-
(2006)It is generally assumed that larvae of benthic species are thoroughly mixed in the plankton and distributed randomly at settlement. Yet, it has also been hypothesized that a combination of larval gregarious behaviour coupled ...
-
(1977)The genetic information of Φx 174 genome (genes and intermediate segments) is analyzed in terms of its independent (D1 index) and dependent information (D2 and D3 Markovian indexes), as well as of its ability to generate ...
-
(Oxford University Press, 2020)Accurate taxonomic identification of alien species is crucial to detect new incursions, prevent or reduce the arrival of new invaders and implement management options such as biological control. Globally, the taxonomy of ...
-
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2005-12)The concerted action of extracellular signals such as BMP, Wnt, FGF, RA and Notch activate a genetic program required to transform a naive ectodermal cell into a neural crest cell. In this review we will analyze the ...
-
(Frontiers Media SA, 2017)Rare species frequently occur in areas with microclimatic conditions that are atypical for their regions, but that were more common in the past, and that probably have operated as climatic refugia for a long time. Myrceugenia ...
-
(Universidad Católica de Valparaíso, 2017)The study of species in their native geographic ranges is key to understanding how human activity has influenced spatial fragmentation or species homogenization. The Argentinian silverside Odontesthes bonariensis, of ...
-
(2009)The Chilean jack mackerel Trachurus murphyi, is a pelagic fish from the Carangidae family that is distributed in the South Pacific Ocean. Because this species constitutes an important economic resource across the South ...
-
(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 ...
