1 Ιαν 2017 · We review empirical studies on how bioinvasions alter food webs and how a food-web perspective may change their prediction and management. Predation is found to underlie the most spectacular damage in invaded systems, sometimes cascading down to primary producers.

11 Δεκ 2020 · Currently, the indicators used to measure the effectiveness of raccoon management are mainly the extent of crop damage, the capture effort, the number of captures, and capture per unit effort (CPUE), which is calculated from the two latter indicators.
As opportunistic feeders, they play a vital role in the food web by consuming a wide variety of prey, including insects, small mammals, birds, fish, amphibians, reptiles, fruits, nuts, and vegetables. Raccoons help control populations of certain species and serve as both predator and prey in the ecosystem.
21 Ιουλ 2020 · The raccoon is an opportunistic mesocarnivore native to North and Central America that, despite its preference for riparian forests (Heske and Ahlers 2016; Duscher et al. 2018; Fiderer et al. 2019), can adapt to new environments exploiting a wide variety of habitat and food resources (Prange et al. 2004).
16 Μαρ 2017 · Previous rabies variant elimination in raccoons (Canada), foxes (Europe), and dogs and coyotes (United States) demonstrates that elimination of the raccoon variant from the eastern US is feasible, given an understanding of rabies control costs and benefits and the availability of proper tools.
10 Μαρ 2018 · The northern raccoon (Procyon lotor) is an invasive species in Europe and poses a serious threat to indigenous biodiversity and human health. Raccoons can also cause important economic losses. Despite the risks, no comprehensive report on the raccoon status in Europe is available.
