Ecology and energetics of two Antarctic sponges.
Retention efficiencies, pumping and respiration rates of the two Antarctic sponge species Mycale acerata and Isodictya kerguelensis from Potter Cove, King George Island, were measured. None of the species reached a 100% retention efficiency at any given particle size. This is probably due to the sediment-laden environment in which the animals were dwelling. A less efficient retention decreases ...
متن کاملCultivable psychrotolerant yeasts associated with Antarctic marine sponges.
Unlike filamentous fungi and bacteria, very little is known about cultivable yeasts associated with marine sponges, especially those from Antarctic seas. During an expedition to King George Island, in the Antarctica, samples of 11 marine sponges were collected by scuba-diving. From these sponges, 20 psychrotolerant yeast isolates were obtained. Phylogenetic analyses of D1/D2 and ITS rRNA gene s...
متن کاملOverview of the chemical ecology of benthic marine invertebrates along the western Antarctic peninsula.
Thirteen years ago in a review that appeared in the American Zoologist, we presented the first survey of the chemical and ecological bioactivity of Antarctic shallow-water marine invertebrates. In essence, we reported that despite theoretical predictions to the contrary the incidence of chemical defenses among sessile and sluggish Antarctic marine invertebrates was widespread. Since that time w...
متن کاملAntimicrobial Effects of Some Persian Gulf Marine Sponges
Background: We investigated in vitro antimicrobial activity of five marine sponge species collected from Kish Island in the Persian Gulf: Fascaplysinopsis reticulata, Callyspongia clavatus, Callyspongia siphonella, Niphates furcata, and Pseudosuberites clavatus against gram positive bacteria, gram negative bacteria, fungi and yeasts. Materials and Methods: Sponage extracts were prepared by two ...
متن کاملBiological Activities of Ethanolic Extracts from Deep-Sea Antarctic Marine Sponges
We report on the screening of ethanolic extracts from 33 deep-sea Antarctic marine sponges for different biological activities. We monitored hemolysis, inhibition of acetylcholinesterase, cytotoxicity towards normal and transformed cells and growth inhibition of laboratory, commensal and clinically and ecologically relevant bacteria. The most prominent activities were associated with the extrac...
