Epistemic restrictions in population biology
(1994)
Biologists have believed that the application of statistical or mathematical models to population biology has always been a correct and helpful tool to acquire knowledge. The present article demonstrates that the standard ...
Cell kinetics, stomatal differentiation, and diurnal rhythm in Allium cepa
(1973)
Cell kinetics parameters were obtained for the three mitotic divisions leading to formation of stomata in the epidermis of the cotyledon of Allium cepa seedlings. Analysis of mitotic frequencies throughout the course of ...
Frequency of chimerism in populations of the kelp Lessonia spicata in central Chile
(Public Library of Science, 2017)
Chimerism occurs when two genetically distinct conspecific individuals fuse together generating
a single entity. Coalescence and chimerism in red seaweeds has been positively
related to an increase in body size, and the ...
Effectiveness of corridors relative to enlargement of habitat patches
(2007)
The establishment of biological corridors between two otherwise isolated habitat patches is a common yet contentious strategy for conserving populations in fragmented landscapes. We compared the effectiveness of corridors ...
Estimation of the Effect of the Predator Scytodes globula (Araneae: Scytodidae) on Loxosceles laeta (Araneae: Sicariidae) Populations
(Oxford Univ Press, 2016)
It has been reported that Scytodes spiders are predators of spiders of the genus Loxosceles, but the question of the effect of Scytodes globula Nicolet on Loxosceles laeta (Nicolet) populations is still unanswered. The ...
Skeletal muscle excitation-metabolism coupling
(Academic Press Inc., 2019)
Mitochondria represent the main source of ATP in skeletal muscle and mitochondria activity increases after muscle fiber depolarization. The regulation of mitochondrial function during contraction in skeletal muscle, however, ...
Management of the Vicuña Vicugna vicugna in Chile: Use of a matrix model to assess harvest rates
(1989)
Some aspects of the population dynamics of the vicuña Vicugna vicugna were studied using census and field data recorded at the Reserva Nacional Las Vicuñas, I Region, northernmost Chile. Census data and mean values of ...
Genetic variation in Fitzroya cupressoides (alerce), a threatened South American conifer
(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, ...
Biochemical, immunological, and biological characterization of trypanosoma cruzi populations of the andean North of Chile
(1995)
Twenty-one Trypanosoma cruzi stocks isolated from Triatoma infestans and humans of the Chilean Andean highlands were studied at the genotypic level by schizodeme and molecular karyotype analyses, which allowed a clear ...
Lactase Non-Persistence and General Patterns of Dairy Intake in Indigenous and Mestizo Chilean Populations
(Wiley & Sons, 2016-03)
Objectives Lactase persistence (LP) is a genetic trait that has been studied among different countries and ethnic groups. In Latin America, the frequencies of this trait have been shown to vary according to the degree of ...
