Broodcare helpers in the cichlid fish Lamprologus brichardi: Their costs and benefits
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.
Paying to stay or paying to breed? Field evidence for direct benefits of helping behavior in a cooperatively breeding fish
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.
Animal personality due to social niche specialisation.
Alternative reproductive tactics : an integrative approach
The evolution of alternative mating tactics: concepts and questions Michael Taborsky, Rui F. Oliveira and H. Jane Brockmann examine the role of genes and the environment in the expression and evolution ofAlternative reproductive tactics.
What sets the odds of winning and losing?
It is proposed here that two hypotheses are particularly important among the potential adaptive explanations: the 'social-cue hypothesis', which assumes that victory and defeat leave traces that affect the decisions of subsequent opponents; and the 'self-assessment hypothesis',Which assumes that winners and losers gain information about their own relative fighting ability in the population.
The evolution of alternative reproductive tactics: concepts and questions
The meaning of the term alternative reproductive tactics, or ARTs, is outlined, and why the existence of ARTs is so widespread in animals is discussed, and the importance of general principles such as frequency dependence, density dependence, and condition dependence is asked.
Helpers in fish
Field data show that in the cichlid fish Lamprologus brichardi conspecifics other than the reproducing pair help in brood care and territory maintenance, with the expected degree of relatedness decreasing with the helper's age.
Inclusive fitness theory and eusociality
It is argued that inclusive fitness theory has been of little value in explained the natural world, and that it has led to negligible progress in explaining the evolution of eusociality, but these arguments are based upon a misunderstanding of evolutionary theory and a misrepresentation of the empirical literature.
