In line with global targets agreed under the Convention on Biological Diversity, the number of marine protected areas (MPAs) is increasing rapidly, yet socio-economic benefits generated by MPAs remain difficult to predict and under debate. MPAs often fail to reach their full potential as a consequence of factors such as illegal harvesting, regulations that(More)
While large mass mortality events (MMEs) are well known for toothed whales, they have been rare in baleen whales due to their less gregarious behaviour. Although in most cases the cause of mortality has not been conclusively identified, some baleen whale mortality events have been linked to bio-oceanographic conditions, such as harmful algal blooms (HABs).(More)
During two scuba-diving expeditions in 2005 and 2006, stylasterids were documented and sampled from fjords and channels in the Central Patagonian Zone, Chile. At 15 of a total of 33 sampling sites we found colonies of Errina antarctica. We discuss the observed distribution patterns and the variability of colony shapes. In some regions we found E. antarctica(More)
The hydrocoral Errina antarctica is described around southern South America (south of 50 S; Fig. 1) and along the Scotia Arc down to 771 m (Cairns 1983). In Chile, we found E. antarctica in diving depths as far north as 43 25¢S. It has been identified as key structural species creating important habitats for a multitude of organisms (Häussermann and(More)
Mass spawning is well documented for many species of gamete-releasing scleractinians and for some species of actiniarians, but little information is available for corallimorpharians. Here, we report in situ observations of broadcast spawning of a corallimorpharian anemone. The benthos of Chilean Patagonian fjords is dominated by filter feeders and, below(More)

Rhodolith or maërl are the most common terms used for free living coralline red algae which live and produce sediments (Nelson 2009). They are common in the North Atlantic, Mediterranean, tropical West Atlantic, Gulf of California, Southern Japan, Western Australia and New Zealand (Foster 2001). Rhodolith beds reach the deepest section of the euphotic zone,(More)
