    Description: Lophelia pertusa plays an important role as a major contributor to many cold-water coral reefs, supporting a high diversity of associated benthic and benthopelagic species. Due to the high sensitivity of L. pertusa to human activity, it has been classified as indicator species for Vulnerable Marine Ecosystems. However, the global spatial distribution of L. pertusa is far from well known. In this study, a database of L. pertusa presence data was compiled derived from the large number of L. pertusa occurrence records appearing in recent years. In conjunction with data layers covering a range of environmental drivers, habitat suitability for L. pertusa was predicted using the Random Forest approach. Suitable habitat for L. pertusa was predicted to occur primarily on continental margins, with the most suitable habitat likely to occur in the North East Atlantic and South Eastern United States of America. Aragonite saturation state, temperature and salinity were identified as the most important contributors to the habitat suitability model. Given the high vulnerability of reef-forming cold-water corals to anthropogenic impacts, habitat suitability models are critical in developing worldwide conservation and management strategies for biodiverse and biomass rich cold-water coral ecosystems.

    Notes: [Auszug] Both oxygen atoms in the resultant peroxide thus originate in the hydrogen peroxide molecule. This must necessarily be the case in reaction (3), but it is also thought to apply in reactions of types (1) and (2). The reaction may proceed by either of the two established mechanisms of nucleophilic ...

    Notes: [Auszug] ON the morning of Saturday, Jan. 31, after a frosty night, we discovered in the bird-bath on the lawn a remarkable ice structure. The bath is a circular metal basin, 10 in. in diameter at the rim, with a concave base admitting of a maximum depth of 2 in. of water in the centre. There was a ...

    Notes: The Arrhenius parameters for the unimolecular lactonisation of the K-salts of the ω-brom-undecanoic and ω-brom-pentadecanoic acids have been determined. It has been shown that the reaction rate depends on the ionisation of the bromine, not on the cyclisation process. The observations have been discussed and, in particular, an explanation in kinetic terms is provided for the minimum yield of cyclic products near C11.
