title: Testing use of mitochondrial COI sequences for the identification and phylogenetic analysis of New Zealand caddisflies (Trichoptera)

authors: Hogg, Ian D.

subjects: aquatic insects

abstract: We tested the hypothesis that cytochrome c oxidase subunit 1 (COI) sequences would successfully discriminate recognised species of New Zealand caddisflies. We further examined whether phylogenetic analyses, based on the COI locus, could recover currently recognised superfamilies and suborders. COI sequences were obtained from 105 individuals representing 61 species and all 16 families of Trichoptera known from New Zealand. No sequence sharing was observed between members of different species, and congeneric species showed from 2.3 to 19.5% divergence. Sequence divergence among members of a species was typically low (mean = 0.7%; range 0.0–8.5%), but two species showed intraspecific divergences in excess of 2%. Phylogenetic reconstructions based on COI were largely congruent with previous conclusions based on morphology, although the sequence data did not support placement of the purse-cased caddisflies (Hydroptilidae) within the uncased caddisflies, and, in particular, the Rhyacophiloidea. We conclude that sequence variation in the COI gene locus is an effective tool for the identification of New Zealand caddisfly species, and can provide preliminary phylogenetic inferences. Further research is needed to ascertain the significance of the few instances of high intra-specific divergence and to determine if any instances of sequence sharing will be detected with larger sample sizes.

title: Biostratigraphy, Sr isotope chronology and chronostratigraphy of the Late Eocene – earliest Miocene Te Kuiti Group, Waikato – King Country Basin, New Zealand

authors: Kamp, Peter J.J.

abstract: This report reviews and synthesises the biostratigraphy of the Te Kuiti Group based on existing sample data archived in the Fossil Record Electronic Database (FRED). Based on these faunal and floral data, New Zealand biostratigraphic stages for the Late Eocene to Early Miocene are assigned to the formations and members within the group. Analytical strontium (Sr) data and resulting numerical ages are reported here for 26 new macrofossil samples from the Te Kuiti Group, but they do not improve the accuracy of the biostratigraphy and the age information that can be derived from it. The identification of unconformity-bound sequences, the boundaries of which align with the formation contacts within the group, provide an important set of time planes within the group. The integration of the biostratigraphy and sequence stratigraphy produces a robust chronostratigraphy for the Te Kuiti Group.

title: “Whānau Vibes”: Reclamation of self, space and community within group fitness gyms.

authors: Metekingi, Cydney

abstract: Group fitness gyms are becoming more popular in Aotearoa, New Zealand. This thesis is an investigation of the lived experiences of Māori members within a commercialised fitness space called BFT Hamilton East, located in Kirikiriroa, Hamilton. Drawing on Indigenous anthropology and autoethnography, and grounded in Kaupapa Māori theory, this thesis firstly explores how the gym becomes a site in which Māori members seek to reclaim the narrative around their own bodies. I explore the colonial depictions, the politics of the Indigenous body and how Māori-owned clothing brands contribute to this reclamation. I then examine how Māori gym members use the gym space with a sense of purpose, balancing the values of culture and commercialisation. And finally, I investigate the importance of relational well-being and the use of whanaungatanga and manaakitanga to create a sense of belonging among participants in their search for connection. In foregrounding Indigenous ways of knowing, being and moving in a commercial group fitness gym, this thesis aims to contribute to the anthropological conversations that advocate for the inclusion of Indigenous methodologies into Anthropology, centring Indigenous agency and advocating for the decolonisation of fitness spaces.
