Article Synopsis
- Extreme climatic events (ECEs) like marine heatwaves pose serious threats to biodiversity, highlighting the need for understanding ecological responses to these recurring events.
- Researchers used a "multiple events" approach to study the effects of recurrent ECEs on the temperate coral Paramuricea clavata, assessing factors like environmental, genetic, and phenotypic influences over three years.
- Findings indicated that environmental impacts were the primary drivers of coral responses, with limited evidence of genetic adaptability, suggesting that P. clavata populations face significant challenges due to ongoing heat stress and may struggle to recover.
The presence of pharmaceuticals in agricultural soils, like amoxicillin (AMX) and ciprofloxacin (CIP), poses a significant environmental challenge with potential implications for ecosystems and human well-being. This study explores the simultaneous adsorption of AMX and CIP on crop soils and bio-adsorbents, focusing on competitive adsorption dynamics. Tests were conducted with varying pharmaceutical concentrations in six soils and three bio-adsorbents.

- - The study focuses on the Magellan Subantarctic ecoregion, highlighting how accelerated glacial ice melt creates unique environmental conditions that impact marine biodiversity and epiphytic microalgal communities.
- - Researchers analyzed epiphytic microalgal assemblages on various benthic macroalgae across sites with different glacial and oceanic influences, documenting 67 genera and noting significant variations in diversity based on environmental factors.
- - Findings revealed that environmental gradients, particularly from glacial influence, are the primary drivers of epiphytic variation, with some potentially harmful microalgae identified, contributing to a better understanding of this complex ecosystem in light of climate change.
The anticoccidial monensin (MON) is a high-concern emerging pollutant. This research focused on six low-cost bio-adsorbents (alfa, cactus, and palm fibers, and acacia, eucalyptus, and zean oak barks), assessing their potential for MON removal. Batch adsorption/desorption tests were carried out, and the results were fitted to the Freundlich, Langmuir, Linear, Sips, and Temkin models.

Among these emerging pollutants, ionophore anticoccidials are of special concern due to their potential ecological impact, persistence in the environment, and role in promoting antimicrobial resistance. To investigate the adsorption/desorption of the ionophore antibiotic salinomycin (SAL) on/from raw and modified clay adsorbents, batch-type experiments were performed using 0.
