Co-varying traits in acorns such as seed size and germination schedule are important to influence the behavioural decisions of hoarding rodents. Using acorn pairs from cork oak (Quercus variabilis) (large size and short germination schedules) serrate oak (Q. serrata) (small size and short germination schedule) and qinggang (Cyclobalanopsis glauca) (small size and long germination schedule) with contrasting seed size and germination schedule, we conducted a series of experiments to investigate hoarding preferences in response to seed size and germination schedule by Edward's long-tailed rats (Leopoldamys edwardsi) and South China field mice (Apodemus draco) in semi-natural enclosures. We found that the seed size hypothesis was consistently supported: both rodent species ate more small acorns but hoarded more large ones regardless of germination schedules. However, the germination schedule hypothesis was also supported when similar sized acorns were simultaneously provided, e.g. Q. serrata versus C. glauca or germinating versus non-germinating Q. variabilis. Our results, contrary to the studies from North America, indicate that seed size is more important than germination schedules in determining whether the tested animals eat or hoard a given seed.

The rational design of advanced nanohybrids (NHs) with optimized interface electronic environment and rapid reaction kinetics is pivotal to electrocatalytic schedule. Herein, we developed a multiple heterogeneous Co S /Co S /Cu S nanoparticle in which Co S germinates between Co S and Cu S. Using high-angle annular-dark-field imaging and theoretical calculation, it was found that the integration of Co S and Cu S tends to trigger the interface phase transition of Co S , leading to Co S interlayer due to the low formation energy of Co S /Cu S (-7.

Peanuts grown in tropical, subtropical, and temperate regions are susceptible to stem rot, which is a soilborne disease caused by . Due to the lack of reliable environmental-based scheduling recommendations, stem rot control relies heavily on fungicides that are applied at predetermined intervals. We conducted inoculated field experiments for six site-years in North Florida to examine the relationship between germination of sclerotia: the inoculum, stem rot symptom development in the peanut crop, and environmental factors such as soil temperature (ST), soil moisture, relative humidity (RH), precipitation, evapotranspiration, and solar radiation.

The post-pandemic era has transformed work-life boundaries, driven by factors such as working hours, an increased number of working women and single parents, the implementation of various ICTs, and the rise of flexible work arrangements. This study examines the role of female workers and entrepreneurs in establishing and managing coworking spaces (CSs) designed to improve work-life balance through flexible scheduling and location options. The challenges faced by female entrepreneurs in promoting an inclusive society and economic system are also explored, as well as the benefits experienced by independent workers and teleworkers in terms of networking, social interaction, knowledge exchange, and community building.

The seed germination schedule is a key factor affecting the food-hoarding behavior of animals and the seedling regeneration of plants. However, little is known about the behavioral adaptation of rodents to the rapid germination of acorns. In this study, we provided acorns to several rodent species to investigate how food-hoarding animals respond to seed germination.
