Massive economic costs of biological invasions despite widespread knowledge gaps: a dual setback for India

Biological Invasions, Journal Year: 2022, Volume and Issue: 24(7), P. 2017 - 2039

Published: April 5, 2022

Abstract Biological invasions are one of the top drivers ongoing biodiversity crisis. An underestimated consequence is enormity their economic impacts. Knowledge gaps regarding costs produced by invasive alien species (IAS) pervasive, particularly for emerging economies such as India—the fastest growing economy worldwide. To investigate, highlight and bridge this gap, we synthesised data on IAS in India. Specifically, examine how distributed spatially, environmentally, sectorally, taxonomically, temporally, across introduction pathways; discuss Indian vary with socioeconomic indicators. We found that have cost between at least US$ 127.3 billion to 182.6 (Indian Rupees ₹ 8.3 trillion 11.9 trillion) over 1960–2020, these increased time. Despite massive recorded costs, most were not assigned specific regions, environments, sectors, types causal IAS, knowledge more pronounced India than rest world. When specifically assigned, maximum incurred West, South North India, insects semi-aquatic ecosystems; they mainly public social welfare sector, associated damages losses rather management expenses. Our findings indicate reported grossly underestimate actual especially considering expected given India’s population size, gross domestic product high numbers without costs. This analysis improves our negative impacts biological burden can represent its development. hope study motivates policymakers address socio-ecological issues launch a national invasion research programme, since growth will be accompanied greater global change.

Unveiling the hidden economic toll of biological invasions in the European Union

Environmental Sciences Europe, Journal Year: 2023, Volume and Issue: 35(1)

Published: June 8, 2023

Abstract Background Biological invasions threaten the functioning of ecosystems, biodiversity, and human well-being by degrading ecosystem services eliciting massive economic costs. The European Union has historically been a hub for cultural development global trade, thus, extensive opportunities introduction spread alien species. While reported costs biological to some member states have recently assessed, ongoing knowledge gaps in taxonomic spatio-temporal data suggest that these were considerably underestimated. Results We used latest available cost InvaCost (v4.1)—the most comprehensive database on invasions—to assess magnitude this underestimation within via projections current future invasion macroeconomic scaling temporal modelling approaches project information over taxa, space, time, thereby producing more complete estimate economy. identified only 259 out 13,331 (~ 1%) known invasive species Union.

Invasive hematophagous arthropods and associated diseases in a changing world

Parasites & Vectors, Journal Year: 2023, Volume and Issue: 16(1)

Biological invasions have increased significantly with the tremendous growth of international trade and transport. Hematophagous arthropods can be vectors infectious potentially lethal pathogens parasites, thus constituting a growing threat to humans-especially when associated biological invasions. Today, several major vector-borne diseases, currently described as emerging or re-emerging, are expanding in world dominated by climate change, land-use change intensive transportation humans goods. In this review, we retrace historical trajectory these better understand their ecological, physiological genetic drivers impacts on ecosystems human health. We also discuss arthropod management strategies mitigate future risks harnessing ecology, public health, economics social-ethnological considerations. Trade transport goods materials, including vertebrate introductions worn tires, historically been important introduction pathways for most prominent invasive hematophagous arthropods, but sources likely diversify globalization. Burgeoning urbanization, urban heat island effect interact favor diseases they vector. To novel disease outbreaks, stronger preventative monitoring transboundary surveillance measures urgently required. Proactive approaches, such use engagement citizen science, would reduce epidemiological ecological could save millions lives billions dollars spent control management.

Recent advances in availability and synthesis of the economic costs of biological invasions

BioScience, Journal Year: 2023, Volume and Issue: 73(8), P. 560 - 574

Published: Aug. 1, 2023

Biological invasions are a global challenge that has received insufficient attention. Recently available cost syntheses have provided policy- and decision makers with reliable up-to-date information on the economic impacts of biological invasions, aiming to motivate effective management. The resultant InvaCost database is now publicly freely accessible enables rapid extraction monetary information. This facilitated knowledge sharing, developed more integrated multidisciplinary network researchers, forged collaborations among diverse organizations stakeholders. Over 50 scientific publications so far used detailed assessments invasion costs across geographic, taxonomic, spatiotemporal scales. These studies important can guide future policy legislative decisions management while simultaneously attracting public media We provide an overview improved availability, reliability, standardization, defragmentation costs; discuss how this enhanced science as discipline; outline directions for development.

Global freshwater fish invasion linked to the presence of closely related species

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: Feb. 15, 2024

Abstract In the Anthropocene, non-native freshwater fish introductions and translocations have occurred extensively worldwide. However, their global distribution patterns factors influencing establishment remain poorly understood. We analyze a comprehensive database of 14953 species across 3119 river basins identify hotspots for exotic translocated fishes. show that both types fishes are more likely to occur when closely related native This finding is consistent measures phylogenetic relatedness, biogeographical realms, highly invaded countries, even after accounting influence diversity. contradicts Darwin’s naturalization hypothesis, suggesting presence close relatives often signifies suitable habitats than intensified competition, predicting species. Our study provides assessment correlates, laying groundwork understanding future invasions in ecosystems.
