Female promiscuity promotes the evolution of faster sperm in cichlid fishes
Sperm competition, the contest among ejaculates from rival males to fertilize ova of a female, is a common and powerful evolutionary force influencing ejaculate traits. During competitive… Expand

Dispersal patterns and status change in a co‐operatively breeding cichlid Neolamprologus pulcher: evidence from microsatellite analyses and behavioural observations
Genetic techniques and long-term behavioural observations were combined to investigate dispersal patterns and changes in social position in Neolamprologus pulcher, a co-operatively breeding cichlid… Expand

Female-mediated causes and consequences of status change in a social fish
In highly social species, dominant individuals often monopolize reproduction, resulting in reproductive investment that is status dependent. Yet, for subordinates, who typically invest less in… Expand

Relatedness and helping in fish: examining the theoretical predictions
Many studies have attempted to explain the evolution of cooperation, yet little attention has been paid to what factors control the amount or kind of cooperation performed. Kin selection theory… Expand

Evidence for size and sex‐specific dispersal in a cooperatively breeding cichlid fish
African Great Lake cichlid populations are divided into thousands of genetic subpopulations. The low gene flow between these subpopulations is thought to result from high degrees of natal philopatry,… Expand

Differential responses to territory intrusions in cooperatively breeding fish
In cooperatively breeding species, members of social groups will risk serious injury or even their lives by actively codefending the communal territory and young in the territory. However,… Expand

Sex differences in rates of territory joining and inheritance in a cooperatively breeding cichlid fish
In social groups, subordinates may gain dominant breeding status either by inheriting the top position in their current group or by dispersing to join a new group. The pathway to breeder status is… Expand

Ovarian fluid allows directional cryptic female choice despite external fertilization
In species with internal fertilization, females can favour certain males over others, not only before mating but also within the female's reproductive tract after mating. Here, we ask whether such… Expand

Parental and Mating Effort: Is There Necessarily a Trade‐Off?
One of the common assumptions in the study of the evolution of parental care is that trade-offs exist between parental investment and other fitness-related traits. In general, this body of work… Expand

Liver size reveals social status in the African cichlid Neolamprologus pulcher.
Wild groups (n = 167) of the cooperatively breeding Lake Tanganyika cichlid, Neolamprologus pulcher, were used to investigate how social status and sex influence liver investment. In contrast to… Expand
