Sexual selection, parasites and bower height skew in a bower-building cichlid fish
Article Abstract:
The relationship between spawning success and courtship was examined in bower-building cichlid fish from Lake Malawi, Africa. The results showed that the structure of a phenotypic character was inversely proportional to the male parasitic load, with spawning males having substantially fewer dilepipid cestodes in their livers compared to non-spawning males. Moreover, spawning males have substantially heavier gonads compared to unsuccessful males. Results also revealed a correlation between reproductive success and relative liver weight.

Are bowerbird displays cheap?
Article Abstract:
The results of Borgia's study on the alleged low-cost epigamic traits of the satin bowerbirds support the hypothesis that displays are costly to the bearers. Mortality rate during the mating season is irrelevant on the issue of display costs because other activities by male bowerbirds may produce mortality. Finally, display components are cheap otherwise males would only provide additional decorations to their bowers

Local traditions of bower decoration by spotted bowerbirds in a single population
Article Abstract:
A study is conducted to show that elaborate secondary sexual traits and the corresponding preferences for the study may be transmitted culturally rather than by genetic inheritance. The study concludes that bowers built by male spotted bowerbirds, Chlamydera maculata, within a single population indicate fine scale similarities between neighbours in the decorations displayed on them.
