 A recent study by Johnson et al. (2017) found another factor capable of influencing sex determination in lampreys: the availability of resources. The authors experimentally manipulated environmental productivity (a proxy for the amount of resources available) in which larvae grew and found that it influenced adults’ sex ratio. Populations of individuals that grew in sites with lower productivity resulted in biased sex-ratio towards males.
-There is wide evidence showing how the amount of resources influences life history traits. Individuals that grow with abundant resources can allocate them on both tissue growth and reproduction. However, when faced with restriction of resources, individuals tend to invest in somatic growth rather than reproduction. A similar trade-off exists in sex allocation, since female eggs cost than male sperm to produce. The question then is how this trade-off determines sex bias.
