“…() work in their simulations with up to ten trade links in networks of 100 nodes and with up to 20 connections in networks with 500 nodes. Similar, Nelson and Bone () in a horticultural trade network model use between four and eight average trade links. The expert judgement is illustrated by the example of Anthurium growers, where one large company is supplying about 60% of the market with plugs and small plants.…”

The Panel on Plant Health performed a pest risk assessment on Radopholus similis, the burrowing nematode for the EU. The quantitative assessment focused on entry, establishment, spread and impact on tropical and subtropical ornamental host plants, the main pathways for entry of R. similis into the EU. Infested consignments are expected to enter the risk assessment area on ornamentals under all scenarios. For citrus, which is a closed pathway for entry, outdoor establishment was assessed. Establishment may only take place after successful transfer from ornamental plants to citrus production systems. This event is called 'shift' in this assessment, to indicate that this is an unusual transfer. It has been estimated that establishment of this nematode in the open field in the EU citrus production areas under current temperatures is possible in most parts of the citrus production area in the EU. Temperature conditions will prevent the nematode from establishing only in the northernmost citrus areas and at higher altitudes in the south. Host plants for planting originating from infested places of production (greenhouses) within the risk assessment area are considered the main pathway for spread within the risk assessment area. Under current climatic conditions, the population of R. similis is not expected to reach damaging population levels in the open field. In case of increased temperatures due to global warming, the nematode population may reach damaging levels in very few places outdoors. Currently, main impact is considered for ornamental greenhouse production in the risk assessment area. Impact will be either caused by direct plant growth reductions or loss due to phytosanitary measures applied on regulated plants. Despite the fact that R. similis is globally considered as one of the most destructive plant parasitic nematodes, the impact in the risk assessment area is considered low.

“…Learning from what is taking place in public health would be beneficial too. Some additional focus on network theory (Nelson & Bone 2015), media monitoring (Alomar et al 2015), autonomous surveillance (Jurdak et al 2015), and the risks posed by internet trade (Humair et al 2015) would have been useful. Citizen science , as well as stakeholder involvement (Reed & Curzon 2015) and perceptions (Porth et al 2015), in invasion biology could also have benefited from some more attention.…”

“…Seed systems are amenable to network analysis because they are inherently networks with a suite of actors (network nodes) that move both genetic material and information through space and time (dynamic or static network links) (Pautasso 2015). Until recent years, plant disease epidemiologists have given relatively little attention to the study of seed system (and plant trade) networks, although the movement of planting material plays a fundamental role in the spread of plant disease and the persistence of epidemics (Buddenhagen et al 2017;Garrett et al 2017;McQuaid et al 2017;Nelson and Bone 2015;Pautasso 2015;Pautasso and Jeger 2008). Increasing availability of computational tools, coupled with advances in network analysis in the medical and social sciences, makes the implementation of network analysis for plant disease epidemiology more obtainable.…”

“…Our study draws on concepts developed for studying epidemic spread in hypothetical and empirical large-and small-scale plant trade networks (Buddenhagen et al 2017;Moslonka-Lefebvre et al 2011;Nelson and Bone 2015;Pautasso 2015;Pautasso and Jeger 2008;Pautasso et al 2010). We consider theory about the influence of node in-and out-degree on variety dissemination (and pathogen transmission) in small-scale, real-world seed networks (Pautasso 2015).…”
