Meiofaunal thiobios and 'the Arenicola negation': Case not proven

, : Meiofaunal thiobios and 'the Arenicola negation': Case not proven. Marine Biology (Berlin): 581: 25-29

The distribution of meiofauna around Arenicola burrows may disprove the existence of a specifically anaerobic marine meiofauna. Critical appraisal of the evidence on which this denial was based is discussed. It may have arisen mistakenly from inadequate sampling of the burrow micro habitats, from lack of complementary data on burrow wall O2 regime and from prejudgement (by denying the possibility of primary anaerobiosis) of the reasons why species held to be anaerobic occur in proximity to oxic conditions. These points and some new data on Arenicola burrow oxygenation are examined. The evidence from meiofaunal distribution around Arenicola burrows may be taken as much in favor of thiobiotic theories as against them.

We present the preliminary results of a detailed investigation of the shock effects in highly shocked, low density sedimentary rocks from the Haughton impact structure. We suggest that some textural features can be explained by carbonate-silicate...

A methanol extract of chaste-tree berry (V. agnus-castus) was tested for its ability to displace radiolabelled estradiol from the binding site of oestrogen receptors alpha (ER alpha ) and beta (ER beta ). The extract at 46+or-3 micro g/ml displace...

Purpose: To compare the repair efficiency of X-ray (low linear energy transfer (LET)) and nitrogen ion (high LET)-induced single-strand breaks (SSB) in a human cell-free end-joining system. Materials and methods: SSB were introduced into a bacteri...
