SELFING AND OUTCROSSING. "Classical theory on mating system evolution suggests that simultaneous hermaphrodites should either outcross if they have high inbreeding depression (ID) or self-fertilize if they have low ID. However, a mixture of selfing and outcrossing persists in many species." https://lnkd.in/ehVZ44Z View in LinkedIn

DARWINIAN ADAPTATION. "Sex allocation theory is considered as a touchstone of evolutionary biology, providing some of the best supported examples for Darwinian adaptation." https://lnkd.in/eP698dz View in LinkedIn

FINDING. "The functional significance of floral display is not the total number of flowers produced by an inflorescence or ramet but rather the number of flowers in anthesis each day." https://lnkd.in/encXPYB View in LinkedIn

FLOWER DURATION. "Studies investigating flower dimorphism and floral display with unisexual flowers (monoecy or dioecy) often report male function extends the duration of their floral displays through producing or opening only a fraction of their flowers each day compared to female function." https://lnkd.in/encXPYB View in LinkedIn

IMPACT OF SEX RATIO. "In monoecious populations, the floral sex ratio also has the potential to affect mating opportunities. Pollinator-meditated selection should result in larger male floral displays and hence higher ratio of male to female flowers, because the number of male flowers influences pollen production and attraction to pollinators. On the other hand, sexual selection should favor extended duration of male function, thus increasing the number and variety of mating partners." https://lnkd.in/encXPYB View in LinkedIn

PREVAILING PREMISE. "Theoretical studies have predicted that reproductive asynchrony, which occurs when males and females are reproductively active at different times, could increase reproductive failure as the probability of temporal overlap of potential mates, especially in small populations, is reduced." https://lnkd.in/encXPYB View in LinkedIn

MANGROVE FISH SELFING CONSEQUENCES. "Because sex change is environmentally driven and because rivulus produces isogenic lineages via selfing, hermaphrodites and secondary males with identical genotypes can be produced." https://lnkd.in/dfG4sX2 View in LinkedIn

MANGROVE FISH SELFING PREFERRED. "Outcrossing can be quite prevalent and can drive substantial levels of heterozygosity in some populations, but the most common mode of reproduction for mangrove rivulus is self-fertilization or ‘selfing’. Repeated bouts of selfing can result in completely homozygous individuals capable of producing offspring that are genetically identical to the parent and all siblings." https://lnkd.in/dfG4sX2 View in LinkedIn

CLASSIFICATION. "Males are categorized either as primary, where embryos develop as males, or secondary, where an adult hermaphrodite transitions to male. Outcrossing can occur between males and hermaphrodites, but never between hermaphrodites." https://lnkd.in/dfG4sX2 View in LinkedIn

FREQUENCY. "In most cases of sex change, individuals transition once in their lifetime either from male to female (e.g. protandry) or from female to male (e.g. protogyny), but there are exceptions (e.g. ‘repetitive sex change’)." https://lnkd.in/dfG4sX2 View in LinkedIn
