title: Further evidence for the effect of particle-size diversity on deep-sea benthic biodiversity

authors: Leduc, Daniel

subjects: Habitat heterogeneity

abstract: The positive correlation between sediment particle-size diversity (a measure of habitat heterogeneity) and deep-sea macrofaunal diversity was first demonstrated two decades ago. The causality of this relationship was not elucidated because of the potential influence of macrofauna on sediment granulometry. Here we test the generality of this correlation using smaller organisms with limited mobility and limited ability to change the physical structure of sediments. Results of partial regressions accounting for the effect of water depth and food availability showed that nematode species and genus diversity were positively correlated with sediment particle-size diversity on the continental slope of New Zealand. Trophic diversity was not correlated with sediment particle-size diversity, however, which could suggest that the relationship between habitat heterogeneity and diversity was not the result of food partitioning between species/genera. Our findings provide support for the importance of small-scale habitat heterogeneity in the maintenance of local diversity in the deep sea, one of the few known environmental factors that may directly influence species co-existence in this biome.

title: Review: Encyclopedia of linguistics

authors: Barnard, Roger

subjects: linguistics

abstract: The two volumes of this new encyclopedia contain over five hundred self-contained essays, each between 1000 and 3000 words, covering a very wide range of topics. They have been written by some three hundred specialists from 34 countries (including several from New Zealand) who were invited to write for readers with no specialist knowledge of the subject by the reader, and without going into considerable theoretical detail. The essays are all very clearly written, and each provides a succinct introduction to the subject. In all cases, suggestions for further reading are provided, as are cross-references to related topics elsewhere in the encyclopedia.

title: Maori perspectives of the environment: A review of resource use consent submissions made by iwi to Environment Waikato.

authors: Whangapirita, Laura

subjects: Maori

abstract: As part of our broader brief to gather, summarise, analyse and distribute information held by Environment Waikato on Maori and the environment, we reviewed and summarised iwi consent submissions made on various resource use consent applications. This report refers to values and beliefs sourced from iwi submissions held by Environment Waikato and are presented within a Maori values framework to highlight environmental perspectives of tangata whenua in the Waikato region.
