Fish in Lévy-flight foraging
Lévy flights are a theoretical construct that has attracted wide interdisciplinary interest. Empirical evidence shows that the principle applies to the foraging of marine predators.

Population diversity and the portfolio effect in an exploited species
The value of having a diversity of species within an ecosystem is well appreciated: species-rich communities are thought to produce more stable ecosystem services. But population diversity within a species is important too. Here, the effects of diversity in population and life history in a heavily exploited Alaskan salmon species are quantified. The results show that population diversity increases the resilience of this ecosystem, and hence the value of salmon fisheries.

Ecological interactions are evolutionarily conserved across the entire tree of life
It is expected that closely related organisms are more likely to show similar ecological interactions than less related ones. But this has been tested only for certain types of interaction, and in a restricted set of taxa. Now interaction networks have been constructed for 116 different clades of related organisms, across the entire tree of life, and including all types of interaction. The results reveal significant conservatism across the board, including both specialist and generalist species.

A Late Cretaceous ceratopsian dinosaur from Europe with Asian affinities
Ceratopsians — horned dinosaurs — were distinctive features of the fauna of the Cretaceous period in East Asia and western North America. There have been hints that they might also have occurred elsewhere, but this has not been definitive, until now. The discovery of a ceratopsian, Ajkaceratops kozmai, from what is now Hungary shows that Late Cretaceous biogeography still has surprises in store.

Small mammal diversity loss in response to late-Pleistocene climatic change
Many large mammals became extinct worldwide at the end of the Pleistocene epoch, around 12,000 years ago. Here, it is shown that smaller mammals, which often provide much more comprehensive fossil records than large mammals, were much less likely to respond to the Pleistocene–Holocene transition by becoming extinct. Instead, diversity and evenness suffered, so that less abundant species became rarer, with more generalist 'weedy' species becoming more common.

Q&A: Sylvia Earle on protecting our seas
Oceanographer and underwater explorer Sylvia Earle served as chief scientist of the US National Oceanic and Atmospheric Administration during 1990–92, and is a US national committee member of the Census of Marine Life, due to conclude this October. Earle advised on Disney's newly released cut of the documentary film Oceans; here she explains why films are important for raising awareness of the state of our seas.
