Summary: A study found that although the potential growing season length increases due to climate warming, the growth period in alpine grasslands does not extend even with a prolonged growing season, but instead promotes the growth of species with less strict phenology.

Summary: The timing of flowering in plants is highly sensitive to climate change. Warming advanced the first and last flowering times differently and resulted in the entire flowering period occurring earlier in the growing season. Early-flowering species were more sensitive to warming, reducing the synchrony among species and extending the community-level flowering season. Precipitation and its interactions with warming had no significant effects on flowering phenology.

Summary: This study investigated the isolation factors responsible for the frequency and asymmetry of hybrid T. miyabeanum formation in a sympatric population of T. apetalon and T. tschonoskii. The results showed that premating isolation barriers, especially flowering phenology and breeding system differences, had a greater impact on hybrid formation. Hybrids with T. apetalon as the maternal parent had lower viability and did not reach the flowering stage. The asymmetry of the isolating barriers may promote T. tschonoskii as the maternal parent of T. miyabeanum.

Summary: This study investigates the function of the LpFTLs gene in hybrid chrysanthemum and Leucanthemum paludosum, and finds that the flowering phenotype of hybrid offspring in spring is possibly related to the expression of the LpFTLs gene. The ectopic expression of the LpFTLs gene in Arabidopsis thaliana resulted in earlier flowering, indicating its role in flowering time in L. paludosum. The compound expression of FTLs in the hybridization of C. morifolium x L. paludosum leads to significant hybrid vigor in the offspring, but the balance of vegetative and reproductive growth affects continuous flowering.

Summary: The flowering phenology and flower-visiting insects of an alpine site in central Taiwan were investigated. The results showed that bees, flies, and other insects were the main flower visitors, with bees being more associated with seasonal patterns of flowering. The abundance of bumble bees consistently increased as the season progressed, reflecting colony development.

Summary: This study aimed to investigate the mating systems and pollination success of alpine plants. The results showed that most alpine plants have a common mating system of outcrossing, and the fruit-set success varied seasonally in response to pollinator activity. Bumble bees are the main pollinators for alpine plants, and the success of pollination differed among different pollinator types. The flowering phenology of alpine plants is regulated by snowmelt patterns, and the pollination success also varied among local populations in different snowmelt habitats.

Summary: This study investigated the flowering phenology adjustment and flower longevity compensation hypotheses in an alpine species in the Andes of central Chile. The results suggest that while high-elevation populations may exhibit differences in flowering timing, flower longevity is not extended at higher elevations to compensate for the decrease in pollination rates.

Summary: This study proposes a novel method to optimize the timing of survey windows by maximizing the detectable species pool. A proof of concept is presented using 20 years of entomological records in Switzerland. The study offers a new practical tool for adaptive entomological monitoring under climate change.

Summary: This study reports how a new phenotype of hybrids between two Imperata cylindrica ecotypes contributes to rapid reproductive isolation from their parents and affects hybrid fitness. The hybrid populations consist of only F-1 individuals, without advanced generation hybrids. The flowering phenology of the F-1 plants is delayed, preventing backcrossing, and changing seed dispersal time. This study highlights the importance of hybrid traits in driving rapid reproductive isolation.

Summary: This study investigates the phenological changes of plants in the widespread sagebrush ecosystem of the Western United States. The research finds that the flowering time of early spring and mid-summer flowers has significantly shifted earlier. These changes can lead to asynchrony or new synchrony among important wildlife species, highlighting the importance of maintaining a diverse portfolio of native plants in conservation efforts.

Summary: In Croatia, a selection and clonal seed orchard of wild cherry trees were established, showing diversity in reproductive traits among the clones. Some clones had better fruit setting, but showed weak correlation with other characteristics.

Summary: Global warming accelerates flowering in alpine plants, potentially decreasing fruit production due to lower pollination and increased frost damage. The effects of phenological variation on fruit-set success vary by location, with the greatest impact early in the growing season.

Summary: The study found that male-biased sex allocation was common in early-flowering populations, while the number of male and perfect flowers did not correlate with seed predation rate. Fruit-set success was positively correlated with the number of perfect flowers, indicating a significant impact of perfect flowers on fruit set.

Summary: This study evaluated the sexual systems of different populations of Daphne jezoensis in Japan, finding that the gynodioecy composed of females and hermaphrodites with low seed fertility is a relatively stable sexual system. The research suggests that occasional seed production in hermaphrodites does not necessarily indicate a transitional state from gynodioecy to dioecy, and there may be ecological advantages for the maintenance of hermaphrodites in colonization processes.

Summary: Masting, the synchronous and highly variable flower or seed production among years within a population, has been observed in many perennial plants. This study focuses on the masting behavior of Veratrum album subsp. oxysepalum, a perennial herb, in different populations in northern Japan. The results suggest that masting provides advantages in terms of avoiding stem damage and seed predation, supporting the predator satiation hypothesis.
