Why do males and females of some species look so different?
12-04-2006 · EurekAlert!Why and how do males and females of the same species often look so different? Armin Mocsek (Indiana University) has shown that in a certain group of insects, sex-differences in appearance are not the product of growing structures in a sex-specific manner, as previously assumed, but rather are generated by the sex-specific loss, or removal, of structures initially grown alike by both males and females.

- How are phenotypic differences between sexes related to phenotypic variation within sexes?
01-10-2007 · EurekAlert!
It has long been recognized that sexually dimorphic traits -- traits that are systematically different between members of different sex in the same species, such as peacocks' tail feathers -- tend to vary a great deal among individual males, and that much of this within-sex variation depends on individual condition. Indeed, theory predicts that sexual dimorphism will evolve based on condition dependence so that, among traits, a more pronounced difference between male and female should be associated with a stronger response to variation in condition.

- Cardio exercise benefits in male vs. female hearts
08-08-2007 · EurekAlert!
A new study examining chronic exercise in male and female mice finds that moderate long-term exercise provokes a sex-dependent cardiac adaptation that is different for females versus males. The findings may eventually help improve treatment strategies for women and men with heart disease.

- For Pacific white shrimp, gender matters when competing for food
12-12-2006 · EurekAlert!
A new study in Journal of the World Aquaculture Society suggests that, while larger shrimp consistently win over smaller shrimp of the same gender when competing for food, male shrimp will almost always beat female shrimp -- even though adult males of the species are typically much smaller than the adult females of the same age.

- Opposites do not attract
11-13-2006 · EurekAlert!
A study conducted at the University of California, Irvine, found that a female budgerigar prefers to mate with a male that sounds like her. Biologists Marin Moravec, Professor Nancy Burley and Professor Georg Striedter conducted the study, which was published in Ethology in early November. The study also found that males that paired with more similar-sounding females gave more help to the females when they were nesting.

- The love song of male túngara frogs
02-08-2007 · EurekAlert!
Male túngara frogs produce two types of calls to attract females: simple and complex. Female túngara frogs, as well as unintended receivers such as frog-eating bats and blood-sucking flies, prefer complex to simple mating calls. Bernal et al. tested whether bats and flies prefer complex calls because they indicate higher quality males and/or higher male density. The authors found that call complexity indicate higher abundance of prey/host.

- Sex is thirst-quenching for female beetles
08-28-2007 · EurekAlert!
Female beetles mate to quench their thirst according to new research by a University of Exeter biologist. The males of some insect species, including certain types of beetles, moths and crickets, produce unusually large ejaculates, which in some cases can account for around 10% of their body weight. The study shows that dehydrated females can accept sexual invitations simply to get hold of the water in the seminal fluid.

- Females more prone to brain damage from alcohol abuse
07-25-2007 · EurekAlert!
Alcoholism has traditionally been considered a male disease because there are many more alcoholic males than females. But a study by researchers at Oregon Health & Science University and the Portland Veterans Affairs Medical Center suggests that women are more prone to brain damage from alcohol abuse than men. The study found that female mice are more susceptible to neurotoxic effects of alcohol withdrawal, including significantly increased brain cell death, than male mice.

- A new male-specific gene in algae unveils an origin of male and female
12-18-2006 · EurekAlert!
By studying the genetics of two closely related species of green algae that practice different forms of sexual reproduction, researchers have shed light on one route by which evolution gave rise to reproduction though the joining of distinct sperm and egg cells.

- The precise role of seminal proteins in sustaining post-mating responses in fruit flies
12-17-2007 · EurekAlert!
Successful reproduction is critical to pass genes to the next generation. In sexually reproducing organisms, sperm enter the female with seminal proteins that are vital for fertility. In a new study published on Friday, Dec. 14, 2007 in PLoS Genetics, researchers at Cornell University knocked down the levels of 25 seminal proteins individually in male fruit flies, testing the males' abilities to modulate egg production, sperm storage and release, and the females' post-mating behavior and physiology.

- Brains reflect sex differences
05-10-2007 · EurekAlert!
When male primates tussle and females develop their social skills it leaves a permanent mark -- on their brains. According to research published in the online open access journal BMC Biology, brain structures have developed due to different pressures on males and females to keep up with social or competitive demands.
