“…Some studies have shown that feeding and hoarding behavior of rodents had significant seasonal differences and were seen as an adaptation strategy in response to seasonal changes in food and the environment in Northeast China ( Li et al 2020 ). Our results about survival curves, consumption time, MRT , removal time and fate of seeds also indicated that the hoarding strategies of rodents varied substantially between seasons.…”

“…Earlier results indicated that environment temperature has an important effect on changes in the activity behavior in rodents, with rodent species adjusting their foraging times and activities in response to changes in temperature ( Corp et al 1997 ; Li et al 2020 ). The temperature is similar in the spring (April–May, 1–21°C) and autumn (September–October, 0–21°C) in the research area in 2018.…”

“…The hoarding behavior of rodents is a special type of feeding behavior; it is a vital adaptive strategy for many rodents during periods of food scarcity ( Chang et al 2010 ; Luna et al 2016 ; Li et al 2018 , 2020 ). The hoarding behavior is affected by many factors, including the characteristics of plant seeds, yield, distribution, temporal and spatial changes of food resources, as well as seasonal changes in environmental factors, such as climate and habitat structure ( Willson and Whelan 1990 ; Vander Wall 2001 ; Preston and Jacobs 2005 ; Jenkins 2011 ; Lichti et al 2015 ; Morán-López et al 2018 ; Li et al 2018 ).…”

“…A reasonable allocation of limited food resources, an adjustment of the temporal and spatial abundance, and the use pattern of food help animals utilize hoarded resources to ensure their survival or reproductive activities during food shortages ( Smith and Reichman 1984 ; Vander Wall 2001 ; Lu and Zhang 2005 ; Chang et al 2010 ; Wang et al 2012 ; Lichti et al 2015 ; Luna et al 2016 ). Food resources fluctuate greatly, particularly in the Northeast China in which the seasonal changes in the habitat environment are significant; the climatic environment changes are significantly, and the habitat conditions are unstable (Li et al 2019 and 2020 ). Hoarding food is an important way to manage severe environments, effectively save predation time and energy consumption, and ensure that the rodents successfully survive the winter ( Zhang et al 2014 ; Li et al 2018 , 2020 ).…”

To explore the differences in hoarding strategies of rodents for different seeds in various seasons, we labeled and released the seeds of Pinus koraiensis, Corylus mandshurica, Quercus mongolica and Prunus sibirica in temperate forests of Northeast China and investigated the fate of the seeds in spring and autumn. The analysis showed that the hoarding strategies of the rodents varied substantially between seasons. The seeds were consumed faster in the spring than in the autumn. More than 50% of the seeds in the two seasons were consumed by the 16th day. It took 36 days to consume 75% of the seeds in the spring and 44 days in the autumn. The rate of consumption of the seeds in the spring was greater than in the autumn, and the rate of spread of the seeds was greater in the autumn. The distances of removal for the consumption and dispersal of seeds in the spring (3.26 ± 3.21 m and 4.15 ± 3.52 m, respectively) were both shorter than those in the autumn (3.74 ± 3.41 m and 4.87 ± 3.94 m, respectively). In addition, the fate of different seeds varied significantly owing to differences in hoarding strategies. The seeds of the three preferred species, P. koraiensis, C. mandshurica, and Q. mongolica, were quickly consumed. More than 90% of the seeds of these species were consumed. Only 21% of Pr. sibirica seeds were slowly consumed, and the two seasons had the same seed consumption rate patterns: the consumption rate of P. koraiensis seeds was the highest, followed by C. mandshurica, then Q. mongolica, and finally Pr. sibirica. The median removal times of the two seasons were different, but the rules were the same: P. koraiensis was the shortest, followed by C. mandshurica, and the third was Q. mongolica. In both seasons, the most predated in situ seeds were those of P. koraiensis; the most hoarded seeds were those of C. mandshurica, and the most unconsumed seeds were those of Pr. sibirica.
