Potential chemical defenses of Antarctic benthic organisms against marine bacteria

Chemical Interactions in Antarctic Marine Benthic Ecosystems

The Distribution of Antarctic Marine Benthic Communities

The Polar Frontal Zone, although predominantly a surface feature, forms a natural northernmost boundary for defining the Southern Ocean, and relatively few benthic organisms have distributions which cross this boundary. Many Antarctic benthic plants and animals have circumpolar distributions but some broad geographical subdivisions may be made. Detailed studies of community distribution are few...

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. 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...

On the origin of Antarctic marine benthic community structure.

Environmental conditions fostering marine communities around Antarctica differ fundamentally from those in the rest of the world's oceans, particularly in terms of pronounced climatic fluctuations and extreme cold. Here, we argue that the rarity of pelagic larval stages in Antarctic marine benthic invertebrate species is a consequence of evolutionary temperature adaptation and that this has gre...
