Most of the studies fail to adequately demonstrate an unambiguous relationship between vigilance behaviour and group size, but many studies reveal interesting features of the relationship between Vigilance and Group size that should provide fruitful avenues for future research.
The functional significance of silk decorations of orb‐web spiders: a critical review of the empirical evidence

A phylogenetic analysis of the different decoration patterns suggests that the different types of decorations are as evolutionary labile as the decorations themselves: the analysis shows little homology and numerous convergences and independent gains.

It is shown that a recently proposed index designed to rank scientists fairly is in fact strongly biased against female researchers, and advocate a modified index to assess men and women on a more equitable basis.
Sexual Cannibalism in Orb-Weaving Spiders: An Economic Model
The model demonstrates that cannibalism of courting males by virgin females can arise purely through foraging considerations and that the most important factors for the evolution of this behavior are the expected number of males encountered during the season and the distribution of mass gained from other prey items.
FAITHFUL WITHOUT CARE: THE EVOLUTION OF MONOGYNY

Using a mathematical model, it is shown that monogyny as a means of increasing paternity is favored when the sex ratio is male biased, but not necessarily by high search costs.

Spiders experiencing low prey encounter rates constructed larger webs and incorporated more silk but fewer web decorations than spiders experiencing high prey encounter Rates, which indicates foraging success by attracting prey to the web.
SEXUAL CANNIBALISM, SIZE DIMORPHISM, AND COURTSHIP BEHAVIOR IN ORB‐WEAVING SPIDERS (ARANEIDAE)

The relationship between sexual cannibalism and sexual size dimorphism may be rather more complex and the location of mating and courtship may be one factor that provides further explanation of the variation in sexual sizeDimorphism in orb-weaving spiders.
