Abstract Microplastics (plastics <5 mm, including nanoplastics which are <0.1 μm) originate from the fragmentation of large plastic litter or direct environmental emission. Their potential impacts in terrestrial ecosystems remain largely unexplored despite numerous reported effects on marine organisms. Most plastics arriving oceans were produced, used, and often disposed land. Hence, it is within systems that microplastics might first interact with biota eliciting ecologically relevant...
Microplastics can affect biophysical properties of the soil. However, little is known about cascade events in fundamental levels terrestrial ecosystems, i.e., starting with changes soil abiotic and propagating across various components soil–plant interactions, including microbial communities plant traits. We investigated here effects six different microplastics (polyester fibers, polyamide beads, four fragment types: polyethylene, polyester terephthalate, polypropylene, polystyrene) on a...
Soils are essential components of terrestrial ecosystems that experience strong pollution pressure. Microplastic contamination soils is being increasingly documented, with potential consequences for soil biodiversity and function. Notwithstanding, data on effects such contaminants fundamental properties potentially impacting biota lacking. The present study explores the microplastics to disturb vital relationships between water, as well its structure microbial During a 5-weeks garden...

Abstract Sturgeons seem to be frozen in time. The archaic characteristics of this ancient fish lineage place it a key phylogenetic position at the base ~30,000 modern teleost species. Moreover, sturgeons are notoriously polyploid, providing unique opportunities investigate evolution polyploid genomes. We assembled high-quality chromosome-level reference genome for sterlet, Acipenser ruthenus . Our analysis revealed very low protein rate that is least as slow other deep branches vertebrate...

For decades, we have known that chemicals affect human and wildlife behavior. Moreover, due to recent technological computational advances, scientists are now increasingly aware a wide variety of contaminants other environmental stressors adversely organismal behavior subsequent ecological outcomes in terrestrial aquatic ecosystems. There is also groundswell concern regulatory ecotoxicology does not adequately consider behavior, primarily lack standardized toxicity methods. This has, turn,...
The potential for agricultural chemicals to cause endocrine disruption (ED) in humans and wildlife is an increasing concern; however, the effects of commonly used pesticides at environmentally relevant concentrations are largely unknown. Therefore, 12 (11 herbicides pentachlorophenol (PCP)) were tested their disrupting two vitro assays. A recombinant yeast screen was detect receptor mediated (anti-) estrogenic androgenic activity (concentration range: 0.01−1000 μM), cultured Xenopus oocytes...
Previous investigations have shown that bisphenol A (BPA) induces a superfeminization syndrome in the freshwater snail Marisa cornuarietis at concentrations as low 1 μg/L. Superfemales are characterized by formation of additional female organs, enlarged accessory sex glands, gross malformations pallial oviduct, and stimulation egg clutch production, resulting increased mortality. However, these studies were challenged on basis incomplete experimentation. Therefore, objective current approach...

Eighteen different sampling points selected along whole course River from its spring at Aswan to estuaries Rosetta Damietta. Higher mean value conductivity, alkalinity, chemical oxygen demand (COD), total organic carbon (TOC), ammonia (NH3), nitrate (NO3), solid (TS), sulphate (SO4), chloride (Cl), orthophosphate recorded water Damietta branches comparing other sites.

Abstract: Microplastics can have direct physical effects on organisms in freshwater systems, and are considered as vectors for absorbed environmental pollutants. It is still under discussion if microplastics relevant pollutant uptake into aquatic comparison to further pathways, e.g., via water or sediment particles. We analyzed how the presence of (polyamide particles, PA) modifies acute bisphenol A (BPA) zooplankton (Daphnia magna). Daphnids were exposed PA particles BPA alone, before...
Abstract The aquaponic principle is the coupling of animal aquaculture (e.g. fish) with plant production vegetables) for saving resources. At present, various definitions aquaponics exist, some bearing risk misinterpretation by dismissing original meaning or being contradictory. In addition, there no standard terminology aspects between subsystems. this study, we addressed both issues. (1) We developed new revised that are summarised by: Aquaponic farming comprises (which couples tank‐based...
