Science Of Sex Video

Sex analysis is largely overlooked in marine science (Tannenbaum et al., 20=
19). A recent systematic review of ocean acidification literature, for exam=
ple, revealed that only 3.7% of recent studies tested for sex differences, =
and 85% of studies failed to consider sex at all (Ellis et al., 2017). Fail=
ing to account for such differences impacts our ability to effectively mana=
ge ecosystems and set conservation priorities.

The inclusion of sex in marine science requires challenging the widely held=
 perception that sex plays no role in determining biological responses to e=
nvironmental disturbances. We must also move beyond the assumption that sex=
 is binary, fixed, and genetically determined. Nature abounds with examples=
 of sex along a continuum, labile sex, and sex determined by an interacting=
 suite of genetic, hormonal, physiological, social and/or environmental pro=
cesses. In order to understand the importance of sex for basic biology, it =
is important to consider the mechanisms, timings, and direction of sex dete=
rmination and differentiation, as well as differences in female, male and h=
ermaphroditic responses to environmental perturbation.

Conclusions Incorporating sex analysis throughout marine and environmental =
science innovation will facilitate discovery, research efficiency, reproduc=
ibility and robustness. Recent advances in sexing technologies will enable =
wider inclusion of sex analysis throughout these disciplines and facilitate=
 better modelling of demographic change among marine organisms. This, in tu=
rn, will enhance our ability to effectively manage ecosystems and set conse=
rvation priorities.

To advance sex analysis in marine science and enhance its incorporation acr=
oss the discipline, we recommend:  1.Policy developments in funding agencie=
s and peer-reviewed journals that require sex analysis in marine science, a=
nd more broadly across the life sciences.
2.Development of novel sexing techniques for an increasingly wide array of =
non-model marine organisms, especially for species where morphological sexu=
al dimorphism is not conspicuous.
3.Development of sexing techniques to improve accessibility, reliability, c=
ost and ease. Increasing affordability of omics approaches and advancement =
of computing power will enable this endeavor.
4.Development of research that considers the role of hermaphroditism in sex=
 disaggregated reporting of results (see Analyzing Sex in Hermaphroditic Sp=
ecies). This will enable better modelling of the timing, direction and dura=
tion of sex change, as well as sex determination mechanisms. This research =
should also consider individual responses to environmental stress where cel=
ls/behaviors/physiologies of different sexes co-exist simultaneously.
5.Modelling of ecosystem functioning and responses to climate change that i=
ncorporates sex analysis, where sex disaggregated data of sufficient qualit=
y is available. Such an endeavor will improve conservation efforts and MPA =
designation/management, as well as enable better management of fisheries.=

Sex differences have been reported in various tasks ranging from cognitive1=
, to perceptual2 and motor tasks3. Thus, incorporating sex as a biological =
variable is increasingly proven relevant in behavioral and cognitive neuros=
cience4,5,6. However, the nature of these differences remains controversial=
 and their origin is largely unknown. Here we focus on visuo-oculo-manual t=
racking, a natural behavior widely used in the field of motor control7,8,9,=
10. Tracking a moving target with the hand is a neat task to investigate th=
e online control of visually guided movements because it relies heavily on =
the ability of the participant to update his/her hand motor commands on the=
 basis of ongoing visual information. Thus, studying the ability to adjust =
our movements on the fly using ongoing sensory information is critical to u=
nderstand how ones can readily achieve many of our everyday-life activities=
 such as slaloming between customers when shopping at the supermarket or pu=
rsuing an opponent during a soccer match. Last but not least, visuomotor tr=
acking is also a task tailored to investigate eye-hand coordination8,11,12,=
 another valuable skill useful in many real life situations.

In summary, the current study provides clear evidence of a difference in vi=
suomotor processing between males and females. Our results show that this m=
ale advantage does not reside in a more refined gaze strategy, or more soph=
isticated hand movements, but rather in a faster decisional process linking=
 visual information of the target with forthcoming hand actions. More gener=
ally there is a growing interest in sex differences in funding agencies, th=
e neuroscience community, as well as in medicine for drug treatment and reh=
abilitation strategies6. The current study reinforces the view that incorpo=
rating sex as a biological variable is relevant in behavioral neuroscience4=
,5.
