Introducción a los SIG para futuras aplicaciones ambientales

Los embriones pueden parecernos seres indefensos, pero pocas personas saben que son unos inconformistas natos: cualquier modificación genética que afecte su desarrollo se traducirá en cambios anatómicos o funcionales en los adultos que, por leves que parezcan, son la piedra angular de la evolución y de la selección natural. Cambiar para sobrevivir, sobrevivir para cambiar. Si los embriones no estuvieran abocados al cambio, la evolución de los metazoos, es decir, de todos los animales, no habría sido posible. La evolución y el desarrollo embrionario forman una aleación biológica...

Behind the appearance of an innovative vaccine there is a history of determination and struggle, of breaking established models, and of overcoming the mistrust that generates a new theory. In this book we are going to learn about those stories, the stories of great scientists who fought to prove new theories and are now behind vaccines that save or will save millions of lives. We will experience with them the moment when they discovered that they had defeated a virus. We will travel inside the infectious agents to learn about their ability to gain ground in humans, the biological tools they...

Soil is a pivotal component of the environment and the maintenance of soil quality is critical for ensuring the sustainability of the environment and the biosphere. The use of fertilizers has increased at a faster rate than global food production. Modern agriculture is dependent on phosphorus derived from phosphate rock, which is a non-renewable resource. It is needed to improve P acquisition efficiency for both low input and intensive agroecosystems. However, few studies have focused on cereal-legume interactions with regard to soil P. The objective of this work was to study the effects of...
