Complex signal function: developing a framework of testable hypotheses
This work builds a framework of functional hypotheses of complex signal evolution based on content-driven (ultimate) and efficacy-driven selection pressures (sensu Guilford and Dawkins 1991), and point out key predictions for various hypotheses and discuss different approaches to uncovering complex signal function.

It is demonstrated that the mating preferences of female wolf spiders can be acquired through exposure as subadults to unrelated, sexually active adult males, and a previously uncharacterized mechanism influencing the origin of female mating preferences and ultimately the evolution of male traits is suggested.
Comparisons with published descriptions of copulatory pattern suggest that Schizocosa and Trochosa Koch 1848 may form a monophyletic clade in the "Trochosa group" of the Lycosinae and the first attempt to look at these behaviors in spiders in a phylogenetic context is presented.
Experience leads to preference: experienced females prefer brush-legged males in a population of syntopic wolf spiders
It is demonstrated that females from this population of wolf spiders will differentially choose between males of 2 distinct forms based on prior experience, and it is shown that brush-legged males are more sexually aggressive than non-ornamented males.
Attention-altering signal interactions in the multimodal courtship display of the wolf spider Schizocosa uetzi
Females were more likely to get caught, and thus less likely to notice a predatory visual stimulus when exposed to a courtship vibration, supporting the hypothesis that the vibratory signal alters a female’s visual attention.
Geographical variation in male courtship behaviour and sexual isolation in wolf spiders of the genusSchizocosa
Although there was no clinal pattern in the frequency of courtship behaviour, it is suggested that sexual isolation occurs among populations in different physiographical regions but not between populations within regions of the state.
Relating the unique sensory system of amblypygids to the ecology and behavior of Phrynus parvulus from Costa Rica (Arachnida, Amblypygi)
While the unique sensory system and neuroanatomy of amblypygids suggest that olfaction is important in their lives, to date no behavioral data exist to support this suggestion. To gain insight into...
An introduction to multimodal communication
The history of the study of complexity in animal communication, issues relating to defining and classifying multi-modal signals, and particular issues to consider with multimodal (as opposed to multicomponent unimodal) communication are discussed.
