Being a protandrous
species, it was possible to determine the length of the parasites which pass from male to female and changed its behaviour from a free life to a life exclusively parasitic.
Although the majority of threadfin species are apparently protandrous
hermaphrodites, a few are gonochoristic (Dentzau and Chittenden Jr, 1990).
Sex differential nectar secretion in protandrous
Alstroemeria aurea (Alstroemeriaceae): is production altered by pollen removal and receipt?
arrival timing to breeding areas: a review.
Relative fitness of selfed and outcrossed progeny in a self-compatible, protandrous
species, Sabatia angularis L.
alba is predominantly allogamous and protandrous
(Arroyo, 1975; McNeill, 1983), several geographically isolated populations seem to have allelic diversity for self-pollination (Tables 2 and 3).
Chasmogamous flowers in this genus are strongly protandrous
, making these plants amenable to controlled pollinations and quantitative genetic mating designs (e.
Once a critical temperature threshold has been attained, these viviparous, protandrous
, serial bidirectional hermaphrodites spawn and begin brooding their larvae for 10-12 days before releasing D-stage veligers into the water column (Coe 1931, Hopkins 1937).
Photoperiod and temperature effects on the spawning time, fecundity and hatching success of a protandrous

A novel protandrous
sexual system was described in the hippolytid carideans Lysmata wurdemanni (Gibbs, 1850) (Bauer and Holt, 1998) and Lysmata amboinensis (de Man, 1888) (Fiedler, 1998), in which individuals first develop as males, then later change to simultaneous hermaphrodites with a primarily female phenotype.
Gonad development, growth survival and quality traits in triploids of the protandrous

This monoecious species has protandrous
inflorescences, is pollinated by beetles and bees (Kuchmeister et al.
