DOI: 10.1002/ece3.5566
Abstract: Abstract Sex allocation (SA) theory for simultaneous hermaphrodites predicts an influence of group size on SA. Since group size can vary within an individual's lifetime, this can favor the evolution of phenotypically plastic SA. In… read more here.

DOI: 10.1007/s00497-017-0303-4
Abstract: Key messageSex allocation in Cyananthus delavayi.AbstractGynodioecy, where females and hermaphrodites coexist in the same natural population, is particularly suitable for predicting the ecological pressures that drive the stability of gender polymorphism. Since females have a… read more here.

Density-dependent dispersal promotes female-biased sex allocation in viscous populations

DOI: 10.1098/rsbl.2022.0205
Abstract: A surprising result emerging from the theory of sex allocation is that the optimal sex ratio is predicted to be completely independent of the rate of dispersal. This striking invariance result has stimulated a huge… read more here.

DOI: 10.1098/rstb.2021.0500
Abstract: The study of sex allocation—that is, the investment of resources into male versus female reproductive effort—yields among the best quantitative evidence for Darwinian adaptation, and has long enjoyed a tight and productive interplay of theoretical… read more here.

DOI: 10.1111/ele.12929
Abstract: Cyclical parthenogenesis presents an interesting challenge for the study of sex allocation, as individuals' allocation decisions involve both the choice between sexual and asexual reproduction, and the choice between sons and daughters. Male production is… read more here.

Sex allocation and sex‐specific parental investment in an endangered seabird
Sign Up to like & getrecommendations! Published in 2017 at "Ibis"
DOI: 10.1111/ibi.12457
Abstract: Biased offspring sex ratio is relatively rare in birds and sex allocation can vary with environmental conditions, with the larger and more costly sex, which can be either the male or female depending on species,… read more here.

Consequences of population structure for sex allocation and sexual conflict
Sign Up to like & getrecommendations! Published in 2020 at "Journal of Evolutionary Biology"
DOI: 10.1111/jeb.13755
Abstract: Both sex allocation and sexual conflict can be modulated by spatial structure. However, how the interplay between the type of dispersal and the scale of competition simultaneously affects these traits in sub‐divided populations is rarely… read more here.

DOI: 10.1186/s12864-020-06904-4
Abstract: Whilst adaptive facultative sex allocation has been widely studied at the phenotypic level across a broad range of organisms, we still know remarkably little about its genetic architecture. Here, we explore the genome-wide basis of… read more here.

Mating behavior and reproductive morphology predict macroevolution of sex allocation in hermaphroditic flatworms
Sign Up to like & getrecommendations! Published in 2022 at "BMC Biology"
DOI: 10.1186/s12915-022-01234-1
Abstract: Background Sex allocation is the distribution of resources to male or female reproduction. In hermaphrodites, this concerns an individual’s resource allocation to, for example, the production of male or female gametes. Macroevolutionary studies across hermaphroditic… read more here.

DOI: 10.3389/fmars.2018.00260
Abstract: Background: In protandric-simultaneous (PS) hermaphrodites, individuals invariably reproduce as males first and later in life as simultaneous hermaphrodites. Here, the shrimp Lysmata wurdemanni was used as a model to (i) test for the role of… read more here.
