Advances in Marine Biology : Advances Chepalopod Science Biology, Ecology, Cultivations and Fisheries 61
The idea of this special contribution reviewing the latest advances in sponge
science was conceived during the World Sponge Conference held in
Girona (Spain) in September 2010. Dr. Michael Lesser, editor of the
Advances in Marine Biology book series, first suggested the production of
a sponge-dedicated monograph. As organizers of the conference, we realized
that the amount of information available had increased exponentially
in recent years. As this overwhelming new information is scattered over an
enormous volume of scientific papers published in journals of very different
disciplines, we agreed that a thorough compilation and comprehensive
review would be appropriate and useful. The monograph could convey
the latest advances in sponge science to sponge specialists besides providing a
comprehensive overview to a wider audience with interest in invertebrate
biology, marine ecology, molecular ecology, or phylogeny among others.
This contribution is timely because we lack reviews in some topics, while in
other aspects, reviews were either too old or have become outdated because
significant progress has been achieved in the past years. So we took the bait
and you have in your hands the results of our efforts to sum up the most
relevant and up-to-date scientific literature on the Phylum Porifera.
Sponges are extraordinary animals. With over 8000 extant described
species, these organisms are major players in many scientific disciplines.
Sponges have relevant roles in shaping the ecological functioning of many
marine benthic communities, hold a strategic position for understanding the
evolutionary origin of animals, and produce a great variety of secondary
metabolites and skeletal structures that have made them preferred targets in
biotechnological research. This contribution, split in two thematic volumes,
comprises a representative selection of the most active fields of sponge
research. Even if not exhaustive, this multiauthor blend of visions offers a
wide portrait of the state of the art in sponge science. We have intended the
volumes to highlight recent developments in multiple scientific fields, while
identifying current limitations and knowledge gaps and delineating challenges
and foreseeable future directions.
More specifically, the contributions include an overview of the titanic
research work performed on taxonomy and ecology of Caribbean sponges
over the past decades. The amazing array of ecological interactions in which
sponges engage, with special emphasis on the diversity and functionality of
their associated microbiomes, are dealt with in other chapters. The revolution
that new molecular tools have represented in ecological studies is also
covered in a dedicated chapter. The role of sponges in biogeochemical
nutrient cycling is reviewed for the first time. The cell and molecular
biology of sponges is a rocketing field, which gets its most recent advances
and insights discussed from a modern perspective. Some chapters deal with
sponge systematics and phylogeny, which are being hotly debated from
several points of view, including a variety of hypotheses to interpret the
relationships between sponge groups, other basal invertebrates, and early
bilaterian animals. The rich chemical warfare featured by sponges, which
has made this group a prolific source of new active natural products, has also
been addressed, as well as the sponge machinery for processing and accumulating
silica and its implications in tissue engineering. Although some of
these chapters provide a good balance between basic and applied research,
more biotechnologically oriented issues related to the culture of sponges,
sponge cells, or symbionts for the production of chemicals have also found
its place in the monograph. The chapters have been organized in two
volumes: one covering the topics of phylogeny, systematics, and ecology,
and the other dealing with physiology, chemical and microbial diversity,
and biotechnology.
