Summary Predictions of the identities and ecological impacts invasive alien species are critical for risk assessment, but presently we lack universal standardized metrics that reliably predict likelihood degree impact such invaders (i.e. measurable changes in populations affected species). This need is especially pressing emerging potential future have no invasion history. Such a metric would also ideally apply across diverse taxonomic trophic groups. We derive new invader blends: (i)...
Abstract Invasive species management requires allocation of limited resources towards the proactive mitigation those that could elicit highest ecological impacts. However, we lack predictive capacity with respect to identities and degree impacts invasive species. Here, combine relative per capita effects field abundances invader as compared native into a new metric, “Relative Impact Potential” (RIP), test whether this metric can reliably predict high impact invaders. This tests invaders...
Some parasites are expected to have beneficial impacts on wild populations in polluted environments because of their bioaccumulation potential pollutants from hosts. The fate organic micropollutants host–parasite systems and the combined effect parasitism pollution were investigated chub Squalius cephalus, a freshwater fish, infected (n = 73) or uninfected 45) by acanthocephalan Pomphorhynchus sp. differently contaminated riverine sites. Several ubiquitous (polychlorinated biphenyls (PCBs),...
Abstract The influence of climate change on the ecological impacts invasive alien species (IAS) remains understudied, with deoxygenation aquatic environments often-overlooked as a consequence change. Here, we therefore assessed how oxygen saturation affects impact predatory fish, Ponto-Caspian round goby ( Neogobius melanostomus ), relative to co-occurring endangered European native analogue, bullhead Cottus gobio ) experiencing decline in presence IAS. In individual trials and mesocosms,...
Trophically-transmitted parasites often change the phenotype of their intermediate hosts in ways that increase vulnerability to definitive hosts, hence favouring transmission. As a "collateral damage", manipulated can also become easy prey for non-host predators are dead ends parasite, and which supposed play no role transmission strategies. Interestingly, infection with acanthocephalan parasite Polymorphus minutus has been shown reduce its gammarid predators, whose presence triggered...
Abstract Tolerance to human‐induced environmental stressors is known contribute the spread and success of invasive species but their response anthropogenic noise has still be explored. Anthropogenic might modulate trophic impact competitiveness against native species. We used an ecological approach through derivation functional test whether strength interaction between pumpkinseed sunfish Chaoborus larvae was influenced by motorboat noise, with or without pre‐exposure. Boat decreased maximum...
Anthropogenic noise has the potential to alter community dynamics by modifying strength of nested ecological interactions such as predation. Direct effects on per capita predation rates have received much attention but context in which occurs is often oversimplified. For instance, many animals interact with conspecifics while foraging and these nontrophic can positively or negatively influence rates. These are referred multiple-predator (MPEs). The extent modulate MPEs thereby indirectly...
Abstract Anthropogenic noise can affect animals physically, physiologically, and behaviourally. Although individual responses to are well documented, the consequences in terms of community structure, species coexistence, ecosystem functioning remain fairly unknown. The impact on predation has received a growing interest alterations trophic links observed when shift from foraging stress‐related behaviours, distracted by noise, or because acoustic masking. However, experimental procedures...
SUMMARY Among the potential effects of parasitism on host condition, ‘increased abilities’ hypothesis is a counterintuitive pattern which might be predicted in complex-life-cycle parasites. In case trophic transmission, parasite increasing its intermediate host's performance facing non-host predators improves probability transmission to an adequate, definitive host. present study, we investigated cost infection with acanthocephalan Polymorphus minutus locomotor/escape host, crustacean...
Trophically‐transmitted parasites are known for their ability to enhance predation of intermediate host but they less suppress predation. We review recent literature on manipulation explaining why and when in its life cycle a parasite benefits from preventing the host. Predation suppression occurs hosts as long larva has not reached developmental conditions allowing it successfully establish next (competency). also examine possibility that may occur harbouring competent larvae (post...
Parasites are omnipresent, and their eco‐evolutionary significance has aroused much interest from scientists. may affect hosts in many ways with changes density, appearance, behaviour energy content, likely to modify value predators (profitability) within the optimal foraging framework. Consequently, parasites could impact predators' diet trophic links through food webs. Here, we investigate consequences of infection by iridovirus Daphnia iridescent virus 1 (DIV‐1) on reproductive success,...
SUMMARY Trophically transmitted parasites are likely to strongly influence food web-structure. The extent which they change the trophic ecology of their host remains nevertheless poorly investigated and field evidence is lacking. This particularly true for acanthocephalan whose invertebrate hosts can prey on other invertebrates contribute leaf-litter breakdown. We used a multiple approach combining feeding experiments, neutral lipids stable isotopes investigate freshwater amphipod Gammarus...
Summary 1. First known for their shredding activity, freshwater amphipods also behave as active predators with consequences prey population regulation and amphipod coexistence in the context of biological invasions. 2. A way to quantify predation is determine average consumption rate per predator, its functional response (FR). 3. Although are gregarious can display social interactions that alter capita rates, previous studies using FR approach investigate ignored such potential mutual...
