Hunting in Bioluminescent Light: Vision in the Nocturnal Box Jellyfish Copula sivickisi
Cubomedusae all have a similar set of six eyes on each of their four rhopalia. Still, there is a great variation in activity patterns with some species being strictly day active while others are strictly night active. Here we have examined the visual ecology of the medusa of the night active Copula sivickisi from Okinawa using optics, morphology, electrophysiology, and behavioral experiments. W...
متن کاملJELLYFISH BLOOMS Jellyfish in ecosystems, online databases, and ecosystem models
There are indications that pelagic cnidarians and ctenophores (‘jellyfish’) have increased in abundance throughout the world, or that outbreaks are more frequent, although much uncertainty surrounds the issue, due to the scarcity of reliable baseline data. Numerous hypotheses have been proposed for the individual increases or outbreaks that are better documented, but direct experimental or mani...
متن کاملJellyfish Mesogloea Collagen
The mesogloea collagen of a primitive animal, the jellyfish Stomolophus nomurai, belonging to the class Scyphozoa in the Coelenterata, was studied with respect to its chain structure. Most of the mesogloea collagen was solubilized by limited digestion with pepsin and isolated by selective precipitation at 0.9 M NaCl in 0.5 M acetic acid. Upon denaturation, the pepsinsolubilized collagen produce...

On day 19, vemurafenib therapy was discontinued, and within 7days thereafter, the feverhad improved, and theelectrolyte profile had normalized. Tumor assessment showed a major tumoral response. On day 29, vemurafenib treatment was restarted at half dose, leading within 21 days (day 50) to a relap...
متن کاملMutualistic hunting
The cooperative acquisition, defense and distribution of meat are common problems that must be solved by social hunters. These were also problems faced by any of our hominid ancestors that may have hunted large game in our evolutionary past. Much of the last 40 years of research in evolutionary ecology has tried to understand such cooperative behavior. The classic Prisoner's Dilemma game theory...
