Arthropods represent an entry point for pesticide transfers in terrestrial food webs, and accumulation upper chain organisms, such as predators can have cascading consequences on ecosystems. However, the mechanisms driving transfer bioaccumulation webs remain poorly understood. Here we review literature mediated by arthropods webs. The of pesticides their potential biomagnification are related to chemical properties toxicokinetic substances, resistance detoxification abilities contaminated well effects organisms' life history traits. We further identify four critical areas which knowledge gain would improve future predictions impacts First, efforts should be made regarding co-formulants mixtures that currently understudied. Second, progress sensitivity analytical methods allow detection low concentrations small individual arthropods. Quantifying preys, predators, or vertebrates at higher trophic level bring crucial insights into real-world Finally, quantifying influence structure complexity communities could address several important sources variability across species This narrative will inspire studies aiming quantify better capture ecological natural cultivated landscapes.

Linking human impacts to community processes in terrestrial and freshwater ecosystems

Ecology Letters, Год журнала: 2022, Номер 26(2), С. 203 - 218

Human impacts such as habitat loss, climate change and biological invasions are radically altering biodiversity, with greater effects projected into the future. Evidence suggests human may differ substantially between terrestrial freshwater ecosystems, but reasons for these differences poorly understood. We propose an integrative approach to explain by linking four fundamental processes that structure communities: dispersal, speciation, species-level selection ecological drift. Our goal is provide process-based insights why impacts, responses across ecosystem types using a mechanistic, eco-evolutionary comparative framework. To enable insights, we review synthesise (i) how influence diversity dynamics in versus communities, specifically whether relative importance of each process differs among (ii) pathways which can produce divergent due strength ecosystems identify. Finally, highlight research gaps next steps, discuss this new conservation. By focusing on shape aim mechanistically link ongoing future changes ecosystems.

Contaminant fluxes across ecosystems mediated by aquatic insects

Metals and organic contaminants in aquatic systems affect the coupling of terrestrial ecosystems through two pathways: contaminant-induced effects on insect emergence emergence-induced contaminant transfer. Consequently, impact can be driven by modifications quantity quality adult insects serving as prey or entering food webs part diet predators. Here, we provide an overview recent advances field, separating metals from due to their differential propensity bioaccumulate thus potential contribution either pathways. Finally, this review highlights knowledge gap relative these pathways insectivores.

Emerging Midges Transport Pesticides from Aquatic to Terrestrial Ecosystems: Importance of Compound- and Organism-Specific Parameters

Environmental Science & Technology, Год журнала: 2022, Номер 56(9), С. 5478 - 5488

Emerging aquatic insects have the potential to retain contaminants after metamorphosis, potentially transporting them into adjacent terrestrial food webs. It is unknown whether this transfer also relevant for current-use pesticides. We exposed larvae of nonbiting midge, Chironomus riparius, a sublethal pulse mixture nine moderately polar fungicides and herbicides (logKow 2.5–4.7) at three field treatment levels (1.2–2.5, 17.5–35.0, or 50.0–100.0 μg/L). then assessed pesticide bioaccumulation bioamplification over full aquatic–terrestrial life cycle both sexes including egg laying adult females. By applying sensitive LC–MS/MS analysis small sample volumes (∼5 mg, dry weight), we detected all pesticides in from (2.8–1019 ng/g), five adults lowest level eight higher (1.5–3615 ng/g). Retention through metamorphosis was not predictable based solely on lipophilicity. Sex-specific differences insect concentrations were significant pesticides, with greater females four them. Over duration adults' lifespan, generally decreased while persisting males. Our results suggest that low moderate daily dietary exposure these may be possible tree swallow nestlings insectivorous bats.

Anthropogenic stressors can affect the emergence of aquatic insects. These insects link and adjacent terrestrial food webs, serving as high-quality subsidy to consumers, such spiders. While previous studies have demonstrated that changes in biomass timing may propagate across ecosystem boundaries, physiological consequences altered quality for spiders are largely unknown. We used a model chain study potential effects quality: Tetragnatha spp. were exclusively fed with emergent Chironomus riparius cultured absence or presence either copper (Cu), Bacillus thuringiensis var. israelensis (Bti), mixture synthetic pesticides paired two basal resources (Spirulina vs. TetraMin®) differing terms fatty acid (FA) composition. Basal shaped FA profile chironomids, whereas their effect on decreased, presumably due capacity both chironomids modify (dietary) FA. In contrast, contaminants had negligible prey profiles but reduced content physiologically important polyunsaturated FAs, 20:4n-6 (arachidonic acid) 20:5n-3 (eicosapentaenoic acid), by approximately 30% Cu Bti treatments. This contributed statistically significant decline (40%-50%) spider growth. The observed likely related nutritional because consumption was, our experimental design, constant. Analyses additional parameters describe consumers proteins, carbohydrates, retention shed further light underlying mechanisms.
