They are one of the most highly prized delicacies in the culinary world, but now scientists have discovered that black truffles are locked in a gender war for reproduction. The research, published in New Phytologist as the truffle season begins, represents a breakthrough in the understanding of truffle cultivation and distribution. The teams, led by Dr Francesco Paolocci and Dr Andrea Rubini from the CNR Plant Genetics Institute in Perugia and by Dr Francis Martin from INRA in Nancy, carried...

A forthcoming issue of the Journal of Marriage and Family states that children today are less likely to be born into a "traditional" family structure, defined as two biological married parents. Growing numbers of children in the United States experience multiple family living arrangements during childhood. How these transitions affect the individual child's well-being needs to be fully addressed by researchers and policymakers alike. This article fully reviews the existing research from the...

Sexual conflict is not only a human phenomenon. Scientists at the University of Gothenburg have shown that females of the rough periwinkle conceal their gender identity in order to avoid excessive copulation. The females of most species of snail excrete a substance in their mucous trails that enables males to find them more easily, since they can distinguish between trails from females and those from other males. The males follow the mucous trails laid down by females in order to find a...

Male bedbugs are known to be very unfussy when it comes to mating, mounting any well-fed bug they can see - regardless of age or gender. Researchers writing in the open access journal BMC Biology have discovered how immature bedbug nymphs, who would be harmed by the traumatic insemination technique practiced by the males, release alarm pheromones to deter this unwanted attention. Vincent Harraca, from Lund University, Sweden, worked with a team of researchers to stage encounters between males...

Courtship calls tell penguin females how fat a male is and what kind of father he'll be How does a female penguin choose a mate? Courtship calls help females decide which males are likely to be devoted dads, says a study in the journal Behaviour. Antarctic penguins come on land for just a few short months each summer to breed and raise their chicks. Raising a family in the coldest place on earth is no small feat. Adelie penguins pull it off by tag-team parenting, the researchers explained....

A new study by researchers in Germany, which appears in the Wednesday edition of the journal Biology Letters, provides new insight into the unusual sex life of spiders. Scientists Klaas W. Welke and Jutta M. Schneider of the University of Hamburg's Zoological Institute and Museum raised a handful of common European spiders from eggs that they discovered in a nearby meadow. The spiders were fed fruit flies until they reached adulthood, and Welke and Schneider observed their mating patterns....

Mothers win the genetic tug of war by producing more sons with larger fathers and more daughters with smaller fathers "Be faithful in small things because it is in them that your strength lies." Mother Teresa's words echo throughout the world. They ring particularly true in the biological kingdom among brown anole lizards, as evidenced in research detailed in the April 2 edition of the journal Science. Dartmouth researchers Ryan Calsbeek and Bob Cox study male and female brown anole lizards...

The brains of males and females, and how they use them, may be far more different than previously thought, at least in the fruit fly Drosophila melanogaster, according to research funded by the Wellcome Trust. In a paper published today in the journal Nature Neuroscience, researchers from the University of Glasgow and the University of Oxford, have shown that the gene known as 'doublesex' (dsx), which determines the shape and structure of the male and female body in the fruit fly, also...

Researchers at the California Institute of Technology (Caltech) and the University of California, San Diego (UCSD) have discovered that injecting a simple hormone into leeches creates a novel way to study how hormones and the nervous system work together to produce species-specific reproductive behavior. A paper describing the work appears in the March 11 online edition of the journal Current Biology. Daniel Wagenaar, Broad Senior Research Fellow in Brain Circuitry at Caltech and first author...

UC researcher finds that when it comes to hooking up with the opposite sex, genital complexities do matter. Charles Darwin spent eight years studying barnacles and their genitalia. In much less time than that, University of Cincinnati evolutionary biologist Michal Polak (and co-author Arash Rashed, now at the University of California, Berkeley) have confirmed one of Darwin's theories: that genitalia complexities in some male species have developed because they assist the male in "holding her...

Stegodyphus lineatus is the only European species belonging to the spider genus Stegodyphus. The males of this species are up to 12 millimeters long, while the females are up to 15 millimeters long. The coloration can range from whitish to almost black. In the majority of individuals, the opisthosoma is whitish with two broad black longitudinal stripes. The males and females look similar, but the male is usually richer in contrast and has a bulbous forehead. The species name is in...

The Greek Tortoise, Testudo graeca, is one of four European member of the Testudinidae family of tortoises. The other members of the family are Herman's Tortoise, Marginated Tortoise, and Horsfield's Tortoise. There are six noticeable differences between males and females of the Greek Tortoise. Males have a longer tail that tapers to an even point. The anal cavity opening is farther from the base of the tail on the male. The male's underbelly is somewhat curved, while females have a flat...
