Abstract Abstract. Observations on the reproductive behaviour and polygynous mating system of an endemic shell-brooding cichlid fish, Lamprologus callipterus , revealed that territorial males actively transported and accumulated spawning substrate (empty gastropod shells) to make nests. In contrast to conventional resource defence polygyny, males of this species can therefore create a defensible resource distribution. Females successively visited the nests, chose one shell, spawned the whole… Expand
Unusual allometry for sexual size dimorphism in a cichlid where males are extremely larger than females
TLDR
It is reported that the allometric relationship was negative across populations of a shell-brooding cichlid fish Lamprologus callipterus, although males are extremely larger than females, suggesting that females are more strongly subject to size selection associated with shell size availability than males. Expand
Sexual selection promotes colonial breeding in shell-brooding cichlid fish
TLDR
Female preference suggests that sexual selection affects colonial breeding in L. callipterus, which implies an influence of sexual selection on the evolution of colonial breeding at large. Expand
Reproductive investment of giants and dwarfs: specialized tactics in a cichlid fish with alternative male morphs
TLDR
It is argued that capital and income breeding are useful concepts to understand divergent life history decisions associated with alternative reproductive tactics, i.e. behavioural polymorphisms within a species and within one sex. Expand
Sexual conflict over breeding substrate causes female expulsion and offspring loss in a cichlid fish
TLDR
It is concluded that the limited availability of breeding substrate is a key determinant of both intrasexual competition and intersexual conflict in this species. Expand
An optimality approach to male and female body sizes in an extremely size-dimorphic cichlid fish
TLDR
Intersexual selection can explain male body size, but fecundity selection alone cannot explain female size, and the breeding substrate strongly constrains female size. Expand
Nest use by territorial males in a shell-brooding cichlid: the effect of reproductive parasitism
TLDR
The results suggest that larger territorial males selected nests that have a lower risk of usurpation of spawning and the risk of intrusion by pirate males affects the selection of nests by territorial males in this species. Expand
The influence of sexual selection and ecological constraints on an extreme sexual size dimorphism in a cichlid
TLDR
It is concluded that the divergent influence of an ecological constraint on male and female body sizes is primarily responsible for this extreme SSD in Lamprologus callipterus, in combination with size-dependent mechanisms of intrasexual selection. Expand
Size-Dependent Male Alternative Reproductive Tactics in the Shell-Brooding Cichlid Fish Lamprologus callipterus in Lake Tanganyika
TLDR
The analyses of body condition among ripe and unripe males across a wide range of body sizes suggested that onset of sexual activities at very small body sizes in dwarf males may be associated with higher condition factors that is a pre-requisite for maintaining investment in testes and intense reproductive activities.

Giant males or dwarf females : what determines the extreme sexual size dimorphism in Lamprologus callipterus?
TLDR
It seems unlikely that L. callipterus descended from small shell-brooding cichlids which used shells for shelter, but more likely that the ancestors were of large or intermediate size, and that female size is constrained by the sizes of snail shells, which appear to be optimal breeding substrata.

Conservation implications of the provenance of modern sediment on a shell-rich platform of Lake Tanganyika (Kigoma, TZ)
Abstract Shell-rich substrate (shell beds) in the littoral reaches of Lake Tanganyika, Africa, form a unique substrate that host a number of endemic organisms, including sponges and shell-dwellingExpand
