Populations of most marine organisms are connected by the dispersal of larval stages, with profound implications for marine conservation. Because of the extreme effort needed to empirically measure larval exchange, multispecies conservation efforts must estimate connectivity by extrapolation using taxonomy, adult distribution, life history, behavior, or phenology. Using a 6-year record of conne...

Little is known about how fishes and other non-calcifying marine organisms will respond to the increased levels of dissolved CO(2) and reduced sea water pH that are predicted to occur over the coming century. We reared eggs and larvae of the orange clownfish, Amphiprion percula, in sea water simulating a range of ocean acidification scenarios for the next 50-100 years (current day, 550, 750 and...

Very few traditional foods that are consumed have been subjected to systematic toxicological and nutritional assessment, yet because of their long history and customary preparation and use and absence of evidence of harm, they are generally regarded as safe to eat. This 'history of safe use' of traditional foods forms the benchmark for the comparative safety assessment of novel foods, and of fo...

The wide range of plant and animal species that live on the planet – referred to as biodiversity – is now being threatened by intensive agriculture. A growing human population, however, also entails growing needs, which, in turn, requires current agricultural practices to maximize the use of available land while minimizing damage to the environment and biodiversity. Genetically modified (GM) cr...

Plastic debris at the micro-, and potentially also the nano-scale, are widespread in the environment. Microplastics have accumulated in oceans and sediments worldwide in recent years, with maximum concentrations reaching 100 000 particles m(3). Due to their small size, microplastics may be ingested by low trophic fauna, with uncertain consequences for the health of the organism. This review foc...

This well-known book has been thoroughly revised and brought up-to-date; it is now in its eighth edition. The writers have succeeded in producing a manual which is not merely a collection of facts but is a wellbalanced and readable book in which the student and practitioner will find all that is of importance in the science and practice of bacteriology. One says bacteriology, because, although ...
