Sexual Selection and Mixed Sex Expression: Adolescent Protandry, Phenotypic Tradeoffs and ‘Unconventional' Sex Allocation Estimates in a Protandric-Simultaneous Hermaphrodite

open access: yesFrontiers in Marine Science, 2018
In protandric-simultaneous (PS) hermaphrodites, individuals invariably reproduce as males first and later in life as simultaneous hermaphrodites. In this study, the shrimp Lysmata wurdemanni (Gibbes, 1850) was used as a model to (i) test for the role of ...
