempt to reduce the gap between Māori and non-Māori educational achievement, there have been significant nationwide initiatives implemented into schools across New Zealand. These programmes have been centred mostly around improving school engagement. Despite these efforts, school attendance rates among Māori continue to decline. This thesis explores the role of peer relationships among rangatahi Māori, including how these relationships may influence various domains of engagement at school, such as participation, belonging and orientation to learning. 

This research involves focus group interviews with six rangatahi Māori aged 17-18, and in Years 12 and 13 in a small-town New Zealand High School. The wāhine Māori who contributed to the study, had been identified by the school as successfully engaged through regular attendance and participation of school activites. The findings from this study identify some critical aspects to building strong peer relationships, including: having a social space to gather, practicing manaakitanga, recognising equity, maintaining connection with each other, and welcoming humour. The rangatahi in this study value their peers and social relationships and they freely access these resources as needed. In doing so they are able to collectively critique experiences of marginalisation and acquire a collective source of resilience. The participants in this study then draw on this collective resilience during challenging situations.
