Microplastics (MPs) are ubiquitous pollutants of increasing concern in aquatic systems. However, little is still known about the impacts of weathered MPs on plankton at the community level after long-term exposure. In this study, we investigated the effects of weathered MPs on the structure and dynamics of a Baltic Sea planktonic community during ca.

Hybridization of distinct populations or species is an important evolutionary driving force. For invasive species, hybridization can enhance their competitive advantage as a source of adaptive novelty by introgression of selectively favored alleles. Using single-nucleotide polymorphism (SNP) microarrays we assess genetic diversity and population structure in the invasive ctenophore in native habitats.

Article Synopsis
- Plankton imaging systems with automated classification have enhanced the study of aquatic ecosystems by enabling detailed tracking of plankton populations.
- These systems capture high-resolution imaging data, offering insights not only into species abundance but also into functional traits of individual plankton.
- The text suggests using machine learning and computer vision techniques to analyze this imaging data, proposing that these methods could be applied to other organisms in both aquatic and terrestrial environments.

Invasion rates have increased in the past 100 y irrespective of international conventions. What characterizes a successful invasion event? And how does genetic diversity translate into invasion success? Employing a whole-genome perspective using one of the most successful marine invasive species world-wide as a model, we resolve temporal invasion dynamics during independent invasion events in Eurasia. We reveal complex regionally independent invasion histories including cases of recurrent translocations, time-limited translocations, and stepping-stone range expansions with severe bottlenecks within the same species.

To test this hypothesis, we used juvenile common-garden reared carp () within a narrow size range to investigate the mechanistic basis of behavioral selection caused by angling. We focused on one key personality trait (i.
