The authors compared ecological and social dimensions of recreational angling and spearfishing targeting the invasive bluefish (Pomatomus saltatrix) in Italy using digital videos and their associated data. The study showcases the value of exploring social media to understand the ecological and human dimensions of marine recreational fisheries in relation to distributional range shifts of species.

The theoretical study evaluated the microbial dynamics of particle-associated vs free-living bacteria. Bacterial generalists have the ability to utilize both habitats and increase stability and energy transport through the 'microbial loop'. Adaptive response strategies of bacteria are important to assess the consequences of increasing particle loads, e.g., sediment and microplastics.

The authors studied the role of host genetics in host-associated microbiome community structure. Gut and body microbiome composition still varied between Daphnia host genotypes, even though these Daphnia were kept under identical lab conditions for five years. This highlights the importance of host genetic component in microbiome structure.
