“…Sekijima (1997) also reported that the arboreal habitat use of A. argenteus became active from early summer to autumn, while that of A. speciosus was low throughout the year. Likewise, most of Glirulus species exhibit arboreal activity (Bright & Morris 1992; Minato & Doei 1995) and usually eat nuts, fruits and miscellaneous foods (Vander Wall 1990). Therefore, we suppose that A. argenteus and G. japonicus might potentially become predispersal nut predators.…”

The rodents' predation intensity and discrimination ability toward the predispersal beechnuts ( Fagus crenata ) were investigated using a tree tower in a beech forest, central Japan in 1999 and 2000. In this stand, using seed traps, the densities of fallen viable nuts were 35.1 m -2 in 1999 and 8.4 m -2 in 2000. The vertebrate-damaged nuts had fallen 5.6 and 2.2 m -2 in 1999 and 2000, respectively. Yet, the crop of viable nuts in 1999 was not so rich as that in a mast year. In 1999, predispersal predation by rodents was recognized at 16-19 m above ground through the bagging experiment. In 2000, there were no predispersal predation and yet we captured Apodemus argenteus three times and Glirulus japonicus frequently on the tree. Judging from the facts of their feeding behaviors and the tooth scars left on the cupules and nuts, Apodemus argenteus might have been more responsible for predation to the predispersal beechnuts rather than Glirulus japonicus . Apodemus argenteus population seemed to be abundant on the ground in both years. If the main agent of predispersal predator were Apodemus argenteus , their number shifted to the canopy would be much larger in 1999 than in 2000 according as the crop of viable nuts. In an additional experiment, rodents preferred intact cupules to insect-damaged cupules on the tree, suggesting that they discriminated the quality of the predispersal nuts, even in the cupule stage, through olfactory and/or visual senses. Thus, predispersal nut predation by rodents was prevalent during the limited period in autumn.

“…For these studies, there is a range of vegetative types used in the nest, including leaves, grass, bark, epiphytes, vines, ferns and mosses, by all of the orders where nest construction is demonstrated (figure 2). For instance, leaves and grasses are often used for nest construction by rodents [29,30] and insectivores [31][32][33][34]. By contrast, the Japanese dormouse (Glirulus japonicus) uses a high proportion of bryophytes in its nest [29].…”

The aye-aye (Duabentonia madagascariensis), a primate from Madagascar, builds nests high in trees from twigs and leaves [35], whereas bamboo is an important source of nest material and nest sites for the Monito del monte (Dromiciops gliroides), a South American marsupial [36].…”

Nest construction in mammals: a review of the patterns of construction and functional roles

Nesting behaviour in mammals has been investigated in a wide variety of species but to date there has not been any scholarly review of the incidence and roles of these nests. Not all mammals build nests but, while some large species regularly build nests, nest-building behaviour is more commonly associated with small mammals weighing less than a kilogram. Quantitative data for the amounts of different materials used in a nest are rarely reported but mammal nests are typically constructed from fresh (rather than dead) plant materials. Animal-derived materials seem to be rare in nests, but anthropogenic materials are reported. Few studies have examined the roles these different materials play but more physically robust materials provide support for the structure. Many mammal nests have maternity roles, but a variety of other roles were recognized. A wide range of mammalian orders use nests for resting and environmental protection. Less common roles were as sites for torpor or hibernation, or as a refuge from predation, or the materials may have anti-parasite properties. These different roles were often not mutually exclusive. It is hoped that this review will stimulate interest in the functional properties of mammalian nests. It also suggests various themes that would be interesting areas for future research. This article is part of the theme issue ‘The evolutionary ecology of nests: a cross-taxon approach’.
