With luck, this piece of the evolutionary puzzle may soon fit into place!&nbsp;&nbsp;<strong>Image left:&nbsp;</strong><em>Callistomys pictus</em></p><hr><h1>Associate Curator and Chair Thorsten Lumbsch, Postdoctoral Research Scientist Steve Leavitt (both Botany) and coworkers published&nbsp;a paper, entitled “<a href="http://www.sciencedirect.com/science/article/pii/S1055790312003703">Mult... phylogeny of the lichen-forming fungal genus <em>Melanohalea</em>&nbsp;(Parmeliaceae, Ascomycota): Insights on diversity, distributions, and a comparison of species tree and concatenated topologies</a>,” in the journal&nbsp;<em>Molecular Phylogenetics and Evolution </em>investigating diversity in an important lichen-forming fungal genus that occurs throughout the Northern Hemisphere.&nbsp; This study is the result of broad, international collaborative efforts and includes collections from 26 countries across four continents and provides an important perspective on species distributions within this common genus.&nbsp; In some cases, species are shown to have broad distributions spanning multiple continents, while other species appear to be restricted to small geographic regions.&nbsp; An important component of this study is the documentation of multiple previously unrecognized species in temperate regions of Europe, western North America, and South America.&nbsp; Collections representing these new species are now incorporated into the mycology collection at The Field Museum.&nbsp; These collections&nbsp;provide an important baseline for ongoing studies documenting species’ responses to global climatic change.&nbsp; Overall, this study demonstrates the synergistic value of effective international collaborations in understanding and documenting biological diversity on this planet. &nbsp; <strong>See Header Image</strong>: <em>Melanoalea elegantula in the Lone Peak Wilderness Area, Utah, USA.

Their work provides a new twist to understanding evolutionary tempo and mode—rates and patterns of change over geologic time—that are mostly revealed by studying the fossil record. Paleontologists measure parts of the skeletal fossil remains of once-living organisms that they believe best represent the morphology, or form, of those organisms.&nbsp; They then analyze the variation in these traits through successive layers of rock that were laid down over longs spans of geologic time in order to determine the tempo and mode of species evolution.&nbsp; The new study is based on data taken from hundreds of sequences of fossil samples previously reported in the scientific literature, but uses model selection methods available only in the last several years.&nbsp; The researchers compared models describing different modes of change, namely stasis, random change, and directional change, to each fossil series and found that different traits generally showed different, conflicting evolutionary modes within the same species.&nbsp; Many kinds of life were represented, including mammals, fish, mollusks, arthropods, and single-celled organisms.&nbsp; This large comparative study validates the ubiquity of mosaic evolution.&nbsp; At the same time, it also raises questions about the evidence for different evolutionary modes, since the great majority of previous studies that quantify evolutionary stasis, punctuated equilibrium, and gradual or “random” patterns in the fossil record are based on measurements of single traits, not on combined analyses of many traits.&nbsp; Their results have far-reaching implications because these canonical patterns, and the broader topic of evolutionary modes, are taught in just about every major textbook on evolutionary biology and on paleontology.&nbsp; Further research will be required to establish the underlying processes driving the patterns of mosaic evolution and fossil species change.&nbsp; Nonetheless, the study is an excellent example of an emerging revolution in scientific inquiry as new techniques are used to breathe new life into old data.</p><hr><p><img alt="" class="wysiwyg-left" src="http://fieldmuseum.org/sites/default/files/BJLS_fig_0.png" title="" typeof="foaf:Image" wysiwyg="1">In December, Associate Curator and Chair Thorsten Lumbsch and Postdoctoral Research Scientist Steve Leavitt (both Botany), along with colleagues Pradeep Divakar (Universidad Complutense de Madrid, Spain) and Ted Esslinger (North Dakota State University, USA), published a paper in the <em>Biological Journal of the Linnean Society</em> entitled “<a href="http://onlinelibrary.wiley.com/doi/10.1111/j.1095-8312.2012.01978.x/abst... divergence, phenotypically cryptic lineages, and contrasting distribution patterns in common lichen-forming fungi (Ascomycota: Parmeliaceae)</a>.”&nbsp; They provide evidence supporting previously unrecognized species within a common, widespread, and relatively well-known group of camouflage lichens (<em>Melanelixia</em>).&nbsp; The results suggest that the dispersal ability and establishment success of closely related species may be species-specific, even in species with similar reproductive strategies.&nbsp; The Field Museum now maintains the majority of the <em>Melanelixia </em>collections made in conjunction with this study in the Mycology Collection in the Department of Botany.&nbsp; These collections include the only identified material representing the previously unrecognized species found in this study.&nbsp; This study provides an important perspective on diversity and biogeography in common lichen-forming, and the collections made in conjunction with this study provide a valuable resource for ongoing lichenological research.&nbsp; <strong>Image left: </strong><em>“Claudogram” of a camouflage lichens species tree</em></p><hr><h1>Curator Chapurukha Kusimba (Anthropology) attended an international conference held at the Guangdong Provincial Museum in Guangzhou, China.&nbsp; The conference entitled: Ancient Maritime Trade in Chinese Porcelain featured anthropologists, archaeologists, and art historians from Hong Kong, Macau, and China.&nbsp; Chap was the only representative from North America.&nbsp; In his paper “Ancient and Contemporary Connections between China and East Africa,” Chap argued that the continuous occurrence of Chinese trade porcelain in dateable archaeological contexts at several key sites in East Africa from the Tang through Qing Dynasties (ca. AD 756–1908) pointed to the long, productive relationship between China and East Africa.&nbsp; This relationship is now under critical scholarly scrutiny by Chap and his colleagues at Sun Yat-Sen University in Guangzhou, China.&nbsp; A proposal to support this joint collaborative research effort is being considered by the Chinese Science Commission.</h1><hr><p>Associate Curator and Chair Ryan Williams (Anthropology) presented “Crossing the Western Altiplano” at the American Anthropological Association meetings in San Francisco on November 18.&nbsp; His paper elaborated on the reasons the ancient Tiwanaku civilization was able to sustain such a substantial colony in the western valley of Moquegua, 300 km away from the Tiwanaku capital city.&nbsp; Ryan and Research Associate Ben Vining used satellite imaging and geographic information systems modeling of ancient roads to argue that the corridor connecting Moquegua and Tiwanaku was more than twice as rich in ecological resources, especially green pasturage and lacustrine resources, than any other pathway between Tiwanaku and the western valleys.&nbsp; Pasturage and lakes were necessary to sustaining human settlement and the large herds of llamas that were the primary form of transport in the ancient Andes.&nbsp; Thus, the scale of colonial expansion was dependent not only on resources in the zone of colonization, but also on resources along the road that connected dependent colonies to their capital cities.</p><hr><p>Associate Curator Bill Parkinson (Anthropology) presented a lecture at the University of Wisconsin-Madison on November 16.&nbsp; The talk, entitled “The Social Dynamics of Early Agricultural Villages in Southeastern Europe,” was presented to the Department of Anthropology at UW-Madison, and focused on his ongoing multidisciplinary archaeological research projects in Greece and Hungary, where Bill and his colleagues are investigating how small early agricultural villages evolved into larger, more complex, proto-urban settlements.&nbsp;</p><hr><p><img alt="" class="wysiwyg-left" src="http://fieldmuseum.org/sites/default/files/Suphrodytes_0.jpg" title="" typeof="foaf:Image" wysiwyg="1">Research Assistant Gracen Brilmyer (Zoology/Insects) co-authored a paper with&nbsp;Johannes Bergsten (Sweden Museum of Natural History), Alex Crampton-Platt (Natural History Museum), and Anders N.

The lecture focused on mammal preparation for museum collections, including skinning, pickling, and the use of the Dermestid beetle colony.&nbsp; Anna also discussed the FMNH laboratory facilities and collection management techniques that have been refined over the past century, and are currently a model</p><p>for other natural history institutions.&nbsp; The lecture was enthusiastically received and Cambridge museum personnel are developing new plans for their labs to handle more specimen preparation in the future, based in part on Anna’s lecture and interaction with museum staff.&nbsp;
