Summary: This study examined the consequences of delayed breeding in Magellanic penguins at Punta Tombo in Argentina using 34 years of data. The research found that the delayed onset of breeding had significant impacts on chick growth and fledgling condition, highlighting the importance of studying phenological shifts across multiple life events to understand their effects on organismal fitness.

Summary: Variations in group sizes are common in colonially breeding species like seabirds, with factors like nesting habitat quality influencing reproductive success. This study found that subcolony habitat characteristics significantly affect reproductive success, with smaller colonies showing more variability and being more impacted by interactions with nest predators.

Summary: This study documents an unprecedented heat-related mortality event of Magellanic Penguins in Argentina, caused by extreme high temperatures in a single day. The research found that both adult penguins and chicks died, potentially due to dehydration and lack of food. The mortality rates of adult penguins were unevenly distributed across the breeding colony, indicating the importance of microclimates and beach access to penguin survival.

Summary: The full flowering of cherry trees in Kyoto occurred on March 26, 2021, the earliest date in over 1200 years. This early shift in flowering season is a consequence of Kyoto's warming climate, which may have serious implications for the local economy. A study combining risk-based attribution methodology and a phenological model reveals that human activity, particularly urban warming, significantly contributes to the shift in flowering dates. By the end of the century, the early shift is projected to increase further, making extremely early flowering more common occurrences.

Summary: Drastic climate change poses a threat to penguins' ecological security. Previous studies have suggested that penguins disappeared from the Scott Coast around 2000 years ago due to either cooling or warming. However, recent findings show that penguin colonies were not abandoned on Dunlop Island around 2000 years ago, and there was a permanent snow/ice cover around 1700 years ago, indicating a Neoglacial cooling period. The abandonment of penguin colonies on the Scott Coast was likely caused by increased coastal sea ice and/or snow/ice accumulation during this cooling period.

Summary: Avian malaria, caused by infection with Plasmodium protozoa, is transmitted by mosquitoes and is particularly harmful to captive penguins. It often leads to acute death. Wild penguins can also be infected, but the significance of these infections is unclear. Global warming may increase the threat of avian malaria to captive penguin conservation. Current diagnostic methods rely on microscopy and molecular testing, but are not always able to identify the causative species.

Summary: This study examined the impacts of the Millennium Drought on the population decline of the little penguin in Australia. The findings showed negative associations between penguin numbers and sea surface temperatures as well as river outflow, while annual penguin numbers were positively associated with southern garfish numbers and negatively associated with annual chlorophyll-a concentrations. These findings highlight the need for further research on the effects of hydrological droughts on seabird populations and improved river management.

Summary: Climate change cannot be mitigated by individual actions alone. Structural change is necessary, and people in wealthy countries are more likely to support structural climate policies than individual behavior change policies. Perceiving wealthy countries to have a moral obligation to contribute to global solutions may mediate this preference. These findings suggest that there is strong public support for wealthy countries to lead structural transformations in order to address climate change.

Summary: This study focused on the substantial threat that humid-heat poses to human health, finding that since 1979, the frequency of dry- and humid-heat extremes has increased over most land regions globally, with humid-heat extremes disproportionately increasing in populated regions compared to the global average growth rate.

Summary: The study assessed the potential effects of climate change on Eudyptes penguins and found that it may lead to a reduction in their preferred habitat. The results showed that the impact would be less severe under a less severe climate change scenario. The penguins may also experience a poleward redistribution and the effects would vary across different regions and species.

Summary: This paper introduces a new method for quantifying changes in sand surface elevation in relation to plant growth characteristics, which is low-cost, lightweight, and the platform is made of steel and Perspex, suitable for effective field experiments in Australia. The results of the experiment show that plant growth has a significant impact on sand deposition, assisting in planning dune morphology and aiding in dune recovery after erosion.

Summary: The study found that reproductive strategies of little penguins are influenced by marine productivity and individual age. In autumn, older and more experienced penguins showed mating-like behavior, indicating an earlier attempt to breed. This supports the prediction of life-history theory that increasing investment in reproduction with age is to maximize lifetime fitness.

Summary: This study found that storm events affected the foraging efficiency of little penguins, with increased foraging trip duration, lower prey encounter rate, and reduced body mass gain during the storm. The adverse effects on foraging efficiency continued after the storm, indicating a prolonged impact on prey availability. When occurring at critical breeding stages, these events may affect breeding success.

Summary: Climate change and human activities have profound effects on marine ecosystem productivity, particularly impacting seabird breeding success, with stronger effects on fish-eating species in the northern hemisphere; hence, ocean management at hemispheric scales and targeted recovery plans are necessary. In the southern hemisphere, lower changes in seabird productivity provide opportunities for strategic management approaches like establishing large marine protected areas to sustain food webs and predator productivity.

Summary: Over the past decades, changes in vegetation cover and dune mobility in the Woolamai dune fields on the southeast coast of Australia have undergone a transition from bare sand to fully stabilized state, with distinct early expansion, rapid growth, and recent quasi-equilibrium phases. Vegetation growth is influenced by multiple factors such as topography, climate, and human activities, with stability or mobility of the dune system depending on these interactions.

Summary: Reproductive performance in little penguins typically improves with age, peaks at around 8 years old, plateauing before declining after age 16. Within-individual changes played a dominant role in age-dependent breeding success, with both selection and within-individual processes affecting breeding performance.

Summary: Foraging behavior is crucial to breeding success for marine predators, such as seabirds like the endangered Yellow-eyed penguins. A detailed study of the subantarctic population, distinct from the declining northern population, revealed greater foraging plasticity and a preference for pelagic foraging. Variations in foraging conditions due to local bathymetry, environmental conditions, and individual preference could impact future breeding success in the subantarctic.
