    Description: The vast majority of Mesozoic and early Cenozoic metatherian mammals (extinct relatives of modern marsupials) are known only from partial jaws or isolated teeth, which give insight into their probable diets and phylogenetic relationships but little else. The few skulls known are generally crushed, incomplete or both, and associated postcranial material is extremely rare. Here we report the discovery of an exceptionally large number of almost undistorted, nearly complete skulls and skeletons of a stem-metatherian, Pucadelphys andinus, in the early Palaeocene epoch of Tiupampa in Bolivia. These give an unprecedented glimpse into early metatherian morphology, evolutionary relationships and, especially, ecology. The remains of 35 individuals have been collected, with 22 of these represented by nearly complete skulls and associated postcrania. These individuals were probably buried in a single catastrophic event, and so almost certainly belong to the same population. The preservation of multiple adult, sub-adult and juvenile individuals in close proximity (〈1 m(2)) is indicative of gregarious social behaviour or at least a high degree of social tolerance and frequent interaction. Such behaviour is unknown in living didelphids, which are highly solitary and have been regarded, perhaps wrongly, as the most generalized living marsupials. The Tiupampan P. andinus population also exhibits strong sexual dimorphism, which, in combination with gregariousness, suggests strong male-male competition and polygyny. Our study shows that social interactions occurred in metatherians as early as the basal Palaeocene and that solitary behaviour may not be plesiomorphic for Metatheria as a whole.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ladeveze, Sandrine -- de Muizon, Christian -- Beck, Robin M D -- Germain, Damien -- Cespedes-Paz, Ricardo -- England -- Nature. 2011 Jun 2;474(7349):83-6. doi: 10.1038/nature09987.

    Description: Coupled climate-carbon cycle models suggest that Amazon forests are vulnerable to both long- and short-term droughts, but satellite observations showed a large-scale photosynthetic green-up in intact evergreen forests of the Amazon in response to a short, intense drought in 2005. These findings suggest that Amazon forests, although threatened by human-caused deforestation and fire and possibly by more severe long-term droughts, may be more resilient to climate changes than ecosystem models assume.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Saleska, Scott R -- Didan, Kamel -- Huete, Alfredo R -- da Rocha, Humberto R -- New York, N.Y. -- Science. 2007 Oct 26;318(5850):612.

    Description: A comparative analysis of 23 populations of the Brazil nut tree (Bertholletia excelsa) across the Brazilian, Peruvian, and Bolivian Amazon shows that the history and intensity of Brazil nut exploitation are major determinants of population size structure. Populations subjected to persistent levels of harvest lack juvenile trees less than 60 centimeters in diameter at breast height; only populations with a history of either light or recent exploitation contain large numbers of juvenile trees. A harvesting model confirms that intensive exploitation levels over the past century are such that juvenile recruitment is insufficient to maintain populations over the long term. Without management, intensively harvested populations will succumb to a process of senescence and demographic collapse, threatening this cornerstone of the Amazonian extractive economy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Peres, Carlos A -- Baider, Claudia -- Zuidema, Pieter A -- Wadt, Lucia H O -- Kainer, Karen A -- Gomes-Silva, Daisy A P -- Salomao, Rafael P -- Simoes, Luciana L -- Franciosi, Eduardo R N -- Cornejo Valverde, Fernando -- Gribel, Rogerio -- Shepard, Glenn H Jr -- Kanashiro, Milton -- Coventry, Peter -- Yu, Douglas W -- Watkinson, Andrew R -- Freckleton, Robert P -- New York, N.Y. -- Science. 2003 Dec 19;302(5653):2112-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Ecology, Evolution and Conservation, School of Environmental Sciences, University of East Anglia, Norwich NR4 7TJ, UK.

    Description: Mitochondrial DNA sequences isolated from ancient dog remains from Latin America and Alaska showed that native American dogs originated from multiple Old World lineages of dogs that accompanied late Pleistocene humans across the Bering Strait. One clade of dog sequences was unique to the New World, which is consistent with a period of geographic isolation. This unique clade was absent from a large sample of modern dogs, which implies that European colonists systematically discouraged the breeding of native American dogs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Leonard, Jennifer A -- Wayne, Robert K -- Wheeler, Jane -- Valadez, Raul -- Guillen, Sonia -- Vila, Carles -- New York, N.Y. -- Science. 2002 Nov 22;298(5598):1613-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Organismic Biology, Ecology and Evolution, University of California, Los Angeles, CA 90095-1606, USA.

    Description: Long sediment cores recovered from the deep portions of Lake Titicaca are used to reconstruct the precipitation history of tropical South America for the past 25,000 years. Lake Titicaca was a deep, fresh, and continuously overflowing lake during the last glacial stage, from before 25,000 to 15,000 calibrated years before the present (cal yr B.P.), signifying that during the last glacial maximum (LGM), the Altiplano of Bolivia and Peru and much of the Amazon basin were wetter than today. The LGM in this part of the Andes is dated at 21,000 cal yr B.P., approximately coincident with the global LGM. Maximum aridity and lowest lake level occurred in the early and middle Holocene (8000 to 5500 cal yr B.P.) during a time of low summer insolation. Today, rising levels of Lake Titicaca and wet conditions in Amazonia are correlated with anomalously cold sea-surface temperatures in the northern equatorial Atlantic. Likewise, during the deglacial and Holocene periods, there were several millennial-scale wet phases on the Altiplano and in Amazonia that coincided with anomalously cold periods in the equatorial and high-latitude North Atlantic, such as the Younger Dryas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baker, P A -- Seltzer, G O -- Fritz, S C -- Dunbar, R B -- Grove, M J -- Tapia, P M -- Cross, S L -- Rowe, H D -- Broda, J P -- New York, N.Y. -- Science. 2001 Jan 26;291(5504):640-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Duke University, Division of Earth and Ocean Sciences, Durham, NC 27708, USA. pbaker@geo.duke.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11158674" target="_blank"〉PubMed〈/a〉

    Description: Amazonian rain forest-savanna boundaries are highly sensitive to climatic change and may also play an important role in rain forest speciation. However, their dynamics over millennial time scales are poorly understood. Here, we present late Quaternary pollen records from the southern margin of Amazonia, which show that the humid evergreen rain forests of eastern Bolivia have been expanding southward over the past 3000 years and that their present-day limit represents the southernmost extent of Amazonian rain forest over at least the past 50,000 years. This rain forest expansion is attributed to increased seasonal latitudinal migration of the Intertropical Convergence Zone, which can in turn be explained by Milankovitch astronomic forcing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mayle, F E -- Burbridge, R -- Killeen, T J -- New York, N.Y. -- Science. 2000 Dec 22;290(5500):2291-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geography, University of Leicester, Leicester LE1 7RH, UK. fem1@leicester.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11125139" target="_blank"〉PubMed〈/a〉
