Data from: Diet quality in a wild grazer declines under the threat of an ambush predator

Predators influence prey populations not only through predation itself, but also indirectly through prompting changes in prey behaviour. The behavioural adjustments of prey to predation risk may carry nutritional costs, but this has seldom been studied in the wild in large mammals. Here, we studied the effects of an ambush predator, the African lion (Panthera leo), on the diet quality of plains zebras (Equus quagga) in Hwange National Park, Zimbabwe. We combined information on movements...

Data from: Metagenomic chromosome conformation capture (meta3C) unveils the diversity of chromosome organization in microorganisms

Martial Marbouty, Axel Cournac, Jean-Francois Flot, Herve Marie-Nelly, Julien Mozziconacci & Romain Koszul
Genomic analyses of microbial populations in their natural environment remain limited by the difficulty to assemble full genomes of individual species. Consequently, the chromosome organization of microorganisms has been investigated in a few model species, but the extent to which the features described can be generalized to other taxa remains unknown. Using controlled mixes of bacterial and yeast species, we developed meta3C, a metagenomic chromosome conformation capture approach that allows characterizing individual genomes and their...

Data from: Ecology of information: social transmission dynamics within groups of non-social insects

Marine Battesti, Cristian Pasquaretta, Celine Moreno, Serafino Teseo, Dominique Joly, Elizabeth Klensch, Odile Petit, Cedric Sueur & Frederic Mery
While many studies focus on how animals use public information, the dynamics of information spread and maintenance within groups, i.e. the ‘ecology of information’, have received little attention. Here we use fruitflies trained to lay eggs on specific substrates to implement information into groups containing both trained and untrained individuals. We quantify inter-individual interactions and then measure the spread of oviposition preference with behavioural tests. Untrained individuals increase their interactive approaches in the presence of...
