Accepted 18 January, 2011 The aim of this study is to assess genetic polymorphism at two loci in the exon 1 of the kappa-casein gene (CSN3) in Martina Franca donkey breed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis. Martina Franca donkey was derived from the Catalan donkey brought to Apulia at the time of the Spanish rule. This donkey is tall and well built and has good temperament. Both considered loci were found to be monomorphic in the considered population. At CSN3/PstI locus, all the animals were genotyped as AA since no AG and GG animals were found in the population. A similar result was found at CSN3/BseYI locus: all the donkeys were monomorphic and genotyped as AA. As a consequence, only one out of nine possible combined genotype (AAAA) was detected. Key words: Martina Franca donkey, kappa-casein gene (CSN3), gene polymorphism, polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). INTRODUCTION Kappa-casein is the protein that determines the size and (Lenasi et al., 2003). CSN3 is not evolutionarily related to the specific function of milk micelles; its cleavage by the “calcium-sensitive” casein genes, but is physically chymosin is responsible for milk coagulation (Yahyaoui et linked to this gene family, and is functionally important for al., 2003).

    Carbon and Strontium Isotope Stratigraphy of the Permian from Nevada and China: Implications from an Icehouse to Greenhouse Transition

    Carbon and strontium isotope stratigraphy of the Permian from Nevada and China: Implications from an icehouse to greenhouse transition Dissertation Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Kate E. Tierney, M.S. Graduate Program in the School of Earth Sciences The Ohio State University 2010 Dissertation Committee: Matthew R. Saltzman, Advisor William I. Ausich Loren Babcock Stig M. Bergström Ola Ahlqvist Copyright by Kate Elizabeth Tierney 2010 Abstract The Permian is one of the most important intervals of earth history to help us understand the way our climate system works. It is an analog to modern climate because during this interval climate transitioned from an icehouse state (when glaciers existed extending to middle latitudes), to a greenhouse state (when there were no glaciers). This climatic amelioration occurred under conditions very similar to those that exist in modern times, including atmospheric CO2 levels and the presence of plants thriving in the terrestrial system. This analog to the modern system allows us to investigate the mechanisms that cause global warming. Scientist have learned that the distribution of carbon between the oceans, atmosphere and lithosphere plays a large role in determining climate and changes in this distribution can be studied by chemical proxies preserved in the rock record. There are two main ways to change the distribution of carbon between these reservoirs. Organic carbon can be buried or silicate minerals in the terrestrial realm can be weathered. These two mechanisms account for the long term changes in carbon concentrations in the atmosphere, particularly important to climate.

    The Potential for New Donkey Farming Systems to Supply the Growing Demand for Hides

    animals Article The Potential for New Donkey Farming Systems to Supply the Growing Demand for Hides Richard Bennett * and Simone Pfuderer School of Agriculture, Policy and Development, University of Reading, Reading RG6 6AR, UK; [email protected] * Correspondence: [email protected] Received: 18 February 2020; Accepted: 9 April 2020; Published: 20 April 2020 Simple Summary: The demand for donkey hides for gelatin used in Traditional Chinese Medicine, called ejiao, has increased greatly over recent years, resulting in high and rapidly increasing prices. This has put pressure on donkey populations globally and led to theft and illegal trade in donkeys, resulting in concerns for donkey welfare and the livelihoods of those who rely on donkeys. New donkey farming systems have been set up in China in response. We model how quickly these systems may be able to meet the demand for donkey hides. Results show that it will take at least 10–15 years or more for new donkey farming systems to be able to supply the demand for hides. This means that prices of donkeys and donkey hides will continue to increase with continued thefts and illegal trade. This will have further negative impacts on donkey welfare and on the livelihoods of those who rely on donkeys. Chinese ejiao producers will continue to try to source donkey hides from around the world, putting even greater pressure on donkey populations globally. Abstract: The demand for donkey hides for ejiao, a Traditional Chinese Medicine, has resulted in rapidly increasing prices for donkey hides and donkeys. This has put pressure on donkey populations globally and has implications for donkey welfare and the livelihoods of those who rely on donkeys as working animals.

    CONTINENT PDF, EPUB, EBOOK Jim Crace | 176 pages | 04 Jan 2008 | Pan MacMillan | 9780330453318 | English | London, United Kingdom Continent - Wikipedia Geologists theorize that continents move. This theory is called plate tectonics , which holds that the lithosphere , the outermost layer of Earth where continents are , lies on top of a semifluid layer of partially molten magma called the asthenosphere. Convection from the decay of radioactive elements in the mantle causes continental and oceanic plates to move. Pangea is a landmass of the Early Permian to Early Jurassic Periods that incorporated almost all modern landmasses and is thus considered a supercontinent. There is great variation in the sizes of continents; Asia is more than five times as large as Australia. The largest island in the world, Greenland , is only about one-fourth the size of Australia. The continents differ sharply in their degree of compactness. Africa has the most regular coastline and, consequently, the lowest ratio of coastline to total area. Europe is the most irregular and indented and has by far the highest ratio of coastline to total area. The continents are not distributed evenly over the surface of the globe. The distribution of the continental platforms and ocean basins on the surface of the globe and the distribution of the major landform features have long been among the most intriguing problems for scientific investigation and theorizing. Each continent has one of the so-called shield areas that formed 2 billion to 4 billion years ago and is the core of the continent to which the remainder most of the continent has been added.

Dickinson Department of Geosciences, University of Arizona, Tucson, Arizona 85721; email: [email protected] Key Words continental margin, crustal genesis, geologic history, orogen, tectonics ■ Abstract The Cordilleran orogen of western North America is a segment of the Circum-Pacific orogenic belt where subduction of oceanic lithosphere has been under- way along a great circle of the globe since breakup of the supercontinent Pangea began in Triassic time. Early stages of Cordilleran evolution involved Neoproterozoic rifting of the supercontinent Rodinia to trigger miogeoclinal sedimentation along a passive continental margin until Late Devonian time, and overthrusting of oceanic allochthons across the miogeoclinal belt from Late Devonian to Early Triassic time. Subsequent evolution of the Cordilleran arc-trench system was punctuated by tectonic accretion of intraoceanic island arcs that further expanded the Cordilleran continental margin during mid-Mesozoic time, and later produced a Cretaceous batholith belt along the Cordilleran trend. Cenozoic interaction with intra-Pacific seafloor spreading systems fostered transform faulting along the Cordilleran continental margin and promoted incipient rupture of continental crust within the adjacent continental block. INTRODUCTION Geologic analysis of the Cordilleran orogen, forming the western mountain system of North America, raises the following questions: 1.
