Sex change in scallop Patinopecten yessoensis: response to population composition? [PDF]
PeerJ, 2018 Sex structure is very labile between populations and specific for each population because it is a result of genetic, ontogenetic and biocenotic influences on the mollusks.

Protandry models and their application to salmon [PDF]
Behavioral Ecology, 2002 Mating systems characterized by restricted breeding seasons, male polygamy, and female monogamy are common among animals. In such systems (e.g., butterflies), the earlier emergence of males than females to breeding areas (protandry) is a typical phenological pattern. Protandry likely results from a timing strategy that maximizes mating opportunities by

The European Zoological Journal, 2021 Environmental factors influencing the timing of bird migration frequently affect age and sex groups differently. We applied discriminant functions to determine the sex of adult Song Thrushes ringed during spring migration in 1968–2019 at Hel on the ...

Early sex change of barramundi Lates calcarifer farmed in Singapore
Aquaculture Reports, 2021 Barramundi, Lates calcarifer, are protandrous hermaphrodites where individuals first sexually mature as male at 3−5 years of age, before reorganizing gonadal tissue to change to female several years later when they reach around 70 cm in total length (∼4 ...

The interaction between reproductive lifespan and protandry in seasonal breeders [PDF]
Journal of Evolutionary Biology, 2004 Abstract The timing and duration of reproductive activities are highly variable both at the individual and population level. Understanding how this variation evolved by natural selection is fundamental to understanding many important aspects of an organism's life history, ecology and behaviour.

IS THE FLOWER OF PULASAN (NEPHELIUM RAMBOUTAN-AKE) A PROTOGYNY OR PROTANDRY?
Floribunda, 2021 Pulasan is an androdioecious plant that has both male and hermaphrodite flowers on separate plants. The objectives of this study were to obtain data about the anatomical structure of pulasan flower and to investigate whether the pistil and the stamens of pulasan flower reach maturity at different times.

Insect Science, EarlyView.Overview of the mindset and long‐term goals with the approach suggested in this study. We provide a first proof of concept that male‐killing endosymbionts can be used to establish female biased populations with higher production efficiency than populations with a 50/50 sex ratio. This biological tool can have marked positive impact on future commercial
