Effects of ocean acidification over the life history of the barnacle Amphibalanus amphitrite
Increased levels of atmospheric CO2 are anticipated to cause decreased seawater pH. Despite the fact that calcified marine invertebrates are particularly susceptible to acidification, bar- naclesExpand

Ecology of Antarctic Marine Sponges: An Overview1
Abstract Sponges are important components of marine benthic communities of Antarctica. Numbers of species are high, within the lower range for tropical latitudes, similar to those in the Arctic, andExpand

Life strategy, ecophysiology and ecology of seaweeds in polar waters
Polar seaweeds are strongly adapted to the low temperatures of their environment, Antarctic species more strongly than Arctic species due to the longer cold water history of the Antarctic region. ByExpand

West Antarctic Peninsula: An Ice-Dependent Coastal Marine Ecosystem in Transition
The extent, duration, and seasonality of sea ice and glacial discharge strongly influence Antarctic marine ecosystems. Most organisms' life cycles in this region are attuned to ice seasonality. TheExpand

Dispersal in Kelps: Factors Affecting Spore Swimming and Competency
The distance over which propagules can successfully colonize new sites de- pends on processes that increase the time they remain competent while being dispersed. As do feeding larvae, algal sporesExpand

PHOTOSYNTHETIC PHYSIOLOGY AND CHEMICAL COMPOSITION OF SPORES OF THE KELPS MACROCYSTIS PYRIFERA, NEREOCYSTIS LUETKEANA, LAMINARIA FARLOWII, AND PTERYGOPHORA CALIFORNICA (PHAEOPHYCEAE) 1
Recently released spores of the kelps Macrocystis pyrifera (L.) C. Ag., Nereocystis luetkeana (Mert.) Post. and Rupr., Laminaria farlowii Setch., and Pterygophora californica Rupr. had differentExpand

Overview 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. InExpand

Palatability and chemical anti-predatory defenses in common ascidians from the Antarctic Peninsula
Palatability of outer tissues of a suite (12 species) of Antarctic ascidians was evaluated using omnivorous fish and sea star predators. Tissues of 100% of those tested were unpalatable to fish,Expand

Feeding rates of common Antarctic gammarid amphipods on ecologically important sympatric macroalgae
Single species feeding trials employing both fresh algal tissues and alginate food pellets containing dried finely ground algal tissues were conducted to examine the relative palatability ofExpand

Patterns of gammaridean amphipod abundance and species composition associated with dominant subtidal macroalgae from the western Antarctic Peninsula
The communities of gammaridean amphipods associated with eight dominant macroalgal species were examined near Palmer Station, Western Antarctic Peninsula. A total of 78,415 individuals belonging toExpand
