First published in English in 1970, the first chapter of the book is concerned with conditioned reactions. Jean Francois le Ny discusses ways in which conditioned reactions are acquired and the laws governing their function. The second contributor, Gerard de Montpellier, looks at different types of learning. The varying processes involved in both animal and human learning are considered, together with some general factors and mechanisms of learning. The third section of the book by Genevieve Oleron deals with the phenomenon of transfer. Among the topics included are the determination of transfer effects, transfer in perceptual-motor activities and explanations of transfer. In the final chapter, Cesar Flores examines memory, forgetting and reminiscence. The discussion covers methodology, the influence of material, the role of practice, the part played by attitudes, motivation and emotive reactions in the memory process, as well as the importance of organisation of memory tasks on the part of the subject.

Wild Plants for a Sustainable Future is an output from The Useful Plants Project, managed by Kew's Seed Conservation Department through the Millennium Seed Bank Partnership in Botswana, Kenya, Mali, Mexico and South Africa. Many inhabitants of these countries depend directly on natural vegetation for everyday needs such as food, medicine, fuel and building materials, and plants are faced with a range of threats that include climate change, over-exploitation, shortage of water, habitat loss and invasion of exotic species. The Useful Plants Project helps communities become better equipped to face such challenges by improving their livelihoods and using the surrounding resources in a more sustainable way. The book includes five chapters, compiled by experts from Botswana, Kenya, Mali, South Africa and Mexico. 110 species profiles are included, selected as being among the most important useful plants for the rural communities. Mostly thes are trees and shrubs, along with cacti, subshrubs, and perennial and annual herbs. Each species profile includes a description, information on taxonomy and nomenclature, fruits and seeds, distribution, habitat, uses, known hazards and safety, conservation status, seed conservation, propagation and trade. Illustrated throughout with images of the plants in the wild, associated habitats, seed morphology, and use in cultivation. Glossary of botanical and technical terms is included at the end of the book.
La produccion de ovinos es una actividad de gran trascendencia en pequenos productores pecuarios ya que son de facil manejo, su ciclo productivo es corto y existe una gran demanda. Sin embargo la incidencia de enfermedades en esta especie es alta, en el presente se consideran dos aspectos que afectan la presencia de padecimientos en ovinos; peso al nacimiento y se compara la ocurrencia de enfermedades animales de raza Suffolk y Dorset. La mayor cantidad de perdida de animales ocurren durante el peri-parto y la lactancia, el peso al nacimiento se relaciona con la sobrevivencia de la crias por lo que en el presente se investigan los factores que afectan el peso al nacimiento y como este factor se relaciona con la incidencia de enfermedades y supervivencia de corderos. Entre las diferencias que existen entre las razas de ovinos se encuentra la susceptibilidad, resistencia y recuperacion a las enfermedades, por lo que se analiza la incidencia de afecciones y la recuperacion de animales de la raza Suffolk y Dorset en condiciones semi-extensivas."
