The Asian ladybird Harmonia axyridis is an invasive species that is rapidly spreading around the world. Occupying new territories, H. axyridis often causes a decrease in the biodiversity of native species of coccinellids, competing with them for food resources. A comparison of H. axyridis with six species of ladybirds was made in terms of the ratio of the number of individuals and the degree of infestation with parasitoids. In Moscow city, the most widespread species of ladybirds was Adalia bipunctata (67.1%), H. axyridis ranks second (16.5%). The total infestation of H. axyridis pupae with parasitoids is 1.8% in Moscow city and 12.2% in Yalta city. Infestation with parasitoids of other ladybird species in Moscow city is much higher: from 11.0% to 36.4%. Thus, parasitoids effectively regulate the number of native ladybird species, but have an insignificant effect on the number of the invasive species H. axyridis .

The wild boar is one of the most dangerous invasive species. It is widespread in the world, including records for many Brazilian states. However, there is a lack of record from Maranhão state. In the present study, we reported a population of wild boar inside the Lençóis Maranhenses National Park, in Barrerinhas county, State of Maranhão. We discuss about the negative effects of this introduction on native species, including a record of predation by wild boar in nests of endangered turtles.

Abstract Russelia equisetiformis is a shrub that is widely cultivated around the world (PROTA. 2016). It is listed as an invasive and a transformer species in Cuba (Oviedo Prieto et al., 2012). In Oceania it is reported as an invasive species that has escaped from cultivation in Fiji, French Polynesia, Kiribati, New Caledonia, Niue and Palau (PIER, 2016). In Florida it is regarded by Florida's Exotic Pest Plant Council as a category III species; a widespread species that has the potential to form dense monocultures, primarily on disturbed sites (FLEPPC, 1993). It is regarded as a low risk species in Hawaii (Bezona et al., 2009).

Cane Toads are an invasive species in Florida and in many countries around the world. They have been established in Florida since the 1950s and have now spread to human-modified habitat throughout much of South and Central Florida. Cane Toads are larger and more poisonous than Florida's native toads; they can be fatal to dogs that try to eat them, and more research is necessary to understand their impacts on Florida's native species. This document covers the history of Cane Toads in Florida and how to distinguish them from native species.  It describes their ecology and impacts on both ecosystems and people. Finally, it provides advice for dealing with Cane Toads in yards and neighborhoods.

Aquatic Invasions

Invasive species are one of the most destructive environmental problems facing the world today. They can alter habitats, cause local extinction of native species, and have enormous economic impacts. Because ballast water is the primary source of aquatic invasions, the International Maritime Organization has recently passed regulations that will require ocean-going vessels to treat water prior to discharge. It has proven challenging, however, to find an environmentally friendly treatment that is effective at reducing the potential for invasions and yet also acceptable to the shipping industry in terms of safety, time and cost. Our work has focused on evaluations of deoxygenation in general, and Venturi Oxygen Stripping in particular, because of its ability to kill ballast water organisms and to reduce ballast tank corrosion. Results to date suggest that this approach has the potential to be an effective ballast water treatment option.

Invasive species pose considerable harm to native ecosystems and biodiversity and frustrate and at times fascinate the invasive species management and scientific communities. Of the numerous non-native species established around the world, only a minority of them are invasive and noxious, whereas the majority are either benign or in fact beneficial. Agriculture in North America, for example, would look dramatically different if only native plants were grown as food crops and without the services of the European honey bee as a pollinator. Yet the minority of species that are invasive negatively alter ecosystems and reduce the services they provide, costing governments, industries, and private citizens billions of dollars annually. In this review, I briefly review the consequences of invasive species and the importance of remaining vigilant in the battle against them. I then focus on their management in an increasingly connected global community.

Managing the impacts of invasive predators on islands is a priority for conserving global biodiversity. However, large islands and islands with substantial human settlement present particular challenges that can be broadly categorised as social and logistical. Around the world, managers concerned with island biodiversity are tackling increasingly ambitious projects, and some examples from Japan and New Zealand have been at the forefront. We used dialogues with managers, researchers, and community members, as well as our respective experience as wildlife researchers in Japan and New Zealand, to compare the challenges faced by wildlife managers in each country. We note similarities and differences between the two countries, and identify lessons from each that will help advance invasive species management on islands globally. Our observations from Japan and New Zealand show that considerable progress has been made in managing invasive predators on large, inhabited islands. Further progress will require more effective engagement with island residents to promote the goals of invasive species management, to find common ground, and to ensure that management is socially and culturally acceptable.

Permanent Increase

The three species of the genus Mus mentioned above follow in the wake of civilised man and may be looked upon as more or less domestic animals. Moreover, when they appear in any new locality, they seem to possess the power of eliminating the previously established native species of rats and mice, and they thus obtain for themselves a wider field and the opportunity for a rapid permanent increase in number of individuals. Of the three, Mus rattus alone habitually infests ships, but by accidental transference in vessels from port to port all three have become distributed throughout the world. Australia is especially rich in peculiar local species of rats, abundantly distinct from, but to some extent resembling, Mus rattus. This circumstance renders it not improbable that on occasion animals from Australia may have been incorrectly identified with that cosmopolitan species.
