Spatial arrangement and size of home ranges of Apodemus speciosus inhabiting evergreen broad-leaved forest and adjacent cedar plantation, and migration between these stands .

Language：Japanese Publisher：The Mammal Society of Japan

To investigate the characteristics of home ranges of Apodemus speciosus, we tracked 17 male and eight female mice using radiotelemetry in an evergreen broad-leaved forest dominated by Pasania edulis and an adjacent Cryptomeria japonica plantation in southern Kyushu. Seventeen and 19 home ranges of males and females, respectively, were estimated by the 95% minimum convex polygon method. Home range sizes and distances between them successively detected during the night became larger during the acorn dropping season, from late September to late November, and one mouse moved approximately 100 m within three hours. Home ranges sometimes overlapped among mice in the boundary area of the two forests. Spatial arrangement and size of home ranges, and movement within home ranges of Apodemus speciosus, varied between individuals. Among them, three mice had home ranges that extended into both forests and nests in the cedar plantation during the acorn dropping season. They constantly moved from the cedar plantation to the broad-leaved forest and vice versa. Such mice are thought to contribute to seed dispersal from the broad-leaved forest to its adjacent conifer plantation.

Hata Kunihiko, Kimoto Ryotaro, Sone Koichi . Seasonal Changes in the Colonization Rates of Arbuscular Mycorrhizal Fungi in the Roots of Mature Trees and Seedlings of Cryptomeria japonica . Journal of the Japanese Forest Society100 ( 1 ) 3 - 7 2018

Language：Japanese Publishing type：Research paper (scientific journal) Publisher：THE JAPANESE FORESTRY SOCIETY

In order to examine the seasonal changes in the colonization rates of arbuscular mycorrhizal (AM) fungi in the roots of Cryptomeria japonica, we collected roots from mature trees and seedlings in Takakuma Experimental Forest of Kagoshima University from January 2012 to November 2013. We stained sample fine root segments and observed AM fungi by microscopy. As a result, all the individuals of C. japonica examined in this study were colonized by AM fungi. Colonization rates were low from January to May for both mature trees and seedlings. They drastically increased in June and then decreased until August. They recovered after summer from September till November for mature trees and till October for seedlings, and decreased again. Colonization rates showed quite similar patterns of seasonal change between the two years both for mature trees and seedlings, but were generally higher in mature trees than in seedlings. Colonization rates showed significant positive correlation with mean air temperature in total, but more precisely, they increased with the increase in temperature below 22℃, but decreased above that temperature. Precipitation also showed significant positive correlation with colonization rates, but this seem to be an indirect relationship reflecting the relationship between colonization rate and air temperature.

Language：Japanese Publisher：Tree Health Research Society, Japan

To determine the roles of ectomycorrhizal fungi (EMF) in plant growth at different successional stages, we investigated the growth and ectomycorrhization of Pinus thunbergii and Lithocarpas edulis seedlings, grown on four types of soil : P. thunbergii forest soil (P-Soil), sterilized P-Soil (SP-Soil), L. edulis forest soil (L-Soil), and sterilized L-Soil (SL-Soil) from Sakurajima, where volcanic eruptions have formed various stages of succession. No mycorrhiza formed for either species on sterilized soil. The mycorrhization rate of P. thunbergii seedlings was significantly higher on P-Soil than L-Soil, while the rate of L. edulis seedlings did not differ significantly between these soil types. The growth of mycorrhizal P. thunbergii seedlings was significantly greater than that of non-mycorrhizal seedlings on both forest soils, indicating the importance of EMF in the growth of P. thunbergii seedlings. Conversely, the growth of mycorrhizal L. edulis seedlings was similar to that of non-mycorrhizal seedlings on both forest soils, suggesting that the initial growth of L. edulis seedlings was mainly influenced by nutrients from acorns.

Language：Japanese Publisher：The Mammal Society of Japan

In order to elucidate the effects of thinning on Apodemus speciosus and A. argenteus populations in Japanese cedar Cryptomeria japonica plantations, we conducted population surveys in two sites composed of a plantation and an evergreen broad-leaved forest in southern Kyushu, Japan. In one site, about 50% of the volume of cedar trees in the plantation were cut in September 2012. All mice inhabiting the plantation disappeared just after thinning. New individuals of A. speciosus and A. argenteus began to be captured in the plantation three and six months after thinning, respectively, and both mice species recovered in the third year after thinning, when the ground vegetation had recovered. Meanwhile, in the non-thinning site, the number of trapped mice did not largely change throughout the year in 2012. These results show that thinning should produce pronounced impacts on mice populations through drastic disturbances of habitat condition, and the effects are larger and longer for A. argenteus than for A. speciosus. However, we also suggest that mice populations can recover within three years after thinning.
