title: Spatial variation of structural and functional indicators in a large New Zealand river

authors: Collier, Kevin J.

subjects: spatial variability

abstract: The ecological responses of large rivers to human pressure can be assessed at multiple scales using a variety of indicators, but little is known about how the responses of ecological indicators vary over small spatial scales. We sampled phytoplankton, zooplankton and macroinvertebrates and measured river metabolism and cotton strip breakdown rates (loss in tensile strength) in contrasting habitats along a 21-km urban-industrial reach on a constrained section of the Waikato River, New Zealand's longest river. Rates of gross primary production (2.8–7.8 g O₂/m²/d) and ecosystem respiration (3.5–12.7 g O₂/m²/d) did not differ consistently between near-shore (2–3 m from river side) and far-shore (ca. 10 m from side) locations, urban and industrial reaches or between autumn and spring sampling occasions. Rates of cotton decay (−k) ranged from 0.014 to 0.112 per day and were typically faster at far-shore locations and in the section of river receiving industrial inputs, but slower in spring compared with autumn. Nonmetric multidimensional scaling analysis of phytoplankton and zooplankton data did not reveal spatial patterns relating to pressure or location (embayment, edge, mid-river). However, the macroinvertebrate ordination suggested distinct communities for the mid-river benthos compared with near-shore communities and a distinction between sites in the urban reach and the industrial reach. Our results suggest that large-river macroinvertebrate communities and cotton decay rates can be influenced to varying degrees by reach-scale pressures and local habitat conditions. Monitoring designs in spatially complex rivers should account for habitat heterogeneity that can lead to differences in structural and functional indicator responses.

title: Strengthening belonging and identity of refugee and immigrant children through early childhood education

authors: Mitchell, Linda

abstract: This project explored the role of early childhood education (ECE) and pedagogical strategies in supporting a sense of belonging and identity for refugee and immigrant children and families in Aotearoa New Zealand. We used a design-based research methodology in four culturally diverse ECE settings to develop and trial theories and strategies about how ECE can deliberately encourage refugee and immigrant children to connect with their home countries, sustain their cultural identity, and simultaneously live within and contribute to Aotearoa New Zealand. We analysed the affordances of drawing, storytelling and play, and of teacher engagement with children, parents, and whānau, for constructing pathways to belonging in Aotearoa New Zealand. The research focus was on the potential of early childhood services to be sites for social justice for refugee and immigrant children and families, laying a foundation for a confident transition to a bicultural Aotearoa, additional to their own culture. Through the research, we wanted to develop practice strategies and theories of bicultural belonging and participatory democracy that can be strengthened through early childhood education.
