Systematics is nowadays facing new challenges with the introduction of new concepts and
new techniques. Compared to most other phyla, phylogenetic relationships among sponges …

Much of what we know about speciation comes from detailed studies of well‐known model
systems. Although there have been several important syntheses on speciation, few (if any) …

Covering: the literature from the first reported isolation of a pyrroloiminoquinone metabolite
from a marine sponge in 1986 up to October 1, 2004. This review presents the structure …

Alkaloids, such as lamellarins1 and manzamines, 2 with complex structures and promising
biological activities produced by marine plants, invertebrates and microbes have greatly …

Over the past several decades molecular tools have shown an enormous potential to aid in
the clarification of species boundaries in the marine realm, particularly in morphologically …

Nymphon australe Hodgson 1902 is the most abundant species of sea spiders in the
Southern Ocean. The species is recognised as highly morphologically variable, circumpolar …

In the last decade, greater than expected levels of genetic structure have been reported for
many marine taxa with high dispersal capabilities. Although little‐studied to date, it is …

In addition to their pharmaceutical applications, sponges are an important source of
compounds that are used to elucidate classification patterns and phylogenetic relationships …

The sponge genus Latrunculia is a prolific source of discorhabdin type pyrroloiminoquinone
alkaloids. In the continuation of our research interest into this genus, we studied the Antarctic …

Schindleria (Gobioidei, Schindleriidae), believed to include one of the smallest and
youngest reproducing vertebrates, is broadly distributed in the Indo-Pacific Oceans …
