a r t i c l e i n f o Although the oceans cover 70% of the surface of the planet few studies have considered the economic valuation of marine biodiversity, despite the importance of such information for marine management and conservation. This study uses a contingent valuation method to estimate the public's willingness to pay (WTP) to avoid loss in the(More)
Altering root morphology of rice (Oryza sativa L.) cultivars could improve yields in drought-prone upland ecosystems. Marker-assisted backcross breeding was used to introgress four QTLs for root traits into an upland rice cultivar. The QTLs had previously been identified under experimental conditions in a different genetic background. The introgressed lines(More)
International agreements and policies play an increasingly prominent role in strategies to combat biodiversity loss. However, conservation policies can only have a conservation impact if implemented. Identifying factors determining the influence of a policy on institutions could improve the process of policy development and communication. We examine how and(More)
Who Harvests and Why? Characteristics of Guatemalan Households Harvesting Xaté (Chamaedorea ernesti-augusti). Cultivation of harvested species is frequently proposed as a conservation strategy to reduce wild harvesting pressure and improve local livelihoods. The success of this approach is likely to be influenced by harvesters’ socioeconomic(More)
This study focused on the use of antibiotics on small, medium and commercial-sized dairy farms in the central region of Zambia and its relationship to antibiotic resistance in Escherichia coli. A stratified random sample of 104 farms was studied, representing approximately 20% of all dairy farms in the region. On each farm, faecal samples were collected(More)
Cultivation of wild-harvested plant species has been proposed as a way of reducing over-exploitation of wild populations but lack of technical knowledge is thought to be a barrier preventing people from cultivating a new species. Training programmes are therefore used to increase technical knowledge to encourage people to adopt cultivation. We assessed the(More)
INTRODUCTION Campylobacter jejuni is the leading bacterial food-borne pathogen within the European Union, and poultry meat is an important vehicle for its transmission to humans. However, there is limited knowledge about how this organism persists in broiler litter and faeces. The aim of this study was to assess the impact of a number of environmental(More)
BACKGROUND Campylobacter jejuni is the leading bacterial food-borne pathogen within the European Union (EU), and poultry meat is the primary route for transmission to humans. MATERIAL AND METHODS This study examined the impact of partial depopulation (thinning), season, and farm performance (economic, hygiene, and biosecurity) on Campylobacter prevalence(More)
