Sexual dimorphism and female advantage hypothesis in Dianthus plumarius (Caryophyllaceae)
<p>I tested the sexual dimorphism trade-off hypothesis with the gynomonoecious-gynodioecious <i>Dianthus plumarius </i>(Caryophyllaceae). I measured in female and hermaphrodite plants: flower size, nectar volume and concentration, flower lifespan, ovule production, seed number, seed set, and seed weight. Additionally, bagging and pollen supplementation experiments were carried out to evaluate pollen limitation, probability of apomixis, if spontaneous autogamy is possible, and to examine the importance of pollen origin. </p>
Fig. 3 in Sexual Dimorphism in North American Coccinellids: Sexing Methods for Species of Coccinella L. (Coleoptera: Coccinellidae) and Implications for Conservation Research
Fig. 3. Male Coccinella novemnotata showing the white spot on the anterior face of the anterior coxa (left arrow) and white stripe on the ventral face of the anterior femur. Females always lack and males of this species always have these characters, which are visible with the unaided eye. See Table 3 for occurrence of this character in other North American Coccinella species. Photograph by Todd A. Ugine.

Fig. 1. Ventral view of a female (top) and male (bottom) Coccinella novemnotata showing the dimorphic seventh abdominal sternite (S7, outlined) and the location of the five measurements taken from all specimens. Note the emargination at the midline in the male. This constriction was estimated using hm-prop (hm divided by the average of hl and hr). Photogtaphs by L. Stellwag.
Fig. 2 in Sexual Dimorphism in North American Coccinellids: Sexing Methods for Species of Coccinella L. (Coleoptera: Coccinellidae) and Implications for Conservation Research
Fig. 2. Pronotal pigment pattern on a female (top) and male (bottom) of Coccinella novemnotata. Two measurements were taken: the width at the widest anterior points (p-width) and the depth from the pigment edge at the midline to a line drawn to connect the two endpoints from the width measurement (p-depth). To control for size differences between males and females, p-depth was divided by p-width and this proportion was used for analysis (p-prop). Photographs by L. Stellwag.
