Initiation and spread of escape waves within animal groups [PDF]
, 2015 The exceptional reactivity of animal collectives to predatory attacks is thought to be due to rapid, but local, transfer of information between group members. These groups turn together in unison and produce escape waves.

Patterns of distribution and abundance of larval phosichthyidae (actinopterygii, stomiiformes) in southeastern Brazilian waters [PDF]
, 2011 Horizontal and vertical distribution patterns and abundance of larval phosichthyids were investigated from oblique and depth-stratified towns off Southeastern brazilian waters, from São Tomé cape (41ºW.; 22ºS.) to São Sebastião island (45ºW.; 24ºS.). The

, 1974 The purpose of this study was to ascertain the validity of agedeterminations using otoliths of jack mackerel. The study consisted of two parts: (1)otoliths were examined for seasonal changes in the hyaline and opaque zones at the edges of otoliths and (2)a dominant year class was followed through consecutive years noting marginal zone changes.
