(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 ...
-
(Elsevier, 2015)Rufous-collared sparrows (Zonotrichia capensis peruviensis) from valleys in the Atacama Desert of Chile, live in an extremely stable environment, and exhibit overlap in molt and reproduction, with valley-specific differences ...
-
(Springer-Verlag, 2014)Lakes formed in the Aysén region of southern Chile after the retreat of mountain glaciers, established by ~17,900 calendar years before present (cal years BP) or earlier, contain numerous late-glacial and Holocene tephra ...
-
(Elsevier, 2014)We present a detailed record from Lago Lepué to examine vegetation, climate and fire-regime changes since the Last Glacial Maximum (LGM) in central-east Isla Grande de Chiloé (43°S), northwestern Patagonia. Precipitation ...
-
(Elsevier, 2012)Much of the ongoing discussion regarding synchrony or bipolar asynchrony of paleoclimate events has centered on the timing and structure of the last glacial termination in the southern mid- latitudes, in particular the ...
-
(Elsevier, 2012)The genus Drimys is distributed in Chile from semi-arid zones to sub-Antarctic forests; there are three species of this tree, D. andina, D. confertifolia and D. winteri, the latter with varieties chilensis and winteri. ...
-
(Springer, 2012)Colonising populations do not always exhibit founder effects. Common explanations are high levels of immigration and/or reproduction, but few empirical tests have been done. We measured genetic diversity of Nassauvia ...
-
(Elsevier, 2012)The prevailing view in the palaeoclimate literature of the last 20 years is that the Southern Westerly Winds (SWW) were intensified over southern Australia and Tasmania during the warmer-than-present early Holocene (11e8 ...
-
(Springer, 2012)Intraspecific variation in sociality is thought to reflect a trade-off between current fitness benefits and costs that emerge from individuals' decision to join or leave groups. Since those benefits and costs may be ...
-
(Springer, 2012)The Chilean gastropods Crepipatella dilatata and C. fecunda have diVerent development modes: brooding and direct development in C. dilatata and brooding and planktotrophic development in C. fecunda. Unlike many other ...
-
(Blackwell, 2012)Aim Our aim in this study was to document the global biogeographic variation in the effects of soil microbes on the growth of Centaurea solstitialis (yellow starthistle; Asteraceae), a species that has been introduced ...
-
(Springer-Verlag, 2012)The Southern Ocean benthic communities are characterized by their levels of endemism and their diversity of invertebrate brooding species. Overall, biological processes acting within these species remain poorly understood ...
-
(Elsevier, 2012)We present detailed pollen and charcoal records from Lago Pichilafquén (~41°S) to decipher the effects of climate change and varying disturbance regimes on the composition and structure of the vegetation on the Andean ...
-
(Elsevier, 2011)Studies of plant-frugivore interactions are important for identifying the roles that biotic seed vectors play in seed dispersal, and ultimately plant recruitment. In a subandean shrubland of central Chile, 50% of total ...
-
(Springer, 2011-11)A common assumption in behavioral ecology is that the valuation of a resource by consumers depends on the energetic value of the resource itself. Nevertheless, the value of a resource may be relative to the condition of ...
-
(AMER ORNITHOLOGISTS UNION, 2011-01)We assessed how individual foraging preferences and cognitive performance affect foraging bout interval and the flexibility of foraging behavior in the nectarivorous Green-backed Firecrown (Sephanoides sephaniodes). Our ...
-
(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 ...
-
(PERGAMON-ELSEVIER, 2011-01)Antarctica is structured by a narrow and deep continental shelf that sustains a remarkable number of benthic species. The origin of these species and their affinities with the deep-sea fauna that borders the continent shelf ...
-
(2011)We analyzed the statistical distribution of intra-specifi c local abundances for a set North American breeding bird species. We constructed frequency plots for every species and found that they showed long-tail power-law ...
-
(WILEY-BLACKWELL, 2011)P>Paleobotanists have long used models based on leaf size and shape to reconstruct paleoclimate. However, most models incorporate a single variable or use traits that are not physiologically or functionally linked to ...
