Female promiscuity promotes the evolution of faster sperm in cichlid fishes
- J. Fitzpatrick, R. Montgomerie, J. K. Desjardins, K. Stiver, N. Kolm, Sigal Balshine
- Biology, Medicine

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
- K. Stiver, P. Dierkes, M. Taborsky, Sigal Balshine
- Biology
- 1 July 2004
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
- K. Stiver, P. Dierkes, M. Taborsky, H. Lisle Gibbs, Sigal Balshine

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
- K. Stiver, J. K. Desjardins, J. Fitzpatrick, B. Neff, J. Quinn, S. Balshine
- Biology, Medicine
- Molecular ecology
- 1 July 2007
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

- Biology
- Animal Behaviour
- 1 February 2008
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
- K. Stiver, J. Fitzpatrick, J. K. Desjardins, S. Balshine
- Biology
- Animal Behaviour
- 1 February 2006
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
- S. Alonzo, K. Stiver, S. Marsh-Rollo
- Biology, Medicine
- Nature communications
- 16 August 2016
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.
- N. Sopinka, J. Fitzpatrick, J. K. Desjardins, K. Stiver, S. Marsh-Rollo, S. Balshine
- Biology, Medicine
- Journal of fish biology
- 1 July 2009
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
