Editorial Cite this article: Walther BD, Munguia P, Fuiman LA. 2015 Frontiers in marine movement ecology: mechanisms and consequences of migration and dispersal in marine habitats. Dispersal and migration are important ecological processes that influence rates of propagule exchange, colonization, extinction and speciation for a wide array of taxa in terrestrial and aquatic systems. The role of ...

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...

The widespread occurrence and accumulation of plastic waste in the environment have become a growing global concern over the past decade. Although some marine organisms have been shown to ingest plastic, few studies have investigated the ecological effects of plastic waste on animals. Here we show that exposure to environmentally relevant concentrations of microplastic polystyrene particles (90...

Understanding the drivers (internal and external) that determine the productivity of marine ecosystems is challenging. For example, the correct estimate of recruitment is essential to estimate fish stock abundance. In this Theme Section, 5 papers explore the effect of fishing and climate on population structure across sub-Arctic ecosystems. The studies focus on how temperatureand fishing-induce...

I N T E R N A T I O N A L E X P E R I E N C E Around the world many fisheries have collapsed, including some in Australia. Consequently marine fisheries are under increasing pressure to adopt more precautionary management approaches. Although Australia’s fisheries are generally in good shape—few are overfished—many are fully exploited. Overseas experience tells us that even the best fisheries m...

This contribution, which serves as introduction to a special issue of Ecological Modelling briefly discusses some of the implication for research of the widely heard calls for a transition toward ecosystem-based management of fisheries. Notably, the case is made that the research required for this transition does not need, in order to be useful at all, to explicitly address the full complexity ...

At the recent Benguela 86 Symposium one of the participants decided to make a very strange recantation. There was sufficient evidence, in his view, to suggest that there was no reason to do the causal research in fisheries-related marine ecology, once the conventional average fishery information or parameter estimates were available. You could be right more often using average expectations in y...
