Small-scale species richness and its spatial variation in an alpine meadow on the Qinghai-Tibet Plateau
We investigated how the high small-scale species richness of an alpine meadow on the Qinghai-Tibet Plateau, China, is maintained. This area is characterized by strong wind and severe cold during longExpand

Frequency distribution models for spatial patterns of vegetation abundance
In a plant community, measurements of the number of plant individuals, the number of binary occurrences, plant cover, and biomass per unit area have frequently been used to explain speciesExpand

Spatial pattern changes in aboveground plant biomass in a grazing pasture
Using gamma distribution and spatial autocorrelation, it was demonstrated that plant biomass per unit area of a pasture grazed by cattle exhibited two kinds of spatial heterogeneity: small-scaleExpand

134Cs and 137Cs levels in a grassland, 32 km northwest of the Fukushima 1 Nuclear Power Plant, measured for two seasons after the fallout
We measured the levels of radioactive caesium (RACs; 134Cs and 137Cs) in plants and soil in a grassland, 32 km northwest of the Fukushima 1 Nuclear Power Plant, from June 2011 to October 2012. InExpand

Cost-benefit relationships in fronds emerging at different times in a deciduous fern, Pteridium aquilinum
We studied the life-span and ecophysiological traits of "leaves" (fronds) that emerged at different times dur- ing the growing season in a deciduous herbaceous fern, Pteridium aquilinum (L.) Kuhn (inExpand
