Efforts to remediate and restore degraded ecosystems through Nature-based Solutions (NbS) have intensified during the United Nations Decade for Ecosystem Restoration (2021-2030). To evaluate the potential of seagrass transplantation for recovering historically contaminated areas, a mesocosm experiment was performed with the following objectives: 1) assess the suitability of the transplant method; 2) evaluate the tolerance of Zostera noltei to different concentrations of metal(loid)s in sediments; 3) clarify the tolerance mechanisms and measure oxidative stress levels and energy budget across different tissues and sampling times; and 4) investigate its potential as a Nature-based Solution. Results demonstrated that seagrass could tolerate various concentrations of metal(loid)s in sediments and activate mechanisms to reduce oxidative stress, without interfering with its growth and seasonal life cycle. The use of Zostera noltei as a NbS for remediating, restoring, and rehabilitating historically contaminated areas was validated and appears to be a promising approach.

Background: The small hive beetle (SHB; Aethina tumida) is a significant pest affecting honey bees and the global beekeeping industry. The harmful effects of chemical pesticides on bee health, non-target species and ecosystems highlight the need for sustainable SHB control methods. Soil applications of entomopathogenic nematodes (EPNs) targeting the soil-dwelling life stages (wandering larvae, pupae and emerging adults) of SHB present a promising biological control approach.

This study investigates the ecotoxicological effects of BDE-209, a persistent organic pollutant (POP), prevalent in Kuwait's coastal-industrial zones, on meiofaunal communities. A mesocosm experiment was conducted, exposing sediment-dwelling meiofaunal communities from sediments near Failaka Island (Kuwait) to gradient concentrations of BDE-209 (0.01-20 mg/kg) over a 4-week period.

Globally, freshwater ecosystems are threatened by multiple stressors, yet our knowledge of how they interact to affect food web structure remains scant. To address this knowledge gap, we conducted a large-scale mesocosm experiment to quantify the single and combined effects of three common anthropogenic stressors: warming, increased nutrient loading, and insecticide pollution, on the network structure of shallow lake food webs. We identified both antagonistic and synergistic interactive effects depending on whether the stressors affected negative or positive feedback loops, respectively.

The thermal sensitivity of task performance in ectothermic organisms may depend on how temperature affects mobility, cognitive ability, or their interaction. Furthermore, these processes may vary with experience or task difficulty. To test these predictions, we performed mesocosm experiments with common rudd (Scardinius erythrophthalmus) foraging for a high-density food reward (Artemia salina nauplii) across consecutive daily sessions under varying task difficulties (short, medium, and long distances to the reward, and presence or absence of experienced individuals) at two temperatures (16-26 °C).
