Increased tourist activity in coastal regions demands management strategies to reduce impacts on rocky shores. The highly populated coastal areas in southeastern Brazil are an example of degradation caused by development of industry and tourism. Among different shore impacts, trampling has been intensively studied, and may represent a significant source of stress for intertidal fauna. A randomi...

Ecosystems can undergo dramatic shifts from one stable state to another. While indicators of such shifts are well known, experimental tests are few and far between. A new study on rocky shore ecosystems now offers a test of warning indicators.

A new study on a parasitic barnacle that lives on a deep sea shark found that its closest living relatives are rocky shore barnacles. The findings provide insight into barnacle phylogeny and raise new questions about the evolution of parasitism.

The design and analysis of manipulative experiments is a key skill for undergraduate ecologists to learn. Despite this, students rarely conduct a true manipulative experiment with appropriate control treatments in the field, because of practical constraints such as time. Meaningful ecological experiments typically require months to obtain results, as well as constant maintenance and attention; ...

Sandy beaches in some areas of the São Sebastião Channel in southeastern Brazil have unremittingly undergone a variety of impacts, including the deposition of rock fragments in the intertidal region. Consequently, these environments support a rich fauna comprising both sandy beach and rocky shore organisms. Two rocky shore gastropods, Tegula viridula and Morula nodulosa, are particularly abunda...

The lipid class composition in juveniles of the mussel Mytilus galloprovincialis of rocky shore and subtidal origin were compared after transfer to a subtidal environment in the Ria de Arousa (northwest Spain). The experiment was conducted between November 27, 1995 and July 3, 1996. In addition to mussel origin, the influence of the different environmental parameters on the changes in lipid cla...
