Are sex differences in human brain structure associated with sex differences in behaviour? [PDF]

open access: yesPsychological Science, 2021
On average, men and women differ in brain structure and behaviour, raising the possibility of a link between sex differences in brain and behaviour. But women and men are also subject to different societal and cultural norms. We navigated this challenge by investigating variability of sex-differentiated brain structure within each sex.

EVOLUTION OF SEX RATIO IN STRUCTURED DEMES [PDF]

open access: yesEvolution, 1981
In 1930 R. A. Fisher proposed an evolutionary model to explain why so many species produce roughly equal numbers of male and female offspring at birth. Very simply, since each offspring has a male and female parent (or grandparent, for haplodiploids), whichever sex is in short supply has the greater fecundity.

Optimal Sex Ratios in Structured Populations [PDF]

open access: yesJournal of Theoretical Biology, 2000
In this paper, we develop a general method to determine evolutionary equilibrium sex ratios and to check evolutionary stability, continuous stability and invadability in exact genetic models with or without dominance. This method is then applied to three kinds of models for structured populations: the first one concerns Hamilton's LMC model, except ...

Sex differences in tendon structure and function [PDF]

open access: yesJournal of Orthopaedic Research, 2017
ABSTRACTTendons play a critical role in the transmission of forces between muscles and bones, and chronic tendon injuries and diseases are among the leading causes of musculoskeletal disability. Little is known about sex‐based differences in tendon structure and function. Our objective was to evaluate the mechanical properties, biochemical composition,

Contact networks structured by sex underpin sex‐specific epidemiology of infection [PDF]

open access: yesEcology Letters, 2017
AbstractContact networks are fundamental to the transmission of infection and host sex often affects the acquisition and progression of infection. However, the epidemiological impacts of sex‐related variation in animal contact networks have rarely been investigated.

Sex versus gender associations with brain structure

open access: yesJournal of Clinical Neuroscience, 2023
In contrast to sex (a biological distinction), little is known about the associations between gender (a societal construct) and brain structure in the general population. In response to this knowledge gap, we examined the associations of sex vs. gender with FreeSurfer-generated cortical thickness and proportion-adjusted subcortical brain volume regions-

Sex difference and Allee effects shape the dynamics of sex‐structured invasions [PDF]

open access: yesJournal of Animal Ecology, 2017
Summary The rate at which a population grows and spreads can depend on individual behaviour and interactions with others. In many species with two sexes, males and females differ in key life‐history traits (e.g. growth, survival and dispersal), which can scale up to affect population rates of growth and spread.

Sex Differences in Human Brain Structure at Birth

open access: yesBiology of Sex Differences
Abstract Background Sex differences in human brain anatomy have been well-documented, though remain significantly underexplored during early development. The neonatal period is a critical stage for brain development and can provide key insights into the role that prenatal and early postnatal ...

Sacrifice, sex and structural transformation

open access: yesBijdragen tot de taal-, land- en volkenkunde / Journal of the Humanities and Social Sciences of Southeast Asia, 1988
In the same year, 1985, two scholars, working at the same university, and both specialists in Oceanic anthropology, each published a major work (with the same University Press), in which ancient Hawaii is the main focus of interest. Although the two scholars, Sahlins and Valeri, did not work together, they were close to each other in some respects.
