Sea-urchin. Innovations

"Antarctic benthic communities below anchor ice and ice scour are subjected to intense biotic interactions, and this has propitiated the development of chemicals to avoid predation, competition, and/or fouling avoidance. In particular, Sterechinus neumayeri, a common eurybathic sympatric sea urchin species, can have a negative effect on early recruitment of benthic organisms through grazing. An adaptive response of these co-existing benthic animals may consist in displaying cytotoxic activities, poorly investigated so far in Antarctic ecosystems, in order to prevent the settlement of embryos and larvae of this sea urchin on them or near and, consequently, to decrease its grazing pressure. Cytotoxic activities of Antarctic benthic organisms, mainly from the deep waters of the poorly surveyed area of the eastern Weddell Sea, were assessed against embryos and sperm of the sea urchin S. neumayeri. Open access to the scientific literature means the removal of barriers (including price barriers) from accessing scholarly work. There are two parallel “roads” towards open access: Open Access articles and self-archiving. Open Access articles are immediately, freely available on their Web site, a model mostly funded by charges paid by the author (usually through a research grant). The alternative for a researcher is “self-archiving” (i.e., to publish in a traditional journal, where only subscribers have immediate access, but to make the article available on their personal and/or institutional Web sites (including so-called repositories or archives)), which is a practice allowed by many scholarly journals.
