Acclimatization in the Andes

Effect of Liquid Media and In Vitro Pre-acclimatization Stage on Shoot Elongation and Acclimatization of Date Palm (Phoenix dactylifera L.) cv. Najda

The effect of stationary liquid media to improve shoots elongation in date palm cv. Najda and an in vitro pre-acclimatization stage to increase the survival ercentage of plantlets in the greenhouse was investigated. Two basal liquid media were tested: full strength and half strength Murashige and Skoog medium (MS). Media were devoid of plant growth regulators (PGRs), containing 0.5 mg/L 6-benzy...

Human Adaptations in the Andes: a Look at Nutrition and Brain Function with Respect to Coca and High Altitude Physiological Adaptations

Morphophysiologicals Problems in Acclimatization of Micropropagated Plants in -­Ex Vitro Conditions- A Reviews

Plant tissue culture refers to growing and multiplication of cells, tissues and organs of plants on defined solid or liquid media under aseptic and controlled environment. Micropropagation allows rapid production of high quality, disease-free and uniform planting material. The micropropagation of high quality planting materials of ornamentals, and forest and fruit trees has created new opportun...

A multi-institutional and interdisciplinary approach to the assessment of vulnerability and adaptation to climate change in the Peruvian Central Andes: problems and prospects

A local integrated assessment of the vulnerability and adaptation to climate change in the Mantaro River Basin, located in Peruvian Central Andes, was developed between years 2003 to 2005. In this paper we present some lessons learned during the development of this study, emphasizing the multi-institutional and interdisciplinary efforts, briefly showing the methodological aspects, and pointing ...

Stepwise colonization of the Andes by ruddy ducks and the evolution of novel β-globin variants.

Andean uplift played a key role in Neotropical bird diversification, yet past dispersal and genetic adaptation to high-altitude environments remain little understood. Here we use multilocus population genetics to study population history and historical demographic processes in the ruddy duck (Oxyura jamaicensis), a stiff-tailed diving duck comprising three subspecies distributed from Canada to ...

Effect of cold acclimation on the photosynthetic performance of two ecotypes of Colobanthus quitensis (Kunth) Bartl.

The effects of cold acclimation of two ecotypes (Antarctic and Andes) of Colobanthus quitensis (Kunth) Bartl. Caryophyllaceae on their photosynthetic characteristics and performance under high light (HL) were compared. Non-acclimated plants of the Antarctic ecotype exhibited a higher (34%) maximal rate of photosynthesis than the Andes ecotype. In cold-acclimated plants the light compensation po...
