La Didáctica a través de experiencias de aula.
Este libro presenta la visión de miembros del Grupo de Innovación Docente Equidad e Inclusión Educativa (EIE-GID), de la Universidad de Murcia, sobre la enseñanza en las etapas de Educación Infantil y Educación Primaria. Se desarrolla aquí el posicionamiento que los autores han configurado sobre aspectos didácticos básicos, que necesariamente forman parte de la enseñanza en estas etapas: qué significa ser maestro, principios educativos y componentes curriculares. Entendemos que cualquier propuesta que se establezca cobra significado en los contextos en los que se desarrolla, pero basándose en principios y fundamentos claros; por ello, para cada uno de los tópicos mencionados se ...
Rediscovering Local Landraces: Shaping Horticulture for the Future
Local landraces are traditional crop varieties cultivated in specific locations. However, the intensification of modern horticulture has put these genotypes aside, since farmers tend to select hybrids or commercial cultivars due to higher yield, uniformity and marketability. The various landraces are very distinct in their quality features, therefore it is of high importance to highlight these differences and identify genotypes that could be further exploited by producing high added value products and by reinforcing local rural economies. The proposed Research Topic aims to reveal the importance of local landraces for sustainable horticulture, focusing on their special quality features as the result of adaptation to specific growing conditions after domestication.
Remittance Markets in Africa
Remittances sent by African migrants have become an important source of external finance for countries in the Sub-Saharan African region. In many African countries, these flows are larger than foreign direct investment and portfolio debt and equity flows. In some cases, they are similar in size to official aid from multilateral and bilateral donors. Remittance markets in Africa, however, remain less developed than other regions. The share of informal or unrecorded remittances is among the highest for Sub-Saharan African countries. Remittance costs tend to be significantly higher in Africa both for sending remittances from outside the region and for within-Africa (South-South) remittance corr...

Salinity Tolerance in Plants: Mechanisms and Regulation of Ion Transport
Life presumably arose in the primeval oceans with similar or even greater salinity than the present ocean, so the ancient cells were designed to withstand salinity. However, the immediate ancestors of land plants most likely lived in fresh, or slightly brackish, water. The fresh/brackish water origins might explain why many land plants, including some cereals, can withstand moderate salinity, but only 1 – 2 % of all the higher plant species were able to re-discover their saline origins again and survive at increased salinities close to that of seawater. From a practical side, salinity is among the major threats to agriculture, having been one of the reasons for the demise of the ancient Me...
Crop Resistance Mechanisms to Alleviate Climate Change-Related Stress
Anthropogenic activities have aggravated the effects of global climate change on ecosystems. Plants, because of their inability to escape from an adverse environment, suffer to a great extent from stresses, which can negatively impact their growth and development. Global warming is increasingly causing extreme climatic situations such as very high or low temperatures, drought and flooding events, hailstorms, wildfires, extreme precipitation events, and the reduction of fertile soil through desertification and salinization. In addition, warmer temperatures and higher humidity related with the climate change can also increase pest and disease pressure on plants by altering the geographic range, population size, and timing of pest and disease outbreaks. Taken together abiotic stress related with climate change as drought or extreme temperature can exacerbate the spread and severity of various diseases associated with biotic stress increasing the vulnerability of plants to pathogens (some examples include insects, fungi, bacteria or viruses).
