High-silica rhyolites (HSRs) are rhyolites containing > 75 wt% SiO 2 on an anhydrous basis. In this contribution we have studied four Icelandic isolated occurrences away from central volcanoes (i.e., Icelandic volcanoes with a well-developed volcanic plumbing system): three in active rift zones (Mælifell, Ketilhyrnur and Prestahnúkur) and one in a flank/off-rift zone (Sultarfell). With no established central volcano, in which...

The larvae or phyllosomes of many species of spiny lobsters (Palinuridae) are known to complete their development in offshore oceanic waters. Phyllosomes metamorphose to non‐feeding, nektonic post‐larvae or pueruli, which move into shallow coastal waters where they settle to become benthic dwelling juveniles. There is growing evidence that the movement of pueruli is directed toward the coast rather than a process of random dis...
