“…Despite effects of pesticides occurring in both grassland and agricultural wetlands, emergence was 74% lower in wetlands surrounded by crops than in grassland wetlands in 1 yr of the present study. Because the Prairie Pothole Region is climatically harsh, chemically complex, and replete with multiple stressors, aquatic insect responses to any one stressor are often hard to detect (Euliss et al 1999; Tangen et al 2003; Paquette et al 2013; Henry et al 2020). Results from our PCA did not indicate general differences between agricultural and grassland wetlands in 2016.…”

“…Loss of insect emergence in agriculturally influenced landscapes may negatively impact insectivorous consumers, including spiders, birds, bats, and amphibians (Mann et al 2009; Paquette et al 2013; Stahlschmidt et al 2017; Graf et al 2019; Henry et al 2020; Lewis‐Philips et al 2020). The negative effects of agriculture and insecticide accumulation on adult aquatic insect emergence suggested by our study (73% lower emergence from agricultural than grassland wetlands in 2016; 43% lower emergence over gradient of insecticide accumulation) are certainly within the range previously reported to affect consumers.…”

“…At least half of the original 8 million hectares of wetlands have been converted to crop production to take advantage of this fact (Euliss et al 1999). The remaining wetlands are often impacted by agricultural practices leading to elevated sedimentation rates, drift of agricultural chemicals, inputs of nutrients, altered vegetative communities, and drainage (Euliss et al 1999; Henry et al 2020). Wetlands in this region are mainly temporarily, seasonally, or semipermanently ponded (Euliss et al 1999).…”

Contaminants alter the quantity and quality of insect prey available to terrestrial insectivores. In agricultural regions, the quantity of aquatic insects emerging from freshwaters can be impacted by insecticides originating from surrounding croplands. We hypothesized that, in such regions, adult aquatic insects could also act as vectors of pesticide transfer to terrestrial food webs. To estimate insect-mediated pesticide flux from wetlands embedded in an important agricultural landscape, semipermanetly and temporarily ponded wetlands were surveyed in cropland and grassland landscapes across a natural salinity gradient in the Prairie Pothole Region of North Dakota (USA) during the bird breeding season in 2015 and 2016 (n = 14 and 15 wetlands, respectively). Current-use pesticides, including the herbicide atrazine and the insecticides bifenthrin and imidacloprid, were detected in newly emerged insects. Pesticide detections were similar in insects emerging from agricultural and grassland wetlands. Biomass of emerging aquatic insects decreased 43%, and insectmediated pesticide flux increased 50% along the observed gradient in concentrations of insecticides in emerging aquatic insects (from 3 to 577 ng total insecticide g -1 insect). Overall, adult aquatic insects were estimated to transfer between 2 and 180 µg total pesticide wetland -1 d -1 to the terrestrial ecosystem. In one of the 2 study years, biomass of emerging adult aquatic insects was also 73% lower from agricultural than grassland wetlands and was dependent on salinity. Our results suggest that accumulated insecticides reduce the availability of adult aquatic insect prey for insectivores and potentially increase insectivore exposure to insect-borne pesticides. Adult aquatic insects retain pesticides across metamorphosis and may expose insectivores living near both agricultural and grassland wetlands to dietary sources of toxic chemicals.

“…With widespread interest in Se biofortification, it is possible that the environment (i.e., soil, water, air, and plants) might become contaminated with Se due to extensive Se applications, which in turn could create a risk for human health [28,210] (Figure 2). The main anthropogenic sources of Se-pollution include agricultural and industrial activities [211][212][213]. The most serious problem resulting from Se-pollution is contamination of drinking water sources; hence, remediation requires effective techniques to remove Se from natural waters [214,215].…”

Selenium is an essential micronutrient required for the health of humans and lower plants, but its importance for higher plants is still being investigated. The biological functions of Se related to human health revolve around its presence in 25 known selenoproteins (e.g., selenocysteine or the 21st amino acid). Humans may receive their required Se through plant uptake of soil Se, foods enriched in Se, or Se dietary supplements. Selenium nanoparticles (Se-NPs) have been applied to biofortified foods and feeds. Due to low toxicity and high efficiency, Se-NPs are used in applications such as cancer therapy and nano-medicines. Selenium and nano-selenium may be able to support and enhance the productivity of cultivated plants and animals under stressful conditions because they are antimicrobial and anti-carcinogenic agents, with antioxidant capacity and immune-modulatory efficacy. Thus, nano-selenium could be inserted in the feeds of fish and livestock to improvise stress resilience and productivity. This review offers new insights in Se and Se-NPs biofortification for edible plants and farm animals under stressful environments. Further, extensive research on Se-NPs is required to identify possible adverse effects on humans and their cytotoxicity.

“…While wetland habitat loss has obvious impacts to aquatic species, the loss of emerging insects as prey for some birds and other predators presents a major concern (Wesner et al 2019). Additionally, these drainage systems typically lead to larger permanent wetlands carrying any nutrients and pesticides from the cropland along with them (Henry et al 2019). The overall effect of these contaminants on aquatic subsidies to grasslands systems is still largely unknown.…”
