The NaturePlus Forums will be offline from mid August 2018. The content has been saved and it will always be possible to see and refer to archived posts, but not to post new items. This decision has been made in light of technical problems with the forum, which cannot be fixed or upgraded.

We'd like to take this opportunity to thank everyone who has contributed to the very great success of the forums and to the community spirit there. We plan to create new community features and services in the future so please watch this space for developments in this area. In the meantime if you have any questions then please email:

Currently Being Moderated

Ana Cristina Furtado Rebelo – University of the Azores, Department of Biology

 

NHM Earth Sciences Seminar Room (Basement, WEB 05, formerly Mineralogy Seminar Room)

 

20th May - 4.00 pm

 

 

Rhodoliths are the response of Coralline algae to unstable substrates; their calcified structures preserve well and may, after death, be incorporated into sediments, providing insights into geological processes. Despite being widely distributed, studies on the distribution and ecology of extant and fossil rhodoliths are few and, as a consequence, rhodoliths are still poorly understood.

 

The ongoing research in the Azores will provide more insight on why those islands are so different from others in Macaronesia with respect to rhodolith deposits in the geological record and the general lack of coastal rhodolith deposits today.

 

The comparison of type material in the Botany and Palaeobotany collections of the NHM with material from the Azores collection is expected to yield information on the Azorean rhodolith taxonomy identification, and will provide a model for palaeobiogeographic distribution. Such task needs the knowledge of the most advanced curatorial techniques and a profound taxonomic understanding of this specific algae group.
