Sequential reduction of UV-B radiation in the field alters the pigmentation of an Antarctic leafy liverwort

first_imgUV-B radiation (280–315 nm), incident on the leafy liverwort Cephaloziella varians growing at Rothera Point on the Western Antarctic Peninsula, was manipulated in late austral spring 1998 by screens consisting of a novel combination of Plexiglas panes and polyester sheets. The screens transmitted approximately 79, 68, 48, 41 and 31% of daily UV-B radiation dose. Plants from under and outside the screens were sampled seven times over 35 days. Correlative analyses indicated that concentrations of an anthocyanin-like pigment located in leaf tips were positively associated with UV-B transmission at the last two samplings, that concentrations of total chlorophylls were negatively associated with UV-B transmission at the final sampling, and that those of UV-B screening pigments were positively correlated with transmission at three intermediate samplings. Plants exposed to low UV-B transmission levels were visibly greener than those exposed to high transmission levels after approximately 23 days. The closest relationships between the treatment and concentrations of UV-B screening pigments were associated with increased ambient biologically weighted UV-B dose received by plants in the 5.5 h before each sampling, which coincided with the passage of the ozone hole over Rothera Point. As C. varians emerged from melting snow and ice, concentrations of the anthocyanin-like pigment and chlorophyll respectively increased and decreased faster in plants exposed to high transmission levels of UV-B, relative to those exposed to low UV-B transmission levels.last_img read more

Researchers take closer look at serrated teeth of ancient predator

first_imgGorgonopsians were the apex predators of their day 250 million years ago. These forerunners to mammals evolved from cat-sized animals to bear-sized hunters during the middle and late Permian Period. But what made them truly formidable was their teeth.Gorgonopsians were the first saber-toothed animals. Their canines extended up to about 5 inches and were serrated, allowing them to tear into prey the way a diner uses a steak knife to cut meat. That dental feature helped make them dominant carnivores before they went extinct. A new Harvard-led study, published Wednesday in Biology Letters, bolsters that fearsome reputation by taking a closer look at the construction of those teeth.The research shows that the serrations were made of a complex arrangement of tissues called enamel and dentine. These tissues folded along the cutting edges of the blade-like teeth to form a series of tightly packed serrations. This type of complex tooth serration was thought to be unique to the masters of carnivory — the therapod dinosaurs, including the legendary Tyrannosaurus rex. This new analysis, however, shows dinosaurs and gorgonopsians developed this specific cutting tooth independently. Not only that, the study shows that gorgonopsians, a lineage more related to humans than dinosaurs, actually had them first.“Our finding shows that it happened more on the mammal line as opposed to the reptile line and that it happened much earlier than we previously thought, since these animals are much older than the theropod dinosaurs,” said Megan Whitney, a postdoctoral researcher in the FAS Department of Organismic and Evolutionary Biology. “What we’re seeing is this really cool instance of convergent evolution.”,The finding is significant because of the timing and complexity involved. The fact that this happened in gorgonopsians means it occurred early in amniote evolution. Amniotes include reptiles and mammal lineages.“It’s a very complicated way to build a serration because it involves two different tissues making really complicated folds,” Whitney said. “Typically, we associate that with time, right? The more time you have for evolution to take place, the more we think there’s the ability to evolve complicated traits. What we’re finding here is that actually these animals early in amniote evolution were able to evolve a very complicated and specialized structure.”Whitney worked on the study with Aaron LeBlanc of King’s College in London, Ashley Reynolds from the University of Toronto, and Kirstin Brink from the University of Manitoba in Canada.The project started because of a mistake. The group was cutting up fossilized teeth to study the tissues at the microscopic level. Working on one of the gorgonopsian canines, Whitney accidently cut through a serration. One of the co-authors examined it on a whim and realized it looked like a theropod tooth. The group thought they were onto something and decided to dive deeper.A complete sabre-toothed canine from a gorgonopsian from Zambia. This specimen includes both the crown (top) and root (bottom) of the tooth. Photo credit: Megan WhitneyTeeth with serrations are known as ziphodont dentitions. The team compared the ones in gorgonopsians to carnivores who also had them. The comparison group included a theropod dinosaur and other synapsids. The synapsid animals include both modern mammals and their predecessors, like the gorgonopsians.The gorgonopsian teeth appeared similar to other synapsid teeth, but under a microscope looked more dinosaur-like. For instance, one of the comparison synapsids was Smilodon fatalis, better known as the saber-toothed tiger. While both Smilodon and gorgonopsians had saber teeth with serrations, those serrations were different and so were the way they used them. Smilodon’s serrations were made entirely of a thick enamel. This helped lead to different feeding strategies. Gorgonopsians tore flesh with their long canines, while Smilodon mainly used them to dispatch prey.Comparing gorgonopsians with the therapod dinosaur, the scientists saw they had the same interdental folds made of enamel and dentine. This setup helps strengthen the teeth and helps them last longer in the mouth, making the animal a more efficient eater. It’s reflected in the puncture-and-pull feeding style that allowed them to cut through prey more easily.“These animals have all evolved serrations, but the microscopic ways in which they do so may differ,” said Reynolds, a graduate student. Ultimately, it shows “there’s more than one way to skin a cat, [or in this case] a cat’s prey.”The researchers have spent the past decade trying to understand how complex features of teeth have evolved in ancient species. While findings like this are satisfying, they believe there is a lot more to be discovered.“It shows us that there’s a lot of complicated traits that have evolved earlier than we thought,” Whitney said. “Broadly, the group is really interested in looking at these hidden features and trying to shed light on a more complicated evolutionary history in the evolution of teeth than I think we’ve previously recognized.”This research was supported with funding from the National Science Foundation, the Natural Sciences and Engineering Research Council of Canada, the National Geographic Society, the Field Museum of Natural History, and the IDP Foundation, Inc.last_img read more

Did anyone actually want a waffle taco?

first_img 6SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr No small degree of consumer research went into Taco Bell’s decision to roll out a line of breakfast menu items. Jumping into the fast food breakfast fracas last year, Taco Bell lobbed a spicy shot over the bows of more established competitors like McDonald’s, Sonic and Burger King.So, yes, if you now so choose, you can order a Waffle Taco for breakfast. Or an A.M. Crunchwrap. Or even a Grande Scrambler Burrito.The question is … should you? Or, more precisely, do you want to?An easy mistake for a company to make is trying to be all things to all people. Rather than identifying a market niche (the thing you’re best at) and a target audience (the type of people you best serve) these misguided attempts try to be a little bit of something to everybody. The results are typically less than spectacular. Like salad flavored Jell-O, purple Ketchup and Coors water.Taco Bell had a pretty good thing going in the minds of many consumers – cheap, fast, pseudo Mexican food. It was a mainstay of my college years (including way too many “make a run for the border” dormitory jokes). Grape flavored Jell-O, red Ketchup and Coors Beer were working just fine, too. Like those examples, jumping into the breakfast food arena is a potential blunder. Why try to be a breakfast food provider to a massive audience relatively happy with what you’ve already got? continue reading »last_img read more
