Summary: Network theory provides innovative tools to explore complex ecological mechanisms regulating species associations and interactions. However, the application of network approaches is unevenly distributed across different study systems, with aquatic macrophyte-animal associations in coastal environments being largely neglected. Network analysis has the potential to broaden our understanding of coastal ecosystems and their response to anthropogenic disturbance and environmental change.

Summary: We conducted a study on sources, abundance, and risk of microplastics (MPs) in water, sediments, and biota around Antarctica. The concentration of MPs in the Southern Ocean ranged from 0 to 0.56 items/m3 in surface water and 0-1.96 items/m3 in sub-surface water. The distribution of fibers, fragments, and film varied among the different matrices, with fibers being most abundant in sediments, and fragments being most abundant in water. The pollution load index (PLI), polymer hazard index (PHI), and potential ecological risk index (PERI) were used to assess the degree of pollution and ecological risk, with overall low pollution load but high ecological risk observed in the study area.

Summary: This study compares thermal performance within and between species of seagrass and seaweed in the Mediterranean Sea. The results show significant differences in thermal performance between species, with optimal temperatures varying by over 10 degrees Celsius within the same location. Within-species differences are also important, with seagrass populations displaying larger thermal safety margins in extreme temperatures. The findings suggest that the thermal performance patterns of these marine communities are influenced by deep pre-Mediterranean evolutionary legacies.

Summary: Seagrasses have suffered significant losses globally due to human impacts and marine heat waves. The lack of information on seagrass mortality thermal thresholds hinders the assessment of seagrass loss risk in heat waves. Through synthesis of existing data, it was found that seagrass upper thermal limits increase with local annual temperature. By combining climate data and models, the study assessed the proximity of seagrass meadows to their thermal limits and the time required to reach these limits under different greenhouse gas emission scenarios. The study highlights the importance of implementing the goals under the Paris Agreement and taking actions to remove local anthropogenic stresses.
