Predator-inspection behaviour in female three-spined sticklebacks Gasterosteus aculeatus is associated with status of gravidity.
Journal of Fish Biology, 2009Co-Authors: Joachim G. Frommen, Marion Mehlis, Theo C. M. BakkerAbstract:Differences in predator-inspection behaviour between gravid and non-gravid female as well as between male and female three-spined sticklebacks Gasterosteus aculeatus were investigated. Gravid females confronted with a live rainbow trout Oncorhynchus mykiss showed bolder inspection behaviour than non-gravid ones. The behaviour of gravid females was comparable with that of males, maybe because both face a high risk of predation. The results indicate that antipredator behaviour in female G. aculeatus is not fixed but adjusted to their reproductive state.

Cain and Abel reloaded? Kin recognition and male–male aggression in three‐spined sticklebacks Gasterosteus aculeatus L.
Journal of fish biology, 2009Co-Authors: Marion Mehlis, Theo C. M. Bakker, Kathrin Langen, Joachim G. FrommenAbstract:The influence of relatedness on male–male aggression was tested in three-spined sticklebacks Gasterosteus aculeatus. The intensity of aggression against brothers and non-kin males did not differ significantly, indicating that kin recognition plays at most a minor role in aggressive interactions between male G. aculeatus.

Inbreeding and developmental stability in three-spined sticklebacks ( Gasterosteus aculeatus L.)
Heredity, 2002Co-Authors: Dominique Mazzi, Carlo R. Largiadèr, Theo C. M. BakkerAbstract:Fluctuating asymmetry, small non-directional departures from perfect symmetry in bilateral traits, results from the inability of individuals to buffer development against genetic and environmental perturbations. Fluctuating asymmetry is a widely used measure of developmental stability, and developmental stability has been hypothesised to be inversely related to heterozygosity. We compared male three-spined sticklebacks (Gasterosteus aculeatus L.) that had been inbred for one generation to outbred control males with respect to the asymmetry of a set of bilateral morphometric traits. Inbred fish developed significantly more asymmetric pectoral fins than their outbred counterparts, whereas neither the magnitude of asymmetry for pelvic spines nor for gill covers significantly responded to the treatment. Our results conform to a pattern of heterogeneity amongst traits in their tendency to develop asymmetrically in response to stress.

Temperature and size-dependent attack rates of the three-spined stickleback (Gasterosteus aculeatus) : are sticklebacks in the Baltic Sea resource-limited?
Journal of Experimental Marine Biology and Ecology, 2014Co-Authors: Robert Lefébure, Stefan Larsson, Pär ByströmAbstract:The three-spined stickleback Gasterosteus aculeatus is a small omnivorous fish, widely distributed in the northern hemisphere. In the Baltic Sea, recently observed increases in their population den ...

Vitellogenesis in the three-spined stickleback, Gasterosteus aculeatus, over the spawning cycle and at egg overripening
2017Co-Authors: Chrysoula Roufidou, Anna Mentor, Bertil BorgAbstract:Vitellogenesis was studied in the female three-spined stickleback, Gasterosteus aculeatus, a multiple-spawning fish producing several egg batches during the breeding season, over the spawning cycle ...

Overripening of eggs and changes in reproductive hormones in the threespine stickleback, Gasterosteus aculeatus
Evolutionary Ecology Research, 2016Co-Authors: Chrysoula Roufidou, Marion Sebire, Ioanna Katsiadaki, Arshi Mustafa, Monika Schmitz, Ian Mayer, Yi Ta Shao, Bertil BorgAbstract:Background: Female threespine sticklebacks, Gasterosteus aculeatus, are batch spawners. As in most teleosts, the ovulated eggs are kept in the ovarian cavity until spawning. If spawning or spontane ...
