“…Areas with dense human population are consequently relevant sources of alien species owing to: (1) the release and escape of alien species kept as pets (Spear et al ., ), (2) the intensity of tourism, which is directly associated with the pathways of introduction (e.g. ornamental trade and tourism, Hulme, ) and (3) the intensity of anthropogenic disturbance, which can be considered as a proxy of risk of invasion (Hulme, ; Spear et al ., ; Dalmazzone & Giaccaria, ).…”

Understanding how the diversity of invasive species is geographically distributed and identifying the major drivers of that pattern is a relevant challenge as regards invasion biology. The aim of this paper was, therefore, to identify and characterize those areas colonized by a high number of alien species as a means to provide directional indications that can be used to minimize the potential negative effects that the alien species may have on host ecosystems. This is done by applying spatially explicit predictive modeling in order to explain the diversity of vertebrate alien species in Spain. The relative importance of the different factors was assessed using variation partitioning. Our results showed that the main factor as regards predicting the distribution of alien species was the anthropogenic variable, and that this was followed by abiotic variables. The other significant predictor of alien species was the number of native species, which had a positive relationship with the number of alien species. This accord with the 'the rich get richer' acceptance hypothesis, which predicts a higher number of alien species in areas with high native species diversity. In this study, we detected actual conflict areas (ACAs), which have high-medium values for the number of both native and alien species.

“…Multiple studies have emphasized the importance of economics and trade in shaping global patterns of exotic species richness based on analyses of regional or global databases – generally species checklists that do not contain measures of sampling effort (Dalmazzone & Giaccaria, ; Essl et al, ; Gren & Campos, ; Pyšek et al, ; Westphal et al, ). We found that the number of shared U.S. exotic plant species in each country globally was more closely related to climatic (dis)similarity than to patterns of trade.…”

“…Invasion ecology has long recognized that the observed richness of exotic or invasive species reflects the outcome of sampling processes, justifying the use of species richness estimators (Levine & D'Antonio, ). Nevertheless, global and regional analyses aiming to quantify the impacts of trade and other economic factors on species introductions and invasions have often been based on observed exotic or invasive richness derived from checklists such as the Global Invasive Species Database (GISD) and Delivering Alien Invasive Species Inventories for Europe (DAISIE); sampling bias is often recognized as a potential issue, but is generally not explicitly accounted for analytically (e.g., Dalmazzone & Giaccaria, ; Essl et al, ; Gren & Campos, ; Liu, Liang, Liu, Wang, & Dong, ; Pyšek et al, ; Seebens et al, ; Sharma, Esler, & Blignaut, ; Taylor & Irwin, ; Vila & Pujadas, ; Westphal et al, ). In contrast, ecological analyses focusing on biodiversity have shown that the number of records in a database is strongly correlated with observed species richness, and can be used as a measure of sampling effort (e.g., Lobo, ; Yang, Ma, & Kreft, ).…”

Aim The distributions of exotic species reflect patterns of human‐mediated dispersal, species climatic tolerances and a suite of other biotic and abiotic factors. The relative importance of each of these factors will shape how the spread of exotic species is affected by ongoing economic globalization and climate change. However, patterns of trade may be correlated with variation in scientific sampling effort globally, potentially confounding studies that do not account for sampling patterns. Location Global. Time period Museum records, generally from the 1800s up to 2015. Major taxa studied Plant species exotic to the United States. Methods We used data from the Global Biodiversity Information Facility (GBIF) to summarize the number of plant species with exotic occurrences in the United States that also occur in each other country world‐wide. We assessed the relative importance of trade and climatic similarity for explaining variation in the number of shared species while evaluating several methods to account for variation in sampling effort among countries. Results Accounting for variation in sampling effort reversed the relative importance of trade and climate for explaining numbers of shared species. Trade was strongly correlated with numbers of shared U.S. exotic plants between the United States and other countries before, but not after, accounting for sampling variation among countries. Conversely, accounting for sampling effort strengthened the relationship between climatic similarity and species sharing. Using the number of records as a measure of sampling effort provided a straightforward approach for the analysis of occurrence data, whereas species richness estimators and rarefaction were less effective at removing sampling bias. Main conclusions Our work provides support for broad‐scale climatic limitation on the distributions of exotic species, illustrates the need to account for variation in sampling effort in large biodiversity databases, and highlights the difficulty in inferring causal links between the economic drivers of invasion and global patterns of exotic species occurrence.

In China, with the deepening of the reform of industrial structures, the improvement of technological innovation has become a key issue. This is not only related to whether the strategic development of Chinese science and technology can be achieved, but also whether the Chinese economy and high-quality human capital can develop sustainably. Based on the theoretical boundary of sustainable development-free transfer of information-we see that sticky wages are the embodiment of information dissemination. Under the dual effects of profit-seeking behavior and information barriers, the relationship between the sticky wages of technological innovation talents (TIT), as the most profitable labor force, and technological innovation efficiency (TIE) has become more complex, and so far we still have a limited understanding of it. We explore this issue in an empirical study by using a two-stage chain Data Envelopment Analysis (DEA) of TIE followed by modifying the wages of TIT; finally, we build a collaborative evolution model with spatial effects on a large dataset (from 2007 to 2016). The results show that the overall Chinese TIE is relatively low, and in the central and western regions the TIE has been seriously reversed; there are also divergences in the TIE at different stages in the regions we focus on. As the output of technological innovation, except for initial results (such as patents), the more important value is whether it has an ability to transform the initial results into production, and the core of it is whether it can match the market environment and technology transfer system (for example, market mechanism, transformation incentive mechanism, and institutional mechanism). So, considering these aspects, the central and west of China are obviously insufficient, while the east has obvious advantages; this can also explain the results of spatial diffusion, namely, in the eastern region it is higher than in other areas, but the gap between them is gradually narrowing; lastly, from the perspective of synergy, the wage stickiness of TIT in the central region is larger than that of the eastern and western regions, and the evolutionary relationship in the former is "extruding" while in the latter it is "cooperative." Mainly due to the popularity of the eastern innovation network and the initial state of the west, the barriers of information transmission are relatively low, while the central part is undergoing economic transformation, so its extreme demand for TIT has pushed up the cost of information transmission.
