.... Published by The Company of Biologists Ltd 2014 Egg size Maternal effects Bet-hedging Size–number trade-off A central tenet of life history theory is that mothers face a trade-off between the number and size of offspring they produce. Thus mothers must balance the benefit of making larger...

... adult body size, egg size and development time of both treatments at control as well as at elevated temperatures (test temperatures). Thus, we were able to detect genetic changes (the effects of selection temperature) and environmental effects (the effects of test temperature). We also observed the ARP...

... between thermal environments provides a direct way of assessing the adaptive significance of temperature-driven variation in egg size. Here, we examined the relationship between offspring size and performance at three temperatures for several important fitness components in the zebra fish, Danio rerio...

.... However, the extent to which variation in VTG/VLDL-R expression plays a role in determining inter-individual variation in reproductive phenotype(e.g. follicle or egg size) is not known. Here we show that the mRNA sequence of the zebra finch ( Taeniopygia guttata ) VTG/VLDL-R shows a high degree...

... volumes by 0.09±0.01 cm 3 (relative error 25.9%), and estimated clutch volumes that differed from actual volumes by 1.03±0.26 cm 3 (relative error 29.5%). We also monitored development in five lizard species and found that changes in follicle and egg size and degree of embryonic development can...
