Fish early life stages associated with giant kelp forests in sub-Antarctic coastal waters (Beagle Channel, Argentina)
The aim of this study was to assess seasonal and spatial variations in fish larvae abundance between areas with Macrocystis pyrifera kelp forests and areas without them off the coast of the Beagle Channel. Monthly plankton sampling at three sites was performed from June 2014 to May 2016 in two areas...

The aim of this study was to assess seasonal and spatial variations in fish larvae abundance between areas with Macrocystis pyrifera kelp forests and areas without them off the coast of the Beagle Channel. Monthly plankton sampling at three sites was performed from June 2014 to May 2016 in two areas of each site. One area was defined along the offshore margin (edge of the forests) of M. pyrifera kelp forests and the other area parallel to the forests but 200 m offshore (out of the forests). To test for spatial and temporal differences in the abundance of fish larvae, a multiple-hypothesis model approach was adopted by fitting generalized models (GLMs) with the abundance of fishes as the response variable and possible combinations of seasons, sites, areas, and water parameters as explanatory variables. Ten fish taxa in larval stage were collected of which Patagonotothen spp. larvae were the dominant group.
