Broodcare helpers in the cichlid fish Lamprologus brichardi: Their costs and benefits
TLDR
Three factors proved to be of major impor- tance in the cost-benefit analysis of helping as opposed to leaving for family-independent non- reproductive aggregations: investment, mortality risk and protection.About:

Sneakers, Satellites, and Helpers: Parasitic and Cooperative Behavior in Fish Reproduction
TL;DR: This chapter reviews the current knowledge of the ways in which fish compete at different levels of sexual reproduction and describes how competition for resources may lead to cooperative behavior, even between the competitors themselves.
BookDOI
Ecology and evolution of cooperative breeding in birds
TL;DR: This book presents a meta-anatomy of sexual selection in birds and mammals, focusing on the role of courtship and courtship strategies in the courtship of birds and mammal species.
Journal ArticleDOI
Investment and relatedness: A cost/benefit analysis of breeding and helping in the pied kingfisher (Ceryle rudis)
TL;DR: It is concluded that (a) breeding is superior to helping and helping superior to doing nothing and (b) that kin-selection must be invoked to explain why surplus males choose the more costly primary helper strategy instead of the cheaper secondary helper strategy.
Journal ArticleDOI
Paying to stay or paying to breed? Field evidence for direct benefits of helping behavior in a cooperatively breeding fish
TL;DR: Two field experiments conducted to test the "territory inheritance" and "pay-to-stay" hypotheses in the cooperatively breeding cichlid fish Neolamprologus pulcher support both hypotheses, and helpers gain direct benefits from helping behavior.
Journal ArticleDOI
Fish Intelligence, Sentience and Ethics
TL;DR: The current state of knowledge of fish cognition is reviewed starting with their sensory perception and moving on to cognition, revealing that fish perception and cognitive abilities often match or exceed other vertebrates.

The Genetical Evolution of Social Behaviour. I
TL;DR: A genetical mathematical model is described which allows for interactions between relatives on one another's fitness and a quantity is found which incorporates the maximizing property of Darwinian fitness, named “inclusive fitness”.

The Evolution of Helping. I. An Ecological Constraints Model
TL;DR: It is argued that a necessary first step for the evolution of cooperative breeding is a substructuring of the population into small, stable, social units; in most known cases these are extended-family units.
