When being alive implies being safe: Variation in mortality can cause oviposition selectivity to increase with age
Article Abstract:
The spatial variation in mortality rates creates an additional mechanism able to select for an increase in selectivity with age. Females are selected to the fact of having reached and advanced age as a cue of low mortality rates, where older females may be less time-limited and can afford for more careful host selection, hence the variation in mortality rates can cause a positive correlation between individual age and expected residual life span.

Sexual size dimorphism within species increases with body size in insects
Article Abstract:
An analysis was conducted to examine dependence of sexual size dimorphism (SSD) on body size, the latter variable being used as a proxy of environmental quality. The results suggest that environmental conditions may strongly affect the degree, though not the direction of SSD within species.
