Data from: A metacognitive illusion in monkeys

Stephen Ferrigno, Nate Kornell & Jessica F. Cantlon
Like humans, monkeys can make accurate judgements about their own memory by reporting their confidence during cognitive tasks. Some have suggested that animals use associative learning to make accurate confidence judgements, while others have suggested animals directly access and estimate the strength of their memories. Here we test a third, non-exclusive possibility: perhaps monkeys, like humans, base metacognitive inferences on heuristic cues. Humans are known to use cues like perceptual fluency (e.g. how easy something...

Data from: Mechanisms of aggregation in an ant-tended treehopper: attraction to mutualists is balanced by conspecific competition

Manuel A. Morales & Andrew G. Zink
Understanding the spatial structure of populations and communities has been a dominant focus of ecological research, and spatial structure is increasingly seen as critical for understanding population dynamics. Habitat (or host) preference is a proximate mechanism that can generate aggregation or overdispersion, lending insight into the ultimate consequences of observed spatial distributions. Publilia concava is a univoltine phloem-feeding insect that forms mutualistic associations with ants, which consume honeydew and protect treehoppers from predation. Treehopper adults...

Data from: Tsunami-driven rafting: transoceanic species dispersal and implications for marine biogeography

James T. Carlton, John W. Chapman, Jonathan B. Geller, Jessica A. Miller, Deborah A. Carlton, Megan I. McCuller, Nancy C. Treneman, Brian P. Steves & Gregory M. Ruiz
The 2011 East Japan earthquake generated a massive tsunami that launched an extraordinary transoceanic biological rafting event with no known historical precedent. We document 289 living Japanese coastal marine species from 16 phyla transported over 6 years on objects that traveled thousands of kilometers across the Pacific Ocean to the shores of North America and Hawai‘i. Most of this dispersal occurred on nonbiodegradable objects, resulting in the longest documented transoceanic survival and dispersal of coastal...
