Fish populations are often treated as homogeneous units in typical fishery management, thereby tacitly ignoring potential intraspecific variation which can lead to imprecise management rules. However, intraspecific variation in life-history traits is widespread and related to a variety of factors. We investigated the comparative age-based demography of the(More)
Sex ratio is a fundamental demographic parameter with major implications for the dynamics, management, and conservation of animal populations. The objective was to study the main factors affecting the post-settlement population sex ratio (SR) of Octopus vulgaris off the NE Atlantic. We investigated the spatio-temporal dynamics in SR using more than 115,000(More)
