Abstract The growth trajectories of trees are not fully understood due to their long life span. We characterized the population dynamics of the canopy tree Castanopsis cuspidata (Thunb.) Schottky in a Japanese warm‐temperate forest over 49 years (1

Mapping the Spatial Distribution of Fern Thickets and Vine-Laden Forests in the Landscape of Bornean Logged-Over Tropical Secondary Rainforests

Autor: Ryuichi Takeshige, Masanori Onishi, Ryota Aoyagi, Yoshimi Sawada, Nobuo Imai, Robert Ong, Kanehiro Kitayama

Publikováno v: Remote Sensing, Vol 14, Iss 14, p 3354 (2022)

Forest degradation has been most frequently defined as an anthropogenic reduction in biomass compared with reference biomass in extant forests. However, so-defined “degraded forests” may widely vary in terms of recoverability. A prolonged loss of

Influences of fern and vine coverage on the above-ground biomass recovery in a Bornean logged-over degraded secondary forest

Autor: Ryuichi Takeshige, Nobuo Imai, Ryota Aoyagi, Yoshimi Sawada, Robert Ong, Kanehiro Kitayama

Tropical secondary forests are widespread in the anthropogenically modified landscapes. Because tropical secondary forests were known to show a steady rate of above-ground biomass (AGB) recovery, they were expected to play a crucial role in carbon se

Productivity and morphological traits of fine roots in forest ecosystems along an elevation gradient of Yakushima Island

Autor: Yoshimi Sawada, Kanehiro Kitayama, Mana Mukai, Shin-ichiro Aiba

Publikováno v: Journal of Forest Research. 24:35-41

We measured the productivity and morphological traits of fine roots in seven forests between 170 and 1550 m along an elevation gradient on Yakushima Island, Japan. Yakushima Island is conti...

Relationships between tree-community composition and regeneration potential of Shorea trees in logged-over tropical rain forests

Autor: Yoshimi Sawada, Nobuo Imai, Ryuichi Takeshige, Kanehiro Kitayama

Logged-over forests are widespread in SE Asia, and these forests vary greatly in tree-community composition ranging from a near pristine to a greatly modified forest due to repeated high-impact logging. It is a critical concern in terms of forest man

The Forest Stewardship Council (FSC) has initiated a new sustainability mechanism, the ecosystem-services certification. In this system, management entities who wish to be certified for the maintenance of ecosystem services (carbon, biodiversity, wat

Size structure, growth and regeneration of tropical conifers along a soil gradient related to altitude and geological substrates on Mount Kinabalu, Borneo

Autor: Tatsuyuki Seino, Yoshimi Sawada, Shin-ichiro Aiba, Kanehiro Kitayama

Publikováno v: Plant and Soil. 403:103-114

Conifers often co-occur with angiosperm trees at high altitudes and on infertile soils in tropical rainforests. To explore the mechanism of conifer–angiosperm coexistence, we investigated size structure, growth rate and regeneration of conifers alo

Community dynamics over 14 years along gradients of geological substrate and topography in tropical montane forests on Mount Kinabalu, Borneo

Publikováno v: Journal of Tropical Ecology. 31:117-128

To understand the variation in community dynamics of tropical montane forests along gradients of soil fertility, death, recruitment and growth of trees (≥5 cm diameter) were monitored over 14 y (1997–2011) in nine plots placed in a matrix of thre
