(WFL PUBL, 2008-10)In this paper we evaluated the genetic diversity among apricot cultivars of different origins using SSR markers. Thirty-one apricot cultivars were evaluated, including one Japanese plum and one apricot x plum hybrid as ...
-
(1990)Controlled hand self- and cross-pollination and emasculations were performed on Ourisia poeppigii Benth. (Scrophulariaceae) from the Chilean Patagonia. Ourisia poeppigii is highly self-compatible and strongly autogamous. ...
-
(Public Library Science, 2018-06)One of the most relevant characteristics of the extant Southern Ocean fauna is its resiliency to survive glacial processes of the Quaternary. These climatic events produced catastrophic habitat reductions and forced some ...
-
(2011)The impact of recent habitat fragmentation on population genetic diversity and structure has often been studied, mainly related to anthropogenic causes; however its long-term effect has been much less evaluated. In this ...
-
(1998)Stable red astaxanthin-producing transformants were obtained after genetic transformation of two Phaffia rhodozyma mutants. A yellow mutant, accumulating β-carotene, and an albino mutant, accumulating phytoene, from P. ...
-
(1996)A wild Chilean population of coho salmon (Oncorhynchus kisutch (Walbaum, 1792)) was started using eggs imported from Oregon, U.S.A. A hatchery population was founded using eggs collected from this wild population, and a ...
-
(Blackwell, 1999)Fitzroya cupressoides (alerce, Cupressaceae) is a large and exceptionally long-lived conifer, endemic to a restricted area of southern Chile and neighbouring areas of Argentina. As a result of its high economic value, ...
-
(Springer, 2014)Background: The isolated watersheds of the southwestern Andean Altiplano constitute a natural laboratory to study the evolutionary divergence of freshwater biota. Field observations showed that Biomphalaria snails ...
-
(1997)In this work we establish the chromosomal composition of a wild-type, one astaxanthin and two β-carotene overproducer strains of the red yeast Phaffin rhodozyma. The method used has been pulsed field gel electrophoresis, ...
-
(National Academy of Sciences, 2020)Penguins are the only extant family of flightless diving birds. They currently comprise at least 18 species, distributed from polar to tropical environments in the Southern Hemisphere. The history of their diversification ...
-
(Natl Acad Sciences, 2018)Patagonia was the last region of the Americas reached by humans who entered the continent from Siberia similar to 15,000-20,000 y ago. Despite recent genomic approaches to reconstruct the continental evolutionary history, ...
-
(Sociedad de Biología de Chile, 2008-05-05)The cloning and nucleotide sequence of the genes (idi, crtE, crtYB, crtI and crtS) controlling the astaxanthin biosynthesis pathway of the wild-type ATCC 24230 strain of Xanthophyllomyces dendrorhous in their genomic and ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-04)The use of acidophilic, chemolithotrophic microorganisms capable of oxidizing iron and sulfur in industrial processes to recover metals from minerals containing copper, gold and uranium is a well established biotechnology ...
-
(Springer, 2019)This paper is an introduction to the fascinating world of Soergel bimodules and it should be accessible to a broad audience. We aim to help the reader feel comfortable with Soergel bimodules and to explain some of the ...
-
(Emerald Group Publishing Ltd, 2018)Purpose This study aims to explore the complex relationship between post-earthquake reconstruction processes and gentrification in neighbourhoods of intermediate cities, calling on the critical role of recovery strategies ...
-
(2012)Increasing research has attempted to clarify the links between animal personality and physiology. However, the mechanisms driving this association remain largely unknown, and knowledge of how ecological factors may affect ...

-
(OXFORD UNIV PRESS INC, 2010-08-06)Animal personalities are interindividual behavioral differences that are consistent across time or contexts. Increasing research is revealing the adaptive significance of personalities, although the mechanisms driving ...
-
(BLACKWELL, 2008-06)1. It has been proposed that habitats with low productivity, and hence low resource availability, may favour individuals with lower rates of resource use and energy expenditure. In birds, some studies have shown that basal ...
-
(Springer, 2020)The geographical distribution and ecological niche of the two circulating species of the Sporothrix genus in Venezuela was established. For this, 68 isolates of Sporothrix spp. from patients of different regions of the ...
