“…The females exhibited species typical behavioral patterns to courting male stimuli in all three experiments with responses comparable to those reported in similar studies of female mate choice in guppies presented with live males as stimuli (Bischoff et al 1985;Reynolds and Gross 1992;Endler and Houde 1995;Houde 1997;Watt et al 2001;Karino and Matsunaga 2002). We therefore conclude that the dummy males and methodology used in this study were effective for use with female P. reticulata.…”

“…Secondly, dorsal fin and body size may influence the male's vulnerability to predators, foraging ability or otherwise affect survival and reproductive success, thereby serving as a condition-dependent indicator of male quality (Zahavi 1975;Andersson 1994). For example, larger male guppies and their offspring grow faster (Reynolds and Gross 1992), have a higher survival rate (Watt et al 2001), produce daughters with greater reproductive output (Reynolds and Gross 1992), and are better foragers on algae (Karino and Shinjo 2007) than small males. Lastly, female preference for large male fin and/or body size may be a correlated response to selection on male choice of larger, more fecund females (Halliday and Arnold 1987;Dosen and Montgomerie 2004;Herdman et al 2004).…”

Female preference for male lateral projection area in Poecilia reticulata

The lateral projection area (LPA) hypothesis was investigated by presenting female guppies, Poecilia reticulata with a series of paired males in three experiments. One trait was held constant in each experiment (dorsal fin size in expt I, body size in expt II, and total LPA in expt III) while body: dorsal fin ratio varied. Females spent more time near dummies of greater body and dorsal fin size in experiments I and II. The preference functions based on the first two sets of stimuli showed a similar pattern: the greater the LPA difference between paired dummies, the stronger the preference for the larger of the two. However, in the third experiment, neither fin size, body size, nor any particular dorsal fin+body size combination was preferred. These findings support the LPA hypothesis suggesting that increased LPA is more stimulating to sexually receptive females, and that females consequently prefer larger males. Preference for increased male dorsal fin size/LPA in both P. latipinna and P. mexicana as demonstrated in previous studies, and the more distantly related P. reticulata (shown here) is consistent with common ancestry of the sensory/ neural systems in females of all three species and perhaps the entire Poeciliid family.

“…Supporting this idea, Brooks (2000) found a negative genetic correlation between a male trait (sexual attractiveness) and survival in guppies, Poecilia reticulata . However, other studies on guppies have found that offspring of large males had higher survival rates (Watt et al. , 2001) and higher growth rates (Reynolds & Gross, 1992) than those sired by smaller males.…”

According to the ‘good genes’ hypothesis, sexual ornaments provide an indication of the ‘quality’ of the bearer. In roach, Rutilus rutilus, breeding tubercles (BTs) may signal resistance against the digenean parasite, Rhipidocotyle campanula. Life history theory predicts that there should be a trade‐off between parasite resistance and other life history traits. In roach, this could imply a trade‐off between parasite resistance in mature fish and some larval feature. We studied embryo survival and the early viability of larvae of male roach in relation to expression of BTs and parasite resistance in maternal half‐sibling families. Highly ornamented males had higher resistance against R. campanula than less ornamented males, but the BTs were not related to either embryo survival or larval viability. However, sires having higher resistance to R. campanula had lower larval viability. These results suggest that BTs of male roach do not indicate ‘quality’ in terms of early survival or viability, but rather in terms of adult parasite resistance.

Reproductive dynamics shapes genomotype composition in an allopolyploid complex

et al. 2016

Hybrid complexes are composed of organisms with multiple combinations of parental genomes (genomotypes) that interconnect through nets of crosses. Although several such complexes are well established without speciation or extinction, mechanisms shaping their dynamics remain poorly understood. In this study, we quantified the reproductive success of the allopolyploid Iberian fish Squalius alburnoides in experimental free-access and directional crosses involving the most common genomotypes. Specifically, we analysed the paternity of the offspring produced when females had free access to male genomotypes and quantified variations in egg allocation, fertilization rate, and offspring survival among crosses involving each male genomotype. The composition of the offspring produced from free-access crosses varied significantly from that expected from random mating, suggesting that offspring production and viability are not independent of parental male genomotype. Moreover, directional crosses producing the genomotype most commonly found in wild populations appeared to be the most successful, with females laying more eggs, and fertilization rate and offspring survival being the highest. These results suggest that reproductive dynamics plays a relevant role in structuring the genomotype composition of populations and opens a path to future research on the ecology and evolutionary biology of allopolyploids and their multiplicity of possible evolutionary pathways.
