While they are thus… occupied… the flowers have any number of methods of depositing pollen upon their waspy exteriors, thereby upping their reproductive odds. Autotomy, the shedding of a body part, reveals the hidden cost of conflict November 15, Animal weapons such as antlers, tusks and limbs specialized for fighting require a large energy expenditure to produce and may cost even more to maintain. Not yet thirty, there are yet decades of research and scientific adventure before her, years of discovery for her and, if we have the gusto and curiosity to follow, for us as well.

We know, or think we do, about the evolutionary tricks of flowers — the colors and patterns and shapes that allure insects to land on and thereby pollinate them, and which have the extra advantage of being interesting enough to humans to provoke mass-scale cultivation. Orangutan mothers found to engage in displaced reference November 15, A pair of researchers with the University of St Andrews has observed orangutan mothers engaging in displaced reference after observation of a perceived threat. New research explains orchids' sexual trickery December 17, A new study reveals the reason why orchids use sexual trickery to lure insect pollinators. Sexually deceptive orchids have evolved the ability to emit scents that mimic the sexual pheromones of female wasps. She risked her social reputation by publicly interceding on the behalf of a cockroach that a staff member was attempting to smoosh. It is an example of an unusually rapid speciation process, and so is of interest to both evolutionary biologists and mainstream botanists. The first thing to know about Weinstein is that she is almost painfully cool. Continuing that separation through the generations results in a hidden speciation process whereby two similar appearing plants no longer reproduce with one another. Among the topics explored are the competing ideas of biologists who use the theory of natural selection when examining possible adaptations such as the ability of orchid flowers to attract special pollinators and those who reject this approach, including creationists as well as the late Stephen Jay Gould. While they are thus… occupied… the flowers have any number of methods of depositing pollen upon their waspy exteriors, thereby upping their reproductive odds. And so it is with a bit of disappointment in our kingdom that I must report, in the dance between our brethren the insects and certain species of orchids, it is the orchids who call the tune. Languages, music, and botany. Solar panels for yeast cell biofactories November 15, Genetically engineered microbes such as bacteria and yeasts have long been used as living factories to produce drugs and fine chemicals. The two new species A. Variance in gut microbiome in Himalayan populations linked to dietary lifestyle November 15, The gut bacteria of four Himalayan populations differ based on their dietary lifestyles, according to a new study by researchers at the Stanford University School of Medicine and their collaborators. Not yet thirty, there are yet decades of research and scientific adventure before her, years of discovery for her and, if we have the gusto and curiosity to follow, for us as well. An Enthusiasm for Orchids: Autotomy, the shedding of a body part, reveals the hidden cost of conflict November 15, Animal weapons such as antlers, tusks and limbs specialized for fighting require a large energy expenditure to produce and may cost even more to maintain. But there exist a special group of flowers who take that game to a whole other level — the sexually deceptive orchids, and among the vanguard of those studying the tricks of their trade is year-old Australian botanist Alyssa Weinstein. And then, when it came time to go to university, she followed a diverse course of study to feed all of her many interests instead of accepting the common advice to find a specialty and dig fervently into it. More recently, researchers have started to combine bacteria with semiconductor technology Sex and Deception in Plant Evolution John Alcock Abstract This book reviews a variety of evolutionary themes and uses the small terrestrial orchids of Australia to introduce and illustrate these themes. Recommended for you Drop your weapons! By mutating subtly varying types of emitted pheromones, different orchids can attract entirely different species of wasps, meaning that even though two orchids may look the same, they might be serviced by two different wasp species, so they may not end up exchanging genetic information with each other. In addition, the book outlines the ability of evolutionary biologists to trace the origin and subsequent modification of complex traits like the extraordinarily unusual flowers of certain orchids. More This book reviews a variety of evolutionary themes and uses the small terrestrial orchids of Australia to introduce and illustrate these themes. In their paper published in the journal Science Advances, Adriano

  1. British botanists find unknown 'warty' orchid species February 5, British botanists have found a previously unrecorded orchid in the mountains of Cambodia, they said Thursday, ahead of a major orchid show at London's Kew Gardens. But there exist a special group of flowers who take that game to a whole other level — the sexually deceptive orchids, and among the vanguard of those studying the tricks of their trade is year-old Australian botanist Alyssa Weinstein.

  2. New maps hint at how electric fish got their big brains November 15, Helmet-heads of the freshwater fish world, African mormyrid fishes are known for having a brain-to-body size ratio that is similar to humans.

  3. Among the topics explored are the competing ideas of biologists who use the theory of natural selection when examining possible adaptations such as the ability of orchid flowers to attract special pollinators and those who reject this approach, including creationists as well as the late Stephen Jay Gould.

  4. Finding ways to conserve these species naturally leads to larger questions of environmental protection, which Weinstein is addressing by opening more lines of communication between the scientific community and the population at large. Not yet thirty, there are yet decades of research and scientific adventure before her, years of discovery for her and, if we have the gusto and curiosity to follow, for us as well.
