Summary: Migration timing in animals can evolve to match seasonal changes in abiotic conditions and resource pulses, but shifts due to climate change may disrupt this synchronization. Climate change can influence migration timing through various pathways, while factors unrelated to climate like anthropogenic modifications, demographic effects, and fisheries can also impact phenology. This makes it challenging to determine the causal basis of observed patterns, requiring rigorous testing of mechanistic hypotheses and systematic ruling out of alternative causes. Salmon exemplify the complexities of migration timing changes, from climate shifts to anthropogenic influences.

Summary: Major seasonal quasi-stationary fronts on shelves have an important role in regulating the spatiotemporal variations in the phytoplankton community. This study examines the climatological relationship between the Shandong coastal front (SCF) and spring phytoplankton bloom (SPB) in the Yellow Sea. The results show that the intensity and structure of the frontal system and the turbulence are important prerequisites for initiating and determining the magnitude of SPB.

Summary: This study aimed to explore how the social environment influences the spring migration traits of male yellow-rumped warblers. The results showed that sex ratio did not affect body mass or molt progression, but males in the male-biased treatment exhibited significantly less locomotor movement. These findings suggest that the social environment can impact the behavior of songbirds, but do not support the hypothesis that a male-biased sex ratio accelerates migration.

Summary: Understanding movement patterns of anadromous fishes is crucial for their conservation and habitat preservation. This study focused on green sturgeon in the Sacramento River system and revealed distinct migration patterns, with a unimodal in-migration during spring and a bimodal distribution of out-migration timing. River discharge, rather than water temperature, seemed to cue the timing of migration. The findings highlight the importance of accurately describing migration periods and encourage the use of biotelemetry in studying different populations and species.

Summary: This study evaluated three thermal time models and two irrigation methods for spring frost protection of American cranberry. The WI(30-5) thermal time model provided the most accurate estimates of bud phenology, and although cycling irrigation resulted in slightly higher bud damage, it did not reduce fruit yield and offered water savings of up to 35% compared to conventional frost irrigation.

Summary: This study used a large amount of bird banding data to investigate the changes in spring and fall migratory phenology for different sexes and age classes of bird species. The results showed that adult males arrived first in spring, while immature females arrived last, consistent with protandry. In the fall, there was little difference between sexes, but adults tended to depart earlier than juveniles. Additionally, the study found that male birds were advancing their phenology at a faster rate compared to females, causing the gap between male and female arrival times to widen over time.

Summary: Plasticity in breeding dates can affect population vulnerability to climate change via phenological mismatch. Early-nesting duck species showed stronger plasticity in response to spring temperature, while late-nesting species exhibited annual variation in clutch initiation dates. Some individuals within species showed varying levels of plasticity, and certain species had interannual repeatability of CID. Fitness consequences of CID plasticity in response to spring phenology require further investigation.

Summary: Tree crowns experience strong vertical microclimatic gradients, particularly in light availability. Little is known about whether these gradients cause within-crown variation in leaf phenology and whether such variations represent different light-use strategies of sun-and shade leaves. We measured the annual leaf phenology in the upper and lower crowns of mature trees from different species and found that microclimatic canopy gradients are strongest during summer and may drive phenological gradients in autumn.

Summary: Life history theory suggests that organisms should time their reproduction to maximize fitness. This study found that differences in breeding time among individuals in a perch population were associated with changes in hatching success and reproductive allocation strategies, as well as variation in offspring performance linked to temperature. These time-dependent adaptive differences within the population could influence the population's ability to cope with environmental challenges, such as global warming and exploitation.

Summary: Emergent properties of ecosystems are community attributes that arise from interactions among populations, species, or assemblages, and climate change is altering these properties in aquatic ecosystems, which could lead to species extinctions and reductions in ecosystem services. Progress has been made in understanding how climate change affects emergent properties of aquatic ecosystems, but responses are complex and uncertain.

Summary: The timing of life history events in many plants and animals is affected by seasonal environmental fluctuations, with anadromous fishes being particularly sensitive to climate change. Water temperature was found to be the most consistent predictor of river herring migration patterns, while effects of streamflow and lunar phase varied. Vulnerabilities to climate change were identified in more northerly runs due to later migration in warmer water and a narrower temporal window.

Summary: Resource selection functions (RSFs) are widely used in terrestrial ecology but have not been extensively applied in marine systems. By combining RSFs with machine learning algorithms in acoustic telemetry data, new insights can be gained to prioritize habitat conservation in marine environments. This approach can be valuable for marine ecologists and resource managers in guiding conservation efforts and achieving high prediction accuracy.

Summary: Species' response to rapid climate change can be measured through shifts in timing of recurring biological events. In this study, the authors used data from a 20+ year marine mammal observation program to examine the phenological shifts and trends in habitat use for large whales in Cape Cod Bay. They found that the date of peak habitat use for right and humpback whales had shifted earlier by approximately 18 and 19 days respectively. The study also revealed that right whales exhibited a stronger response to seasonal temperature changes compared to fin and humpback whales.

Summary: In recent years, there has been a rapid increase in the number and diversity of phenological studies. These studies, including innovative experiments, field research, citizen science projects, and analysis of historical data, are providing valuable insights into ecological and evolutionary responses to the environment, especially climate change. However, analyzing and interpreting phenological data can be challenging due to hidden peculiarities in the data sets. This paper presents ten best practices for designing, evaluating, and analyzing plant and animal phenological studies, aiming to help researchers, particularly those new to the field, make the most of available data and approaches to advance our understanding of phenology and its ecological implications.

Summary: Recent reports of insect declines, attributed to anthropogenic land use intensification and climate change, have raised concerns among scientists and the public. This study provides evidence of long-term continuous declines in insect biomass and abundance in a protected subalpine meadow, which is embedded in an undisturbed natural landscape. The declines were correlated with changes in climate, specifically with less summer precipitation and winter snowfall, as well as warmer temperatures, suggesting that even relatively undisturbed habitats may not be immune to further insect declines.
