In the early fall of 1996, a bloom of the toxic dinoflagellate Alexandrium catenella occurred in a fjord in the southern part of Chile that resulted in very high levels of paralytic shellfish poisoning (PSP) toxicity (up ...

For the first time we document several species of micro-mollusks in the Galapagos inhabiting lichens and bryophytes, possibly using them as part of their diet. Eight species of mucro-mollusks were found as a by-cath among ...

Predatory strategies used by carnivorous gastropods may change during their ontogeny. Inmuricid gastropods attack mechanisms include an accessory boring organ (ABO), radula, labraltooth and/or pedal muscle. However, these ...

Active predators obtain energy and nutrients from prey through complex processes in which the energy gained must exceed the energy invested in finding and ingesting the prey. In addition, the amount of energy available ...

The first record of a Chilean gastropod of the Late Oligocene of Argentina is described. The specimens show a typical general morphology and a characteristic nepionic sculpture of Chiliborus (Mollusca: Gastropoda), being ...

Functional diversity based on species traits is a powerful tool to investigate how changes in species richness and composition affect ecosystem functioning. However, studies aimed at understanding changes in functional ...
