Camels GET THE HUMP on rivals<br />

UQ research has found when it comes to<br />

camels, staying cool may be the key to<br />

reproductive success.<br />

Emeritus Pr<strong>of</strong>essor Gordon Grigg, from<br />

UQ’s School <strong>of</strong> Biological Sciences, and<br />

a team <strong>of</strong> colleagues working in Central<br />

Australia, have found male camels have an<br />

ability to drop their body temperature which<br />

may help them last longer in rutting displays.<br />

“Rutting involves very energetic daily<br />

display ‘fighting’ during which bulls contest<br />

ownership <strong>of</strong> a herd <strong>of</strong> females,” Pr<strong>of</strong>essor<br />

Grigg said.<br />

“By starting each day cooler, a bull can<br />

postpone heat stress, compete for longer,<br />

win more contests and potentially sire more<br />

<strong>of</strong>fspring.”<br />

He said the ability <strong>of</strong> camels to drop<br />

body temperature in the mornings, invoking<br />

hypothermia, was once thought to be only a<br />

mechanism for conserving water in very hot<br />

and dry conditions.<br />

“But what we saw cannot be for saving<br />

water as we saw it only in winter, only in bulls<br />

during rut and they had water freely available<br />

and used it routinely,” he said.<br />

“So we speculate that by lowering their<br />

minimum temperature each morning during<br />

rut, bulls increase their chance <strong>of</strong> winning a<br />

harem.<br />

“By starting the day cool, a bull<br />

will enhance his capacity to store heat<br />

generated by the strenuous activity, thus<br />

prolonging the onset <strong>of</strong> heat stress.<br />

“A bull that can sustain a contest<br />

for longer is more likely to win it and, so,<br />

control a herd <strong>of</strong> females and get more<br />

matings.<br />

“That is, the daily hypothermias we<br />

observed could have a direct bearing on<br />

reproductive success.”<br />

Pr<strong>of</strong>essor Grigg said the rutting<br />

habits <strong>of</strong> male camels were fascinating<br />

as competing bulls performed elaborate,<br />

ritualised and intense competitive<br />

behaviour including posing and strutting<br />

side-by-side, inflating and exposing the<br />

dulaa (a sac-like extension <strong>of</strong> the palate),<br />

jostling, exhibiting flehmen (curling the<br />

upper lip), running together and fighting.<br />

Pr<strong>of</strong>essor Grigg was joined by<br />

Jürgen Heuke and Birgit Dörges from the<br />

<strong>University</strong> <strong>of</strong> Braunschweig, veterinarian<br />

Jocelyn Coventry, cattleman Alex<br />

Coppock and School <strong>of</strong> Biological Science<br />

colleagues Lyn Beard and Simon Blomberg<br />

for the project. Their findings have been<br />

published online in scientific journal Biology<br />

Letters.<br />

A national survey conducted by UQ researchers<br />

has found that the majority <strong>of</strong> same-sex<br />

attracted Australians reported marriage to<br />

be their personal preference for relationship<br />

recognition.<br />

The findings dispel the myth that most<br />

same-sex couples do not wish to marry or are<br />

content with de facto status, and form<br />

part <strong>of</strong> the larger Not So Private Lives<br />

survey.<br />

The study is the first national<br />

survey to investigate the<br />

relationship recognition<br />

preferences <strong>of</strong> same-sex<br />

attracted Australians since the<br />

introduction <strong>of</strong> de facto status<br />

for same-sex couples at a<br />

Federal level.<br />

Findings showed that<br />

the majority (54.1 percent) <strong>of</strong><br />

same-sex attracted participants<br />

selected marriage as their personal<br />

choice and close to 80 percent felt<br />

marriage should be an option for<br />

same-sex couples in Australia.<br />

Researcher Sharon Dane,<br />

from UQ’s School <strong>of</strong> Psychology,<br />

said marriage was still the<br />

personal choice <strong>of</strong> the majority,<br />

irrespective <strong>of</strong> the current legal<br />

status <strong>of</strong> participants’ same-sex<br />

relationships.<br />

“Importantly, the majority<br />

showing a personal preference for marriage<br />

was even more substantial among those<br />

currently in a state or municipal civil partnership<br />

or an overseas civil union,” Ms Dane said.<br />

“This suggests that alternatives to marriage,<br />

such as civil unions, can be important for those<br />

who do not wish to marry but are clearly not a<br />

substitute for the many who do.”<br />

Botanical cologne A bottler<br />

stewart gould<br />

Ever wanted to bottle the fresh “green”<br />

aroma <strong>of</strong> a forest? UQ researcher Dr Nick<br />

Lavidis has done just that, launching a<br />

new “eau de grass” spray.<br />

Serenascent, which smells<br />

like cut grass and claims to make<br />

the wearer happier and less<br />

stressed, was launched by the<br />

State Treasurer and Minister for<br />

Employment and Economic<br />

Development, Andrew Fraser.<br />

Mr Fraser congratulated<br />

Dr Lavidis and retired<br />

pharmacologist Associate<br />

Pr<strong>of</strong>essor Rosemarie Einstein<br />

for their seven-year research project.<br />

Dr Lavidis said he first had the idea for<br />

Serenascent on a trip to Yosemite National<br />

Park in America more than 20 years ago.<br />

“Three days in the park felt like a threemonth<br />

holiday,” he said.<br />

“I didn’t realise at the time that it was the<br />

actual combination <strong>of</strong> feel-good chemicals<br />

released by the pine trees, the lush vegetation<br />

and the cut grass that made me feel so relaxed.<br />

“Years later my neighbour commented on<br />

the wonderful smell <strong>of</strong> cut grass after I had<br />

mowed the lawn and it all clicked into place.”<br />

Dr Lavidis said the aroma <strong>of</strong> Serenascent<br />

worked directly on the brain, in particular the<br />

emotional and memory parts known as the<br />

amygdala and the hippocampus.<br />

“These two areas form the limbic system<br />

that controls the sympathetic nervous<br />

system,” he said.<br />

“They are responsible for the ‘flight or<br />

fight’ response and the endocrine system.<br />

The new spray appears to regulate these<br />

areas.”<br />

Serenascent can be puchased online.<br />
