Vocal copying of individually distinctive signature whistles in bottlenose dolphins [PDF]
, 2013 Vocal learning is relatively common in birds but less so in mammals. Sexual selection and individual or group recognition have been identified as major forces in its evolution.

Maximizing eDNA detections of rare marine organisms: A case study of a delphinid species
Methods in Ecology and Evolution, EarlyView.Abstract Environmental DNA (eDNA) is an emerging tool for surveying marine organisms. Advances in molecular assay designs and bioinformatic methods provide new opportunities for detecting rare species; however, overcoming methodological challenges of rare species detection remains an important obstacle for the widespread deployment of eDNA methods for ...

As‐Rigid‐As‐Possible Regularization for Implicit Surfaces
Computer Graphics Forum, EarlyView.Abstract Implicit surface representations have regained popularity because of their use in machine learning. A common component in optimization is regularization, penalizing the deviation of the surface from its original shape. The popular as‐rigid‐as‐possible (Arap) energy strikes a good compromise between realistic deformation behavior and efficient ...

Acoustic behaviour of Risso's dolphins, Grampus griseus, in the Canary Islands, Spain [PDF]
, 2013 The Risso's dolphin (Grampus griseus) is a poorly studied species, particularly with respect to its acoustic behaviour. The little we know about Risso's dolphin acoustics shows that they are an interesting case study given that they combine acoustic ...
