Distribution of Oikopleura Dioica (Tunicata, Appendicularia) associated with a coastal frontal system (39°- 41°s) of the SW Atlantic ocean in the spawning area of Engraulis Anchoita anchovy [PDF]

open access: yes, 2013
Among tunicates, the small planktonic appendicularians generally comprise a significant fraction of the mesozooplankton in frontal systems. The summer 2011 distribution (vertical and spatial) of Oikopleura dioica was studied in terms of abundance ...

Cleansing data from an electronic feeding station to improve estimation of feed efficiency

open access: yesBiosystems Engineering, 2022
Electronic feeding stations (EFS) are frequently used to automatically record feeding behaviour in pigs, but the resulting data often require cleansing. In this study, several filters were used to cleanse the data from an EFS on a commercial farm, spanning a period of 2147 days (2,709,600 records or visits, corresponding to 2748 pigs).
