(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)Engineered tissues are highly limited by poor vascularization in vivo, leading to hypoxia. In order to overcome this challenge, we propose the use of photosynthetic biomaterials to provide oxygen. Since photosynthesis is ...
-
(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 ...
-
(SOCIEDAD BIOLGIA CHILE, 2006-03)Photosynthesis of Colobanthus quitensis and mesoclimatic conditions of air temperature and light intensity during the growing season were investigated at 2,650 in ill the central Chilean Andes. Oil three typical days of ...
-
(UNIV CHICAGO PRESS, 2008-04)The endemic southern South American genus Hamadryas (Ranunculaceae), consisting of five species, has been regarded as closely related to or part of Ranunculus s.l. (tribe Ranunculeae) based on morphological observations. ...
-
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2006-12)Penalized likelihood analysis of previously published chloroplast DNA (cpDNA) ndhF sequences suggests that the central-southern Andean genus Chaetanthera diverged ca. 16.5 million years (my) ago, well before the uplift of ...
-
(PERGAMON-ELSEVIER, 2011-01)Endemic to Antarctic ecosystems, the limpet Nacella (Patinigera) concinna (Strebel, 1908) is an abundant and dominant marine benthic invertebrate of the intertidal and shallow subtidal zone. In order to examine the ...
-
(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 ...
-
Phylogeography of Oligoryzomys longicaudatus (Rodentia : Sigmodontinae) in temperate South America (ALLIANCE COMMUNICATIONS GROUP DIVISION ALLEN PRESS, 2005-02)Phylogeographic relationships were evaluated at the intraspecific level using nucleotide sequence data from the mitochondrial cytochrome b gene of representative specimens of "colilargo" (Oligoryzomys longicaudatus) from ...

(2006)Se presentan 61 nuevos registros de plantas introducidas para el Parque Nacional Torres del Paine (49°21’-51°08’S y 73°07’-74°52’O), región de Magallanes, con una superficie de 181.414 ha. Se encontraron 85 ...
-
(JOHN WILEY & SONS LTD, 2005-07)Precipitation in northern Chile is controlled by two great wind belts-the southern westerlies over the southern Atacama and points south (>24 degrees S) and the tropical easterlies over the northern and central Atacama ...
-
(INST ARCTIC ALPINE RES, 2006-11)Low temperatures, short growing seasons, and strong winds, which constrain the abundance and activity of insect pollinators, characterize alpine ecosystems. In northern hemisphere alpine environments, the reproductive ...
-
(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 ...
-
(Frontiersin Plant Science, 2015)Polyols are enzymatically-produced plant compounds which can act as compatible solutes during periods of abiotic stress. Nicotinamide adenine dinucleotide+-dependent SORBITOL DEHYDROGENASE (SDH, E. C. 1.1.1.14) from ...
-
(SPRINGER, 2008-04)Invasive species can increase fire frequency and intensity, generating favorable conditions for their self-perpetuation. Mediterranean south-central Chile may be especially prone to the effects of invasive species on fire ...
-
(BLACKWELL, 2006-01)In alpine habitats, positive interactions among plants tend to increase with elevation as a result of altitudinal increase in environmental harshness. However, in mountains located in arid zones, lower elevations are also ...
-
(Nature, 2022)Although mitochondrial DNA has been widely used in phylogeography, evidence has emerged that factors such as climate, food availability, and environmental pressures that produce high levels of stress can exert a strong ...
-
(Springer, 2020)Shifts in species distributions are among the observed consequences of climate change, forcing species to follow suitable environmental conditions. Using species distribution models (SDMs), we aimed at predicting trends ...
