Summary: This study investigates the dormancy depth and cold hardiness of woody temperate plant species during winter and their effects on frost risk. The maximum dormancy depth occurs between early October and early December, while cold hardiness peaks in mid-winter. Over the past 70 years, budburst dates have advanced, and dormancy depth in early spring has increased due to reduced chilling accumulation. However, cold hardiness has decreased due to weakened acclimation and accelerated deacclimation. Frost risk before and after budburst remains unchanged due to the decreased occurrence and severity of low-temperature events and earlier late spring frosts.

Summary: Climate change can lead to phenological changes in populations, impacting community interactions and evolutionary processes. In this study, we investigated the response of two sympatric populations of Rhagoletis pomonella flies and their parasitoid wasps to climate warming. We found that warmer temperatures caused earlier development in both fly populations, but had a significant and maladaptive effect on pre-winter development in apple flies. Parasitoid phenology showed less sensitivity to warming, potentially leading to ecological asynchrony. Our findings suggest that climate-induced shifts in fly phenology may reduce temporal isolation and limit ongoing divergence in specialist communities.

Summary: Budbreak, one of the most studied phenological phases in perennial plants, is challenging to predict due to poor understanding of dormancy. The accumulation of chilling and heat units are used to model budbreak, but the negative correlation between them suggests that more chilling leads to less forcing required for budbreak. Furthermore, variation in chilling requirements between temperate plant species affects dormancy completion and proper budbreak. This study highlights the importance of considering cold hardiness to accurately predict budbreak and suggests a new framework for studying dormancy based on cold hardiness dynamics.

Summary: Budbreak, an important phenological phase in perennial plants, is influenced by dormancy which is poorly understood. The exposure to temperature, specifically chilling and forcing, plays a role in modeling budbreak. Cold hardiness is found to be a crucial aspect of dormancy and should be considered in studying dormancy and predicting budbreak. The rates of cold hardiness loss vary among species, leading to different times to budbreak, and are influenced by the accumulation of chill. Inherent differences in deacclimation rates between species can be standardized using a deacclimation potential measurement. This finding contradicts previous estimations based on budbreak assays and emphasizes the need for understanding cold hardiness dynamics in comparing dormancy control.

Summary: This study investigates the phenotypic and genomic changes of the Asian tiger mosquito, Aedes albopictus, in its native range and finds evidence of thermal adaptation and three evolutionary lineages. The study also identifies temperature-associated differentiation in certain genes, suggesting the role of directional selection. Furthermore, the study reveals that the mosquitoes store more energy in colder climates and that non-diapausing eggs from temperate populations have higher cold tolerance.

Summary: Low temperatures in winter can have a negative impact on the survival of organisms, particularly ectotherms. This study investigates the variation in overwintering strategies among groups of closely interacting parasitoid species. The researchers found that different species of endoparasitoid wasps exhibited similar diapause phenotypes as their host insect, the apple maggot fly. The study also reveals a high level of cold tolerance and consistency in survival rates among the three wasp species.

Summary: Climate change has caused phenological shifts in different species and trophic levels, with a recent slowdown in the rate of advance due to a decrease in late spring temperatures. It is projected that prey phenology will advance faster than predator phenology in the coming decades, intensifying phenological mismatches.

Summary: Species with different life histories and communities tend to shift their phenology in response to climate warming, leading to increased phenological overlap and potential impacts on species interactions such as resource competition. Shifts in abundance distributions are not strongly influenced by species' seasonal timing or elevations, but phenological overlap increases in warmer years as species adjust their seasonal timing. Overall, grasshopper abundance is relatively robust to climate changes, but increased phenological overlap may decrease abundance by strengthening species interactions.

Summary: Seasonal phenology forecasts are in high demand by winegrowers and viticulturists. This study assesses the performance of seasonal forecasts in predicting flowering and veraison stages of two representative varieties in Portugal. The study finds that forecast performance is influenced by initialization timings, regions, and predicting subjects. Improved forecast performance is observed with delayed initialization and only April 1st initialized forecasts outperform climatology in predicting phenology terciles. The study highlights the importance of climate variability in forecast performance and suggests methodological innovations and practical applications for reliable phenology forecasts.

Summary: The electrolyte leakage method is widely used in assessing plant tissue cold hardiness, with standardizing raw data proving to be crucial for reliable estimation of cold hardiness at the species level and across diverse systems. The use of liquid nitrogen control enhances the consistency and realism of the method, especially for very cold hardy samples. Data from studies using this control method can still be compared to previously published data when standardized using the best-performing approach.

Summary: The sex pheromone system is crucial for attracting conspecific mates, and in the European corn borer moth, variations in pheromone blend and male preference are controlled by pgFAR and bab genes, respectively. The linkage disequilibrium between bab and pgFAR genes validates their interaction in contributing to assortative mating. Lack of physical linkage does not constrain the coevolutionary divergence of female pheromone production and male behavioral response genes.

Summary: Understanding the molecular basis of repeated evolution improves our ability to predict evolution across the tree of life. High-throughput sequencing has enabled comparative genome scans to examine the repeatability of genetic changes driving phenotypic evolution. Asian corn borer and European corn borer show repeatable phenological adaptation to different climates, and circadian rhythm genes play a role in this repeated adaptation. Independent mutational paths and adaptive introgression may contribute to the repeated phenological evolution.

Summary: The study used 27 years of citizen science monitoring data to quantify trends in butterfly phenology and relative abundance, finding that elongated activity periods within a year may be a key factor in increasing abundance. Some species appear to be adding a late-season generation, while others appear to be adding a spring generation, indicating a possible shift from vagrant to resident.
