Dispersal is a major driver of the latitudinal diversity gradient of Carnivora

AimUnderstanding the relative contribution of diversification rates (speciation and extinction) and dispersal in the formation of the latitudinal diversity gradient - the decrease in species richness with increasing latitude - is a main goal of biogeography. The mammalian order Carnivora, which comprises 286 species, displays the traditional latitudinal diversity gradient seen in almost all mammalian orders. Yet the processes driving high species richness in the tropics may be fundamentally different in this group from that in other mammalian groups. Indeed, a recent study suggested that in Carnivora, unlike in all other major mammalian orders, net diversification rates are not higher in the tropics than in temperate regions. Our goal was thus to understand the reasons why there are more species of Carnivora in the tropics. LocationWorld-wide. MethodsWe reconstructed the biogeographical history of Carnivora using a time-calibrated phylogeny of the clade comprising all terrestrial species and dispersal-extinction-cladogenesis models. We also analysed a fossil dataset of carnivoran genera to examine how the latitudinal distribution of Carnivora varied through time. ResultsOur biogeographical analyses suggest that Carnivora originated in the East Palaearctic (i.e. Central Asia, China) in the early Palaeogene. Multiple independent lineages dispersed to low latitudes following three main paths: toward Africa, toward India/Southeast Asia and toward South America via the Bering Strait. These dispersal events were probably associated with local extinctions at high latitudes. Fossil data corroborate a high-latitude origin of the group, followed by late dispersal events toward lower latitudes in the Neogene. Main conclusionsUnlike most other mammalian orders, which originated and diversified at low latitudes and dispersed out of the tropics', Carnivora originated at high latitudes, and subsequently dispersed southward. Our study provides an example of combining phylogenetic and fossil data to understand the generation and maintenance of global-scale geographical variations in species richness.

The People's Republic of China and her relations with the countries of the association of Southeast Asian nations : 1969-1975

Phe Ihesis examines the evolution of the -policies of the People fs Jtenublie of China towards J?hail°nd, PTal ysia, Singapore, Iidonesia pad the Philip-pines, organised in the Association of Southeast Asian Nations from 1969 to 1975• 2ze first central point of this study is an *ir sumption that the foreign relations of The People's Tepublic of Chi la Towards Southeast ^sia have been motivated by a dynamic interplay of t^o main factors: (1) Farxist-Leninist ideology and ICao J^e-tung Ph^ught, which dictate to China to behave as a revolutionary Dover vhich must assist the insurgent movements in the area in their strug fle to overthrow the local governments; (2) national interest, vhich demands of China to safeguard the southern flank of her territory bordering on Southerst 'sia through Friendly relations, trade and ot*»er conventional inrtniments of diplomacy. hile the tvo main motive factors are nuTually antagonistic and exclusivet the Chinere leaders are nevertheless at te mi ting to oring them iirco a coherent policy under Mao's theory of tve {hniity of op-nosites," vhich believes that it is -possible to reconcile these co-posing tendencies into a dynamic enuibrium through vhich both opnosites could be promoted at the same time although not to the same extent* la other words, the Chinese leaders conceive the dynamic equilibrium as a continuum between them in a mix in which one or the other orientation predominates in different •periods* Bins we might see China1 s conduct motivated in one period by mostly ideological considerations at the expense of the staire-to-state relations, then ve might see her policy in the middle of the continuum and suf ering from immo bill sine and just muddling through, or finally ?fe might see her emphasising friendly ties at the expense of support of revolutionary movements at the other extreme -point of the spectrum* !fhe mechanism vhich enables Peking to move from one pole to the other of the spectrum is activated by the following elementsJ (1) the result of an internal power struggle within the leadership in Peking between ideologically radical and moderate elements, which enables the victorious faction to initiate nev policies; (2) Peking's assessment of the changing intentions and capabilities of the major powers in the area; (3) internal changes within the countries of the area and the changing attitudes of their governments towards China; (4) changing fortunes of revolutionary movements operating in the area* 'Phe second major point of this study is an assertion that while China's conduct toward Southeast *lsia after her foundation in 1949 was primarily based upon ideological considerations, the beginning of the seventies saw the national interest reasserting itself as the leading motive factor* Thus China talks with her neighbours in Southeast asia in terms of relevance of fllong historical ties," casting herself into the role of a benevolent "older brother11 who is entitled to reopect and deference in exchange for patronage and protection* Hence the traditional echoes of the past are emerging ever stronger and influencing her postures towards the region, while the open support to revolutionary moevments is underplayed at the moment.

Phylogénie et biogéographie du genre Bauhinia s.l. (Leguminosae)

Bauhinia s.l. est le plus vaste genre de la tribu des Cercideae (Ceasalpinioideae, Leguminoseae), avec plus de 300 espèces. Il présente une distribution pantropicale et une grande variabilité morphologique. Ces deux caractéristiques ont limité les études taxonomiques sur le genre complet, résultant en plusieurs études taxonomiques de certains groupes seulement. En 1987, Wunderlin et al. proposent une vaste révision taxonomique de la tribu des Cercideae, basée sur des données morphologiques, et divisent le genre Bauhinia en quatre sous-genres. En 2005, Lewis et Forest publient une nouvelle classification préliminaire basée sur des données moléculaires, mais sur un échantillonnage taxonomique restreint. Leurs conclusions remettent en question le monophylétisme du genre Bauhinia et suggèrent plutôt la reconnaissance de huit genres au sein du grade Bauhinia s.l. Afin de vérifier les hypothèses de Lewis et Forest, et obtenir une vision plus claire de l’histroire de Bauhinia s.l., nous avons séquencé deux régions chloroplastiques (trnL-trnF et matK-trnK) et deux régions nucléaires (Leafy et Legcyc) pour un vaste échantillonnage représentatif des Cercideae. Une première phylogénie de la tribu a tout d’abord été réalisée à partir des séquences de trnL-trnF seulement et a confirmé le non-monoplylétisme de Bauhinia s.l., avec l’inclusion du genre Brenierea, traditionnellement reconnu comme genre frère de Bauhinia s.l. Afin de ne pas limiter notre vision de l’histoire évolutive des Cercideae à un seul type de données moléculaires et à une seule région, une nouvelle série d’analyse a été effectuée, incluant toutes les séquences chloroplastiques et nucléaires. Une phylogénie individuelle a été reconstruite pour chacune des régions du génome, et un arbre d’espèce ainsi qu’un arbre de supermatrice ont été reconstruits. Bien que certaines contradictions apparaissent entre les phylogénies, les grandes lignes de l’histoire des Cercideae ont été résolues. Bauhinia s.l. est divisée en deux lignées : les groupes Phanera et Bauhinia. Le groupe Bauhinia est constitué des genres Bauhinia s.s., Piliostigma et Brenierea. Le groupe Phanera est constitué des genres Gigasiphon, Tylosema, Lysiphyllum, Barklya, Phanera et Schnella. Les genres Cercis, Adenolobus et Griffonia sont les groupes-frères du clade Bauhinia s.l. Au minimum un événement de duplication de Legcyc a été mis en évidence pour la totalité de la tribu des Cercideae, excepté Cercis, mais plusieurs évènements sont suggérés à la fois par Legcyc et Leafy. Finalement, la datation et la reconstruction des aires ancestrales de la tribu ont été effectuées. La tribu est datée de 49,7 Ma et est originaire des régions tempérées de l’hémisphère nord, probablement autour de la mer de Thétys. La tribu s’est ensuite dispersée vers les régions tropicales sèches de l’Afrique, où la séparation des groupes Bauhinia et Phanera a eu lieu. Ces deux groupes se sont ensuite dispersés en parallèle vers l’Asie du sud-est au début du Miocène. À la même période, une dispersion depuis l’Afrique de Bauhinia s.s. a permis la diversification des espèces américaines de ce genre, alors que le genre Schnella (seul genre américain du groupe Phanera) est passé par l’Australie afin de rejoindre le continent américain. Cette dispersion vers l’Australie sera également à l’origine des genres Lysiphyllum et Barklya

El crecimiento económico de corea del sur y sus posibilidades de alterar el equilibrio en Asia-Pacífico

El interés de esta monografía es analizar el crecimiento económico de Corea del Sur y sus posibilidades de alterar el equilibrio en la región de Asia-Pacífico. A partir de los conceptos de poder duro y equilibrio de poder propuestos por Joseph Nye y Ernst Haas, se examinan los principales hitos del proceso de desarrollo nacional y se determina en qué sentido el incremento del poder duro nacional le permite a este país posicionarse como una potencia regional en ascenso. Así mismo, se evalúan los procesos de liderazgo regional de China y Japón que impiden a Corea del Sur alterar sustancialmente el equilibrio de poder en esta región del mundo.

Dime cómo me percibes y te diré quién soy: Estados Unidos y su idea de la política exterior China en la década de 1950

La década de 1950 fue determinante en el establecimiento y póstumo desarrollo del sistema de política exterior de la República Popular China. Al respecto, es de vital importancia realizar un análisis exhaustivo sobre esta primera etapa en donde actores externos a la nación tuvieron un papel determinante. Se busca, entonces, analizar la incidencia que tuvo el discurso de Estados Unidos en la política exterior China a través de un profundo análisis cualitativo que tendrá como base elementos propios de la historiografía. Mediante aproximaciones constructivistas, se pretende demostrar que las creencias pre-existentes de ambos actores (así como la intersubjetividad entre los mismos), determinó la identidad construida a través de la percepción mutua. Lo anterior, impulsó las relaciones predominantemente agresivas entre Estados Unidos y la China Maoísta de principios de la Guerra Fría.

The ship as symbol in the prehistory of Scandinavia and south-east Asia

The ship is the dominant element in the visual culture of the South Scandinavian Bronze Age, appearing in several different media, including rock carvings, decorated metalwork and above-ground monuments. Discussion has divided between those scholars who interpret this imagery in terms of long-distance exchange networks and those who emphasize its more local significance, including its deployment in mortuary ritual. A strikingly similar system is identified in Southeast Asia and part of Melanesia and can be interpreted through archaeological and ethnographic sources, but in this case there is no need to distinguish between 'practical' and 'symbolic' interpretations of the depictions of ships. This paper summarizes the evidence from this region and suggests that it can offer a fruitful source of comparison for archaeologists working in northern Europe.

Syndromic approach to arboviral diagnostics for global travelers as a basis for infectious disease surveillance

Background Arboviruses have overlapping geographical distributions and can cause symptoms that coincide with more common infections. Therefore, arbovirus infections are often neglected by travel diagnostics. Here, we assessed the potential of syndrome-based approaches for diagnosis and surveillance of neglected arboviral diseases in returning travelers. Method To map the patients high at risk of missed clinical arboviral infections we compared the quantity of all arboviral diagnostic requests by physicians in the Netherlands, from 2009 through 2013, with a literature-based assessment of the travelers’ likely exposure to an arbovirus. Results 2153 patients, with travel and clinical history were evaluated. The diagnostic assay for dengue virus (DENV) was the most commonly requested (86%). Of travelers returning from Southeast Asia with symptoms compatible with chikungunya virus (CHIKV), only 55% were tested. For travelers in Europe, arbovirus diagnostics were rarely requested. Over all, diagnostics for most arboviruses were requested only on severe clinical presentation. Conclusion Travel destination and syndrome were used inconsistently for triage of diagnostics, likely resulting in vast under-diagnosis of arboviral infections of public health significance. This study shows the need for more awareness among physicians and standardization of syndromic diagnostic algorithms

Where were the monsoon regions and arid zones in Asia prior to the Tibetan Plateau uplift?

The impact of the Tibetan Plateau uplift on the Asian monsoons and inland arid climates is an important but also controversial question in studies of paleoenvironmental change during the Cenozoic. In order to achieve a good understanding of the background for the formation of the Asian monsoons and arid environments, it is necessary to know the characteristics of the distribution of monsoon regions and arid zones in Asia before the plateau uplift. In this study, we discuss in detail the patterns of distribution of the Asian monsoon and arid regions before the plateau uplift on the basis of modeling results without topography from a global coupled atmosphere–ocean general circulation model, compare our results with previous simulation studies and available biogeological data, and review the uncertainties in the current knowledge. Based on what we know at the moment, tropical monsoon climates existed south of 20°N in South and Southeast Asia before the plateau uplift, while the East Asian monsoon was entirely absent in the extratropics. These tropical monsoons mainly resulted from the seasonal shifts of the Inter-Tropical Convergence Zone. There may have been a quasi-monsoon region in central-southern Siberia. Most of the arid regions in the Asian continent were limited to the latitudes of 20–40°N, corresponding to the range of the subtropical high pressure year-around. In the meantime, the present-day arid regions located in the relatively high latitudes in Central Asia were most likely absent before the plateau uplift. The main results from the above modeling analyses are qualitatively consistent with the available biogeological data. These results highlight the importance of the uplift of the Tibetan Plateau in the Cenozoic evolution of the Asian climate pattern of dry–wet conditions. Future studies should be focused on effects of the changes in land–sea distribution and atmospheric CO2 concentrations before and after the plateau uplift, and also on cross-comparisons between numerical simulations and geological evidence, so that a comprehensive understanding of the evolution of the Cenozoic paleoenvironments in Asia can be achieved.

An exploratory study on how to improve the economy of American Samoa

Deep in the South Pacific region about 2,300 miles southwest of the Hawaiian islands1 lies a United States territory that many Americans have never heard of nor known anything about. However, some famous Americans such as Troy Polamalu of the Pittsburgh Steelers, semi retired professional wrestler Dwayne “The Rock” Johnson, and Hawaii Congresswoman Tulsi Gabbard have genealogical roots there. More importantly, many of the Territory’s sons and daughters have served and lost their lives for the United States flag and the cause of freedom around the world. This place is called American Samoa, a collection of seven islands that if glued together would have a total landmass of approximately 76 square miles, just a tad bigger than the capital city of the United States. According to the United States Census Bureau, there were 55,519 residents of American Samoa in 2010.1 The majority of them are ethnic Samoans, a Polynesian sect that traces its history back to early migrants from Southeast Asia who settled the islands around 1500 B.C.2 3 The climate is warm all year long and the forests along the mountains are ripe with vegetation. The main island is Tutuila with its beautiful and coveted landlocked harbor that was used as a coaling station by the United States naval ships during World War II. In fact, it was the Pago Pago Harbor that diminished the impact of the 2009 Tsunami that devastated the Samoan islands by channeling the waters of the Pacific Ocean towards the end of the harbor instead of flooding many other villages surrounding the Pago Pago Bay area. Lives and property were destroyed near the end of the Harbor but it could have been worse for the entire Bay area. Locally grown foods include coconut, taro, banana, guava, sugar cane, papaya, yam, pineapple, and breadfruit. It is completely surrounded by the Pacific Ocean from which the locals obtain a variety of seafood. There is a popular saying in Samoa that goes, “In Samoa, it is impossible to starve 1 American Samoa Department of Commerce, 2012 Statistical Yearbook, http://www.doc.as/wpcontent/uploads/2011/06/2012-Statistical-Yearbook-1.pdf 2 U.S. Census Bureau News, U.S. Census Bureau Releases 2010 Census Population Counts for American Samoa, http://www.census.gov/2010census/news/releases/operations/cb11-cn177.html (Aug. 24, 2011). 3 3 J. Robert Shaffer, American Samoa: 100 Years Under the United States Flag (Honolulu, Hawaii: Island Heritage Publishing, 2000), 34. 4 because people live off of the land’s and the ocean’s abundant resources.” To the west of American Samoa lies a larger group of four islands that make up the Sovereign State of Samoa, which became independent from New Zealand in 1962. Samoa and American Samoa share the same language, culture, and religion but are divided by government and political systems. The focus of this study will be on American Samoa, which became a United States territory in 1900 when the principal chiefs of Tutuila (the largest island in American Samoa) ceded the islands to the United States.

Indonesien in der ASEAN des 21. Jahrhunderts: eine Analyse des indonesischen Einflusspotenzials in der Assoziation südostasiatischer Staaten

Die Geschichte und Entwicklung der ASEAN und Indonesiens im Zeitraum von 1967rnbis ins frühe 21. Jahrhundert sind eng miteinander verknüpft. Um der Frage nachrndem indonesischen Einflusspotenzial in der ASEAN im 21. Jahrhundert nachgehenrnund dann einen Ausblick auf die Zukunft der Rolle Indonesiens in der ASEAN gebenrnzu können, bedarf es zunächst einer Analyse dessen, was in der Vergangenheitrndazu führte, dass Indonesien in der Region als primus inter pares wahrgenommenrnwurde, und der Rolle, die Indonesien im Rahmen der Erweiterung und Vertiefung der ASEAN bisher spielte. So ist der Fokus der Arbeit auf vier Phasen gerichtet: (1) die Gründungszeit der ASEAN sowie die Etablierung Indonesiens als einer der einflussreichsten Mitgliedstaaten; (2) die asiatische Finanzkrise, die nicht nur der Entwicklung der ASEAN als erstem Erfolgsmodell regionaler Kooperation in Südostasien vorläufig ein Ende setzte, sondern auch Indonesien in große wirtschaftliche wie politische Turbulenzen trieb; (3) die überregionale Erweiterung der ASEAN und der Beginn der politischen Transformation in Indonesien sowie (4) die Vertiefung der ASEAN-Kooperation und die Stabilisierung Indonesiens als demokratischer Akteur. rnFür alle vier Phasen werden das materielle Machtprofil, die institutionellen Verknüpfungen sowie ideelle Faktoren des Einflusspotenzials Indonesiens untersucht, um sich einer Antwort auf die Frage zu nähern, über welches Einflusspotenzial Indonesien in der ASEAN des 21. Jahrhunderts verfügt. Die Analyse bringt zutage, dass es Indonesien vor der Asienkrise trotz erheblicherrnEntwicklungsrückstände möglich war, gestaltenden Einfluss auf die ASEANrnauszuüben und an regionaler Bedeutsamkeit sowie Einflusspotenzial in der ASEANrnzu gewinnen. Trotz deutlich erkennbarer Entwicklungsfortschritte ist dasrngegenwärtige Indonesien jedoch nicht in der Lage, sein Einflusspotenzial in derrnASEAN zu steigern, sich als relevanter Akteur zu etablieren und erneut einernSchlüsselrolle einzunehmen. Die Akteure der ASEAN folgen nicht wie einst denrnIdeen Indonesiens, und die regionale Fremdwahrnehmung Indonesiens wird ganzrnerheblich vom derzeitigen politischen und sozialen Wertesystem beeinflusst, mit dem sich kein anderer ASEAN-Staat ohne Einschränkung identifizieren kann. rnDie Erkenntnisse der Arbeit führen letztlich zu dem Fazit, dass es aktuell kaum Raum für eine Steigerung des indonesishen Einflusse innerhalb des ostasiatischenrnRegionalismus gibt. Für die Gegenwart und vielleicht die kommenden Dekaden mussrnfür Indonesien attestiert werden, dass es sich mit der Rolle als Teilnehmer in den ASEAN-Prozessen begnügen muss.

Liberation as Revolutionary Praxis: Rethinking Buddhism Materialism

While it is only in recent decades that scholars have begun to reconsider and problematize Buddhist conceptions of “freedom” and “agency,” the thought traditions of Asian Buddhism have for many centuries struggled with questions related to the issue of “liberation”—along with its fundamental ontological, epistemological and ethical implications. With the development of Marxist thought in the mid to late nineteenth century, a new paradigm for thinking about freedom in relation to history, identity and social change found its way to Asia, and confronted traditional religious interpretations of freedom as well as competing Western ones. In the past century, several attempts have been made—in India, southeast Asia, China and Japan—to bring together Marxist and Buddhist worldviews, with only moderate success (both at the level of theory and practice). This paper analyzes both the possibilities and problems of a “Buddhist materialism” constructed along Marxian lines, by focusing in particular on Buddhist and Marxist conceptions of “liberation.” By utilizing the theoretical work of Japanese “radical Buddhist” Seno’o Girō, I argue that the root of the tension lies with conceptions of selfhood and agency—but that, contrary to expectations, a strong case can be made for convergence between Buddhist and Marxian perspectives on these issues, as both traditions ultimately seek a resolution of existential determination in response to alienation. Along the way, I discuss the work of Marx, Engels, Gramsci, Lukàcs, Sartre, and Richard Rorty in relation to aspects of traditional (particularly East Asian Mahāyāna) Buddhist thought.
