Using social media to measure the contribution of Red List species to the nature-based tourism potential of African protected areas

Cultural ecosystem services are defined by people’s perception of the environment, which make them hard to quantify systematically. Methods to describe cultural benefits from ecosystems typically include resource-demanding survey techniques, which are not suitable to assess cultural ecosystem services for large areas. In this paper we explore a method to quantify cultural benefits through the enjoyment of natured-based tourism, by assessing the potential tourism attractiveness of species for each protected area in Africa using the IUCN’s Red List of Threatened Species. We use the number of pictures of wildlife posted on a photo sharing website as a proxy for charisma, popularity, and ease of observation, as these factors combined are assumed to determine how attractive species are for the global wildlife tourist. Based on photo counts of 2473 African animals and plants, species that seem most attractive to nature-based tourism are the Lion, African Elephant and Leopard. Combining the photo counts with species range data, African protected areas with the highest potential to attract wildlife tourists based on attractive species occurrence were Samburu National Reserve in Kenya, Mukogodo Forest Reserve located just north of Mount Kenya, and Addo Elephant National Park in South-Africa. The proposed method requires only three data sources which are freely accessible and available online, which could make the proposed index tractable for large scale quantitative ecosystem service assessments. The index directly links species presence to the tourism potential of protected areas, making the connection between nature and human benefits explicit, but excludes other important contributing factors for tourism, such as accessibility and safety. This social media based index provides a broad understanding of those species that are popular globally; in many cases these are not the species of highest conservation concern.JRC.H.5-Land Resources Managemen

Workshop Bescherm de planten!

Op verzoek van het NIBI, het Nederlands Instituut voor Biologie, verzorgde de landelijke scholierenwebsite www.plantenziektekunde.nl tweemaal een workshop tijdens de jaarlijkse NIBI-conferentie voor biologiedocenten. De bijeenkomst had deze keer als thema ‘Bescherm jezelf!

Fallen fragment sign

A 16-year-old boy presented at the emergency room after he fell on his left shoulder while playing American football. Plain radiographs showed a pathological fracture through a well- defined expansile radiolucent lesion within the proximal meta-diaphysis of the left humerus (Fig. A). The lesion caused cortical thinning and contained multiple linear cortical fragments within the central part of the lesion (arrows in Fig. A). Based on the age, location and the plain radiographic characteristics (“fallen fragment sign”), the diagnosis of a solitary bone cyst (SBC) was suggested

Cardiovascular co-medication among users of antiobesity drugs: a population-based study

Aim The purpose of this study was to investigate to what extent patients using prescription antiobesity drugs (orlistat, sibutramine and rimonabant) used cardiovascular and antidiabetic drugs. An additional aim was to investigate whether such co-medication differed according to gender, age and amount of antiobesity drugs used. Method Data were retrieved from the Norwegian Prescription Database (NorPD). All patients who had an antiobesity drug (ATC code A08A) dispensed from a Norwegian pharmacy between January 2004 and December 2007 were included in the study. Results During the 4-year study period 83,717 patients had antiobesity drugs dispensed. One in three patients using antiobesity drugs had at least on one occasion used a cardiovascular and/or an antidiabetic drug concomitantly. A significantly higher percentage of men used antihypertensives (40.4 vs. 27.2%, P < 0.0005), lipid modifying agents (24.4 vs. 11.9%, P < 0.0005) and drugs used in diabetes (12.7 vs. 6.4%, P < 0.0005) concomitantly with antiobesity drugs when compared to women. The percentage of patients who had concomitant drug use increased markedly with age. One in four patients had antiobesity drugs dispensed only once during the period 2004–2007. Conclusion Use of cardiovascular and antidiabetic drugs among patients using antiobesity drugs was extensive, especially among men and elderly patients. Overall, there was a high degree of polypharmacy among users of antiobesity drugs. Also, many patients dispensed antiobesity drugs in amounts that indicated use less than the recommended daily dose, and many dispensed antiobesity drugs only once. When prescribing antiobesity drugs to patients the potential benefits of antiobesity drugs should be considered in relation to the patients other chronic diseases and to the total complexity of the patients drug regimen

Winegrowers’ decision-making: A pan-European perspective on pesticide use and inter-row management

European viticultural landscapes not only support a significant share of rural livelihoods and cultural traditions, but also conserve biodiversity and sustain various ecosystem services. Winegrowers' practices of inter-row management (including whether to have vegetation in the inter-rows, type of vegetation, duration of vegetation cover, and soil tillage) and pesticide use (including herbicides in the inter-rows, fungicides, insecticides, and pheromone dispensers as an alternative) can affect these services. This study aims to understand winegrowers' decision-making driven by their personal characteristics, attitudes and beliefs towards viticultural practices, physical properties of vineyards, and farm management characteristics in five European winegrowing regions. These include Palatinate in Germany, Leithaberg in Austria, Tarnave in Romania, Bordeaux in France, and Montilla-Moriles in Spain. Based on a questionnaire survey, we constructed decision trees for each behaviour per case study as well as in a generic European model. We found factors that best explain how winegrowers manage their inter-rows and use pesticides. Results showed that not only do behaviours of winegrowers vary drastically across the case studies, but also the factors that explain most behaviours: farmers' attitudes and beliefs and farm management characteristics. This implies the importance of attitudes and beliefs – which are under-researched as compared to other factors – in understanding farmers’ behaviour. With the driving factors found to vary per case study, our results also imply the need for locally-adapted policies. Furthermore, our results suggest that the effects of climate change on European viticultural landscapes concern not only shifting production regions and changes in yields, but also changing pressure of pests and diseases. Any long-term behavioural change requires efforts from many stakeholders.This research was funded by the research project SECBIVIT which was funded through the 2017–2018 Belmont Forum and BiodivERsA joint call for research proposals, under the BiodivScen ERA-Net COFUND programme, with the funding organisations: Agencia Estatal de Investigación (Ministerio de ciencia e innovación/Spain), Austrian Science Fund (FWF) (grant number I 4025-B32), Federal Ministry of Education and Research (BMBF/Germany) through VDI/VDE Innovation + Technik GmbH, DLR Projektträger, French National Research Agency (ANR), Netherlands Organisation for Scientific Research (NWO), National Science Foundation (Grant #1850943) and Romanian Executive Agency for Higher Education, Research, Development and Innovation Funding (UEFISCDI).

Distribution, diversity and environmental adaptation of highland papaya (Vasconcellea spp.) in tropical and subtropical America

Vasconcellea species, often referred to as highland papayas, consist of a group of fruit species that are closely related to the common papaya (Carica papaya). The genus deserves special attention as a number of species show potential as raw material in the tropical fruit industry, fresh or in processed products, or as genetic resources in papaya breeding programs. Some species show a very restricted distribution and are included in the IUCN Red List. This study on Vasconcellea distribution and diversity compiled collection data from five Vasconcellea projects and retrieved data from 62 herbaria, resulting in a total of 1,553 georeferenced collection sites, in 16 countries, including all 21 currently known Vasconcellea species. Spatial analysis of species richness clearly shows that Ecuador, Colombia and Peru are areas of high Vasconcellea diversity. Combination of species occurrence data with climatic data delimitates the potential distribution of each species and allows the modeling of potential richness at continent level. Based on these modeled richness maps, Ecuador appears to be the country with the highest potential Vasconcellea diversity. Despite differences in sampling densities, its neighboring countries, Peru and Colombia, possess high modeled species richness as well. A combination of observed richness maps and modeled potential richness maps makes it possible to identify important collection gaps. A Principal Component Analysis (PCA) of climate data at the collection sites allows us to define climatic preferences and adaptability of the different Vasconcellea species and to compare them with those of the common papaya
