title: Remnants of the past, history and the present.

authors: Booth, Douglas

subjects: education

abstract: The article interprets that it is hardly surprising then that philosophers of history point to the slender relationship between the raw facts of the past and understanding the past. The latter is an act of interpreting fragments from the past and not infrequently these support several points of view. This question has particular significance at a time when historians are increasingly thinking about historical materials and evidence in radically new ways that are fundamentally changing the nature of history as an academic discipline. In the light of these changes, the first part of the article sketches three different sets of epistemological assumptions that operate in contemporary history; the second applies these assumptions to a more detailed analysis of four pieces of historical material. Reflecting on the analysis in part two, the conclusion discusses the complex relations between the present and the past.

title: Abundance of small individuals influences the effectiveness of processing techniques for deep-sea nematodes

authors: Leduc, Daniel

subjects: continental slope

abstract: Nematodes are the most abundant metazoans of deep-sea benthic communities, but knowledge of their distribution is limited relative to larger organisms. Whilst some aspects of nematode processing techniques, such as extraction, have been extensively studied, other key elements have attracted little attention. We compared the effect of (1) mesh size (63, 45, and 32 μm) on estimates of nematode abundance, biomass, and body size, and (2) microscope magnification (50 and 100×) on estimates of nematode abundance at bathyal sites (250-3100 m water depth) on the Challenger Plateau and Chatham Rise, south-west Pacific Ocean. Variation in the effectiveness of these techniques was assessed in relation to nematode body size and environmental parameters (water depth, sediment organic matter content, %silt/clay, and chloroplastic pigments). The 63-μm mesh retained a relatively low proportion of total nematode abundance (mean ±SD = 55 ±9%), but most of nematode biomass (90 ± 4%). The proportion of nematode abundance retained on the 45-μm mesh in surface (0-1 cm) and subsurface (1-5 cm) sediment was significantly correlated (P < 0.01) with %silt/clay (R² = 0.39) and chloroplastic pigments (R² = 0.29), respectively. Variation in median nematode body weight showed similar trends, but relationships between mean nematode body weight and environmental parameters were either relatively weak (subsurface sediment) or not significant (surface sediment). Using a low magnification led to significantly lower (on average by 43%) nematode abundance estimates relative to high magnification (P < 0.001), and the magnitude of this difference was significantly correlated (P < 0.05) with total nematode abundance (R²p = 0.53) and the number of small (≤ 250 μm length) individuals (R²p = 0.05). Our results suggest that organic matter input and sediment characteristics influence the abundance of small nematodes in bathyal communities. The abundance of small individuals can, in turn, influence abundance estimates obtained using different mesh sizes and microscope magnifications.

abstract: Tā tēnei tuhinga, he titiro ki ngā kōrero onamata mō ngā mahi nōnoke a te Māori. I mua, whāia ai te nōnoke e ētehi hapori Māori hei koringa tinana, hei tū hākinakina, hei tākaro hoki. Ko te nōnoke, te whātōtō, te taitai me te mamau, he rite katoa. Nō te kuhutanga mai o ngā tini whakaawenga a tauiwi, ka nui hoki te Māori i tahuri ki hākinakina kē. Nāwhai ā ka mimiti te whāia o te nōnoke. Kei tēnei tuhinga, ka āta wetekina ngā kupu me ngā kōrero o te reo nōnoke o mua, arā ngā tohutohu a ngā pāhake e whakaahua ana i ngā tūmomo neke, i ngā whiu me ngā puringa mahia ai e te kaiwhātōtō. Ka arohaehaetia tēnei mea te karakia, te waiata me te pepeha kia kuhuna ai te hinengaro o te kaiwhātōtō e mārama rawa ai te ia o ōna whakaaro, tōna waiaro me tōna whanonga. Waihoki ko ngā pūrākau o mua, kua whakaemia ētehi tauira kia tīroua ngā karere i whaona ki roto. Ko te tino whāinga, ko te whera i ngā rangahau nei kia āta mōhio ki ngā koronga me ngā horopaki whāia ai e te Māori o mua ngā mahi nōnoke.
