After eating some seeds, Nuterackers fly over 1 km or more to some area with seeds in its sublingual pouch and cache the seeds in the ground for future use. Each cache contains 1-7 seeds commonly. Caching habitats are in accord with seedlings sites. The quantities of caching seeds are very large. Caching depth is adaptable for seed germination. The Eurasian Nutcrackers have an important effect on seeds dispersal of Korean pine.展开更多

When hoarding seeds, corvids often choose nonrandom locations throughout the landscape, resulting in differential survival of seeds. In the context of habitat restoration, such disproportional storing of seeds in areas suitable for germin- ation and establishment can accelerate expansion and recovery of large-seeded tree populations and their associated ecosystems. Here, we investigate the spatial preferences of island scrub jays Aphelocoma insularis during scatter hoarding of acorns （Quercus spp.） on Santa Cruz Island. We use a large behavioral data set on the birds＇ behavior in combination with seedling surveys and spatial analysis to determine whether 1） island scrub jays disproportionally cache seeds in specific habitat types, and 2） whether the preferred habitat type is suitable for oak regeneration. Our results show that the jays nonrandomly cache acorns across the landscape; they use chaparral and coastal sage scrub disproportionally while avoiding open and grassy areas. The areas used most often for caching were also the areas with the highest oak seedling densities. We discuss the potential role of these findings for the recovery of Santa Cruz Island＇s oak habitat since the 1980s.展开更多

文摘Asymmetric competition occurs when some species have distinct advantages over their competitors and is common in animals with overlapping habitats and diet.However,the mechanism allowing coexistence between asymmetric competitors is not fully clear.Chinese white-bellied rats(Niviventer confucianus,CWR)and Korean field mice(Apodemus peninsulae,KFM)are common asymmetric competitors in shrublands and forests west of Beijing city.They share similar diet(e.g.plant seeds)and activity(nocturnal),but differ in body size(CWR are bigger than KFM),food hoarding habit(CWR:mainly larder hoarding;KFM:both larder and scatter hoarding),and ability to protect cached food(CWR are more aggressive than KFM).Here,we tested seed competition in 15 CWR-KFM pairs over a 10-day period under semi-natural enclosure conditions to uncover the differences in food hoarding,cache pilferage,and food protection between the 2 rodents,and discuss the implication for coexistence.Prior to pilferage,CWR harvested and ate more seeds than KFM.CWR tended to larder hoard seeds,whereas KFM preferred to scatter hoard seeds.Following pilferage,CWR increased consumption,decreased intensity of hoarding,and pilfered more caches from KFM than they lost,while KFM increased consumption more than they hoarded,and they preferred to hoard seeds in low and medium competition areas.Accordingly,both of the 2 rodent species increased their total energy consumption and hoarding following pilferage.Both rodent species tended to harvest seeds from the source,rather than pilfer caches from each other to compensate for cache loss via pilferage.Compared to CWR,KFM consumed fewer seeds when considering seed number,but hoarded more seeds when considering the seeds’relative energy(energy of hoarded seeds/rodent body mass2/3)at the end of the trials.These results suggest that asymmetric competition for food exists between CWR and KFM,but differentiation in hoarding behavior could help the subordinate species(i.e.KFM)hoard more energy than the dominant species(i.e.CWR),and may contribute to their coexistence in the field.
