Abstract The globalization of trade and human movement has resulted in the accidental dispersal of thousands of alien species worldwide at an unprecedented scale. Some of these species are considered invasive because of their extensive spatial spread or negative impacts on native biodiversity. Explaining which alien species become invasive is a major challenge of invasion biology, and it is often assumed that invasiveness is linked to a greater ability to establish in novel climates. To test whether invasive species have expanded more into novel climates than non-invasive alien species, we quantified niche shifts of 82 ant species. Surprisingly, invasive species showed smaller niche shifts than non-invasive alien species. Independent of their invasiveness, the species with the smallest native niches and range sizes, experienced the greatest niche shifts. Overall, our results challenge the assumption that invasive species are particularly good pioneers of novel climates.

Reducing the damage caused by invasive species requires a community approach informed by rapidly mobilized data. Even if local stakeholders work together, invasive species do not respect borders, and national, continental and global policies are required. Yet, in general, data on invasive species are slow to be mobilized, often of insufficient quality for their intended application and distributed among many stakeholders and their organizations, including scientists, land managers, and citizen scientists. The Belgian situation is typical. We struggle with the fragmentation of data sources and restrictions to data mobility. Nevertheless, there is a common view that the issue of invasive alien species needs to be addressed. In 2017 we launched the Tracking Invasive Alien Species (TrIAS) project, which envisages a future where alien species data are rapidly mobilized, the spread of exotic species is regularly monitored, and potential impacts and risks are rapidly evaluated in support of policy decisions (Vanderhoeven et al. 2017). TrIAS is building a seamless, data-driven workflow, from raw data to policy support documentation. TrIAS brings together 21 different stakeholder organizations that covering all organisms in the terrestrial, freshwater and marine environments. These organizations also include those involved in citizen science, research and wildlife management. TrIAS is an Open Science project and all the software, data and documentation are being shared openly (Groom et al. 2018). This means that the workflow can be reused as a whole or in part, either after the project or in different countries. We hope to prove that rapid data workflows are not only an indispensable tool in the control of invasive species, but also for integrating and motivating the citizens and organizations involved.

ALAS aims to fill knowledge gaps on the impacts of marine alien species in the Aegean Sea, and support marine managers and policy makers in prioritizing mitigation actions. The project will focus on under-studied alien-native interactions, priority and vulnerable habitats (such as shallow forests of canopy algae and underwater caves), and apply a multitude of approaches. It will apply a standardized, quantitative method for mapping Cumulative IMpacts of invasive Alien species on marine ecosystems (CIMPAL), according to which cumulative impact scores are estimated on the basis of the distributions of invasive species and ecosystems, and both the reported magnitude of ecological impacts and the strength of such evidence. Towards that direction, ALAS will improve our knowledge base and compile the needed information to estimate CIMPAL by (1) conducting a series of field experiments and surveys to investigate the impacts of selected invasive alien species on marine habitats, (2) producing high-resolution habitat maps in the coastal zone, refining the results of previous research efforts through fieldwork, remote sensing and satellite imaging, (3) producing species distribution models for all invasive species, based on extensive underwater surveys for the collection of new data and integrating all existing information. ALAS will incorporate skills and analyses in novel ways and provide high-resolution results at a large scale; couple classic and novel tools and follow a trans-disciplinary approach, combining knowledge from the fields of invasion biology, conservation biology, biogeography, fisheries science, marine ecology, remote sensing, statistical modelling; conduct for the first time in the Aegean Sea a comprehensive, high-resolution analysis of cumulative impacts of invasive alien species; and report results in formats appropriate for decision-makers and society, thus transferring research-based knowledge to inform and influence policy decisions.

River pollution has been a major problem in Malaysia and significantly affects the environment. One of the contributing issues would be the spread of invasive alien fish species that has given negative impacts on the environment and ecological disaster, the human health, harming the native animals and plants, as well the economy. Based on the National Committee on Invasive Alien Species Report in 2018, that 46 invasive alien species from a total of 130 species in the established main invasive alien species lists in Malaysia.  The alien fishes have been known to make their presence in our dams, lakes and rivers but not much attention has been paid to their existence. Based on these facts, it is proven that the issue poses a significant risk hence an urgent attention is required in managing this pollution through proactive legal measures to enforce strictly the existing law so as to prevent the halt of the spread of invasive species. A legal doctrinal and non-doctrinal modes of research are used to examine and review on the existing laws and/or policy governing this issue. This research will help to provide reference and strategic planning via legal approach for better controlling the invasion in our Malaysian waters.

Aim: Large-scale datasets are becoming increasingly available for macroecological research from different disciplines. However, learning their specific extraction and analytical requirements can become prohibitively time-consuming for researchers. We argue that this issue can be tackled with the provision of methodological frameworks published in open-source software. We illustrate this solution with the invacost R package, an open-source software designed to query and analyse the global database on reported economic costs of invasive alien species, InvaCost. Innovations: First, the invacost package provides updates of this dynamic database directly in the analytical environment R. Second, it helps understand the nature of economic cost data for invasive species, their harmonisation process, and the inherent biases associated with such data. Third, it readily provides complementary methods to query and analyse the costs of invasive species at the global scale, all the while accounting for econometric statistical issues. Main conclusions: This tool will be useful for scientists working on invasive alien species, by (i) facilitating access and use to this multi-disciplinary data resource and (ii) providing a standard procedure which will facilitate reproducibility and comparability of studies, one of the major critics of this topic until now. We discuss how the development of this R package was designed as an enforcement of general recommendations for transparency, reproducibility and comparability of science in the era of big data in ecology.

Invasive alien species (IAS) are a leading driver of biodiversity loss worldwide, and have negative impacts on human societies. In most countries, available data on monetary costs of IAS are scarce, while being crucial for developing efficient management. In this study, we use available data collected from the first global assessment of economic costs of IAS (InvaCost) to quantify and describe the economic cost of invasions in Mexico. This description was made across a range of taxonomic, sectoral and temporal variables, and allowed us to identify knowledge gaps within these areas. Overall, costs of invasions in Mexico were estimated at US$ 5.33 billion (i.e., 109) ($MXN 100.84 billion) during the period from 1992 to 2019. Biological invasion costs were split relatively evenly between aquatic (US$ 1.16 billion; $MXN 21.95 billion) and terrestrial (US$ 1.17 billion; $MXN 22.14 billion) invaders, but semi-aquatic taxa dominated (US$ 2.99 billion; $MXN 56.57 billion), with costs from damages to resources four times higher than those from management of IAS (US$ 4.29 billion vs. US$ 1.04 billion; $MXN 81.17 billion vs $MXN 19.68 billion). The agriculture sector incurred the highest costs (US$ 1.01 billion; $MXN 19.1 billion), followed by fisheries (US$ 517.24 million; $MXN 9.79 billion), whilst most other costs simultaneously impacted mixed or unspecified sectors. When defined, costs to Mexican natural protected areas were mostly associated with management actions in terrestrial environments, and were incurred through official authorities via monitoring, control or eradication. On natural protected islands, mainly mammals were managed (i.e. rodents, cats and goats), to a total of US$ 3.99 million, while feral cows, fishes and plants were mostly managed in protected mainland areas, amounting to US$ 1.11 million in total. Pterygoplichthys sp. and Eichhornia crassipes caused the greatest reported costs in unprotected aquatic ecosystems in Mexico, and Bemisia tabaci to terrestrial systems. Although reported damages from invasions appeared to be fluctuating through time in Mexico, management spending has been increasing. These estimates, albeit conservative, underline the monetary pressure that invasions put on the Mexican economy, calling for urgent actions alongside comprehensive cost reporting in national states such as Mexico.

Alien animals cause drastic and negative impacts on biota and ecosystems. The feral donkey Equus asinus is an invasive alien species in Saudi Arabia. Damage of farms and plant consumed by feral donkeys were studied in the area between Al-Ula and Al-Wajh governorates in order to spot their harmful effects in this region and to propose possible solutions to the problems they caused. Surveys and direct interviews and conversations with farmers and villagers were the selected methods used to collect information. Prevention, and management actions were suggested to decrease numbers of feral donkeys. A useful investment potential was proposed to get some benefits from them.

Invasive plants had raised lots of concern about the environment and biodiversity. Many members of Asteraceae are notorious invasive alien species across the world. In Taiwan, Emilia (Asteraceae) contains one native and two naturalized species. Recently, we found some morphologically intermediate individuals between the native E. sonchifolia var. javanica and the alien E. praetermissa from northern Taiwan where the latter two grow sympatrically. Based on morphological comparisons, pollen viability and flow cytometry information, we confirmed the fact of natural hybridization. Herein, we describe a new hybrid Emilia ×latens J.-Y Wang & J.-C. Wang and provide a key to Emilia species in Taiwan.

<em>Abstract.</em>—In Japan, natural populations of three snakeheads have been established: Northern Snakehead <em>Channa argus</em>, Blotched Snakehead <em>C. maculata</em>, and Small Snakehead <em>C. asiatica</em>. Historical literature indicates that <em>C. argus </em>was brought into Japan during the period of national isolation in the early modern period. After the nation’s closure period, the former two species were introduced before World War II for food resources, whereas the last was found in Japan after the war. <em>Channa argus </em>was cultured in irrigation ponds in some prefectures, but ecological invasiveness was a concern because of their predatory nature and nonindigenous origins. When new national legislation controlling invasive alien species began in 2005, three snakeheads appeared on the list of alien species requiring special attention. However, there is little evidence suggesting ecological invasiveness of snakeheads in Japan in recent years. The most recent national list of invasive species in 2016 included no snakeheads. In some water bodies, <em>C. argus </em>is actively used as the ecological agent to control other invasive alien species.

Impact On Biodiversity

Marine invasive alien species are sea-based organisms that are non-native to a marine ecosystem, and which can or have spread to a degree that has an adverse impact on biodiversity and human livelihoods. In a globalized and inter-connected world, the threats posed by marine invasive alien species are here to stay. Accordingly, it often has been lamented that the threats from marine alien species are too difficult to combat effectively. In Australia, these threats are exacerbated by the country's unique characteristics such as its sheer size, as well as its geographical and historical isolation from the rest of the world. More importantly for the purposes of this article, Australia's unique constitutional framework that entrenches its national system of federalism has led to complex power-sharing arrangements between the Commonwealth, and the State and Territory governments in the management of invasive alien species, which are arguably inadequate to combat marine invasive alien species effectively. In Australia, laws have been made to manage only one vector of marine invasive species, ballast water from vessels, but not for other vectors. This article analyses how marine invasive alien species are currently managed within the Australian legal framework, and discusses what can be done to improve the status quo in order effectively to control the spread of such foreign organisms. It argues with optimism that marine invasive alien species can be effectively managed under a strong legal framework that seeks to prevent their occurrence and minimize the negative impacts of their occurrence. Such a legal framework consists of sound domestic laws and institutions, the effects of which can be enhanced by greater international cooperation.
