Abstract Urbanization processes affect the accumulation of trace elements in urban soils. Due to rapid urbanization, are continuously emitted into soil and generate serious risk human health ecosystem. Therefore, effects urbanization on environmental quality along an gradient has emerged as important frontier research. We carried out this study assess distribution, pollution, potential ecological topsoil a typical Urumqi city, NW China. collected total 77 samples from urban, suburban, rural zones analyzed their concentrations nine elements: cadmium (Cd), cobalt (Co), copper (Cu), mercury (Hg), nickel (Ni), lead (Pb), antimony (Sb), vanadium (V), zinc (Zn). To estimate pollution elements, we employed load index ( PLI ) RI ). The results obtain indicated that concentrations, spatial distributions, levels, degrees investigated were closely correlated with process. distribution Cd, Co, Ni, Pb, Sb, V, Zn showed zonal pattern gradient. values decreased order > suburban rural, whereas suburban. Furthermore, considerable gradient, moderate zones, Hg poses most significant among elements. Overall, analysis is useful identify urbanization.

Whether soil heavy metal pollution contributes to the decline in pollinator populations remains inconclusive. Based on detection of metals nectar, pollen, and bodies pollinating insects areas affected by pollution, this study aimed investigate impact adding four metals-zinc (Zn), lead (Pb), copper (Cu), nickel (Ni)-at realistic concentrations diet pre-oviposition period, larval development production adult bees, weight worker bees. The sought evaluate influence accumulation mediated floral rewards key stages growth bumblebee (Bombus terrestris L.). Results revealed that Zn, Pb, Cu significantly extended period queen with Pb doubling time at high Ni showing no significant effect moderate low concentrations. Lead, Cu, medium concentrations, whereas Zn only had a reduced bee yield body bees different among which 25%-40%. concentration was most obvious, reduction 30%. Our findings support hypothesis rewards, can have serious some bumblebees.

Soil heavy metal contamination is often an unintended byproduct of historic land-use. This can negatively impact resident plants and their interactions with other organisms. Plant fitness in contaminated landscapes depends not only on plant growth, but also the maintenance pollinators. Cadmium (Cd) a that commonly found agricultural, urban, industrial ecosystems as legacy It prioritized pollutant soils because its wide distribution strong biotoxicity. To understand how Cd influences growth pollinator interactions, we grew sunflowers media three different concentrations to represent range faced by growing land recovering from past We measured effects sunflower morphology foraging behavior, specifically number visits visit duration. then seed weight determine if directly or indirectly, mediated pollinators, altered fitness. height was correlated concentration, alone (in absence pollinators) did affect reproduction. Bumble bees visited grown Exceeding Threshold less for shorter time compared Below sunflowers, honey sweat showed similar behavior across treatment levels. Sunflower set positively total visits, soil had marginally lower those soil. Our results suggest at levels plant-pollinator are affected consequences

ABSTRACT Pollinators are exposed to metals while foraging in the landscape and accumulate detectable concentrations of trace within their bodies, although major exposure routes remain unclear. As nectar is main source food for pollinators, we analyzed metal content floral rewards identify if contained may serve as an oral route. Nectar from flowering plant species growing vacant lots city Cleveland, OH, USA was extracted using a centrifuge tested arsenic, cadmium, chromium, lead ICP‐MS. We collected volunteer flower that common pollinator forage plants. varied by species, but not location. arsenic ranged 0 8.44 μg/L, cadmium 32.99 chromium 45.69 135.31 μg/L.

Abstract Infectious and parasitic agents (IPAs) their associated diseases are major environmental stressors that jeopardize bee health, both alone in interaction with other stressors. Their impact on pollinator communities can be assessed by studying multiple sentinel species. Here, we analysed the field exposure of three managed species ( Apis mellifera , Bombus terrestris Osmia bicornis ) to 11 IPAs (six RNA viruses, two bacteria, microsporidia). The bees were deployed at 128 sites eight European countries adjacent either oilseed rape fields or apple orchards during crop bloom. Adult each sampled before placement after detected quantified using a harmonised, high-throughput semi-automatized qPCR workflow. We describe differences among IPA profiles (richness, diversity, detection frequencies, loads change upon exposure, risk), no clear patterns related country focal crop. Our results suggest most frequent adult more appropriate for assessing bees’ risk. also report positive correlations supporting potential transmission sentinels, suggesting careful consideration should taken when introducing pollinators ecologically sensitive environments.

Abstract Urbanisation is associated with air and soil pollution, particularly from heavy metals. One of the tissues most exposed to such pollutants midgut epithelium as insects may ingest these food. Bees are one important urban insects, providing ecosystem services pollination. However, best our knowledge, no studies have investigated possible histological alterations bees caused by urbanisation. We sampled workers ground-nesting, primitively eusocial bee Halictus scabiosae in a large metropolis (Milan), aim test if individuals areas characterised higher urbanisation consequently pollution levels—defined here greater proportion roads—exhibit tissue cellular epithelium. obtained semi-thin sections through techniques, then adopted semi-quantitative approach assess morphological damage.
