Phyloseminar (Wed 3/16): Making comparative methods as easy as ABC


Brian O’Meara (University of Tennessee, NIMBioS) speaks Wednesday, March 16th at 2pm EST on “Making comparative methods as easy as ABC.” The seminar will take place online and anyone can participate. Instructions on how to join can be found at a


For decades, biologists have addressed evolutionary and ecological questions using measurements of species traits, phylogenies, and an assortment of comparative methods. Unfortunately, while there is a large assortment of these methods, they are still fairly limited and development of new methods is slow. It took seven years between the introduction of using a simple Brownian motion model for looking at trait evolution (Felsenstein, 1985) and the use of this same model for looking at rates of trait evolution (Garland, 1992), and an additional 14 years to more powerful tests using a small modification of the basic model (O’Meara et al., 2006). Still other promising methods are described and even tested but remain unavailable to empiricists because they are not put into software. As a result, the questions empiricists can ask about the world are limited by the research productivity of the few dozen scientists who develop and implement new methods in phylogenetics. We describe a new approach based on Approximate Bayesian Computation and implemented in R that will allow researchers to easily develop their own models for trait evolution without requiring them to have specialized mathematical or computational knowledge.

31, the Chinese government published “China’s National Defense 2010” White Paper,ghd limited edition pink comprehensively expounding China’s defensive national defense policy. Nearly 3 million words in this white paper is divided into preamble and security situation, defense policy, the PLA’s modernization, the use of armed forces and defense mobilization and reserve forces, the military legal system, defense industry, defense spending, military confidence-building, arms control and disarmament, Chapter 10. This is the Chinese government since 1998 Defense White Paper published in the seventh. White further explained the interaction between China and the world. It said that China has a new historical starting point, China’s future destiny and future of the world more closely. The face of common opportunities and challenges,gold ghd classic styler China insists on mutual trust, mutual benefit, equality and cooperation, a new security concept, the fundamental interests of the Chinese people and the common interests of people of the world linked to China’s development and the development of the world linked to China security and world peace link peace and development efforts to promote the building of their own lasting peace, common prosperity and harmonious world. White paper, China is still in the development of important strategic opportunities, overall security environment remains. China faces more diverse and complex security challenges. The face of the complicated security situation, China hold high the peace, development and cooperation, flags, adhere to the comprehensive security,ghd rare leopard print cooperative security, common security concept.

Morning Post, published today, feature articles, “the secret agent pigs Wild World” will open this secret group. In the interest of the temptation,ghd iv styler collection they will “lean” pig farmers to sell directly to the high priority the acquisition of pig farmers to feed the “lean” pigs. Currently, a large number of pig farming and brokers active in every corner of the circulation, they are a kind of group? In the interest of this black chain, what they are in the position? And their regulation is directly related to the future ability to cut off the “lean” of the conveyor chain. The survey found that pig traders and slaughterhouses if not through a broker, often receive less than pigs, and individual investors through a broker and very difficult if you do not find a suitable buyer. The pigs in the pig farmers and buy the intermediary between the general local farmers,ghd pure white styler usually middle-aged men, they both control the swine, pigs customer information on hand to buy another, usually more than to sell drugs, sell feed mainly; some of them have raised pigs, or are still pigs. “Pig broker” a quick mind, silver tongue, well-informed, good at bargaining to facilitate transactions, but also occasionally introduced to the pig farmers in breeding and epidemic prevention knowledge. Each pig has its own agent, “territory”, and pig farmers to maintain close contact with each other at arm’s length relationship between the general will not easily go to other people “territory “ to find businesses. Pig farmers in frequent contact trusted broker. Some villages have also established organizations, ghd new colour collectionlarge-scale income pigs, the pigs become known professional trading village.
