Cultural transmission of animal tool use driven by trade-offs: insights from sponge-using dolphins
Although tool use offers obvious benefits to the user, the role of costs in the spread of tool use has received scant attention. Sponge tool use is a foraging technique restricted to a small subpopulation of bottlenose dolphins (Tursiops aduncus) in ...

Comparison of antibacterial activities of Ircinia mutans extracts in two different seasons from Kish Island, Persian Gulf, Iran [PDF]
Sponges, which constitute the phylum Porifera, are the most primitive of the multicellular animals, among all marine organisms screened. Marine sponges produce the largest number of structurally diversified natural products. In this study we investigated

Polyprenyl derivatives from the sponge Ircinia spinosula
Abstract Unsubstituted prenylated benzoquinones, a novel group of terpenoid quinones, the corresponding quinols, together with the hydroxylated 2-octaprenyl-quinol (VII) have been identified in the marine sponge Ircinia spinosula. From the same sponge we have also isolated the prenylated furan derivatives XI, XII and XIII, named furospinosulin-1, -2 ...
