Exploring Animal Social Networks
This paper presents a meta-modelling framework for estimating the values of node-based measures and describes its use in a number of real-world situations.
Social network theory in the behavioural sciences: potential applications
This review identifies several broad research areas where the networks approach could greatly enhance the understanding of social patterns and processes in animals.

It is asserted that social fine structure in Trinidadian guppies is strongly influenced by behavioural trait and will have implications for the outcome of selection on behavioural traits and speculated that the observed positive assortment may act as an amplifier of selection contributing to the maintenance of co-operation during predator inspection.
Ecological Knowledge, Leadership, and the Evolution of Menopause in Killer Whales
Shoal composition determines foraging success in the guppy
This study highlights a possible mechanism by which interindividual variation in behavioral types is maintained in a population of guppies using an overhead fright stimulus and suggests potential foraging benefits to bold individuals through associating with shy individuals.
Social networks in the guppy (Poecilia reticulata)
Stable partner associations between individuals were observed, a finding that fulfils the basic prerequisite for the evolution of reciprocal altruism.
Assortative interactions and social networks in fish
The mechanisms underpinning the structure of social networks in multiple fish populations were investigated and the occurrence of repeated interactions between pairs of individuals fulfils an important pre-requisite for the evolution of reciprocal altruism.
Potential banana skins in animal social network analysis
This work suggests that more attention should be given to whether relational data are representative, the potential effect of observational errors and the choice and use of statistical tests in the study of animal social networks.
Adaptive Prolonged Postreproductive Life Span in Killer Whales
Using multigenerational records for two killer whale populations in which females can live for decades after their final parturition, it is shown that postreproductive mothers increase the survival of offspring, particularly their older male offspring.
