This study was designed to test a vitrification method in Atlantic salmon spermatozoa and determine the capacity of seminal plasma (SP) to protect these cells from cryoinjuries. The vitrification medium consisted of a standard buffer for fish spermatozoa (Cortland medium) + 10% DMSO + 2% BSA + 0....

Atlantic salmon (Salmo salar) were fed 6 experimental dietscontaining three levels of arachidonic acid (ARA) (0.18 g kg(-1), 0.28 g kg(-1) and 0.63 g kg(-1) for low, medium and high levels, respectively) and two levels of vitamin E (150 and 730mgkg(-1) for low and high levels, respectively). At t...

The mathematical modeling of the unsaturated flow problem requires the simultaneous resolution of two problems: the Richards equation and the estimation of the hydraulic parameters involved in hydraulic conductivity and in the retention curve. Various techniques have been applied to both problems...
Decomposition of leaf litter is a fundamental process for the functioning of forested wetlands. The rapid increment of forest plantations has involved a greater contribution of leaf litter of exotic origin to these ecosystems. The decomposition rate between leaf litter of native and exotic origin...

Distributional patterns in Chile of species of the freshwater amphipod genus Hyalella were analysed. The results show that H. fossamanchini and H. kochi can be found in Andean mountain inland waters between 18-27 degrees S, H. costera in coastal inland waters between 24-40 degrees S, H. chiloensi...

The objectives of the study were to determine the effects of nutritional restriction on ovarian function in llamas. Mature female llamas were assigned randomly to a Control group, fed 100% of maintenance energy requirements (MER) (n = 8), or a Restricted group (n = 8) fed from 70% to 40% of MER u...

Reading levels in primary school students are still deficient in Chile and the Araucania region. Similarly, there is evidence that teachers' literacy practices are homogenous and their reading habits have an impact on the promotion of student reading. Therefore, the objective of the present inves...

The specific growth rate, G, is widely used in articles dealing with the growth of aquatic organisms under experimental conditions. When individuals are untagged, the arithmetic mean of G for a group of animals must be calculated from weight geometric means, not from arithmetic means. The type of...
