Transformando la Ganadería: Evaluación de las Explotaciones de Vacunos

El estudio se realizó en 18 distritos de la provincia de Huancavelica, encuestando a 426 productores de bovino durante 2020. Los productores, con un nivel educativo primario o sin educación en su mayoría, se dedican principalmente a la agricultura y la ganadería, y no suelen recibir sueldo por su trabajo. La raza principal de ganado es la Brown Swiss (37.6%), y los productores mantienen un promedio de 6.5 cabezas de vacuno, con un sistema de producción semi extensivo. El objetivo principal de la crianza de bovinos es la producción de leche (46.9%) y doble propósito (44.1%), aunque la mayoría de los productores no puede determinar el peso vivo del bovino que vende. Aunque se practica el pastoreo y la suplementación con sal común, no se conservan pastos para la temporada seca, y la mayoría de los productores tiene dificultades para detectar el celo y determinar la edad al primer servicio. Predomina la monta natural, sin mejoramiento genético, y no se realiza un manejo adecuado de enfermedades como la mastitis y la fasciola. Los productores carecen de equipos y maquinarias, no reciben asistencia técnica adecuada y no siguen un calendario sanitario. Se concluye que la administración y la asistencia técnica en áreas como la reproducción, la sanidad, el mejoramiento genético y la alimentación son deficientes.

Ecology for All!

Ecology For All! Is an ecology text designed in modules so that instructors can choose the pieces that make sense to assign in their context. This book has been in development for several years and is a collaborative effort of authors at Gettysburg College, Franklin & Marshall College, and University of Pittsburgh. The textbook covers a wide range of topics including Introduction to Ecology, Evolution, Adaptations to the Physical Environment, various ecological communities, Population Ecology, Behavioral Ecology, Species Interactions, Ecological Succession, Biogeochemical Cycles, Landscape Ecology, Biodiversity, Conservation Biology, and Human Impact on Global Climate among others. The authors have presented on it at the Ecological Society of America meeting and the book continues to evolve.

Tree Steward Manual

Tree Steward Manual is designed for Virginia Cooperative Extension Master Gardeners who are training to be certified advanced Master Gardener tree stewards. Written by a dedicated team of volunteers who themselves completed advanced Master Gardener tree steward training, the manual covers a wide range of topics, specific to each region of Virginia, including identifying trees, selecting and planting appropriate trees for local landscapes, caring for trees, and troubleshooting tree problems. In Virginia, advanced Master Gardener tree steward training is offered by the local Extension Master Gardener (EMG) program. Once the training is completed, volunteers become certified advanced EMG tree stewards and commit to a specific number of volunteer hours working on local tree steward projects. EMG tree stewards work on projects based on the needs of their local community as determined mutually between the local agent/coordinator and active tree stewards. While Tree Steward Manual was developed with EMG training in mind, it is also appropriate for general readers who want to deepen their knowledge of trees and tree care. ​​ We would appreciate hearing from you.

Plant Molecular Genetics and Bioengineering

This edited book presents an overview of the fundamental principles and applied methodologies used in the genetic improvement of crop plants. It covers the structure and function of genes controlling traits of agronomic importance, the regulation of gene expression and genetic pathways, and the role of mutations as a primary source of genetic variation underlying trait improvement. Additional topics include an introduction to molecular markers, recombinant DNA technology, plant transformation, and gene editing technologies. Learning activities are included to facilitate self-study.

Mind, Body, World: Foundations of Cognitive Science

Cognitive science arose in the 1950s when it became apparent that a number of disciplines, including psychology, computer science, linguistics, and philosophy, were fragmenting. Perhaps owing to the field's immediate origins in cybernetics, as well as to the foundational assumption that cognition is information processing, cognitive science initially seemed more unified than psychology. However, as a result of differing interpretations of the foundational assumption and dramatically divergent views of the meaning of the term information processing, three separate schools emerged: classical cognitive science, connectionist cognitive science, and embodied cognitive science. Examples, cases, and research findings taken from the wide range of phenomena studied by cognitive scientists effectively explain and explore the relationship among the three perspectives. Intended to introduce both graduate and senior undergraduate students to the foundations of cognitive science, Mind, Body, World addresses a number of questions currently being asked by those practicing in the field: What are the core assumptions of the three different schools? What are the relationships between these different sets of core assumptions? Is there only one cognitive science, or are there many different cognitive sciences? Giving the schools equal treatment and displaying a broad and deep understanding of the field, Dawson highlights the fundamental tensions and lines of fragmentation that exist among the schools and provides a refreshing and unifying framework for students of cognitive science.
