“…On the other hand, in many species sequential choice tests clearly elicit a response when mate choice is considered (e.g., Bakker and Milinski 1991;Bateman et al 2001;Pitcher et al 2003;Wong et al 2004). Still, female sailfin mollies (Poecilia latipinna) show weaker expression of mating preferences in sequential tests compared with simultaneous designs (MacLaren and Rowland 2006). Like in the present study, social attraction may override an existing preference in the sequential choice situation.…”

A test for conspecific cueing in two sympatric species of pupfish (Cyprinodon beltrani, C. simus)

In many fishes, individuals prefer to associate with phenotypically similar or conspecific individuals (conspecific cueing). Such phenotypic segregation can be an important evolutionary driver, for example, in intralacustric sympatric speciation processes. I examined conspecific cueing in two species of sympatric pupfish from Laguna Chichancanab in southern Mexico: the little shoaling and highly territorial Cyprinodon beltrani and the highly shoaling but non-territorial C. simus. Females were tested for shoal species preferences in two testing scenarios:(1) a sequential choice test where shoals of four conspecific or four heterospecific (Cyprinodon sp. or Poecilia reticulata) females were presented in succession, and (2) a simultaneous choice test where female shoals of both Cyprindon species were presented concurrently. Overall, higher shoaling in C. simus was corroborated in this study. In the sequential test, no effect of the type of stimulus shoal (con-or heterospecific) on shoaling behavior was detected. In the simultaneous tests, C. beltrani, but not C. simus females showed a preference for the conspecific shoal. It seems possible that C. simus females did not evolve species recognition mechanisms because no other Cyprinodon species in the Laguna Chichancanab shows equally high shoaling, which automatically leads to the formation of singlespecies (i.e., C. simus-) shoals. C. simus males do not establish long-term territories, but rather spawn within shoals, whereas C. beltrani females approach males in their breeding territories to spawn. I discuss that this behavioral difference still provides a powerful reproductive isolation mechanism even in the absence of conspecific cueing in C. simus.

“…We cannot entirely exclude that the difference in outcome is due to the fact that we presented the intruder mounts simultaneously in the resident males' territories, whereas Alonso-Alvarez et al (2004) presented the models sequentially. However, this methodological difference seems an unlikely explanation for the lack of effect in our study, because choice tests with simultaneous presentation of test stimuli are believed to generally give higher resolution in discrimination by the focal animal (MacLaren & Rowland, 2006). Also, the encounter of more than one opponent at the same time is not an unusual situation for wild blue tits, because agonistic interactions regularly involve more than two individuals, especially within winter foraging flocks (Korsten, P., personal observation).…”

“…We presented the two male mounts with the different UV treatments simultaneously. This new experimental set-up has the advantage of a direct comparison of resident males' reactions to the different intruder types, while controlling for irrelevant variation in male reactions due to for example differences in the timing of the mount presentation, the motivation of the males, or the presence or absence of the female mate during the simulated intrusion (for further discussion of sequential versus simultaneous stimulus presentations in choice tests, see also MacLaren & Rowland, 2006). To control for possible mount effects we switched the UV-reduced and control treatment regularly between both mounts.…”

SummaryStructurally-based ultraviolet (UV) coloration of plumage can signal male quality and plays a role in female mate choice in many bird species. UV-reflecting badges could also be important signals in male-male competition. We tested if territorial blue tit (Cyanistes caeruleus) males discriminate between conspecific male intruders which differ in the UV reflectance of their crown feathers. To this aim, we used a new experimental approach in which we simultaneously (instead of sequentially) introduced two male blue tit taxidermic mounts in the territories of resident males during the female fertile period; one mount with natural crown UV reflectance and one mount with reduced crown UV. The two mounts provoked strong aggressive reactions from resident males. Males specifically directed their aggression to conspecific intruders, as a male blue tit mount received substantially more aggression than a mount of a European robin (Erithacus rubecula). However, aggression of resident males did not vary between the UV-reduced and the control mount. Furthermore, the variation in natural crown UV reflectance of the resident males did not predict the intensity of their aggressive response. Contrary to previous findings our results suggest that UV signals play only a limited role in male-male interactions during territorial intrusions in the female fertile period.

“…First, shoaling may increase levels of female–female competition (Forsgren et al , 2004). Second, ready‐to‐spawn males will typically encounter many females simultaneously, making direct comparisons easier (MacLaren & Rowland, 2006) and reducing costs of male choice (Wagner, 1998; Wong & Svensson, 2009). Indeed, G. flavescens males strongly prefer the most ornamented of simultaneously presented females (Amundsen & Forsgren, 2001).…”

Female ornamentation and egg carotenoids of six sympatric gobies

Belly colouration, gonad carotenoid concentration and skin transparency were quantified in gravid Gobiusculus flavescens, as well as in females of five sympatric gobies where belly ornamentation has not been described. Although G. flavescens females did, indeed, have far more colourful bellies than the other species, this could only in part be explained by a high concentration of total gonad carotenoids. Comparable, or occasionally higher, carotenoid levels were found in the gonads of other species. Instead, the unusual ornamentation of G. flavescens arises from a unique combination of carotenoid-rich gonads and a highly transparent abdominal skin.
