Shen et al. BMC Evolutionary Biology 2010, 10:132 http://www.biomedcentral.com/1471-2148/10/132 RESEARCH ARTICLE Open Access AResearch mitogenomic article perspective on the ancient, rapid radiation in the Galliformes with an emphasis on the Phasianidae Yong-Yi Shen1,2,3, Lu Liang1,2,3, Yan-Bo Sun1,2,3, Bi-Song Yue4, Xiao-Jun Yang1, Robert W Murphy1,5 and Ya- Ping Zhang*1,2 Abstract Background: The Galliformes is a well-known and widely distributed Order in Aves. The phylogenetic relationships of galliform birds, especially the turkeys, grouse, chickens, quails, and pheasants, have been studied intensively, likely because of their close association with humans. Despite extensive studies, convergent morphological evolution and rapid radiation have resulted in conflicting hypotheses of phylogenetic relationships. Many internal nodes have remained ambiguous. Results: We analyzed the complete mitochondrial (mt) genomes from 34 galliform species, including 14 new mt genomes and 20 published mt genomes, and obtained a single, robust tree. Most of the internal branches were relatively short and the terminal branches long suggesting an ancient, rapid radiation. The Megapodiidae formed the sister group to all other galliforms, followed in sequence by the Cracidae, Odontophoridae and Numididae. The remaining clade included the Phasianidae, Tetraonidae and Meleagrididae. The genus Arborophila was the sister group of the remaining taxa followed by Polyplectron. This was followed by two major clades: ((((Gallus, Bambusicola) Francolinus) (Coturnix, Alectoris)) Pavo) and (((((((Chrysolophus, Phasianus) Lophura) Syrmaticus) Perdix) Pucrasia) (Meleagris, Bonasa)) ((Lophophorus, Tetraophasis) Tragopan))). Conclusions: The traditional hypothesis of monophyletic lineages of pheasants, partridges, peafowls and tragopans was not supported in this study. -
Introducing the Emperor of Antarctica
Read the passage. Then answer the question below. Introducing the Emperor of Antarctica A plump five-foot figure, wearing what looks like a tuxedo, walks across a frozen landscape. Suddenly, the figure drops to its belly and paddles its limbs as if swimming. Sound strange? Actually, it is the emperor of Antarctica…the emperor penguin, that is. One could easily argue that the emperor penguin is the king of survival. These amazing creatures live in the harshest climate on earth. Temperatures in Antarctica regularly reach –60°C and blizzards can last for days. But in this frigid world, the emperors swim, play, breed, and raise their chicks. Although emperor penguins are birds, they are unable to take flight. Rather, they do their “flying” in the water. Their flipper-like wings and sleek bodies make them expert swimmers. Emperors are able to dive deeper than any other bird and can stay under water for up to 22 minutes. The emperors are so at home in the water that young penguins enter the water when they are just six months old. Like many birds, the emperor penguins migrate during the winter. This migration, however, is very different. Each year, as winter approaches, the penguins leave the comfort—and food supply—of the ocean to begin a 70-mile journey across the ice. Walking single file, the penguins waddle along for days, flopping to their bellies and pushing themselves along with their flippers when their feet get tired. Along the way, colonies of penguins meet up with other colonies all headed for the same place—the safety of their breeding grounds. -

The new taxon is recovered from the Lower Jurassic Fengjiahe Formation of Shuangbai County, Chuxiong Yi Autonomous Prefecture, Yunnan Province, and is represented by a partial cranium. Shuangbaisaurus is unique in possessing parasagittal crests along the orbital dorsal rims. It is also distinguishable from the other two lager-bodied parasagittal crested Early Jurassic theropods (Dilophosaurus and Sinosaurus) by a unique combination of features, such as higher than long premaxillary body, elevated ventral edge of the premaxilla, and small upper temporal fenestra. Comparative morphological study indicates that “Dilophosaurus” sinensis could potentially be assigned to Sinosaurus, but probably not to the type species. The discovery of Shuangbaisaurus will help elucidate the evolution of basal theropods, especially the role of various bony cranial ornamentations had played in the differentiation of early theropods. -

Looking for Loons
Looking For Loons What would a trip to the northwoods be without the sight of a loon feeding in a quiet back bay or the echo of a tremolo call in the twilight? While visitors to the north can find loons on everything from mailboxes to coffee mugs, t-shirts, and placemats, finding and observing real birds is often more challenging. Here are some tips on how to observe loons while minimizing your impacts on nesting and chick rearing. Loon Calendar - When to View Loons The season for loon observation in the Upper Midwest begins shortly after ice-out, usually in late April or early May. When the loons arrive in spring, their first activities are typically to establish their territories and their pair bonds. Loons are territorial birds, defending an area where they feed, nest and raise their young. Territorial behaviors include aggressive running and splashing, and an upright dance across the water– termed the penguin dance. Male loons defend their territories with the yodel vocalization. Loon pairs enhance their bond using behaviors such as bill dipping, paired swimming, nest building, and copulation. Spring is a fascinating time to observe loons but it is also a critical time in the birds' life cycle. People can easily disturb loons and cause nest abandonment. While loons with a history of nesting on more developed lakes can acclimate to human activities, loons on remote lakes can be very sensitive to human presence. If you are observing loons in the spring, stay 200 feet away when possible and view them with binoculars or a spotting scope. -
Grounded Birds in New Zealand
Flightless Grounded Birds in New Zealand An 8th Grade Research Paper By Nathaniel Roth Hilltown Cooperative Charter Public School June 2014 1 More than half of the birds in New Zealand either can’t fly, can only partially fly, or don’t like to fly. (Te Ara) This is a fact. Although only sixteen species in New Zealand are technically flightless, with another sixteen that are extinct (TerraNature), a majority of more than 170 bird species will not fly unless their lives are threatened, or not even then. This is surprising, since birds are usually known for flying. A flightless bird is a bird that cannot fly, such as the wellknown ostrich and emu, not to mention penguins. The two main islands southeast of Australia that make up New Zealand have an unusually diverse population of these birds. I am personally very interested in New Zealand and know a lot about it because my mother was born there, and I still have family there. I was very intrigued by these birds in particular, and how different they are from most of the world’s birds. I asked myself, why New Zealand? What made this tiny little country have so many birds that can’t fly, while in the rest of the world, hardly any live in one place? My research has informed me that the population and diversity of flightless birds here is so large because it has been isolated for so long from other land masses. Almost no mammals, and no land predators, lived there in the millions of years after it split from the Australian continent, so flying birds didn’t have as much of an advantage during this time. -

The future is uncertain for Antarctica, with many possibilities – some more plausible, others more preferable. Indeed, the region and its governance regime may be reaching (or may have reached) a crossroads moment as a result of a series of challenges, including the changing Antarctic climate and environment, increasing human activity, shifting values among Antarctic states and a low-cost, somewhat benign governance regime (the Antarctic Treaty System). Within this context there are a number of interdependent drivers that are likely to influence Antarctica’s future over, say, 25 years: global environmental and socio-economic developments; Antarctic governance; Antarctic research, including national Antarctic programme operations; and Antarctic tourism. The research presented here involved a thorough examination of Antarctic literature on current Antarctic developments and challenges, and an assessment of global trends. -
Cranial Anatomy of Allosaurus Jimmadseni, a New Species from the Lower Part of the Morrison Formation (Upper Jurassic) of Western North America

Loewen3,4,* 1 Dinosaur National Monument (retired), Jensen, UT, USA 2 Independent Researcher, Jensen, UT, USA 3 Natural History Museum of Utah, University of Utah, Salt Lake City, UT, USA 4 Department of Geology and Geophysics, University of Utah, Salt Lake City, UT, USA * These authors contributed equally to this work. ABSTRACT Allosaurus is one of the best known theropod dinosaurs from the Jurassic and a crucial taxon in phylogenetic analyses. On the basis of an in-depth, firsthand study of the bulk of Allosaurus specimens housed in North American institutions, we describe here a new theropod dinosaur from the Upper Jurassic Morrison Formation of Western North America, Allosaurus jimmadseni sp. nov., based upon a remarkably complete articulated skeleton and skull and a second specimen with an articulated skull and associated skeleton. The present study also assigns several other specimens to this new species, Allosaurus jimmadseni, which is characterized by a number of autapomorphies present on the dermal skull roof and additional characters present in the postcrania. In particular, whereas the ventral margin of the jugal of Allosaurus fragilis has pronounced sigmoidal convexity, the ventral margin is virtually straight in Allosaurus jimmadseni. The paired nasals of Allosaurus jimmadseni possess bilateral, blade-like crests along the lateral margin, forming a pronounced nasolacrimal crest that is absent in Allosaurus fragilis.
