Biological Invasions , Biological Diversity and Trade

چکیده
The opening of new markets or trade routes has resulted in the deliberate or accidental introduction of new species, while the growth in the volume of trade has increased the frequency of species introductions. We model the connection between landscape heterogeneity, resource extraction, the level of biodiversity, and the level of trade. We show that the invasion risks of trade reduce the socially optimal level of imports and harvesting effort. We identify a “paradox of globalization”: the higher the volume of trade, the greater the number of species introductions, the higher the “optimal tariff” on trade flows. JEL Classification: Q27, Q56, Q57.

Socio-economic drivers of biological invasions. A worldwide, bio-geographical analysis of trade flows and local environmental quality
The introduction of harmful non-indigenous species has long been acknowledged to depend both on the propagule pressure imposed by the openness to international trade, and on the health of the receiving ecosystem, largely determined by the level of anthropogenic disturbance due to local economic activities. We estimate the relative weight of the socio-economic drivers of biological invasions, fo...

متن کاملTemporal modelling of ballast water discharge and ship-mediated invasion risk to Australia
Biological invasions have the potential to cause extensive ecological and economic damage. Maritime trade facilitates biological invasions by transferring species in ballast water, and on ships' hulls. With volumes of maritime trade increasing globally, efforts to prevent these biological invasions are of significant importance. Both the International Maritime Organization and the Australian go...
متن کاملTrade, transport and trouble: managing invasive species pathways in an era of globalization
1. Humans have traded and transported alien species for millennia with two notable step-changes: the end of the Middle Ages and beginning of the Industrial Revolution. However, in recent decades the world has entered a new phase in the magnitude and diversity of biological invasions: the Era of Globalization. This Special Profile reviews the links between the main drivers of globalization and b...
متن کاملGenetic bottlenecks and successful biological invasions: the case of a recent Lessepsian migrant.
Our current understanding of the mechanisms that lead to successful biological invasions is limited. Although adaptations play a central role in biological invasions, genetic studies have so far failed to produce a unified theory. The bluespotted cornetfish, a recent Red Sea invader in the Mediterranean Sea via the Suez Canal, provides an ideal case study for research in the mechanisms of invas...
