Recruitment variability along the Antarctic Peninsula: What's the best way forward C.S. Reiss and G.M. Watters
Резюме:
This document is intended to address several issues related to the development of recruitment indices for Antarctic krill from net-tow data. We address three primary issues: 1) the view that length-frequency data collected by long-term monitoring programs that have used nets other than the RMT-8 cannot be used to parameterize Grym simulations, 2) that Read More

Recruitment variability in Antarctic krill in Subarea 48.1 expressed as ‘proportional recruitment’ D. Kinzey, J.T. Hinke, C.S. Reiss and G.M. Watters
Резюме:
Proportional recruitment is a concept that summarizes the variability of new individuals entering a population over time. Two parameters characterizing proportional recruitment, the mean and standard deviation of the interannual proportion of juveniles in the population, are important inputs to the Generalised Yield Model in R (GRYM). The GRYM is a simulation framework that defines Read More

South Shetland Island fur seals: conservation status and distribution updates D.J. Krause and G.W. Watters

As an apex krill-dependent predator, Antarctic fur seals (Arctocephalus gazella, AFS) are a key indicator species for the CCAMLR Ecosystem Monitoring Programme (CEMP). The prevailing conservation paradigm for AFS is a circumpolar, panmictic, stable population; however, a suite of recent research concludes that there are at least four strongly Read More
