Humpback whales (Megaptera novaeangliae), a mysticete with a cosmopolitan distribution, demonstrate
marked behavioural plasticity. Recent studies show evidence of social learning in the transmission of specific
population level traits ranging from complex singing to stereotyped prey capturing behaviour. Humpback
whales have been observed to employ group foraging techniques, however details...

The choice of what to eat is political, and food systems shape and are shaped by political and economic power. During the last several hundred years, agricultural and food power has been consolidated to an unprecedented degree, and this consolidation continues today. This paper will describe this process as “Governing...
"This document is an interim report by the Heritage Program, submitted to the Oregon Parks and Recreation Branch. It summarizes: 1) the data collected on natural areas in private, county and municipal ownership throughout the state; 2) the techniques used to collect this data; 3) a system for storing, analyzing...
We live in a world today where it doesn’t come as a surprise to hear about another girl being roofied at a college party, nor is it shocking to find out about how your friend was sexually harassed by an older man at work. Women are taught how to avoid...

Quantum Darwinism recognizes the role of the environment as a communication channel: Decoherence can selectively amplify information about the pointer states of a system of interest (preventing access to complementary information about their superpositions) and can make records of this information accessible to many observers. This redundancy explains the emergence...

Chemical and structural heterogeneity and the resulting interaction of coexisting phases can lead
to extraordinary behaviours in oxides, as observed in piezoelectric materials at morphotropic phase boundaries and relaxor ferroelectrics. However, such phenomena are rare in metallic alloys. Here we show that, by tuning the presence of structural heterogeneity in...
Losses of corals worldwide emphasize the need to understand what drives reef decline. Stressors such as overfishing and nutrient pollution may reduce resilience of coral reefs by increasing coral–algal competition and reducing coral recruitment, growth and survivorship. Such effects may themselves develop via several mechanisms, including disruption of coral microbiomes....
