Urbanization is an important driver of global change associated with a set environmental modifications that affect the introduction and distribution invasive non-native species (species populations transported by humans beyond their natural biogeographic range established are spreading in introduced range; hereafter, species). These recognized as cause large ecological economic losses. Nevertheless, impacts these urban areas still poorly understood.

While data on biological invasions and their economic toll are increasingly available, drivers of susceptibility to damage cost-effectiveness management in reducing long-term costs remain poorly understood. We used describing the of, expenditure on, invasive species among 56 nations between 2000 2020 reported InvaCost database test overarching hypothesis that higher-income those with higher trade volume have a efficiency limit incurred by spending relatively more management. also tested whether (i) corruption reduced capacity manage species, leading costs, (ii) educated citizens or greater technological scientific output allow for improved incentives ability thereby relative (iii) economies based primary resource dependencies (e.g., agriculture) at risk incurring high so all other conditions being equal, compared expenditure. By focusing ratio expenditure, we analyse willingness countries invest as function extent suffered. show activity, measured trade, is main determinant this — volume, smaller ratio. found rate increase damage:management country's proportion total land area devoted agriculture increased, suggesting dependency predisposes country from over time. When considering identified damage-related, results indicated government investment education produced proportional damage, lower both damage.

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.

The ratting of North America: A 350-year retrospective on Rattus species compositions and competition

Science Advances, Journal Year: 2024, Volume and Issue: 10(14)

Published: April 3, 2024

While the impacts of black ( Rattus rattus ) and brown norvegicus rats on human society are well documented—including spread disease, broad-scale environmental destruction, billions spent annually animal control—little is known about their ecology behavior in urban areas due to challenges studying animals city environments. We use isotopic ZooMS analysis archaeological (1550s–1900 CE) rat remains from eastern North America provide a large-scale framework for species arrival, interspecific competition, dietary ecology. Brown arrived earlier than expected rapidly outcompeted coastal areas. This replacement happened despite evidence that two occupy different trophic positions. Findings include earliest molecularly confirmed Americas show deep ecological structure how exploit human-structured areas, with implications understanding zoonosis, management, ecosystem planning as broader themes dispersal, phylogeny, evolutionary ecology, climate impacts.

Multi-stakeholder working groups to improve rodent management outcomes in agricultural systems

International Journal of Pest Management, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 17

Published: June 24, 2024

Rodent pests pose significant impacts to agricultural systems and public health globally. Effective strategies for sustainable management while minimizing environmental are crucial. To address the multifaceted nature of rodent impacts, well-coordinated initiatives necessary support control strategies, raise awareness among authorities, inform public. There is increasing global evidence Working Groups delivering successful a range natural resource issues. We outline three case study working groups tackle pests: (1) National Mouse Group in Australia manage mouse plague (2) Common Vole Management Germany common vole (3) FREDON network France. Each group evolved independently, but all have remarkably similar structures, including monitoring, modelling/forecasting, regular stakeholder meetings (including producers, researchers, government agency staff others), developing advice identifying research priorities. The success these was related to: broad engagement (particularly farmers/producers), dedicated funding conduct direct maintained momentum through phases population cycles, (4) benefit stakeholders. As rodenticides increasingly restricted, such will become more important future, because develop "toolboxes".
