title: Food webs in forest and pasture streams in the Waikato region, New Zealand:  A study based on analyses of stable isotopes of carbon and nitrogen, and fish gut contents.

authors: Hicks, Brendan J.

subjects: stable isotopes

abstract: Stable isotopes of carbon (C) and nitrogen (N) were studied in 11 stream communities in the Waikato region of New Zealand. From comparisons of mean d13C and d15N values, food webs in the shaded, forest streams were clearly based on allochthonous material (conditioned leaf litter and terrestrial invertebrates). Autotrophs in forest streams were not a significant C source for the food webs. However, the C source of food webs in the unshaded pasture streams appeared to be a mixture of allochthonous and autochthonous material. Conditioned leaf litter appeared to contribute to the pasture stream food webs, and the d13C and d15N of some samples of epilithic diatoms indicated their consumption by invertebrates in pasture streams. Fish ate a wide range of aquatic invertebrates; longfinned eels (Anguilla dieffenbachiai) and banded kokopu (Galaxias fasciatus) also had a large proportion of terrestrial invertebrates in their diet. Filamentous green algae were found only at pasture sites, where they were sometimes abundant. The wide range of d13C values of filamentous green algae (-18.8 to -29.7[[perthousand]]) complicated understanding of their role in the stream food webs. The d13C values of Cladophora were related to water velocity, with more 13C-enriched values in pools than in runs (-23.2[[perthousand]] in pools, mean velocity 0.12 m s-1; -28.1[[perthousand]] in runs, mean velocity 0.24 m s-1). Crayfish and the gastropod mollusc Potamopyrgus appeared to be the only invertebrates to eat filamentous green algae.

title: Evaluating research - Peer review team assessment and journal-based bibliographic measures: New Zealand PBRF research output scores in 2006

authors: Anderson, David L.

subjects: Bibliometrics

abstract: This paper concerns the relationship between the assessment of the research of individual academics by peer or expert review teams with a variety of bibliometric schemes based on journal quality weights. Specifically, for a common group of economists from New Zealand departments of economics the relationship between Performance-Based Research Fund (PBRF) Research Output measures for those submitting new research portfolios in 2006 are compared with evaluations of journal based research over the 2000-2005 assessment period. This comparison identifies the journal weighting schemes that appear most similar to PBRF peer evaluations. The paper provides an indication of the ‘power or aggressiveness’ of PBRF evaluations in terms of the weighting given to quality. The implied views of PBRF peer review teams are also useful in assessing common assumptions made in evaluating journal based research.

title: Hoea Te Waka ki Uta: Critical Kaupapa Māori Research and Mormon Studies Moving Forward

authors: Simon, Hemopereki

abstract: The following is a reflective commentary on the place of Critical Indigenous Studies, with a focus on Kaupapa Māori Research, within Mormon Studies. Specifically, the piece explores the following questions: What does Kaupapa Māori Research look like when engaging in Mormon Studies? What positionality needs to be taken by Kaupapa Māori researchers and Critical Indigenous scholars when engaging in Mormon Studies? What are the main areas Critical Indigenous scholars and Kaupapa Māori scholars should engage when tackling issues around Mormonism? These questions are important in light of the growing importance of the cultural renaissance in Te Ao Māori and the rise of Kaupapa Māori Research.
