Morph-specific fecundity and egg size in the female-dimorphic damselfly Ischnura senegalensis.
Females of coenagrionid damselflies exhibit color dimorphism, consisting of an andromorph and a gynomorph. This study compared reproductive traits between the female morphs in both field-captured and laboratory-reared females of the female-dimorphic damselfly Ischnura senegalensis. No difference was found in the onset of egg development between the morphs. The andromorphs developed significantl...

متن کاملSperm quality, egg size, fecundity and their relationships with fertilization rate of grass carp (Ctenopharyngodon idella)
Gametes were collected by abdominal massage from 15 anesthesized male and female grass carp. In collected sperm samples the following mean spermatological properties were determined: sperm volume 15.64 ± 5.39 mL, sperm motility 81.20 ± 7.61%, motility duration 62.06 ± 19.40s, density 17.88±5.48 x109 mL-1, total density 428.90±302.05 x109, and pH 7.25±0.81. Also egg size (mm) and fecundity (egg...
متن کاملRevisiting the positive correlation between female size and egg size
Positive correlations between maternal size and propagule (egg, seed, embryo) size could arise for several reasons. One of these is that larger mothers may improve the survival of their offspring during a stage when large propagules typically have lower survival than small propagules. We previously developed an optimality model that incorporated this effect and used it to explain the positive c...
