Costs of Exploitation: A Matter of Timing?

Jessica Barker and Judith Bronstein propose that considering the timing of exploitation relative to cooperation can provide insight into two debated features of mutualism: the costs of being exploited and the resulting mechanisms to control exploitation.

Slow Diversification of Mesozoic Tetrapods

A large-scale examination of the fossil record by Roger Benson, Graeme Lloyd and colleagues reveals slow diversification rates in tetrapods across 190 million years, followed by an abrupt 4-fold increase in species richness after the end-Cretaceous mass extinction event.

Good Amyloid, Bad Amyloid—What’s the Difference?

Although amyloids are usually associated with abnormality and disease, some are functional. Rubén Hervás, Liying Li, Kausik Si, Mariano Carrión-Vázquez and co-authors show that in the case of the functional amyloid Orb2, needed for memory consolidation in flies, key features of the kinetics of amyloid formation may underlie this crucial difference.

Leaf City: Microbial Hub Taxa in the Phyllosphere

A study by Matthew Agler, Eric Kemen and colleagues reveals that microbial interactions between kingdoms are responsible for significant microbiome variation on the surface of plants. Highly connected microbes are most important, amplifying abiotic and host factors to cause large perturbations in the structure of microbial communities.

Good News from Animal Selfies?

Inaugural results from a pan-tropical camera trap network, analyzed by Lydia Beaudrot, Jorge Ahumada, Sandy Andelman and co-authors, suggest that, in contrast to other reports, tropical forest protected areas maintain their biodiversity of large and medium ground-dwelling mammals and birds. Read the Synopsis and Biologue post.
