Significance Survey data show a large-scale decline in insects. This global is often linked to human actions intensive agricultural areas. To investigate whether this has causal relationship with neonicotinoid insecticides, we performed an outdoor experiment representative surface water concentrations of the thiacloprid. We exposed naturally formed aquatic communities increasing and monitored insect emergence during 3-mo period. that strongly decreased abundance biomass five major orders...
Abstract Dragonflies (Odonata) are ancient and familiar insects with a deep strong cultural association humans. They have an aquatic larval stage aerial adult stage, meaning that they respond to ecological conditions in both freshwater the adjacent land surface. Currently, 16% of dragonflies threatened. Overall, face several threats, especially habitat loss, landscape transformation, pollution, altered hydrology, spread invasive alien species, as well certain geographic‐specific threats....
Many species suffer from anthropogenic habitat fragmentation. The resulting small and isolated populations are more prone to extinction due to, amongst others, genetic erosion, inbreeding depression Allee-effects. Genetic rescue can help mitigate such problems, but might result in outbreeding depression. We evaluated offspring fitness after selfing outcrossing within among three very remnant of the heterostylous plant Primula vulgaris. used greenhouse-grown these test several components. One...
It is essential to understand effects of existing and emerging anthropogenic stressors on the structure aquatic food webs in more natural settings, obtain realistic predictions how they can affect major ecosystem properties functioning. We therefore examined whether 1) concentrations key agricultural pesticides nutrients induce shifts trophic linkages 2) observed changes are qualitatively different between green (algal-based) brown (detritus-based) part web. To this end, we exposed a...
The neonicotinoid acetamiprid is used as a foliar insecticide spray, which results in direct exposure of wide variety soil organisms. Laboratory testing indicated that toxic to the Collembola (springtails) species Folsomia candida, while Acari (mites) seem relatively insensitive neonicotinoids. Since such opposing effects on different arthropods might imbalance natural arthropod communities, this study determined: (i) if field-realistic doses affect abundance and diversity (ii) whether these...
Although it is widely acknowledged that a decline of freshwater biodiversity jeopardizes the functioning ecosystems, large number (human-induced) pressures jointly acting on these systems hampers managing its biodiversity. To disentangle magnitude and temporal effects single interacting pressures, experiments are required study how affect structuring natural communities. We performed with naturally assembled invertebrate communities in 36 experimental ditches to assess joint environmentally...
Adequate predictions of mosquito-borne disease risk require an understanding the relevant drivers governing mosquito populations. Since previous studies have focused mainly on role temperature, here we assessed effects other important ecological variables (predation, nutrient availability, presence conspecifics) in conjunction with temperature life history parameters. We carried out two mesocosm experiments common brown house mosquito, Culex pipiens, a confirmed vector for West Nile Virus,...
Abstract Freshwaters are among the most endangered ecosystems in world as a result of anthropogenic interference such pollution. Pollution form neonicotinoids has been intensively studied, but data thus far is often conflicted by contrasting responses between laboratory and field experiments. In addition, toxicity scarce contradictory for insects Odonates (dragonflies damselflies) potential risk to them may therefore be overlooked. We investigate exposing nymphs blue‐tailed damselfly...
Background Microorganisms govern important ecosystems processes, in particular the degradation of organic matter (OM). However, microorganisms are rarely considered efforts to monitor ecosystem health and functioning. Evidence suggests that environmental perturbations can adversely affect microbial communities their ability use available substrates. whether impacted efficiencies extracting utilizing resources (resource niche breadth) translate changes OM natural systems remains poorly...
Abstract Many studies show that neonicotinoid insecticides cause toxicity to aquatic invertebrates. Some report insecticide may differ in combination with other agrochemicals under realistic field conditions. To explore such altered further, we aimed determine the single and combined effects of environmentally relevant levels thiacloprid nutrients on different endpoints 4 invertebrate species. Animals were exposed these using a caged experiment within experimental ditches. We observed...
Freshwater habitats are under stress from agricultural land use, most notably the influx of neonicotinoid pesticides and increased nutrient pressure fertilizer. Traditional studies investigating effects stressors on freshwater systems often limited to a narrow range taxa, depending heavily morphological expertise. Additionally, disentanglement multiple simultaneous can be difficult in field studies, whereas controlled laboratory conditions do not accurately reflect natural food webs. To...
Abstract Temperate aquatic communities are highly diverse and seasonally variable, due to internal biotic processes environmental drivers, including human‐induced stressors. The impact of drivers on species abundance is supposed differ fundamentally depending whether populations experiencing limitations, which may shift over the season. However, an integrated understanding how structure currently lacking. In order partition effect we used random forests quantify interactions between all taxa...
Abstract There is a widespread concern that we are witnessing an ongoing homogenisation of ecological communities. However, in contrast to human impacts on spatial patterns biodiversity, the temporal aspects β‐diversity have received little attention. Moreover, interplay between and poorly understood. To address this knowledge gap, assessed dissimilarity within freshwater macrofaunal communities drainage ditches determine spatiotemporal as well relation different types land use. We...
Evidence grows that standard toxicity testing might underestimate the environmental risk of neurotoxic insecticides. Behavioural endpoints such as locomotion and mobility have been suggested sensitive ecologically relevant additions to tested endpoints. Possible interactive effects chemicals additional stressors are typically overlooked in standardised testing. Therefore, we aimed investigate how concurrent exposure (increased temperature predation cues) a nicotinic acetylcholine receptor...
The increasing environmental abundance of reactive N ('Nr') entails many adverse effects for society such as soil degradation and eutrophication. In addressing the global surplus N, there is a pressing need to quantify local sources dynamics Nr. Although quantified an important anthropogenic source Nr, spatiotemporal patterns ammonia ('NH3') emitted by dairy farming its resulting pressure on surface waters lacks quantification. Quantification could optimize farm management with minimized...
Abstract Decadal declines in aquatic ecosystem health prompted monitoring efforts and studies on effects of human practices biodiversity, yet a consideration ecological processes trophic linkages is increasingly required to develop an in-depth understanding food webs its vulnerability activities. Here, we test laboratory incubations using natural organic matter whether agricultural have effect two interacting (i.e., decomposition invertebrate growth) as the relevant temporal components...
