Data from: Are traded forest tree seeds a potential source of non-native pests?
The international seed trade is considered relatively safe from a phytosanitary point of view and is therefore less regulated than trade in other plants for planting. However, the pests carried by traded seeds are not well known. We assessed insects and fungi in 58 traded seed lots of eleven gymnosperm and angiosperm tree species from North America, Europe and Asia. Insects were detected by x-raying and molecular methods. The fungal community was characterised using high-throughput sequencing (HTS) and by growing fungi on non-selective agar. About 30% of the seed lots contained insect larvae. Gymnosperms contained mostly hymenopteran (Megastigmus spp.) and dipteran (Cecidomyiidae) larvae, while angiosperms contained lepidopteran (Cydia latiferreana) and coleopteran (Curculio spp.) larvae. HTS indicated the presence of fungi in all seed lots and fungi grew on non-selective agar from 96% of the seed lots. Fungal abundance and diversity were much higher than insect diversity and abundance, especially in angiosperm seeds. Almost 50% of all fungal Exact Sequence Variants (ESVs) found in angiosperms were potential pathogens, in comparison with around 30% of potentially pathogenic ESVs found in gymnosperms. The results of this study indicate that seeds may pose a greater risk of pest introduction than previously believed or accounted for. A rapid risk assessment suggests that only a small number of species identified in this study is of phytosanitary concern. However, more research is needed to enable better risk assessment, especially to increase knowledge about the potential for transmission of fungi to seedlings and the host range and impact of identified species.
Water use partitioning of native and non-native tree species in riparian ecosystems under contrasting climatic conditions
<p>We aimed at evaluating water-source partitioning between native and non-native tree species coexisting in central Spain floodplains; determining the dependency on drought stress of such water-sources-use; and assessing if the reliance on deeper water sources relates with physiological and growth performance. We assessed water-uptake depth, leaf functional traits related to physiological performance and growth of native (<em>Populus alba</em>) and non-native trees <em>(Ailanthus altissima, Robinia pseudoacacia</em>) coexisting in riparian forests under different drought conditions (drier, intermediate and wetter). We analyzed δ<sup>2</sup>H and δ<sup>18</sup>O isotopes in xylem water and in soil water from top, mid and deep soil depths and determined the contribution of each water source to plant xylem water. Leaf traits related with resource use and secondary growth were assessed for each species.</p>
