Landscape influences bat suppression of pine processionary moth: Implications f...

Bats provide important ecosystem services, particularly in agriculture, yet integrating bat management into conservation plans remains challenging. Some landscape features considerably influence bat presence, diversity, and ecosystem service provision. Understanding the relationship between landscape structure, composition, pest suppression, and ecosystem services is crucial. We modelled areas where bats most e...

Therapy approaches for children with SSD: current practice of SLTs working in P...

Speech Sound Disorders (SSD) are the most common communication difficulties among preschool children . Recently, SLTs' role in managing SSD has garnered significant attention, leading to the development of various therapeutic approaches, from traditional articulation therapy to contemporary phonological and motor-based interventions. The choice of approach depends on the child's specific needs, disorder severit...

Impact of environmental caffeine contamination in zebrafish: ecotoxicological a...

Background: Caffeine (CAF) is considered a suitable indicator of anthropogenic contamination of aquatic environments, and several pharmacological and biological effects have been observed in target and non-target organisms [1,2]. Objective: Assess the chronic effects of environmental concentrations of CAF in several biomarker responses in Danio rerio. Methods: After chronic exposure to CAF (0.16, 0.42, 1.09, 2....

The unknown acute toxicity of the antibiotic sulfamethoxazole

Background: Sulfamethoxazole (SMX) is one of the most used antibiotics in the last 50 years, applied to humans, veterinary medicines, and aquaculture purposes ​[1]​. Detected in different environmental matrices this antibiotic can pose a risk to aquatic ecosystems and contribute to the spread of antimicrobial resistance ​[2,3]​. In addition, SMX has already been included in the 3rd Priority Substances Watch Lis...

Bioinsecticide SPINTOR®: detrimental effects on earthworms Eisenia fetida at di...

Background: The increasing interest in sustainable agricultural practices led to the use of biopesticides instead of synthetic ones [1]. SPINTOR® (SPI) is a commercialized bioinsecticide that employs spinosad as its active ingredient, a natural by-product obtained from the Saccharopolyspora spinosa fermentation [2]. Although effective in controlling several pests, SPI also can present inadvertent effects on non...

Acute toxicity screening of 4-chloroaniline in freshwater standard species

Background: Aromatic amines are commonly used in the production of pigments, dyes, pharmaceuticals, pesticides, and laboratory chemicals​ [1]​. Due to inappropriate discard and the ineffectiveness of wastewater treatment plants in removing these compounds, they are frequently detected in aquatic ecosystems​ [2]​, leading to 4-chloroaniline being considered a candidate for the 4th Watch List under the Water Fram...

Assessment of soil physicochemical characteristics and As, Cu, Pb and Zn contam...

This study aimed to evaluate soil physicochemical characteristics (pH, electrical conductivity, organic matter, total N, and extractable P and K), and potentially toxic elements (As, Cu, Pb, and Zn), in non-active mines located in the Portuguese sector of the Iberian Pyrite Belt (IPB). A total of 70 sampling sites were surveyed at Aljustrel and Lousal, in areas already rehabilitated, and at São Domingos, where ...

Potentially toxic elements’ contamination of soils affected by mining activitie...

Both sectors of the Iberian Pyrite Belt, Portuguese and Spanish, have been exploited since ancient times, but more intensively during and after the second half of the 19th century. Large volumes of polymetallic sulfide ore were extracted in open pits or in underground works, processed without environmental concerns, and the generated waste rocks and tailings were simply deposited in the area. Many of these mini...
