Marine biology

Marine biology is the study of life in the oceans and brackish waters, which ranges from archaea and bacteria to marine mammals, and includes organisms such as corals that affect the shape of the seafloor. This may also include human modifications to ocean biology, such as fisheries or the effects of overfishing.

    Rapid evolution of morphological variations is shown to be linked to positions of coral reef fishes at trophic-web extremes. This finding suggests that current fishing practices on coral reefs that target top predators and seaweed-grazing fishes may undermine the potential for future species diversification.

    Biological communities beneath Antarctic ice shelves remain a mystery, hampering assessment of ecosystem development after ice-shelf collapse. Here we highlight major gaps in understanding of the patterns and processes in these areas, and suggest effective ways to study the ecological impacts of ice-shelf loss under climate change.

    In many fish stocks, older and larger fish are found in deeper waters compared with younger individuals. This concept of ontogenetic deepening is now proposed to be a result of harvesting rather than a natural phenomenon.

    Predators have important roles in structuring ecosystems, yet many are critically endangered and their reputation among non-scientists is decidedly mixed.

    The increasing acidity of our seas is a threat to marine life that for many species may be impossible to overcome.
