Behavioural syndromes and their fitness consequences in a socially polymorphic spider, Anelosimus studiosus
TLDR
The behaviour of individuals in staged, mixed-phenotype feeding pairs indicated that social individuals may suffer fitness consequences in polymorphic populations, and results suggest linkage or pleiotropy between social behaviour and these traits. Expand
Prey Control by an Assemblage of Generalist Predators: Spiders in Garden Test Systems
TLDR
The hypothesis that generalist predators limit associated prey populations was tested using spiders, a group classically thought to be an insignificant component of the agroecosystem, and it was demonstrated that spiders were the probable cause of the effect. Expand
A test for correlations among fitness-linked behavioural traits in the spider Agelenopsis aperta (Araneae, Agelenidae)
TLDR
Spider scores in the anti-predatory fear test were an accurate predictor of the outcome of contests between individuals that were matched for weight but that had different fear scores, suggesting this entire set of traits may have the same underlying genetic basis as pleiotropic effects of the same genes. Expand
Fostering model explains variation in levels of sociality in a spider system
TLDR
An ‘assured fitness returns’ model for the evolution of sociality independent of high relatedness within colonies predicts that multiple females will cooperatively care for a brood in those environments in which a single female has a high probability of dying before her offspring are able to care for themselves.

THE HOWS AND WHYS OF SUCCESSFUL PEST SUPPRESSION BY SPIDERS: INSIGHTS FROM CASE STUDIES
TLDR
This contribution deals with how spider abundance and the mechanisms of prey control they exhibit affect their influence on prey populations in natural and agricultural systems. Expand
Sex matters: sexually dimorphic fitness consequences of a behavioural syndrome
There is growing evidence that correlated behavioural traits, or behavioural syndromes, influence behavioural evolution in some taxa. Few studies, however, investigate whether the effects of aExpand
Test for predation effects of single versus multiple species of generalist predators: spiders and their insect prey
The prediction that single spider species (as exemplary generalist predators) limit associated prey populations to the same extent that species assemblages do was tested in a well controlled andExpand
An airborne female pheromone associated with male attraction and courtship in a desert spider
TLDR
This work identified two potential sex pheromones collected from virgin, sexually mature females of the desert spider, Agelenopsis aperta, and used the synthetic compounds to test conclusions reached from previous behavioural trials indicating that chemical cues emitted by this female class attract courting males, and investigated the role of chemical communication in prescribing the complex male courtship sequence.

Frequency-Dependent Success of Cheaters During Foraging Bouts Might Limit Their Spread within Colonies of a Socially Polymorphic Spider

  • 1 November 2009
TLDR
The data indicate that asocial individuals experience negative frequency-dependent foraging success in staged foraging contests, and social individuals outperform social individuals when their representation is low, but lose this competitive advantage as their relative numbers increase. Expand
