Shrub facilitation increases plant diversity along an arid scrubland-temperate rainforest boundary in South America

Theoretical models predict nurse plant facilitation enhances species richness by ameliorating stressful environmental conditions and expanding distributional ranges of stress-intolerant species into harsh environments. We studied the role of nurse facilitation on the recruitment of perennial plants along an arid scrubland–temperate rain forest boundary to test the following predictions: (1) nurse shrub canopy increases seedling abundance and species richness along the rain forest–scrubland boundary; (2) scrubland species are less dependent on facilitative interactions than temperate rain forest species, especially at the moister, upper end of the gradient

The future of coffee and cocoa agroforestry in a warmer Mesoamerica

Climate change threatens cofee production and the livelihoods of thousands of families in Mesoamerica that depend on it. Replacing cofee with cocoa and integrating trees in combined agroforestry systems to ameliorate abiotic stress are among the proposed alternatives to overcome this challenge. These two alternatives do not consider the vulnerability of cocoa and tree species commonly used in agroforestry plantations to future climate conditions. We assessed the suitability of these alternatives by identifying the potential changes in the distribution of cofee, cocoa and the 100 most common agroforestry trees found in Mesoamerica. Here we show that cocoa could potentially become an alternative in most of cofee vulnerable areas. Agroforestry with currently preferred tree species is highly vulnerable to future climate change. Transforming agroforestry systems by changing tree species composition may be the best approach to adapt most of the cofee and cocoa production areas. Our results stress the urgency for land use planning considering climate change efects and to assess new combinations of agroforestry species in cofee and cocoa plantations in Mesoamerica

Assessing Factors that Influence Food Choices by Young Children

The prevalence of childhood obesity has tripled in the last 30 years (National Center for Health Statistics, 2011). This is particularly problematic given that obesity is associated with increased health risks. In addition to the increased health risks associated with obesity, several researchers contend that food preferences learned early in life are likely to influence long-term patterns of dietary intake (e.g., Haire-Joshu, Kreutter, Hold, & Steger-May, 2004; Skinner, Carruth, Bounds, & Ziegler, 2002). Therefore, a preventive approach to obesity that focuses on factors that influence food choices by young children is warranted. The current series of experiments were conducted to (a) empirically identify young children's preference for healthier and less-healthy foods within and across five food groups, (b) assess the relative influence of quality, magnitude, and immediacy of food on choices made by young children, and (c) determine whether results of the assessment are differentially affected by dense and lean schedules of reinforcement

Training manual on spatial analysis of plant diversity and distribution

This training manual is intended for scientists and students who work with biodiversity data and are interested in developing skills to effectively carry out spatial analysis based on (free) GIS applications with a focus on diversity and ecological analyses. These analyses offer a better understanding of spatial patterns of plant diversity and distribution, helping to improve conservation efforts. The training manual focuses on plants of interest for improving livelihoods (e.g. crops, trees and crop wild relatives) and/or those which are endangered. Spatial analyses of interspecific and intraspecific diversity are explained using different types of data: • species presence • morphological characterization data • molecular data Although this training focuses on plant diversity, many of the types of analyses described can also be applied for other organisms such as animals and fungi. The manual is based on specific exercises, based on real project data. In order to use the manual, you will also need to download (please click on reference material to download exercises) the relevant exercise data (listed below). Exercise data: 2.1 Importing observation data 5.2 Diversity - Phenotypic data 2.2 Importing climate data 5.3 Diversity - Molecular marker data 3.1 Basic elements 5.4 Conservation strategies 3.2 Export to Google Earth 6.1 Realized niche 4.1 Quality control – Administrative units 6.2_potential_distribution.zip 4.2 Quality control – Atypical points 6.3 Climate change 5.1 Species diversity 6.4 Gap analysis The manual can be used for self-learning as well as for training events like seminars or short courses on the fundamentals of spatial analysis

Towards a values framework for integrated health services:An international Delphi study

Background In order to organize person-centered health services for a growing number of people with multiple complex health and social care needs, a shift from fragmented to integrated health services delivery has to take place. For the organization of governance in integrated health services, it is important to better understand the underlying factors that drive collaboration, decision-making and behavior between individuals and organizations. Therefore, this article focuses on these underlying normative aspects of integrated health services. This study investigates the values that underpin integrated health services delivery as a concept, by examining the extent to which an initial literature based set of underlying values underpins integrated care and the relevance of these values on the different levels of integration. Methods An international Delphi study with 33 experts from 13 different countries was carried out to examine the initial set of underlying values of integrated health services. In addition, the relevance of the values was assessed on the different levels of integration: personal level, professional level, management level and system level. Results The study resulted in a refined set of 18 values of integrated health services developed in three Delphi study rounds. In addition, the results provided insight into the relevance of these values on the personal level (e.g. ‘trustful’), professional level (e.g. ‘collaborative’), management level (e.g. ‘efficient’) and system level (e.g. ‘comprehensive’) of integration. Some of the values score consistent across the different levels of integration while other values score inconsistent across these levels. Conclusions The Delphi study resulted in an international normative basis for integrated health services delivery as a concept. The values can be used as ingredients for a values framework and provide a better understanding of the normative aspects of integrated health services delivery. Future research could focus on associated behaviors in practice, the relationship between normative integration and governance, and differences between the value priorities of stakeholder groups
