Ivermectin causes adverse effects on the metabolic rate and thermoregulatory capacity of Dung beetles

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: Feb. 26, 2025

Ivermectin (IVM), a commonly used endectocide in livestock, has been shown to produce adverse effects dung beetle ecology, physiology, reproduction, and even their ecosystem services. However, the ever-growing ecological importance of thermoregulation its associated metabolic demand beetles not received as much focus regarding this drug. Here, we evaluated experimentally caused by IVM rate Ateuchetus cicatricosus (Lucas, 1846), using standardized ecotoxicity test based on thermolimit respirometry combined with infrared thermography (TLR-IR). The total capacity excess heat regulation (iTR) caloric (MR) gave most sensitive responses ingestion. inhibition concentration at 50% (IC50), relevant toxicity threshold calculate that provokes response half way among obtained showed iTR was impacted 0.39 µg g–1, while MR compromised 0.24 g–1. Applying TLR-IR procedure only revealed how active thermoregulators is crucial for adaptation warm competitive environments, but also potential method be applied real-world scenarios like cattle-farming regions, where need assess direct impact endectocides vital update enhance guidelines these pharmaceuticals.

Trace Metals in Nectar of Important Urban Pollinator Forage Plants: A Direct Exposure Risk to Pollinators and Nectar‐Feeding Animals in Cities

Ecology and Evolution, Journal Year: 2025, Volume and Issue: 15(4)

Published: April 1, 2025

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. The presence these soil contaminants indicates uptake concentration resources likely route pollinators nectar‐feeding animals.

From molecules to organisms: a multi-level approach shows negative effects of trace elements from sewage sludge used as soil improver on honeybees

Journal of Hazardous Materials, Journal Year: 2024, Volume and Issue: 478, P. 135497 - 135497

Published: Aug. 13, 2024

The use of sewage sludge as a soil improver has been promoted in agroecosystems. However, sludges can contain toxic trace elements because suboptimal wastewater treatment. Nonetheless, field studies investigating the negative effects these practices on pollinators are lacking. We collected honeybees from an area where is widespread, and one it precluded. Trace soils bees were quantified. Cadmium, chromium, lead, mercury, nickel investigated they least correlated to each other known be toxic. Their levels related oxidative stress energy biomarkers, midgut epithelial health, body size wing asymmetry honeybees. found increased carbohydrate content sites with higher cadmium levels, histological damage epithelium area, presence dark spherites highest lead levels. Finally, we that smaller, fluctuating increasing mercury. To best our knowledge, this first comprehensive study concentration potentially deriving amendment practices.

Abstract Background The common Eastern bumble bee Bombus impatiens is native to North America and the main commercially reared pollinator in Americas. There has been extensive research on this species related its social biology, applied pollination, genetics. genome of was previously sequenced using short-read technology, but recent technological advances provide an opportunity for substantial improvements. This agricultural urban environments, heavy metal contaminants produced by industrial processes can negatively impact it. To begin identify possible mechanisms underlying responses these toxins, we used RNA-sequencing examine how exposure a cocktail four metals at field-realistic levels from areas affected B. worker gene expression.
