Summary: The stomach contents of Short-tailed shearwater provide early evidence of oceanic plastic pollution and comparative data for the Pacific Ocean. A mortality event in 2019 contributed additional data for spatiotemporal comparisons. Plastic loads and particle dimensions in the North and South Pacific were similar, indicating that plastic retention in shearwaters is influenced by factors such as body size, gastrointestinal structure, and species' preferences rather than the availability of oceanic plastic.

Summary: The presence of humans at night has an impact on the behavior and numbers of Little Penguins on Granite Island in South Australia. The use of white light and the presence of dogs lead to later returns and more vocalizations by the penguins. Conversely, concerts have less of an effect. The COVID-19 pandemic has also significantly affected human activities and their impact on wildlife.

Summary: This study provides the first description of the ultrastructure of the cornea in two different-sized Little Penguins, revealing a range of functional adaptations that reflect the amphibious lifestyle of this seabird. The corneas show unique features such as microprojections, varying epithelial cell densities, and a distinct attachment to the basement membrane. Overall, the corneal components in Little Penguins display specific adaptations to their environment and lifestyle.

Summary: This study identified and compared the attitudes of visitors toward little penguins at two Australian zoos. Results showed that most participants had positive attitudes toward little penguins, penguin welfare, the enclosure, and visitor experience. However, whether these attitudes influenced visitor behavior toward the penguins remains unclear.

Summary: Investigating foraging decisions helps understand how animals efficiently obtain and use food. This study used animal-borne cameras to examine predator-prey interactions in little penguins, discovering previously undocumented prey consumption and strategies. The study found that chase and handling times varied with prey type and that penguins consumed less profitable prey, suggesting a trade-off between minimizing energetic costs and increasing capture rates. These results demonstrate the importance of animal-borne video data loggers in studying foraging adaptations of marine predators.

Summary: Routine post mortems of deceased penguins from Penguin Island, Western Australia, found a temporal cluster of cases with characteristic gross and microscopic changes. Protozoan parasites were identified and molecular investigations gave inconsistent results. Toxoplasma gondii was confirmed as the cause of mortalities, with some cases also showing concurrent Haemoproteus infection.

Summary: Quantifying prey characteristics is important for understanding predator foraging behavior. In this study, animal-borne video data loggers were used to investigate the foraging behavior of little penguins in southeastern Australia. The results suggest that prey type and patch density influence foraging behavior, while breeding season constraints impact foraging trip distance and duration.

Summary: The study found that the breeding performance of short-tailed shearwaters is influenced by both large-scale climate indices and local environmental conditions. There is variability in adult body mass and breeding participation among different colonies, with these factors being affected by climate conditions in the previous year. Breeding success, on the other hand, is influenced by climate conditions in the preceding three to four months and local weather conditions during breeding.

Summary: This study found the presence of class 1 integrons in the little penguin, supporting the use of marine birds as sentinels of antimicrobial resistance in marine environments. There was a significant difference in the prevalence of class 1 integrons between wild and captive groups, and these genes were not detected in clinically relevant bacterial species Klebsiella pneumoniae or Escherichia coli isolated from penguin feces.

Summary: The study found that the increase in penguins avoiding the visitor viewing pier when the exhibit was open to visitors may be due to the fear-provoking nature of close contact with visitors, especially when visitors loom over the penguins.

Summary: This study reveals that suitable breeding habitat for little penguins along the greater Kaikoura coastline is limited and lacks data. The use of a Protected Species Detection Dog conducted the first comprehensive survey, locating little penguins in only 0.7% of the coastal stretch. The study highlights the importance of the breeding colony in South Bay and recommends the protection of existing habitat.

Summary: In this study, the range of Strouhal numbers for Little penguins was estimated using field data, and the relationship between this range and the shape and depth of dives was investigated to understand their behavioral adaptations for underwater swimming. The reliability of the Strouhal number estimate was evaluated by calculating the Reynolds and Swimming numbers, confirming that penguins employ efficient propulsion mechanisms.

Summary: The study used tracking devices to investigate the year-round distribution of Campbell albatross, finding their utilization of cool waters during the breeding season and movement to warmer waters during the non-breeding period. One individual made a circumnavigation of the southern oceans after a failed breeding attempt in 2009. The overlap with fishing activity fluctuated throughout the study period.

Summary: The legacy of deliberate and accidental introductions of invasive alien species to Australia has resulted in significant economic costs, with at least $298.58 billion (2017 value) spent or lost since the 1960s. Costs have been increasing at an average rate of 1.8-6.3 times per decade, with plants being the primary contributors to the total costs. Different regions in Australia face major costs from different species, but most losses are caused by one to three species.
