Antarctic Starfish (Echinodermata, Asteroidea) from the ANDEEP3 expedition
This dataset includes information on sea stars collected during the ANDEEP3 expedition, which took place in 2005. The expedition focused on deep-sea stations in the Powell Basin and Weddell Sea.Sea stars were collected using an Agassiz trawl (3m, mesh-size 500µm), deployed in 16 stations during the ANTXXII/3 (ANDEEP3, PS72) expedition of the RV Polarstern. Sampling depth ranged from 1047 to 493...
متن کاملJ. Lawrence Pool Symposium
Received, November 25, 2007. Accepted, June 4, 2008. Recent technological advances and collaborative efforts between neurosurgeons and neurointensivists have reduced the overall aneurysmal subarachnoid hemorrhage (SAH) fatality rate from 50% to nearly 20% (Table 1) (96, 115). Despite this encouraging trend, there continues to be room for improvement in the outlook for poorgrade SAH. While goodg...
متن کاملTrophic ecology of deep-sea Asteroidea (Echinodermata) from eastern Canada
Asteroids (sea stars) can be important predators in benthic communities and are often present in ecologically important and vulnerable deep-sea coral and sponge habitats. However, explicit studies on the trophic ecology of deep-sea asteroids are rare. We investigated the diets of seven species of deep-sea asteroid from the bathyal zone of Newfoundland and Labrador, eastern Canada. A multifacete...
متن کاملTiming of fission in the starfish Allostichaster capensis (Echinodermata: Asteroidea) in laboratory.
Timing of fission in the fissiparous starfish Allostichaster capensis under laboratory conditions is described. A. capensis generally splits across the disc along the fission plane during the spring, and then each half regenerates the missing arms during the rest of the year. The fission process can last eight hours. The healing process starts immediately after fission. A. capensis has impressi...
متن کاملEcology and evolution on the banks of the St Lawrence.
The population biologist John Harper (1967) wrote that ‘the theory of evolution by natural selection is an ecological theory, founded on ecological observation by perhaps the greatest of all ecologists’. More than 40 yr since this observation, it is surprising that the professional societies devoted to the study of ecology and evolution still remain largely distinct (for example, consider the S...
