The global increase in biological invasions is placing growing pressure on the management of ecological and economic systems. However, effectiveness current expenditure difficult to assess due a lack standardised measurement across spatial, taxonomic temporal scales. Furthermore, there no quantification spending difference between pre-invasion (e.g. prevention) post-invasion control) stages, although preventative measures are considered be most cost-effective.

Aliens in caves: the global dimension of biological invasions in subterranean ecosystems

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Journal Year: 2023, Volume and Issue: 98(3), P. 849 - 867

Published: Jan. 20, 2023

Alien species are a significant threat to natural ecosystems and human economies. Despite global efforts address this challenge, the documented number of alien is rapidly increasing worldwide. However, magnitude impact may vary significantly across habitats. For example, some habitats naturally less prone biological invasions due stringent abiotic biotic characteristics, selecting for limited introduced possessing traits closely related native organisms. Subterranean quintessential examples with strong environmental filters (e.g. lack light scarcity food), driving convergent adaptations in that have successfully adapted life darkness. these constraints, records subterranean has increased recent decades, but relevant literature remains largely fragmented mostly anecdotal. Therefore, even though caves generally considered very fragile ecosystems, their susceptibility impacts by untested other than specific cases.

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.

Ants evade harmful food by active abandonment

Communications Biology, Journal Year: 2024, Volume and Issue: 7(1)

Published: Jan. 12, 2024

Invasive ants, such as the Argentine ant, pose a severe economic and ecological threat. Despite advancements in baiting techniques, effectively managing established ant populations remains daunting challenge, often ending failure. Ant colonies employ behavioural immunity against pathogens, raising question of whether ants can collectively respond to toxic baits. This study investigates actively abandon palatable but harmful food sources. We provided two sucrose feeders, each generating new foraging trail, with one transitioning offering food. Six hours later, activity on that path decreases, while non-toxic trunk trail unaffected, excluding factors like population decline or satiation reasons for decline. Laboratory experiments confirmed remained alive six after ingesting presence low days, gradually decreasing along nearest section trail. abandonment behaviour minimises entry into nest, acting protective social mechanism. The evasion bait-treated areas likely contributes considerably control failures. Understanding response baits is essential developing effective strategies combat invasive species.
