Differences of the Fertility Potential between Buffaloes (Bubalus bubalis) and Cattle (Bos indicus): The Role of Antimullerian Hormone (AMH)

For years the study of the differences in reproduction between bovines have been restricted to describe the consequences not the causes, it is very easy to find differences in parameters such as embryo/oocyte morphology, metabolism, cleavage rate, but it is quite difficult to find papers trying to explain the reason of this differences and it is not possible to identify their influence in the reproductive parameters and answer to reproductive biotechnologies. The idea that the quantity of follicles and oocytes in ovaries impacts on fertility is a long-held tenet in reproductive biology (46), Follicle formation occurs during fetal life in ruminants and primates. The establishment of the pool of primordial follicles is critical to a female’s reproductive success, but very little is known about how this important developmental process is regulated. It has been reported is has been reported in buffaloes the effect of season in the gene expression of oocytes and follicles(47) .However, until now very few studies has been attempted to evaluate this fundamental hypothesis, it is possible to think that animals with low follicle count such buffaloes has lower fertility than cattle but this must be demonstrated. The aim of this review is to present evidence related to the differences in reproductive potential in two closely related bovines: buffaloes (Bubalus bubalis) and cattle (Bos taurus and Bos indicus), with special emphasis in the role of antimullerian hormone (AMH) and discuss their possible role in the application of reproductive biotechnologies

Cultivo de papa en el suroeste colombiano: tipos de agricultores y eficiencia técnica

Potato is a traditional and economically important crop for farmers in the high mountains of Nariño (Colombia). However, its productivity growth is weakening, injuring farmers’ livelihoods. We hypothesize that an in-depth study of farm typologies and their relationship with productive efficiency could prove helpful in delivering recommendations for sector improvement. With a representative sample of 1,018 farmers, this research used cluster methods to identify representative types of farming and then a stochastic frontier model to build a measure of potato production efficiency. Finally, it analyzed how technical efficiency behaves across the calculated types of farming. Results suggested that four kinds of farming describe potato production in Nariño: micro, small, medium, and large-scale. Most farmers are of the micro (71.8 %) and small scale (23.8 %), and their conditions are unfavorable in terms of access to technical assistance, credit, and improved production practices. Although these farmers report an average efficiency of 79 % and 85 %, respectively, there is still an opportunity for improvement. We close with a brief discussion that focuses on suggestions for future policy or research advances around these farmers.La papa es un cultivo de tradición y relevancia económica para los agricultores de montaña en Nariño (Colombia). Sin embargo, el crecimiento de su producción reporta un aparente estancamiento, lo cual podría poner en riesgo a los productores paperos. Un estudio a profundidad de las tipologías de producción y su conexión con la eficiencia productiva pueden ser clave para brindar recomendaciones con base en la evidencia. Partiendo de una muestra representativa de 1018 paperos, esta investigación usa métodos de clúster para identificar tipologías de hogares productores, para luego ajustar una frontera estocástica que permite crear una medida de eficiencia técnica. Por últimos, se analizó la forma en que la eficiencia técnica varía a través de las tipologías identificadas. Los resultados mostraron que cuatro tipos de producción describen a los paperos de Nariño: micro, pequeños, medianos y grandes productores. La mayoría de estos son de escala micro (71,8 %) y pequeña (23,8 %), y sus condiciones son desfavorables en lo que respecta a acceso a asistencia técnica, crédito y adopción de prácticas agronómicas mejoradas. Aunque estos productores presentan niveles medios de eficiencia de 79 % y 85 %, respectivamente, aún hay posibilidades de mejora. El documento cierra con una breve discusión que se enfoca en sugerir futuros trabajos de investigación o política alrededor de estos productores

Environmental risk assessment of PPP application in European soils and potential ecosystem service losses considering impacts on non-target organisms

The use of Plant Protection Products (PPPs) is leading to high exposure scenarios with potential risk to soil organisms, including non-target species. Assessment of the effects of PPPs on non-target organisms is one of the most important components of environmental risk assessment (ERA) since they play crucial functions in ecosystems, being main driving forces in different soil processes. As part of the framework, EFSA is proposing the use of the ecosystem services approach for setting specific protection goals. In fact, the services provided by soil organisms can be impacted by the misuse of PPPs in agroecosystems. The aim of this work was to assess PPPs potential risk upon ecosystem services along European soils, considering impacts on earthworms and collembola. Four well-known (2 insecticides-esfenvalerate and cyclaniliprole- and 2 fungicides - picoxystrobin and fenamidone-) worst case application (highest recommended application) were studied; exploring approaches for linked observed effects with impacts on ecosystem services, accounting for their mode of action (MoA), predicted exposure, time-course effects in Eisenia fetida and Folsomia sp. and landscape variability. The selected fungicides exerted more effects than insecticides on E. fetida, whereas few effects were reported for both pesticides regarding Folsomia sp. The most impacted ecosystem services after PPP application to crops appeared to be habitat provision, soil formation and retention, nutrient cycling, biodiversity, erosion regulation, soil remediation/waste treatment and pest and disease regulation. The main factors to be taken into account for a correct PPP use management in crops are discussed.This work has been partially funded by European Food Safety Authority (EFSA) through the grant NP/EFSA/AFSCO/2016/03.

Children and disasters: understanding impact and enabling agency

From a child rights perspective disaster impacts affect not only a child's basic right to survival and development, but cut across their right to participate and for decisions to be made in their best interests. Child-centred approaches recognise the role and rights of children as citizens and agents of change, seeking to engage them in DRR/CCA (Disaster Risk Reduction/Climate Change Adaptation) decision-making and accountability processes and supporting child-centred community-based programmes of action. The research produced two papers, one on Undertanding Impacts of disasters on child welfare, and the second to identify the factors which create an enabling environment for children to engage in climate change and disaster risk reduction. This report synthesises the research outputs to produce a comprehensive report looking into the need both for child sensitive programmes to tackle disasters and climate change, but also at the need for child participation in programming and polic
