(2010)In the present study, we compared Trypanosoma cruzi infection in four native mammals from a hyperendemic area of Chagas disease in Chile for two different periods to assess the occurrence of interannual variation (1999– 2000 ...
-
(Elsevier, 2018-06)The most critical question for climate research is no longer about the problem, but about how to facilitate the transformative changes necessary to avoid catastrophic climate-induced change. Addressing this question, ...
-
(Elsevier, 2018)A molecular dynamics study of the effect of a single B2–CuZr precipitate on the mechanical properties of Cu50Zr50 metallic glass nanowires is presented. Four different samples are considered: three with a 2, 4 and 6 nm ...
-
(2009-01)We describe the tensor products of two irreducible linear complex representations of the group G = GL(3, F q) in terms of induced representations by linear characters of maximal torii and also in terms of classical ...
-
(Springer, 2018)Life in saline environments represents a major physiological challenge for birds, particularly for passerines that lack nasal salt glands and hence are forced to live in environments that do not contain salty resources. ...
-
Testing for functional convergence of temperate rainforest tree assemblages in Chile and New Zealand (Taylor & Francis, 2016)An important tenet of biogeography and comparative ecology is that disjunct assemblages in similar physical environments are functionally more similar to each other than to assemblages from other environments. Temperate ...
-
(Springer, 2013)Nectar robbing may have an indirect negative effect on plant reproduction by discouraging legitimate pollinator species from visiting robbed flowers. In this study, we set up a 2 9 2 factorial design with nectar-robbing ...
-
(Wiley, 2018-06)Heterozygosity has been positively associated with fitness and population survival. However, the relationship between heterozygosity and adaptive phenotypic plasticity (i.e., plasticity which results in fitness homeostasis ...
-
(Springer, 2020)A dynamic thermal time model (DTTM) has been developed to predict cold-hardiness in dormant grapevine buds, which uses daily mean temperatures as the only input variable. However, it has been recently reported that ...
-
(Ecological Society of America, 2017)The niche variation hypothesis (NVH) predicts that populations with broader niches should exhibit greater between- individual diet variation or individual specialization (IS) relative to populations with narrower niches. ...
-
(Elsevier Ireland Ltd, 2013)Codons expanded by a silent position (quadruplet or tetracodons) may solve the conundrum that at life's origins, the weak tricodon-anticodon interactions could not promote translation in the absence of complex ribosomes. ...
-
(2013)Background: Odontoblasts are specialized cells that form dentin and they are believed to be sensors for tooth pain. Transforming growth factor-β1 (TGF-β1), a pro-inflammatory cytokine expressed early in odontoblasts, plays ...

-
(Copernicus Gesellschaft MBH, 2021)Glaciers and ice caps are thinning and retreating along the entire Andes ridge, and drivers of this mass loss vary between the different climate zones. The southern part of the Andes (Wet Andes) has the highest abundance ...
-
(Pergamon Press Ltd., 1992-03-26)1. 2C-B [2-(4-bromo-2,5-dimethoxyphenyl)ethylamine] elicits concentration-dependent contraetion of the rat thoracic aorta (apparent pD2 = 4.55). The maximal contraction (Emax) attained wíth 2C-B is less than that produced ...
-
(Blackwell Publishing Ltd, 1996)Microcin E492 is a polypeptide antibiotic that is produced and excreted by Klebsiella pneumoniae. Different growth conditions of the producer strain affect microcin activity. The production of a microcin antagonist is ...
-
(Resilience Alliance Acadia Univ, Biology Dept,, 2020)We used the adaptive cycle as a heuristic to conceptualize the changes in ecosystem services between its phases (growth, conservation, collapse, and reorganization) for Chiloé Island (southern Chile), analyzed as a ...
-
(JOHN WILEY & SONS INC, 2009-03-28)Some archaea of the Euryarchaeota present a unique version of the Embden–Meyerhof pathway where glucose and fructose- 6-phosphate are phoshporylated using ADP instead of ATP as the phosphoryl donor. These are the only ...
-
(Elsevier B.V., 2017)© 2017 Elsevier B.V. Current winemaking trends include low-temperature fermentations and using non-Saccharomyces yeasts as the most promising tools to produce lower alcohol and increased aromatic complexity wines. Here we ...
