The Emergency Recovery Plan for freshwater biodiversity recognizes that addressing nonnative species is one of six principal actions needed to bend the curve in loss. This because introduction rates continue accelerate globally and where these develop invasive populations, they can have severe impacts on biodiversity. most effective management measure protect prevent introductions species. Should a be introduced, however, then its early detection implementation rapid reaction measures avoid it establishing dispersing.

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

Biological Invasions, Год журнала: 2022, Номер 24(7), С. 2017 - 2039

Опубликована: Апрель 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.

A global synthesis and assessment of free-ranging domestic cat diet

Nature Communications, Год журнала: 2023, Номер 14(1)

Опубликована: Дек. 12, 2023

Free-ranging cats (Felis catus) are globally distributed invasive carnivores that markedly impact biodiversity. Here, to evaluate the potential threat of cats, we develop a comprehensive global assessment species consumed by cats. We identify 2,084 eaten which 347 (16.65%) conservation concern. Islands contain threefold more concern than continents do. Birds, reptiles, and mammals constitute ~90% consumed, with insects amphibians being less frequent. Approximately 9% known birds, 6% mammals, 4% reptile identified in cat diets. 97% <5 kg adult body mass, though much larger also eaten. The accumulation curves not asymptotic, indicating our estimates conservative. Our results demonstrate extreme generalist predators, is critical for understanding their on ecological systems developing management solutions.

Burmese pythons ( Python molurus bivittatus ) are native to southeastern Asia, however, there is an established invasive population inhabiting much of southern Florida throughout the Greater Everglades Ecosystem. Pythons have severely impacted species and ecosystems in represent one most intractable invasive-species management issues across globe. The difficulty stems from a unique combination inaccessible habitat cryptic resilient nature that thrive subtropical environment Florida, rendering them extremely challenging detect. Here we provide comprehensive review synthesis science relevant managing pythons. We describe existing control tools challenges productive research, identifying key knowledge gaps would improve future research decision making for python control.

Global economic costs of herpetofauna invasions

Scientific Reports, Год журнала: 2022, Номер 12(1)

Опубликована: Июль 28, 2022

Abstract Biological invasions by amphibian and reptile species (i.e. herpetofauna) are numerous widespread, having caused severe impacts on ecosystems, the economy human health. However, there remains no synthesised assessment of economic costs these invasions. Therefore, using most comprehensive database invasive alien worldwide (InvaCost), we analyse herpetofauna according to taxonomic, geographic, sectoral temporal dimensions, as well types costs. The cost totaled at 17.0 billion US$ between 1986 2020, divided split into 6.3 for amphibians, 10.4 reptiles 334 million mixed classes. were associated predominantly with only two (brown tree snake Boiga irregularis American bullfrog Lithobates catesbeianus ), 10.3 6.0 in costs, respectively. Costs remaining 19 reported relatively minor (< 0.6 US$), they entirely unavailable over 94% known worldwide. Also, positively correlated research effort, suggesting biases towards well-known taxa. So far, have been dominated predictions extrapolations (79%), thus empirical observations impact scarce. activity sector affected amphibians was authorities-stakeholders through management (> 99%), while reptiles, mostly damages sectors (65%). Geographically, Oceania Pacific Islands recorded 63% total followed Europe (35%) North America (2%). Cost reports generally increased time but peaked 2011 2015 2006 2010 reptiles. A greater effort studying is necessary a more complete understanding invasion species. We emphasise need control prevention policies concerning spread current future herpetofauna.

Tracking a killer shrimp: Dikerogammarus villosus invasion dynamics across Europe

Diversity and Distributions, Год журнала: 2022, Номер 29(1), С. 157 - 172

Опубликована: Ноя. 6, 2022

Abstract Aim Invasive alien species are a growing problem worldwide due to their ecological, economic and human health impacts. The “killer shrimp” Dikerogammarus villosus is notorious invasive amphipod from the Ponto‐Caspian region that has invaded many fresh brackish waters across Europe. Understandings of large‐scale population dynamics highly impactful invaders such as D. lacking, inhibiting predictions impact efficient timing management strategies. Hence, our aim was assess trends well its impacts in freshwater rivers streams. Location Methods We analysed 96 European time series between 1994 2019 identified relative abundance (i.e. dominance %) series, set site‐specific characteristics identify drivers determinants changes invasion using meta‐regression modelling. also looked at spread over space estimate speed (km/year) investigated on recipient community metrics abundance, taxa richness, temporal turnover, Shannon diversity Pielou evenness) generalized linear models. Results Population varied series. Nevertheless, increased all frequency occurrences (used proxy for invader spread) described by Pareto distribution, whereby we estimated lag phase introduction spatial expansion) approximately 28 years, followed gradual increase before new declined rapidly long term. change associated with decreased turnover diversity. Main Conclusion Our results show well‐established significantly alters ecological communities. However, multidecadal prior observed expansion suggests initial introductions cryptic, thus signalling need more effective early detection methods.

Biological invasions are increasingly recognised as a major global change that erodes ecosystems, societal well-being, and economies. However, comprehensive analyses of their economic ramifications missing for most national economies, despite rapidly escalating costs globally. Türkiye is highly vulnerable to biological owing its extensive transport network trade connections well unique transcontinental position at the interface Europe Asia. This study presents first analysis reported caused by in Türkiye. The InvaCost database which compiles invasive non-native species' monetary was used, complemented with cost searches specific Türkiye, describe spatial taxonomic attributes costly species, types costs, temporal trends. total attributed species (from 202 reporting documents) amounted US$ 4.1 billion from 1960 2022. data were only available 87 out 872 (10%) known Costs biased towards few hyper-costly taxa, such jellyfish, stink bugs, locusts. Among impacted sectors, agriculture bore highest cost, reaching 2.85 billion, followed fishery sector 1.20 billion. Management (i.e., control eradication) were, against expectations, substantially higher than damage (US$ 2.89 vs. 28.4 million). Yearly incurred rose exponentially over time, 504 million per year 2020-2022 predicted increase further next 10 years. A large deficit records compared other countries also shown, suggesting larger underestimate typically observed. These findings underscore need improved recording preventative management strategies reduce future post-invasion help inform decisions manage burdens posed species. insights emphasise crucial role standardised accurately estimating associated prioritisation communication purposes.

Опубликована: Янв. 24, 2025

Abstract Forecasting emergent pest spread is paramount to mitigating their impacts. For host-specialized pests, epidemiological models of through a single host population are well developed. However, most pests attack multiple species; the challenge predicting which communities vulnerable infestation. Here, we develop phylogenetically-informed approach predict establishment multi-host across heterogeneous landscapes. We model beetle-pathogen symbiotic complex on trees, introduced from Southeast Asia California. The phyloEpi for likelihood was predicted phylogenetic composition woody species in invaded community and influence temperature beetle reproduction. Plant dominated by close relatives known epidemiologically critical hosts were four times more likely become infested than with distantly related species. Where microclimate favored reproduction, greater expected based only composition. applied this infestation risk California using weather data complete tree inventories 9262 1-km 2 grids 170 cities. Regions state low confirmed independent monitoring. Analysts can adapt these ecology tools any novel habitats.
