-
(Andean Geology, 2016)Two Holocene tephras encountered in outcrops, cores and trenches in bogs, and lake cores in the area around Cochrane, southern Chile, are identified (based on their age, tephra glass color and morphology, mineralogy, and ...
-
(Willey-Blackwell, 2016)South America lost around 52 genera of mammals during a worldwide event known as the Late Quaternary Extinction episode. More than 80% of South American mammals weighing 44 kg succumbed. Analysis of the megafaunal ...
-
(Biomed Central, 2016)Background: Environmental stressors increase the secretion of glucocorticoids that in turn can shorten telomeres via oxidative damage. Modification of telomere length, as a result of adversity faced early in life, can ...
-
(Royal Soc., 2015)Orchids are the most diverse family of angiosperms, with over 25 000 species, more than mammals, birds and reptiles combined. Tests of hypotheses to account for such diversity have been stymied by the lack of a fully ...
-
(Springer, 2016)For polyandrous species where females have sperm storage structures, males develop several strategies to avoid sperm competition and thus to maximize the number of eggs fertilized. On the other hand, females may receive ...
-
(Wiley & Sons, 2015)We present a 16 000-year vegetation and climate reconstruction from pollen and plant macrofossil records obtained at a small alpine lake in South Island, New Zealand (41 degrees S). The expansion of lowland forest taxa ...
-
(American Physical Society, 2015)The localized mode propagation in binary nonlinear kagome ribbons is investigated with the premise to ensure controlled light propagation through photonic lattice media. Particularity of the linear system characterized by ...
-
(Public Library Science, 2015)Some epiphytic Hymenophyllaceae are restricted to lower parts of the host (<60 cm; 10-100 mu mol photons m(-2) s(-1)) in a secondary forest of Southern Chile; other species occupy the whole host height (>= 10 m; max PPFD ...
-
(Springer, 2015)Correlations among and identification of the source volcanoes for over 60 Late Glacial and Holocene tephras preserved in eight lacustrine sediment cores taken from small lakes near Coyhaique, Chile (46 degrees S), were ...
-
(Natl Acad Sciences, 2015)Soil bacteria and fungi play key roles in the functioning of terrestrial ecosystems, yet our understanding of their responses to climate change lags significantly behind that of other organisms. This gap in our understanding ...
-
(Cambridge University Press, 2015)The Santa Marta Foliage-gleaner Automolus rufipectus is one of 19 endemic bird species found in the Sierra Nevada de Santa Marta (SNSM) in northern Colombia but until recently it was considered a sub-species of the Ruddy ...
-
(Springer, 2015)Seagrasses play important ecological roles in shallow coastal ecosystems from tropical to sub-polar seas. Ruppia filifolia (Phil.) Skottsberg is the seagrass with the world's southernmost distribution but with virtually ...
-
(Elsevier, 2015)Disentangling the roles of paleofires and explosive volcanism from climatic drivers of past vegetation change is a subject insufficiently addressed in the paleoecological literature. The coastal region of the Chilo e ...
-
(Oxford Univ Press, 2015)Landscape fragmentation is often a major cause of species extinction as it can affect a wide variety of ecological processes. The impact of fragmentation varies among species depending on many factors, including their ...
-
(Oxford Univ Press, 2015)Galaxias maculatus (Pisces: Galaxiidae) commonly known as "puye" has a disjunct distribution along the Southern Hemisphere including landlocked and migratory populations at latitudes over 30 degrees S in South America, ...
-
(Public Library Science, 2015)Major geologic and climatic changes during the Quaternary exerted a major role in shaping past and contemporary distribution of genetic diversity and structure of aquatic organisms in southern South America. In fact, the ...
-
(Elsevier, 2015)We use macroscopic charcoal and sediment geochemistry analysis of two proximal upper montane lakes located at 42 degrees S in southwest Tasmania, Australia, to test the role of the southern hemisphere westerly winds (SWW) ...
-
(niversidad de Concepción, Facultad de Ciencias Naturales y Oceanográficas, 2015)The genus Carpobrotus was represented on the Chilean flora only by native species C. chilensis. However, we found that the species native of South Africa C. edulis is naturalized in coastal areas. We report it for first ...
-
(Springer, 2014)In this paper, we address the evaluation of algorithms for partial shape retrieval using a large-scale simulated benchmark of partial views which are used as queries. Since the scanning of real objects is a time-consuming ...
-
(Frontiers Research Foundation, 2014)A growing set of observations points to mitochondrial dysfunction, iron accumulation, oxidative damage and chronic inflammation as common pathognomonic signs of a number of neurodegenerative diseases that includes Alzheimer's ...
