Male bats with high testosterone levels have large forearm crusts when females are fertile
Mammalian odors are frequently sexually dimorphic, with males often exhibiting a stronger, or otherwise distinct, odor relative to females, which can be especially useful for nocturnal species with reduced use of vision. Some male bats exhibit intense odors to attract females and reproduce, presumably as a consequence of a high concentration of testosterone. (2020-12-15)

Two genes regulate social dominance
Using the Nobel Prize gene-editing technique, a University of Houston researcher has found that two genes regulate social dominance in cichlid fish and - possibly - humans. (2020-11-10)

In the eye of a stellar cyclone
While on COVID lockdown, a University of Sydney honours student has written a research paper on a star system dubbed one of the ''exotic peacocks of the stellar world''. (2020-10-11)

Zoologists uncover new example of rapid evolution - meet the Sulawesi Babblers
The zoologists, from Trinity College Dublin, have discovered that male and female Sulawesi Babblers (Pellorneum celebense, a species of bird) have evolved to attain different sizes on small islands, and in quick-fire time. They believe this is most likely due to evolutionary pressure favouring such ''dimorphism'' because the birds are able to reduce competition with each other by feeding on different, scarce resources.

Bird genes are multitaskers, say scientists
Scientists from the University of Sheffield have found that although male and female birds have an almost identical set of genes, they function differently in each sex through a mechanism called alternative splicing. (2020-09-25)

Can we really tell male and female dinosaurs apart?
Scientists worldwide have long debated our ability to identify male and female dinosaurs. Now, research led by Queen Mary University of London has shown that despite previous claims of success, it's very difficult to spot differences between the sexes. (2020-05-12)

The mysterious case of the ornamented coot chicks has a surprising explanation
The American coot is a somewhat drab water bird with gray and black feathers and a white beak, common in wetlands throughout North America. Coot chicks, however, sport outrageously bright orange and red feathers, skin, and beaks. A new study explains how the bright coloring of coot chicks fits in with the reproductive strategy of their less colorful parents. (2019-12-30)

Chameleon inspires 'smart skin' that changes color in the sun
Chemists used photonic crystals to develop a flexible smart skin that reacts to heat and sunlight while maintaining a near constant volume. (2019-09-11)

The argument for sexual selection in bacteria
The evolutionary pressure to pass on DNA can produce behavior that otherwise makes no sense in a struggle to survive. Rams bash heads in fights over females; peacocks grow elaborate tail feathers that attract mates and predators alike. Sexual selection can sometimes explain phenomena that natural selection alone cannot. But could bacteria exhibit sexual selection? In an Opinion article published Sept. 4 in the journal Trends in Microbiology, researchers argue that some bacteria might. (2019-09-04)

A study in scarlet Japanese macaques
Researchers assumed that the red faces in Japanese macaques signaled fertility. But new research indicates that it acts more as a 'badge' of social status and is involved in signaling social attributes than fertility. (2019-07-08)

The new great wave
Radical Inkless Technology produces the world's smallest 'Ukiyo-e' and promises to revolutionize how we print. (2019-06-19)

Dive-bombing for love: Male hummingbirds dazzle females with a highly synchronized display
Male Broad-tailed Hummingbirds perform dramatic aerial courtship dives to impress females. In a new study, scientists have shown that diving males closely time key events to produce a burst of signals for the viewer. They synchronize maximal horizontal speed, loud noises generated with their tail feathers, and a display of their iridescent throat-patch (gorget), performed in a mere 300 milliseconds -- roughly the duration of a human blink. (2018-12-18)

Darwin was right: Females prefer sex with good listeners
Almost 150 years after Charles Darwin first proposed a little-known prediction from his theory of sexual selection, researchers have found that male moths with larger antennae are better at detecting female signals. (2017-05-26)

Animal behaviorist looks through the eyes of peafowl
Dr. Jessica Yorzinski uses peafowl to conduct a variety of behavioral studies. Yorzinski looks through the eyes of the birds to actually see what the animals are paying attention to, in this particular case, how males size up their competition. (2017-03-16)

Chemical analysis demonstrates communal nesting in dinosaurs
The reproductive behaviors of birds are some of their most conspicuous and endearing qualities. From the colorful mating display of some birds, like peacocks, to the building of nests by nearly all birds, these are the characters we use to define birds and make them popular study subjects. (2016-10-28)

Unraveling the genes for sexual traits in stag beetles
Scientists have built a gene expression database of a stag beetle and identified genes important for sex determination and differentiation. (2016-07-03)

Deep male voices not so much sexy as intimidating
Male voices are not deeply pitched in order to attract female mates, but instead serve to intimidate the competition, according to a team of researchers studying a wide variety of primates including humans. (2016-05-05)

Peacock tail feathers shake at resonance and hold eyespots still during courtship displays
As male peacocks shake their long feathers in courtship, the iridescent eyespots remain nearly stationary and captivate females, according a study published April 27, 2016, in the open-access journal PLOS ONE. (2016-04-27)

Study of birds' sense of smell reveals important clues for behavior and adaptation

Males of great bustard self-medicate to appear more attractive to females
Males of great bustard consume small doses of poison with a dual purpose: to eliminate intern parasites and, especially, to look healthier and stronger before females, allowing them to achieve a greater reproductive success. A team of researchers from the Spanish National Research Council has now suggested for the first time that this function of self-medication could be a mechanism of sexual selection. The study results are published in the PLOS ONE journal. (2014-10-22)

Best practices in communication for the animal world
Effective communication is not just about the signaler, according to the study, the receiver also needs to assess the signaler efficiently. For instance, one of the most effective strategies from the perspective of female birds is assessing groups of males called leks, where females can assess multiple males in a short period of time. (2014-04-22)

Rules of attraction: Catching a peahen's eye
It's not always easy attracting a female mate and peacocks have resorted to colorful displays to catch a peahen's eye. But what is a peahen looking at in a potential suitor? In a collaborative project between the University of California Davis and Duke University, USA, Jessica Yorzinski finds out using an eye-tracking technique that it's the bottom edge of a peacocks train that catches a peahen's attention most. (2013-07-24)

Best evidence yet that dinosaurs used feathers for courtship
A University of Alberta researcher's examination of fossilized dinosaur tail bones has led to a breakthrough finding: some feathered dinosaurs used tail plumage to attract mates, much like modern-day peacocks and turkeys. (2013-01-04)

Peacock love songs lure eavesdropping females from afar
The distinctive call that male peacocks make right before mating poses a puzzle for scientists. For one, he's already got the girl. What's more, the calls could alert potential predators that an easy meal is near. In a new study, researchers found that the love sounds made by amorous peacocks drew eavesdropping females from afar. Announcing the fact that he's getting a girl could help a male attract additional mates, the researchers say. (2012-12-20)

Biologists turn back the clock to understand evolution of sex differences
Male water striders benefit by mating frequently, females by mating infrequently: both have developed traits to give them the upper hand. The researchers modified a gene involved in the development of antennae in male water striders and found that as the antennae became more elaborate, mating success increased. The study is unusual in that it describes a direct linkage between known forces of selection, evolutionary change morphology, and its underlying genetic basis. (2012-05-03)

A rainbow for the palm of your hand
University at Buffalo engineers have developed a one-step, low-cost method to fabricate a polymer that is rainbow-colored, reflecting many different wavelengths of light when viewed from a single perspective. The colors won't fade with time because they are produced by surface geometry, and not pigment -- the same principle that gives color to the wings of butterflies and feather of peacocks. (2012-02-23)

Fossil moths show their true colors
The brightest hues in nature are produced by tiny patterns in, say, feathers or scales rather than pigments. These so-called (2011-11-15)
