Summary: This study used stable isotope ratios to investigate the moulting location and diet of Great and Sooty Shearwaters. The results showed that both species completed their moult in coastal Newfoundland, with some differences in moult advancement. The study also revealed divergent locations and diets during early moult, but convergence in diet when the feathers of both species were sampled in coastal North America. Protecting this moulting area is essential to minimize disturbance and threats to these species.

Summary: The study found that the prevalence of neoplastic tumors around the Great Lakes is at acceptable levels, but higher levels of preneoplastic lesions were found in several impacted locations. Additionally, weak to moderately strong relationships were observed between tumor occurrence and fish physical characteristics, which varied considerably among different locations.

Summary: This study investigated the occurrence and potential antimicrobial resistance of Salmonella spp., Escherichia coli, and Listeria monocytogenes in seal fecal samples. The results showed that seals may act as important sources and vectors for antimicrobial-resistant and pathogenic bacteria. Further characterization of these isolates would provide insights into the source and spread of antimicrobial resistance and virulence genes in free-living seal populations.

Summary: This study provides a baseline understanding of gastrointestinal parasite infections in free-living baleen whales, revealing three potentially zoonotic parasite species. The research highlights the need for further non-invasive studies to better understand and conserve vulnerable baleen whale populations.

Summary: The study identified new locations of monkey gobies in the waters of the Great Masurian Lakes system, where they were found to have small physical characteristics. The findings suggest that monkey gobies may rapidly spread to lakes in the northern basin of the system.
