Different Nest Site Selection of Two Sympatric Arboreal Rodent Species, Siberian Flying Squirrel and Small Japanese Field Mouse, in Hokkaido, Japan

Temporal differences in breeding site use between tits and mice

“…While it appears that the proportion of boxes used by mice was relatively low, it did not differ much from results obtained by previous surveys using nest boxes (14/87 nest boxes, from July to October 2010) and natural cavities (21/136 natural cavities, from May to October 2009 and from May to October 2010) (Suzuki and Yanagawa 2012) in the area. The great tit used the nest boxes from early May to mid-July, and there was a mono-modal peak of use around mid-May to early June (Fig.…”

“…Inter-class -bird-mammal interactions, in contrast, are likely to go unrecognised and have been systematically ignored by scientists, despite the fact that they are important to understand cavity-breeding ecology (Czeszczewik et al 2008). As a first step to study these interactions, it is important to try to ascertain the different uses of breeding cavities (Suzuki and Yanagawa 2012) and to clarify the interactions among cavity users (Suzuki et al 2014). In this contribution, we surveyed the breeding sites of great tits and small Japanese field mice, some of the most abundant, similarly sized (10 to 20 g) cavity breeders in Japanese forests, to provide information on the temporal and spatial differences in how they use breeding cavities.…”

“…에 대한 연구가 이루어지지 않았으나, 국외에서 는 우리나라에 서식하는 같은 종을 대상으로 한 연구가 많이 이루어졌다 (Hokkanen et al, 1982;Hanski et al, 2000;Selonen and Hanski, 2004;Hurme et al, 2005;2008;Kadoya et al, 2010;Suzuki and Yanagawa, 2012). III.…”

Efficient placement of nest boxes for Siberian flying squirrels Pteromys volans: effects of cavity density and nest box installation height

“…They currently comprise conifers (29%) including Korean pine Pinus koraiensis , eastern white pine Pinus strobus and Japanese larch Larix leptolepis and broad‐leaved trees (71%) including Japanese white birch Betula platyphylla , Manchurian walnut Juglans mandshurica and Japanese emperor oak Quercus dentata . In the forests, height and diameter at breast height (DBH) of trees (N = 173) averaged 15.3 ± 5.6 (SD) m and 26.0 ± 11.3 cm, respectively, and tree density averaged 692/ha (Suzuki et al 2012, Suzuki & Yanagawa 2012).…”

“…To examine nest‐box selection by Siberian flying squirrels, we recorded cavity densities in the study areas (see Table 1). We have been surveying tree cavities in this area since 2003 (Muraki & Yanagawa 2006, Nakama & Yanagawa 2009, Suzuki et al 2011b, Suzuki & Yanagawa 2012), and for this study we again surveyed the cavities in all the trees in the area. We were able to check all of the trees because the area of forest in this location is very small (Konno 2002).…”
