Animals rarely solve problems spontaneously. Some bird species, however, can immediately find a solution to the string-pulling problem. They are able to rapidly gain access to food hung on the end of a long string by repeatedly pulling and then stepping on the string. It is currently unclear whether these spontaneous solutions are produced by insight or by a perceptual-motor feedback loop. Here...

The Pacific margin of East Antarctica records a long tectonic history of crustal growth and breakup, culminating in the early Paleozoic Ross Orogeny associated with Gondwanaland amalgamation. Periods of older tectonism have been proposed (e.g. Precambrian Nimrod and Beardmore Orogenies), but the veracity of these events is difficult to document because of poor petrologic preservation, geochrono...

Late to post-Caledonian, Devonian extension remains unresolved in the SW Barents Sea, despite considerable knowledge from onshore Norway, East Greenland and Svalbard. We analyse intrabasement seismic facies high-resolution 3D reprocessed 2D data investigate evidence for Caledonian deformation post-Caledonian detachment faulting central Sea. These results are compared published potential field m...

The New Caledonian endemic weevil genus Hellerenius is revised, with three new species described: H. monteithi, H. plumipes, and H. tibialis. A new genus Archellerenius is proposed for Archellerenius giustoi n. sp. Diagnoses, a key and distribution maps are provided for all species. Association of Hellerenius with the plant genus Hedycarya (Monimiaceae) is confirned.
