Acoustic target strength (TS) of argentine anchovy (Engraulis anchoita): the nighttime scattering layer [PDF]
ICES Journal of Marine Science, 2016 Engraulis anchoita is a physostomous fish with a dual chambered swimbladder (sb). In situ target strength (TS) measurements on this species are only possible at night, when anchovies disperse forming a scattering layer near the sea surface. A survey data series comprising more than 50000 single target detections, recorded from 1995 to 2008, was ...

Partial migration in Magellanic penguins
Journal of Avian Biology, Volume 2024, Issue 3-4, March/April 2024.We studied the migration of Magellanic penguins near the southern tip of the breeding distribution, and for the first time found evidence of partial migration for this species within the same colony. Forty‐three percent of the penguins studied stayed within ~ 290 km of the colony (residents), while others went northwards as far as 2000 km. All penguins
